技术介绍
在钢丝/带热镀锌
中,为了提高钢丝/带的抗腐蚀性能,通常需要对钢丝 /带表面进行镀锌处理,即在钢丝/带的表面覆盖一层金属锌。镀锌操作的一般过程如下(1)、先用碱性液体对钢丝/带进行碱洗,再用清水清 洗掉钢丝/带表面的碱洗液体;(2)、然后再用酸性液体对钢丝/带进行酸洗,再用清水洗 掉粘附在钢丝/带表面的酸性液体;(3)、然后再在钢丝/带的表面浸涂氯化铵助镀剂,烘 干后,使钢丝/带连续经过熔化有锌液的锌锅内,对钢丝/带进行镀锌。传统的镀锌方式是将常温的钢丝/带直接进入锌液后镀锌,其主要存在如下缺 陷(1)纯铁锌锅通常为常开式的,由于锌的凝固温度为421°C,因此,为了保证正常的镀锌 过程,锌液的温度应该维持在445°C、60°C,为此需要有足够高的温度来加热锌锅,这样一 方面浪费能源,另一方面又会使锅体更容易受到腐蚀而损坏。(2)、由于刚进入锌液的钢丝 /带温度远低于锌液温度,钢丝/带周围的锌液突然受冷降温,会在钢丝/带表面凝结锌 ...
