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:How to hang the suspended brick in the refractory masonry?
First you can fasten the girder and the suspended brick with screws, and then move them to the specified location by a crane. You can contact the refractory plant in Shanshan mountain, Ningxiang Countym, Hunan Province at 0731-7150098.
Q:What's the material of electrical fire prevention board?
Electrical fire prevention board uses the material of inorganic binders, which mainly includes water glass, gypsum, phosphate, and cement; refractory mineral fillers: alumina, asbestos powder, calcium carbonate, perlite, cornstarch and etc.; electrical fire prevention board is mainly aimed at fire protection 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. Hope my answer is helpful for you.
Q:How to do environmental impact assessment for refractory Co., Ltd.
Give you a list of data, you can refer to. List of required data for environmental impact assessment 1) name, type, specification and quantity of main process equipment. 2) the supply and consumption of raw and auxiliary materials (annual consumption and unit consumption of raw materials, ingredients, electricity, new water and recycled water). 3) public utilities: power supply system: need to build several substations? What is the size of the substation? Water supply system: fresh water consumption, circulating cooling water consumption, domestic water consumption, production water consumption, fire water consumption, respectively, how much? Heating system: if the project has a self heating system, the size of heating boilers, types, scale, fuel types, sources, annual consumption, the boiler's circulating water supply.
Q:what's the requirements of refractory for forge furnace?
. . . . . . . .
Q:hat kind of fire retardant materials are there
fire-retardant materials include phosphorus chlorine, bromine and antimony, aluminum, boron based flame retardant, nanometer magnesium hydroxide, high purity industrial grade magnesium hydroxide flame retardant, high purity industrial grade modified magnesium hydroxide flame retardant, composite flame retardant magnesium hydroxide, aluminum hydroxide flame retardant, modified aluminum hydroxide flame retardant, light magnesium-oxide, unsaturated resin flame retardant, silicone rubber flame retardant, polyamide flame retardant, PE flame retardant, PP Flame Retardant, PVC flame retardant, wood flame retardant, special flame retardant for paper, CPE flame retardant, fabric coating rubber flame retardant, flame retardant carpet adhesive, water based coating flame retardant, oily coating flame retardant, power coating flame retardant, ink flame retardant, and heat stabilizer.
Q:Which industry does the metallurgy and thermal insulating and refractory material belong to?
According to "New Economic Industrial Classification", the metallurgy and the thermal insulation refractory matter belong to C category. The manufacturing industry has 30 categories. The non-metallic mineral products industry has 303 classes. The production of building materials of tiles, stones, ect. refers to clay, ceramic tile production, building stone processing, building materials produced by wastes or drogs and subcategories 3035 produced by other building materials. The manufacture of thermal and acoustic insulation materials refers to the manufactuer of mineral insulation materials and other products, like rock wool, mineral cotton, expanded perlite and expanded vermiculite used for thermal insulation and sound insulation, but it does not include the production of 3039 subcategories, like asbestos thermal insulation and sound insulation materials, and other construction materials.
Q:How about the prospect of refractory material?
Cost reduction Refractory material is affiliated to base material factories such as steel, cement and glass. But the situation becoms more severe due to lmaterial reduction and waste. It is necessary to find a substitutional raw material.
Q:What are the refractory stocks?
The company produces energy saving, environmental protection type functional refractory materials and unshaped refractory materials. It is the main functional refractory material and unshaped refractory production enterprise in china. Company's products to new green high-quality refractory materials, energy saving and environmental protection as the leading iron and steel industry technological progress and improve the level of technology and equipment to adapt to meet the "development policy" refractories industry to develop industry, has a strong competitive advantage in the market. The main domestic refractory products company can only use part of the products of refractory materials production of iron and steel industry, iron and steel industry production and Pu resistant can be used in the vast majority of refractory products, iron and steel industry with the most complete refractory products. Therefore, the future development of the company is closely related to the prosperity of the iron and steel industry. More than more than 2000 enterprises in refractory industry, the company is the largest supplier of refractory materials in China, and the market share is less than 2%. Iron and steel group integration will inevitably lead to the overall contract cost control, supplier refractory decreases by seventy or eighty to two or three. The company's overall contract accounted for 37% (Montreal 68%), the overall contract increase will enhance the market share and profitability. China's urbanization, industrialization and investment in the 4 trillion infrastructure will stimulate sustained and rapid growth of China's steel demand. Therefore, in the long run, the prospects for the development of refractories for iron and steel are broad.
Q:how to classify Insulating Refractory ?
Low-temperature thermal insulation materials (less than 600 degrees Celsius): medium temperature thermal insulation materials such as diatomaceous earth, asbestos tile (600-1200 degrees C): high temperature thermal insulation material vermiculite, light clay bricks(greater than 12,000 degrees Celsius): Lightweight corundum brick raw materials: Clay, high aluminua, silica, magnesia
