Product features:
1, high temperature stability: silica fire mud at high temperatures can still maintain good physical and chemical stability, not easy to occur sintering, thermal expansion and thermal shock cracks and other phenomena.
2. Wear resistance: silica mud has high wear resistance and can be used for a long time at high temperature without damage.
3, corrosion resistance: silica fire mud can resist the erosion of corrosive media such as acid and alkali, and can work stably in a corrosive atmosphere for a long time.
4. Good constructability: Silmo fire mud has good plasticity and plasticity, easy to construction and repair.
5. Good sealing: silica mud can form a dense structure at high temperature, effectively preventing the penetration of gases and liquids.
Typical applications:
1. Used for laying mullite heat insulation brick, polyhydrogen brick, clay brick, special heavy brick and high aluminum heavy brick
2.It is used to prevent the air and hot air flow from invading the masonry
3.It is used to prevent the erosion of slag and molten metal on the brick joints
4. Aluminum silicate fiber cotton, blankets, felt and polycrystalline mullite paste
