SA系列二氧化硅消光剂 f China’s GDP, the coating market increases annually by 8~10% on average, which thus drives the development of the coating material market, especially the rapid increase of the delusterant powder market. However, the research on SA Series Silicon Dioxide Delusterant is relatively late, and the research and production of ultra-fine aerogel began in 1984; therefore most kinds of domestic delusterant powder can only meet the product requirements of medium and low-grade coatings. The field of high grade products is mostly monopolized by foreign manufacturers. In recent years, although China has done a lot of research work in this field, most work is still at the trial stage. Moreover, domestic products lag behind the foreign products in terms of transparency, dispersion, stability of storage and efficiency. 我公司在2007年底通过引进国外先进的生产工艺和设备，并与自我创新相结合，采用特殊的合成工艺及有机处理工艺，利用气凝胶大孔容、高比表面与各类树脂折光指数相同的特点，研制开发出了新型SA系列高效消光剂，它的初始粒径从10到15nm不等，聚集体平均粒径为2um，3um，4um，5um（激光衍射法），孔隙率达到1.8-2.0ml/g。产品质量达到国际先进水平。 At the end of 2007, our company introduced foreign advanced production technique and equipment. Combining with self-innovation, our company adopted special synthesis industrial technique, made use of aerogel’s characteristics of macropore, high specific surface and the same refractive index of various resins and developed new-type SA series high efficient Delusterant. Its original diameter varies from 10 and 15 nm, the average diameter of congeries is 2um, 3um, 4um, 5um (laser diffraction), and the porosity reaches 1.8-2.0ml/g. The product quality reaches the advanced international level.
