Are brick of heat insolation of light qualitative heat preservation and light qualitative heat preservation pouring makings how to choose appropriate?

Is heat-insulating material of light qualitative heat preservation how adiabatic? If there is a large hole on fireproof material, convection can arise inside, if maintain difference in temperature small,heat radiation can cross; , heat is delivered can narrow. Ideal heat insolation is able to bear or endure material should have poriferous structure, stomatic Yue Xiaoyue is good. The data of low thermal conductivity is used between air hole, it is good that mural ply jumps over Bao Yue. Accordingly, at present the hole in the structure is the part with important brick. Assume poriferous body is comprised by small air hole, and cut off by Bao Bi as far as possible between air hole. Actually, through conducting the method length that increases heat to deliver, reduce thermal current of several minutes thereby, this is able to bear or endure namely the principle of adiabatic part job of material. The production methods of brick of heat insolation 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.
The sort that next light qualitative adiabatic firebrick introduce below and characteristic diatomite brick <1100 ℃ is made with natural and porous raw material, thermal conductance is small, heat proof quality pledges very gently argillaceous brick 1400 ℃ of 1200 ～ are multi-purpose can light legal system to build, utility pledges gently extensively tall aluminous brick law of 1350 ℃ bubble produces 1500 ～ , heat-resisting performance is good, use at high temperature heat insolation brick of light qualitative corundum 1800 ℃ of 1600 ～ Al203 content is high, advocate brilliant photograph is corundum, light qualitative silica brick can be used below reproducibility condition 1550 ℃ of 1220 ～ loading bate temperature is high, thermal stability good calcium is feldspathic light qualitative brick bases is 1300 ℃ of 1200 ～ CaO, al2O3, si02, bulk density is small, be able to bear or endure burst apart the gender is good, stable magnesium is qualitative in reducing atmosphere 1800 ℃ of 1600 ～ heat-resisting performance is good, stone of use temperature tall zirconium pledges law of 1500 ℃ bubble is produced, with Yu Chao zirconia of heat insolation of high temperature furnace pledges law of <2000 ℃ bubble is produced, with Yu Chao cordierite of heat insolation of high temperature furnace pledges <1300 ℃ heat expands small, be able to bear or endure flake function good carborundum pledges 1300 ℃ are able to bear or endure aggressivity is good, be able to bear or endure burst apart the gender is good, high temperature intensity   Light qualitative heat preservation is pouring expecting is one of series of numerous and fireproof material, the product of series of light qualitative heat preservation that flourish Cheng Naicai produces has bulk density small, coefficient of thermal conductivity low, quality light, compressive strength is tall, acid-proof the characteristic that corrodes with acid-proof sex gas, this product used material of high quality, high strenth to be aggregate, and exceed composition of fine pink, compound additive, the OK and very good hot heat energy that reduces industrial kiln furnace is used up, also can reduce lining weight at the same time. Use extensively at the industry such as furnace of electric power, petrifaction, metallurgy, kiln, the thermal insulation that makes fireproof liner and double deck liner and the adiabatic heat preservation of the similar device that heat up labour are pouring makings. Light qualitative heat preservation is pouring makings workability is good, felt force is powerful, time and construction coagulate to be able to operate time to grow first, intensity grows fast, impermeability strong, do not need acidification what make sure ash of body of build by laying bricks or stones is seamed easily is close-grained and processing, full, the anticorrosion ability of sex of the air-tightness that can raise chimney liner wall significantly, whole and liner, it is the good cementing material of flue of chimney stack, high temperature and air channel liner, the acid-proof project such as the acid-proof pool that also can be used at the industry such as metallurgy of oil, chemical industry, coloured, chamfer.
Are brick of heat insolation of light qualitative heat preservation and light qualitative heat preservation pouring makings how to choose appropriate? Join real case, which suit to choose which, this does not have destiny, important is the effect after wanting to assure construction. 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. Fireproof material chooses Rong Cheng, economic long life has assure. Liner maintenance chooses Rong Cheng, contractor bag makings is more durable!
