玻璃錶面的處理是為了清除錶面的覆層和污物,以改變其錶面活性,使之有利於潤濕和黏接。錶面處理的方法包括化學處理、塗層、機械處理等。


1)錶面塗布硅氧烷偶聯劑法


硅氧烷水解生成硅醇基,這些硅醇基和玻璃錶面的硅醇基可以形成氫鍵,也可以縮合為硅氧鍵從而形成牢固的化學縮合。


有機硅氧烷的另一端是有機基團,與油墨中的樹脂有良好的親合力甚至發生化學交聯使用時可將Q5%1硅烷偶聯劑乙醇溶液塗於被印刷玻璃錶面,


乾燥之後進行印把偶聯劑預先加到油墨中,印刷後自行擴散至被印錶面,加入量為墨量的1%-5%


2)脫脂法


脫脂用丙、甲乙清洗脫脂,或用三氯乙烯氣脂。用球取溶劑璃表行


3)浸泡法


用下述溶液室溫浸泡15-20min,也可以達到錶面處理的目的。鉻酸1份(或者50%重鉻鹼鈉水溶液蒸餾水濃硫酸100然後用蒸餾水洗凈,


80-93℃乾燥20-30mn。再用鹽酸處理除去錶面鈉離子可提高附著牢度。


4)機械處理


用細粉磨料進行輕度噴砂處理或用水磨砂紙進行水磨。
