Powders are involved in many industries and fields. It can be said that powder technology is one of the basic technologies supporting high and new technologies. The so-called powder technology includes two aspects, one is the design and manufacturing technology of powder particles, and the other is powder processing technology, that is, how to add powder to other substances to exert its unique effect. Adding ultra-fine mesh talc powder masterbatch to plastics can significantly improve the rigidity, creep resistance, hardness, surface scratch resistance, heat resistance and thermal deformation temperature of plastic products. Quite fine talc powder can also Improve the impact strength of plastic products. It also has a lubricating effect after addition, can promote flow and improve the processing technology of plastics. 1. Application in polypropylene resin: Talcum powder is often used to fill polypropylene. Talcum powder has a flaky structure characteristic of lamellar configuration...
