Q:Who knows what material is in the center of fireproof rolling curtain?
In fact, in general, the middle of fire roller shutter is fire prevention materials, filled with asbestos fire protection materials in the fire shutter door of the two layer of iron sheet. I hope my answer can help you
Q:What's the fire endurance of fire windows?
Fire endurance of fire doors and fire windows stipulated by the fire prevention norm: Fire endurance of A class fire door or fire window is 1.2h rather than 1.5h, and fire endurance of B class fire door or fire window is 0.9h rather than 1.0h. Fire prevention code doesn't explicitly state that the fire door has thermal insulation function, so it can definitely be interpreted that the fire door only has fire integrity. For the fire door without heat-shielding performance, at certain distance from the unexposed surface, it has strong thermal radiation and is easy to hurt people. For the A class thermal insulating fire door, its fire integrity is 0.1h shorter than that of the corresponding fire door stipulated in the specification, but its heat-shielding performance and integrality is improved. All in all, compared with the specification that the fire integrity of the A class fire door should be 0.6h, it has much more improved its performance.
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 material composition of the new fire-resistant coating?
New fire retardant coating materials are produced by non-toxic expanding materials and special process, with no pollution. Use natural bite when installing, without using the formaldehyde and other toxic glue. It consists of a variety of organic matters, so it adapts to the natural environment, with long time of fire-resistant; The fire-resistant time for new fire retardant module is up to 4 hours or more, three hours more than the standard prescribed by the state. It is composed by the specially formulated materials, with no flying smoke, good heat insulation effect, fast heat dissipation, scientific and rational design, easy using and no falling off and long period of effective.
Q:What types of steel are silicious quicksand and chromium quicksand used in respectively?
Chromium quicksand can be used in steel-making process that has longer refining time like LF, VD and RH, in stainless steel drainage and thin plate drainage agent. Silicious quicksand is used in short steel-making process, process that is less than 45 seconds or process without refining. You can consult Hua Heng for details or inspect it by yourself.
Q:Which basic refractory is better?
Zhengzhou Xindeyuan Refractories Co., Ltd.and Zhengzhou Rongsheng Kiln Refractories cO.,Ltd. Their basic refractories mainly refer to refractories with magnesium oxide and calcium oxide as main components what can resist errosion of basic slag, including magnesia bricks, magnesia-alumina bricks, magnesia-chrome bricks, dolomite bricka and so on(magnesia bricks), among which magnesia bricks is the most common. Magnesia brick containing more than 80% to 85% magnesium oxide, has good resistance to basic slag and iron slag, and higher refractoriness than clay and silica brick. It is mainly used for open-hearth furnace, oxygen-blown converter, electric furnace, ferrous metal smelting equipment and other high temperature equipments.
Q:which kind of fire bulkhead is better?
Fire bulkhead also known as non-combustible fire retardance board, and it's made by various incombustible material after the scientific pressing, and has good flame resisting properties, it's non-combustible time can reach over 3 hours, high mechanical strength,it has characteristics of non-explosive, water and oil resistance, good chemical corrosion resistance and non-toxic. As for the combustion test of YD-Ba-type inorganic fire bulkhead, it's best to be deformation under the flame temperature of 1000 ℃, the indicators comply requirements of GA161-1997, combustion performance reaches A level standards of GB8624(non-flammable). J fire bulkhead is mainly applicable to the fireproofing protection and fireproofing isolation of cables with all kinds of voltage classes laid on scaffold or bridge. It's widely used in cable project fireproofing and fire retardant in the places with crowded cables, such as various power plants, chemical companys, iron and steel smelting enterprises, mines,etc. It's also the best fireproofing and fire retardant materials of fireproofing and fire retardant projects in indoor decoration of public places, such as large shopping malls, hotels, guesthouses, sports hall, closed clothing market, light industrial markets, theaters and so on. Construction method: Fire bulkhead products can be cut by saw, according to the shape required to be made in the construction site, using steel brackets or expaned anchor bolt to fix it while assembling, steel brackets should be coated with fire-resistant coating for steel structure. You can also use various cable and fireproofing trays made of fire bulkhead, and used in the board gaps.
Q:What is the limit of fireproof rolling shutter?
Fire proof door can be divided into Serie A, B and C in terms of fire endurance limit, fire resisting limit are not should be less than 1.20h, 0.90h and 0.60h. Set firewall has difficult sites can use fire shutter fire partition separating, when the back fire surface temperature rise refractory limit determination conditions of fire shutter, the fire resistant limit not less than 3H; when employed does not include back fire surface temperature rise do fireproof limit determination conditions of fireproof rolling curtain, on both sides of the shutter should be set up a separate closed type automatic water spraying system protection, sprinkler system continuation of time should not be less than three hours.
Q:What are the fire resistance ratings of the glass partition?
Hello, friend. The glass partition system is composed entirely of metal structures, glass, color plate and other materials which also has fire resistance capacity. When the inner structure of the system is steel structure, the fire resistance of which is 30 mins, 60mins or even longer.
Q:What is the magnesium carbon refractory?
The composition of refractory brick raw material There are many types of refractory brick raw materials, mainly divided into six categories: Soil, stone, sand, mineral, power and others. One of the original material, soil: Aluminum, kaolin, clay, diatomaceous earth The second 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.
