Q:What's the fire endurance of hollow brick?
This question is really very simple. It is better no to exceed 1050℃, or it will be easily burnt. I think 980℃ is ok actually. Around 950℃, no more than 1100℃, or brick will be burnt and melted easily.
Q:Why the refractories should be waterproof and wetproof
The binding agent of many raw materials is water-soluble. It will be useless when meeting water.
Q:Could you tell me how does fire protection standard of decorative material is divided?
Level of fire prevention materials: A grade: non-combustibility building material, almost without burning materials. A1 level: non-combustible, no flame A2, non-combustible, to measure smoke, to be qualified. B1 level: flame retardant building materials: flame retardant materials has good flame retardant effect. It is uneasy to burn when encountering open fire in the air or under high temperature and is not easy to quickly spread, and when the fire source move, it will stop burning immediately. B2 level: combustibility building materials: combustibility materials has good flame retardant effect. It will immediately burst into flames when encountering open fire in the air or under high temperature. It easily leads to the spread of fire, such as timber, wooden frame, wooden beams and wooden stairs. B3 level: flammable building materials, without any flame retardant effect, easy to burn, and with a very high fire risk.
Q:What materials is silicious thermal insulation board made of?
Refractories that contain more than 93% of the monox are acidic refractory materials which include ordinary silica brick, high-density and high-purity silica brick, silica brick that contains chromium, fused quartz products, unburned brick and siliceous ramming materials. It has good softening temperature under a fixed load and can resist corrosion of acid slag, but will have chemical reaction with alkaline slag. Silicious refractory of industrial value mainly is crystalline quartz, such as α and β quartz, tridymite and cristobalite.
Q:Which industry does refractory belong to? Does it belong to construction industry?
I do not recognize all the answers. No matter what kind of refractory can be used in construction. Biulding syove or kiln is construction. So personally, it belongs to construction indusrty.
Q:What's the B grade fireproofing material?
Grade B: rubber and plastic, extrusion molding, polyphenyl, PEF. organics, extruded sheet, polyphenyl board, phenolic resin. Hairong modules (thermal insulating and fireproof material) can reach grade B1 in fireproof performance.
Q:How long is the fire endurance of Grade A fire resisting shutter
Based on national standards GB 14102-2005 specifications. It is specified in GB 14102-2005 provides that: The fire resisting shutter whose fire endurance is not less than 3h is AAA fire resisting shutter when the unexposed surface temperature rise is used as judging condition. Therefore, it is required that the fire endurance of Grade A fire resisting shutter is 3h.
Q:Who knows about the B-level fireproof insulation materials?
Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.
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 #......
Q:Is there a worker in (Jigang refractory plant)?
Ha ha, base should be rest, you won't give you money, Hugh or those money, endlessly is your dedication. Should be double cease, ah, how do you say four days?. In theory, it's five days off now, and the three day of that is from the chairman to every employee.
