Excel in pledges adiabatic brick fastens interior to have adiabatic property for poriferous structure gently finalize the design lump heat insolation is fireproof goods, it is with the production of bricky form product and application among them extensive, call brick of light qualitative clay again.
The production methods of light qualitative adiabatic brick has excel in commonly undermentioned a few kinds:
1, become 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, the combustible that joins easy burn-up in pug, be like light ball of rice husk of sawdust, carbonization, polystyrene; Or add sublimate substance, be like naphthalene, burn oneself out, poriferous structure is formed after volatilizing.
4, foaming agent is added in pug, be like colophony black, firing hind acquire poriferous structure.
5, phosphate, aluminium powder and saline vinegar are joined in pug, reaction of chemistry of have the aid of gives off gas and form poriferous structure.
Generally speaking, be in afore-mentioned in all sorts of production methods, with the 2nd, the 3rd, the fourth kind of method application is extensive. Excel in pledges adiabatic brick department points to the small qualitative refractory products that contains Al2O330%-46% gently, mix with argillaceous grog or light qualitative grog but model clay is main raw material. Burden and water mix make but model pug or slop, with extrusion or pouring shape, dry hind oxidize with 1250-1350 ℃ in atmosphere firing. Commonly used excel in pledges the bulk density of adiabatic brick is 0.75-1.20cm3 gently, compression intensity is 2.0-5.9Mpa, thermal conductance is 0.221-0.442W/(m.k)(1350 ℃ ) . Excel in pledges gently the use of adiabatic brick is extensive, basically use that in all sorts of industrial kiln furnace not to contact melt content and without the thermal insulation stuff that eats aeriform action, use temperature is 1200-1400 ℃ . The main source Henan that Zhengzhou flourish Cheng Naicai is located in domestic fireproof raw material and fireproof data products is new close, the company is founded at going up century 90 time, undertake with school of domestic authoritative metallurgy the technology cooperates all the year round, win multinomial country patent, develop the fireproof product of energy-saving environmental protection actively, it is fireproof material finalizes the design major of goods and adventitious goods produces manufacturer, if you have excel in the demand of light qualitative adiabatic brick, the welcome calls Zhengzhou flourish Cheng Naicai.
