防火板材要注意哪些细节问题?

  防火板材在建筑工程上施工也有许多技术,其中有两点应特别注意:
  Fire prevention board on the architectural engineering construction also has a lot of technology, there are two points should pay special attention to:
  1.关于防火板施工的嵌缝材料。用于该产品的嵌缝材料应具有一定的柔性和膨胀性能,以防止板材拉缝。这种嵌缝材料不准配制,成本也不高,就由板材生产厂供货或提供配方。
  1. Sealing of fire prevention board construction materials. Sealing material for this product should have a certain flexibility and performance, in order to prevent the plate seam. The sealing material are not allowed to make, the cost is not high also, is provided by the board manufacturer supply or formula.
  2.固定板材的钉子一定进行除锈处理,或用不锈钢钉。海外有的直接规定,玻镁防火板施工所用的钉子必须是不锈钢钉。
  2. The fixed plate nails must be derusting processing, or use the stainless steel nail. Some overseas direct regulation, glass magnesium nails must be stainless steel used in the construction of fire prevention board.
  因为在玻镁防火板中存在氯盐,氯盐对铁的腐蚀世人皆知,中国不少用防火板的工程经一年多就在埋入的钉头上表面出现锈斑,再经一段时间锈斑就会鼓成包块。但质环境越潮湿,这个问题暴露的越早,要避免这个弊病的发生,必须保证钉子不被锈蚀。
  Because in glass magnesium fire board exist chlorine salt, chlorine salt corrosion of iron well known, China with a lot of fire prevention board project by more than a year on the surface of the nail on the head that flush rust spots, rusty spot again after a period of time will drum into bag piece. But mass environment more damp, the earlier the problem exposed, to avoid the happening of the disease, must ensure that the nails are not rust.
