Why does SBS material foam? Why does SBS material foam?
SBS material will encounter mixed air during processing, so that it will expand after entering the heating process, which is the main cause of foaming, and SBS material foaming in hot melt adhesive block will cause product quality decline, production efficiency reduction and other problems.
How to solve the problem of SBS material foaming?
1. Vacuum pump air removal method
The SBS material is placed in a vacuum environment and the air in the material is removed by vacuuming, thereby reducing the possibility of foaming.
2. Use deaerator
A deaerator is a chemical specifically designed to remove air bubbles from a material. In the production process, the addition of deaeration agent to the SBS material can effectively destroy the bubbles in the material, so as to achieve the effect of preventing foaming. #图文扶持计划入口 #图文掘金计划 #橡塑制品 #原创漫画
