Application of white fused alumina
Made of abrasive, suitable for grinding hardened alloy steel, high speed steel. Fine-grained flour is also used for precision casting.
- Q: What's the maximum temperature that the high-temperature resistant refractory ceramic fiber cotton can endure?
- It depends on what material the ceramic fiber gasket uses. It’s usually referred to high temperature gasket made from ceramic fiber paper. It is generally classified into normalized form and high alumina type, of which the former can resist the maximum temperature of 1260℃ and its continuous use temperature is 1000℃, and the latter can be used for a long period at the temperature of 1200℃. Nichrome wire, stainless steel wire and glass fiber are reinforced. Ceramic fiber coating cloth and slag cloth, sintering ceramic fiber cloth and ceramic fiber fumigation cloth) Characteristics of the ceramic fiber cloth: It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment.
- Q: Why the refractories should be waterproof and wetproof
- The binding agent of many raw materials is water-soluble. It will be useless when meeting water.
- Q: What are the qualifications of refractory industry?
- Certificate for production and sale is needed, just like the certificate for other products.
- Q: The following statement is correct: artificial corundum has a high melting point and can be used as a high grade refractory material. The main component is silica dioxide
- 1. corundum is the main component of alumina. 2. agate is the main component of silica. 3. is right. 4. glass is silicate. 5. solar cells are made from monocrystalline silicon. So 3.5 correct, choose D.
- Q: Who knows that among refractory materials, insulation boards from which refractory material industry is superior in quality?
- Using high temperature insulation material during casting process .In the molding, assembly the insulation?board on the ingot head or install heat insulation cap . There are three ways to install the molded steel insulation board and install insulation?board on at the head of the ingot, namely, clamping, nail fixation and mosaic technique.Compared with clay-based liner, the use of insulating board will improve high steel billet rate up to about 5% to 10%.
- Q: who knows the fire resistant level of fireproof gypsum board ?
- The most commonly used ceiling decoration materials rates B1, including gypsum board, fibrous plaster, cement particle board, mineral wool sound-absorbing panels, glass wool decorative acoustic?panel?absorber, perlite decorating acoustic board, nonflammable plywood, nonflamable medium density fiberboard, mineral wool decorative board, flame retardant wood, aluminum foil composites, flame retardant phenolic plywood, aluminum foil glass fiber reinforced plastic composite materials. The fire gypsum board fire rating can reach A. Of course, many of the suspended ceiling gypsum board of inferior quality rates below B1. plasterboard is non-flammable B1 level products. There are introductions in Fireproof Specification of National Standard Building Interior Decoration Design. plaster board mounted on steel stud can be used as A level decoration materials. in accordance with the national fire safety rules on fire durance of walls and ceilings and other components. we can not simply say whether a piece of gypsum board can meet the requirements.
- Q: Is there anyone who can explain how to grade the level of fire insulation board?
- The classification of fire proof level for thermal insulating material 1, Burning performance of building material can be classified into the following several grade according to national standard GB8624-97: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect.
- Q: what should be paid sttention when buying the refractory?
- solve the resources and the cost as much as possible. Accurate understanding and knowing the material temperature changes of various partsin order to choose the appropriate refractories. 4： 3, work performance, for example, take measures to ensure the overall life, and it is a very good buying principles: melting in high temperature metal erosion. These are the four major problems to consider when using refractory. You can choose low prices and low transportation costs of materials to meet the basic principles under the conditions described above. 2.carefully observe the material to prevent the desturction and reducing the costs. according to the structure of furnace, reasonable coordination of all parts of the material, fully take the advantages of material characteristics and strive to develop the recycle, to avoid the destruction of the materials.1. the working characteristics and the sport condition and analyze the reason of destroying the material, which can not only gurantee the product quality and reduce the expenses, get familiar with the chemical component and physics of the material.
- Q: What's meaning of CN of fire-resistant material?
- The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
- Q: Who knows the texture of fire-proof wooden door material?
- Steel door, wooden door or steel wooden door can be inset fireproof laminboard, such as rock wool, perlite. Perlite (fireproof doors filling material, fireproof doors raw material) using for fireproof door core is mainly used for the filling material of fireproof doors and security doors. Fire protection, thermal insulation, good sound insulation effects, and higher performance than aluminum?silicate?wool and rock wool. The combustion performance of perlite using for fireproof door core reaches class A non-combustion, which is new type of fireproof doors filling material with characteristics of low cost, good fireproof performance and excellent environmental protection performance. The advantages of fireproof door core perlite as fireproof door filling material: 1, Good fireproof performance, so it has a function of fire prevention. Environmental protection: all materials are environmentally friendly products. Pollution-free: the product is composed of glass fiber reinforced materials and inorganic binder. 2, with characteristics of non-flammable, non-explosive, water-resistant, oil-resistant, chemical erosion resistant, non-toxic and good mechanical strength, etc. The product can be used for mechanic processing like sawing, drilling, gouging, etc. High fire resistance, in the simulated combustion tests, it doesn't deform when the flame temperature reaching 800 degrees, has good fire retardant and fire-resistant properties. 3, product material is cheap, suitable for all kinds of fireproof materials. Perlite fireproof board is made by pressing the expanded perlite powder and high temperature fireproof adhesive through mould, suitable for the filling material of fireproof wooden door and fireproof steel door, which is the substitute products of aluminum?silicate?wool and rock wool. 4, has advantages of light volume-weight, high refractoriness, strong compressive strength, small thermal conductivity, non-flammable, non-toxic, tasteless, non-pollution, etc.
