彩涂板在焊接时由于外界的因素有时会出现气泡现象，这一现象的产生会使得焊接不牢固而且还影响美观程度，所以我们在焊接时要尽量的去避免这种情况，那么导致这一现象的原因是什么呢?只有找到原因才可以更好的解决它。下面给大家讲解一下。
因为彩涂板在生产制造中对各工序开展严控，在外型，耐用度和工艺性能层面确保具备匀称的品质。批量生产的彩涂板价格廉价，与制成品件镀层解决法对比，建筑涂料中的液体成分含水量高，有机化学建筑涂料耗损低，经济发展上划算。应用彩涂板可大大简化制作工艺，且找不到因有机化学解决上漆和烤制等所导致的空气污染。通常选用的建筑涂料类型有环氧树脂，聚脂，硅改性材料聚脂，聚偏氟乙稀，聚氨酯材料等。

锌的熔点为419.5℃，化学性质生动，在常温下的空气中，外表生成一层薄而致密的碱式碳酸锌膜，可阻止进一步氧化。当温度到达225℃后，锌猛烈氧化，呈现白色的氧化锌。高温烧烤后镀锌板外表防腐层物质遭到氧化，因而镀锌板不能耐高温，加热外表会变颜色，或外表有防护性的其它物质氧化后容易变黄。 镀锌卷板外表应除去油污或蜡质成分及其它污渍或粉尘，这样能够进步原子灰的附着力;

1、冷热轧钢板通过碱洗脱脂，并水洗，烘干后再进入有辐射管加热的卧式（立式）加热炉进行退火，炉内通入一定的氢气使炉内早层还原气氛。 2、加热到一定温度的钢带在一定的条件下浸入锌液内进行热镀锌。 3、锌花大小有液态锌的成分来控制的同时，采用强制冷却的方法来控制，小锌花产品在锌花开始扩散之前，用小锌花设备进行急冷防止锌液继续扩散，形成小锌花。 4、经热镀锌后的待岗冷却后通过表面光整，最后根据用途，分别进行表面钝化处理或直接生产成彩涂卷板。
