fire accident

53 people have been killed and 70 are being treated in hospitals. 17 of them are seriously injured.

In the media interview, Major General Zhu Liping, deputy director of the Fire Department of the Ministry of public security, who rushed to the scene to direct fire rescue and accident investigation, said clearly that "nylon nets, bamboo strips and insulation materials polyurethane foam used for decoration are inflammable, especially polyurethane foam. Once burned, a poisonous gas containing toxic hydrogen cyanide will be generated. If people breathe in it, they will die of poisoning."

It is learnt that building insulation is essential because of the internal gas self circulation system required by high-rise buildings.

At present, most of the insulation materials used in high-rise buildings in China are mostly polymer foam insulation boards, such as polyurethane (PU), molded polystyrene foam board (EPS), extruded polystyrene foam board (XPS) and so on.

According to statistics, only 90% of the high-rise building insulation materials in Beijing are all these high polymer foam insulation boards.

In February 9, 2009, the fire broke out in the Central Television Taipei distribution building. It was because the fireworks ignited the insulation material XPS in the north building structure, and then spread rapidly, eventually igniting the whole building. In 2008, Shenzhen District Dance Club of Shenzhen, in the "9. 20" fire, due to the extensive use of polyurethane material decoration, the performance personnel used the prop gun to ignite the ceiling polyurethane material, and the July 2, 2007 Peking University table tennis hall fire was also caused by the ignition of the thermal insulation material.

According to expert identification, this kind of thermal insulation board has low thermal conductivity, good material density and compressive strength, but the drawback is that its flame retardancy is very poor, its burning speed is fast, and droplets will be produced during the process, which will easily cause the fire to accelerate.

Moreover, more toxic gases will be generated during combustion, especially carbon monoxide (CO).

Fire fighting in high-rise buildings has always been a worldwide problem. This incident once again sounded the alarm for us.

With the continuous occurrence of similar events, the flame retardancy of wall insulation materials has become a new topic.

According to the experts, it has special properties such as flame retardant, heat insulation, sound insulation, and so on.

textile

At present, it has been gradually applied to many fields of industrial construction, and has effectively undertaken the important role of related engineering construction.

At present, industrial textiles enterprises have already entered the field of wall insulation and thermal insulation materials, and the performance of products has been able to meet the needs of engineering applications. However, due to the high production costs and the lack of market awareness, the promotion of products has been restricted, and the flame-retardant building textiles still have a good market space.

It is also hoped that relevant departments of the state will strengthen supervision and management of the standards and construction codes for building textiles and protect the interests of the public.
