温材料防火等级划分
温材料防火等级划分
Classification of Fire Protection Grade for Thermal Materials
建筑材料的燃烧性能分为以下几种等级：
The combustion performance of building materials can be divided into the following grades:
A级(不燃性建筑材料)：几乎不燃烧的A级保温材料。
Class A (non-combustible building materials): Class A thermal insulation materials that are almost non-combustible.
B1级(难燃性建筑材料)：难燃类材料有较好的阻燃作用。其在空气中遇明火或在高温作用下难起火，不易很快发生蔓延。
Class B1 (Flammable Building Material): Flammable materials have better flame retardant effect. It is difficult to catch fire in the air or under the action of high temperature, so it is not easy to spread quickly.
B2级(可燃性建筑材料)：可燃类材料有一定的阻燃作用。在空气中遇明火或在高温作用下会立即起火燃烧，易导致火灾的蔓延，如木柱、木屋架、木梁、木楼梯等。
Class B2 (flammable building materials): Flammable materials have a certain flame retardant effect. When www.jinggaimoju.net.cn www.hupomoju.com.cn www.biaozhizhuang.net.cn www.jianchajing.org.cn www.shipindai.net.cn exposed to open fire in the air or under the action of high temperature, it will ignite immediately, which will easily lead to the spread of fire, such as wooden columns, wooden roof trusses, wooden beams, wooden staircases and so on.
B3级(易燃性建筑材料)：无任何阻燃效果，极易燃烧，火灾危险性很大。
Level B3 (Flammable Building Materials): No flame retardant effect, extremely flammable, fire risk is very high.
毋庸置疑，保温设计过程中防火性能更好、保温性能出色的系统将更能赢得市场的认可。
There is no doubt that the system with better fireproof performance and excellent thermal insulation performance in the process of thermal insulation design will win more market recognition.
