As refractoriness

White Fused Alumina is the main starting material to produce high-grade unshaped and shaped refractoriness and is widely used in the field of iron-steel industry,ceramics,petrochemical industry etc. It is the ideal material to produce the unshaped refractoriness such as large ladle castables,medium and high grade BF trough castables,gunning material,pre-cast shapes and is the main material to produce alumina products such as corundum bricks, corundum and mullite-corundum sagger,refined porous plug bricks, monolithic lance composite nozzle, lining material for high temperature industrial furnaces,etc.

As abrasives

White Fused Alumina can be used as consolidation & coating abrasives, wet or dry sprayed grit, suitable for ultra-precise grinding and polishing in the crystal and electronic industry and can be used to produce high-grade refractoriness. It is suitable to machine high stiffness &high tensile strength materials such as chilled steel, alloyed steel, high-speed steel, high carbon steel, etc. In addition, it can be used as catalyst, insulator, precise foundry sand, etc.

Q:About the market issues of thermal insulation material and refractory material.
In fact, the thermal insulation material produced by the Sichuan-Benniao Hing construction company is very good, you can get the company's information just by inputing the Sichuan-Benniao Hing construction company into Baidu
Q:I would like to ask a friend that how much is the fire endurance of level A fireproofing glass?
fireproofing glass is mainly control the spread of fire or smoke insulation, and is a measurable fireproofing material, the fireproofing effect is evaluated by the fire resistance. It is through a special process and treatment, and it is a special glass which can maintain its integrity and thermal insulation in the specified fire resistance test. Original glass of fireproofing glass can be used float flat glass, and composite fireproofing glass also can use monolithic fireproofing glass.
Q:What refractories can withstand high temperature above 2100 degrees?
Usually a dryer will not have such a high temperature. I do not know what you would use it for. Refractory cement coupled with quartz sand can work for 4 to 5 hours. So you can try cement coupled with corundum or superfine bauxite for better effect.
Q:What's the material of fireproof and wear-resisting floor?
1. It is the kind of special concrete floor, and its production process is the same with that of the common concrete floor, but it uses different material which needs to be the pebbles and sand after processing with marbles and dolomite. 2. Fireproof floor is a kind of decorative material which is laid on the ground of the factory or large areas of floors. It does not support combustion or it is composed of flame retardant materials. Fireproof floor has two categories. One is composed of aggregate wear-resistant material which is solid particulate matter. Its construction method is to evenly spread aggregate wear-resistant particles on the surface layer of the concrete when the floor is just pouring concrete and solidified, and then a firm flame retardant layer will be formed on the surface layer. This is the the so-called carborundum wear-resisting floor. But this kind of material has many limitations and can only be used on the surface of the just poured concrete. In addition, it is easy to fade in color and not beautiful in appearance. So this is not fireproof floor in the strict sense. Here we focus on a new liquid coating fire protection floor, which is environment friendly, widely used and beautiful in appearance. 3. Wear-resistant floor has the characteristics of pressure resistance, strong wear resistance,oil resistance, and anti-infiltration. It is also dust-free and easy to clean. After entering the initial setting of concrete, construction can be started immediately. Construction period is usually longer, but better using effect will arise.
Q:Which kind of furnace hearth refractory is better?
Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
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:How to divide the fire resistant level of construction thermal insulation materials?
1, Combustion performance of the national standard building materials are divided into the following levels: Class A: incombustible building material: Material that almost never burn. Class B1: nonflammable building material: Nonflammable materials have good effect of flame resistance. In case of fire it in the air or at high temperature it is difficult to catch fire and spread, and when the fire source is removed, the combustion can stop immediately. Class B2: combustible building material: Combustible materials have good effect of flame resistance. In case of open fire in the air or at high temperature, it will immediately burst into flames and spread the fire quickly, such as wooden column, timber roof truss, wooden stairs, etc. Class B3: flammable building material: No flame-retardant effect, highly flammable, high risk of fire. 2, According to fire rating, external wall thermal insulation materials can be divided into 1) thermal insulation material with class A combustion performance. Rock wool, glass wool, foam glass, foamed ceramics, foam cement, hole-closed perlite,etc. 2) thermal insulation material with class B1 combustion performance: Extruded polystyrene board (XPS) after special treatment /polyurethane (PU) after special treatment , phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) thermal insulation material with class B2 combustion performance: Molding polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc.
Q:How to make fire resistant materials for building stoves
Legend of the old version has been upgraded, or can not enter the server, is not legend stopped?
Q:Which region use more refractory?
Places with steel mill, such as Hebei Province, Anshan City of Liaoning Province, south of Wuhan, Shanghai, all of these places have steel mills where use various types of refractories. In addition, architectural material industry, such as cement plant and glass plant all use refractories, but the variety is single, with a large amount.
Q:how long is the fire endurance of plasterboard?
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. In GB "gypsum board" it clearly states: Fireproof plasterboard can endure fire longer than 20minutes. Wherein Dragon brand fire-resistant gypsum board can endure fire longer than 40 mintues. Gypsum board is comprised of dry wall, steel stud and various auxiliary materials. the fireproof performance of the gypsum board system is relevant to the type, quality , layers of the gypsum board, quality of keel and installations, whether the rock wool is filled and its unit weight, the treatment of seaming and some minor joints.
