Black Silicon Carbide is brittle and sharp and has electrical and heat conductivity in some degree. Aplications : Black Silicon Carbide is suitable for make grinding wheels, cutting wheels, mounted wheels, oil stone, abrasive media, and also suitable for surface grinding, lapping or polishing. The abrasive products made of it are suitable for working on Cast Iron, Non-ferrous Metal, Rock, Leather, Rubber, Wood, Ceramic, etc. Black Silicon Carbide is also broadly used as high-grade refractory material and metallurgical additive.

Q:What are the differences between intensive refractory busway and other busways?: Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. Suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities.

Q:Does the aluminum silicate thermal insulation material fireproof?: With stable performance,long fiber length, strong tensile strength, strong seismic performance, low shot, light unit weight, low thermal conductivity, good insulation properties. it is not bad.

Q:The primary problem, does the gas permeable brick is fired refractory bricks(refractory) ?: gas permeable brick have two types:built-in type and external mounted type. the built-in gas permeable brick and the external mounted gas permeable brick are usually made by fire burning, and small part of bricks are made by the low temperature heat.

Q:Could you tell me how does fire protection standard of decorative material is divided?: Building materials can be divided into four levels according to combustion performance (non-combustible, flame retardant, flammable, flammable). According to the Code for Design on Building Fire Protection and Prevention (GBJ16-1987) (revised in 2001):, the fire risk of production or storage is divided into a, b, c, d, e classes. Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Combustion performance grade A of commonly used adornment material: granite, marble, terrazzo, cement products, concrete products, gypsum, lime products, clay products, glass, ceramic tile, Mosaic, steel and alloy. I hope my answer can help you.

Q:What does refractory mean?: Ordinary refractories are often used brick, semisilica brick, clay brick, high alumina brick, magnesia brick etc..Special materials often use AZS brick, corundum brick, magnesia chrome brick, silicon carbide, silicon nitride bonded silicon carbide, nitrides, silicides, sulfide, boride, carbide and other non oxide refractory materials; calcium oxide, chromium oxide, alumina, Magnesium Oxide, beryllium and other refractory materials. Often used insulation refractories are diatomite products, asbestos products, insulation panels and so onUnshaped refractory materials commonly used are fettling, refractory ramming material, refractory castable, refractory plastic material, refractory clay, refractory gunning, refractory cast material, fireproof coating, lightweight castable, mud etc..

Q:What's the requirements of fire-fighting criteria of heat insulating material?: Specific provisions go as the following article 8: roof grassroots adopted duration of fire resistance is the non-combustible component that shouldn't less than 1.00 h's. Its roof insulation materials should not be below B2; Otherwise, the combustion performance of insulating material should not be below the B1 level. Article 9: The junction of the roof and wall, the insulation layer around the opening part of roof should use the grade A thermal insulation material to set level fire-fighting belt that width is not less than 500 mm. Article 10: the roof waterproof membrane or flammable insulation layer should adopt incombustible material to cover.

Q:Who knows how to divide the building fire grade and fire resistance grade?: I hope to help you building fireproof rank division is one of the most basic measure in building fire safety technical measures, Building's fireproof rank is divided into class one, two, three, four according to China's architectural design specification. Fire-resistant capability of the highest level is the strongest; Fire resistance of four level of the weakest. The fire resistance level of a building depends on the combustion performance and fire resistance of the building components that comprise the building. The so-called building component refers to a series of basic components, such as wall, foundation, beam, column, floor, stair, ceiling and so on. The judgment condition of the fire resistance There are three conditions for components' fire resistance limit to be reached, namely, the fire resistance limit of the building component: Loss of support and integrity; loss of time to fire the role of the time; as long as any of these three conditions is met, it will reach its limit of fire. Hope my answer will help you.

Q:What are the fire endurance requirements of class A fire resistant door ?: Fire endurance of class A fire resistant door is 1.5h. According to the latest fire door requirements, in FMA FMB FMC three forms, A, B and C represent categories, such as FMA on behalf of Class A fire doors (ie thermal insulation fireproof door). Fire endurances of class A,B and C fire doors are 0.5 1.0 1.5 2.0 3.0. Therefore, the fire resistance of fire door needs to be designed and the design paper will make it clear in general.

Q:Who can tell me about the foundry refractory materials?: The classification of refractories commonly used in casting and smelting: refractory bricks: siliceous bricks, high alumina bricks, corundum bricks, magnesia bricks, magnesia-alumina bricks, magnesia-carbon bricks,etc. shapeless refractory materials: ramming?mass, castable refractory, refractory cement, silica sand, magnesite, etc.

Q:Who knows about ranking rules of fireproofing thermal insulation materials for exterior wall?: You can try the following way to give a brief introduction of the fire?rating classification of external wall thermal insulation materials. 1. the building materials are divided into following categories in terms of combustion performance according to the national standard of GB8624-97. A-level： Incombustible building material: materials almost don't burn. B1-level: nonflammable building material: these materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building material: combustible building materials can play a certain role in flame resistance. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden column, timber roof truss and timber beam as well as stairs. B3-level: Inflammable building material: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1). Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite, etc. 2). The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene board(XPS)/ specially-treated polyurethane(PU), phenolic aldehydegelatine powder polyphenyl granule,etc. 3). Insulation materials with B2-level combustion performance: molding polystyrene board(EPS), extruded polystyrene board(XPS), polyurethane(PU), polyethylene(PE), etc.
