Q: What does fire-resistant insulation coating have?: Refractory thermal insulation material mainly refers to the inorganic thermal insulation material and composite thermal insulation material. According to the shape, it can be divided into: Finishing of fibrous shape, mineral?cotton, rock wool, glass wool, aluminum?silicate?wool, ceramic fiber, etc. Diatomaceous earth of microporous pile, calcium silicate, expanded perlite,expanded vermiculite,aerated concrete, etc. Foam glass of bubble shape, volcanic ash glass, foamed clay, foamed?concrete, gelatine powder polyphenyl granule heat insulating slurry of pasty form, etc. Their common feature is fire-retardant and firproof. It can be used in buildings with high requirements of fire?rating. Calcium silicate, aluminum silicate and asbestos can also be used for piping insulation of heat transport with high temperature. Hope it is helpful to you.

Q: The mechanism and function of antioxidants in carbon containing composite refractories are briefly described.: With the advantages of carbon refractories especially excellent slag resistance and high heat stability, but graphite under high temperature oxidation, in order to improve the oxidation resistance of carbon composite refractory materials, often adding a small amount of antioxidants, to improve the oxidation resistance of carbon composite refractories. Antioxidant additives commonly used in metal powder, silicon powder, magnesium powder, silicon carbide powder and so on.

Q: What is the difference in the nature between the refractory material and thermal?insulation?material: thermal?insulation?material is used to thermal insulation and the transfer of heat insulation. refractory material is defined as greater than 1580 ° non-metallic materials, such as calcium silicate board. its using temperature can reach to 1100 degrees, and some can also be used at high temperatures, and all high-temperature industrial can't be oprated without it, and the using temperature of polycrystalline alumina fibers can reach to 1800 degrees

Q: What's the definition of fire endurance of the fire-resistant coating for steel structure?: 1. Fire endurance. Conduct fire resistance test of any building component according to the standard time-temperature curve, and the time when it is subjected to the fire to the time when it loses support capability or fire insulation function or its integrality is destroyed is referred to fire endurance. 2. Steel has relatively low fire endurance which is usually 0.25h only, namely 15 minutes; 3. Of steel structure buildings, steel can be used as beams, pillars, etc. but its fire endurance is not enough (usually these components have higher requirement on fire endurance, and take pillar as an example, it is usually demanded that the fire endurance should be 2-3h), and under this condition, it needs to brush fire retardant coating so as to raise the fire endurance. As to the specific quantity or types of the fire retardant coating, it is decided upon the actual conditions. In short, the building material needs to meet the required fire endurance of the buildings.

Q: How much is the duration of fire resistance of the porous brick shale?: It depends on its formula since the highest temperature varies from formula. For example, the temperature of common bricks is 900℃, if the lime in it accounts for most part, then the temperature could reach 1050℃; if coal ash accounts for over 40%--50%, then the temperature could amount 1050℃--1150℃, I hope my answer will help you a lot.

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: who knows the fire resistant level of fireproof gypsum board ?: combustion performance of building decoration materials should be divided into four levels: A level, non-flammable; Class B1, flame retardant; B2 level, flammability; B3 level, flammable. Choose the materials above B1level. Thank you

Q: which kind of refractory is commonly used in the industry: Like silicon, magnesium calcium and metallurgy refractories, glass, silicon, etc., knowing the basic materials, and the businesses are not the same. I suggest that you can buy the refractory book to read.. Others include zircon, shapeless refractory material and so many other cement, such as magnesia, high alumina,ect.. Iron making is using the acidity material, continuous casting is using the clay, nonferrous metals and other types of more complex hot-press charcoal; steel making is using the alkaline, magnesium chrome, magnesium carbon, and clay,etc..

Q: Who knows the new fireproof and thermal inuslation matertial?: New fireproof and thermal inuslation matertial: foam concrete building blocks brick. The foam concrete building blocks brick is a new fireproof and thermal insulation material, with distinct advantages compared with the organic insulation material . Foam concrete can be used as wall materials, and it has a good self-insulation properties, so there is no problem of dropping off the outer insulating layer. A small part takes external wall exterior insulation, with mostly anchoring or dry hanging, which are not easy to fall off. Very few uses paste. Since the foam concrete and wall materials are of the same nature and strong adhesive, so it is also not easy to fall off.

Q: How can the furnace be replaced after the gasifier or water wall is replaced with refractory material?: If there is only a small local, bake according to the overall it is really troublesome, water wall repair point of direct drive estimation problem is not large, the water wall itself is used to slag slag slag principle, can also play the role of refractory materials.
