Q:I wanna ask about the building insulation materials fire rating?
In China, the main external insulation materials are divided into level A, level B1, level B2 and level B3. According to the current "Combustion Performance Classification Method of Building Materials", level A thermal insulation material is incombustible material and inorganic insulation material. However, there are few level A thermal insulation material on the current market, only glass wool, rock wool board, foam glass and vitrified micro bead. However, compared with level A insulation material, the organic insulation materials are popular in the market. Level B insulation material can be divided into three levels, level B1 is flame-retardant, level B2 is flammable, and level B3 is flammable. Level B1 nonflammable thermal insulation material is determined by the fire endurance of the material, in addition, different parts of material is divided differently! More common is EPS / XPS insulation boards which have added flame retardant through special treatment. B2 level of combustible insulation materials, common to EPS expanded polystyrene foam insulation board and XPS board, that is, we often say that the general board. The ignition point of this material is very low, and it will release a large amounts of harmful gases in the combustion process. level B3 flammable insulation material is a kind of thermal insulation material which mainly made of polyphenyl foamed. Since this material is highly flammable, it has been eliminated. Civil construction insulation materials, popular building insulation materials in China's current market are mainly made by three organic foam, such as EPS (molded polystyrene board), XPS (extruded polystyrene board) and PU (polyurethane)
Q:How much is the content of boron carbide in refractory material?
Is it available to iron materials?. Answer: It can be applied to all products, what you need is just a general proportion. Nevertheless, you’d better tell me what product it is exactly.
Q:What are the construction measures of refractory material in winter? Please descriptive briefly.
The temperature is low in winter, so refractory bulk materials should be stirred evenly on time to avoid freezing.
Q:What is the concept of lightweight refractory material?
Lightweight refractory material has high porosity, mechanical strength and erosion resistance. Compared with normal refractory bricks, it is a kind of refractory material with large volume shrinkage in high temperature, low thermal conductivity and small bulk density. It is used as thermal insulation material in industrial furnace and other thermal equipments. It has poor wear resistancel.
Q:Does anyone know about the fire resistance period of thin fireproof coatings?
The thin fireproof coatings will be expanded when exposing to open fire, and produce the inert gas to extinguish fire, but they will do harm to people, and the coatings are not stable, and the weather resistance and service life of which are short. According to the state regulations, the thin fireproof coatings have the highest fire resistance of only 2.5 hours, while the thick steelwork fireproof coatings have a fire resistance of 3.0 hours or more.
Q:Does anyone know about the A-level fireproof materials?
A-level decorative integrated plates of thermal insulation, water- and fire-proofing mainly can prevent fire and insulate heat with A-level fireproofing glass fiber as thermal insulation materials. The classification of A1-level external wall materials of thermal insulation, fire- and water-proofing: First, external wall thermal insulation materials: 1. silicate thermal insulation materials 2. gelatine powder polyphenyl granules 3. steel wire gauze picking cement cystosepiment (grs board) 4. extruded sheets; Second, roofing materials: 1. xps extruded sheet 2. EPS foam board 3. perlite and perlite brick 4, vermiculite and vermiculite bricks; Third, heating and air conditioning materials: Polyurethane, rubberplastic sponge, polyethylene, polystyrene foam, glass wool, rock wool; Four, steel structure materials: Polystyrene, extruded sheet, Polyurethane board, glass wool roll mat, etc.
Q:Kinds of refractory mortar
Refractory mortar can be divided into ordinary refractory material and special refractory material. Ordinary refractory materials can be divided into acidic, neutral and alkaline refractory materials chemical properties. Special refractory material can be divided into high temperature oxide, refractory compounds and high-temperature composite materials according to their components. Furthermore, according to refractoriness, it can be divided into general refractory products (1580 ~ 1770 ℃), high grade refractory products (1770 ~ 2000 ℃) and super refractory products (2000 ℃ above). It can be divided into bulks (standard bricks, special-shaped bricks, etc.), special shapes (crucible, sagger, pipe, etc.), fibrous (aluminum silicate, zirconia filter and boron carbide , etc.) and indefinite shape (refractory clay, pouring materials and ramming mass, etc.). According to the sintering process, it is divided into sintered products, fused cast products and melting jetting products.
Q:What is required to do refractory material?
Can you be more specific about what aspect?
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 refractories are accessible with ease in daily life?
Refractory mortar. Thermal insulation refractory materials include diatomite products, refractory castables, monolithic refractories, carborundum bricks, gun-mix refractories, semi-silica bricks, borides, beryllia, silicide, calcium oxide, high alumina refractory brick, refractory coatings, corundum bricks, fireclay bricks, silicon nitride bonded silicon carbide bricks, chromium hemitrioxide and other refractories. What refractories can be found mostly in the market? Common refractories. Common refractories include silica bricks. The mostly used unshaped refractories include fettling, ramming refractories, castable refractories, plastic refractories, refractory clay, gun-mix refractory, sling refractories, refractory coatings, lightweight refractory castables, stemming etc. The mostly used insulating refractories include diatomite products, asbestos products, insulation panels, etc. The mostly used special refractories include AZS bricks.
