$Dense Fused Alumina For Refractory$

Q: how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q: What kind of material is refractory fiber?: Refractory fiber, also known as ceramic fiber, is a fibrous thermal insulation refractory. Refractory fiber, also known as ceramic fiber, is a fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts. Besides, it has high temperature resistance and corrosion resistance which ordinary fibers don't have. As a fire retardant and thermal insulated material, it has been widely used in metallurgy, chemical, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.

Q: who knows the uses of refratories?: Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !

Q: How should refractory cement be used?: How to use refractory cement? How to use refractory cement? Thank you.

Q: What refractory material does cupola lining use?: Refractories for ehongtianlu, Yong, eajliao, najhuo cupola, refractory (refraetoriesfo:Cupola, furnace) masonry cupola and related parts. The utility model also discloses a heating furnace, which is a thermal equipment for melting pig iron in the casting industry and certain steel smelting plants. The working temperature of the guard is usually 1400 ~1 stone.. C.

Q: Which schools are the best schools in the world for learning knowledge about refractories?: Wish it helps you out.

Q: Which are roofing fireproofing material?: (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.

Q: What are the characteristics of clay refractory materials?: Clay refractory has excellent performance in anti fatigue. The fatigue strength of the general metal is 50% ~ 40 of the tensile strength, and some composite materials can be as high as 70 ~ 80%. The fatigue fracture of the composite is from the matrix, which is gradually extended to the interface between the fiber and the matrix. Therefore, the composite material has omen before destruction, and it can be checked and remedied. Fiber composite material also has good performance in anti vibration fatigue. The fatigue life of The helicopter rotor made of composite material is longer that made of metal. I hope my answer will help you!

Q: How many external wall thermal insulation fireproof material are there: External wall thermal insulation materials are generally divided by the burning grade, into class A, B grade. Grade A is non combustible material, grade B is combustible material. Class A which can be divided into thermal insulation mortar, bakelite plate, rock wool plate, foam cement plate etc.. Insulation mortar is relatively good, easy for construction, convenient, low cost, but its production process is too simple, so it is prone to fake. I recommend you to find a large manufacturing factory that posses complete procedure, for example, provincial production record, the provincial use record, municipal record, tset report at or above the provincial level, state fire proof report, design drawings of office building. product will not be safe if there is a lack of any of these documents. Burning level for henolic is uaually class B, but class A2 can be reached if a thin layer of mortar is applied on the suface,(A1 is the highest level of fire safety),intensity of phenolic is not high, finger pressing will leave a pit on it. if classified according to kilogram, raw material differs greatly every 10 kilogram. Rock wool is also classified by kilogram, general using 150kg wool. Rock wool are now comprounded with average strength. It will easily absorb water, having trouble applying paints. Foam cement strength is not high, easy to absorb water, It is not resistant to falling. It costs low, only used unless little profit can be made, Do not use it if worrying accidents would happen. These materials can be firstly burned, The palce the sample into water to see if it will dufuse at last. External wall should stand up to wind and rain. In terms of thermal insulation, they are almost the same, shows little differences on design thickness.

Q: What are the uses of refractory materials of glass furnace?: crown--high-purity silica bricks; wall--melting end 41# fused zirconia corundum bricks with no shrinkages(41% of zirconium, similarly hereinafter), cooling end 33# fused zirconia corundum bricks with no shrinkages; bottom--33# fused zirconia corundum bricks(with shrinkages); breastwork--33# fused zirconia corundum bricks(with shrinkages); port--33# fused zirconia corundum bricks(with shrinkages); regenerator chamber--the upper part is for magnesite-chrome bricks, the bottom part is for high-duty fireclay bricks; checker--the upper part is for high purity magnesia bricks, and the bottom part is for magnesite-chrome bricks; flue--clay bricks. This is the best configuration. If the funds are limited, the configuration can be lowered, for example, the wall will be changed to 38 #......
