High purity Microsilica
Description
1,The microsilica is a supermicro solid substances, it has a widespread application in the refractory industry.2,It plays an important role in the shaped and unshaped refractories . It fills in the gap of refractory, increasing the bulk density and reducing the apparent porosity, thus the intensity was significantly enhanced.3,It is very active in water to form colloidal particles by adding an appropriate amount of dispersing agent.It can enhance their mobility, thereby improving the performance of castable.4,It has a strong hydrophilic, can enhance the cohesion of the refractory ,at the same time greatly improve the high temperature performance, and prolong the life of the refractory products.
