Black Silicon Carbide 1-10mm 90%

It is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand and petroleum coke. The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond. Its mechancial intensity is greater than fused alumina, but is brittle and very sharp. The mineral has some electrical and heat conductivity. Black silicon carbide is typically used for machining or finishing cast iron ,non-ferrous metals, stone, leather, rubber, and other materials where sharp cutting characteristics are important. The mineral is also used widely as a refractory material or metallurgical additive. More detailed specifications can be supplied on your request.

Q: How to divide fire rating of decorating materials ?: I am very happy to answer this question for you. It can be divided into Level A: noninflammability; B1: difficult-flammability; B2: combustibility; B3: inflammability. I hope my answer is helpful to you, thank you.

Q: What is the principal part of silicious refractory material: Silicon nitride and aluminite powder as well as dextrin

Q: How many hours of the fire endurance time of the rock wool laminboard?: Limit is usually two hours. Pay attention to it please.

Q: How to choose thermal insulation materials for flood heating?: 1, Select the appropriate floor material suitable for radiant floor heating. The floor radiant heating system mainly transfer heat through the ground concrete and the ground material to the room. Therefore in the heating season the ground material will always be heated during heating season. Therefore, it is better to choose stone materials and compround floor plate insensitive to tenmperature change with good heat dissipation and functions. Currently, wood floor is not suitable for the ground radiant heating system. 2, choose the pipe with anti permeability performance. Plastic floor heating pipe itself has a certain air permeability, if oxygen penetrates in it is prone to oxygen erosion and system's mental device will be eroded, resulting in the risk of leakage. Therefore in order to ensure the reliable operation of the heating system, the selected pipe must have anti oxygen permeation performance, and meet the standard stipulated by the DIN4726 oxygen permeation quantity: and be less than 0.1mg\L.d at 40 C.

Q: Who knows how many kinds of fireproof insulation materials are there in the market?: The so-called A-level materials in fire insulation materials, namely, the WW non-combustible insulation materials, and the WW material s are A-level. Inorganic fireproof and thermal insulation materials can be used as wall insulation materials to replace red bricks, therefore, they, as thermal and cold insulation materials, can reduce the thickness of walls, and save energy, as well as expand applicable areas indirectly, decreased structure weight. They are very good.

Q: What's the type of fire proofing thermal insulation materials?: Aluminum silicate: AlSiO3 With flint clay clinker as raw material, aluminum silicate is made by resistance or electric-arc furnace fusion and then spraying processing. Aluminum silicate fiber, also known as ceramic fiber, is a new lightweight refractory material featured by light weight, high temperature resistance, good thermal stability, low heat conduction rate, small heat capacity, good mechanical vibration resistance, small thermal expansion and good thermal insulation. It can be processed into aluminum silicate fiber board, aluminium silicate fiber felt, aluminium silicate fiber rope, aluminium silicate fiber blanket, etc. Featured by high temperature resistance, low heat conductivity coefficient, light weight, long life, good tensile strength and elasticity and no toxin, this new sealing material is an alternative of asbestos and widely used for thermal insulation of thermal energy equipment in metallurgy, electric power, machinery, chemical industry, etc.

Q: Development trend of refractory industry: In the central provinces in Henan, Shanxi, Liaoning China main manufacturer of refractory material, which is the main origin of three China bauxite, magnesite and other refractory materials; refractories industry by the end of May 2009 more than 3236 enterprises; industry revenue reached 67 billion 52 million 540 thousand yuan, Henan Province, Liaoning, Shandong, Jiangsu, Hebei and other regions, and refractories industry in the development of better leading enterprises, such as blue and white, accessible, prco etc. at present, its sales in the industry in the proportion is still small, the largest sales is also inadequate in refractory industry in 4%. An enterprise should play a leading role in leading enterprises in the industry, and its turnover in the industry should be more than 15%. Obviously, at present the refractory industry in the leading enterprises do not have, and the refractory industry concentration needs to be improved, and the existing resources in the refractory industry integration, is undoubtedly the way this process effective and efficient.

Q: What are the material requirements of class A fire resistant door ?: What are the material requirements of class A fire resistant door ?

Q: What are the additives and recipes of refractory?: Water reducing agent is to evidently reduce mixing water content while keep the slamp value of refractory castable almost invariant, also known as fluid loss agent. Water reducing agent itself cannot have chemical reaction with material component or compose new chemical compound, but it just seemingly has physical and chemical reactions. The binding agent of refractory castable is calcium aluminate cement combined with clay and oxide micro powder. In commonly used water reducing agents, the inorganic includes sodium pyrophosphate (Na4P2O7), sodium tripolyphosphate (Na5P3O10), sodium hexametaphosphate [(NaPO3) 6], super sodium polyphosphate (Na2P4O11), sodium silicate (Na2O · nSiO2 · mH2O), and so on; the organic includes lignosulphonate water reducer (sodium lignosulphonate, calcium lignosulphonate); naphthalene water reducer (naphthalene sulfonate or naphthalene homologues with formaldehyde condensate): water soluble resin water reducing agent (sulfonated melamine formaldehyde resin, abbreviated as composite of melamine water reducer).

Q: What are the main materials in concrete fireproofing material?: fireproofing materials mainly consist of class A incombustible?material and class B1 nonflammable material. Class A incombustible?material: Granite, marble, terrazzo, cement products, concrete products, gypsum board, lime products, clay products, glass, tiles, mosaics, steel, aluminum, copper alloy; class B1 nonflammable material: Ceiling materials, dry wall, fibrous plaster.
