class="box"><p>金屬發(fā)生電化學(xué)腐蝕的主要原因之一就是由于表面與電解質(zhì)溶液或潮濕的大氣接觸，產(chǎn)生各種腐蝕原電池。據(jù)此，可通過(guò)改變金屬表面狀態(tài)，使金屬表面與腐蝕環(huán)境隔離，本地氟鋯酸推薦，防止腐蝕的發(fā)生。目前，金屬鍍件的表面處理一般采用磷化、陶化或者鉻酸鹽轉(zhuǎn)化膜法等方法，磷化技術(shù)是面涂裝前金屬表面處理普遍采用的方法，由于磷化劑中含有大量的磷和氮，會(huì)給環(huán)境帶來(lái)嚴(yán)重的污染，磷化劑中含有的重金屬也會(huì)給人體造成長(zhǎng)久性傷害，另外，磷化槽液產(chǎn)生的大量殘?jiān)枰?*指定地方處理，均給生產(chǎn)帶來(lái)附加成本，鑒于上述問(wèn)題，迫切需要一種環(huán)保的，親環(huán)境親水性優(yōu)異的，具有良好成膜效果的水溶性金屬處理劑。 <p> 為了解決上述問(wèn)題，本發(fā)明的目的是提出一種酸性水洗硅烷處理劑，在金屬表面具有良好成膜效果，且不含磷、重金屬，更加環(huán)保。 </p> <p> 本發(fā)明為了解決上述問(wèn)題所采取的技術(shù)方案為：一種酸性水洗硅烷處理劑，按照重量份數(shù)，所述處理劑由1-9份硅烷偶聯(lián)劑、1-9份無(wú)水乙醇和55-90份水作為主劑，本地氟鋯酸推薦，以1-9份氟鋯酸和0.5-5份三乙醇胺作為輔劑，本地氟鋯酸推薦，并添加0.5-5份硝酸鈉作為促進(jìn)劑混合攪拌制得。 </p><div

鍍錫板是制作食品罐和飲料罐的重要原材料。隨著人們生活水平的提高，鍍錫板的需求量也在增加，在生產(chǎn)鍍錫板的過(guò)程中，帶鋼經(jīng)鍍錫、軟熔以后，為了提高鍍錫板的耐腐蝕性，防止鍍錫板在儲(chǔ)存或涂烤時(shí)錫層氧化發(fā)黃，同時(shí)提高鍍錫板的耐硫化變黑等性能，要對(duì)鍍錫板進(jìn)行鈍化處理。**常用的是采用鉻酸鹽陰極鈍化處理，所得到的鈍化膜很薄，耐蝕性能很好。但是鉻酸鹽中所含的六價(jià)鉻毒性很大，嚴(yán)重污染環(huán)境、危害人體健康。為了保護(hù)環(huán)境、保障人體健康，各國(guó)都在研究高耐蝕性、環(huán)保型無(wú)鉻鈍化工藝。

硅烷處理劑是一種由氟酸鋯(鹽)為主劑的前處理化學(xué)轉(zhuǎn)化膜技術(shù)，經(jīng)過(guò)硅烷處理后的金屬表面會(huì)形成一層納米級(jí)陶瓷轉(zhuǎn)化膜層。是一種新型的替代傳統(tǒng)磷化液換代產(chǎn)品。其在金屬基材表面沉積形成致密結(jié)構(gòu)的納米陶瓷轉(zhuǎn)化膜，阻隔性強(qiáng)，并與金屬氧化物形成強(qiáng)烈的結(jié)合力，與后續(xù)的有機(jī)涂層具有良好的附著力，能***提高金屬涂層的耐腐蝕性能，延長(zhǎng)耐蝕時(shí)間。 </p> <p> 硅烷處理劑總酸度為2.0～6.0，槽液濃度為3%～7%(可參考不同供應(yīng)商的產(chǎn)品系列參數(shù)要求)，pH值控制范圍為3.8～5.4;也可根據(jù)板材的材質(zhì)不同略作調(diào)整。硅烷處理劑在常溫下進(jìn)行處理，不需要加熱，可直接投入生產(chǎn)，也不需定期對(duì)熱交換器進(jìn)行清洗;無(wú)沉渣的運(yùn)輸和清理。 </p>
