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: How to divide fire rating of decorating materials ?: level A: incombustible, B1: Flame retardant, Level B2: combustible, Level B3: Flammable.

Q: Is there vermiculite in refractory?: Vermiculite is usually used as lightweight material in refractory field, and its volume density is about 0.5.

Q: What are fireproofing materials?: Plants often use the fireproof sealing material with steel structures without much modification. All the panels that meet the first-order fire protection requirements can be fireproofing materials. Like gypsum boards, aluminum sheets and so on. . Coatings are usually those with fine powder, high density and good sealing. Hardeners mainly depends on specific requirements. .

Q: Does the refractory material used in steelmaking all refer to refractory brick?: It includes not only refractory brick but also unshaped refractory; while the foaming?agent, ladle filler sand and deoxidizer are not refractory materials but ferrous metallurgy auxiliary materials.

Q: Refractories for iron-making blast furnace?: Vibrating materials, corundum brick and aluminum carbon brick will be developed. Taphole commonly use stemming, silicon carbide - graphite bricks, whose material is Al2O3-SiC-C. Medium and large sized blast furnaces in China use dense mullite bricks, castable, graphite brick. Common lining material for iron ditch is ramming mass. hearth and furnace bottom common use carbon bricks, semi-graphite bricks, charring silica bricks, corundum bricks. Blast furnace bosh and lower part of furnace stack commonly use mullite bricks.

Q: what is the specs of thermal insulation refractory slab ?: thermal insulation refractory slab features wear proof, heat resistance, impact resistance, acid or alkali resistance, smoke resiatnce, fire proofing,fungi proofing, mould proof,anti-static. fireproof panel is generally used for countertops, tabletops, walls, cabinets, office furniture, wall hung cupboard. Common Specifications: 2135mm × 915mm, 2440mm × 915mm, 2440mm × 1220mm, thickness 0.6-1.2mm.

Q: Could you tell me the fire-resisting time of class B fire proof door?: The fire-resisting time of class B fire proof door is 1h and thickness of door can't be lower than 45mm.

Q: Is it normal for caable fire resistant material to catch on fire?: Abnormal; aging is certainly one of the cause of the fire. That is caused only because of poor insulation and aging caused by short circuit, but a more important reason is configuration of air switch does not meet the requirements. If the capacity of air switch equals that of the cable, trip will happen at the moment when current is overloaded, not causing a short circuit or over current fire.

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.
