Calcium Silicate Insulation Boards
Product Description
Calcium silicate board for thermal insulation is called microporous calcium silicate. It is a new type of white, hard thermal insulation material with the characteristics of light bulk density, high strength, low thermal conductivity, high temperature resistance, corrosion resistance, cutting and sawing. It is widely used in the thermal insulation and fireproof and sound insulation of equipment pipelines, walls and roofs in the fields of electricity, metallurgy, petrochemicals, construction, and ships. The thickness is usually above 30mm and the density is 200-1000kg/m3.
Calcium silicate pipe is a new type of thermal insulation material made of silicon oxide (quartz sand, powder, silicon, algae, etc.), calcium oxide (also useful lime, carbide slag, etc.) and reinforcing fiber (such as mineral wool, glass fiber, etc.) as the main raw materials, through stirring, heating, gelling, molding, autoclaving hardening, drying and other processes. Its main materials are highly active diatomaceous earth and lime. Under high temperature and high pressure, hydrothermal reaction occurs to boil the product, and mineral wool or other fibers as reinforcing agents are added to regenerate it, and coagulation aid materials are added to form a new type of thermal insulation material.
Features
A. Low thermal conductivity and good thermal insulation.
B. Good thermal stability and small shrinkage value when the temperature changes.
C. Low density, small bulk density, less heat storage.
D. Its specific strength is the highest among the hard insulation materials.
E. It has good durability and has no similar pulverization of ceramic fiber felt after long-term use.
F. No carcinogens - asbestos, sulfur, chlorine and other toxic substances and other low melting point organic binders.
