Excel in pledges heat preservation brick calls light qualitative clay the brick again gently, excel in pledges the quality of heat preservation brick basically watchs its heat performance gently, the thermal capacitance sex that basically includes it, heat is expansile wait with temperature conductibility. Brick of because this excel in is light qualitative heat preservation a how many money is the thermal capacitance sex that this problem includes it according to its heat function, hot expansile can have a difference with the answer such as temperature conductibility. The client can seek advice from excel in to manufacturer home according to oneself need brick of light qualitative heat preservation a how many money. Thermal capacitance sex is the quantity of heat that shows material temperature lifts 1000 ℃ place is absorbed, the thermal capacitance of brick of light qualitative clay affects what build by laying bricks or stones builds kiln furnace to heat directly with cooling rate; The heat of argillaceous brick is expansile it is the performance that material lifts along with temperature and bulk increases, it is not constant value, change along with temperature and change, heat expands closely related the structure of function and brick of light qualitative clay and intensity, the argillaceous brick with high intensity has inferior hot coefficient of expansion; Temperature conductibility is material heating or in cooling process, temperature to all round the rate that the space delivers, the hot conductibility of brick of light qualitative clay is taller, temperature transmission rate is rapidder, everywhere difference in temperature is smaller.
Content of Al2O3 of brick of light qualitative heat preservation is in excel in more commonly 40 ％ above, fe2O3 content is less than 2 ～ 2.5 ％ . The grog in burden is 65 ～ 85 ％ , combinative clay is 35 ～ 15 ％ . Mix the combines clay and mill grog that smash grind, make up half dry pug together with grain grog again, high pressure shapes, firing below about 1400 ℃ , performance is better, weak acidity is shown below high temperature. Excel in pledges firebrick of heat preservation heat insolation and general firebrick are compared gently, 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, fuel drops so that charge meets 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. Excel in pledges firebrick of heat preservation heat insolation applies to 900 ℃ ～ gently the temperature limits of 1650 ℃ . Zhengzhou flourish Cheng Naicai is 15 years of great quality (the production of standard of good quality = + cast-iron pipe accuses) , 36 working procedure are layer upon layer accuse. Advanced equipment, high-tech automation line is produced, reduce 30% production cost compared to the same period. Zhengzhou flourish Cheng Naicai regards professional fireproof material manufacturer as the home, have rigid quality management system, quality has assure, the price is reasonable. Welcome broad client incoming telegram to hang down ask.
