粒径对二氧化硅消光粉应用性能的影响

Effects of Particle Size of Silica Matting Powder on Its Application Performance

研究了粒径对二氧化硅消光粉在涂料中应用性能的影响。结果表明,平均粒径越大,消光性能越好;粒径越小,透明性和防沉性越好。因此在选用消光粉时需要根据实际的使用要求来选择合适的消光粉。

The paper studies the effects of particle size of silica matting powder on its application in coatings. The results show that the bigger the particle size is, the better its matting performance is; and the smaller the particle size is, the better its transparency and anti-precipitation are. Therefore, it is necessary to select proper matting powder based on practical application.
