Description

Desription of Refractory Mortar:

1.Silica Mortar

Silica refractory mortar is widely used for high temperature industrial equipment such as coke ovens, hot blast stoves, glass kilns, insulating silica bricks, etc. It has the advantages of high refractoriness, high refractoriness under load, reasonable bonding time and so on.

2.Alumina-silicate Mortar

Alumina-silicate mortar has the characteristics of high bonding strength, stable overall masonry structure, good air tightness, good chemical stability, and long service life. It has good workability during use and small shrinkage after burning.

3.Alkaline Mortar

Alkaline mortar is composed of magnesium oxide or magnesium oxide and calcium oxide. It has the characteristics of high refractoriness, strong resistance to alkaline slag, high bonding strength and good sealing performance.

4.SiC & C Mortar

SiC mortar has the characteristics of high refractoriness and strong adhesion that general refractory mortar should have. Besides, it has good volume stability, good alkali resistance, good thermal shock resistance and low thermal expansion.
