　　昆山(shan)(shan)環(huan)氧(yang)地(di)(di)(di)坪漆(qi)(qi)是在昆山(shan)(shan)地(di)(di)(di)區(qu)使用(yong)的(de)比較多的(de)裝(zhuang)飾材料(liao)。然而當想(xiang)要去除(chu)昆山(shan)(shan)環(huan)氧(yang)地(di)(di)(di)坪漆(qi)(qi)時卻是一件讓人頭痛(tong)的(de)事(shi)，如果直接鏟掉，會損壞地(di)(di)(di)質。所以只(zhi)能(neng)夠讓杭(hang)州環(huan)氧(yang)地(di)(di)(di)坪漆(qi)(qi)消除(chu)。結合環(huan)氧(yang)地(di)(di)(di)坪漆(qi)(qi)的(de)特性，專家發現了堿(jian)液可以去除(chu)這種漆(qi)(qi)，于(yu)是研究出了堿(jian)液去除(chu)昆山(shan)(shan)環(huan)氧(yang)地(di)(di)(di)坪漆(qi)(qi)法(fa)。

　　堿(jian)(jian)液(ye)(ye)除昆山環氧地坪(ping)漆(qi)(qi)法是利用(yong)(yong)堿(jian)(jian)液(ye)(ye)的腐(fu)蝕(shi)作用(yong)(yong)，使舊涂膜(mo)(mo)(mo)膨脹(zhang)(zhang)松(song)軟，從而達(da)到除去舊漆(qi)(qi)的目的。堿(jian)(jian)液(ye)(ye)脫漆(qi)(qi)劑是液(ye)(ye)體(ti)或膏狀物質，脫漆(qi)(qi)時，用(yong)(yong)刷(shua)子將(jiang)堿(jian)(jian)液(ye)(ye)涂于舊涂膜(mo)(mo)(mo)上，經過數小時，涂膜(mo)(mo)(mo)膨脹(zhang)(zhang)松(song)軟后，用(yong)(yong)刮(gua)刀(dao)或刮(gua)鏟將(jiang)鼓起涂膜(mo)(mo)(mo)鏟除，并用(yong)(yong)溫水洗凈采用(yong)(yong)堿(jian)(jian)液(ye)(ye)脫漆(qi)(qi)。這種堿(jian)(jian)液(ye)(ye)脫漆(qi)(qi)劑成(cheng)本低，生產比較(jiao)安全，對人(ren)體(ti)影響較(jiao)小。

         堿(jian)液除昆山環氧(yang)地坪(ping)漆法的缺點(dian)是：脫漆時(shi)間(jian)要求較長，一般需經過(guo)數小時(shi)。堿(jian)液法脫漆處理會造(zao)成過(guo)度(du)腐蝕，運用時(shi)應引起注意。
