- Q: What are the refractory stocks?
- The company produces energy saving, environmental protection type functional refractory materials and unshaped refractory materials. It is the main functional refractory material and unshaped refractory production enterprise in china. Company's products to new green high-quality refractory materials, energy saving and environmental protection as the leading iron and steel industry technological progress and improve the level of technology and equipment to adapt to meet the "development policy" refractories industry to develop industry, has a strong competitive advantage in the market. The main domestic refractory products company can only use part of the products of refractory materials production of iron and steel industry, iron and steel industry production and Pu resistant can be used in the vast majority of refractory products, iron and steel industry with the most complete refractory products. Therefore, the future development of the company is closely related to the prosperity of the iron and steel industry. More than more than 2000 enterprises in refractory industry, the company is the largest supplier of refractory materials in China, and the market share is less than 2%. Iron and steel group integration will inevitably lead to the overall contract cost control, supplier refractory decreases by seventy or eighty to two or three. The company's overall contract accounted for 37% (Montreal 68%), the overall contract increase will enhance the market share and profitability. China's urbanization, industrialization and investment in the 4 trillion infrastructure will stimulate sustained and rapid growth of China's steel demand. Therefore, in the long run, the prospects for the development of refractories for iron and steel are broad.
- Q: What are grade classifications of the external walls fireproofing material?
- There are many kind of external walls fireproofing material, according to the document No. 65, the grade of external wall fireproofing material can be divided into: Level A is inorganic insulation non-combustible materials, such as cement foam insulation board, vitrified?micro bead?thermal insulation?mortar, rock wool board, glass wool panels. Level B1 is nonflammable material, mostly are organic material which has added a relatively large amount of flame retardant, such as polystyrene board, extruded sheet, phenolic foam board and polyurethane board. Level B2 is flame-retardant materials, and also known as fire-retardant materials, mostly are organic insulation materials with appropriate amount of flame retardant.
- 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: 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 is the classification standard of fireproofing material levels?
- Standard: Class A: Incombustible building material, almost without burning. class A1: Non-combustible, no open flame,class A2: Non-combustible,it needs to measure smoke and be qualified. Class B1: Nonflammable building material: Nonflammable materials have good flame resistance function. when it contacts open fire or is under high temperature, it's difficult to burn and be spreading rapidly, and will stop burn after removing the combustion?source. Class B2: Combustible?building?materials: Combustible materials have good flame resistance function. when it contacts open fire or is put in the air at high temperature, it will immediately burst into flames, and easily result in the spreading of fire, such as wooden column, timber roof truss, timber beam, wooden stairs, etc. Class B3: Inflammability building materials, without any flame resisting effects, easy to burn, and has large danger of fire disaster.
- Q: Would you like to know if there are any enterprises in Mianyang that need fire-resistant materials?
- Smelting and casting needs, need more long double
- Q: What is the definition and classification of amorphous fire resistance materials?
- 9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
- Q: Who can tell somthing about how to choose fire resistant rating of fire resistance rolling shutter doors?
- According to the fire endurance, fireproof doors can be divided into A-grade, B-grade and C-grade, whose fire endurance should not be less 1.2h, 0.9h and 0.6h respectively. A-grade fireproof doors can be even applied to the material whose fire resistant rating is at secondary level. "Building Regulations" mention that fire resisting shutter can be used as partition of fire?compartment in those places where setting firewalls is not so easy. When using fire resisting shutter whose fire endurance includes unexposed surface temperature rise, its fire endurance should not be less than 3 hours. When using fire resisting shutter whose fire endurance doesn't include unexposed surface temperature rise, it should install closed independent automatic sprinkler system for protection on both sides, and the sprinkler sholud last at least 3 hours.
- Q: how long is the fire endurance of plasterboard?
- fireproof endurance can reach a maximum of 4hours, suitable for a variety of public buildings firewall, and partitions for public exit passageway, reaching standard level of fireproof. the lightweight partition made of gypsum board and steel stud is mainly for dividing architecture space. Rock wool can be filled in the mddle according to its design requirements, using different series of gypsum board, steel stud. the walls may have fire resistance and sound insulation property of various degrees.
- Q: I wanna ask about the thermal insulation material fire resistant level?
- The inorganic have glass wool \ foam glass Bian \ the best of organic is phenolic foam \ phenolic foam composite cement layer is level A.
