Thermal conductivity of Oven insulation board

High Density Oven Insulation Board

Q:Which are fire proofing thermal insulation materials?: Which are fire proofing thermal insulation materials? Which fire proofing thermal insulation materials are commonly seen?

Q:Which brand of thermal insulating refractory is good?: The most famous is the dragon, Morgan, Luyang, which are good at making ordinary thermal insulation materials and whose products are cheap but quality. Guangdong ALISON nanometer aerogel is more expensive. The heat conductivity coefficient is 0.018. It can work under 1000℃

Q:Who can introduce the difference between galvanized fireproof?coatings and steel structure fireproof materials?: There is no difference between them because they are the coating with the same texture. But generally galvanized treatment is not necessarily needed for brushing fireproof coating. Fireproof coating and galvanized surface have relatively poor bond strength. So it is advisable to bursh trasitional lacquer or micaceous iron on galvanized surface.

Q:Who knows the fire endurance of rock wool color plate?: Colored steel rock wool board is used for areas with high fireproofing requirements. Colored steel rock wool board belongs to class A according to "Fireproof? Specification of Building Interior Decoration?Design" whose lifetime can reach more than 15 years, operating temperature can up to about 700 ℃, maximum fireproofing time is 6 hours. And rock wool colored plate is environmentally friendly materials, which is is the preferred material in the construction industry .

Q:How long is the duration of fire resistance that fireproof window of level B can endure?: Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours

Q:What are the materials of insulation firebricks?: The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.

Q:How to distinguish the construction fire-proof material rating?: According to national standard GB8624-97,combustion performance of building materials are divided into the following levels: Class A: Incombustible building material: Material that almost never burn. Class B1: Nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: Combustible?building?material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: Flammable building material: No flame-retardant effect, highly flammable, high risk of fire. According to national standard, the fire?rating of PVC floor must be class B1.

Q:What is special refractories?: Long nozzle, slidding plate, tapping hole, stopper rods, and products that steel mills use

Q:Can anyone tell me which materials are fire-proof high temperature resistant material?: Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..
