- Q: What are the standards of refractory concrete ?
- It can be divided into: 1. Ordinary refractory concrete Aggregates used include high alumina, clay, silica, basic materials (magnesite, chromite, dolomite, etc.) or special materials (carbon, silicon carbide, zircon, etc.). It can also use several combination of refractory material. 1. Thermal insulated refractory concrete It is mainly formulated with refractory light aggregates. The light aggregate used can be expanded perlite, vermiculite, ceramsite, porous chamotte, alumina hollow ball, etc. It can also be a combination of several refractory light aggregates or combination of the refractory aggregates. The aggluetination material used in refractory concrete can be high alumina cement, phosphate binders, water glass binder and clay, etc.
- Q: Does hardware construction materials contain refractory?
- refractory includes one kind of building materials. It is a special material and not commonly used.
- Q: what are the requirements of fireproofing material?
- answer: 1 fireproof materials are used in construction, in various forms and it has played an absolute role in modern fireproofing, common fireproofing materials include fireproof?panel, fire door, fireproofing glass, fire?retardant?coating, fireproof bag,etc. 2, fireproof?panel is the most common texture in the market. There are two common types: One is the high pressure decorating refractory slab, it's advantages are fireproofing,moisture-proof, wear-resistant, oil resistant, easy to clean, and it has various colors; another one is glass magnesium fireproof board, external layer is decoration materials, and inner layer is mineral magnesium fireproofing material, and it can endure 1500 degrees high temperature but has bad decoration. Installing fireproof suspended?ceiling in outlet channel of construction, stairwell and corridor can ensure safe evacuation of people and protect people from attacking of fire spreading in the disaster. 3, the production process of fire and moth proof wood: firstly, put general wooden materials into solution with calcium, aluminum and other cations, then soak it into solution with phosphate radical, silicate and other anions. Thus, the two ions will be carried out chemical reaction in the wood, forming a ceramic-like material, and intimately fill the voids of cells, so that the wood has the fireproofing and mothproof properties.
- Q: How to determine the fire resistance rating of the aluminium-plastic?panel?
- The fire resistance rating of the aluminium-plastic?panel is determined by two indicators, namely national compulsory standard of GB8624 "Building Materials Combustion Performance Grading Method ", and GB/T17748 "Aluminium-plastic?Composite Panel National Standard" . Classifications of combustion performance of building materials in our country are as follows: A class: Incombustible building materials; B1 class: Flame-retardant building materials; B2 class: combustible building material; B3 class: flammable building materials. The fire resistance rating of the aluminium-plastic composite panel shuld be no less than B1 class. 1. Detection indexes and requirements of fireproof aluminum-plastic composite panel (B1 class): (1) Conduct the test according to GB/T8625-88, the average leftover length of each test specimen should be more than 150mm, (any test piece should have leftover length), and the maximum average flue gas temperature of each test should be no more than 200 ℃; (2) Conduct the test according to GB/T8626-88, flame hight indicators.
- Q: Who know about the knowledge of acid refractory material? Please explain in detail.
- Abrasion resistance of fire resistance material depends on the material group and structural material. The abrasion resistance of dense single crystal materials depends on the hardness of mineral crystal. The higher the hardness, the more resistance the material is to abrasion. non mineral crystals with fine grain material has a high wear resistance. The abrasion resistance of materials is related to bulk density or porosity. Aluminium refractory material can resist a temperature as high as 700~900 degree within the elastic range. The higher the temperature, the lower the resistance. Abrasion resistance will be increased with elastic modulus as temperature increase. In many cases, refractory material will often cause a lot of harm due to mechanical abrasion.
- Q: What are the components of refractory clay?
- The major raw material are bauxite, magnesite, silica, etc. It is easy to combine, high temperature resistant, corrosion resistant and has other advantages. It can be applied for refractory bricks in a variety of masonry.
- Q: The manufacturing technique of refractory material
- The major components of alkaline refractory material include magnesium oxide and calcium oxide. The commonly used alkaline refractory material is magnesia bricks. The magnesia bricks with 80%～85% magnesium oxide has good resistance to basic slag and slag and higher refractoriness than clay bricks and silica bricks. It is mainly used in open hearth, oxygen blowing of converter, electric furnace and smelting non-ferrous metal equipment and other high temperature equipment. Refractory materials applied on special occasions include high temperature oxide refractory materials such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, etc., refractory compounds such as carbide, nitride, boride, silicide and sulfide, etc., and high temperature composite materials, including metal ceramics, high temperature inorganic coating and fiber reinforced ceramics, etc. Consult and find reference for efractory materials production equipment, go to http://hi.baidu.
- Q: Who knows the new fireproof and thermal inuslation matertial?
- Ceramic foam insulation board, XTP vacuum insulation panels and a variety of composite insulation panels, etc. Relatively speaking, the inorganic insulation board is a trend. In terms of the overall performance, the cost performance of the foam insulation board is higher. XTP has the best performance, but with a little trouble in construction. Because of the vacuum characteristics, transportation and installation process should be very careful.
- Q: Which fireproofing materials factory is the best in Xiangyang?
- Xiangyang Tianhua Fireproof Materials Co., Ltd. has a variety of products with complete specifications. The products include fireproof cable tray, fire resistant groove, fire-resistant shield, ATD-AB, organic fire-proof caulking, intumescent fireproof pillow, fire retardant module, cable refractory coating, ultra-thin fireproof coatings for steel structure and other products.

Xiangyang Weicheng Fireproof Materials Co., Ltd. is specialized in research and development of fire-fighting apparatus and fire retardant materials! It's main products: fireproof bag, asbeston, fireproofing mud, and other types of fireproofing materials.
- Q: What are the uses of refractory materials of glass furnace?
- What are the uses of refractory materials of glass furnace? The refractory materials of glass furnace have a good corrosion resistance to steel slag, but are poor in thermal shock resistance, and the deformation temperature of loading at high temperature is low. Magnesite chrome bricks which are made of chrome ore and magnesia In different proportions have a good thermal shock resistance. They are mainly used as crown bricks of basic open-hearth furnace. The refractory materials of glass furnace are mainly applied to open-hearth furnace, oxygen-blown converter, electric furnace, non-ferrous metal smelting as well as some high-temperature thermal equipments, and they can be used for reaction tanks and liners of autoclave.
