塑封機(ji)日(ri)常保養注意事項

1、環(huan)(huan)(huan)境對(dui)塑(su)(su)封(feng)的(de)影響(xiang)：塑(su)(su)封(feng)機預熱(re)(re)穩(wen)定(ding)時間受環(huan)(huan)(huan)境溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)的(de)影響(xiang), 環(huan)(huan)(huan)境溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)高時, 塑(su)(su)封(feng)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)能較(jiao)(jiao)快平衡穩(wen)定(ding)環(huan)(huan)(huan)境溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)低時, 散(san)熱(re)(re)快,塑(su)(su)封(feng)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)需較(jiao)(jiao)長時間才能達(da)到(dao)平衡穩(wen)定(ding)。切(qie)忌(ji)開機后溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)顯(xian)示剛到(dao)塑(su)(su)封(feng)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)就進行塑(su)(su)封(feng), 因為此時塑(su)(su)封(feng)機膠(jiao)輥受熟(shu)尚未平衡穩(wen)定(ding), 只是測溫(wen)(wen)(wen)(wen)(wen)點附近局部溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)達(da)到(dao)塑(su)(su)封(feng)溫(wen)(wen)(wen)(wen)(wen)度(du)(du)(du)(du)(du)。一般來講預熱(re)(re)穩(wen)定(ding)時間不(bu)(bu)要短于20分鐘。塑(su)(su)封(feng)機工作環(huan)(huan)(huan)境設計指(zhi)標為一5~40℃ ,相對(dui)濕度(du)(du)(du)(du)(du)不(bu)(bu)大(da)于80%, 無腐蝕性氣體(ti)。因此, 一般季(ji)節及氣候(hou)條(tiao)件下(xia)塑(su)(su)封(feng)機均能正常工作, 不(bu)(bu)會影響(xiang)塑(su)(su)封(feng)效(xiao)果。

2、膠輥硬度對(dui)塑(su)封的(de)影(ying)響(xiang)塑(su)封機膠輥硬度為肖氏50度。若膠輥因老化等原因引起變硬或開裂(lie)時(shi), 將影(ying)響(xiang)塑(su)封質(zhi)量, 會使過塑(su)的(de)證件(jian)塑(su)封不牢, 需及時(shi)更換(huan)膠輥。

3、塑(su)封(feng)(feng)(feng)(feng)質量檢查經(jing)塑(su)封(feng)(feng)(feng)(feng)后(hou)的證件應(ying)(ying)透明、平整、塑(su)封(feng)(feng)(feng)(feng)套與卡(ka)芯應(ying)(ying)牢固封(feng)(feng)(feng)(feng)合(he)為(wei)一體。夾層內無' 氣飽(bao)' , 無' 模糊(hu)白色印影(ying)' , 無油污、雜質等不良現(xian)象。常見的幾(ji)種異常現(xian)象和判斷發生的原(yuan)因, 如局(ju)部(bu)未封(feng)(feng)(feng)(feng)牢, 應(ying)(ying)考(kao)慮(lv)塑(su)封(feng)(feng)(feng)(feng)溫(wen)度(du)偏低如出(chu)(chu)(chu)現(xian)塑(su)封(feng)(feng)(feng)(feng)后(hou)證件變形起(qi)皺(zhou)折, 應(ying)(ying)考(kao)慮(lv)為(wei)塑(su)封(feng)(feng)(feng)(feng)溫(wen)度(du)過(guo)高或(huo)(huo)壓力(li)(li)太(tai)大(da)如出(chu)(chu)(chu)現(xian)夾層內有氣泡(pao)或(huo)(huo)模糊(hu)白色印影(ying), 應(ying)(ying)考(kao)慮(lv)為(wei)塑(su)封(feng)(feng)(feng)(feng)溫(wen)度(du)不合(he)適(shi)如出(chu)(chu)(chu)現(xian)塑(su)封(feng)(feng)(feng)(feng)過(guo)程中粘合(he)劑外溢, 則應(ying)(ying)考(kao)慮(lv)為(wei)塑(su)封(feng)(feng)(feng)(feng)溫(wen)度(du)過(guo)高或(huo)(huo)壓力(li)(li)太(tai)大(da)。
