style="text-indent:25px">達(dá)克羅涂層根據(jù)5級評定標(biāo)準(zhǔn)評定，≥3.5級為合格，檢查涂層的固化情況:工件烘烤之后進(jìn)行冷卻，然后在涂層表面滴一滴氨水。如果涂層固化的溫度是足夠的話，大約三秒之后氨水會(huì)轉(zhuǎn)變成淺黃色。達(dá)克羅設(shè)備需要周期性的維護(hù)才能保證正常的運(yùn)轉(zhuǎn)。在維護(hù)時(shí)要注意一些要點(diǎn)。達(dá)克羅設(shè)備需要周期性的維護(hù)才能保證正常的運(yùn)轉(zhuǎn)。在維護(hù)時(shí)要注意一些要點(diǎn)。涂覆機(jī)的主電機(jī)在運(yùn)行滿一千小時(shí)之后，需要為減速箱補(bǔ)充32號潤滑油，且達(dá)到三千小時(shí)的運(yùn)行時(shí)間之后要進(jìn)行更換。使用潤滑油的各個(gè)軸承每周都要向注油孔添一次油，使用潤滑脂的部位需要每隔一個(gè)月就檢查一次，如果不夠要及時(shí)補(bǔ)充。達(dá)克羅涂層的導(dǎo)電性能不好，這樣就不宜用于導(dǎo)電連接的零件，如電器的接地螺栓等。</p><div

style="text-indent:25px">目前使用達(dá)克羅技術(shù)成本是要比電鍍成本高一些，但是深入地進(jìn)行一下經(jīng)濟(jì)分析還是合算的。以熱浸鍍鋅為例，現(xiàn)市場加工價(jià)每噸1800元，用達(dá)克羅加工費(fèi)大致高20%~30%，但是熱浸鍍鋅件易氫脆，易變形，廢品率高達(dá)10%左右，如果把加工成本和材料成本放在一起，遠(yuǎn)遠(yuǎn)超過達(dá)克羅高出的加工費(fèi)了，對中小零件的加工費(fèi)達(dá)克羅要比電鍍鋅高30%~50%，但是達(dá)克羅涂復(fù)件的壽命要高出原電鍍件的三至五倍，甚至更多，不僅節(jié)省了大量的維修費(fèi)，也節(jié)省了大筆的材料費(fèi)。對于個(gè)別要求高的零件，如汽車、摩托車、航天航空，公路橋粱、電器電子等要求高的零件，電鍍技術(shù)是無法滿足的，只能用達(dá)克羅技術(shù)才能解決，這也就不存在加工費(fèi)互比的問題了，例如有些汽車零件達(dá)克羅涂復(fù)每公斤七、八元，一噸只要七、八千元，這是電鍍無法比擬的。達(dá)克羅涂覆的生產(chǎn)過程需要管控好工件的前處理。河北達(dá)克羅涂層價(jià)格</p><p
