Q: How many kinds of A-level fireproof and thermal insulation materials are there?: 1. foam insulation board refers to foam ceramic insulation panels whose raw material is inorganic ceramic which is calcinated at high temperature with abbreviation of ceramic insulation board 2.Composite cement foam insulation board is a hydrophobic lightweight closed-cell insulation board whose main materials are cement, fly Ash, and silica fume which has been foamed, cured and cut. 3. aerated concrete panel is a lightweight concrete panel which has been autoclaved with lightweight materials, siliceous material and gas former as its raw materials. 4. rock wool panel, with natural igneous rock wool as its main raw material, is a cotton which is melted in high temperature by centrifugation and is pasted by thermosetting resin.

Q: What is the fire endurance of ceramsite concrete blocks?: What is mentioned in fire?safety?rules is that the fire endurance of 240mm thick hollow brick of ceramsite concrete is 2.9h, so 190mm thick hollow brick is 3h. B05 thickness(mm), fire endurance(h). Combustion performance 100 4.0. Non-combustible component 150 6.0200 8.0300 〉8.0B06 100 〉4.0150 〉6.0200 〉8.0300〉8.0: The fire endurance performance of building blocks wall in the table is taken from the Tianjin Construction Standard "light steam pressing aerated?concrete?block" DB / T29-128.

Q: Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks: Exports should be fumigated outside of South East asia. Pallet packing is the most common, convenient and inexpensive.

Q: I would like to know if there is any requirement for refractories in the crucible type high-frequency smelting furnace Worry！ I hope you can help me! This time!: High enough for high temperature resistance. Refractory materials for crucibles shall be subjected to a high temperature greater than 1700 DEG C and the softening temperature shall be greater than 1650 DEG c;

Q: What material is used to make furnace pipe of refractory bricks?: Refractory brick is called refractory?brick for short. It is a kind of refractory material fired by using refractory clay or other refractory materials. Faint yellow or brownish. It is mainly used in building smelting furnace and has resistance to high temperature 1,580 ℃ -1,770 ℃. Also known as refractory?brick. It is refractory material with a certain shape and size. It can be divided into burnt brick, unburned?brick, fused brick (fused cast brick), fire-resistant insulation brick according to preparation technics; It can be divided into standard brick, ordinary brick and special-shaped brick, etc according to shape and size. It can be used as high-temperature building material and structural material of building kiln and all kinds of thermal equipment. It can also withstand a variety of physical and chemical changes and mechanical action under high temperatures. For example, fireclay brick, high alumina brick, silica?brick, magnesia brick, etc.

Q: Who knows how many kinds of fireproof insulation materials are there in the market?: The so-called A-level materials in fire insulation materials, namely, the WW non-combustible insulation materials, and the WW material s are A-level. Inorganic fireproof and thermal insulation materials can be used as wall insulation materials to replace red bricks, therefore, they, as thermal and cold insulation materials, can reduce the thickness of walls, and save energy, as well as expand applicable areas indirectly, decreased structure weight. They are very good.

Q: What kind of refractories do the anode baking furnace use?: Use refractory bricks.

Q: what is the Specifications Grading for Fireproof rubber insulation materials ?: External insulation materials, welded wire mesh matt external wall insulation, external wall thermal insulation mesh matt. 1,inorganic activel thermal insulation materials 2,silicate?thermal?insulation?material 3,ceramic thermal insulation 4, gelatine powder polyphenyl granule, 5,teel wire gauze picking cement cystosepiment（Estazolam platepowder particles)6 extruded sheetXPX. 7,Rigid polyurethane coating at the scene, Polyurethane insulation board8,rigid polyurethane foam,9EPS foam board roofing materials. 1, a ceramic insulation board 2, xps extrusion board 3, perlite and perlite brick 4, vermiculite and vermiculite brick heating, air conditioning Material: Phenolic resins, polyurethane waterproof thermal insulation integration, sponge rubber, polyethylene, polystyrene foam, glass wool, rock wool Steel material: Polystyrene, extruded sheet, polyurethane panels, glass wool carpets and the like. Five inorganic thermal insulation materials: Foam cement, DY inorganic active insulation system super thin vacuum insulated panel for building external walls .

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: What are the additives and recipes of refractory?: Water reducing agent is to evidently reduce mixing water content while keep the slamp value of refractory castable almost invariant, also known as fluid loss agent. Water reducing agent itself cannot have chemical reaction with material component or compose new chemical compound, but it just seemingly has physical and chemical reactions. The binding agent of refractory castable is calcium aluminate cement combined with clay and oxide micro powder. In commonly used water reducing agents, the inorganic includes sodium pyrophosphate (Na4P2O7), sodium tripolyphosphate (Na5P3O10), sodium hexametaphosphate [(NaPO3) 6], super sodium polyphosphate (Na2P4O11), sodium silicate (Na2O · nSiO2 · mH2O), and so on; the organic includes lignosulphonate water reducer (sodium lignosulphonate, calcium lignosulphonate); naphthalene water reducer (naphthalene sulfonate or naphthalene homologues with formaldehyde condensate): water soluble resin water reducing agent (sulfonated melamine formaldehyde resin, abbreviated as composite of melamine water reducer).
