Plant of polymeric sand products. Technical equipment of the workshop

Polymer sand paving slabs are a relatively new building material. Such an innovation caused distrust on the part of buyers, but gradually polymer cladding proved its superiority over conventional and pressed concrete tiles.

If you also decide to take advantage of the experience of the majority and lay such a tile in front of the house, then for a start it is recommended that you familiarize yourself with its main varieties, disadvantages and advantages. It will also be useful to have information about what styling methods exist.

The main types of polymer sand products

Polymer sand paving slabs can be classified according to different features. For example, products differ in shape and color. Thus, on sale you can find traditional rectangular tiles and products with complex shape. They also differ in thickness and size. Among the varieties, one should single out the material that is made according to different technologies, among them:

dry vibrocompression;
hot pressing;
vibrocasting with the use of plasticizers.

Dry pressing and vibrocasting produce tiles with low porosity and excellent performance. When considering polymer sand paving slabs, you will notice that it has different surface, which can be with a patterned texture or even, as well as smooth or matte. For example, patterned tiles are suitable for paths, which have minimal water absorption and high frost resistance. It is important that the products have a corrugated surface and are not slippery.

Main advantages

Polymer sand paving slabs have advantages and disadvantages, like any other construction material. Among other advantages, manufacturability should be highlighted. Installation of products can be carried out using slab laying machines or manually. Laying is carried out in a short time, and there is no need to prepare the surface. In addition, the described products are very convenient to use. The technology of their installation implies the need for a gap between the plates, which allows moisture to seep in - melted snow and rain. At the same time, puddles will not form on the surface. The tile itself does not need special care.

Polymer sand garden paving slabs reduce the likelihood of injury, because its surface is not slippery, so the material can even be used to equip the pool area. Not to mention the environmental friendliness. Even a significant increase in temperature will not affect the fact that the tile will release carcinogens into the atmosphere. During operation, no cement dust is emitted, which could be hazardous to human health.

This finish for garden paths also repairable. If it is necessary to replace the damaged area, then dismantling the products will be quite simple, as well as putting them in place. Advantages of polymer sand paving slabs are also in plasticity, as well as strength. Products will not break, they are difficult to damage. The tile is afraid only of sharp and piercing objects.

It is durable, and it can be used if the coating is planned to be used for more than 50 years. Paths and areas are aesthetically pleasing. decorative properties material are high. Tiles can be different colors which do not lose their brightness over time and do not fade under the influence of ultraviolet radiation. The shape of the tile has a strict geometry, so it looks great in the garden or on the parking lot.

Polymer sand paving slabs, the types of which were discussed above, also provide ease of storage and transportation. Affordable cost forces consumers to make a choice towards tiles. To pay for square meter coverage will have about 400-600 rubles.

Why else should you choose polymer sand tiles

Polymer sand paving slabs, the price of which is indicated in the article, has many positive properties, among them:

wear resistance;
strength;
low level of abrasion;
oil and petrol resistance;
resistance to chemically aggressive environments;
ease of installation;
durability.

The material is moisture resistant. The liquid does not penetrate into the structure, but collects in drops on the surface. Products are very well tolerated low temperatures: The tiles can be used up to -70 °C. It is lightweight and easy to install, and is also offered for sale in a variety of textures and colors.

Main disadvantages

There are very few shortcomings in the described products. The main one refers to the fact that tiles under the influence of high temperatures can expand. Just like any other material. If the laying technology has not been followed, then the coating may be deformed, which also cannot be called a plus. This is especially true during the hot season. Therefore, the paving algorithm provides for a gap between the tiles within 5 mm. Otherwise, some elements may begin to protrude or warp.

Production features

The production of paving polymer sand tiles provides for the need to comply with a certain composition and method of manufacture. Among the ingredients should be highlighted:

sand;
polyethylene or polypropylene;
inorganic dyes.

As for polyethylene, it should be represented by a material high pressure. The percentage is dominated by sand, which is why the coating got its name. There are special requirements for sand, among others it is worth highlighting:

the need for calcination;
carrying out washing and sieving;
average particle sizes.

Technology features

The production of polymer-sand paving slabs using sand with the desired characteristics makes it possible to obtain products with a homogeneous composition that do not have inclusions and air bubbles. Therefore, such material serves for quite a long time. It is produced in one of the above ways.

The products are based on crushed polymers. They act as a binder and occupy approximately 25% of the total volume. Not only high-pressure polyethylene and polypropylene, but also polystyrene can be used. Sand occupies 75% of the volume, and dyes are inorganic pigments.

Polymer-sand paving slabs, the price of which was mentioned above, are made according to a certain algorithm. At its first stage, all components are mixed in a concrete mixer until a uniformly colored material is obtained. The finished composition is placed in the extruder, where the ingredients are additionally mixed and melted. The mass obtained at the exit is exposed to the press, where the production of paving slabs ends.

Laying methods

Laying of polymer-sand paving slabs can be carried out using one of several technologies. Among others, it is worth highlighting the methods of mounting products on:

crushed stone;
sand cushion;
concrete screed.

The choice of base will depend on the type of soil and the purpose of the future site. For example, a sand cushion can be used in the arrangement of pedestrian and garden paths, as well as sidewalks. If there is heaving soil on the site or the site will be used for parking cars, then the tile is laid on crushed stone. A concrete screed is performed if the tile will be used to receive heavy vehicles.

Work technology

Work on laying tiles must begin with markings. Next, the soil is removed from the surface by 20 cm. The bottom must be compacted and grooves for the curbs formed. Sand is poured into the moat, moistened and compacted. Geotextiles are laid on the compacted surface. Then sand is added.

The sand base is leveled, only after you can start laying. Crushed stone is poured onto the leveled surface, which should be leveled, adhering to the slope. A dry cement-sand mixture is laid out on top, it should be leveled and compacted. Next, the tiles are laid with a gap of 5 mm. Each piece is leveled with a rubber mallet.

Conclusion

At the last stage of the work on the installation of paving slabs, the seams should be filled. For this, a dry cement-sand mixture is used. It is prepared in a ratio of 1 to 5 and then moistened. If gravel is used as a base, the technology makes it possible to form a durable surface that can bear weight. passenger car.

On the construction market the mass of materials characterized by a variety of properties. And many of them can become a source high income for the enterprising person. We include here the production of polymer sand tiles.

Making polymer sand tiles with your own hands is carried out as follows:

Preparation of all components and mixing them.
Melting of raw materials.
Pressing products.
Storage of finished products.

Business prospects.

Purchase of equipment for the production of products

The next thing an entrepreneur will need to do is to buy equipment for the production of polymer sand tiles. And even home production require certain machines.

Line for the production of polymer sand tiles

The technical equipment includes the following items of equipment:

Dispenser - from 30,000 rubles.
Concrete mixer - from 40,000 rubles.
Melting and heating machine - from 350,000 rubles.
Press - from 150,000 rubles.
Molds - from 1500 rubles / piece.

The final price of equipment for polymer sand tiles will depend on the power of the machines, their configuration and degree of automation. The minimum cost of a production line for a mini-workshop and its commissioning is ≈800,000 rubles. And this figure can be much higher if we talk about a more powerful enterprise.

Sales of finished products and shop profitability

The sale of polymer sand tiles, with well-established distribution channels, should bring the entrepreneur a high profit. And given the demand for products, there is no doubt that many customers will be interested in purchasing quality tiles from a direct supplier. It is used for paving roads, interior and exterior cladding.

Products can be sold:

construction shops and warehouses,
developers,
repair companies,
private buyers.

Despite the fact that wholesalers will bring the bulk of the profits, you should not discount private buyers. To do this, a small pavilion can be organized in the workshop, where manufactured products will be exhibited to customers.

The production of polymer-sand paving slabs, as practice shows, will begin to pay for itself quickly enough. On launch small workshop will require an investment of at least 1,000,000 rubles. This will include the following expenses:

purchase of the most basic equipment,
preparation for the work of the premises (conducting light, water and sewerage),
providing a raw material base for the release of the first batch of goods,
company registration.

To calculate the profitability of the planned enterprise, let's take as an example a low-power line with a capacity of up to 50 m 2 of finished tiles per 8-hour shift. It turns out that more than 1000 m 2 of products can be received monthly. Polymer-sand tiles for basement today cost 250-500 rubles / m 2 on the wholesale market. This means that if you immediately sell all the products produced, the entrepreneur can receive revenue in the amount of 500,000 rubles. And these are excellent profitability indicators for a workshop in the small business segment.

For calculating net income and total amount revenue should subtract variable costs:

payment of taxes and salaries,
room rental,
purchase of raw materials,
fare,
Payment of utility services.

Minus all costs, it turns out that with the full sale of products, the entrepreneur will receive a profit of at least 60,000 rubles per month.

1. SAVING:
The price of our paving slabs is low for the benefits that you get by deciding to buy it. Polymer sand tiles are cheaper than good ceramic tiles, which break, cheaper than rubber and WPC (wood-polymer composite) tiles, which do not have sufficient hardness, and not much more expensive than concrete (cement-sand) with all its shortcomings;
2. INCREASED PRODUCT DURABILITY:
The increased durability of Tetto polymer sand tiles is due to a whole range of special technological measures during its production and the UNIQUE COMPOSITION of the polymer composite. At the stage of product release, specially selected and prepared modified polymers and components, special additives and minerals are introduced into its composition, which give the tile additional PROTECTION AGAINST THE ENTIRE SOLAR RADIATION SPECTRUM, additional frost resistance, resistance to aggressive environments and temperature changes, which in turn order increases the durability of the product COMPARED TO COMPETITIVE PRODUCTS.
3. INCREASED PRODUCT IMPACT:

4. ADDITIONAL UV PROTECTION OF THE TILE:
Tetto polymer sand tiles DO NOT LOSE COLOR under the action of sunlight and do not require additional painting, like competitors' products. HIGH UV RESISTANCE is achieved due to the high percentage of sand in the composite, the choice of special coloring pigments, additives, minerals and modified polymers, which significantly Slows down the aging process of tiles from the sun.
5. ADDITIONAL PROTECTION OF THE TILES FROM INFRARED RADIATION:
Most manufacturers of polymer sand tiles DO NOT USE additional protection of the composite from infrared radiation and in best case limited to UV protection. Our company introduces special components into the tiles that PROTECT PRODUCTS from the impact of this negative factor and INCREASES DURABILITY BY AN ORDER.
6. IMPROVED FROST RESISTANCE OF THE TILE:
The entire structure of the material is MICRO-REINFORCED, which gives the tile additional frost resistance, as well as increases the overall strength and durability of the product. Our tiles are perfectly ADAPTED to DIFFERENT CLIMATE CONDITIONS. Reinforcement of the polymer-sand composite gives resistance to frost and temperature extremes. Our company is the FIRST IN RUSSIA TO APPLY and still uses the technology of reinforcing polymer-sand products.
7. INCREASED RESISTANCE TO AGGRESSIVE ENVIRONMENTS:
The unique composition of Tetto tiles provides excellent RESISTANCE TO ALL KNOWN NATURAL EVENT such as acid rain, bacterial activity and lower plants, to heat and frost, hail and hurricanes, to radiation of the ultraviolet and infrared parts of the solar spectrum. The low water absorption of the material adds to its durability and does not allow it to “grow” to its surface and the ice structure in winter, and the ice easily breaks off from the surface when it is cleaned;
8. EASY INSTALLATION:
One of the main advantages of Tetto tiles is EASY TO WORK with it, it is easy to process cutting tools, without cracking at the same time and during the work it DOES NOT BREAK. The installation of polymer sand tiles is SO SIMPLE that, if desired, it can be carried out even by a non-specialist. The material of the tile is viscous, which allows you to screw something to it with a self-tapping screw.
9. LOW WEIGHT:
The low weight of products in comparison with other types of coatings allows you to take away MORE tiles and save a lot on freight. And on exploited roofs, the weight of the tile is of no small importance.
10. AESTHETIC:
We offer a WIDE color scheme tiles. Polymer sand tiles look very AESTHETICAL and will give odds to many floor coverings beauty, variety of textures, shapes, colors.
11. ECO-FRIENDLY:
The water we drink from plastic bottles, and which is fed into the crane by plastic pipes completely normal and harmless. Thus, the safety and environmental friendliness of polymer-sand tiles is confirmed by the LONG-TERM USE OF PLASTIC PRODUCTS IN HOUSEHOLD. The material is environmentally friendly, does not emit cement dust, which is formed during operation concrete slabs, does not emit carcinogenic substances, unlike asphalt in the heat.
12. UNIFORMITY:
All elements of Tetto polymer sand tiles are HOMOGENEOUS IN COMPOSITION and thus such a factor as a different coefficient of expansion is excluded, the coating FUNCTIONS AS A SINGLE STRUCTURE.
13. LOW THERMAL CONDUCTIVITY AND INJURY HAZARD:
It has LOW THERMAL CONDUCTIVITY and high heat capacity, which gives it HEAT-INSULATING PROPERTIES, which is important, for example, for stables, cowsheds, aviaries. When using it as a covering for playgrounds, INJURIES AND INCIDENCE ARE DECREASED, since the tile is warm and has plasticity.
14. COLORS:
Tetto sand-polymer tiles are available in a WIDE VERSION OF COLOR, which are sure to GIVE SOPHISTICATION to any architectural solution. The palette of colors that you prefer to see will not be lost over time, since the material is dyed throughout the entire thickness of the product.

Polymer sand tiles appeared on the domestic construction market relatively recently. Such an innovation caused some distrust among buyers, but gradually polymer slabs proved their superiority over traditional pressed and cast concrete tiles.

Consider the main characteristics of polymer sand tiles, the technology of its manufacture, the scope and procedure for paving slabs on different types grounds.

Technology for the production of polymer sand tiles

When developing polymer-sand tiles, the technologists set themselves the task of creating a durable and frost-resistant material with a long service life. I must say that they succeeded and the performance characteristics of polymer-sand tiles surpassed cement paving stones in many respects.

Park area paved with polymer sand tiles: photo

The working mixture for the manufacture of tiles consists of three main components:

sand of medium fraction (no more than 3 mm);
crushed primary polymers (secondary polymers can also be used - from an economic point of view, this is more profitable);
dyes are inorganic pigments.

The main filler of the tile is sand, it makes up 75% of the total volume. Before use, it is thoroughly washed and sieved. After that, the sand is placed in a special oven and pierced at high temperature.

The entire production cycle of polymer sand tiles can be divided into the following stages:

Crushing or agglomeration of raw materials. If polymer chips are used, then this step can be omitted.
Mixing sand, polyethylene chips, dyes and additives.
Melting of raw materials in an extruder at a temperature of 250°C.
Pressing polymer-sand mass and forming ready-made plates.
Product packaging.

For the manufacture of plates used modern automated equipment. The products at the output are dense and homogeneous, there are no internal and external cracks or voids throughout the entire array of material.

Technical characteristics of polymer sand paving slabs

Specifications tiles depend on the quality of the raw materials used, the structure of the working mixture and production equipment. However, one can distinguish General characteristics polymer sand paving slabs:

Advantages and disadvantages of polymer sand tiles

The combination of a polymer component with a sand filler causes a number of advantages of laying and operating paving slabs:

The disadvantages include the feature polymer products- Under the influence of high temperatures, the material tends to expand. If the paving technology is not observed (the gap between the plates is less than 5 mm), then the coating may deform in the hot season - some elements will begin to warp and protrude.

Scope of polymer sand tiles

Polymer sand tiles are in demand among professional builders, summer residents, owners suburban areas and private houses.

Paving slabs based on polymers and sand are used in the arrangement of:

Polymer sand tiles can be produced in the form of tiles for roofing. In addition, there is a facing tile made of polymers for finishing the facades of the building.

Overview of manufacturers of polymer sand products

On the market, a range of polymer sand products is presented big amount domestic and foreign companies. Among Russian manufacturers of polymer-sand tiles, Namus LLC, Prompolimer LLC, SibTopProm-14 CJSC, Budprom-Technology Private Enterprise and Polimerika LLC have won a good reputation.

OOO "Namus"- a major manufacturer of polymer-sand products. All products of the company are tested in accordance with GOST 3634-99 before being delivered to the market. The main production is located in Tatarstan, and there are branches and sales offices in different cities of Russia.

The polymer-sand tiles of Namus LLC are produced in the size of 330 * 330 mm, 35 and 20 mm thick, basic colors: green, light gray, chocolate and red. The texture of the tile can be of three types: "parquet", "smooth" and "8 bricks". Sidewalk cost polymer-sand tiles about 500 rubles / m2.

In addition to tiles, Namus LLC produces from a polymer-sand mixture: curbs, gutters, well rings, speed bumps, pedestrian crossings, drainage trays, cable protection plates, monuments and storm water inlets.

Company group "Prompolymer", founded in 2006, manufactures products for various market segments: polymer sand products, building metal structures and soft packaging.

The tiles are produced in sizes 330*330 mm, 20 and 40 mm thick. Forms of paving slabs: smooth, broken stone and rhombus. The price of a tile is from 350 rubles / m2. The quality of polymer-sand products "Prompolimer" is confirmed by the sanitary and epidemiological conclusion.

Company ZAO SibTopProm-14(Tyumen) appeared on the market of polymer-sand products recently - in 2012, but already competes with experienced manufacturers.

Paving slabs are available in four basic colors: red, brown, gray and green. Plate dimensions 330*330 mm, thickness - 20, 30 and 35 mm. Paving slabs are produced in three grades - depending on the quality of the feedstock. The cost of tiles of the first grade is 490-620 rubles / m2, the second grade - 430-510 rubles / m2.

LLC "Polymerika" (Yaroslavl region) specializes in the production of polymer-sand tiles and paving slabs. The company's products have been tested for UV radiation, checked for compliance with sanitary and epidemiological standards and radiation safety indicators. Each research is confirmed by the corresponding document.

Paving slabs are produced in the size of 330*330 mm, thickness - 25, 30, 35 and 40 mm. Types of textures: smooth, parquet, curly and paving stones. The price of tiles is 495-630 rubles / m2 (the cost depends on the thickness of the plates).

Tips for choosing high-quality polymer paving slabs

When choosing a polymer-sand tile, you need to pay attention to the following parameters:

Foreign inclusions on the plates indicate the use of poorly processed or low-quality raw materials, white stains are the result of non-compliance temperature regime. The quality of such polymer-sand tiles deteriorates significantly, the strength and durability of the material decreases.

Do-it-yourself polymer sand tile laying

Paving of polymer-sand tiles can be carried out on a sand cushion, crushed stone or on a concrete screed. The choice of base for installation depends on the type of soil and the purpose of the paved area.

Laying on sand is used in the arrangement of garden and walking paths, sidewalks. If there is heaving soil on the site or the site will be used for parking cars, then the slabs must be laid out on crushed stone. Installation on a concrete screed is carried out when the tile will be used to receive heavy vehicles.

Preparatory activities

To work, you will need the following tools:

crowbar, shovel and jackhammer - to remove the old coating and excavation;
trowel, bucket;
rubber mallet;
cord and wooden stakes for marking the site and controlling evenness;
building level;
rake;
concrete mixer - if the tile is laid on a concrete screed;
mop and broom - for filling sand into the gaps between the plates.

The initial preparation of the soil does not depend on the further method of laying the tiles:

Further actions will depend on the type of flooring - sand, gravel or concrete.

Sand paving technology

Work sequence:

The procedure for laying tiles on gravel

After the “bed” for the site is prepared and the curbs are set, the following work is performed:

Pour a layer of crushed stone 10-20 cm onto the leveled surface and level it, adhering to the selected slope.
Tamp the rubble with a rammer.
Pour a dry cement-sand mixture over the rubble (layer thickness - 5-10 cm).
Level and compact the surface.
If significant loads are planned on the paved area, then it is advisable to lay a reinforced mesh before installing the tiles.
Lay the tiles, keeping the gaps - about 5 mm.
Level the surface with a rubber mallet. Slopes to control the building level.
Fill the joints with a dry cement-sand mixture (ratio 1:5) and moisten.

Gravel paving technology produces a durable surface that can support the weight of a car

Installation of slabs on a concrete base

First stage this method similar to those described above: the soil layer is removed, the surface is leveled and curbs are installed. Next, perform the following steps:

Pour a layer of gravel or crushed stone over the entire area (thickness - 20 cm), tamp.
Make a screed of concrete, taking into account the slope of the surface. Screed thickness - 5-10 cm.
Paving slabs are laid on a cement mortar grade M-150 (the proportion of cement and sand is 1: 3). Instead of this solution, you can use tile adhesive - this method is more reliable. tile adhesive In this case, it is recommended to connect with cement mortar in a ratio of 5:1.
Until the solution has completely dried, the platform cannot be loaded and used.
After the "setting" of the solution, sprinkle the surface of the site with sand and fill the seams between the plates.
Moisten the site and wipe the seams with a cement-sand mixture.

Every year there are new and new technologies that improve the properties of familiar materials. Polymer-sand tiles are the product of such innovations. The product is universal in use, practical, durable and competitive from a financial point of view.
