Examples
- We also can supply active silica powder of every specification , sediment time not lower than 45 minutes
我公司对各种规格的硅微粉均可提供活性硅微粉，沉降时间不少于45分钟。 - At the same time , we further study the affection of the coagulant aids active silica acid and oxidizing agent hydrogen peroxide upon the efficiency of coagulation . results show that the suitable preoxidation and adding coagulant aids can enhance the coagulation effect . the best dose are : [ fe3 + + al3 + ] / [ sio2 ] = l / 2 for active silica acid and 4mg / l for the oxidizing agent ,
同时，对助凝剂活化硅酸和氧化剂双氧水对混凝效果的影响作了进一步的研究，发现经适当预氧化和添加助凝剂可强化混凝效果，适宜剂量分别为：活化硅酸的最佳添加比例为[ fe ~ ( 3 + ) + al ~ ( 3 + ) ] [ sio _ 2 ] = 1 2 ，氧化剂双氧水最佳剂量为4mg l 。 - The study on the core - shell particles shows , one extrenity of silane coupling agents at the surface of the composite particles after adding aps are connected with the fe particles . and the other extrenity outside can polymerize with the active silica . the slick and compact surface of the composite particles shows the obvious core - shell structure . the surface of the composite particles are composed of the combined apex of the element si , o , c , h . the element o is superfluous to the element si
对纳米复合铁粒子研究表明，在aps改性的铁纳米粒子表面硅烷偶联剂氨基一端连接铁粒子，另一端对铁粒子外面，能与活性硅聚合。铁纳米复合粒子颗粒表面光滑致密。核壳复合粒子表面主要由si ， o组成，伴随着微量的c ， h元素的峰，核壳复合粒子表面氧对硅有富余。
