Q:What are the raw materials of refractory concrete ?
Q:How to divide the materials according to the National Fireproofing Material Standard?
2,generally, the external wall thermal insulation materials is divided in accordance with fire rating: 1, the class A combustion performance of insulation materials : inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement, hole-closed perlite ect.. 2) class B1 combustion performance of thermal insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde, gelatine powder polyphenyl granule, etc. 3) combustion performance of class B2 insulation material: molding polystyrene board(EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. I hope it will be helpful for you
Q:What high-molecular polymers can be used as fire-resistant material binder?
Lignin is the least expensive.
Q:What material is used to make furnace pipe of refractory bricks?
Refractory brick is called refractory brick for short. It is a kind of refractory material fired by using refractory clay or other refractory materials. Faint yellow or brownish. It is mainly used in building smelting furnace and has resistance to high temperature 1,580 ℃ -1,770 ℃. Also known as refractory brick. It is refractory material with a certain shape and size. It can be divided into burnt brick, unburned brick, fused brick (fused cast brick), fire-resistant insulation brick according to preparation technics; It can be divided into standard brick, ordinary brick and special-shaped brick, etc according to shape and size. It can be used as high-temperature building material and structural material of building kiln and all kinds of thermal equipment. It can also withstand a variety of physical and chemical changes and mechanical action under high temperatures. For example, fireclay brick, high alumina brick, silica brick, magnesia brick, etc.
Q:For refractory, why is it necessary to store the first mixing materials for some time under proper moisture and temperature?
It is mainly to remove gas form chemical reactions in the pug, give full play to plasticity and binding properties of combined, and store unburned brick whose cememting agent is phosphoric acid or aluminium phosphate for some time under proper moisture and temperature. For example, to avoid the formed bricks in the initial stage of drying and firing form cracking due to hydration of calcium oxide. Mixing materials is to store the first mixing materials for some time under proper moisture and temperature in order to improve the evenness and moldability of pud, such as making the distribution of combined clay and water more even. The length of storing chiefly depends on the process requirements and the characteristics of blanks. For the producing pug of high temperature kiln furnitures, the storing time is longer. The function of storing mxing materials varies with different natures of blanks. For honeycomb ceramics, it is to fully digest calcium oxide in blanks. For storing magnesia brick blanks containing much calcium oxide, it should be stored for some time in proper humidity and temperature.
Q:Which industry does refractory belong to?
It belongs to construction industry.
Q:What are the features of construction class A fire resistant door ?
1, Save space and reduce cost. Feature of Nanjing Cathay Class A external wall thermal insulation materials : the thickness is between 60mm--180mm, so compared with the traditional block thickness, it saves architectural space greatly. At the same time, the weight is only 1/10 of that of the traditional wall, thus reducing coast in terms of architectural structure. 2, Fireproof and green. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: fire endurance under high temperature of 1000℃ is 4 hours, and non-combustible performance can reach state A level, without any toxic gas in full compliance with international environmental standards. 3, Waterproof. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: no slightest leakage when it is being used in containers for water without any waterproof finishing. It can be used in kitchens, bathrooms, basements and other wet areas. 4, Sound insulation. Features of Nanjing Cathay class A fireproof external wall thermal insulation materials: internal materials and EPS polystyrene foam granule have good properties of sound insulation and sound absorption. 90mm-thick wall can insulate 40dB sound, in line with national standard of sound insulation for residential building. 5, Thermal insulation. Features of Nanjing Cathay Class A fireproof external wall thermal insulation materials: main raw material is frezing resistant and thermal insulating material which is environmentally friendly and energy saving. With good effect of thermal insulation, it can keep indoor temperature at a constant level, so as to make the environment more comfortable.
Q:What are included in wall fireproofing material?
External wall thermal insulation materials are divided into A and B according to combustion level. Grade A is incombustible material, while grade B is combustible material. A few years ago, fires in CCTV building and Shenyang hotel resulted from grade B material. Currently grade A is usually used, and some are even cheaper than the grade B material. Grade A is roughly divided into insulation mortar, phenolic board, rock wool board, foam cement board, etc. Insulation mortar is quite good. It is easy and convenient to construct, has low cost, but the production is too simple and it is easy to fake. It is recommend to find a large manufacturer with complete formalities, such as provincial records of production, provincial records of use, city records, type test report at or above the provincial level, national fireproof report and design drawing collection of department of construction. Lack of any is unsafe. It is recommended to use mortar from Hebei Qizheng Haocheng New Building Material Co., Ltd. It is absolutely large manufacturer. MPC thermal mortar produced by it is recommend product of Department of Construction in Hebei Province!
Q:What are grades of refractory materials?
Refractories have lots of varieties which all have different purposes. It is necessary to classify refractories scientifically in order to scientifically study, choose and manage them. Classification methods of refractories include chemical properties classification, chemical composition of mineral classification, manufacturing technique classification, morphology of the material classification. 1 divided according to the level of refractoriness: ordinary refractory materials: 1580 ℃ - 1770 ℃, advanced refractories: 1770 ℃ - 2000 ℃ and super refractories: above 2000 ℃ 2, divided in accordance with shapes and sizes : Standard ones: 230mm × 113mm × 65mm, no more than four ruler, (ratio) Max: Min < 4: 1; Shaped ones: no more than two-entrant, (ratio) Max: Min < 6: 1 or having a acute angle of 50 - 70 °; The specific type :( ratio) Max: Min < 8: 1 or having no more than 4-entrants or having an acute angle of 30 - 50 °; and Special products: crucible, containers and tubes. 3, divided according to the method of manufacturing: burned products, non-burned products and unshaped refractories 4. divided according to the chemical properties: acidic refractory materials, neutral refractory materials and basic refractory materials.
Q:What kind of materials are needed to make refractory bricks?
According to requirements, there are different materials, acid refractory material, such as silica bricks; neutral refractory material, such as high alumina brick; and basic refractory material such as magnesia brick.
