Q:What's the feature of construction external wall fireproof and thermal inuslation matertial?
It has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Its heat conductivity coefficient at normal temperature is 0.018W / (K · m) . The thermal insulation property is three to eight times that of the traditional materials. And it is completely waterproof. [2] Thermal insulation lining has properties of low heat conductivity coefficient, low density, high flexibility, fireproof and waterproof. Light, generally about10-96kg / m3, 20kg / m3 or less is felt, 24-48kg / m3 is middle-hard plate, 48-96kg / m3 is hard plate, wherein 48kg / m³ can be used as ceiling, with softening point being 500 ° C , thermal insulation 300 ° C. It is widely used in the United States, k =0.9. Calcium silicate thermal insulation product is developed in 1970s in China. With high compressive strength, low heat conductivity coefficient, recycle and easily construction, it is widely used in the power system. In China, small workshop production were the most common, then four production lines were gradually introduced from America, including instant fiber forming, dry method punched felt, which are advanced and quality, temperature endurance up to 800-1250 ° C.
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
Q:Do you know the refractories?
Alkaline material products: MgO, CaO based crystalline phase, because MgO and CaO are alkaline earth oxides, so it is called alkaline refractory. Their high melting point, alkali resistance slag (C/S > 2) corrosion ability is strong, belong to advanced refractory materials, but they are easy to hydration. Magnesia chrome brick, dolomite brick, brick olive and other products, the main chemical composition is MgO, CaO China also belongs to alkaline materials.
Q:Can anyone tell me what is a high alumina refractory?
High alumina refractories: High-alumina refractory products have high refractoriness, compressive strength and refractoriness under load, which are used for building the high-temperature parts of various large blast furnaces, such steelmaking furnace, airheater, electric furnace, rotary kiln and other thermal equipment.
Q:What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?
Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)
Q:The effect of a high content of water in liquid resin exerted on refractory material?
For one thing, Substandard whiteness, transportation, low quality and the storage of refractory material may account for this. For another, a high content of moisture reduced the performance of refractory material. A high content of moisture is equal to buy water with same money in terms of trade settlement. Based on this, we can’t consider the super-standard water content from a single aspect, because the water content in refractory material is definitely super-standard, and another problem is particle size. Many people hold the idea that excessive amount of water content may revive its original performance, but it tends to have influenced the quality of refractory material.
Q:What kind of material is refractory fiber?
Refractory fiber, also known as ceramic fiber, is a fibrous thermal insulation refractory. It has the characteristics of ordinary fibers, such as softness, flexibility, having a certain tensile strength. And it can be further processed into a variety of products such as paper, wire, rope, tape, blankets and felts. Besides, it has high temperature resistance and corrosion resistance which ordinary fibers don't have. As a fire retardant and thermal insulated material, it has been widely used in metallurgy, chemical, machinery, building materials, shipbuilding, aviation, aerospace and other industrial sectors.
Q:what's the fire endurance of fireproof panel?
fire endurance of fireproof panel generally is 3 hours. For example, 12 mm non-asbestos fiber reinforced calcium silicate board, fireproof panel, two single 75 keel. through the monitoring of national fireproof construction materials quality supervision center, it's security and refractory time will reach over 3 hours. fireproof panel, also called fire resistance board, scientific name is thermosetting resin impregnated paper laminated wood,english abbreviation HPL(Decorative High - pressure Laminate) is fire resistant building material for surface decoration and has rich surface colors,lines and special logistics performance, it's widely used in interior decoration, furniture, cabinets, laboratory table, external wall, etc.
Q:Do you know what the main indicators are for the inspection of refractory materials? Thank you very much for your requests and reports
Fire resistance, combustion performance, combustion heat value, fire resistance, high temperature resistance, fire rating test and so on. Regular testing institutions are generally reported, Qingdao standard also can, the results are more accurate.
Q:Can the teflon material resist fire?
Teflon material does not burn, but the heat resistance temperature of it is about 300℃.
