Q:What is acid refractory material?
Corundum products containing more than 95% of alumina are a kind of high quality refractory materials with a wide range of uses. Chrome brick by using chromium oxide as the main component of the corrosion resistance of steel slag is good, but the poor heat shock resistance, high load low deformation temperature. Carbon refractories with carbon bricks, graphite and silicon carbide products, low coefficient of thermal expansion, high thermal conductivity, heat vibration performance, high strength, corrosion resistance to acid and salt, without wetting of the metal and slag, light. It is widely used as lining material of high temperature, and also used as lining of autoclave in petroleum and chemical industry. Basic refractories in Magnesium Oxide and calcium oxide as the main ingredient, commonly used is brick. Magnesium Oxide 80% to more than 85% containing magnesia brick, has good resistance to alkaline slag and slag, refractory clay brick and brick high ratio. Mainly used in open hearth furnace, oxygen converter, electric furnace, non-ferrous metal smelting equipment and high temperature equipment. High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.
Q:What kind of refractory decorative board has good quality?
Baby Rabbit has excellent refractory decorative board. It once won the Chinese famous brand, and was awarded iconic brand in plywood industry and the most influential integrated service providers of indoor decoration materials . Fireproof panel is made from body paper(titanium coated paper, kraft paper) in high temperature and pressure through impregnation technology of melamine and phenolic resin. Refractory door slab is made by sticking fireproof panel on base materials such as density board or chipboard.
Q:what's the requirements of refractory for forge furnace?
. . . . . . . .
Q:I am a manufacturer of refractory materials. I would like to receive some orders from abroad. I would like to know what foreign trade companies in Dalian place foreign orders abroad
You don't give a cent to this question, no one will answer it
Q:What is the requirement of refractory concrete for raw materials? What is the main principle of commercial mixing station?
Refractory concrete generally divided into three categories: lightweight concrete (used in insulation); refractory concrete (for refractory temperature requirements are not very high position, and can withstand a certain air scour); heavy refractory concrete (flow with higher requirements for refractory temperature parts, and can withstand a certain intensity). Mainly depends on the design temperature and the use of parts.
Q:What are the applications of refractory busway?
Is an ieal power supply equipment for modern large and medium-sized enterprises, high buildings, the introduced projects, experimental base and other places.
Q:Which industry does refractory belong to? Does it belong to construction industry?
I am engaged in construction. Refractory material does not necessarily belong to construction industry. Fire resistance is only a part of material performance. Indeed, there are many places requiring refractory accorded with fire resistant level.
Q:Can anyone tell me which materials are fire-proof high temperature resistant material?
Fireproof high temperature resistant materials such as: Quartz, tridymite, cristobalite, chalcedony, flint, opal, quartzite, White silica sand, diatomaceous earth, the silicon oxide (SiO2) contained in these siliceous materials is at least 90% . The silicon oxide in some pure raw material can be above 99 %. Siliceous materials are acidic in high-temperature chemokinesis. when existing metallic oxide or contact with metallic oxide, they will conduct chemical actions and conbine into fusible silicates. Therefore, if the siliceous raw material contains a small amount of metal oxide, its heat resistance will be seriously affected..
Q:What are the advantages and disadvantages of new external wall fireproof and thermal inuslation matertials?
Advantages: 1)Low requirements on the waterproof, weather resistance and other technical indicators. The dry wall and gypsum plastering mortar, etc. can meet the requirements and can be easily obtained; 2) The inner insulation material are separated by the floor, and construct within a height of only a storey , without erecting scaffold ; 3) In the hot summer and cold winter or hot summer and warm winter area, the inner insulation meets the requirements; 4) The glass beads overcome the shortcomings of expanded perlite, like, large amount water absorption, easy powdering, big volumetric shrinkage in the slurry mixing process, easily leading to post-insulation product performance degradation and hollowing, cracking, and also make up for the defects of polystyrene particles organic materials, like, flammable, poor fire performance, producing harmful gas at high temperatures and anti-aging, poor weather resistance, poor workability and large rebound in construction, ect. Disadvantages of external wall insulation : 1) Since the ring beam, slab and column structure would cause thermal bridges, leading a greater heat loss; 2) It is of low intensity, high water absorption, easy to shrink and crack. The insulation system is prone to cracking, leaking or loss and other common quality problems, especially it is easy to crack at the seams, thus being difficult to exsit as long as the building. 3) It is inconvenient for the users to redecorate and hang ornaments; 4) It takes up indoor used space;
Q:How to distinguish between class A fire resistant door and class B fire resistant door from appearance ? What are the differences between the two refractories? Thank you !
It is difficult to distinguish from appearance. Their fire endurance are also different. The filling refractories of grade A and Grade B fire resistance steel doors are all perlite. The only difference lies in the filler compaction density.
