Q:How long is the fire endurance of the rock wool board?
In the fire safety rules, of the building materials are classified as non-burning combustion body, difficult to burn the body and burning body categories depending on its difficulty level of burning. Rock wool board is the fiber processed by the coated steel sheet and basalt minerals and other inorganic minerals,and the building panels through artificial composition. Because that the dominant sectors, like, steel plate and rock wool are non-combustible materials, so it should be considered as non-combustible component. The fire resistance of rock wool board has its judging criteria. Loss of support capacity, loss of integrity and loss fire insulation function. Its fire resistance is within 2 hours.
Q:How to divide fire resistant level of fire door?
The classification of fire resistant level of fire door: Grade A is not less than 1.2h. Grade B is not less than 0.9h. Grade C is not less than 0.6h. It is suitable for fire door with different levels: Grade A: Equipment room (such as fire-pump room,power distribution room, generator room, smoke control fan room, etc) door, fire compartment, door on firewall; Grade B: Eclosed staircase, front door of stair room, smoke-proof staircase and fire elevator share lobby door, front door of fire elevator, household door which directly opens to front room or shares room; Grade C: The vertical shaft door, such as strong electric wells, weak electric wells, pipe shaft door and air conditioning facilities. I hope this information can help you.
Q:What are the models of refractory cables?
There are bout four types. 1.NA-YJV / NB-YJV Crosslinked polyethylene insulated PVC sheath A (B) class fire-resistant power cable 2.NA-YJV22 / NB-YJV22 Crosslinked polyethylene insulated steel belt braiding PVC sheath A (B) class fire-resistant power cable 3.WDNA-YJY / WDNB-YJY Crosslinked polyethylene insulated polyolefin sheath A (B) class low smoke no halogen fire retardant power cable 4.WDNA-YJY23 / WDNB-YJY23 Crosslinked polyethylene insulated steel belt braiding polyolefin sheath A (B) class low smoke no halogen fire retardant power cable
Q:What's the heat conductivity coefficient of fire-resistant material?
There are many types of fire-resistant materials woth different thermal conductivity. The question should be more specific.
Q:Who knows the setting requirements of roofing fire barrier zone?
curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier between two windows, window sill wall and skirt wall should be sealed by the fire-proof sealing material at each floor. I hope I can help you!
Q:Using what kind of melting aluminium furnace refractories is more appropriate?
If it's the ordinary, you can use high aluminum refractory brick with general clay, GB/T 3994-2005 clay heat insulation refractory brick. If you need these with good material, there is high alumina thermal insulation refractory brick, GB/T 3995-2006 high aluminum heat insulation refractory brick, models have A13 and material is the alumina, A13 50 u, high insulating brick B5.Intermediate insulating brick B2, etc. Dolomite brick: good hang kiln performance, good erosion resistance, but brick is usually without f - CaO, hydration, and difficult to transport and storage, less used in the production. Magnesia-chrome bricks: good hang kiln, used in calcining zone. The disadvantage is that its thermal shock resistance is poor and plus hexavalent Cr is toxic, the production and use of magnesite chrome bricks in international countries gradually reduce. Now unit using the brick find replacements as soon as possible.
Q:What defect does fused cast refractories have ?
In glass production, in addition to refractory as a building material and consider its durability, we still must attach great importance to its influence on glass quality. In such cases, the impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement. What may directly affect the quality of glass are the wall brick and brick kiln bottom.
Q:How to choose thermal insulation materials for flood heating?
How to choose the appropriate thermal insulation materials: 1, Thermal insulation material shall have a small thermal conductivity, good thermal insulation properties. Besides, that also depends on whether the specific temperature changes of in the insulation materials' working environment can ensure the material has good thermal insulation. 2, when purchasing, we must be make sure it is light, and loose enough. These heat insulating material can not only afford bracket, and can also increase the heat transfer performance of the heat insulation material. prevet water penetration. Waterproof function should be soild, even if it accidentally absorbs water, its thermal insulation function must be guaranteed. 3, None of the organic material should applied to production of insulation materials, Thermal insulation material containing organic matter may get rotten, mildewed, and cause other destructive . At the same time they should not contain flammable substances, in order to avoid the fire. I hope my answer can help you
Q:Which kind of furnace hearth refractory is better?
Coal is acidic medium, so the matched material should be acidic refractories oriented, like silica bricks. For example, the coking coke oven and carbon furnace made of carbon are in reducing atmosphere, so they use silica bricks which have low price and good high-temperature indicators. If the part has special requirements, you can then consider other refractory on request.
Q:What is the offer of fire proofing thermal insulation material?
1. Fire proofing thermal insulation material ceramic fiber paper aluminum silicate fiber blanket/aluminum oxide fiber insulation cotton insulation pipe 15 yuan 2. 1260 ceramic fiber cotton thermal insulation panel thermal insualtion aluminum silicate aluminium oxide fireproofing fibre board 20 yuan 3. non-asbestos high temperature resistant aluminum silicate fiber insulation cotton fire-resistant material ceramic fiber cotton blanket 28 yuan The above prices are from the Internet and for your reference only.
