随着我国社会经济的快速发展,特别是近两年来电子、生物、医药等高新技术的迅猛发展,洁净室在各种制造业中得到了广泛的应用。洁净室主体结构为彩钢夹芯板,现阶段仍是洁净室不可替代的产品。然而,洁净室彩钢板的防火等级越来越受到政府有关部门和制造业的重视。

新标准《洁净厂房设计规范》(gb50073-2001)中洁净室的屋面板、墙板(含夹层材料)应为不燃材料,不得使用有机复合材料。屋顶的耐火极限不应小于0.4h,疏散走廊屋顶的耐火极限不应小于1.0h,隔墙及其相应屋顶的耐火极限不应小于1.0h。新标准对洁净室彩钢板提出了更高的要求。
但从现阶段国内洁净室建设来看,部分企业仍在使用禁用的有机夹芯材料,如聚苯乙烯、聚氨酯等,以减少项目投资。从目前的观点来看,在减少投资的同时,也会增加你的风险。洁净室与其他厂房有本质区别。这是一座相对密闭的厂房。如果发生火灾事故,夹芯材料的有毒气体不易消除,直接影响人体健康。我们呼吁在你建造洁净室之前要考虑到“安全”。
With the rapid development of social economy in China, especially the rapid growth of high and new technologies such as electronics, biology and medicine in recent two years, clean rooms are widely used in various manufacturing industries. The main structure
of the clean room is the color steel sandwich board, which is still a product that can not be replaced by the clean room at this stage. However, the fire protection grade of color steel plate in clean room has attracted more and more attention from
relevant government departments and manufacturing industries.

The roof and wall panels (including sandwich materials) of clean rooms in the new standard GB50073-2001 Code for Design of Clean Workshops should be non-combustible
and organic composite materials should not be used. The fire resistance limit of the roof should not be less than 0.4h, the fire resistance limit of the roof of the evacuation corridor should not be less than 1.0h, and the fire resistance limit of
the partition wall and its corresponding roof should not be less than 1.0h. With the implementation of the new standards, higher requirements have been put forward for the clean room color steel plate.

However, from the
point of view of domestic clean room construction at this stage, some enterprises still use prohibited organic sandwich materials, such as polystyrene, polyurethane and so on, in order to reduce project investment. From a current point of view, while
reducing investment, it increases your risk. Clean room is essentially different from other factory buildings. It is a relatively airtight factory building. If there is a fire accident, the toxic gases of sandwich materials can not be easily eliminated,
which directly affects human health. We call for "safety" to be taken into account before you build clean rooms.
