Q: What is the upper temperature limit for refractory materials?: The key depends on what refractories you use

Q: What are the electrical fire protection materials?: Flame retardant organic resin: They can be classied into PVC, vinyl chloride, chlorinated rubber, epoxy resin emulsion, epoxy resin, phenolic resin, etc.. Fire retardant additive: Phosphorus and halogens, nitrogen organic compounds (chlorinated paraffin, tributyl phosphate (TBP) and polybrominated diphenyl ethers) and boron (boric acid, zinc borate, boric acid aluminum), antimony, aluminum, zirconium inorganic compounds.

Q: What is the strength of high strength refractory material?: Refers to constrcuting through ramming, and a refractory materials that is hardened in temperature higher than normal. mixed through a certain grade of refractory aggregate, powder, binder, additives, water or other liquids. Can be classified into high alumina and fireclay, magnesite, dolomite, zirconium and silicon carbide by the standard of texture.

Q: How to divide the fire rating standards of insulation materials?: 1. According to the GB8624-97 national standard, building materials can be divided into following levels in terms of combustion performance. A-level: Non-combustible building materials: Materials almost don't burn. B1-level: Fire-retardant building materials: Fire-retardant materials are good at resisting flame. It is difficult for them to burst into fire when coming across open fire in the air or at high temperature. It will not quickly get wilder and when the fire source removes, it will be extinguished immediately. B2-level: Combustible building materials: Combustible building materials can play a certain role in preventing combustion. It will immediately burst into flames when coming across open fire or at high temperature, and will lead to fire spreading, such as wooden pillars, roof frames and beams as well as stairs. B3-level: Inflammable building materials: Inflammable building materials are highly flammable with no flame retardant ability. The fire risk is high. 2.The exterior wall thermal insulation materials can be classified according to fire rating. 1. Insulation materials with A-level combustion performance: rock wool, glass wool, foam glass, ceramic foam, foam cement, close-celled perlite, etc. 2. The insulation materials with B1-level combustion performance: specially-treated extruded polystyrene boards(XPS)/ specially-treated Polyurethane(PU), Phenolics, Polystyrene rubber powdery particles,etc. 3. Insulation materials with B2-level combustion performance: Expanded polystyrene sheets(EPS), Extruded polystyrene board(XPS), Polyurethane(PU), Polyethylene(PE), etc.

Q: How to choose thermal insulation materials for flood heating?: 1, Select the appropriate floor material suitable for radiant floor heating. The floor radiant heating system mainly transfer heat through the ground concrete and the ground material to the room. Therefore in the heating season the ground material will always be heated during heating season. Therefore, it is better to choose stone materials and compround floor plate insensitive to tenmperature change with good heat dissipation and functions. Currently, wood floor is not suitable for the ground radiant heating system. 2, choose the pipe with anti permeability performance. Plastic floor heating pipe itself has a certain air permeability, if oxygen penetrates in it is prone to oxygen erosion and system's mental device will be eroded, resulting in the risk of leakage. Therefore in order to ensure the reliable operation of the heating system, the selected pipe must have anti oxygen permeation performance, and meet the standard stipulated by the DIN4726 oxygen permeation quantity: and be less than 0.1mg\L.d at 40 C.

Q: Refractory factory grinding brick dust harmful to the body?: Inhalation of this dust can affect people's respiratory tract for a long time

Q: What's the B grade fireproofing material?: B1 grade ceiling material: gypsum board, fobrous plasterboard, cement particle board, mineral wool decorative acoustic panels, glass wool decorative acoustic board, perlite decorative acoustic board, flame retardant plywood, flame retardant medium density fiberboard, rock wool decorative sheet, flame retardant wood, aluminum foil composites, flame retardant phenolic laminate, aluminum foil glass fiber reinforced plastic composite material, etc.; B1 grade wall material: gypsum board, fibrous plasterboard, cement particle board, mineral wool board, glass wool board, perlite board, flame retardant plywood and medium density fiberboard, fireproof plastic decorative sheet, nonflammable double-sided particle board, multicolor coating, flame retardant wallpaper and wall cloth, flame retardant simulated granite decorative plates, magnesium oxychloride cement prefabricated wall panels, flame retardant glass fiber reinforced plastic plates, PVC plastic clapboards, high-strength and lightweight composite wallboards, fire-retardant molded wooden composite boards, flame retardant colored artificial boards, nonflammable glass fiber reinforced plastics, etc.

Q: What does refractory mean?: What is refractory material?Refractory material generally refers to the inorganic refractory degree over 1580oC non metallic materials. It includes natural ore and various products in accordance with certain requirements after a certain process. With the volume stability of high temperature mechanical properties, a good, is the necessary equipment for all kinds of high temperature materials.

Q: Who knows the highest temperature the high-temperature refractory coating can resist?: When coating the fire-resistant coating on a steel beam of a building, paint film thickness reaching 2mm, and steel beams in the building are on fire, the fire-resistant coating can withstand for two hours. Fire-resistant coating is passive fire protection materials painted on the surface of the protected objects (eg. steel structure) , which can be divided into types of thick, thin, ultra-thin and facing according to the thickness. It can be divided into water-based and solvent-based products by medium. Whatever the structure of the building is, it will collapse if it is on fire for a long time. Fire-resistant coating function as isolation layer on the surfaces of the protected objects, delaying the building collapse time to win over valuable time for rescue and fire fighting. I hope this answer can help you.

Q: Who knows about the types of Dalian thermal insulating and refractory materials?: (1) rock wool board: the heat conductivity coefficient is 0.041-0.045. It is fire retardant, has a great temperature absorption while a poor thermal insulation performance. (2) glass wool: it is simple in construction and free in cutting. It has advantages of antibiosis, mould proof, aging resistance and anticorrosion, and can ensure a healthy environment. It has a low hygroscopicity and a stable physical property. (3) expanding polystyrene board(EPS board): thermal conductivity: 0.037-0.041, it has a good thermal insulation performance, cheap price but a poor intensity. (4) extruded polystyrene board(XPS board): thermal conductivity: 0.028-0.03, it has a better thermal insulation performance, high intensity, moisture resistance while it is expensive, and requires surface treatments during construction. (5) gelatine powder polyphenyl granule heat insulating slurry: heat conductivity coefficient: 0.057-0.06, it has a good flame resistance while a poor thermal insulation performance, as well as has high construction requirements and can be recycled. (6) polyurethane foam: heat conductivity coefficient: 0.025-0.028, it has advantages of waterproofness, thermal insulation, high intensity, high integrity, and good integrity, but it has a poor fireproof?performance and is more expensive. (7) rigid polyurethane: heat conductivity coefficient: 0.018-0.023, it has advantages of low heat conductivity coefficient and good thermal performance. When the unit weight of rigid polyurethane is 35 to 40kg per cubic meters, it is equivalent to half of the EPS. It is the one with the lowest heat conductivity coefficient among all the thermal insulation materials. (8) perlite slurry: heat conductivity coefficient: 0.07-0.09, it has advantages of fire and high-temperature resistance, and high water absorption but is poor in thermal insulation.
