Repair of a plastic container can be made in relation to any plastic product, including:
- the service is in demand, because if the reservoir is damaged, you do not want to throw it away, so it remains only to professionally eliminate the damage that has arisen.
This is especially beneficial in the financial aspect, because repairs require significantly less investment than buying a new product.
Plastic is both strong and brittle material, and if handled improperly, its breakage is inevitable.
Any fall or mechanical impact can lead to cracks. And a container that allows water to pass through becomes useless. But seal the plastic water tank it is quite possible that it will serve properly for some time.
It is quite possible to seal a plastic barrel at home. Let's consider two options for how you can eliminate gaps in plastic drums and other containers.
If you have to repair a container, the water in which is under pressure, you can resort to another method.
VIDEO If the defect in the plastic container is small, you can use epoxy glue. Two-component epoxy adhesive can effectively solve the problem of a leaky plastic tank.
Differs in increased resistance to moisture and chemicals, polymerizes in just 1 hour, non-flammable.
It is necessary to cut off the required amount of glue, knead it with clean hands until a homogeneous mass is obtained, mold a cone from it and insert it into the opening of the tank. Fix securely for a few minutes.
Then you need to wait 2 hours, after which the container can be used.
The epoxy clay-plasticine Contact has proven itself well. Can be used directly under water, resistant to moisture.
restores the shape of products, as well as hermetically fills in voids,
not afraid of not only water, but also oils, solvents,
the repaired tank can be used at temperatures from -40C to + 150C,
within 3-5 minutes, the glue lends itself to correction, and after an hour it can be cleaned, grinded and subjected to other mechanical influences,
the glue is sold ready-to-use.
The cost of this composition is from 150 rubles per package of 50 g.
Also, similar properties are possessed by adhesives "General Purpos Permapoxy PERMATEX" (from 314 rubles for 25 ml) and Plastic Weld Permapoxy PERMATEX (from 320 rubles for 25 ml).
You can purchase epoxy adhesives at most hardware stores, as well as online.
Recently I discovered that a crack of about 4 cm appeared in a plastic bucket at the very bottom.
Is it possible to somehow close it up so that the water does not leak?
Try to glue it with cold welding. If it holds water in the radiator of the car, then it will probably keep the plastic. But I tried to melt it somehow, nothing happens, some kind of plastic is now produced incorrectly))) Excuse me, previous authors.
If your plastic bucket bursts, you can glue or weld it, but this is all only for a while, since the drying out of the plastic is irreversible.
An easy way to resuscitate a plastic bucket: Try using plastic solvent as your glue.To do this, drop a few drops of solvent on both edges of the crack. The top layer of plastic will soften at this point. You will need to join and press firmly on both edges. After about a day, the bucket can be used.
It is important to select a solvent suitable for the type of plastic. From solvents I know toluene for polystyrene, dichloroethane for plexiglass, tetrahydorofuran for vinyl plastic. Pre-check on the rim of the bucket to see if this chemical will dissolve your plastic.
I once repaired a hole, and a rather big one, in a plastic bucket using an old soldering iron. I picked up a piece of plastic that was suitable in consistency and quality, and heated it with a soldering iron, distributed it over the hole, starting from the edges, gradually allowing it to solidify. The only problem is that the "overheated" plastic in this way becomes more brittle. But that was enough for a while.
I think that if this is just a crack that has not yet parted and has not turned into a hole, you can simply run a soldering iron along the crack from the inside and outside. This should be enough to ensure strength, restore tightness)
I myself did not try to glue the plastic buckets, but I saw how it is done. We take an ordinary plastic bag and use a soldering iron to seal the crack with this, smearing it. You can do this with a piece of plastic using a soldering iron again. At the dacha, they watered with such a bucket: the water did not flow.
Insert a plastic bag into the bucket.
The small size of the crack will prevent water from flowing through the bag. If the bucket is stationary, then this is the best method in terms of simplicity and implementation. This is how I repaired a plastic barrel. Instillation with molten polyethylene begins to occur upon deformation.
.already in cold-welding-to-scotch times, but when the plastic bucket had already shown a crack in the bottom, my dad took a piece of rubber from the car camera (well, that, hey, no, no), respectively. the size of a piece of sheet aluminum (var. - duralumin, brass) with a thickness of 1-2mm and made acc. the patch that completely covered the crack, drilled / punched holes around the perimeter for aluminum rivets, made right there in a vice from a 6-10_kv.mm electric wire, applied and riveted.
Dad died in November 2004 (Kingdom of Heaven). the bucket is still according to his brother at the dacha. functions. Soon it will be 14 years old as Dad died, and the "patch" - all 20 for sure.
And here I myself am sitting far from my parental house with a cracked bottom of a plastic bucket and looking for a recipe in the grid. grandfather caught a goldfish. yeah, but the grandmother's trough, damn it, cracked.
I'll throw it out, fuck him, huh? or for "mushrooming" will fit? perhaps.
happiness and health to all kind people and good luck!
So, how to fix a hole, a crack in a plastic bucket? I don’t know how about soldering plastic, small holes in a plastic bucket can still be somehow soldered, but large cracks are unlikely to be done well. There are other options for how to close up a crack in a plastic bucket, I don’t do such nonsense myself, so I read it on the forum. To do this, you need to take some extra piece of plastic, then put it in some kind of dish (but not in plastic), pour acetone, close the lid and wait a little until the piece of plastic softens. Then add the Moment glue and quickly repair everything.
And also, in specialty stores, liquid plastic is sold in tubes, it can also be plugged in a crack in a plastic bucket or whatever you have.
Some advise to apply epoxy glue to the degreased surface and glass fabric on top, and for reliability it is better to do it twice.
One of the reasons for damage to plastic water containers is installation irregularities. Uneven ground and sharp objects can lead to changes in the geometry of the tanks, cracks and leaks. Deformation can also be caused by mechanical influences, including shocks during operation.
Before gluing a plastic water tank, you need to know the composition of the material that was used to make it. Depending on the feedstock, the following types of polymers are distinguished:
Polyethylene (PE-HD) ... It is characterized by a combination of hardness and ductility, which simplifies the plastic processing process. Low pressure polyethylene is resistant to various organic and inorganic media and retains its parameters at temperatures from -50 .. + 80 ° C.Polypropylene (PP-H) ... Differs in increased hardness, tensile strength and chemical resistance.Polyvinyl chloride (PVC-U) ... Withstands temperatures in the range from 0 ... + 60 ° C, as well as exposure to oxidizing media and chemically aggressive substances. In addition, it has high strength and hardness values. The type of polymer influences the choice of method by which damage and leaks of containers are repaired. Repair of plastic water tanks made of plastic with different compositions is performed according to certain technologies.
To repair plastic tanks, there should be no water in them.
The container is freed from liquid, and the damaged area is cleaned and degreased. Then the following operations are performed:
heat up the plastic in the deformed area, melting it to a certain depth; • fill the crack with a heated rope or a piece of polymer;
cool and clean the resulting seam from excess plastic.
The result obtained depends on the observance of the temperature regime and the skills of working with special equipment.

RemPlast is a center for professional repair and welding of plastic products in the city of Moscow, the Moscow region and regions.
Repair of a plastic tank can be divided into 2 types: extrusion and bar (soldering with a hot air gun). The rest of the repair methods are ineffective (glue, sealant, foam, etc.).
Soldering gasoline tanks (gas tank) has its own characteristics. The gas tank from special equipment must be removed from the car before repairing. Some gas tanks can be repaired directly on the car, depending on the nature of the damage and the location of the fuel leak.
During restoration, polymer containers for water do not require special preparation, they must be drained, the place of damage must be protected from the ingress of liquid and cleaned of dirt deposits (if any).
Extrusion is performed using specialized equipment. This method is used to repair loaded products (gas tanks of tractors, trucks and cars, containers with a volume of over 0.5 cubic meters and containers working under pressure). After welding, products do not lose their operational and strength properties - the service life after repair is unlimited.
Welding with heated air (using a hot air gun and a plastic additive) is a less effective method, usually not heavily loaded plastic parts are welded with it. The service life after soldering is from 1 month (depending on the load). This method, due to overheating of the repaired place, is not as durable as the extrusion method, but its unconditional advantage is its lower cost.
Professional restoration of the plastic tank is carried out as soon as possible, if necessary, with the departure of a welding specialist to the work site. Water tanks, fuel tanks, plastic expansion tanks, vertical tanks, storage tanks, large plastic containers, as well as containers for reagents and other chemical compounds are subject to restoration.
Most modern cars, tractors, construction equipment are supplied with plastic fuel tanks, which for a number of reasons break through, crack and break.The cost of gas tanks is quite high, plus the order and delivery of the product can take a long time, the price of work allows you to avoid high costs and restore a damaged gas tank with minimal losses. Soldering the fuel tanks takes about an hour of your time. An example of welding a fuel tank is the repair of the gas tank of the JCB excavator shown in the first photo, the tank was pierced with iron reinforcement, after the restoration of the properties and shape of the gas tank remained the same, the equipment works smoothly.
To weld a gas tank (fuel tank), the customer must provide certain conditions - the tank must be drained, dried from fuel (open the neck and other outlets for several hours, during transportation, keep it open for gasoline or diesel vapors to escape). We solder gas tanks of trucks and cars, snowmobiles, tractors, trucks, buses, truck cranes and other special equipment.
Independent restoration of polyethylene fuel tanks is impossible, if you are looking for something to seal the plastic container - do not try, there is simply no glue for polyethylene and polypropylene, and manufacturers claiming that glue or sealant can seal a crack in these materials are cunning. Polyethylene or polypropylene are repaired only by welding, if a guarantee and tightness of fuel tanks is needed, then it can be achieved exclusively by extrusion welding. There are no special conditions for soldering a plastic water tank, it must be dry. You are wondering - how to seal the plastic tank? - do not hurry! Due to a number of their properties, polyethylene and polypropylene containers do not stick together, sealants, glue and epoxy resins will not help you in solving this problem, and the deterioration of the surface quality due to unprofessional repairs can increase the cost of subsequent work on restoring the product (see photo 3).
The plastic fuel tank is repaired by polymer welding using a welding extruder. Modern plastic containers are made from high quality polymer raw materials. Welding technology allows for the repair of tanks and gas tanks made from almost all types of raw materials. Usually, polyethylene is used as the basis of polymer containers, it is known for its resistance to fuels and chemicals, as well as to shock and external loads. Polyethylene containers are distinguished by their durability in use, storage of food and drinking water in a polymer container is safe for the human body, this is due to the fact that polyethylene does not emit toxic substances and practically does not decompose. Due to the unique chemical and mechanical properties of polyethylene and polypropylene, many manufacturers of agricultural, construction and special equipment have adopted polymer capacitive equipment for re-equipment instead of outdated metal equipment.

Then a similar problem happened - a small hole in the tank was formed in the Brandt WTC machine (well, this is inside which the drum is spinning), the children guessed to throw a ruble coin there, so it broke through the plastic case. the hole is small, the size of the edge of the coin, about 2cm * 2mm, in the lower part of the case.

Fuel tanks for cars can be made of various materials, the main of which are sheet structural steel or conventional plastic, which is rather a composite material.
But no matter what the fuel tank of a car is made of, under certain conditions it can get holes and cracks. Moreover, it may be a microcrack, almost invisible to the eyes, but it is quite enough for gasoline to ooze, filling the car interior with unpleasant vapors.
A crack or a hole in the tank can result from corrosive processes, but this applies exclusively to metal tanks and does not at all apply to composite tanks. However, a crack can also appear on the surface of the composite tanks.
So let's find out how fuel tank repairs are done.
Car fuel tank repair methods
We can conditionally distinguish two types of methods that can be used when repairing fuel tanks. The first technology is hot (welding, brazing). The second technology is cold (the use of adhesives and patches).
Hot methods of repairing a fuel tank are technically difficult and require certain skills and abilities. In addition, welding or soldering equipment is required, as well as an understanding of how thin-walled structures can be welded or soldered.
Cold methods of repairing a fuel tank are somewhat simpler. You only need to adhere to a certain and fairly simple technology. In order to repair fuel tanks, use the so-called "cold welding" or epoxy resin in combination with fiberglass.
Repair of the fuel tank using "cold welding"
There is nothing complicated in this method. They buy a special two-component compound, which is sold in almost all hardware stores or car dealerships. Before applying cold welding, the surface in the damaged area is cleaned of dirt, then cleaned with sandpaper and degreased, for example, with a nitro solvent. It is not recommended to degrease with motor gasoline, as a thin layer of oil film may form.
After that, cut off a piece of cold welding with a knife and knead it thoroughly with wet hands. It is better to work with gloves so that you do not wash your hands later. After that, the defect on the fuel tank is carefully covered with cold welding. And it only remains to wait until the composition polymerizes.
Such a repair of fuel tanks is very simple, but it should be noted that the patch obtained in this way begins to crack over time due to vibrations that are inevitable during vehicle operation.
Repairing a fuel tank with epoxy
This method of repairing a fuel tank is more reliable and is suitable for both metal and plastic (composite) tanks. Its essence lies in the fact that a patch of several layers of fiberglass on epoxy resin is applied to the place of the defect.
The surface of the tank in the place of damage must be prepared (cleaned and degreased). Next, the epoxy is diluted in accordance with the instructions. But besides this, aluminum powder is added to the resulting resin in a ratio of 1:10 (one part of aluminum powder to 10 parts of resin). This filler makes the resin less brittle and more durable.
Several patches of fiberglass are cut out (3-4). After that, a layer of resin is applied with a brush and a patch of fiberglass is applied, then the next layers of resin and fiberglass are applied on top. The patch is rolled with something rubber to completely remove the air. Thereafter, it cures for about 24 hours. The last stage: the surface is smoothed with sandpaper.
The advantage of this repair method is that the patch is durable due to fiberglass and is completely not susceptible to cracking. It completely seals the tank and epoxy is completely indifferent to car fuels, be it gasoline or diesel.
Repair of a plastic fuel tank by soldering
It must be said that this method is not very reliable, since it is difficult to ensure a normal seam around the entire perimeter of the plastic patch.
The method is as follows. It is necessary to find a plastic suitable in its composition to the plastic of the tank. After that, a small patch is cut out of this material. First, the patch is tacked in place with super-glue, and then, using a powerful soldering iron, it is soldered around the entire perimeter of the patch.
It will hold on tightly, but it is not always possible to ensure normal tightness. Microcracks may remain somewhere, which, in principle, can be eliminated with the help of a sealant. But it should be said that the sealant can gradually deteriorate under the influence of gasoline. So this method, although simple, is not reliable enough.
Repair of a metal fuel tank by welding and brazing
It should be understood that with such repair methods, there is always a danger that gasoline vapors that are in the fuel tank may flare up. In order to avoid a fire, the tank is thoroughly washed out of fuel, and only then soldering or welding is used.
Thus, the tank can be welded or soldered only after a certain amount of time required for the fuel vapor to completely disappear.
The safest option is to fill the tank with water or an inert gas to avoid flare-ups. The most popular welding method, which gives the greatest reliability, is argon welding.
The second most reliable method is soldering with a special solder. In this case, the tank is not filled with water. But with both methods, the neck should be kept open so that the air inside, expanding when heated, does not deform the tank.
Fast temporary repair of fuel tanks
The tank can be temporarily repaired by using a common screw and rubber gasket. If a hole appears, albeit a small one, it should be slightly widened to fit the size of the screw. Then a piece of rubber is put over the screw and the screw is screwed into the hole. It is only important to guess the size of the hole so that the screw is screwed in normally.
Plastic is a material that can be chemically neutral. And this characteristic allows the material to be used in almost any area of human life. So, most of the containers used for collecting and storing water are made of plastic today. The disadvantage of this material is its weak mechanical strength. On impact, a crack appears.
The easiest way out of the situation is to buy a plastic water barrel. However, until the crack has spread over the entire plane of the container with water, you can try to repair it yourself. There are several options. If the repair is not successful, the purchase option will remain as the only way out of the situation.
The fact is that it is almost impossible to solder the plastic by itself. From exposure to temperature, it changes its shape, which leads to the emergence of new holes. However, a reinforced seam will make it possible to repair the crack.
It is recommended to use the following types of meshes for repairs:
made of stainless steel;
made of copper;
made of aluminum.
The point is that the metal, even under the influence of water, does not have the ability to oxidize. The soldering procedure is as follows. The secret of success lies in immersing the mesh in the plastic exactly by the amount of its thickness.
To fix the net in the installed position, it must be quickly cooled. Surplus heat is taken away by means of a heat exchanger. An ordinary metal knife can act as the latter.
However, statistics show that in order to use this method, the owner of the damaged container must have some experience. Otherwise, a positive repair result is unattainable.
Almost all epoxy adhesives are two-component. Moreover, epoxy is absolutely neutral to moisture.This glue variant is ideal for container repairs.
It is necessary to prepare the resin in accordance with the manufacturer's recommendations (they may differ depending on the brand) and seal the resulting gap in the plastic container.
It will be possible to start operation in two hours (assuming normal conditions - pressure and temperature).
The video demonstrates the procedure for soldering a plastic bucket (the technology can be applied to the repair of large-capacity plastic containers):

Can you cold weld the hole in the plastic tank? Or what is better to glue? Or what is better to glue?
What kind of hole, what is the mode of operation, a lot depends on it. It is clear that the initial strength (at least the appearance) cannot be obtained.
But the stump is clear, if the tank was somehow made by someone, then a hole in it can be repaired to someone you love. Another question is that it can cost comparable to the price of a new tank ...
The mechanical method of sealing has the right to exist and, say, for a polyethylene tank, the only option. And in terms of strength, perhaps the most reliable. The simplest of the mechanical options, it is stupid to hammer in the plug, chep, and fix it.

Cold. The gun won't fit. There is a narrow gap on top (in the picture on the right) for pouring water, about 2-3 cm wide and about 10 cm long.It is necessary to push through it and grease the edge (joint). The actual crack is right along this junction. I really thought to break it off and re-glue it so that it was convenient to miss it, but I'm afraid it will break along the plane, and not along the joints.

I doubt it will last long.
Outside it is possible without bevel. I'm only afraid that later this container will not fit into the case. She snuggles up to him tightly. If something gets in the way, the sealing of the water intake valve at the bottom will be broken.

For most cases, this logic is flawed. Usually, buying a new thing is a direct monetary loss that will not be compensated by an additional trip to work.
Review on the topic - you need to start with an attempt to seal it with a soldering iron, after a failure, shove a polyethylin bag. Next - to listen to the sensations.

It depends on what kind of plastic. ABS and the like adhere well to dichloroethane and THF, they are poisonous only in liquid form. If the plastic dissolves with acetone, then most likely it can be glued with dichloroethane.
But if it is, for example, polyethylene, then only welding. Moreover, a soldering iron or hair dryer is needed with temperature control, the burnt seam will be fragile.
