外墙保温资料防火等级

Fire Protection Grade of External Wall Insulation Data

外墙保温资料防火等级次要有以下几种:

The fire protection grade of exterior wall thermal insulation materials should be as follows:

A级爲不燃资料爲:WW无机活性墙体保温隔热资料、水泥发泡保温板、玻化微珠保温砂浆、岩棉板、玻璃棉板、发泡陶瓷等。

Class A is non-flammable data: WW inorganic active wall insulation materials, cement foam insulation board, vitrified bead insulation mortar, rock wool board, glass wool board, foamed ceramics, etc.

A级爲不燃资料具有密度小、热导率低、承压才能较高、施工方便、经济耐用等特点,普遍用作热管道、热设备及其他工业管道设备和工业修建上的保温绝热资料及工业与民用修建围护构造的保温、隔热、吸声资料。因其热波动性好,多用做钢构造的耐火维护被覆资料。

Class A non-combustible materials have the characteristics of low density, low thermal conductivity, high pressure capacity, convenient construction and economic durability. They are widely used as thermal insulation materials for heat pipes, thermal equipment and other industrial pipeline equipment and industrial construction, as well as thermal insulation, thermal insulation and sound absorption materials for industrial and civil construction envelopes. Because of its good thermal fluctuation, it is often used as the refractory maintenance cover material for steel structures.

A1级防火保温材料

B1级爲难燃资料,大多爲无机资料,添加较少量的阻燃剂,如聚苯板、挤塑板、酚醛板、聚氨酯板等。

Class B1 is flame retardant material, mostly inorganic material, adding a small amount of flame retardants, such as polyphenyl board, extrusion board, phenolic board, polyurethane board, etc.

熄灭功能:是指资料和(或)制品遇火熄灭时所发作的一切物理和(或)化学变化,也就是对火反响特性。资料对火反响特性,反映了火灾初始阶段的状况,次要包括:不燃性,着火(点着)性,火焰蔓延性等。我国采用ISO/TC92制定的对火反响实验办法规范。

Extinguishing function: refers to all physical and/or chemical changes that occur when data and/or products are extinguished by fire, i.e. fire response characteristics. The response characteristics of data to fire reflect the condition of the initial stage of fire. Secondly, it includes: non-flammability, ignition (ignition), flame spread and so on. Our country adopts ISO/TC92 standard for fire response experiment.

国际岩棉板市场中岩棉板,酚醛板,复合岩棉板,泡沫玻璃板也是事先中国普遍消费的产品。随着我国关于岩棉板,酚醛板,泡沫玻璃板的研发任务不时进步,岩棉板在旧楼创新,修建项目上的运用量宏大所以很小的价钱差别也会变成很大的本钱。

In the international rock wool board market, rock wool board, phenolic board, composite rock wool board and foam glass plate are products that are widely consumed in China. As China's research and development tasks on rock wool board, phenolic foam board and foam glass board have been progresses from time to time, the use of rock wool board in the old building innovation and construction projects is huge, so the small price difference will become a great capital.

B2级爲可阻燃资料,也称爲阻燃资料,多爲无机保温资料,添加过量的阻燃剂。

Class B2 is flame retardant material, also known as flame retardant material, mostly inorganic heat preservation material, adding excessive flame retardant.

可阻燃资料具有的或资料经处置后具有的分明推延火焰蔓延的性质。

The property of flame retardant data or data disposed of to clearly postpone flame spread.
