Application of sericite in plastic field
绢云母其独特细鳞片结构和丝绢光泽性能，当其作为增强填料应用于塑料行业时，可以明显改善塑料制品的光学特性，提高塑料制品的气密性、刚性、耐热性和尺寸稳定性，这也正是其与其它无机填料的不同之处。
Sericite, with its unique fine scale structure and silk luster, can significantly improve the optical properties of plastic products, improve the air tightness, rigidity, heat resistance and dimensional stability of plastic products when it is used as a reinforcing filler in the plastic industry, which is also the difference between sericite and other inorganic fillers.
填充绢云母后的塑料制品其机械强度有一定幅度的提高，且塑料不会发生翘曲变形，可赋予产品优良的尺寸稳定性；屏蔽紫外线、抗红外热辐射、阻挡微电磁波的功能；改善制品的耐老化、耐腐蚀、耐热、绝缘等性能；降低制品的燃烧性，磨耗性和浸透性；改善热固性塑料的介电性能等。
The mechanical strength of plastic products filled with sericite has been improved to a certain extent, and the plastic will not be warped, which can give the products excellent dimensional stability; The function of shielding ultraviolet radiation, resisting infrared thermal radiation, and blocking micro electromagnetic waves; Improve the aging resistance, corrosion resistance, heat resistance, insulation and other properties of products; Reduce the combustibility, wear resistance, and permeability of the product; Improve the dielectric properties of thermosetting plastics, etc.
在聚丙烯中加入50%的绢云母粉，制品的抗击穿性能提高了1.3倍，介电常数提高40%以上。当绢云母粉应用于尼龙6中时，可提高尼龙6的刚性和耐热性、降低其成型收缩性等，同时也可较大幅度的降低尼龙6的生产成本，增强市场竞争力。
When 50% sericite powder is added to polypropylene, the breakdown resistance of the product is increased by 1.3 times, and the dielectric constant is increased by more than 40%. When sericite powder is used in nylon 6, it can improve the rigidity and heat resistance of nylon 6, reduce its molding shrinkage, etc. At the same time, it can also significantly reduce the production cost of nylon 6 and enhance its market competitiveness.
添加湿磨绢云母粉的硬聚氯乙烯制品的性能比添加常见的填料活性碳酸钙、煅烧高岭土、滑石粉等的性能要更优越，质量完全符合国家标准，也有利于塑料加工企业降低生产成本和提高产品质量。
The properties of UPVC products with wet ground sericite powder are superior to those with common fillers such as activated calcium carbonate, calcined kaolin, talcum powder, etc. The quality is completely in line with national standards, which is also conducive to reducing production costs and improving product quality for plastic processing enterprises.
