Refractory Mortar Introduction
Refractory mortar is a fire resistant special mortar made of inorganic refractory materials. Excellent fire resistance, oil resistance, salt water resistance, corrosion resistance, can effectively prevent smoke, do not produce drops, do not produce toxic gas, effectively curb the spread of combustion, the site can add water stir construction, simple and convenient.
Refractory mortar is composed with refractory powder, binder and additive. Almost all the refractory raw material can be made into powder for refractory mortar usage. According to its material, refractory mortar ca be divided into fireclay refractory mortar, high alumina refractory mortar, silica refractory mortar and magnesia refractory mortar.
Refractory Mortar Performance
- Excellent fire prevention and fire resistance;
- Inorganic materials, safe and environmental;
- Strong corrosion resistance and weather resistance;
- High strength, strong adhesion and good anti-flow performance;
- Good earthquake resistance, small shrinkage, no empty drum cracking;
- Colorless, odorless, no toxic release in high temperature;
- Excellent construction performance, add water to the construction, simple and convenient.
High temperature refractory mortar is joint material which can serve the high temperature condition. Almost refractory materials can be made into powder to make up refractory mortar. As for its granularity, products vary from each other according to the specific usage, and the granularity is usually less than 1mm or 0.5mm.
Refractory Mortar Types
- According to composition, there are fireclay refractory mortar, high alumina refractory mortar, silica refractory mortar, and magnesia refractory mortar.
- According to binder, there are ceramic bonded refractory mortar, hydraulic refractory mortar, and chemical bonded refractory.
- According to construction method, there are finished products and semi-finished refractory products.
