- Q: What are unshaped fire-resisitance materials?
- Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
- Q: What is streaming fireproof material?
- Streaming fireproof material is castable refractory that can flow and degas without virbration, which is suitable for thin-wall or places that cannot be molded by vibration because of complex shapes. Well, appropriate amount of water is necessary for it. Its characteristic goes that it can be cast into various shapes of construction body without virbration and it will not reduce or not significantly reduce the performance of castable at the same time.
- Q: How many kinds of A-level fireproof and thermal insulation materials are there?
- Inorganic insulation materials basically can achieve the goal, such as glass wool, rock wool, and foam glass. The phenolic foam in the organic foam material is special. Phenolic foam is not only good at insulation, but also good at compounding with steel and other materials to achieve A-level performance, and the A-level insulation materials are: Rock(ore) wool, foam glass and inorganic thermal insulation mortar.
- Q: How is the grading of the level A new material fire insulation material?
- The thermal insulation materials are generally divided into level A and level B according to the flame rating. Level A is the non-combustible material, and level B is the combustible materials. The level B material is to blame for the fire in Shenyang hotel in CCTV building a few years ago . At present, the level A materials are widely used, with some prices even cheaper than the level B material. A level is roughly divided into insulation mortar, phenolic board, rock wool board and foam cement board, ect.
- Q: What is the function of refractory in ceramics?
- In addition, the quality of refractory determines the finish and color of ceramic glaze.
- Q: Who knows about the fire endurance of grade C fire doors?
- It can be classified according to the fire endurance and thermal insulation performance: The fire endurance of grade A fire doors is not less than 1.5 hours; that of grade B fire doors is not less than 1.0 hours; and that of grade C fire doors is not less than 0.5 hours. I hope my answer can help you.
- Q: How many refractories are there for boiler above 1200 ℃？
- In addition to refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and the like. Refractories often used are azs brick, corundum brick, direct-bonded?magnesia-chrome?bricks, carborundum brick, silicon nitride bonded silicon carbide brick, nitride, silicide, sulfide, boride, carbide and other nonoxide refractory materials, calcium oxide, chromium hemitrioxide, aluminium oxide, beryllia and other refractories. Thermal insulation refractory materials often used are diatomite product, asbestos product, insulation?board,etc. Unshaped refractories often used are repairing?mass, ramming?mass, castable refractory, plastic refractory, refractory mortar, refractory gunning mix, sling refractory, refractory coating, lightweight refractory?castables, stemming, etc.
- 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 is the fireproofing requirements of external wall thermal insulation materials?
- External wall thermal insulation materials fire rating regulations, 1, the height of a building is greater than or equal to 100m , the combustion performance of insulation materials should be level A; 2, the height of a building is greater than or equal to 60m but less than 100m, the combustion performance of insulation materials should not be less than the level B2. When using level B2 thermal insulation material, every layer should set horizontal fire barrier zone 3,The height of building is be equal or greater than 24m but less than 60m, the combustion performance of thermal insulation material should not be less than the level B2. When using level B2 insulation material, each two-layer should set fire barrier zone ; 4, the height of building is less than 24m, the combustion performance of insulation materials should not be less than the level B2. Besides, when using level B2 thermal insulation material, each three-layer should set a horizontal fire barrier zone.
- Q: Who knows the fire endurance of rock wool color plate?
- I'm glad to answer your question and offer you some of my experiences, for reference only. In fire?safety?rules, it can be divided into non-combustible component, hard-combustible component, combustible component according to the combustible degree of building materials. Rock wool board is building board recombinated artificially by fibers processed by coated steels and inorganic minerals like basalt mineral, because steel plate and rock wool which is the main components are non-combustible material, so rock wool board should be considered as non-combustible component. The fire endurance of rock wool board has its own judging criteria. Lose sustaining power, integrity and fire insulation function. Its fire endurance is within 2 hours.
