Product Introduction：
Hard calcium silicate stone slab is a common thermal insulation material. The main raw materials of hard calcium silicate stone slab are calcium hydroxide and quartz sand. The size can be customized according to the usage requirements. The finished hard calcium silicate stone slab can withstand a temperature of 1050℃ and has the characteristics of high temperature resistance, good thermal insulation, high strength, fire resistance and heat insulation. It is widely used in industry, construction, agriculture and other fields.
Parameters of hard calcium silicate stone slabs：
Density: ≤230kg/m³
Compressive strength: ≥0.65Mpa
Flexural strength: ≥0.33Mpa
Thermal conductivity: ≤0.065w/m.k
Linear shrinkage rate: ≤2%
Operating temperature: ≤1050℃
Feature Introduction：
High strength: Hard calcium silicate stone slabs have a relatively high strength. The high-strength hard calcium silicate stone slabs can ensure that they are not prone to fragmentation during construction cutting, thereby reducing the loss during the construction process and saving costs. At the same time, the high strength can extend the service life.
Good heat preservation: The thermal conductivity of hard calcium silicate stone slabs is very low. The low thermal conductivity can reduce the conduction and loss of temperature, thereby ensuring the stability of the internal temperature. Therefore, during use, hard calcium silicate stone slabs have excellent heat preservation effects.
High-temperature resistance: The service temperature of hard calcium silicate stone slabs can reach up to 1050℃, which can meet the usage requirements of various high-temperature environments. Therefore, hard calcium silicate stone slabs have excellent high-temperature resistance.
Fireproof and thermal insulation: Hard calcium silicate stone slabs have excellent fireproof and thermal insulation performance. Their main raw materials are inorganic substances, so they are non-combustible by nature and will not produce toxic or harmful gases even in high-temperature environments.
