   热浸锌就是将除锈后的钢构件浸入600℃左右高温融化的锌液中,使净化板表面附着锌层,锌层厚度对5mm以下薄板不得小于65μm,对厚板不小于86μm,从而起到防腐蚀的目的。这种方法的优点是耐久年限长,生产工业化程度高,质量稳定。因而被大量用于受大气腐蚀较严重且不易维修的室外彩钢板广东11选5走势图中。如大量输电塔、通讯塔等。近年来大量出现的轻钢结构体系中的压型钢板等,也较多采用热浸锌防腐蚀。热浸锌的首道工序是酸洗除锈,然后是清洗。这两道工序不彻底均会给防腐蚀留下隐患,所以必须处理彻底。对于净化板结构设计者,应该避免设计出具有相贴合面的构件,以免贴合面的缝隙中酸洗不彻底或酸液洗不净。造成镀锌表面流黄水的现象。热浸锌是在高温下进行的。对于管形构件应该让其两端开敞。若两端封闭会造成管内空气膨胀而使封头板爆裂,从而造成安全事故通不畅,易在管内积存。

   这是一种与热浸锌防腐蚀效果相当的长效防腐蚀方法。具体做法是先对贵州净化板表面作喷砂除锈,使其表面露出金属光泽并打毛。再用乙炔-氧焰将不断送出的铝(锌)丝融化,并用压缩空气吹附到彩钢板表面,以形成蜂窝状的铝(锌)喷涂层(厚度约80μm-100μm)。最后用环氧树脂或氯丁橡胶漆等涂料填充毛细孔,以形成复合涂层。此法无法在管状构件的内壁施工,因而管状构件两端必须做气密性封闭,以使内壁不会腐蚀。这种工艺的优点是对构件尺寸适应性强,构件形状尺寸几乎不受限制。大到如葛洲坝的船闸也是用这种方法施工的。另一个优点则是这种工艺的热影响是局部的,受约束的,因而不会产生热变形。与热浸锌相比,这种方法的工业化程度较低,喷砂喷铝(锌)的劳动强度化影响。
