Micro silicon powder as a new raw material, widely used in refractory industry. It plays an important role in the improvement of the refractory material. Performance:
(1) the traditional refractory material has numerous pores, micro silicon powder filling in the pores and improve the bulk density and to decrease porosity and strength can be significantly enhanced.
(2) micro silica fume has strong activity, in water to form colloidal particles, with the addition of appropriate amount of dispersant, increase liquidity, so as to improve the performance of the casting. (
3) micro silicon powder in water to form - Si OH groups, with strong hydrophilicity and active, can enhance the resistance to fire cohesion, and improved on the high temperature performance and prolong the service life of refractory products.
Micro silica powder is widely used in refractory industry. Practical applications in the following areas:
(1) instead of pure aluminium oxide clay refractory.
(2) as an additive in the production of an amorphous refractory product, its strength and high temperature performance are greatly improved.
(3) as a whole casting with coagulant drums.
(4) other refractory products of the adhesive agent, binder, coagulant, additives.
