Q:How long is the fire endurance of the rock wool board?
In the fire safety rules, of the building materials are classified as non-burning combustion body, difficult to burn the body and burning body categories depending on its difficulty level of burning. Rock wool board is the fiber processed by the coated steel sheet and basalt minerals and other inorganic minerals,and the building panels through artificial composition. Because that the dominant sectors, like, steel plate and rock wool are non-combustible materials, so it should be considered as non-combustible component. The fire resistance of rock wool board has its judging criteria. Loss of support capacity, loss of integrity and loss fire insulation function. Its fire resistance is within 2 hours.
Q:What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; Applications of ceramic fiber cloth: It can be applied to the thermal insulation of all kinds of furnaces, high-temperature pipelines and vessels; furnace doors, valves, flange seal, fire doors, fire resisting shutters and high-temperature furnace door curtains; engine and instrument insulation, clad material of fireproof cables, and high-temperature resistant and fire-proof materials; thermal insulation cloth for coverage, high-temperature expansion gap padding, and inner linings of the flue; high temperature resistant labor safety products, fireproof suits, high-temperature filtration and sound absorption, replacement of asbestos, etc.
Q:I wanna ask about the building insulation materials fire rating?
In China, the main external insulation materials are divided into level A, level B1, level B2 and level B3. According to the current "Combustion Performance Classification Method of Building Materials", level A thermal insulation material is incombustible material and inorganic insulation material. However, there are few level A thermal insulation material on the current market, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the organic insulation materials are popular in the market. Level B insulation material can be divided into three levels, level B1 is flame-retardant, level B2 is flammable, and level B3 is flammable. Level B1 nonflammable thermal insulation material is determined by the fire endurance of the material, in addition, different parts of material is divided differently! More common is EPS / XPS insulation boards which have added flame retardant through special treatment. B2 level of combustible insulation materials, common to EPS expanded polystyrene foam insulation board and XPS board, that is, we often say that the general board. The ignition point of this material is very low, and it will release a large amounts of harmful gases in the combustion process. level B3 flammable insulation material is a kind of thermal insulation material which mainly made of polyphenyl foamed. Since this material is highly flammable, it has been eliminated. Civil construction insulation materials, popular building insulation materials in China's current market are mainly made by three organic foam, such as EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane)
Q:What kinds of fireproof materials does the safe use?
Copper is one of the most widely used material in safe, for its good mechanical performance, corrosion resistance and processibility and it has beautiful color. Especially handles, locks and other decorations forged of copper are smooth, pore-free, also they have good density, and no blisters. They are solid and rust-proof, which can get gilded with 24K gold or gulch-gold and have other surface treatments. A lot of colors have been added to people's home for the copper's magnificence and nobleness.
Q:What is refractory material?
Q:Procedures for producing common refractory materials?
The general procedures of producing refractory materials include calcination of raw materials, selection of raw material , crushing, grinding, screening, mixing, ageing mixture, molding, drying, burning and etc. At present, the refractory factory usually purchases the calcined clinker, so the calcination of raw material is no longer a consideration of common refractory plants.
Q:What are Grade-A waterproof inorganic thermal insulation materials?
There is a market confusion in Grade-A waterproof inorganic thermal insulation materials. The products mainly include Grade-A monomer material like roc wool and ultra-thin insulation board and Grade-A composite material. Many Grade-B materials wraaped with calcium silicate board or foam cement belongs to Grade-A material, such as phenolic aldehyde composite. Some foamed materials with filling also belongs to Grade-A material. However, there are few products with Grade-A qualification. Many manufacturers are working on the margins of the records with Grade-A fireproofing performance examining report. But this situation will not be too long.
Q:What is the criterion of entry of refractory clay industry?
Refractory clay refers to clay which has a refractoriness of more than 1580 ℃ and can be used as refractory material and bauxite which used as refractory material . In addition to a higher refractoriness, they can keep the stability of volume under high temperature conditions and have slag resistance and thermal shock resistance and mechanical strength, so they are extremely firm after calcination.
Q:What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
They are not the same. If you say the ceramic fibers, they have some common points because the ceramic fiber is one of the refractory. It is belonged to the lightweight refractory which can be considered a new type of refractory with the main ingredient of aluminum silicate (including aluminium oxide and silicon dioxide).
Q:Are refractory materials and fireproofing materials the same?
Refractories are generally used in the industry such as power plants, electric stove and industrial furnace. They include refractory bricks and insulation materials. Fireproof materials are generally used in building and they are fireproofing.
