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: A chemical problem with refractory materials: In chemistry, there is never absolute

Q: Who knows about the fire endurance of A grade fireproofing glass doors?: The fire endurance of A grade fireproofing glass doors should be no less than 3 hours. A grade fireproofing glass doors use common glass of 6 mm. The shock resistance of float glass is about less than 5 min, and that of toughened glass is about 15 to 30 min. Fireproofing glass is classified in accordance with fire rating, the fire endurance of which is usually from 30 to120min, and that of the most common fireproofing glass is 60 to 90min, but now the market is a mixed bag, the so-called fireproofing glass is generally fake ultra-strong tempered glass. Therefore, you should buy the genuine glass with formal certificates, or you will bring yourself great inconvenience, and even more serious consequences.

Q: What are some of the new refractories and what are their characteristics?: Alumina, a better refractory material, is a new type of ceramic refractory, the characteristics are unclear.

Q: What are the models of refractory cables?: The models of refractory cables: NH-KVV22 copper core flame-retardant PVC insulated and fire retardant control cables with steel belt sheath NH-KVVRP copper core flame-retardant PVC insulated and fire retardant shielding control cables with steel braiding sheath NH-KVVP2 copper core flame-retardant PVC insulated and fire retardant shielding control cables with sheath and steel belt wrapping NH-KVVRP2 copper core flame-retardant PVC insulated and fire retardant shielding soft control cables with sheath and steel belt wrapping NH-KFF copper core fluorine plastic insulated and fire retardant control cables with sheath NH -KFFR copper core fluorine plastic insulated and fire retardant soft control cables with sheath NH -KFFP copper core fluorine plastic insulated and fire retardant shielding control cables with sheath and copper wire braiding

Q: What is molten silicon? What refractoriness do refractories made by it have? What properties of using does it have?: Molten silicon can be called quartz glass, which shows an amorphous silicon state. It is a liquid fusion at above 1723 degree and is an ultra-cooling state at low temperatures. It is not generated in refractories, but generated in the matrix, showing liquid state at a high temperature capable of buffering the stress with somewhat binding properties. If quartz glass is used as refractory, its function are melrly these ones. (These are what I konw for reference only.)

Q: What is the classification standard of fireproofing material levels?: the following are the criteria: Currently fire materials levels mainly include:class A : incombustible building material,which almost doesn't burn. class A1: non-combustible, without open fire, class A2, non-combustible, it needs to measure the smoke and be qualified. class B1: nonflammable building material: nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. class B1: combustible?building?materials: combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. class B3: inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster. In addition, according to different standards, fire-proofing materials' grade partition is different: DIN4102: A1, A2, B1, B2, B3: EN13501-1 A1, A2, B, C, D, E, F

Q: Refractory factory grinding brick dust harmful to the body?: Inhalation of this dust can affect people's respiratory tract for a long time

Q: Which kind of refractory floor is easy to use? ?: Recommend: Yong Wei fireproof board Henan Yong Wei Anfang Co., Ltd., located in Qinbei industrial agglomeration area, Qinyang City, Henan Province, was founded in 1995. It strated from the initial one fire decorative plate production line. After years of development, it has become the biggest fireproof decorative board production base with 25 fireproof board production lines.

Q: Which brand of refractory fiber hard thermal insulation board is better?: Thermal insulation materials are divided into two types: porous material and heat reflecting material. The former uses the air void contained in the material to maintain thermal insulation itself for the heat conductivity coefficient of air or inert gas within the voids is low, such as foam material, fibers and other materials; the latter material has a high coefficient of reflection which can reflect the heat, such as gold, silver, nickel, aluminum foil or metallic coated polyester and polyimide thin films. Aerospace industry has strict requirement for the weight and volume of thermal insulation material, and it is often also required to has the properties of noise absorption, vibration attenuation, and anti-corrosion. Different aircrafts have different requirements for thermal insulation materials. Aircraft cabin and cockpit usually use foam, ultra-fine glass wool, high silica cotton to maintain thermal insulation. Earlier missile head uses phenolic foam plastic as thermal insulating material. With the application of polyurethane foam with good thermal endurance, the single insulating material has been developed to sandwich construction. A few millimeters foaming coating is coated on the skin outside the missile instrument bay, it is anti-corrosion coating at room temperature and when aerodynamic heating reach 200 ° C or more, it will generate foam evenly thus maintaining thermal insulation. Artificial earth satellite moves in an environment where the temperature varies from high to low, so it must use laminated thermal insulation material with high reflecting performance, which is usually made up of dozens of layers of aluminum film, aluminized polyester film, and aluminized polyimide film. In addition, the successful development of the surface thermal insulated tiles has solved the problem of thermal insulation of the space shuttle, it also marks a higher level of development of insulation materials.
