今天我在这里跟大家谈谈与我们香港的消防化学关系最密切的事情。聚苯乙烯泡沫塑料。非常荣幸的是,继竹子和安全网之后,聚苯乙烯泡沫塑料成为香港火灾的重要原因。有人说,火灾之所以如此严重,是因为他们使用了非法聚苯乙烯泡沫塑料。然后我就想,有没有竹子可以燃烧呢?安全网安全与否只是树木的问题,无关紧要,只能跟着节奏。无需解释。一看就消失了,火箭烧煤了!但聚苯乙烯泡沫塑料确实击中了我的手。今天我就和大家聊聊保丽龙是否存在违规和合规问题。国内泡沫橡胶主要分为B1、B2、B3三个等级。 B1的全称是B1阻燃泡沫橡胶,B2的全称是B2阻燃泡沫橡胶,B3称为B3泡沫橡胶。这三个都是合法合规的泡沫。没有任何证据表明一个是合规的,另一个是非法的。这三个是根据燃烧特性重新分类。 The requirements of the B1 flame retardant are that it is difficult to ignite an open flame, self-ignites when removed from the flame, and produces less toxic gas when burned. The flame retardant required by B2 is that it can ignite when encountering a fire source but the intensity of the fire is small, and it will self-extinguish within 1 second after leaving the fire. B3遇明火燃烧并放出有毒气体。 The components of B1 flame retardant foam mainly include polymer materials (such as polyurethane, polyimide), expansion agents, flame retardants and otherauxiliary verbs.聚氨酯是B1级阻燃泡沫的主要成分之一。具有良好的粘合性、弹性和密封性能,并能形成稳定的泡沫结构。 Polyimide, another possible polymer material, has excellent high temperature resistance and fire retardant properties, which can improve the overall fire protection effect of f奥姆橡胶。阻燃剂主要是无机阻燃剂,如氢氧化铝、氢氧化镁等,同时释放出的水还能起到隔热、阻隔热量的作用,从而有效防止燃烧。还有有机阻燃剂,如含卤素的有机化合物(四溴邻苯二甲酸酐、四溴双酚A等),燃烧时能释放大量自由基,从而阻止火的燃烧,达到阻燃的目的。我不是要说膨胀剂,是发泡剂。 B2阻燃泡沫的成分主要包括聚氨酯预聚物、发泡剂、催化剂和阻燃剂。 As the main component of B2 flame retardant foam, polyurethane prepolymer provides the main structure and elasticity of the material. It is a prepolymer produced by the reaction of polyol and isocyanate, and has excellent adhesion and sealing properties.这东西燃烧得有点,但不是太高。离火后会自溶,但也会释放出一些有毒气体。阻燃剂其实和B1很相似,也分为无机和有机两大类。 B3泡沫的成分与B2泡沫相同。不同的是B3不需要添加阻燃剂或只需要添加少量阻燃剂。这三种类型的泡沫塑料用于不同的领域。例如,B3聚苯乙烯泡沫塑料用作纸箱的内部填充物。搬家公司都可以使用,而且合法合规。如果您搬家时有重要物品,则需要一份纸箱清单。如果您单独搬家,专业搬家公司会在纸箱内放入泡沫。这通常是 B3,您不太可能获得 B2 或 B1。但B3严禁用于建筑行业。上海静安火灾后,国家出台新规定,全国适用oard. All B3 materials are not allowed to be used even in temporary construction. Therefore, in addition to moving, -iimpake and gluing, B3 is now used for outdoor art design, sculpture and rockery. Both B2 and B1 can be used in the construction industry.细节更加复杂。让我做一个简单的区分。 B2 is generally not allowed to be used in permanent buildings. If you are doing exterior wall insulation or interior decoration, you need and can only use B1.但对于临时建筑,比如户外音乐节,搭建棚子、舞台等,符合条件的可以使用B2。 The detailed situation is too complicated to describe.简单来说,B2只能用在一些临时建筑上,而B1则基本可以用在所有的地方。 Therefore, if the fire in Hong Kong was indeed fueled by styrofoam, it could only be B2 or B3. Howevern, these two are absolutely not allowed to be used in the construction of external wall insulation a以及在中国的维修项目。 However, I don't know what the Hong Kong construction regulations stipulate.毕竟,竹脚手架在中国已经很长时间不被允许使用了。中国不是用的吗?最后,有人说阻燃泡沫塑料比易燃泡沫塑料更贵。有的说贵十倍以上,有的说贵几十倍。这种观点是绝对错误的。我在上面贴出了它们的活性成分。 B2和B3的有效成分是一样的,区别在于加了多少火?至于阻燃剂,看成分就知道,价格并不高。也就是说,B2和B3的成分相同,但B2含有更多的阻燃剂,所以B2比B3贵一点,但也贵不了多少。如果有大批量促销,可能会比B3便宜。 B1实际上比B2更贵,尤其是在中国发布新规定之后。 B1是严格的德马建筑行业的价格较高,但其价格主要受产能限制,供大于求,因此价格昂贵。 The raw materials of B3 are chemical scraps, which are limited by chemical production capacity, so the price fluctuates.但近年来,全国房地产行业整体表现不佳,因此建筑行业对B1的需求也有所减少。近年来B1的价格有所下降。 If you buy less, it is mawill be twice as expensive. If you buy in bulk, I estimate that a bottle costs only a few cents. All three types of foaming agents are sold at Bao Bao.下面我贴的截图都是截图。您也可以自己搜索。 Basically, the way fire turns has nothing to do with Styrofoam. B1 Flame-Retardant Styrofoam is useless on gasoline. On the other hand, it can also slow down the fire and buy time to escape. But I don't know what exactly is used in this construction project in香港。毕竟,这是人们长期以来争论竹子能否阻燃的领域。 特别声明:以上内容(如有则包括图片或视频)由自媒体平台“网易号”用户上传发布。本平台仅提供信息存储服务。注:以上内容(包括图片、视频,如有)由网易HAO用户上传发布,网易HAO为社交媒体平台,仅提供信息存储服务。
