Q: what kind of refractories is used to make the industrial silicon furnace mouth long life?: Fused zirconia corundum brick, the smelter of the glassworks is used this kind of lining, and you can contact by private letter.

Q: which kind of refractory is used in golden smelting furnace? How about his using temperature: generally the price of the quartz sand refractory material is higher and the temperature can meet the requirement of 2000 degree.

Q: Fire rating of decoration materials: You can refer to (code for fire protection design of buildings)

Q: what is the common materials for home fireproofing material?: 1, lumber core 2,decoration panel 3 , plywood 4 density board 5,chipboard 6 fireproof?panel, 7.gypsum board Hope to adopt my opinion

Q: what's the varieties of thermal insulation material with A level fire?rating?: Inorganic thermal insulation material can do it, such as glass wool,rock wool,foam glass,etc. phenolic foam materials in organic foam material is special. phenolic foam not only has good thermal insulation properties but also can be composited with steel plate and other materials, A class thermal insulation materials that reach A class combustion performance include: rock (mine) wool, foam glass, EVB, etc. thermal insulation materials with A class combustion performance mainly include: phenolic aldehyde,gelatine powder polyphenyl granule, etc. thermal insulation material of fire barrier zone can use rock (mine) wool, foam glass, EVB and other materials with A class combustion performance.

Q: Does refractory belong to metallurgical auxiliary materials?: Refractory is widely used in industrial circle, such as metallurgy, chemical industry, petroleum, mechanical manufacturing, silicate and power, and its coonsumption is the maximum in metallurgy, accounting for 50% to 60% in total output. In order to improve slag-corrosion resistance of furnace lining, usually choose carbon-containing refractory. Refractory of various furnace lining are respectively: For the body, it is clay brick; as for the lower part, bosh and middle, it is SiC brick; for furnace bottom, it is carbon brick. Lattice brick is an important refractory product used in air heating furnace and regenerative chamber. Refractory is widely used in metallurgy. In order to improve slag-corrosion resistance of lining. Central line in tuyere and hearth are high-alumina brick. Refractory consumption is the maximum in metallurgy, accounting for 50% to 60% in total output. For the bosh and middle, it is SiC brick. In order to improve its thermal storage capacity: The furnace stack is clay brick. It is defined as refractory where the physical and chemical properties allows its use in high temperature environments; The lower furnace body

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: Could you tell me how does fire protection standard of decorative material is divided?: Building materials can be divided into four levels according to combustion performance (non-combustible, flame retardant, flammable, flammable). According to the Code for Design on Building Fire Protection and Prevention (GBJ16-1987) (revised in 2001):, the fire risk of production or storage is divided into a, b, c, d, e classes. Divided by plate material: structure material, base layel materials and fabric; Divided by fire protecrtion type: easy to burn, difficult to burn, flame retardant, incombustible material. Material has no fire rating, only the different from the time of combustion limit. Combustion performance grade A of commonly used adornment material: granite, marble, terrazzo, cement products, concrete products, gypsum, lime products, clay products, glass, ceramic tile, Mosaic, steel and alloy. I hope my answer can help you.

Q: who knows the technology of fireproofing material?: First: Firstly, you should produce the recipe and prepare the raw materials, for example, if you prepare to produce 1 ton, you should compute the recipe sheet of 1 ton producing; check whether the raw materials are complete; second: make the color and filler thick liquid; add water in order and proper auxiliary in a low speed, then put color and filler (generally we should firstly add something with large oil absorption), wash the meachine after putting the powder. Then seperate them for about 20 miutes in a high speed, until the fineness is qualified; of course, if you need sander, i think you only need sino-soviet differential powder material and non-obvious particles. Third: Paint mixing period: after making the color and filler thick liquid, reduce the roll speed into about 600 roll per minute, add emulsion and proper auxiliary, finally adjust PH and viscosity.
