晶洁辉JJH锆硅灰Zr silica fume

生产工厂：漳州晶洁辉陶瓷新材料有限公司

Producer: Jingjiehui New Ceramic Material Co.

详细描述：锆硅灰、又称含锆微硅粉，系脱硅锆在冶炼过程中，产生的二氧化硅气体经过集尘器冷却收集得到的无定形、粉末状的二氧化硅SiO2，粒径为水泥平均粒径的几百分之一。

Detailed description: Zr silica fume. Synonym: micro silica, silica powder,SiO2.   Amorphouse, gray-white flour, Byproduct of fused zirconia, is captured from   the furnace during the fusion process. Zrsio4=ZrO2+SiO2↑. Particle   size less than 1 micron.

特性：有氧化锆的参与，流动性好，减少水的使用量。不同于工业硅生产过程中收集的微硅粉。表面活性极强

Characteristics: Good fluidity, reduce water, high specific surface   area.

主要用途：不定形耐火材料；UHPC超高性能混凝土、如：摩天大楼、桥梁、水坝、海底隧道等。

Application: Amorphous refractory, UHPC(Ultra-High Performance   Concret)Constructions of skyscrapers, railways, bridges, dams, subsea tunnels   ect, help improving the performance of cement.
