What is the process flow of high-temperature resistant calcium silicate board?

Release Time: 2025-07-22

Calcium silicate board insulation material is composed of xonotlite hydrate and reinforcing fibers, and does not contain asbestos. It has a relatively thin board appearance with a simulated wood grain texture, and has a maximum operating temperature of 1050℃.

Specification:

Item	Unit	Index
Bulk Density	Kg/m³	≥ 220
Service Temperature	℃	1050
Rupture Strength	Mpa	≥ 0.33
Compressive Strength	Mpa	≥ 0.65
Thermal Conductivity	W/m.k	≤ 0.065
Linear Shrinkage	%	≤ 2

Advantages of calcium silicate board:

1. Strength improvement.
2. While enhancing strength, the lifespan is also relatively improved.
3. High flexural strength, no deformation under long-term heat erosion.
4. The thermal conductivity is lower than the international standard.

Calcium silicate board is a new type of board made of siliceous and calcareous materials after pulping, molding, drying, and processing. It is a high-performance thermal insulation material without asbestos. It has the characteristics of low bulk density, high strength, low thermal conductivity, high temperature resistance, and can be cut. It is widely used in thermal insulation of boilers and industrial kilns in electric power, metallurgy, petrochemical, cement and other industries.
