Brick of heat insolation of compound light qualitative heat preservation and general firebrick are compared, weight is light, in-house and even cloth has small air hole, porosity is taller. Accordingly, the quantity of heat that can assure boiler setting be lost is fewer, the charge of fuel can drop accordingly, light qualitative brick also means smaller harbour quantity of heat at the same time, because this litre of gentle refrigeration is faster, allow to accelerate periodic operation. Firebrick of heat insolation of light qualitative heat preservation applies to 900 ℃ ～ the temperature limits of 1650 ℃ .
Brick of heat insolation of compound light qualitative heat preservation, high temperature resistant, bulk density is big, strength is great, wear-resisting, fight soda acid to erode. Use extensively at metallurgy, chemical industry, electron, the furnace of high temperature kiln such as glass; Brick of light qualitative heat preservation has proportion small, intensity tall, coefficient of thermal conductivity low, heat proof quality good, use temperature is advanced characteristic, of the industrial kiln heat that uses extensively at the industry such as national defence, chemical industry, metallurgy, mechanical, building materials, electron, cooking, shipbuilding, medicine, balata build go to, much better to the heat preservation function of oversize kiln furnace.
The item characteristics of the brick of heat insolation of compound light qualitative heat preservation that flourish Cheng Naicai produces:
1, rate of low heat conduction, low thermal capacitance, low matter content;
2, high strenth, good heatproof shake performance, acid-proof alkaline atmosphere is corroded;
3, dimension precision is tall.
Because compound light qualitative heat preservation contains many stoma in adiabatic brick, very bigger than the surface, the be heated when using and fall like self-prossessed action in bear, the easy happening that systole is out of shape and make heat proof quality is reduced. Accordingly, stability can maintain to ask to have good bulk stability namely in asking to pledge the bulk of heat preservation brick and appearance are using a process for a long time gently. Otherwise, contractive action can bring about body of heater to the structure is out of shape and produce crackle, increase heat loss due to radiation.
Accordingly, heat-resisting function is a of brick of light qualitative heat preservation main index. The hear resistance of brick of light qualitative heat preservation allows to use temperature not to depend on normally their fireproof degree, basically is to depend on resistance is heating action produces contractive metabolic ability. To the heat-insulating material of same breed, use temperature is commonly rise as the accretion of bulk density. Apparent, because be in the stuff with bulk old density,this is, the union between solid photograph grain is mixed continuously quite firm, can maintain taller bulk stability consequently.
Zhengzhou flourish Cheng Naicai is located in Henan new close city, it is the company that a special production runs the product such as brick of heat insolation of compound to export carry out light qualitative heat preservation, the company is held to it is core with user demand, hold to " quality reachs the designated position, service " management concept, the accord that won a client in fireproof data industry is approbated and evaluate highly.
