Light simple fireproof stuff includes adiabatic and refractory products, fireproof fiber and fireproof fiber. By use temperature cent is: Microtherm heat insolation is fireproof material, use temperature under 900 ℃ , be like brick of diatomite heat insolation, expand silica goods, silicon calcareous plate, expand lukewarm heat insolation is fireproof in the; such as pearlite goods material, ℃ of use temperature 900~1200, if stick earthy and adiabatic firebrick, the heat insolation of; high temperature such as siliceous aluminous qualitative fireproof fiber is fireproof material, use temperature is more than 1200 ℃ , be like tall aluminous qualitative adiabatic firebrick, firebrick of alumina heat insolation, firebrick of silicon qualitative heat insolation, alumina is hollow ball brick, zirconia is hollow ball brick, tall aluminous fireproof fiber, much crystalloid is fireproof fiber (fiber of much brilliant alumina, fiber of much brilliant zirconia, qualitative fiber of much brilliant Mo Laishi) wait. In the electric stove body of heater that builds in build by laying bricks or stones, constant cent is fireproof layer, high temperature fireproof heat-insulation layer, medium lukewarm fireproof heat-insulation layer. To reduce boiler setting the accumulation of heat of itself is mixed through boiler setting the quantity of heat of outward be lost, when warming up in order to shorten, ask, managing heat energy, often standing by high temperature of electric stove liner ability of a thermal resistance is put near fireproof layer stronger, already fireproof the light simple fireproof stuff of heat preservation. Although this is planted,the bulk density of material has 0.4 ～ only 1.39 ／ Cm3, however ability the high temperature of 1200 ℃ above, be used as electric stove liner and material of high temperature heat-insulation layer widely. But also the bulk density as a result of it low, porosity is tall, cause mechanical strength difference of function of low, wear-resisting, fight chemistry caustic poorer also, intensity of machinery of high temperature of Lv of the take an examination when choosing whether contented requirement. 3 light simple fireproof stuff is commonly used kinds of craft that make hole are formed stomaticly is a crucial link in pledging fireproof material manufactures technology gently. Stomatic size, appearance, make an amount how many and the distributinging circumstance quality that affects product directly, the method that forms air hole is very much, pledge gently chemical method basically is used in production of fireproof data industry in our country, bubble law and combustible add a way. 1, law of chemical law chemistry is to point to a few material that can produce bleb through chemical reaction are added in preform. If join carbonate and instrument of acerbity, causticity and aluminium or metal and acid to wait, lend chemical reaction generation gas, make goods scores air hole. But because this kind of method reacts rapid, bleb makes not easy control, want to ask to join right amount depressor according to craft. 2, law of bubble law bubble is blowing agent is added in slop, be like soft black, through mechanical method processing generates bubble, as similar as chemical law, the bleb stability that bubble law produces is bad, want to add fixed agent control. 3, combustible joins law combustible to add a way is to show it is OK to be joined in slimy the material that burns, be like wood chip. These join content to be burned when high temperature of classics of light simple fireproof stuff is synthesized, generation is stomatic. But this method is having goods preform strength low, finished product is changeful the defect such as form, need control synthesizes craft to overcome. The main component that the application of light simple fireproof stuff pledges fireproof material regards kiln furnace, boiler, hot project as the equipment such as container gently, apply on industry very extensive. The fifties, regard the firepower power plant of fuel, rubbish as incinerator with coal or oil, boiler setting is the structure of heavy-duty brick system that be built with saggar brick and red brick build by laying bricks or stones and becomes 60 time of; , convert saggar brick and the; of structure of system of light qualitative brick that pledge adiabatic brick build by laying bricks or stones is built gently, fireproof material replaced indeterminate form generally boiler setting of bricky build by laying bricks or stones, form boiler setting of concrete of the posture that protect casing and boiler setting of concrete of the type that count a canal. Anyhow, because pledge fireproof material apparent pore leads tall characteristic gently, make its are in efficient and energy-saving, reduce hot loss respect to holding the position that cannot replace, but its goods apparent pore leads Gao Kang chemistry to erode function to differ, still cannot direct with burn makings contact. So far, light simple fireproof stuff is multi-purpose still the heat-insulation layer at high temperature equipment. Rise increasingly to the requirement of managing the sources of energy as the world, the research and development of light qualitative insulation material is one of insulation material that compare ideal domestic and internationally at present, it is good to have chemical stability, high temperature resistant, dimension precision is tall, the structure is even, the shell is beautiful, coefficient of thermal conductivity is low characteristic. Apply extensively at hot-blast stove now, vitreous crucible, metallic forge, kiln of channel of pottery and porcelain, kiln of type of electric porcelain shuttle, have wide market perspective. Fireproof material occurrence craze, fall off, easy how to wear away to do? Want to solve a problem thoroughly, need to be dug from germ, the analysis gives real reason, flourish Cheng Naicai is engaged in be able to bear or endure service of timber production, research and development is old, can solve all sorts of difficulty problems of liner of furnace of high temperature kiln, welcome broad new old friend to seek advice reach technical communication.
