$Ceramic Fiber Tape Refractory Material$

Q:Refractory net: I think China's refractory industry does exist high yield and quality is not high.The main reason, I think, is the immaturity of the Chinese government and individuals. First of all, the government does not encourage basic research, resulting in the lack of innovation in the refractory industry; moreover, the company and enterprise take immediate interests as the most important and do not value long-term development; individual enterprises are eager for quick success and instant benefit. Users of domestic refractories, refractory products only to the price for the bid by standard of foreign products; regardless of price, quite a bit of the meaning of things.

Q:What's the fire endurance of A grade fireproof glass curtain wall?: An hour and a half, an hour, and half an hour. As a key step in the home fire prevention, fire door is particularly important. According to the fire endurance and heat insulation performance, it can be classified as follows: A class fire door with fire endurance of no less than 1.5h; B class fire door with fire endurance of no less than 1h; C class fire door with fire endurance of no less than 0.5h. We can choose according to different needs, while A class fire door and B class fire door are now commonly used. Fire door has great varieties, and the material it uses is also of wide range. It includes stainless steel fire doors, glass fire doors, steel fire doors, etc. The most important feature of fire door is its fire resistance period. The main difference between A class fire door and B class fire door lies in their fire endurance, of which the former is no less than 1.5h, while the latter is no less than 1h. Difference between A class fire door and B class fire door also lies in their fireproofing material. That is the thickness of the built-in fire prevention board, of which A class fire door is 52mm, while B class fire door is 46mm. Therefore A class fire door obtains longer fire resistance period than that of B class fire door and gains better fireproof performance. A class fire door and B class fire door also differ in the places they are used. A class fire door is generally used in important fire fighting access of machine rooms, warehouses and oil depots, etc. and flammable and explosive public places, while B class fire door is generally used in the ordinary fire fighting access of some ordinary buildings. But B class fire door is more widely used than A class fire door.

Q:Who knows what kind of fire protection material is better?: Characteristic of polyurethane rigid foam thermal insulation decorative composite board: (1) ultra high cost performance, increased property's selling point (high cost performance) new model of thermal insulation material, excellent thermal insulation properties, elegant decorative effect, 50 years of service life, reduce maintenance costs and social waste. (2) it overcomes defects of traditional insulation technology (to solve the freezing and thawing, veneer cracking and shedding) traditional benzene board, the phenomenon of freezing and thawing that is easily appear in plastic extruded sheet, paint finish is easy to crack; its veneer facing can easily fall off; thermal insulation materials and wall are poorly adhered, easy off the whole. There is a themal bridge in dry hanging wall. (the characteristics of polyurethane composite board)

Q:Why do magnesium oxide refractory bricks can be made into refractories?: Because the magnesium oxide, commonly known as magnesia, which is a basic oxide, with the common property of alkali oxides and belongs to the cementitious material . It is white or light yellow powder, odorless, tasteless, non-toxic and a typical of alkaline earth metal oxide, whose chemical formula is MgO. It is white powder, with melting point of 2852 ℃, boiling point of 3600 ℃ and relative density of 3.58 (25 ℃). The magnesium oxide that is soluble in acid and ammonium hydroxide solution has high insulation properity. After high temperature of above 1000 ℃ burning, it will transform into crystals, and when rising above 1500 ℃ , it will turn into dead-burned magnesium oxide (also known as the magnesia) or sintered magnesia. So the performance of magnesium oxide refractory bricks is good, and the fire resistance of it is very strong.

Q:how is the high-temperature flame-retardant fibre board?: high-temperature flame-retardant fibre board is good decorative material. Hope it helps you.

Q:As for fireproofing material rock wool and glass wool, which one is better?: Rock wool board and glass?wool?board are a kind of new construction thermal insulation material, it's widely applied in construction and has replaced traditional thermal insulation material to some degree. With the gradually deepening study of rock wool board, glass wool board, we can find that these insulation materials have advantages in many aspects but there are also many deficiencies, particularly there exists a lot of controversy about the impact on the human body. The production process of rock wool board and glass?wool?board usually includes: after melting in high temperature of rock or glass, inorganic fiber is produced by high-speed centrifugation equipment, and at the same time add binder,dust?laying?oil,silicone oil at certain proportion, then produce sheet material according to different requirements. It has good thermal insulation properties, mechanical?property, sound absorption characteristics, belong to incombustible?material and is cheap. In general, insulation, security and economy should not be contradictory, three aspects should be taken into account, balanced chosen and developed. Rock wool board and glass wool board and other such materials should be properly selected and applied to the appropriate structure, so that the choice of material will play their strengths and avoid their weaknesses.

Q:Concrete composition and function of magnesia bond used in refractory: Mainly high purity magnesia powder and silica fume, in accordance with the 4:1 ratio of the mixture, that is, we often use in the castable MgO-SiO2-H2O binding system! Compared with cement, the content of CaO is lower, the high temperature strength of the product is increased, and the slag corrosion resistance of the product is increased!

Q:Are the specification of fireclay bricks and ordinary clay brick the same?: The standard size of refractory bricks in our country is: 230mm × 114mm × 65mm; ordinary brick: 240 ×115 ×53, building blocks: (it is divided into blind hole and via) 240×390×190, 240×190×190, 240×90×190, 190×190×190, 190×390×190, 190×190×190, 190×90×190, 140×390×190, 140×190×190, 990×200×400, 0×390×190, 90×190×190, 90×90×190. Another is interlocked hollow block : 90×200×400，90×200×245，90×200×200，90×200×100，90×200×290，150×200×275，150×200×200，150×200×100，150×200×290.

Q:what are the types of piping insulation material fire?rating?: Pipe insulation material Fire rating: heat conductivity coefficient(at room temperature) 0.025 grade non-combustible Class A low temperature bending ≤ 5000 breaking elongation 5,000 specifications 5000 anti-bending?strength 5000 compressive?strength 5000 special brand of high use temperature -250 ~ 150 ℃ core material, phenolic foam, form, stratiform, shape,flake.
