Q:how to divided the external wall thermal insulation materials fire rating
The external wall thermal insulation materials is divided by fire rating: 1. The thermal insulation material of level A combustion performance: inorganic fiber spray coating, glass wool, foam glass, foamed ceramics, rock wool, foam cement and hole-closed perlite, etc. 2. combustion performance is level B1 insulation materials: Extruded polystyrene board (XPS) after special treatment / Special treatment of polyurethane (PU), phenolic aldehyde and gelatine powder polyphenyl granule 3, combustion performance is level B2 insulation material: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), 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:Fire resistance and evaluation of refractory for casting
Because of their different shapes and conditions, various refractories are used to explain their fire resistance with different indexes, and the test methods are also different. In general, the refractoriness of unshaped refractories; the softening temperature of formed refractory products; the change of the reheating line of heat insulation materials at high temperature.
Q:Which industry does refractory belong to? Does it belong to construction industry?
I do not recognize all the answers. No matter what kind of refractory can be used in construction. Biulding syove or kiln is construction. So personally, it belongs to construction indusrty.
Q:Detailed description of magnesia dolomite refractory material?
In the cement kiln firing zone, the f-CaO in the dolomite material is easily combined with the C2S in the clinker to form C3S, so the kiln cover can be easily hung, and the kiln crust and the refractory brick are firmly combined and easy to maintain.
Q:What are included in fireproofing materials?
Incombustible material of construction fire-proof material Grade A: Cement, stone, steel, coat, glass, aluminium alloy, ceramic tile, etc.; nonflammable material Grade B1: Fireproof panel, rock wool.
Q:Which kind of refractory does insulation board belong to ?
Q:What types does refractory floor include?
There are many types refractory bricks, including silicon aluminum refractory brick, the leading product in refractory bricks. And its high temperature resistance can reach up to 600 degree centigrade or more, so it is an excellent refractory brick. And this high-alumina refractory brick is very suitable for metal industry for its strong practicability. Another one is alkaline series refractory brick, including magnesite refractory brick, and these two bricks are good materials resistant to high temperature.
Q:How many refractories are there for boiler above 1200 ℃?
Ordinary clay brick is for burning layer, red brick for external wall, light clay brick for thermal insulation layer, built by clay refractory mortar. Sindeyuan Refractories.Hope you adopt. Thank you. In fact, there are many manufacturers producing furnace burden. We has been using products of Huaheng, which are anti-erosion, easy to construct and can improve production efficiency, reduce steelmaking cost.
Q:which kind of material is chosen for fireproofing window?
(1) window frame uses steel frame or wooden frame with certain strength that can safeguard the integrity and stability of the components. (2) steel frame and mound layer can choose galvanized steel sheet or stainless steel plate. Its selection criteria conform to the article 5.1 in GB12955 Steel Fireproof Door General Technical Condition. (3) the selection criteria of wooden frame and mound layer should conform to the article 5.1 in GB12955 Wooden Fireproof Door General Technical Condition. (4) the inside filler material of steel, wood frame should use incombustible material. (5) fire-resistant glass can choose test approved products without affecting the fire resistance of fireproofing windows . Light transmittance of glass should not be less than 75% of same layers commom sheet glass. (6) the sealing material between the frame and the fire-resistant glass should use flame retardant materials, it can play a role of fireproofing and smoke insulation in the fire.
