How to fix a hole in an enamel pan. Enameled pot repair

The topic of repairing old dishes is relevant not only for poor citizens who cannot afford to buy a new bucket or pan. It may also be of interest to jack-of-all-trades. There are many ways to restore damaged surfaces of enameled products. It is better and more reliable to do this professionally in a factory. But if you have a desire to do it yourself at home - please try.

The easiest way is to apply special enamel paints (glass enamels) to the damaged metal surface. They are applied to cast iron and steel products, such as gas stoves, refrigerators, sinks, bathtubs, and, finally, to dishes. To restore damaged enamel surfaces of household and utensils used at room or high temperatures (up to 300-350 degrees), use white enamel. Please read the instructions carefully before repairing. Clean the damaged metal surface with sandpaper, degrease with acetone or gasoline. Then apply enamel according to the instructions.

Repair of enamelware

You can also make minor repairs to a damaged enamel surface that will not come into contact with food with enamel paint produced in aerosol cans, for example, Nitroemal, Bath Enamel, White Enamel. The damaged metal surface must be cleaned, degreased, dried, and then sprayed with a jet of paint from a can, be sure to follow the recommendations.

The second method is more interesting and more reliable, but more laborious. To do this, you must have the following components (in mass fractions): casein - 12, liquid sodium glass - 6, borax - 10, quartz flour - 14, ground glass powder - 5. All components must be mixed well, add water and bring the mass to a doughy states. The damaged metal surface must first be well cleaned of dirt, degreased, dried, and then the prepared mass is applied to it, leveled and allowed to dry. The repaired surface will become waterproof and usable even in high temperature conditions.

Soldering is a good way to repair cookware, but keep in mind that if you use lead-tin solder, the pan will no longer be edible.

You can also repair food utensils at home. To do this, you need to have: an electric soldering iron, solder for connecting metal parts, soldering acid or flux. However, remember that only pure tin, whose melting point is 232 degrees, can be used to solder internal cracks in food utensils.

If you are doing soldering for the first time, then before starting work, you need to tin the soldering iron itself. Clean its working end with a file or sandpaper and heat it up. Then quickly rub it on the rosin. After that, with a heated soldering iron, separate a small part of the solder, which will look like a droplet. In a circular motion, try to achieve uniform spreading of the tin over the surface of the soldering iron so that its end is covered on both sides with a thin layer of tin. If it didn't work, then you didn't clean it well. Try again.

Before soldering, the damaged metal surface must be well cleaned of grease, rust, oxides with a file or sandpaper. Then lubricate the place cleaned and heated with a soldering iron with a flux using a brush or a wooden stick. When soldering food utensils, it is better to apply rosin to the cleaned surface. During soldering, the flux protects the metal from oxidation and creates conditions for better and more uniform spreading of the solder along the crack that needs to be soldered.

Next, apply a drop of tin with a soldering iron and carefully smooth the surface to be treated with it, leading it back and forth with its end. After a drop of solder (tin) spreads over the surface, apply another drop of tin with a heated soldering iron and smooth it again. The melted solder will force the flux (rosin) out of the crack and take its place.

Please note: if a blue oxidation film appears on the tinned surface of the soldering iron, this means that it has overheated. Cool the soldering iron and repeat tinning again. After cooling the sealed dishes, rinse them with water and wipe with a cloth.

If a hole has also formed in the pan or bucket from which the enamel has broken off, then it can be sealed with a metal plate (patch), the size of which should be 5-10 mm larger than the hole. Clean its edges with a file or sandpaper, treat with rosin heated with a soldering iron and apply a thin layer of tin. Then strip the metal patch and treat with rosin. Attach it to the hole and slowly run a hot soldering iron over the edges.

A metal patch can also be glued to the hole using glue of the BF-2, BF-4 brands, but it is not recommended to use them for gluing food utensils, since they are made on the basis of an alcohol solution of phenol-formaldehyde resin.

For gluing metal surfaces, the BF-2 brand glue is considered the best. In addition to metal, they can glue metal to plastic, wood, glass. The surface of the product must be thoroughly cleaned of dirt, dust, rust and grease with sandpaper, then treated with acetone or gasoline, and then glued. Glue should be applied in a thin layer with a brush. After application, it should dry for 40-60 minutes. Then you need to apply a second layer of glue and let dry so that it does not stick to your fingers. Then attach the plate to the hole and press it. Then heat the pot, bucket, other product glued by you for an hour in the oven, stove or on an electric stove.

For bonding metal products, you can also use epoxy adhesives, which include (in mass fractions): epoxy resin (100), dibutyl phthalate plasticizer (10-40), quartz flour or aluminum oxide (10) and hardener (8-10). Their drawback is that the glued parts must be heated at a temperature of 180-200 degrees for 2-3 hours to harden the glue. If such a temperature cannot be reached, then the product glued with epoxy glue can be heated at a temperature of 120-150 degrees. The adhesive will harden within 16-24 hours.

Today, there are many types of adhesives in household chemical stores. Universal are considered "Moment", "Stele", "Second 505", "Supercement". But before you buy, do not forget to carefully read the instructions.

You can also eliminate a hole in household utensils, which you feel sorry for scrapping, in this way. To do this, you need a hammer that is well mounted on the handle, since a loose one will only spoil the work, and besides, it is dangerous to use it. As well as a hacksaw, a chisel, an anvil, a thick metal plate or rail, pliers, a vice for clamping parts during their processing, wire cutters to bite a thick (aluminum or copper) wire if there is no hacksaw or chisel.

Prepare a rivet from aluminum or copper wire. To do this, clamp a piece of wire in a vise, and in their absence, with pliers, and with light blows of a hammer along the edges of the wire, make it a “hat”, like a nail. Insert the wire into the hole in the item you are repairing and lightly tap the edges of the wire on the opposite side with a hammer until the rivet closes the hole in the item. Wash the dishes and wipe with a clean cloth.

Repair your pots and buckets, but remember that only materials that are harmless to health can be used as food utensils.

The pan was leaky and a hole formed in its bottom. Don't rush to throw it away. Having the skills of owning a soldering iron, you can repair the pan yourself.

Preparatory work

First of all, the area of ​​\u200b\u200bthe pan on which the hole has formed should be carefully cleaned first with a file and then with sandpaper. At worst, if there is no file, a file will do. After thorough cleaning, the surface around the hole must be treated with flux or soldering acid.

If the pan is not enameled, but aluminum, the cleaned surface will instantly be covered with a layer of oxide and soldering will be difficult to the point of impossibility. Therefore, immediately after stripping, the treated surface must be covered with a layer of molten rosin.

Ludim

We turn on and heat up the soldering iron to the operating temperature (by the way, the power of the soldering iron should be large enough to ensure good heating of the pan at the repair site). If a high-power soldering iron could not be found, the pan can be heated over the flame of a gas stove immediately before soldering.

We grab a small amount of rosin with a soldering iron tip and apply it in a thin layer on the surface of the pan around the hole. The resulting film of rosin will not allow the surface of the metal from which the pan is made to oxidize.

We collect a small amount of solder with a sting and slowly, conscientiously apply it to the area around the hole. The surface is tinned, we move on.

soldering

We warm up the place of future soldering with a soldering iron tip. Picking up solder in small portions, diligently fill the entire hole in the pan with it.

If the diameter of the hole in the leaky dish is more than 3-5 mm, we recommend that you do not fill it with solder, but apply a patch of a copper plate slightly larger than the hole.

The copper plate should be cleaned with sandpaper and treated with soldering fluid. Next, we apply a copper patch to the prepared and tinned surface of the pan and thoroughly heat the entire surface of the patch with a soldering iron. From heating, the solder on the surface of the pan will melt and securely fix the patch.

If your favorite pot has started to happen, try soldering it. With the help of this method, it is possible to increase the life of this necessary dish. You need to solder according to every rule, because the data on the operation of the pan (high temperature and water) can lead to the formation of a new hole.

You will need

• - solder;
• - copper plate;
• - a file or sandpaper;
• - gasoline, flux or "soldering acid";
• - soldering iron.

Instruction

1. If the hole is small, take a piece of aluminum wire or tin solder for soldering. For a large hole, find a piece of copper plate and cut out a patch slightly larger than the hole.

2. Before you start soldering saucepan, clean the bottom surface with a file, file or sandpaper to the metal itself so that there are no deposits, also polish the copper plate to a shine. Degrease the surfaces with gasoline or another solvent, then lubricate with flux with a brush (flux is necessary to completely clean grease blockages and remove oxide films from metal). Instead of flux, it is allowed to use "soldering liquid" or "soldering acid".

3. Take a soldering iron, heat it up and dip it in rosin or ammonia powder (to clean it of metal oxides). If there is light smoke, the soldering iron is ready to go. Touch the solder with the tool and hold it there until it is completely covered with a sparkling film. After that, grab a little solder with a tip and transfer it to the place of soldering. Level the surface of the bottom of the pan around the hole (tin the junction).

4. Take the solder with the tip of the soldering iron and transfer the solder needed for a strong attachment to the place of soldering. Small holes can be completely filled with solder. To fix the plate, apply solder around the hole, smooth it out and apply a patch on top. In order for the plate to grip and fix perfectly, additionally heat the entire surface of the patch with a soldering iron.

5. After the solder has cooled, wipe this place with a damp cloth and clean it with a file or sandpaper.

6. If you need to solder aluminum saucepan, note that this is somewhat more difficult, because aluminum is difficult to solder. So that an oxide film does not ripen on the surface, immediately after stripping the junction, immediately fill it with pre-molten rosin. Conduct soldering with a hefty strong soldering iron (at least 100 W). Use 80% or 95% tin, 20% and 5% bismuth solder, respectively. Pick up the flux from stearin or paraffin. If you fulfill all these data, you can easily solder saucepan from aluminium.

Even the most tidy housewife has such troubles as a burnt dish. One has only to turn away - in the blink of an eye, the food being prepared manages to turn into coals and, in addition, tightly stick to the bottom and walls of the dishes. Food burns exceptionally easily in aluminum pans, so much so that the elimination of the consequences can puzzle any housewife. However, you should not put an end to powerfully burnt dishes. clear aluminum saucepan permitted with the help of several available means.

You will need

• - soda;
• - sponge for washing dishes;
• - plastic brush;
• - a jar of silicate glue;
• - laundry soap;
• - a huge capacity for boiling.

Instruction

1. Use a spoon to scoop out leftover food from the burnt aluminum pan. Don't try to scrape saucepan to remove the burn, this will only scratch the coating and lead to damage to aluminum cookware.

2. In primitive cases of food burning, use the method proven and available at any time to the hostess. Pour into aluminum saucepan so much water that it reaches the end of the burnt line on the walls of the dishes. If only the bottom is burnt, pour water 1-1.5 cm above the bottom of the pan. Put citric acid or baking soda in this container at the rate of: 1 tsp. for 1 liter of water. close saucepan cover, put on fire and boil for 10-15 minutes.

3. When the pan burns stronger than usual, boiling with one soda may not help the dishes. In this case, stock up in the store with a jar of silicate glue. Pour in saucepan liter of water, pour a tablespoon of soda into it, add the same amount of silicate glue. Stir the resulting solution and close saucepan lid. Boil this mixture on fire for at least 30 minutes. Later, turn off the fire and leave saucepan cool down with the solution. After that, pour the cooled mass out of the dish and lightly rub its walls and bottom with a plastic brush.

4. If the clogging of the pot has spread to the outside of the pot, try cleaning the entire pot by boiling it in a larger pot. Dirty dishes should fit freely in this container. Pour the burnt dishes in a larger container with water so that the water is on a tier 1-1.5 cm above the pan being cleaned. Rub laundry soap into the container and add transparent silicate glue there. For one liter of water, the ratio in grams of soap and glue is 20:10. Boil the resulting mass for 2-3 minutes and leave to cool completely. Later, wash the cleaned aluminum saucepan running water with a soft sponge.

Note!
Do not use various hostile acids and abrasive substances to clean aluminum pans. From them, the surface of aluminum is damaged, and metal particles later enter the food.

Aluminum hard to solder. When soldering, an oxide film forms on the surface. But a lot of home appliances, car parts and mechanical parts are made from aluminum. If the device is out of order, not everyone can afford to buy the newest one, especially since the old one is absolutely allowed to be repaired on their own.

You will need

• -sandpaper;
• - ammonium chloride;
• - zinc chloride;
• -water;
• - steel filings;
• -rosin;
• -tin;
• -bismuth;
• -gloves;
• - soldering iron.

Instruction

1. First you need to prepare the surface for soldering. Clean it of dirt, dust or paint. Clean with sandpaper or a file and degrease with alcohol. Be sure to dry the surface, because raw aluminum is unsolderable. Prepare a flux in advance, one that helps to remove oxide films. The flux can be prepared in the following way: 10 g of ammonium chloride and 30 g of zinc chloride must be dissolved in 60 ml of water. Mineral oil can also be used as a flux.

2. Melt the rosin and add fine steel filings to it. Use a hot soldering iron to apply this solution to the seam and slowly add solder, continuously running the soldering iron over the seam.

3. For a stronger seam, special bismuth solders are used. Such solders can be made independently. It is necessary to melt tin and bismuth in a ratio of 19: 1. After that, apply this mixture to the surface previously lubricated with rosin. Do not forget that during each work the soldering iron must be heated.

4. Another fun and effective method. The surface of the aluminum part must be cleaned with sandpaper and a few drops of an intensive solution of copper sulfate should be applied. Connect the part to the negative pole of the current source (battery, accumulator). It is necessary to connect a copper wire to the positive pole, which touches the copper sulfate solution at one end, but at the same time does not touch the aluminum. The point of this method is that a copper coating should form at the place of soldering, on which it is allowed to solder using the usual method.

Note!
After soldering, be sure to clean the seam from clogging and oxidation.

Helpful advice
When soldering a thin surface, it is allowed to use a soldering iron with a power of about 50 watts. For an aluminum part 1 mm thick - 90 W. And for a thicker sheet of aluminum, before everyone else, you need to warm up the surface perfectly with a soldering iron.

Rosin + soldering iron.
But I wouldn't cook in it.
Buy a new pot

Answer from Need to think.[guru]
Yes, it is easy to drill a 2 or 3 mm hole in this place with a drill and pick up an aluminum wire under it and make a rivet out of it and rivet it.

Answer from Toma[guru]
aluminum is very flexible
If the hole is small, you can simply flatten the metal. And the hole will disappear
I put an ax butt under the hole in the bottom of the pan. And from the inside she tapped with a hammer. Simple, accessible and effective)))
Success!

Answer from Truculentus[guru]
Tea is not a war already / yet, you can buy a new one. But aluminum cookware is relatively harmful, stainless steel is better.
Although the idea with rivets is not a bad one. A lot of fuss with soldering.

Answer from sergey petrov[expert]
Yes. 1 Take an aluminum wire and cut it to a certain size
2 insert it into the hole
3 choose a hard place
4 put the pan upside down, the wire should stick out a little for riveting
5 with a hammer, hit it with a hammer until the wire flattens, then put it on the bottom and flatten the other side
6 must be tight

Answer from Jem 78[guru]
it is forbidden.
only welding, only hardcore.

Answer from Shaltaj-boltaj ljuis kerrol[guru]
you insert a bolt with two washers on both sides and tighten it with a nut with handles, then you tighten it again

Answer from Woe from Uma[guru]
My grandfather rivets them at times with aluminum wire ...

Answer from svan[guru]
and if the usual rivet, click and still minted

Answer from Arthur Zarembo[guru]
Yes, you can!
You take a piece of aluminum wire, mm long. 5, and wider than the hole, heat it up to the point of melting, so that the tip melts, then sharply plug it into the hole of the pan, part of the soft metal will pass through the hole and harden quickly, then it’s a matter of plying it with a hammer, on some hard lining. In principle, it is possible to bungle the same without melting, that is, just drive a piece of aluminum, flatten it, but it is more difficult to achieve tightness this way. When the metal is liquid, it adheres more closely to the contours of the hole.

Answer from Nikolai svirjaev[guru]
you take a riveter sold in a hardware store, pick up a rivet of a suitable diameter, insert it and pull it out. five minutes of work

Answer from Yury Vasilevsky[guru]
It’s understandable to rivet, but my grandmother came up with such a thing that is not reliable, but it’s enough to cook a fish for a cat for 5 minutes: cellophane, from sausages, for example, melts over a fire and burrows into a hole, then more carefully until it’s hot, it does the same with plastic buckets .

Answer from Alex Mishin[guru]
I was doing.
I put the pan on the anvil (a sledgehammer, an ax butt, etc. is suitable) and with the help of a beard, with a hammer, first carefully tap the hole along the perimeter towards its center (at a distance of fractions of a millimeter from the edges of the hole), and lastly - one strike on the center of the "undermined" metal.
So minted pots serve me for decades. And I saw pans that the masters "repaired" by driving in a rivet - they flow from the very beginning!

ENAMEL RESTORATION

ON DAMAGED ENAMEL CARE

Enamelware is beautiful, convenient, hygienic, you can not only cook food in it, but also store it, and for quite a long time.

The enamel coating in the dishes protects food from the penetration of harmful metal ions, moreover, bacteria are not able to multiply on the smooth surface of the enamel.

Enamels (glass enamels) deposited on metal are fusible, transparent, white or colored glasses; they serve to protect the metal from corrosion and to give metal products a beautiful look.

Enameled cast iron cookware does not require special preparation before use. Simply wash with soap and hot water. The dishes are harmless, hygienic and resistant to food acids (vinegar), alkalis and salts.

Enamel of the following colors will be absolutely harmless: cream, white, gray-blue, black and blue. All other enamel colors, especially bright ones, contain chemical compounds of manganese, cadmium and other metals in large quantities. Therefore, when choosing enamelware, pay attention to the color of the enamel, and even better, look for the GOST marking.

But this dish also has its drawbacks: sometimes it is too heavy, and most importantly, when it is struck, the enamel often breaks off. After that, enamelware loses its resistance to acids and alkalis and quickly fails: the metal under the chipped enamel rusts very quickly, sometimes even through and through.

If the enamel is already chipped, try to repair it. However, keep in mind that it will no longer be possible to ferment cabbage, store milk, and cook jam in dishes with a repaired enamel coating.

To restore the damaged enamel layer on household utensils used at home at room and high temperatures (up to 350 ° C), for example, gas stoves, gas water heaters, pots, the industry produces white enamel KO-5102. Enamel is applied to a cleaned and primed metal surface by spraying a jet from an aerosol can.

TECHNOLOGY OF RESTORATION OF ENAMEL COATING OF POCKET WITHOUT SPECIAL EQUIPMENT

Method 1. Putty for enamelled surfaces:

kaolin 225 g, finely ground ruffled 60 g, calcined borax 40 g, sodium silicate powder 30 g, powdered glass 20 g, slaked lime 20 g, water 50-125 ml.

After thorough mixing of these substances in a porcelain cup, a homogeneous mass is formed. The cracked enameled surface is cleaned, degreased and rubbed with putty. Drying lasts 48 hours.

Method 2. Putty for enameled surfaces:

13 parts casein, 4 parts slaked lime, 10 parts soda ash, 6 parts sodium silicate, 15 parts ground quartz, 5 parts crushed glass, 50 parts kaolin.

The putty is moistened with a little water before use and stands until the casein combines with alkalis. Then the putty is diluted to the consistency of batter, smeared on the places from which rust and grease must first be removed, and left to air dry.

Method 3. Putty for enameled surfaces:

Mass in parts

Casein 12, Liquid sodium glass 6, Borax 10, Quartz flour 14, Powder of crushed glass 5,

All components are mixed and water is added until a pasty mass is formed; the damaged area is well cleaned, degreased and the prepared mass is applied to it. After drying, the coating becomes waterproof and withstands high temperatures well.

Scratched dishes are restored by polishing them with pastes, which are prepared by mixing white magnesia, chalk powders, iron oxide (“crocus”), tripoli, and adding water.

Adviсe

With a sharp change in temperature, the enamel cracks, so you can not put an empty pan on a hot stove.

When tasting food, do not hit the spoon against the edge of the pan to shake off the remnants, it is better to stir in it with a plastic or wooden spoon. Try not to drop it. The enamel begins to chip off, chips may appear at the bottom.

It is impossible to cook in a pan with broken enamel - substances harmful to health get into food (you can be poisoned by metal compounds). You shouldn't even boil water in it.

The second drawback is that food in it can burn even more than in aluminum. Therefore, you should not cook porridge in such a dish.

It is best to cook cabbage soup, borscht, soup, vegetable stew, kissels and compotes in enamelware.

You can boil pasta, rice in it - but be sure, as soon as the grits are poured (into boiling water), you must immediately stir so that the grits do not stick to the bottom.

Before using enamelware for the first time, it must be washed with warm water and liquid detergent and wiped dry.

A new pan can be tempered. Pour water into it to the brim, add 2 tablespoons of salt (per liter), boil, let cool and then drain the water.

Choose the color of the pan when buying, preferably dark, and the bottom is better when blackened.

The thicker and more massive the cookware, the better it resists impacts.
