Q:What are the commonly used fire protection materials
Firewall. The fire wall is made of non combustible material, and is directly installed on the base of the building or the reinforced concrete frame or fire proof walls . Fireproof limit of the firewall, according to the current "building regulations", is 4 hours, wheras the specification of Technical specification for concrete structures of tall building is 3 hours. doors resistant to fire, heat in a certain period of time These door usually prevent the spread of fire and gas in the fire resistant wall, staircase, pipe well. Fire door can be divided into steel fire doors, wood fire doors and composite materials fire door according to the material used. According to the limit of fire resistance can be divided into the class A fire door (1.2h), B fire doors (0.9), class C fire door (0.6h); (3) fire window. Windows resistant to fire, heat in a certain period of time It is usually installed in the fire resistance wall or doors; the fire shutter. This roller shutter can be refractory in a certain period of time. It is typically used for heat and fire insulation in escalator with difficulties to install fire resistant wall, fire resistant valve and smoke resistant valve. Fire resistant valve is installed in the ventilation and air conditioning system of air supply and return air duct, usually in the open state, fire, It will be turn off when the pipeline gas temperature reached 70 degrees, can meet the requirement for fire resistance and insulation for gas and fire. Smoke fire resistant damper installed in the exhaust system pipe, when the pipeline gas temperature reached 280 degrees, it will close automatically, insulating fire and gas.
Q:What kind of refractory decorative board has good quality?
The unique design and personalized style of well-known brand "transit" rank highest in the field of domestic refractory slab. It is one of the largest manufacturers of high pressure decorating refractory slab in China. The production base covers an area of 40,000 square meters and the annual output is 4 million. It passes the test of Quality Supervision and Inspection Center of National Fire Protection Building Material and ISO9002 certification. The products pass international standards such as 4586, the United States NEMA and so on.
Q:which is better as household fireproof material ?
If it is from the perspective of fire rating inorganic active insulation material for wall thermal, cement foam insulation board, glass beads of insulation movitrified micro bead thermal insulation mortar, rock wool board, glass wool board, ect.. thermal insulation material are Class A fireproofing, polyphenyl board, extruded sheet, phenolic foam board, Polyurethane board, ect..belong to B1 level fireproofing, if it is used for external wall thermal insulation in decorative board, then rock wool board is more often used.
Q:What kind of refractories do the anode baking furnace use?
5% volume density. 2 , The application results show that it has the energy-saving effect. 4, Withstand voltage strength. The 50MPa prebaked anode baking furnace furnace wall replaces traditional small special-shaped brick with steel fibre reinforced castable precast block: The aluminum content is 45-60%. The iron content is less than 1. I know someone uses andalusite bricks. This method, under the condition of not changing the roasting technique , has excellent resistance to CO. If there are investors, you can complete the overhaul and reconstruction work of anode baking furnace, which is still a precedent in the country. The andalusite bricks are significantly better than clay bricks. The volume density of 5% of it is 2.25. The compressive strength of 40MPa aluminum content is 60%, and the iron content is less than 1. The andalusite is more denser in the structure. Physical and chemical indicators are as following: it has a good anti-corrosive of exhaust gas Na2O. This is because its chemical composition and mineral composition are very suitable for anode baking furnace, which has long life and easy construction and other characteristics.
Q:How many types do refractory bricks have? Where the quality of refractory material is best? What is the model?
Sinosteel Luoyang (Luoyang Refractory Material Plant in the past): High alumina(mainly blast furnace), Gongyi. There are also a series of high-tech materials (silicon carbide, carborundum, etc.) a major producer of high alumina; silicious: Resistant material for steel, glass furnace, cement kiln); magnesia. Divide from uses and divide from chemical texture; silicious(glass furnace): Xinmi, Hennan Province, Lengshui River, coke oven, etc.). As for the models, Yixing and Changxing in Jiangsu Province: Haicheng, Liaoning Province; silicious, I do not understand your intentions; magnesia (nonferrous, steel refining; magnesia: High alumina brick; Dashiqiao area! Please put it in detail.
Q:Who knows what is the requirement for fireproofing of interior decoration materials ?
In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.
Q:Refractory materials are needed for casting metallurgy.
High quality refractory materials can not be separated from the process of smelting metal and casting moulding, because the quality of melting furnace, iron / steel ladle directly affect the chemical composition of the metal liquid, and exert irretrievable influence on comprehensive quality of castings. Classification of refractory materials used in foundry smelting process: refractory brick, siliceous brick, high alumina brick, corundum brick, magnesia brick, magnesia brick, magnesia carbon brick. Unshaped refractory materials: ramming material, castable, refractory cement, silica, magnesia, coating material and light insulation material etc.
Q:What's the definition of fire endurance of the fire-resistant coating for steel structure?
Fire endurance (h): Under the condition of standard fire resistance test, the time when the building components, accessories, or structure is subjected to fire to the time when they loose stability, integrality or thermal insulation is called fire endurance which is showed in time. Steel is the kind of building material that is nonflammable with many properties of seismic resistance and bending resistance. In practical applications, steel can improve the load capacity of buildings in a relative way, meet the needs of buildings design, beauty and mould, and it can also avoid the defects of poor flexibility and tensile strength of buliding materials like concrete. Therefore, steel is quite popular in the construction industry, and it is widely used in single-story or multi-storey skyscrapers, plants, warehouses, waiting rooms and airport terminals, etc. However, as a kind of building material, it has some unavoidable defects in fire prevention. That is its mechanical properties like yield point, tensil strength and elasticity modulus will decrease dramatically with the rise of the temperature.
Q:Who knows the external wall thermal insulation materials fire rating requirements?
The basic requirements of ratings. The design should comply with relevant state regulations and standards, the combustion performance used in exterior insulation material shouls be level A and not less than the level B2 fireproofing material. The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height
Q:who knows the requirements of refractory for forge furnace?
Forging heating furnace working temperatures above 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. refractory is generally required to have the following properities: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.
