彩涂板焊接時(shí)會(huì)出現(xiàn)氣泡的原因

彩涂板焊接時(shí)會(huì)出現(xiàn)氣泡的原因

彩涂板在焊接時(shí)由于外界的因素有時(shí)會(huì)出現(xiàn)氣泡現(xiàn)象,這一現(xiàn)象的產(chǎn)生會(huì)使得焊接不牢固而且還影響美觀(guān)程度,所以我們?cè)诤附訒r(shí)要盡量的去避免這種情況,那么導(dǎo)致這一現(xiàn)象的原因是什么呢?只有找到原因才可以更好的解決它。下面給大家講解一下。

鍍鋅卷板是否耐高溫

鋅的熔點(diǎn)為419.5℃,化學(xué)性質(zhì)生動(dòng),在常溫下的空氣中,外表生成一層薄而致密的堿式碳酸鋅膜,可阻止進(jìn)一步氧化。當(dāng)溫度到達(dá)225℃后,鋅猛烈氧化,呈現(xiàn)白色的氧化鋅。高溫?zé)竞箦冧\板外表防腐層物質(zhì)遭到氧化,因而鍍鋅板不能耐高溫,加熱外表會(huì)變顏色,或外表有防護(hù)性的其它物質(zhì)氧化后容易變黃。   鍍鋅卷板外表應(yīng)除去油污或蠟質(zhì)成分及其它污漬或粉塵,這樣能夠進(jìn)步原子灰的附著力;

鍍鋅卷板的工藝流程

1、冷熱軋鋼板通過(guò)堿洗脫脂,并水洗,烘干后再進(jìn)入有輻射管加熱的臥式(立式)加熱爐進(jìn)行退火,爐內(nèi)通入一定的氫氣使?fàn)t內(nèi)早層還原氣氛。   2、加熱到一定溫度的鋼帶在一定的條件下浸入鋅液內(nèi)進(jìn)行熱鍍鋅。   3、鋅花大小有液態(tài)鋅的成分來(lái)控制的同時(shí),采用強(qiáng)制冷卻的方法來(lái)控制,小鋅花產(chǎn)品在鋅花開(kāi)始擴(kuò)散之前,用小鋅花設(shè)備進(jìn)行急冷防止鋅液繼續(xù)擴(kuò)散,形成小鋅花。   4、經(jīng)熱鍍鋅后的待崗冷卻后通過(guò)表面光整,最后根據(jù)用途,分別進(jìn)行表面鈍化處理或直接生產(chǎn)成彩涂卷板。
