Silicon Carbide

Product Description

Black Silicon Carbide is made by a precision water classification process and air flow classification using material that is produced from the reaction between high purity silica sand and petroleum coke in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.

Q:Does anyone knows which company produces the better refractory materials?: 1, Xinjiang Seekon new material limited liability company: Xishan Street No. 382,Saybagh District 2, Refractory Material Co., Ltd. In Xuyan, Benxi: Near the Sihu Road, Benxi City 3,Benxi Beitai new refractory material factory sales office address: Benxi city Sihu District Liu Toro No. 16

Q:Who knows about roof fireproofing materials?: Roof water proofing materials: synthetic polymer waterproof rolls, high polymer modified asphalt waterproof coiled material, sheet metal, synthetic polymer waterproof coating, one-component water curing polyurethane waterproof coating, penetration crystalline waterproof coating. Secondly, we have to choose materials that are suitable for roof water proofing. The right waterproof materials have better waterproof performance, TS-3B one-component water curing polyurethane waterproof coating is very suitable and the performance is good. Since traditional roof waterproofing materials have requirements on the moisture content of the formation level which should be less than 9%. It is really important to choose which materials to repair leaking roofs. Kitchens and toilets are moisture, the formation levels of buildings are hard to satisfy requirements, thus, waterproof?layer and formation level are easily get separated and are ineffective in waterproofing.

Q:What is the upper temperature limit for refractory materials?: The key depends on what refractories you use

Q:What is the fireproofing requirements of external wall thermal insulation materials?: According to the "building external wall insulation fire barrier zone technical regulations" to be published: it is not less than the level B2. But before the procedure was published, it should be strictly implemented the document, level A is the best, I hope to help you, hope to adopt

Q:Urgently!! Refractory problems, online, etc.: I feel that is the coating package, the coating of water is too large, the retaining wall in fused powder hydrated, can not produce strength under high temperature. What do you think?

Q:Who can tell me the properties and classification of insulating refractories?: The refractory materials refers to the refractory material of high porosity, low volume density, low thermal conductivity of the insulating material. Also called lightweight refractories. It includes insulating refractory products, refractory fiber and refractory fiber products.The characteristics of insulating refractory material is of high porosity, generally 40% to 85%; the volume density is low, generally less than 1.5g/cm3; the thermal conductivity is low, generally less than 1.0W (M - K). It is used as the insulation material of industrial furnace, furnace can reduce heat loss, save energy, and reduce thermal insulation equipment weight. The mechanical strength of refractory material, abrasion resistance and slag resistance is poor, should not be used for load-bearing structure of furnace slag, furnace, and direct contact with the molten metal and other parts.

Q:What are the commonly used fire protection materials: Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.

Q:Development trend of refractories: Mullite Matrix clinker. There are higher requirements of kaolin and refractory annded life, it should be able to grind medical industrial raw materials alumina, vacuum extrusion molding, high temperature roasting and smelting from unshaped refractory material a good thermal mechanical properties in the kiln and has good application prospect; 2, Dong Qingshi clinker. With kaolin and magnesia as raw materials, wet grinding, vacuum extrusion, and then high temperature calcination, furniture has a very good prospect; 3, magnesium calcium sand. Because of the development of clean steel, low carbon steel, high oxygen steel and stainless steel, the basic importance of free calcium oxide refractories is supported; 4, fused eutectic composite. Bauxite based fused corundum, bauxite based fused mullite, bauxite based fused mullite zirconia, fused corundum zirconia fused zirconia, Magnesium Oxide and other materials have been developing rapidly; 5, high density spherical hollow mullite aggregate. The wall thickness of the shell of the 0.2 - 1.5 - 5 mm, diameter 40 mm, smooth surface, can not be uniform, spherical shell, this may be a double, a prominent part of the surface can be dense, can also be used for hollow casting material, not only can improve the insulation performance of the material, in order to reduce the volume density. Instead of destroying its strength.

Q:What are the requirements for fire?rating of construction suspended ceiling material ?: According to No. 42 ducument of department of housing construction and Ministry of Public Security: fire?rating of building suspended ceiling material should reach A level. Other civil buildings: Class A fireproofing material MCM should be set in buildings whose height is above 50 meters. National A level fireproof flexible?material is made up of soil, rock flour, sand, cement and other inorganic powder and modifying agent. Product density is 2327kg / m3. Upon examination, the combustion performance of the product meets A level requirements, and the additional classification meets s2, d0, t0 requirements. According to GB 8624-2006 sepcification, combustion performance of the product should reach A2-s2, d0, t0 level. Light, thin: 2-4mm thick / piece, saving space and cement, convenient to transport. : State Class A fireproof flexible?material. Freezing-thaw resistance: up to 100 freezing-thaw experiments (close to 100 years), the surface has no powder, no crack and no peeling. Aging and acid resistance: anti-aging property can reach more than 3500h, that is, it will not degenerate for 50 years. Recyclable: new energy, renewable , no "three wastes" emission

Q:How many external wall thermal insulation fireproof material are there: Inorganic active wall thermal insulation materials, cement foam thermal insulation board, glazed hollow bead insulation mortar, rock wool plate, glass wool plate etc., if used for external wall thermal insulation, rock wool board more frequently used.
