There are two reasons for the deformation of chemical barrels. Melting and creeping are caused by a qualitative change that occurs when the temperature is close to or exceeds the melting point of the plastic. The stress generated by the creep during the setting process is slowly released with the aging, the deformation in a short time is the temperature change, the molecular segment accepts the energy to generate creep, and the deformation within a long time is aging. Either way will affect the life of the chemical barrel, we should pay attention.
Therefore, we should pay attention to the influence of ambient temperature on it when using it. We should avoid the influence of high temperature on it, and the influence of some corrosive products, so as to ensure its use effect.
