Interior decoration design and construction must be implemented in accordance with this regulation.  

The special field in "GB50222-2017 Code for Fire Design of Building Interior Decoration" (hereinafter referred to as the code) includes: fire hydrants in civil buildings and industrial buildings Space, evacuation passages and safety exit foyers, ceilings and walls of exits, atriums, horse corridors, stairs, etc. connecting the upper and lower floors inside the building. 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 are places where fire safety is under key supervision, which is related to the public safety, life and property safety of the majority of people. The materials used are strictly regulated in the new specification.

Most of the ceilings, walls, and floors of public buildings in civil buildings must use Class A decoration materials, and most of the ceilings of multi-storey and high-rise buildings require Class A decoration materials must be used, and others must be B1 and decoration materials. In the description of the specification provisions, 3 Classification and classification of decoration materials Table 1 "Example of Classification of Combustion Performance of Commonly Used Building Interior Decoration Materials" in the "Classification of Combustion Performance of Commonly Used Building Interior Decoration Materials" The materials used for each part of the combustion grade A grade are: granite, marble, Terrazzo, cement products, concrete products, gypsum boards, lime products, clay products, glass, tiles, mosaics, steel, aluminum-copper alloys, natural stone, metal composite boards, fiber gypsum boards, glass magnesium boards, silicon-calcium boards, etc.

There is a big difference between the above materials and the current situation that a large number of latex paints are used as decoration materials on the ceiling, wall and floor of the building. Can the paint be used in a single layer? Inside a multi-storey civil building? how to choose? How to use it with the base material to meet the requirements in the new specification?

 Combustion performance grades of decoration materials in various parts of single-storey and multi-storey civil buildings

Whether the base material meets the A-level standard: 3 Classification and classification of decoration materials in the description of the specification provisions 1 Commonly used building interior decoration materials In the example of combustion performance grade classification, the materials used for combustion grade A grade are: granite, marble, terrazzo, cement products, concrete products, gypsum boards, lime products, clay products, glass, ceramic tiles, mosaics, steel, aluminum and copper Alloy, natural stone, metal composite board, fiber gypsum board, glass magnesium board, silicon calcium board, etc.

Among them, Article 3.  0.6 expresses: Inorganic decoration coatings applied on A-level substrates can be used as A-level decoration materials. Applied on Class A substrates, organic decoration coatings with a wet coverage ratio of less than 1.5KG/M² and a dry film thickness of no more than 1.0mm can be used as Class B1 decoration materials.

That is, the use of inorganic coatings on these A-level substrates can meet the A-level fire protection requirements, using organic coatings and wet coating coverage The ratio is less than 1.5KG/M², and the dry film thickness of the coating is not greater than 1.0mm, which can meet the fire protection requirements of Class B1.

This is the same as before the implementation of the new regulations, most of the buildings including special places, civil buildings, factory buildings and warehouses all use organic paint latex There is a very big difference in the situation of lacquer, real stone paint, texture paint or other types of paint. Inorganic coatings, which were not commonly used in the past, have occupied a particularly important position in the new 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. focuses on the production, development, sales and service of STUCCO facing mortar. Among its six categories of products, dry powder finishing mortar, dry powder inorganic coating, water-based inorganic coating, modern rammed earth, and fair-faced concrete finishing materials all belong to inorganic coatings, that is, the combustion class A in the new specification, and meet the requirements The combination of Class A base materials can meet the fire protection requirements of Class A non-combustible grades, including 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.  

Many of the above-mentioned inorganic coatings of Simon United Building Materials Co., Ltd. not only meet the Class A non-combustible rating, but also have a variety of different The texture effect color can meet the requirements of the new national standard for fire prevention and meet the pursuit of the architect designer for the decorative effect.
