style="text-indent:25px">鍍鋅六角螺栓就是在普通的六角螺栓的基礎(chǔ)上再經(jīng)過(guò)酸洗、脫脂、助鍍劑等工藝的處理，經(jīng)過(guò)這些工藝流程后，它比普通的六角螺栓更耐用，防銹性能更強(qiáng)，韌性更高。不過(guò)在經(jīng)過(guò)鍍鋅之后，它的螺紋擰合會(huì)變得難度增加，想要解決這個(gè)問(wèn)題，可以在螺栓進(jìn)行鍍鋅之后回攻，從而留出一定的間隙。不過(guò)回攻也會(huì)破壞掉螺栓螺紋表面的鍍層，導(dǎo)致里面的材料暴露，影響螺栓的耐腐蝕性能，這就難免導(dǎo)致加工的精度下降。很多螺栓生產(chǎn)廠家希望從鍍鋅工藝上面進(jìn)行考慮，看看是否可以很好的改善擰和難度大的問(wèn)題，比如調(diào)整浸鍍的時(shí)間和溫度，但是從嘗試的結(jié)果來(lái)看并不理想。</p><p
