What are the test indexes of chemical plastic packaging drums?

Anti-ultraviolet and hardness test: From the engineering plastics, the anti-ultraviolet ingredients in raw materials are closely related to the hardness of plastic packaging barrels. In addition, the intensity of ultraviolet radiation varies in every corner of the world. And in the same place, different colors react differently to ultraviolet radiation.
Anti-corrosion test: When testing the anti-corrosion of plastic packaging barrel, the barrel should be placed in corrosive chemicals, and then the temperature of corrosive chemicals should be kept at 75 degrees Celsius and immersed for 48 hours. No cracking, foaming or deformation should occur in the barrel.
Heat and cold resistance: working temperature: - 30 ~50 C. Destructive test: - 30 ~110 C (softening temperature). Detailed Description: Plastic packaging barrel will be refrigerated at - 18 C for up to 12 hours. Then, a 65 m m diameter and 5 kg weight iron column will be used to lay down the injection point of plastic garbage barrel three times continuously from a height of 1 m. After low temperature testing, the barrel body should not be broken or deformed.
High temperature test: Plastic drums will be put into a room for 3 days. The room temperature is maintained at 90-95 degrees Celsius. After cooling, the surface of plastic packaging barrel should not be damaged, blistered or deformed. Water absorption of raw materials is less than 0.01 to ensure that the box structure will not become brittle or deformed.
