涂(tu)裝(zhuang)生產流(liu)水(shui)線的(de)注意事項

一、涂(tu)(tu)裝(zhuang)(zhuang)生(sheng)產線上(shang)應注(zhu)意被涂(tu)(tu)物件(jian)的(de)裝(zhuang)(zhuang)掛(gua)。預先通過試浸來設計掛(gua)具(ju)及物件(jian)在涂(tu)(tu)裝(zhuang)(zhuang)生(sheng)產線上(shang)的(de)裝(zhuang)(zhuang)掛(gua)方式(shi)，保證(zheng)工件(jian)在浸涂(tu)(tu)時處于好的(de)位(wei)置。被涂(tu)(tu)物的(de)zui大平面應接近(jin)垂直，其他平面與水平呈10°-40°角，使余(yu)漆的(de)涂(tu)(tu)裝(zhuang)(zhuang)面上(shang)能夠較流暢地流盡(jin)。

二、在(zai)涂(tu)裝生產線上涂(tu)裝時為防止溶劑在(zai)車間內(nei)的擴散和塵埃落(luo)入漆槽內(nei)，噴漆涂(tu)裝流水線，浸漆槽應保護起來。

三、大(da)型(xing)物件在涂(tu)裝生產線上浸涂(tu)后，應待溶劑(ji)基本揮(hui)發后再送入烘(hong)房。

四、涂裝(zhuang)時要不(bu)斷(duan)注意涂料(liao)粘度(du)的(de)測(ce)定(ding)，涂裝(zhuang)流(liu)水線廠，每班應(ying)測(ce)定(ding)1-2次粘度(du)，若粘度(du)超(chao)過原粘度(du)的(de)10%，就應(ying)及時補加溶劑。添加溶劑時，應(ying)停(ting)止(zhi)浸涂作(zuo)業(ye)。攪(jiao)拌均(jun)勻后，測(ce)定(ding)粘度(du)，然(ran)后再繼續(xu)作(zuo)業(ye)。

五(wu)、漆(qi)膜(mo)的厚度主要決定于涂(tu)(tu)裝(zhuang)生產(chan)(chan)線(xian)上(shang)物體(ti)提(ti)(ti)升(sheng)的速率(lv)以及漆(qi)液的粘(zhan)度。在按(an)上(shang)述(shu)要求控(kong)制(zhi)了(le)漆(qi)液的粘(zhan)度后，涂(tu)(tu)裝(zhuang)生產(chan)(chan)線(xian)應按(an)照漆(qi)膜(mo)30um左右的zui大(da)限(xian)速度，根據不同的設備，實驗確(que)定合適(shi)的提(ti)(ti)升(sheng)速率(lv)。按(an)此速率(lv)均(jun)勻地(di)提(ti)(ti)升(sheng)被(bei)涂(tu)(tu)物件。提(ti)(ti)升(sheng)速率(lv)快，漆(qi)膜(mo)薄；提(ti)(ti)升(sheng)速率(lv)慢，漆(qi)膜(mo)厚且不均(jun)勻。
