What are the functions of resin in plastic bucket production? In the same kind of plastics, when the filler content is high or the inorganic filler in the filler is increased, the shrinkage rate is small. The mold structure that is conducive to improving the molding pressure, increasing the plastic mold filling fluidity and making the plastic part dense can reduce the shrinkage rate of the plastic part. Any process factor that can make the plastic part dense and overflow the low molecular volatile matter before molding can reduce the shrinkage of the plastic part, such as preheating and pressurizing the phenolic plastic before molding. After heating, compacting and mixing in the barrel of the injection machine, the process of transforming loose powder or granular solid into continuous homogenized melt is called plasticization. Homogenization includes four aspects, that is, after the material is plasticized, the composition, density, viscosity and temperature distribution in the melt must be uniform. Metering refers to the preparation work that can ensure the injection machine to discharge the plasticized melt out of the barrel at a constant temperature, pressure and quantity through the plunger or screw, which needs the injection machine to control the plunger or screw during the plasticizing process.

For chemical drums, it is very important to master the temperature. Because temperature has a significant impact on the function of plastic extrusion and parison, improving the extruder temperature can reduce the viscosity of the melt, improve the fluidity of the melt, and improve the screw speed without affecting the mixing and plasticization of plastic. To achieve this goal, we can use electronic temperature controller to make the process temperature stable and save energy significantly. It must be well understood that humidity will affect the drying rate of chemical drums. When the relative humidity in the bucket is low, the pressure difference between the surface and the water vapor in the dryer is large, and the drying speed is fast. The isolation function of chemical drums from oxygen, carbon dioxide, nitrogen and organic solvents can vary by tens or even hundreds of times, and the basic characteristics of plastic containers should be grasped. Therefore, when selecting plastic containers, it is necessary to fully understand that plastic related functional chemical barrels are generally made by molding. Different molding methods often have a great impact on the function and cost of products.

We can also use soap to add a small amount of ammonia water mixture for removal, which can also make the shell of the chemical plastic bucket more shiny. You can also use the heating method to soften the residues on the plastic bucket with the hot air of the hair dryer, and the residues can be easily removed when the viscosity of the residues becomes smaller. Of course, we can also use a very familiar eraser for erasing, but the viscosity of the residue is different, so the erasing time is also different. If there is alcohol, it can be used together with alcohol to make the erasing effect better. There are many ways to decontaminate plastic packaging barrels, not only the above, but also the essential balm we often use has a certain decontamination effect. You can refer to the above content when decontaminating.

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.
