When fireproof material is choosing, choose cubage as far as possible the raw material with opposite little density, in order to decrease store hot, promote adiabatic heat preservation practical effect, reduce boiler setting quality, reduce cost can. Use Mo Laishi of —— of light simple fireproof stuff to get together more small range of products and tall aluminium get together small range of products, reach its to reach adiabatic heat preservation and fire prevention material new-styly at fireproof Molaishi of the whole body or ferric oxide hollow ball handicraft makes li of line, this can reduce management cost substantially.
Heat preservation of heat insolation of another namer of light simple fireproof stuff is fireproof material, it is this kind of hole leads tall, cubage opposite density is small, conduct heat the fireproof stuff with low coefficient. By cubage opposite density divides light qualitative brick (cubage is opposite density 0.4 ～ 1.3g/cm) and exceed light qualitative brick (<0.4g/cm) . By application spends minute of ultralow temperature insulation material (900 ℃ of 600 ～ ) , in lukewarm insulation material (1200 ℃ of 900 ～ ) with high temperature heat-insulating material (> 1200 ℃ ) . Pledge into boarding by handicraft appearance cent fireproof material and mud assemble light qualitative fireproof data gently. By material cent sticky earthy, tall aluminium is made, Molaishi qualitative, silicon is qualitative, fireproof Molaishi pledges and ferric oxide is hollow the ball is qualitative etc. Choose light simple fireproof stuff but managing like that hot effect of makings, promotion, reduce working temperature, alleviate boiler setting is suttle, improve laborer environment.
Applied is spent when be less than 600 ℃ , discharge flue for chimney normally, have individual action demand, must choose appliance to be able to bear or endure fully corrode sex and effect of adiabatic heat preservation, choose light qualitative acid-proof sex normally fireproof and pouring makings, medium qualitative adiabatic heat preservation is fireproof and pouring makings and acid-proof brick.
Applied is spent for 600 ～ when 900 ℃ , must use fireproof data or be insulation material of fire prevention material. This section is heat preservation of ultralow temperature heat insolation, can use fireproof material and the raw material that also can use adiabatic heat preservation namely. Can choose fiber of pottery and porcelain (cotton of siliceous aluminous heat preservation) handicraft, cyst of general galvanized iron skin is used outside. (fiber of pottery and porcelain can not get wet in the rain, otherwise practical effect can reduce adiabatic heat preservation substantially) . Also can choose clay brick of light qualitative heat preservation, medium qualitative adiabatic heat preservation is fireproof and pouring makings, light qualitative acid-proof sex is fireproof and pouring expect or be clay light qualitative adiabatic heat preservation is fireproof and pouring makings.
Applied is spent for 900 ～ 1200 degrees, namely can the raw material of fire prevention material and adiabatic heat preservation. Be like this job middle-level, can use brick of tall aluminous light qualitative heat preservation, tall aluminium to get together brick of light heat preservation, Molaishi gets together brick of heat preservation of product of series of JM-23 of brick of light heat preservation, light qualitative silica brick, tall aluminium pledges gently adiabatic heat preservation is fireproof and pouring makings, Molaishi is light
Qualitative adiabatic heat preservation is fireproof and pouring expect as working middle-level, if pure sex is adiabatic,heat preservation still can use fiber of pottery and porcelain (cotton of siliceous aluminous heat preservation) handicraft. With felt of fiber of pottery and porcelain cyst or it is cyst of blanket of fiber of pottery and porcelain hind, cyst of general galvanized iron skin is used outside. Be aimed at the area of bend, have wet blanket of kind of fiber of pottery and porcelain, can basis steel appearance cyst figuration, after waiting for blanket to do impetuous, mix steel pattern is same. Or be it is partition of calcareous plate of silicon of keel of hard light steel, adiabatic heat preservation is actual the effect is first-rate also. Bent housing one part, can make abnormity according to appearance.
Applied is spent for 1200 ℃ ～ when 1400 ℃ , choose fireproof material without fail. Can use Molaishi to get together product of series of JM-26 of brick of light heat preservation and Molaishi get together product of series of JM-28 of brick of light heat preservation.
When applied spends more than 1400 ℃ , choose fireproof material without fail. Can use range of products of fireproof Mo Laishi and ferric oxide hollow ball range of products.
