1000℃ Calcium Silicate Insulation Board

1.The main constituents of 1000℃ calcium silicate insulation board is xonotlite (quartz and lime as raw materia) and reinforced glass fiber,no asbestos.
2.It is a kind of high efficient energy-saving material with temperature limited 1050℃. 
3.Characterised by low bulk density,high specific strength,superior heat resistance,outstanding thermal insulation,excellent durability,chemical corrosion resistance,easy to be cut by saw and easy installation.

This board can be sawing,drilling,milling,digging.Other sizes also can be customized.

 Features

 1.Low bulk density,low heat storage,low thermal conductivity;

 2.Good thermal stability,small linear shrinkage when heating;

 3.High mechanical strength,excellent creep resistance;

 4.Long service life,no pulverization such like ceramic fiber blanket;

 5.Safe and clean operation-contains no carcinogens,free from asbestos,suiphur and chloride.

 Application:

 1000℃ calcium silicate insulation boards are used on all kinds of industrial branches to provide high quality   insulating backing.

 In kiln system,it is not exposed to the fire.Detailed application as below:

 1.Cement industry:preheaters and cyclone separators,decomposition kiln,tertiary air duct and cooler

 2.Nonferrous metallurygical industry: aluminum power calcinerand electrolysis groove,

 3.Petrochemical industry: splitting furnace,catalytic cracking furnace,petroleum pipeline,underground heat-   flooding

 4.Metallurgical industry(steel plant):hot-rolling heat furnace,cool-rolling mill set,RH vacuum degassing   furnace,smelters,hot deformation and heat treatment plants

 5.Power plant:preheat stove,pipe

 6.Glass industry:melting furnace andrecuperator,annealing furnace and cooling channels

 7.Ceramic industry: chamber and tunnel furnace
