- 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 the meanings of azs, 34% and ec in fused brick?
- The fused brick, also called zircon corundum brick, is shorted as AZS for three chemical components in Al2O3-ZrO2-SiO2 ternary diagram. I don't know the meaning of EC.
- Q: What is the use of refractory?
- It is equivalent to a protective layer. It can be used to protect structural materials from being direcctly attecked by high tempereture or internal gases. General structural materials are steel, so the main function is resistant to fire and high temperature. In literal meaning, refractory is a fireproof material. Steel is easily deformed and wore. Structural materials can not directly touched with solid and liquid. Refractory materials are generally used as a protective lining of structural material, so it is necessary to be protected.
- Q: What are the requirements of the performances of brasque refractory?
- It is a kind of inorganic non-metallic material whose refractoriness is not lower than 1580 ℃. Refractoriness is the centigrade?temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down But only refractoriness can not fully describe the refractories, 1580 ℃ is not absolute. Refractory is now defined as material of physical and chemical properties allowing to be used in high temperature environments. Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
- Q: How to divided the grade of external wall thermal insulation materials?
- Synthesized the three versions of GB8624 (1997,2006,2011), external wall thermal insulation fire?rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. There are many technical indicators to make specific division, but I partly cannot report for a while, because it is very professional and technical. I hope I can help you!
- Q: Who knows about the grade C fireproof door materials?
- grade C fireproof door materials: 1. the doorframe raw materials of grade C fireproof doors: the galvanized?steel?sheet is no less than 1.2 mm(the thickness of steel plate is no less than 1.5 mm when the height and width of doors are more than 2.1 m and 1.2 m respectively). 2. the door leaf raw materials of grade C fireproof doors: the thickness of galvanized?steel?sheets is no less than 0.8 mm. 3. the reinforcement raw materials of grade C fireproof doors: the thick?steel?plate is no less than 1.2 mm, if there are bolt-holes, the thickness of which is no less than 3.0 mm. 4. filler: The fireproofing filling materials that fit the environmental and standard needs(for instance, door leafs are filled with perlite fireproof materials inside, and doorframes are filled with fire-resistant cement) meet the test criterion promulgated by the relevant state departments. 5, the sealing requirements: there are seal grooves in doorframes and within which are embedded with refractories.
- Q: How to deiron refractory?
- Deironing refractory can take physical methods into consideration, such as magnetic?separation, reselection, etc. And it can also take chemical methods, such as flotation.
- Q: What are the main characteristics of the sic refractories?
- The physical properties of SiC refractories include structural properties, thermal properties, mechanical properties, usability and job performance. The structural properties of refractory include porosity, bulk density, water absorption, air permeability, an the distribution of pore size. The thermal properties of refractory include thermal conductivity, thermal expansion coefficient, specific heat, heat capacity, thermal diffusivity, and thermal emission rate. The mechanical properties of refractories include withstand voltage strength, tensile strength, anti bending strength, torsional strength, shear strength, impact strength, abrasion resistance, creep resistance, adhesive strength, and elasticity modulus. The usability of refractories include refractoriness, load softening temperature, linear?change?on?reheating, thermal shock resistant performance, slag resistance, acid resistance, alkali resistance, hydration resistance, corrosion resistance to CO, conductivity, and inoxidizability.
- Q: It the Special Fire-Proof Material belonged to ceramics? Is there a national standard of the Special Fire-Proof Material?
- The fiber and reinforcing material of the metal ceramic is also belonged to the Special Fire-Proof Material. ~~~~GB is too much trouble, GB online should ~~~ Lei Bao Refractories for you. The high temperature inorganic coating. 5. The refractory compound. 3. The high melting point oxide. You can search it on the internet according to the classification~~~~ The special refractories can be divided into five categories: 1. metal ceramic
- Q: Who knows what material is in the center of fireproof rolling curtain?
- made of inorganic super fireproof rolling curtain: Glass fiber cloth ceramic fiber cloth (reinforced stainless steel wire) ceramic fiber blanket aluminum foil cloth. Hope my answer will help you.
