style="text-indent:25px">達(dá)克羅處理按涂履方式不同分為浸涂甩干、噴涂、刷涂等幾種方法。在決定選用哪種方式時，首先要考慮的是要覆蓋在工件上的涂層是注重功能性還是裝飾性，還要考慮涂層厚度的控制、生產(chǎn)速度、產(chǎn)品形狀和所要求的質(zhì)量。浸涂甩干：適用于標(biāo)準(zhǔn)件和其它小的工件。工件一般要浸液10～?20s，為使Cr6+在鋼鐵基材上充分形成鈍化膜；離心甩干時應(yīng)該正轉(zhuǎn)反轉(zhuǎn)各兩次，每次10～20s。對于特殊件要用夾具，難甩的零件要用人工輔助，比如用棒在離心筐中攪一下，將筐中的工件的位置變化一下，使積存在角落里的涂液能被順利甩離工件。甩液機(jī)的轉(zhuǎn)速要適當(dāng)，太快太慢都不利，總之是要保證零件上不能有積液、掛液、氣泡、漏涂等。通過多次正反轉(zhuǎn)甩液、多次調(diào)整甩干速度，根據(jù)實際上的涂覆效果來確定工件的加入量、甩液機(jī)的轉(zhuǎn)速、轉(zhuǎn)動的時間等工藝參數(shù)。丹陽達(dá)克羅企業(yè)當(dāng)達(dá)克羅涂層較厚時，會因為涂層固化前不易流平或工件形狀的原因造成甩干時涂膜不均勻。</p><div

style="text-indent:25px">表面達(dá)克羅處理的鎖緊墊圈在使用過程中出現(xiàn)生銹問題的原因是：在緊固件選型過程中沒有考慮到碳鋼達(dá)克羅涂層和不銹鋼的電位差較大，再加上使用環(huán)境惡劣，有水介質(zhì)存在，造成腐蝕加速。考慮到鎖緊墊圈的使用環(huán)境較惡劣（室外），根據(jù)電偶腐蝕原理，同一機(jī)構(gòu)中應(yīng)盡可能用同一種金屬，或者電位盡可能接近的兩種金屬，并用絕緣物使之隔開，避免產(chǎn)生電偶腐蝕。因此，確定采用不銹鋼A4的鎖緊墊圈替代彈簧鋼墊圈。達(dá)克羅是目前表面處理使用比較多的，另外氧化、磷化也挺多。達(dá)克羅在溫度35℃±2℃、濕度95%條件下，經(jīng)過10個周期240小時循環(huán)試驗，達(dá)克羅加工涂層表面無變化。四川達(dá)克羅的價格</p><p
