Problems solved by technology

However, most of the current silicone polyether polymer defoamers can only be used as defoamers in the food field where the reaction conditions are not harsh. Some of the existing silicone polyether polymer defoamers have poor temperature resistance. The defoaming activity will be lost at a high temperature of 80 degrees Celsius, and some cannot adapt to the environment under harsh conditions such as strong acid, strong alkali, and strong corrosion. However, the defoaming environment in the vast chemical industry and metallurgical fields is harsh, and you can choose to adapt to harsh environmental conditions. High-performance defoamers are rare
