我司是專門致力于金屬表面處理的高科技企業(yè),成立于1999年。
公司現(xiàn)有四條全自動(dòng)磷化加工流水線。
主要業(yè)務(wù)是錳系磷化加工,錳系黑色磷化加工,鋅系磷化加工等。
已經(jīng)通過了ISO9001-2008,TS16949國際質(zhì)量體系認(rèn)證。
公司已經(jīng)掌握新型的磷化加工工藝技術(shù)以及四套先進(jìn)的流水線設(shè)備,能夠?yàn)閺V大客戶提供優(yōu)質(zhì)的服務(wù)。
公司坐落于上海寶山經(jīng)濟(jì)開發(fā)區(qū),交通便利,物流方便快捷。
汽車零部件,標(biāo)準(zhǔn)件,液壓件,閥體,石油機(jī)械這些工件采用磷化處理的很多,使用廣泛.
因?yàn)榱谆け容^薄,不對(duì)工件尺寸產(chǎn)生影響,和力學(xué)性能。與傳統(tǒng)的高溫發(fā)黑相比具有很大優(yōu)勢(shì).
高溫發(fā)黑耗能大且不環(huán)保,防腐性能很差。鹽霧時(shí)間只有幾個(gè)小時(shí)。
更嚴(yán)重的是發(fā)黑前使用強(qiáng)酸去除氧化皮。對(duì)于傳統(tǒng)的高溫發(fā)黑工藝存在的問題,可以采用氧化的方法去除工件的氧化皮。
通過幾年的實(shí)踐證明這種方法是有效的可行的,并且贏得了很好的經(jīng)濟(jì)效果,尤其是緊固件經(jīng)過磷化處理后,對(duì)其不受任何影響。磷化膜質(zhì)量可靠,防腐性能強(qiáng)。
所謂的表調(diào)用專業(yè)的術(shù)語來講就是表面調(diào)整,是把工件放入裝有表調(diào)液的槽子里進(jìn)行表面調(diào)整處理的過程。
有人說我們的磷化液不需要表調(diào),也可以做的很好,其實(shí)這種說法是完全錯(cuò)誤的。
表面調(diào)整可以去除除油,酸洗而造成的零件表面不均勻。
可以促進(jìn)零件表層的活力,還能形成大量極細(xì)的結(jié)晶層,加快磷化膜的形成。
使磷化膜更細(xì)膩,膜細(xì)致均衡,膜層光滑。
還能避免磷酸鐵,優(yōu)化了涂裝的附著力,而且還能改變磷化膜的防腐性能,耐磨。
改善磷化性能,能減少磷化時(shí)間,減少一半時(shí)間,降低磷化的溫度條件。
改變工件的材質(zhì),有些工件含有許多的石墨成分,這些石墨在磷化的時(shí)候散開成很多的部分。即使它對(duì)磷化反應(yīng)很有幫助,但是磷化出來的磷化膜很不勻稱。
細(xì)膩性很差,但通過表調(diào)后,磷化效果很好。
減少成本,主要是可以降低磷化液的消耗,表面調(diào)整和磷化的溫度有關(guān)系。
就是磷化溫度低,上海磷化加工表調(diào)的作用就明顯,磷化效果就好。
Auto parts, standard parts, hydraulic parts, body, oil machinery these workpiece using phosphating a lot of, is widely used. Because the phosphating film is thin, no workpiece size effect,上海磷化 and mechanical properties. Compared with traditional high temperature nigrescence has a great advantage.
High temperature nigrescence energy consumption and environmental protection, corrosion performance is very poor. Salt fog time only a few hours.
More serious is the use of 上海酸洗磷化處理strong acid remove black oxide skin. As for traditional high temperature nigrescence process existing problems, can上海酸洗磷化加工 use oxidation method to remove the oxide skin.
Through several years of上海黑色磷化加工 practice proves上海錳系磷化加工廠家 this method is effective feasible, and won the good economic effects, especially fasteners after phosphating, the has no effect. Phosphate coating quality is reliable, corrosion performance is strong.
The so-called table call professional terminology is surface adjustment, is the piece into a table adjustable liquid trough in the processing of the adjustment of the surface.
Some say our phosphating solution don't need table to move, can also do very well, actually this kind of view is completely wrong. Surface adjustment can remove grease, pickling and cause of parts surface uneven. |
