- Q: How to use fire-resistant soil?
- Clay refractory soil 1, characteristics and uses: Clay refractory brick is a weak acid refractory material, its thermal stability is good, suitable for hot air furnace, all kinds of boiler lining, and flue, smoke room, etc.. 2, product specifications form: standard shape, general, special-shaped and special-shaped brick. Physical and chemical properties of fireclay bricks.
- Q: Who knows how many fire heat preservation material are there?
- They can be divided into wood fire, steel fire and stainless steel fire. Wooden fireproofing material is light weight, easy for installation and second decoration, as well as all types of civil construction and some industrial buildings. It can be realized through inorganic insulation materials, such as glass wool, rock wool, foam glass etc.. The phenolic foam materials inside organic foam material is more special. Phenolic foam does not only have a good thermal insulation performance, but also can be combined with steel and other materials, to achieve a class A fire retardant level. Class A thermal insulation include: 1 thermal insulation materials with class A combustion performance Fire insulation materials of fire barrier zone can use class A material with class A combustion performance in rock (ore) cotton, foam glass, inorganic thermal insulation mortar.
- Q: Who knows the setting requirements of roofing fire barrier zone?
- curtain wall style architecture should meet the following requirements: The space between the inner cavity of the base wall and curtain wall and base wall, pier?between?two?windows, window sill wall and skirt wall should be sealed by the fire-proof?sealing?material at each floor. I hope I can help you!
- Q: What does the function of SiC for refractories?
- The main feature is with high temperature, the wear gold resistance of refractory is recognized by our customers. Hope my answer will help you.
- Q: What's the B grade fireproofing material?
- B1 grade ceiling material: gypsum board, fobrous plasterboard, cement particle board, mineral wool decorative acoustic panels, glass wool decorative acoustic board, perlite decorative acoustic board, flame retardant plywood, flame retardant medium density fiberboard, rock wool decorative sheet, flame retardant wood, aluminum foil composites, flame retardant phenolic laminate, aluminum foil glass fiber reinforced plastic composite material, etc.; B1 grade wall material: gypsum board, fibrous plasterboard, cement particle board, mineral wool board, glass wool board, perlite board, flame retardant plywood and medium density fiberboard, fireproof plastic decorative sheet, nonflammable double-sided particle board, multicolor coating, flame retardant wallpaper and wall cloth, flame retardant simulated granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plates, PVC plastic clapboards, high-strength and lightweight composite wallboards, fire-retardant molded wooden composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.
- Q: How should fireproof building materials be ranked?
- 5. Civil building 5.1. Fire resistance rating, number of layers and floorage of civil buildings 5.1.1. Fire resistance rating of civil buildings should be classified into four levels of first, second, third and fourth. Unless otherwise specified in the code, the combustion performance and fire endurance of building components with different fire resistance rating should be no less than that of the regulations in Table 5.1.1. Table 5.1.1: Combustion Performance and Fire Endurance (h) of Building Components (Figure) Note: 1. Unless otherwise specified in the Code, the fire resistance rating of the building with wooden pillars as load-bearing and incombustible material as the building wall should be the fourth level; 2. For the suspended ceiling of the building with the second level of fire resistance rating, if it uses non-combustible component, it won't be limited in its fire endurance; 3. For buildings with the second level of fire resistance rating, if it is really difficult for the partition wall of rooms with the area of no less than 100m2 to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.3h; 4. For buildings with the first or second level of fire resistance rating, if it is really difficult for the partition wall of both sides of the evacuation walk to implement the regulations of the Table, the partition wall can adopt the non-combustible component with fire endurance of no less than 0.75h. 5. Fire endurance and combustion performance of the residential building component can be implemented in accordance with the provisions of current national standard GB 50368 "Residential Building Code".
- Q: What is the fire endurance of fireproof glass cotton?
- Good thermal insulation and thermal insulation. thermal insulation and thermal insulation depends on the heat conductivity coefficient of glass?silk λ=0.043W/m2K. good fireproof?performance, it's fire-resistant capacity is more than 1000 ℃.
- Q: whether the aluminum silicate thermal insulation material is fireproof or not?
- aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
- Q: Detailed description of magnesia dolomite refractory material?
- In the cement kiln firing zone, the f-CaO in the dolomite material is easily combined with the C2S in the clinker to form C3S, so the kiln cover can be easily hung, and the kiln crust and the refractory brick are firmly combined and easy to maintain.
- Q: What are the differences of ceramics and refractories? Is the ceramics belonging to refractories?
- No In the high school chemistry, the former is talking about the traditional inorganic material, the latter is belonged to the new materials.
