Application
Calcium Silicate Board is used as thermal insulation layer of power plant boiler and turbine body, chemical plant cracking furnace and distillation column, steel plant heating furnace, drying oven, paper mill digesting kettle, also the thermal cover on the pipelines in these plants
Characteristic
As a backing insulation materials,they have a very marked effect of energy consevation,as a result of less accumulation of heat and bigger heat protection. After long used,the boards do not shrink,out of shape and turning powder out,insulation performance does not decline . The rate strength of calcium silicate board is the highest in the thermo inorganic material.During the design,it can lighten the all-up weight of the kiln and stove greatly. Using common woodworking tools can be cut to any necessary form,and can be glued and formed with other materials easily. No corrosives and toxicity,there are not exhaust gas and peculiar smell under the high temperature,will not cause the injury and pollution to the human body and environment.It's belong to the products of environment protection.
