After using silicone powder in PP0 direct granulation, due to excessive use of silicone powder, it can be improved by appropriately reducing the amount of addition. The recommended addition amount is usually 0.5%. If other additives are added at the same time, reduce accordingly. The total amount of the two additives should be controlled at 0.5%-1%. Manufacturers can debug according to different equipment.
Some manufacturers believe that powdered silicone additives can be stirred evenly, and adhering to PPO particles will add white oil in one granulation process, resulting in insufficient lubrication in the second granulation process.
The reason for the lack of lubrication in the second granulation is that the lubricant properties of silicone additives and white oil play a role in the first time, while the white oil evaporates in the second time, but the silicone additive still exists, resulting in insufficient lubrication coefficient, which leads to insufficient lubrication in the second process. After
using silicone additives, no white oil needs to be added. Baozhuan New Material Silicone Powder is a polymer plastic lubricant. Using the principle of physical dispersion, it can be effectively and evenly dispersed on the surface of the particles, and it is resistant to 400 degrees high temperature and non-volatile.
