How to restore the gloss of the surface of plastic packaging barrels? First, the reason for the mold: whether the cooling system of the mold has water leakage, or whether the sealing system of the mold has been damaged due to corrosion due to long-term operation. If there is water leakage in a single direction of the mold, and the leaking water flows into the mold, causing the barrel wall to be dull, it is only necessary to replace the sealing strip to deal with the problem of water leakage in the plastic barrel. If the exhaust system of the mold is not good, which leads to excessive gas remaining in the mold during production, causing the brightness of the barrel wall to decline, then it is necessary to check the exhaust system of the repair mold. Of course, it may also be the problem of raw materials. First, understand its materials and functions, and adjust a reasonable process formula. If the sol fluidity of the material after heating is poor, the barrel wall will appear to be not bright enough. Properly add some low-pressure resins, improve the barrel temperature, and deal with other related problems.

How to deal with cracks in the plastic bucket? Generally, in the process of manufacturing 200L plastic bucket, the materials used are basically polyethylene, polyester and other plastics, which are then processed by blow molding. In practice, we can use 200L plastic barrels to hold glacial acetic acid, petroleum dangerous goods, acid and alkali corrosive drugs, etc. In general, it has many advantages. For example, in practice, using this 200L plastic bucket is not only not easy to damage and rust, but also relatively simple and sensitive. In addition, it also has excellent oil resistance and strong corrosion resistance. Therefore, in terms of current application, we can use this plastic bucket to package dangerous goods. Its primary characteristics are non fragile, non rusting, oil resistant, corrosion resistant, thermal insulation and moisture-proof. In addition, after the materials are loaded, we can also fold, stack, store, transport, stack and can 200L plastic barrels according to the order and requirements. In this way, not only can users save a lot of space, but also can save some information. This data actually belongs to macromolecular organic compounds, which can exist in various forms, such as liquid, solid, colloid, solution, etc. The capacity of plastic bucket is different due to the different contents of plastic bucket. In addition, 200L plastic bucket can be manufactured by different processing methods. Generally, the materials used can be divided into thermosetting and thermoplastic materials. However, the former cannot be depicted from scratch, while the latter can be used repeatedly in production.

Blow molding is also one of the processing methods for making plastic barrels. More than 1/3 of HDPE in the United States is used for blow molding. The characteristics of blow molding grades, such as melt strength, ES-CR and toughness, are similar to those used for sheet and thermoforming applications, so similar grades are acceptable. Most thermoplastics can be blow molded, and high-density polyethylene is a blow molding material that is widely used. Plastics suitable for blow molding include polyethylene, polyvinyl chloride, polypropylene, polyester, etc. Now there are also multi-layer blow molding and stretch blow molding. It is very reliable and convenient to use the above methods to process plastic barrels, and the manufacturer is constantly developing new processing methods. I believe that in the future, the processing of plastic barrels will be more and more perfect, and the quality of plastic barrels will be more reliable.

Main properties and characteristics of plastic barrels ① A few plastic packaging barrels have poor high temperature resistance and become brittle under high temperature; ② Good resistance to attack and attack, will not produce serious repercussions; ③ It has good general formability and colourability, and low processing cost; ④ Good insulation and low thermal conductivity; ⑤ Good transparency and wear resistance; ⑥ Most plastic packaging barrels have poor heat resistance, high shrinkage rate and are easy to extinguish; ⑦ Poor dimensional invariance and easy deformation; ⑧ Most of the plastic packaging barrels are light in weight and have the same chemical property. They will not produce serious reverberation and rust during operation; ⑨ Plastic packaging barrels are prone to aging, which will affect the operation efficiency and price in the long run; ⑩ Some plastic packaging barrels are easily soluble in solvents, and will melt when touching certain solvents.

With the use rate of 200L large plastic barrels getting higher and higher, more and more old plastic barrels begin to appear gradually, including some plastic barrels that are broken during transportation, so we specially talk about how to repair the cracks on the plastic barrels. Now 200L plastic drums basically contract the transportation of chemical products, and the cost of plastic ton drums is also very high. If the old and damaged ton drums are replaced with new ones, the cost is too high. So let's talk about the repair of plastic buckets. Plastic buckets are indeed carriers for transporting chemical products, even dangerous plastic buckets, but they are not irreparable. The glue specially used to repair the plastic bucket is AB glue, which is composed of two kinds of glue liquids, one is hardener and the other is the glue. The combination of two liquids can achieve good bonding effect of zui, and the temperature must be appropriate. Although the use conditions are harsh, the bonding effect of the plastic bucket is extremely good. The 200L plastic bucket we usually use is always transported on the truck, and damage is inevitable during long-distance transportation. So many enterprises using plastic ton buckets will prepare sufficient AB glue.
