Q:which kind of fire bulkhead is better?
General business fire endurance of two products are 3 hours. Organic fire bulkhead's main ingredient is organic material, which can be used in anti-corrosion and fireproofing cable tray. Inorganic fire bulkhead's main ingredient is inorganic material, which mianly play a role of fireproofing. It's main ingredient is inorganic material, so it can't be used in acidproof and alkali resistant projects. Of course, the price of same amount organic fire bulkhead in general is more expensive than the inorganic fire bulkhead.
Q:What kinds of refractory will be used in kiln of sintering ceramics?
High alumina brick, clay brick, insulating brick and silicon carbide plate.
Q:How much is the content of boron carbide in refractory material?
Is it available to iron materials?. Answer: It can be applied to all products, what you need is just a general proportion. Nevertheless, you’d better tell me what product it is exactly.
Q:Does refractory belong to stone, building materials or other?
It belongs to building materials.
Q:What's the function of aluminium dihydrogen phosphate on the refractories?
Mainly used for binder of high-temperature furnace refractory. Characteristics of liquid aluminum dihydrogen phosphate, castable. solid used for refractory spraying coating, chamotte, ceramic construction, which has high break resistance after being dried in 350-500 ° C, phosphate bricks. Characteristics of the solid aluminum dihydrogen phosphate, binding agent used for castable and casting industry: together with the refractory aggregate, ramming mixes at room temperature: Easy to mix, crush resistance, hydration resistance, chamotte, will not become soft even if soaked or boiling in water, molding. Liquid use refractory spraying coating, mainly used for corundum, chrome corundum water gap in refractory industry. The production of chrome aluminum zirconium corundum brick for water-coal-slurry gasifier is especially suitable for site construction applications mainly used for the electrical industry, high-temperature kiln and furnace, hardener, after mixing between 90-110 ° C for 4-24 hours at a constant temperature, forming strong bonding strength, electrical insulation, heat treatment resistance furnace
Q:what are the types of piping insulation material fire rating?
There are two grades: 1, the organic material: Grade B Grade B1 hard combustion (fire retardant) 2, inorganic materials: class A no burning it is divided into three levels, attributed to the types of materials!
Q:Which industry does refractory belong to?
It belongs to inorganic refractory: Ceramic refractory bricks (used in steel-making furnaces) There is also organic polymer in heavy industry: Halogen-containing and halogen-free It belongs to construction industry.
Q:What material is refractory material?
alumina refractory concrete, silica brick clay brick, metal ceramic, high temperature machine coating fiber reinforced ceramics, diatomite product, asbestos products, insulation board refractory. The definition of refractory can be searched in the website.
Q:What's the type of fire proofing thermal insulation materials?
Aluminum silicate: AlSiO3 With flint clay clinker as raw material, aluminum silicate is made by resistance or electric-arc furnace fusion and then spraying processing. Aluminum silicate fiber, also known as ceramic fiber, is a new lightweight refractory material featured by light weight, high temperature resistance, good thermal stability, low heat conduction rate, small heat capacity, good mechanical vibration resistance, small thermal expansion and good thermal insulation. It can be processed into aluminum silicate fiber board, aluminium silicate fiber felt, aluminium silicate fiber rope, aluminium silicate fiber blanket, etc. Featured by high temperature resistance, low heat conductivity coefficient, light weight, long life, good tensile strength and elasticity and no toxin, this new sealing material is an alternative of asbestos and widely used for thermal insulation of thermal energy equipment in metallurgy, electric power, machinery, chemical industry, etc.
Q:Who knows the model of fireproofing materials?
Models of fireproofing material: PC 6555 Bayer 6555 fireproofing PC 6557 Bayer 6557 fireproofing PC 6485 Bayer 6485 fireproofing PC 6385 Bayer 6385 fireproofing PC 6265 Bayer 6265 fireproofing PC 2865 Bayer 2865 fireproofing PC 4610 Dow 4610. Hope my answer will be helpful to you!
