- Q: what's the seal of fireproofing material?
- Organic fire-proof caulking is made by taking organic synthetic?resin as bond and compressing the components together after adding fireproofing agent, filler. The putty won't solidify after a long time usage and has good plasticity, can be sealed arbitrarily. This kind of putty is mainly applied in opening's fireproofing and sealing project of construction pipe and electric wire and cable, and it's used with ATD-AB and fire retardant bag together. ATD-AB is a kind of gray powder material, after mixed with water, it can be used for the opening sealing of electric wire and cable or fire resisting wall of wire tunnel. The fire proof blockage is non-toxic, and no smell, has good water resistance and oil resistance with simple construction methods. It's oxygen index is 100 and it belongs to incombustible?material. it's refractory time can reach 3 hours, or above or below. as for some projects for perpetual usage, WXY-II will save the project fee and make the project solid. A kind of fireproofing material that can automatically expand and foam and sealed by opening after injecting the foam into opening. Sealing strip is a product or flexibility coiled material mede by fireproofing material with certain geometry shape. Sealing gum is a kind of liquid fireproofing material that has a function of fireproofing and sealing. Fire retardant bag is soft and windable tape-shaped product made by fireproofing material, it is winded on the external surface of plastic pipe and fixed with steel belt or other proper methods, it's the expansion, squeezing and softening pipe after contacting with fire, opening left by burning or soften of seal plastic pipe. Fire retardant ring
- Q: Why can aluminium hydroxide not be used to make refractory material?
- Hope my answer is helpful to you. It decomposes and produces aluminium oxide and water after heating, chemical equation for the reaction is: 2Al(OH)3=△=Al2O3+3H2O. Aluminium hydroxide can't be directly used to make refractory material because aluminium hydroxide is not stable.
- Q: Does the production of refractory belong to advanced technology？
- Refractory is traditional ceramic material. We can only say that national development is relatively backward. If the refractory is counted as new material, then it still has huge development potential.
- Q: What is the concept of lightweight refractory material?
- Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
- Q: What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- It usually used to test lightweight refractory. Density can be divided into apparent density (usually called as density) and true density: apparent density includes blow hole inside the sample; Unit weight is using quality to divide volume of sample and specific weight is used to represent liquid.
- Q: What are refractory materials?
- Refractories can be divided to two categories based on the shape and three categories according to the chemical nature of acidity, neutralily and alkalinity. Alkaline refractory materials are magnesia-carbon brick, magnesia chrome brick, calcium magnesium brick and magnesia-chrome bricks. Neutural refractory mateial are high alumina brick, corundum brick and clay brick. Case-hardened refractory materials are castable, ramming mass, gunning mix, coated mix, dry vibration material, etc.
- Q: What's meaning of CN of fire-resistant material?
- The commonly used preparation methodsinclude shock compression, high-pressure pyrolysis, ion implantation, reactive sputtering, plasma chemical vapor deposition, electrochemicaldeposition, ion beam sputtering, , low-energy ion radiation, pulsed arc discharge,pulsed laser inducing, etc. But the compounding result of superhard materialis not ideal due to deposition of amorphous CN film, nanometer level sizedC3N4 crystalline grain set in the amorphous film and few large graincrystal.
- Q: What's the A grade fireproofing material?
- Main materials are steel, wood, steel and wood. Fire door is one of the measures for buildings fire separation, and it is generally installed at the firewalls, entrances and exits of stairwells or tube well openings, which is required to play the role of fire protection and smoke control. Fire door plays an important role in preventing the spread of smoke and fire and reducing damages, so it must be strictly required. Fire dooor is classified into three classes of A, B, C, and their fire insulation and fire integrity is greater than or equal to the following values: A class fire door: 1.5h; B class fire door: 1.0h; C class fire door: 0.5h. It is in accordance with the provisions of 4.5.1.2 Article in GB12955-2008 "New Standard of Fire Doors".
- Q: How do refractory materials apply into pyrophyllite?
- When it is sized, add some clinker and after calcination, aggregate will be finished. From: turn to help
- Q: What's the fire endurance of A grade fireproof glass curtain wall?
- According to the latest requirement, fire door has three types of FMA, FMB and FMC, of which A, B, C refer to the class. Take FMA as an example, it refers to A class fire door (namely thermal insulation fire door). The fire endurance of these three types all can be 0.5h, 1.0h, 1.5h, 2.0h or 3.0h, and the specific fire resistance time needs to be determined by the design. Generally the design drawing will make clear of it. As to A class fire door, its fire endurance is 1.5h.
