塑封機日常保養注(zhu)意(yi)事項

1、環境(jing)(jing)對(dui)塑(su)(su)封(feng)(feng)(feng)的影(ying)響：塑(su)(su)封(feng)(feng)(feng)機(ji)(ji)預熱穩(wen)(wen)定(ding)(ding)時間受環境(jing)(jing)溫(wen)(wen)(wen)(wen)度(du)(du)(du)的影(ying)響, 環境(jing)(jing)溫(wen)(wen)(wen)(wen)度(du)(du)(du)高時, 塑(su)(su)封(feng)(feng)(feng)溫(wen)(wen)(wen)(wen)度(du)(du)(du)能(neng)較(jiao)快平(ping)衡穩(wen)(wen)定(ding)(ding)環境(jing)(jing)溫(wen)(wen)(wen)(wen)度(du)(du)(du)低(di)時, 散熱快,塑(su)(su)封(feng)(feng)(feng)溫(wen)(wen)(wen)(wen)度(du)(du)(du)需較(jiao)長(chang)時間才能(neng)達(da)到(dao)平(ping)衡穩(wen)(wen)定(ding)(ding)。切忌開機(ji)(ji)后(hou)溫(wen)(wen)(wen)(wen)度(du)(du)(du)顯示剛(gang)到(dao)塑(su)(su)封(feng)(feng)(feng)溫(wen)(wen)(wen)(wen)度(du)(du)(du)就進行塑(su)(su)封(feng)(feng)(feng), 因為(wei)此(ci)時塑(su)(su)封(feng)(feng)(feng)機(ji)(ji)膠(jiao)輥受熟尚未平(ping)衡穩(wen)(wen)定(ding)(ding), 只(zhi)是測(ce)溫(wen)(wen)(wen)(wen)點附(fu)近局部溫(wen)(wen)(wen)(wen)度(du)(du)(du)達(da)到(dao)塑(su)(su)封(feng)(feng)(feng)溫(wen)(wen)(wen)(wen)度(du)(du)(du)。一般(ban)來講預熱穩(wen)(wen)定(ding)(ding)時間不要短于20分鐘。塑(su)(su)封(feng)(feng)(feng)機(ji)(ji)工作(zuo)環境(jing)(jing)設計指標為(wei)一5~40℃ ,相(xiang)對(dui)濕度(du)(du)(du)不大于80%, 無腐(fu)蝕性(xing)氣體(ti)。因此(ci), 一般(ban)季(ji)節及氣候條(tiao)件(jian)下塑(su)(su)封(feng)(feng)(feng)機(ji)(ji)均(jun)能(neng)正常(chang)工作(zuo), 不會影(ying)響塑(su)(su)封(feng)(feng)(feng)效(xiao)果。

2、膠(jiao)輥(gun)(gun)硬度對塑封的影響塑封機膠(jiao)輥(gun)(gun)硬度為肖氏(shi)50度。若膠(jiao)輥(gun)(gun)因(yin)(yin)老化等原因(yin)(yin)引(yin)起變硬或開裂(lie)時, 將影響塑封質量, 會使過塑的證件塑封不牢, 需及時更換膠(jiao)輥(gun)(gun)。

3、塑(su)(su)(su)封(feng)(feng)質量(liang)檢查經塑(su)(su)(su)封(feng)(feng)后(hou)的(de)證件(jian)應(ying)透明、平整、塑(su)(su)(su)封(feng)(feng)套(tao)與卡芯應(ying)牢固封(feng)(feng)合(he)(he)為一體。夾(jia)(jia)層內(nei)無(wu)' 氣(qi)飽' , 無(wu)' 模糊(hu)白色印影' , 無(wu)油污、雜質等不良現象。常見的(de)幾種異常現象和(he)判斷發生的(de)原因, 如(ru)(ru)局部未封(feng)(feng)牢, 應(ying)考(kao)慮(lv)(lv)塑(su)(su)(su)封(feng)(feng)溫度偏低(di)如(ru)(ru)出(chu)現塑(su)(su)(su)封(feng)(feng)后(hou)證件(jian)變形起皺折, 應(ying)考(kao)慮(lv)(lv)為塑(su)(su)(su)封(feng)(feng)溫度過(guo)高或(huo)(huo)壓(ya)力太大如(ru)(ru)出(chu)現夾(jia)(jia)層內(nei)有氣(qi)泡或(huo)(huo)模糊(hu)白色印影, 應(ying)考(kao)慮(lv)(lv)為塑(su)(su)(su)封(feng)(feng)溫度不合(he)(he)適如(ru)(ru)出(chu)現塑(su)(su)(su)封(feng)(feng)過(guo)程中(zhong)粘合(he)(he)劑外(wai)溢(yi), 則應(ying)考(kao)慮(lv)(lv)為塑(su)(su)(su)封(feng)(feng)溫度過(guo)高或(huo)(huo)壓(ya)力太大。
