Calcium silicate is a new type of environmentally friendly, safe, and efficient insulation material. Its internal structure consists of tobermorite crystals, which, when magnified 50,000 times under an electron microscope, appear like interwoven grass whiskers. The high porosity with almost static air within significantly enhances the insulation effect of calcium silicate. Its interwoven whiskers also grant it relatively high compressive and bending strength, making it lightweight with low thermal conductivity, high-temperature resistance, and robust strength.
Insulation materials should have low thermal conductivity, high strength, and be non-toxic and harmless.
The surface temperature of the insulation layer on the pipeline should not exceed 50℃.
The insulation structure should be resistant to rain, moisture, submersion, and natural disasters.
The heat loss (pipe loss) of the network should be minimal, with high transport efficiency and good economic performance.
The structure should be compact, aesthetically pleasing, and have a long service life.
As society progresses, there is increasing emphasis on environmental protection, leading to the gradual phasing out of coal-fired boilers. The heat necessary for daily living is now provided through centralized heating networks. This heating method generally involves long-distance transport and higher anti-corrosion requirements for high-temperature pipelines. If the external insulation material of the pipeline does not offer good insulation, it will result in significant heat loss, affecting economic benefits. Traditional soft insulation materials tend to sag severely, leading to considerable heat loss and resource wastage. Due to its excellent insulation effect, easy installation, and high compressive strength, calcium silicate insulation material can effectively reduce heat loss over long distances and is widely used in urban and industrial park centralized heating equipment and pipelines, making calcium silicate one of the most ideal materials.
Calcium silicate insulation material not only performs excellently in heating network insulation but also showcases its superior performance in multiple fields. Some primary application areas include:
Building Insulation: Calcium silicate boards are widely used in building insulation, especially in the insulation layers of walls, roofs, and floors. Its excellent insulation and fire performance make it an essential material for energy-saving and safety in buildings.
Industrial Equipment Insulation: Calcium silicate material is used for insulation in high-temperature industrial equipment such as boilers, kilns, and reactors. With features like high-temperature resistance, high compressive strength, and low thermal conductivity, it effectively reduces heat loss and improves equipment efficiency.
Pipeline Insulation: Calcium silicate material excels in the insulation of long-distance transportation pipelines, particularly in the oil, chemical, and natural gas industries, where it significantly reduces heat loss and enhances transport efficiency.
Ship and Marine Engineering: In ship and marine engineering, calcium silicate material is used for insulation of the hull and pipelines, effectively resisting corrosion and moisture from the marine environment, thereby extending the lifespan of the equipment.
Power Industry: In the power industry, calcium silicate material is used for insulation of boilers, turbines, and pipelines in power plants, enhancing thermal efficiency and reducing energy consumption.
