Q:What are the characteristics of magnesium fireproof plate
Plate glass magnesium fire with high temperatures, flame retardant, sound absorption, shock-proof, pest control, anti-corrosion, non-toxic tasteless non-polluting, can be used directly on the painting, direct veneers, available gas nail directly on the tile, the surface has good coloring , high strength, resistance to bending toughness, nails, saw, can be sticky, easy decoration. It can also be made into thermal insulation materials with a variety of compround composite insulation plate.
Q:Who knows the refractoriness of high temperature lightweight firebricks?
The disadvantage of light refractory bricks is its poor thermal insulating ability and the advantage is its endurable heat resistance property. The temperature range and main features of thermal insulation refractory are as follows. Diatomite brick
Q:What are the requirements of the performances of brasque refractory?
Physical properties of refractory include structural properties, thermal properties, mechanical properties, usability and operation property. The selection of the brasque refractory must have the following characteristics: 1. properties of not distortion and not melting at sufficient temperatures 2. have the necessary structural strength at high temperatures and does not soften and deform 3. must keep stable volume at high temperatures and will notcrack caused by expansion and contraction 4. will not rapture and flake when temperature is drasticly changed or heated unevenly 5. resistant to chemical erosion of metallic solution, slag and furnace gas, etc.
Q:Who knows the highest temperature the high-temperature refractory coating can resist?
The temperature resistance degree of high temperature coating is different according to different coating types. The temperature resistance degree is vary from tens to thousands, magnesia brick: Greater than 2000 degrees dolomite brick: Greater than 2000 degrees casting corundum brick: Greater than 1990 degrees. The above data come from the network, for reference only.
Q:Which brand of AAA refractory is good?
Foshan Nanhai Yanbu Shuying fire-resistant insulation material is very good, and it is a professional company of the production and sale of refractories. Our company specializes in the production of refractory bricks, refractory bricks, refractory castable, refractory aggregate, refractory materials, bauxite, alumina bricks and to undertake the production of various common refractory bricks and non-sizing bricks. The Zhengzhou Fire High Temperature Materials Co., Ltd. is also a good company. It is a collection of R & D and production company. The company mainly produces refractories, refractory bricks, refractory castable, refractory aggregate, refractory materials, special refractory bricks.
Q:What are the types of steel refractory materials
The major category is classified as permanent layer, working lining. Specific varieties: Air permeable brick (corundum). steel ladle brick (magnesia or corundum), permanent layer castable (high alumina), reinforcing material for ladle bottom, repair material for the edge of tank and so on.
Q:What are the differences between thermal insulation material and refractory?
Just as its name implies, Thermal insulation means that it doesn't conduct heat instead it insulates heat inside, while refractory means resistance to high temperature and it will not be out of shape or damaged due to high temperature.
Q:Who knows what material is in the center of fireproof rolling curtain?
Material and the type high silica cloth as curtain, side rails, with galvanized steel in its end and stainless steel two kinds of materials with double curtain in the end I hope my answer can help to you
Q:how to classify the fireproofing material levels A1 A2 B1?
their classification is shown specifically in Fireproof  Specification of Building Interior Decoration Design GB 50222-95 appendix A, flammability,inflammability materials, flame retardency, noninflammability: combustion performance of A, B3, B2, B1 materials are divided into
Q:What are grades of refractory materials?
Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ - 1770 ℃, advanced refractories: 1770 ℃ - 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler, (ratio) Max: Min < 4: 1; Shaped ones: no more than two-entrant, (ratio) Max: Min < 6: 1 or having a acute angle of 50 - 70 °; The specific type :( ratio) Max: Min < 8: 1 or having no more than 4-entrants or having an acute angle of 30 - 50 °; and Special products: crucible, containers and tubes. 3, divided according to the method of manufacturing: burned products, non-burned products and unshaped refractories 4. divided according to the chemical properties: acidic refractory materials, neutral refractory materials and basic refractory materials.
