不銹鋼板鍍膜產(chǎn)生影響的的因素:
一、不銹鋼板的內(nèi)在因素,我們都知道的是不銹鋼中鎳含量低下,不銹鋼的鈍化性能就低,所以不銹鋼中馬氏體含量和鉻跟鎳的含量對(duì)不銹鋼板表面的鈍化性能影響很大。
三、不銹鋼板的表面清潔度。對(duì)于不銹鋼合金來說,不銹鋼的表面越光滑粗糙度越低,那么該不銹鋼表面就越難有異物附著上,異物不易附著,那么對(duì)不銹鋼表面的腐蝕也就降到了*低點(diǎn),所以不銹鋼表面要盡量采用精加工的表面。另外不銹鋼板的*后的鈍化后的清洗也應(yīng)該認(rèn)真進(jìn)行,這樣才能使殘余的酸液促進(jìn)陽極反應(yīng),保護(hù)膜層的完整性,保證不銹鋼板的表面的耐腐蝕性增強(qiáng)。
二、不銹鋼板使用環(huán)境中的介質(zhì),不銹鋼的鈍化膜在熱力學(xué)中是屬于受抑制的亞穩(wěn)態(tài)架構(gòu),它所發(fā)揮的保護(hù)作用于所處的環(huán)境中的介質(zhì)有關(guān)。但是不論在哪種環(huán)境中使用,在使用的過程中,都要對(duì)不銹鋼板進(jìn)行定期的清洗來除去不銹鋼板表面附著的有害物質(zhì)。
四、 氯離子,氯離子對(duì)不銹鋼板鍍膜的危害是極大的,所以,我們?cè)趯?duì)不銹鋼板的表面進(jìn)行鈍化過程中要嚴(yán)格控制鈍化液中的氯離子的含量,基于氯離子對(duì)不銹鋼板的危害性。很多鈍化用化學(xué)材料對(duì)氯離子都有著限量的要求,在配置鈍化液用水和清洗用水也對(duì)氯離子有著嚴(yán)格的水質(zhì)要求,來保證鈍化成品中不含有氯離子。
