- Q: What is the importance of silicon powder in refractory processing?
- it can certainly improve the fire resistance
- Q: How to detect the acid resistance of refractory? Is there any standard? Thank you
- There is a standard. However, the range what you said is a little big, it's difficult for me to say. But though the scope is a bit big, it should be: You can check the industry standard network, to see whether you can check it.
- Q: Who knows what is the external wall thermal insulation materials for level A fireproofing?
- In general, external wall thermal insulation materials can be divided into level A and level B by combustion grading. Level A is non-combustible material, and level B is combustible materials. A few years ago, the fire of the CCTV Building and Shenyang Hotel put the blame on the level B material. At present, the level A material is widely used, and the prices of same level A materials may be even cheaper than the level B material. Level A material is generally divided into thermal?mortar, phenolic foam board, rock wool board and foam cement board. I hope this information can be helpful to you. Hope you adopt.
- Q: What is the fire endurance of ceramsite concrete blocks?
- The heat conductivity coefficient of grade 800 hollow building blocks in ceramsite concrete is 0.23 and fire endurance is 4h. Ceramsite concrete has strong construction adaptability. It can not only compound concrete material with different unit weight and strength(It changes with the structure of thermal insulation or bearing structure) according to the different purposes and functions of buildings, but also is easy to construct. It is suitable for industrial production of a variety of construction methods. It can not only make all types of components(board, block, girder, column, etc) by using production process, but also can use mechanization construction of cast-in-place. The strong adaptability of construction of ceramsite concrete is not comparable to any other lightweight building materials(such as air-entrapping, etc.).
- Q: Concrete composition and function of magnesia bond used in refractory
- The main component of magnesia binder is silica powder and six partial, the mechanism is gel combination, and six can react with magnesium (basic refractory) to produce complex compound, and improve the strength of products
- 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: How many fire endurance grades are the AAA fire resisting shutter divided?
- The fire shutter is divided into A / B / C classes. The refractory limits are not less than 1.2 /0.9 /0.6 hours. References to "general technical specification for steel fire resistance rolling shutter door GB 14102-93". 4.3 4.3.1 Classification according to fire resistance time. The common steel fire resisting shutter(see Table 3) The categories of the codes of the refractory time hF1 1.5F2 2.04.3.2 composite steel fire shutter composite steel fire shutter(see Table 4). Table 4 and Category Code refractory time hF3 2.5F4 3.04.4 refractory press time, smoke performance classification 4.4.1 ordinary steel fire anti-cigarette curtain (see Table 5) Table 5 and category code leak smoke refractory time h (20Pa pressure) FY1 1.5 ≤0.2m3 / m minFY2 2.0 ≤0.2m3 / m min4.4.2 composite steel fire anti-cigarette curtain (see table 6) table 6 and category code leak smoke refractory time h (20Pa pressure) FY3 2.5 ≤0.2m3 / m minFY4 3.0 ≤0.2m3 / m min excerpt complete fire shutter when the fire district for fire resistance of 3 hours, the opening portion on the firewall setting fire shutter fire resistance of 1.2 hours. **** Fire resistance of 3.0 hours called premium (fire back surface). "Construction Regulation" is mentioned in setting up a firewall and used as the separation of the fire resisting shutter and the fire?compartments. When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the fire endurance should not be less than 3.00h; When taking the fire back surface temperature rise as the fire resistance standard of the fire resisting shutter, the two sides of the roll should have protection of ?closed automatic water spray system, and the duration of water spray system should not less than 3.00h. In summary: The fire resisting shutter can be divided into: Grade, A, B and C looking to adopt
- Q: The manufacturing technique of refractory material
- The major components of alkaline refractory material include magnesium oxide and calcium oxide. The commonly used alkaline refractory material is magnesia bricks. The magnesia bricks with 80%～85% magnesium oxide has good resistance to basic slag and slag and higher refractoriness than clay bricks and silica bricks. It is mainly used in open hearth, oxygen blowing of converter, electric furnace and smelting non-ferrous metal equipment and other high temperature equipment. Refractory materials applied on special occasions include high temperature oxide refractory materials such as alumina, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, etc., refractory compounds such as carbide, nitride, boride, silicide and sulfide, etc., and high temperature composite materials, including metal ceramics, high temperature inorganic coating and fiber reinforced ceramics, etc. Consult and find reference for efractory materials production equipment, go to http://hi.baidu.
- Q: What is glass furnace used high-grade refractory materials?
- Corundum brick, such as alumina hollow ball brick. In addition, in the key parts of the glass furnace needs to use chromium zirconium corundum material. I'm salesman of zibo lei bao refractories company. The softening temperature of corundum mullite brick is 1500 degrees. So glass melting furnace needs to use refractory materials which high temperature resistance is more than 1600 degrees.
