Q:Who can introduce the difference between galvanized fireproof coatings and steel structure fireproof materials?
There is no difference between them because they are the coating with the same texture. But generally galvanized treatment is not necessarily needed for brushing fireproof coating. Fireproof coating and galvanized surface have relatively poor bond strength. So it is advisable to bursh trasitional lacquer or micaceous iron on galvanized surface.
Q:What are included in fireproofing materials?
There are many types of fireproof materials, and the following listed below is the main species: All kinds of fire retardant coating such as finishing fire retardant paint, fire retardant coating components, fire-resistant coating for steel structure; all kinds of fire-proof materials such as fire retardant material and its products, textile, fire retardant fabric, building materials and products, flooring material and external wall thermal insulation system; all kinds of fireproofing components such as fireproof panel, fire door, fire resistant window frame, fire resisting shutter, fireproofing glass, elevator landing door,ventilating duct, fire-proof sealing material and fire protection smoke exhaust fan. The main indicators to judge fire resistance are: Flame retardency, ignition,production of toxic gases, smoke density,heat release and exhaust gas; fire resistance, combustion performance, heat of combustion, fire-resistant performance, high temperature resistance, fire rating, etc. There are some specific parameters which need to be judged by a professional testing equipment. You can go to the inorganic laboratory to check. The test results of fire rating are accurate.
Q:What is the magnesium carbon refractory?
The composition of refractory brick There are many types of raw materials of refractory brick, mainly divided into six categories: Soil, stone, sand, mineral, power and others. The first kind of raw material, soil: Aluminum soil, kaolin, clay, diatomaceous earth The second kind of raw material, Stone: Fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, silica The third kind of raw material, sand: Pottery, zircon sand, quartz sand, magnesite The fourth kind of raw material, ore: Chrome ore The fifth kind of raw material, powder: Aluminum powder, silica powder, silicon powder The sixth kind of raw material of refractory brick, others: Asphalt, graphite, phenolic resins, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica solution, boron carbide, calcium aluminate cement, nitride material, shale ceramisite, alumina, alumina sol and zirconia, etc.
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 !
From the perspective of appearances, grade A is 70mm, B 50mm. Their materials are the same .
Q:How to choose the material of refractory?
Long using temperature of aluminum oxide fiber is 1400 ℃, containing chromium aluminum silicate fiber, quartz, high purity aluminum silicate fiber, long-term use of temperature is 1000-1200 ℃ has aluminum silicate refractory fiber according to different raw materials, advanced refractory fiber (such as alumina. Commonly used vitreous aluminum silicate refractory fibre is amorphous, zirconium oxide refractory fibre) using temperature is 1700 ℃ view as >and the best temperature is 1300 ℃. Crystalline refractory fiber are polycrystalline mullite fiber, including ordinary aluminum silicate fiber, alumina and graphite refractory fiber, etc. The use of common refractory fiber temperature is 1150 ℃;>
Q:What is the difference between wear-resistant material and refractory material?
Focus is different. Some materials are called wear-resistant and refractory material. For example, refractory castable with high strength and wear-resistance, impressionable plastic material or brick. They all begin with fire-resistance and wear-resistance.
Q:what's the classification of fireproof materials?
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 Or the material itself has a high temperature resistance, heat-resistant, flame-retardant properties. Most of them are used for the construction industry.
Q:What's the fire retardant material of roller shutter fire resistance door ?
They are composited by inorganic materials, and the main components are perlite, inorganic adhesive and other special formula. It has flat and smoothe surface, unibody and stronger strength after molding. It has owned Chinese and Taiwan strength patent. It is fireproof, sound and thermal insulating. It has passed tests of Tianjin Fire Research Institute and Beijing construction institute. It is an ideal product.
Q:Who knows about the fire endurance of grade C fire doors?
The fire endurance of grade C fire doors is no less than 0.5 hours. As the key role of family fireproofing, fire doors is particularly important. It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. We can choose in accordance with different needs, but commonly used fire doors are grade A and B fire doors now.
Q:Who can tell me what is neutral refractory?
It is a material that can resist acidic and basic slag, flux and chemical erosion form other refractories at high temperatures. The main components include carbon, silicon carbide, aluminum oxide, chromium oxide and other trivalent oxides, such as carbon refractories and chrome refractories, etc. Strictly speaking, neutral refractories refer only to the carbonaceous refractories, including carbon brick and graphite silicon carbide products, etc. Sometimes, high alumina refractories with high Al2O3 content also belong to this material, such as some materials that are acidic but tend to be basic refractories, like sillimanite, mullite bricks and corundum bricks. Recently developed aluminum carbon bricks, zirconium carbon bricks alumina - silicon carbide - carbon bricks, silicon nitride bonded silicon carbide brick and so on are also neutral refractories. This material can be used in the bottom of blast furnace, the lining of hearth and bosh, and the lining of aluminum electrolytic cell, calcium carbide furnace, ferroalloy furnace, molten steel ladle, plating tank, reaction tank, and autoclave and so on.
