Black SIC ball

Q: How to use fire-resistant soil?: It can live with water, not too sticky. Don't be too thin. It's best to put the stove in the inner wall.

Q: Does the external wall thermal insulation materials level b1 need the fire barrier zone?: Residential buildings should meet the following requirements: 1, The height of building is greater than or equal to 100m, the combustion performance of thermal insulation material should be level A. 2, The height of building is greater than or equal to 60m but less than 100m, the combustion performance of thermal insulation material should not be less than the level B2. When using the level B2 thermal insulation material, each layer should set a horizontal fire barrier zone. 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 thermal insulation material, each two-layer should set a horizontal fire barrier zone. 4, The height of building is less than 24m, the combustion performance of thermal insulation material should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone. According to this understanding, it can not be set.

Q: What's the texture of refractory for the hearth of reverberatory?furnace? ?: The long-term usage temperature of ceramic fiber is between 950-1260 degrees.

Q: How long can gypsum board endure fire?: General gypsum plaster board with a thickness of less than 12mm has a fire endurance which is less than half an hour. Scheme One of gypsum board partition system by using 75# series of lightgage steel joist: separation distance of keels keep 600mm in vertical direction. The thickness is greater than 0.5mm; gypsum board: it shoule be the board of double-sided and single-layer with the thickness of 12mm. Fire-resistant gypsum plaster board's fire-resistance limit: 1 hour. Sound insulation index: over 35 rwdb.

Q: How can refractory material of the electric furnace be used for longer.: Do not exceed the temperature, do not exceed the limits of use in order to achieve the best performance and the longest service life

Q: What kind of material is good for cabinet fireproof board: Cabinet fireproof plate can be classified into fiber cement fireproof board, metal fire proof board, mineral wool fireproof board, perlite fireproof board, all sorts of fire prevention board. Fiber cement fireproof board is a kind of ornament plate using siliceous or calcareous as main materials and combined with a certain proportion of fibre material; metal fireproof board is a kind of decorative plate made of aluminum plate, stainless steel plate, color steel plate and other metal materials as the main raw material and added by certain flame retardant materials. Mineral wool fireproof board is a decorative plate made of mineral wool and glass wool; perlite fireproof board is hollow fire proof plate made of low alkalinity cement as the main raw material, and supplemented by certain perlite with fireproof function as filling. Fiber cement fireproof board is a kind of new material increasingly gets popular with superior heat insulation, sound insulation performance, belonging to the A1 level fire materials 1, Suzhou total surplus purification A-grade fireproof rock wool colored steel rock wool board range of applications: Partition ceiling material: Rock wool reference price: On a square 58.00/2 meters, Huarui thermal insulation fireproof materials aluminum silicate refractory aluminium silicate A-grade fireproof heat insulation aluminium silicate plate temperature: 1000 core material: Reference price for aluminum silicate fiber cotton: $3500.00\ ton

Q: Does anyone know about the fire resistance period of thin fireproof coatings?: Outdoor thin steelwork fireproof coatings have a fire resistance of 2.0 hours, the thickness of coatings is between 4.5 to 5 mm, the standard amount is 5.5 to 6kg per square meter. Specific situations vary according to the thickness data provided by manufacturers . The fireproof coatings are applicable for the surface of combustible substrates, which can reduce the flammability of the surface being painted, and block the rapid spread of fire. They can be used to improve the fire resistance of the materials being painted. The fireproof coatings are coated on the substrate surfaces. They are also rustproof, waterproof, wearproof, heatproof and anticorrosive apart from flame retardant. They have good tenacity, stainability, adhesiveness, glossiness and fast-drying nature.

Q: How is the fire endurance of the fireproof paint?: Fireproof endurance. fire resistance test of certain building components showed by standard time temperature curve from starting of fire to lose the supporting capabilities or its integrity or fireproof property. The fire proof endurance is 5hours.

Q: what are the types of piping insulation material fire?rating?: according to China's national standard GB8624-97, the combustion performance of construction materials can be divided into several grades grade A: Incombustible building material: Almost no burning material. Class B1: nonflammable building material: nonflammable material has a good flame resistance effect. when it meet the open fire in the air or burnd at high temperature, it is difficult to spread quickly, and when the fire source is removed, the combustion stop immediately. Class B2: flammable building material: flammable material has a good flame resistance effect. when it meets open fire in the air or at high temperature, it will immediately burst into flames and easily cause fire spread, such as wooden column, timber roof truss, timber beam, and wooden stairs,ect.. Class B3: inflammable building material: No flame resisting effects, highly flammable, high fire risk. 2, external wall thermal insulation materials, in accordance with fire rating, can be divided into1) grade A combustion performance thermal insulation material: Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.

Q: About the use of horseshoe glass kiln refractories: the lower portion of advanced clay brick, the lower portion of magnesia-chrome brick arch - high-purity silica brick; flue - clay brick; breast wall--33 # fused zirconia corundum brick (with shrinkage); fused zirconia bottom --33 # fused zirconia corundum brick (with shrinkage); regenerative chamber- the upper part of sintered magnesia-chrome brick, cooling section 33 # electric?smelting no shrinkage fused zirconia corundum brick; the wall - the melting section 41 # no shrinkage fused zirconia corundum brick (including 41% of zirconium; the lattice- superstructure of high purity magnesia brick, the same below); small stove --33 # fused zirconia corundum brick (with shrinkage). It can be said that it is the maximum configuration, if the funds is limited it can be downshift appropriately.
