防火板材需要注意的两大事项

1.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。
1 fixed plate nail must derusted, or stainless steel nail. Overseas some direct regulation, glass magnesium fire plate construction with nails must be stainless steel nails.
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 the chlorine salt in a glass magnesium fireproof board, chloride salts of iron corrosion is known to the world, many Chinese used fireproof board engineering after more than one year is in buried nail head surface rust, the rust will drum for a period of time into mass. But the more humid environment, the more exposed the problem, to avoid the occurrence of this disease, it is necessary to ensure that the nails are not corroded.

2.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。
2 on the construction of fire prevention board caulking material. For caulking materials of the product should be flexible and expansive property, in order to prevent the plate gap. The sealing materials are not allowed to be prepared, the cost is not high, supply or provide formula by plate production plant.
