Main application: Widely used in various industry furnaces as refractory linings, such as blast furnaces, hot alr stove, reheating furnaces, soaking pit, water-cooling pipe binder, trough covers, steel ladle covers, electric furnaces roofs ceramic kilns, cement kilns, boilers, high temperature klins in the fields of petrochemistry and chemistry etc.
Remark: All products can be reinforced by steel fiber.
FACTORY:
- 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: Do you know the refractories?
- The so-called main component refers to the first phase and the second phase component, and the content accounts for about 90% of the total chemical composition. The development of modern technology more and more number of refractory material ingredients, so the second phase, the third phase component, adjusting the second phase, the third phase composition can generate a new technology in the chemical composition of the first phase beyond the limitations of the classification, a classification method is the most commonly used.
- Q: How to determine the fire resistance rating of the aluminium-plastic?panel?
- Class A incombustible and thermal insulation material: inorganic active wall thermal insulation material, cement foam insulation board, glass bead thermal mortar, rock wool board, glass wool board, foam ceramics, etc. With many characteristics of low density, low thermal conductivity, high pressure bearing capacity, convenience of construction, economy and durability, A class incombustible material is widely used as thermal insulation material for heat pipelines, thermal equipment, other industrial pipe-line equipment and industrial buildings, and thermal insualtion and sound absorption material for the building envelop of industrial and civil buildings. Because of good thermal stability, it is more often used as fire-proof and protective coating material of the steel structure.
- Q: What's the classification of flameproof glass, the refractory time of fireproofing glass.
- Classify according to the structure, fireproof?performance and fire endurance of fireproofing glass. Classify according to the structure: Composite fireproofing glass (FFB) and monolithic fireproofing glass, classify according to fire resistance: thermal insulation fire-resistant glass(class A) and non-thermal insulation fire-resistant glass (class C);classify it into 5 levels according to fire endurance: 0.5 h, 1.00 h,1.50h, 2.00h, 3.00h.
- Q: What needs to be noted when choosing and using blast furnace fireproof materials? Who knows?
- there are different temperatures in various parts of the blast furnace, thus using different types of refractory.
- Q: What's the material of electrical fire prevention board?
- Industrial electrical fire prevention board is mainly aimed at fire protection and thermal insulation. Iron plate is electrically conductive with good thermal conductivity, which will cause the result that the equipment is not insulated and suffers larger superheating surface! ! ! !
- Q: What is the interior fireproof thermal insulation material?
- polystyrene foam board, glass fiber spraying, polyurethane foam, thermal insulation system of inorganic wall. Use "DY" inorganic active thermal insulation material, have small thermal conductivity, large heat storage coefficient, better strength and achieve better thermal insulation and energy-saving effect when used in wall . Wall should definitely not crack and hollow because of high temperature in summer. It doesn't crack and shed because it is influenced by stress during heat expansion and cold contraction in cold winter.
- Q: What is shapeless refractory with high performance?
- The popular ones are: Non-cement fine powder bonded castable is a functional refractory castable with nano material introduced.
- Q: What are fire resistant level standards of class A fire resistant door?
- Situations under which fire endurance should at least meet class A fire resistant door standard: In basement, the fire door for room where the stored combustibles average weight exceeds 30kg/㎡; in partition basement, the fire door for partition of room where the stored combustibles average weight exceeds 30kg/㎡; in high building, the fire door for equipment room of automatic fire extinguishing system, fan room and air-conditioner room; in boiler room, transformer?cabin, diesel?generator room(other dangerous rooms), the fire door in firewall. These places are special and need high security, so they need to meet the standard of class A fire resistant door. What is class A fire resistant door? New Standard for Fire Door GB12955-2008 provides that class A fire resistant door thermal insulation and refractory integrity should be no less than 1.5 hours. In other words, the key of fire door grade is the fire-resistant time. Class A fire resistant door size: class A fire resistant doors have many sizes, and can be customized according to the needs of customers. For example, the size of some fire doors of the diesel generator room is large, while the size of fire doors of basement storing combustibles is small. So the size of class A fire resistant door is also different. Usually Xinduo will take this into account, produce class A fire resistant door with various sizes and can customize according to customer requirements. Class A fire resistant door standard: as is mentioned above, for class A fire resistant door standard, the key is the fire resistant time, no less than 1.5 hours. In texture, class A fire resistant door standard is manifested in the firm joint, uniform distribution of solder joints and smooth surface coating. It has also set fireproof sealing strip which should be straight.
