Q:Does anyone know which materials belong to light fire resistant material?
Building board of lightweight fireproof partition material: 1, GRC lightweight partition material glass fiber reinforced concrete; it is a kind of fiber cement composite with alkali-resistant glass fiber as reinforced material and cement mortar as the base material . Aerated concrete block equipment foundation construction Its outstanding features are having good tensile, rapture strength and good toughness. This kind of material is particularly suitable for the production of ornament mould and the manifestation of strong texture. Compared with these external wall decorative materials, the biggest advantage of GRC material is to meet the individual needs of architects, completing the expression of various ornament moulds and skin textures. 2, fiber reinforced low alkalinity cement building plate. The standards stipulate the classification, raw materials, technical requirements, test methods, inspection rules, packaging, labeling, transport and storage of the fiber reinforced low alkalinity cement building plate.
Q:Who knows about the types of Dalian thermal insulating and refractory materials?
There are many Dalian thermal insulation materials, which can be divided into organic and inorganic thermal insulation materials. Materials include inorganic thermal insulation materials, polyfoam, mineral wool products, foam glass, expanded perlite insulation products, gelatine powder EPS grain heat insulating slurry, sprayed mineral wool, thermal insulation product of foam cements, and vacuum thermal insulation board.
Q:I want to know what is the slim in the refractory bricks
Where are you from, I can introduce to you
Q:What kind of refractories do the anode baking furnace use?
5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
Q:What refractories are accessible with ease in daily life?
Basically there have all materials. But it depends on your needs.
Q:Are the specification of fireclay bricks and ordinary clay brick the same?
Do you want to know whether the specifications of fireclay bricks and ordinary clay brick are the same?
Q:What are the materials of insulation firebricks?
The raw materials of firebricks, firebricks have various raw materials, and the composition of which can be divided into six categories: soil, stone, sand, mineral, powder and others. One of the raw materials, soil: bauxite, kaoline, clay, diatomite Another raw material, stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, and silica Another raw material, sand: clay sand, zircon sand, quartz sand, and magnesite Another raw materials, mineral: chromium mineral Another raw material, powder: aluminum powder, micro-silica powder, and silicon powder Another raw materials, others: asphalt, graphite, phenolic resin, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica sol, boron carbide, calcium aluminate cement, nitride material, haydite, aluminum oxide, alumina sol and zirconia, etc.
Q:Urgently!! Refractory problems, online, etc.
Uneven contraction. When the magnesia block wall is made, the steel wire mesh can be added to the magnesium block wall. That will solve the problem.
Q:What's the maximum temperature that the refractory ceramic fiber cloth can endure?
Ceramic fiber cloth is high temperature resistant and its continous use temperature can be up to 1000℃. It has high temperature resistance, low heat conductivity, thermal shock resistance, low thermal capacity; superior insulating property at high temperature, long service life; resistance to nonferrous metals like molten aluminum and zinc erosion; low and high temperature strength; innocuity with no adverse effect on the environment; and it is easy to install.
Q:What are the refractories for converter?
Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,
