What kind of coating meets the non-combustible grade of Class A decoration materials in the fire protection code for interior decoration design of new buildings?

06 2018

GB50222-2017 Code for Fire Protection Design of Building Interior Decoration was announced on July 31, 2017, and was officially implemented on April 1, 2018. Implement in accordance with this regulation.

 

Materials that produce a lot of smoke or toxic gases when burned are safe and adaptable, advanced technology, and economical and reasonable.

 

This is the general basis for choosing materials and the fundamental basis for choosing paint. Whether the material meets the new national standard is a necessary condition to ensure the safety of the interior decoration of the building.

 

In the specification, different places are strictly divided and defined, and the fire rating of materials used in different places is specified. strict regulations. All kinds of buildings include “special places, civil buildings, factory warehouses”

 

Special places: civil buildings and industries The fire hydrant space in the building, the evacuation passage and the safety exit hall, the ceiling and wall of the exit, the atrium, the corridor, the stairs connecting the upper and lower floors inside the building, etc. Windowless room, fire water pump room, power distribution room and other ancillary equipment spaces. Restaurant, scientific research laboratory, warehouse and storage room. Exhibition places and places specified in other regulations.

 

Civil buildings: including single-storey, multi-storey and high-rise civil buildings, covering all spaces of public commercial buildings, residences and other buildings Auxiliary facility space

 

Factory warehouse: single-storey, multi-storey Class A, B and C factory buildings, Class A, B, C, D and E warehouses. That covers all factories and warehouses.

 

The decoration materials used in these three types of buildings are divided into: ceiling decoration materials, wall decoration materials, floor decoration materials, partition decoration Materials, fixed furniture, upholstery fabrics, and other decoration and decoration materials.

 

Closely combined with architectural coatings are: ceiling decoration materials, wall decoration materials, and floor decoration materials.

 

And in Article 3.0.2, the combustion performance level of decoration materials is stipulated.

 


Ceilings and walls in special places must meet Class A standards. The walls of public places basically must use Class A standard materials, others must use Class B1 standard materials, and some must use Class A standard materials. The ceiling and walls of underground civil buildings must use Class A standard materials. The factory buildings and warehouses are located in the D-V factory buildings and warehouses, and the others must use Class A standard materials.

 

3 Classification and classification of decoration materials in the description of the specification provisions Table 1 Combustion performance grades of commonly used building interior decoration materials In the classification example, Class A combustion grade uses the following materials: Granite, marble, terrazzo, cement products, concrete products, gypsum boards, lime products, clay products, glass, ceramic tiles, Mosaic, steel, aluminum-copper alloy, natural stone, metal composite board, fiber gypsum board, glass magnesium board, silicon calcium board, etc.

 

Article 3.0.6 states: the Used as a grade A decoration material. Applied on Class A substrates, the wet coating coverage ratio is less than 1.5KG/M², and the dry film thickness of the coating is not more than 1.0mmOrganic decoration coatings can be regarded as Class B1 The decoration materials are used.

 

That is, on these A-grade substratesuse Inorganic coatings can meet the requirements of Class A fire protection, and organic coatings and the wet coating coverage ratio is less than 1.5KG/M², and the dry film thickness of the coating is not more than 1.0mm can reach the B1 level fire protection requirements.

 

, The ceiling and walls of the factory building and warehouse are all made of organic paint latex paint, real stone paint, texture paint or other types of paint. standards, which do not meet the requirements of the new specification. Inorganic coatings, which were not commonly used in the past, have already occupied a particularly important position in the national standard, and are the materials that must be used for most building interior decoration. Otherwise, it cannot pass the fire inspection and acceptance, and if a fire occurs, it must be strictly held accountable.

 

 

Shenzhen Simon United Building Materials Co., Ltd. Serve. Among its six categories of productsdry powder finishing mortar, dry powder inorganic coating, water-based inorganic coating, modern rammed earth, fair-faced concrete finishing materials are all inorganic coatings, that is, the combustion grade A in the new specification, which meets the requirements In special places, civil buildings, warehouses and other places that require the use of Class A non-combustible materials. As a pioneer of dry powder inorganic coatings, Simon has truly achieved leadership in product technology and service.

 

The above-mentioned inorganic coatings of Simon United Building Materials Co., Ltd. not only meet the Class A non-combustible level , and there are a variety of different texture effects and colors, which can satisfy the pursuit of architects and designers for decorative effects while meeting the fire protection requirements of the new national standard.
