When pledging firebrick brick and blaze contact fireproof thermal insulation to produce craft to produce brick of brick of light qualitative fireproof heat preservation and the fireproof thermal insulation that blaze contacts gently, commonly used and the method that the method is bleb law and burn down addition agent. In expecting for Xiang Ni, infiltrate gas, have two kinds of methods: 1, first with mechanical method to suspension infiltrate inside fluid air, make the bleb inside pug stable with stabilizing agent next; 2, add blowing agent to the middle of suspension fluid, this kind of reagent makes gas after interaction, gas makes pug builds poriferous structure, this is stabilized with stabilizing agent after poriferous structure. Want to save the empty bleb inside slop to reduce the exterior pulling force of suspension fluid, add blowing agent commonly for this. Join inside Xiang Ni makings a large number of can the blame plasticity stock of imbibe, for example clinker, or mix into enters the crystallization substance that contains water of many to hydrate, with respect to OK and stable bubble. To make slop fleeciness, add carbonic acid body and acid to the middle of suspension fluid kind aluminous perhaps, metallic etc reagent, lend its chemical reaction and send angry bubble. To achieve this kind of goal, what often use in abroad is dolomite is mixed vitriolic, think they are cheap industrial raw material. Use half water gesso and material of other water rigid to serve as stabilizing agent. The pug of heat preservation brick is in caky hind undertake fast and dry and firing. Firing goods repass machining, make its have the appearance of need and measure. Use hollow ball makes alumina pledge the making burden of firebrick brick and craft use alumina gently stone of line of small pink of pink of corundum of frit of hollow ball, report, A-Al203 small pink, SiO2, silicon and clay pink are raw material preparation have fight flake the alumina of function is hollow ball brick. Alumina is hollow the ball is light aggregate, assure since high temperature resistant function and the effect that reduce density; Corundum pink is inert filling; Silicon line stone is expander, reduce since firing systole and the function that improve heatproof shake sex; Alumina small pink, oxidation silicon small pink and clay pink are bond, firing temperature is dropped since, form Molaishi to be united in wedlock photograph, improve fireproof data high temperature resistant the action with heatproof shake function. The burden plan that presses set undertakes the brick expects making up making, via mixing practice, shape, after natural and dry 24h, mix via dry 24h of 110 ° C again of 1600 ° CX4h firing make adiabatic brick. Quantity of mix into of silicon line stone is 12% when, the function that controls an adiabatic brick is: CX2h of 1710 ° C, 1600 ° weighs temperature of bate of 26MPa of intensity of bulk density 1.48g/cm3, compression, loading the change that burn a line + 0.3% , heatproof shake sex (water-cooling of 1100 ° C) 17: What make heat-insulating material have the characteristic of light qualitative, excel in, high temperature resistant, heatproof shake. 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.
