Chemical raw material barrels, no matter how good the products are, there are times when they are bad, when good people lose their temper, when even the best shoes are worn out, and when it rains in good weather, although the same is true for chemical barrels, in There will be more or less problems in the use process. Today we will analyze and analyze the main reasons why the chemical raw material barrels are easily deformed during the use process, and see if there is a good solution;

Many people have such a misunderstanding about chemical raw material barrels. The sealing function of chemical raw material barrels is not good, so it is not true that it is deformed. After the chemical raw material barrel is filled with liquid goods, after the barrel cover is tightly screwed, the pressure inside the barrel becomes smaller after the liquid inside the barrel is cooled, and the external pressure is large, resulting in a pressure difference between the inside and outside of the barrel. Deformation of chemical barrels. The tighter the chemical raw material barrel is, the more airtight it is, the easier it is to deform. In fact, this is a conceptual fault. It is clearly stipulated in the inspection regulations for chemical raw material barrels that they must be sealed and airtight. If the liquid inside is dangerous goods, the chemical barrels required for Class I dangerous goods must be able to withstand the pressure of 30Kpa/square centimeter, while Class II and Class III are dangerous. The plastic barrels that need to be filled should also be able to withstand the pressure of 20Kpa/square centimeter.

The machinery used in the production of chemical raw material barrels in my country is relatively backward, and the wall thickness control points are few, resulting in uneven barrel body, so the standard for chemical raw material barrels is also relatively loose. For example, the wall thickness of two symmetrical points is about 2: 1 scale. In this way, chemical raw material barrels with uneven wall thicknesses are often judged to be qualified when anatomical analysis is performed. In actual use, the chemical raw material barrel will be deformed due to the great difference in the thickness of the barrel wall. This has led to the attention of plastic machinery manufacturing companies, and has now begun to improve this aspect, and most chemical raw material barrel manufacturers have also actively made improvements in mold equipment. Just as Shanghai Xiangtang Packaging Materials Co., Ltd. has been fully prepared for production and sales.
