How to choose ceiling, wall and floor coatings that meet the national standard GB50222-2017 for factory buildings and warehouses

08 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.  


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.


Factory buildings and warehouses are the key places for fire safety supervision, which are 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 factory buildings and warehouses must use grade A decoration materials. In the description of the specification, 3 Classification and classification of decoration materials 1 “Example of classification of combustion performance of commonly used building interior decoration materials” The materials of the parts are: granite, marble, terrazzo, cement products, concrete products, gypsum boards, lime products, clay products, glass, ceramic tiles, mosaics, steel, aluminum-copper alloys, natural stone, metal composite panels, Fiber gypsum board, glass magnesium board, silicon calcium board, etc.


The above materials are very different from the current situation where 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 special places? ? how to choose? How to use it with the base material to meet the requirements in the new specification?

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


Article 3.  0.6 states: Finishing materials use . Applied on Class A substrates, the organic decoration coating 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 a Class B1 decoration material.


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


Before the implementation of the new regulations, most buildings including special places, civil buildings, factory buildings and warehouses all use organic latex paint on the ceiling and walls 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. Dry powder finishing mortar, dry powder inorganic coating, water-based inorganic coating, modern rammed earth, and fair-faced concrete finishing materials in its six major categories of products are all inorganic coatings, that is, the combustion class A in the new specification, which meets 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 from Simon United Building Materials Co., Ltd. not only meet the Class A non-combustible rating, but also have A variety of different texture effects and colors can meet the fire protection requirements of the new national standard and meet the pursuit of decorative effects by architects and designers.
