Kiln furnace heat preservation is energy-saving can protect an environment already, also can reduce caloric waste, how to come true? Use light qualitative adiabatic and fireproof data, for example heat preservation brick, heat preservation is pouring cotton of makings, heat preservation is waited a moment, it is OK to need those who pass liner to transform a design to come implementation heat preservation is energy-saving. Light simple adiabatic and fireproof stuff is to point to porosity density of tall, bulk thermal conductance is low, low high temperature resistant material, weigh light qualitative fireproof insulation material again. Include 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. What does light qualitative adiabatic firebrick have? The firebrick of boarding lump heat insolation that pledges adiabatic firebrick fastens interior to have adiabatic property for poriferous structure gently, it is with the production of bricky form product and application among them extensive, reason calls light qualitative adiabatic firebrick again. Light qualitative adiabatic firebrick presses his to material pledges or make place undertake classify and naming with raw material normally. For example, pledge with clay, silicon and the light qualitative firebrick that waits for raw material to make character calls tall aluminium respectively brick of light qualitative clay, light qualitative silica brick and light qualitative tall aluminous brick. The production methods of brick of light qualitative heat preservation has commonly undermentioned a few kinds: ① becomes brick from cut of natural and poriferous light qualitative Yuan Yan directly; ② with natural or man-made is poriferous light simple stuff makes a brick for raw material; ③ joins the combustible of easy burn-up in pug, be like light ball of rice husk of sawdust, char, polystyrene; Or add sublimate substance, be like naphthalene, burn oneself out, poriferous structure is formed after volatilizing; ④ adds foaming agent in pug, be like colophony black, firing hind acquire poriferous structure; ⑤ adds carbonate, aluminium powder and hydrochloric acid in pug, reaction of chemistry of have the aid of gives off gas and form poriferous structure. Generally speaking, use ④ of ② ～ to plant the method is more. Adiabatic heat preservation is fireproof and pouring makings 1, pledge gently partly fireproof and pouring makings, bulk density is 1.0~1.8g/cm3; 2, pledge gently fireproof and pouring makings, bulk density is 0.4~1.0g/cm3; 3, super- pledge gently fireproof and pouring makings, bulk density is be less than 0.4g/cm3; Press use temperature classification: 1, microtherm is adiabatic (pledge gently) fireproof and pouring makings, use temperature is 600~900 ℃ ; 2, in lukewarm heat insolation (pledge gently) fireproof and pouring makings, use temperature is 900~1200 ℃ ; 3, high temperature is adiabatic (pledge gently) fireproof and pouring makings, use temperature is >1200 ℃ ; 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 14:30 2020-06-25 old friend seeks advice reach technical communication.
