Fireproof material grade fire board material which

For home safety and elimination of fire hazards, more and more families have chosen to use fireproof panels, fireproof panels themselves, and have good fire and heat insulation properties. So, how is the grade of fireproof material divided? What are the fire board materials? Let's take a look with Xiaobian.

Fireproof material grade

China's national standard GB8624-97 has a very clear specification for the fire-resistant grade of decoration materials and is divided into the following levels:

Class A: Non-combustible decoration materials

Class B1: Flame-retardant decoration materials

Class B2: Flammable decoration materials

Class B3: Flammable decoration materials

Refractory Grade of Decoration Materials - Class A: Part A materials such as granite, concrete products, terrazzo, cement products, gypsum board, marble, lime products, clay products, glass, steel, ceramic tile, aluminum, copper alloys, mosaics, etc. .

Decoration material fire resistance grade - B1 level: Part B1 materials such as fiberboard, cement particle board, mineral wool decorative acoustic board, glass wool decorative acoustic board, paper plaster board, perlite decorative sound-absorbing board, flame retardant Plywood, fire-retardant wallpaper, colorful paint, fire-retardant medium-density fiberboard, rock wool decorative board, fire-resistant wood, aluminum foil composite materials, flame-retardant phenolic plywood, aluminum foil, glass fiber reinforced plastic composite materials, inflammable wall cloth, etc.

Decoration material fire resistance grade - B2 level: B2 grade materials such as pure wool decorative cloth, PVC coil floor, wooden floor vinyl carpet, semi-rigid PVC plastic floor, pure hemp decorative cloth, flame retardant other fabrics Wait.

What are the fire board materials?

Fireproof panels are fireproof building materials for surface decoration and are widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, and exterior walls. The fire prevention board is the impregnation process of melamine and phenolic resin in the base paper (titanium powder paper, kraft paper), and is formed under high temperature and high pressure.

1, mineral wool board, glass wool board: mainly mineral wool, glass wool insulation material. It is inherently incombustible, with good high temperature resistance and light weight. Now, most of the plates have evolved into inorganic-bonded materials, and mineral wool and glass wool are used as reinforcing materials.

2. Cement board: The board has high strength and a wide range of sources. In the past, it was often used as a fire suspended ceiling and partition wall, but its fire resistance was poor. The thermal insulation and sound insulation properties of cement concrete components are good, and can be used as partition walls and roof panels.

3. Perlite plate, floating bead plate, slate plate: It has the characteristics of light weight, high strength, good toughness, fire insulation, and convenient construction. It can be widely used in high-rise buildings, sub-rooms, households, bathrooms, kitchens, and communications. Tubes and other non-load bearing parts.

4. Fireproof gypsum board: The main components of the board are non-flammable and contain water of crystallization. The fireproof performance is good and can be used as partition walls, ceilings and roof panels. It has lighter weight, can reduce the weight of the building, and is easy to process, can be sawed and planed, convenient construction, and good decorative, but its poor anti-folding performance.

5. Calcium Silicate Fiberboard: It has characteristics of light weight, high strength, good heat insulation and durability, excellent processing performance and construction performance, etc. It is mainly used for making ceilings, partition walls, and fire protection materials for steel columns and steel beams. .

6、Magnesium oxychloride fireproof board: It is a kind of magnesium oxychloride cement products, with magnesia cementitious material as main body, glass fiber cloth as reinforcement material, light heat preservation material as filler compound, and it can meet the requirements of non-combustibility. A new type of environmentally friendly sheet.

The above information about fireproof material grades and fireproof board materials is briefly introduced here, and we hope to help you. For more information, please visit this website. Stay tuned.
