We must first understand the material the use of plastic barrel
Today many chemical production enterprises in order to ensure the safety and the use of raw materials to the packaging plastic bucket. But we need to pay attention to is, because the production of chemicals with different plastic barrels made of plastic products and other purposes, so the use of plastic barrels of different nature also exist great difference.

The current commonly used materials production of plastic bucket with polyethylene, polyvinyl chloride, polypropylene: three, because the production of the three plastic barrels used in plastics and other additives are different, so never can be used to contain food. In addition, part of the plastic barrel with polystyrene material and ABS plastic products, in has not had a chemical oxidation treatment can also be directly on the surface of a plastic bucket of coating coating. At the same time in order to obtain high quality coating coating, but also useful chemical oxidation treatment, such as ABS plastic products in the after degreasing, can use liquid chromate treatment etching thin.

I believe that through the above content, I hope everyone in the use of plastic barrels before we must first understand the material.
