wafer Silicon Carbide for abrasive  

Specifications:

Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and sharp and heat conductivity in some degree. The abrasive made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc It is also broadly used as refractory material and metallurgical additive

Q:How long is the duration of fire resistance that fireproof window of level B can endure?
The duration of fire resistance: fireproof window of level A shall not be less than 1.5h, while level B shall not be less than 1.0h. The frame of both fire proof windows A and B are made of steel, and the glass, not less than 26mm, is composite insulation fireproof glass. Monolithic fireproof glass window is neither B fire proof window nor A fire proof window, but non insulated fire proof window.
Q:What are included in roof thermal insulation fireproofing material?
Aluminium foil, bubble, aluminium foil/air bubbles/fireproofing aluminium foil thermal insulation material, fireproofing bubble thermal insulation material, fire retardant thermal insulation material, thermal insulation construction materials, aluminum foil insulation material.
Q:How to understand qualitative and qualitative refractory materials?
Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
Q:what materials can make external wall fireproofing paint have the fireproofing effect
First, the width of fire barrier is greater than 30CM, and the thickness should be same to the thickness of insulation material. fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. the thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Cement foam insulation board is recommended to use as external insulation board materials, level A exterior wall cement foam insulation board is a new ultra-lightweight thermal insulation material, with the advantages of lightweight concrete and insulation performance, with characteristics of low production costs, simple process, easy to operate, small product density in 180250kg / m3, high strength, low water absorption and good insulation properties, thermal conductivity of 0.05 ~ 0.07W / m · K and level A non-combustible; it is suitable for external wall insulation and fire isolation belt, and can meet the urgent needs of the market of exterior thermal insulation. With the increase of the intensity of the building fireproofing, the products will become the leading products in building insulation market in the future.
Q:who knows the technology of fireproofing material?
1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
Q:who knows the uses of refratories?
Of course, the role of the refractory material is fireproof, generally used in large buildings. It can reduce casualties and economic losses caused by the fire. it also can be used on the chemical instruments. ! !
Q:What 's the highest temperature can magnesium plate glass resist ?
Glass magnesium plate is non combustible plate having good fire-resisitance quality. Flame will never burn continuously on it. It does not catch on fire when temperature reach 800 ℃, and will not be lit up at 1200 ℃. The plate, having high-quality keel partition system, is rated as the highest non-combustible level A1 with fire resistance being above 3 hours. It absorbs a lot of heat when fire is burning, delaying rise of ambient temperature.
Q:what is the material of fixed first rate fire resistant window?
Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.
Q:Fefractory of aluminium oxide.
It can be refined into castable refractory and refractory bricks, according to temperature rating. There are shaped refractory material and shapeless refractory material, and ceramic fiber. So it must be specific. There is a large range of refractory, which basically contains the aluminium oxide.
Q:who knows the fire endurance of fireproof coating?
fireproof coating of different thickness differs in its fire endurance. Let me intrduce you as follows: The amount of time of 0.5 hours refractory thickness 0.45mm 0.79kg / m21 hr 0.9 mm 1.5kg / m21.5 hour 1.4 mm 2.3kg / m22 hr 2.0 mm 3.3kg / m22.5 h 2.8 mm 4.6 kg / m2
