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 electrical fire protection materials?: Flame retardant organic resin: They can be classied into PVC, vinyl chloride, chlorinated rubber, epoxy resin emulsion, epoxy resin, phenolic resin, etc.. Fire retardant additive: Phosphorus and halogens, nitrogen organic compounds (chlorinated paraffin, tributyl phosphate (TBP) and polybrominated diphenyl ethers) and boron (boric acid, zinc borate, boric acid aluminum), antimony, aluminum, zirconium inorganic compounds.

Q: Urgent question: could you tell me that the export of refractory materials to Vietnam is to be packed in wooden cases and smoked?: Solid wood logs are necessary. If it is the type of smoke free material, it will not be necessary. You'd better confirm it with the port of destination. Vietnam has the requirement to smoke

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 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's the refractoriness and how to measure the refractoriness?: Bottom each side length is 8 mm and upper side length is 2 mm. Under a certain temperature-rising speed, when heating, refractory's resistance to high temperature from melting is called refractoriness. The properties of cross section into an equilateral triangle and height is 30 mm. When it bends down until the vertex and chassis contact temperature is the refractoriness of sample. It bends due to the influence of its weight. Make the will-measured material into standard pyrometric cone.

Q: What's the material of electrical fire prevention board?: Industrial electrical fire prevention board is usually made of flame-retardant fiberboard, and its main purpose is for fire prevention and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface!!!! So the material uses the flame-retardant fiberboard. Hope my answer is helpful for you.

Q: What are the specific steps of stirring the steel ladle castable?: Steps are as follows. 1 Compulsory mixer is used to stir the castable and bags, rope and other debris can not mix in the castable when stirred. 2, Castable should be unpacked on the scene. Stirred volume depends on the capacity of the mixer. Castable should be accurately measured and put into a blender. 3 The process of first dry mixing and then wet mixing is adopted. After the castable is added to the mixer, it is dryly mixed for 2 minutes, add about 5.2 to 5.5 percent of water and continue to add water while stirring. Water that is 80% of the total should be added, and then decide whether to continue to add or not depending on the consistence (noting that the water must be clean water and sewage can not be used). Then it is wetly mixed for 4 minutes and stirred for not less than 6 minutes at one time, until castable is even. In general, the bottom is slightly dry and the wall of the ladle is slightly dilute (the amount of water is only for reference). 4, The amount of water and mixing time should be controlled strictly when stirred to ensure that the needs of the consistency are met. If castable is too thin, it will seriously affect the quality of the material. The stirred volume, stirring time and water that is added should be consistent and they can not suddenly be thick or suddenly be thin. If the consistency does not meet the requirements, the castable should be put back to the mixer and stirred with appropriate water or dry materials. 5, It should be stirred evenly and casting should finish in 20 minutes, in order to avoid sclerosis, affecting structural strength of ladle lining 6, After each completion of construction, varieties of castable should be changed and the mixer should be cleaned 7, Stirring can stop in halfway. If the mixer breaks down and it can be repaired in a short time, some of the materials have to be removed before the machine is opened. If the machine can be repaired on time, castable refractory should all be removed.

Q: Who can introduce the external wall thermal insulation materials fire rating regulations?: External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set 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 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials 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.

Q: What is required to do refractory material?: Can you be more specific about what aspect?

Q: What's the A class fireproof and thermal inuslation matertial for external wall?: First, external wall thermal insulation material: 1. silicate insulation material; 2. glue powder polyphenyl granule; 3. cement cystosepiment with the use of steel wire gauze (polystyrere); 4. extruded sheet; Second, roofing materials: 1. xps extruded sheet; 2. EPS foam board; 3. perlite and perlite brick; 4. vermiculite and vermiculite brick; Third, materials for heating power and air conditioners: polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Fourth, steel structure material: polystyrene, extruded board, polyurethane board, glass cotton lap felt, etc.
