Classification of fire protection grade of decoration materials. At present, there are mainly five grades of fireproof materials:
Class A: incombustible building materials, almost incombustible materials.
A 1: nonflammable, no open flame.
A2 level: non-combustible, and the smoke should be qualified.
B 1 grade: flame retardant building materials: flame retardant materials have good flame retardant effect. It is not easy to catch fire in the air or under the action of high temperature, and it is not easy to spread quickly. The combustion will stop immediately after the fire source is removed.
Class B2: Combustible building materials: Combustible materials have a certain flame retardant effect. When exposed to an open flame in the air or under the action of high temperature, it will catch fire immediately, which will easily lead to the spread of the fire, such as wooden pillars, wooden frames, wooden beams and wood.
Class B3: Flammable building materials, which have no flame retardant effect, are easy to burn and have great fire risk.
In addition, according to different standards, the classification of fireproof materials is also different:
Fire rating classification of decorative materials II. Classification of fire rating of wall materials
B 1: paper gypsum board, fiber gypsum board, cement particleboard, mineral wool board, cotton board, perlite board, flame-retardant plywood, flame-retardant medium-density fiberboard, flame-retardant plastic decorative board, flame-retardant double-sided particleboard, colorful paint, flame-retardant wall coating, flame-retardant granite-like decorative board, assembled magnesium oxychloride cement wallboard, flame-retardant glass fiber reinforced plastic flat board, PVC plastic wallboard, light and high-strength composite wallboard.
B2: all kinds of natural wood, artificial board, bamboo, paper decorative board, decorative veneer board, printed artificial board, plastic veneer decorative board, polyester decorative board, composite plastic decorative board, plastic fiberboard, plywood, plastic, non-woven fabric wall covering, wall cloth, composite wallpaper, natural material wallpaper, artificial leather, etc.
Classification of fire protection grade of decorative materials. Classification of fire protection grade of ground materials
B 1: rigid PVC plastic, cement particleboard, cement wood wool board, neoprene floor, etc.
B2: Semi-hard PVC plastic floor, PVC coiled floor, wood floor, PVC, etc.
Four, the classification of ceiling materials fire rating
B 1: paper gypsum board, fiber gypsum board, cement particleboard, mineral wool decorative sound-absorbing board, glass wool decorative sound-absorbing board, perlite decorative sound-absorbing board, flame-retardant plywood, flame-retardant medium density fiberboard, rock wool decorative board, flame-retardant wood, aluminum foil composite material, flame-retardant phenolic plywood, aluminum foil FRP composite material, etc.
Classification of fire rating of decorative materials V. Classification of fire rating of decorative fabrics
B 1: various flame-retardant fabrics, etc.
B2: pure wool decorative cloth, pure linen decorative cloth, and other flame-retardant fabrics.
Classification of fire protection grade of decorative materials. Classification of other decorative materials.
B 1: PVC plastic, phenolic plastic, polycarbonate plastic, PTFE plastic, melamine, urea-formaldehyde plastic, silicone plastic decorative profile, various fabrics with olefin end-capping, etc.
B2: Polyethylene, polypropylene, polyurethane, polystyrene, glass fiber reinforced plastic, chemical fiber fabric, wood products, etc.
What are the fireproof materials for decoration?
flameproof glass
Fire-proof glass has good light transmission, fire resistance, heat insulation and sound insulation. There are three kinds of common fire-proof glass: laminated composite fire-proof glass, wire-sandwiched fire-proof glass and hollow fire-proof glass. Fireproof glass is an important place for financial insurance, jewelry stores, books and archives, cultural relics and valuables collection, financial settlement and so on. Provide ideal fireproof materials for fire doors, windows and fire partitions of industrial and civil buildings with fire separation requirements.
fireproof paint
Fire-extinguishing coating is a special fire-retardant coating, which is a solvent-based coating composed of chlorinated rubber, paraffin wax and various fire-retardant additives. It has good fire resistance and is suitable for the surface of ordinary wires. Expansion in case of fire produces 200 mm thick foam, which is carbonized into a protective layer to isolate the fire source.
fireproof blocking material
The fireproof plugging material is used to plug various penetrations, such as various openings formed when cables, air ducts, oil pipes and natural gas pipes pass through the wall (warehouse) and floor (a). The cable bridge is divided into sections to prevent the fire from spreading through these openings and gaps. It has fireproof function and is convenient to install. It includes organic fireproof plugging material, inorganic fireproof plugging material and fireproof bag.
There are many fireproof partition materials on the market now, and the characteristics of each product are different. Everyone must pay attention to classification when shopping. In fact, it is Bian Xiao's classification of fire rating of decoration materials and related contents of decoration fire-proof materials. I hope the content of this article can help everyone.
