Ngati filimu yoteteza imagawidwa molingana ndi kuchuluka kwa ntchito, imatha kugawidwa m'magawo osiyanasiyana: zitsulo zopangidwa ndi zitsulo, pulasitiki yopangidwa ndi pulasitiki, zinthu zamagetsi zamagetsi, zitsulo zopangidwa ndi zitsulo, chizindikiro chapamwamba, galimoto Pamwamba pa chinthucho. , mankhwala pamwamba pa mbiri ndi pamwamba pa zinthu zina.

Kugwiritsa ntchito zinthu zinayi zotsatirazi zoteteza filimu:

1. Kanema woteteza wopangidwa ndi zinthu za pp:

Filimu yotetezayi iyenera kuti idawonekera kale pamsika.Dzina la mankhwala likhoza kutchedwa polypropylene, chifukwa liribe mphamvu zowonetsera, choncho liyenera kumamatira kwa ilo, ndipo mutatha kuling'amba, Padzakhalabe zomatira pamwamba pa chinsalu.Ngati zitenga nthawi yayitali, zingayambitsenso dzimbiri pazenera, motero sizigwiritsidwanso ntchito.

2. Kanema woteteza wopangidwa ndi zinthu za pvc:

Mbali yayikulu ya filimu yoteteza ya pvc iyenera kukhala kuti mawonekedwe ake ndi ofewa komanso osavuta kuyika.Komabe, filimu yotetezayi ndi yolemetsa kwambiri ndipo kufalikira kwake sikwabwino kwambiri.Chophimba chonsecho chidzakhala chosamveka komanso chovunda.Chophimba chakumbuyo chidzakhalanso chosindikizidwa, chifukwa chidzasintha pakapita nthawi, kotero moyo wautumiki ndi waufupi kwambiri.

3. Kanema woteteza wopangidwa ndi zinthu za pe:

Zinthu za filimu yotetezayi makamaka LLDPE, ndipo zinthuzo zimasinthasintha ndipo zimakhala ndi mphamvu yotambasula.Makulidwe abwinobwino amasungidwa pakati pa 0.05mm-0.15mm.Kukhuthala kumatsimikiziridwa molingana ndi zomwe makasitomala amafuna M'malo mwake, filimu yoteteza yopangidwa ndi zinthu za pe imathanso kugawidwa makamaka: filimu ya anilox ndi filimu ya electrostatic.

Pakati pawo, filimu ya electrostatic makamaka imagwiritsa ntchito magetsi osasunthika kuti itenge mphamvu yomatira.Sichifuna guluu aliyense, choncho ndi ofooka mu mamasukidwe akayendedwe.Nthawi zambiri amagwiritsidwa ntchito poteteza pamwamba pa zinthu monga electroplating;pamene filimu ya anilox ili ndi ma meshes ambiri pamwamba.Mtundu uwu wa filimu yotetezera imakhala ndi mpweya wabwino, ndipo zotsatira zomatira ndizokongola kwambiri.Chinthu chachikulu ndi chakuti ndi lathyathyathya kwambiri ndipo alibe thovu.

Chachinayi, filimu yoteteza zinthu za opp:

Ngati muyang'ana kuchokera ku maonekedwe okha, filimuyi yotetezayi ndi yofanana ndi chiweto, komanso ndi yaikulu kwambiri mu kuuma, ndipo imakhala ndi ntchito yolepheretsa moto, koma zotsatira za phala lonse ndizochepa kwambiri, choncho ndizovuta kwambiri. kumsika.Sikovuta kuona kugwiritsa ntchito filimu yotetezayi.

M'malo mwake, pali mitundu yambiri yamakanema oteteza omwe amatha kugawidwa malinga ndi kugwiritsidwa ntchito.Mwachitsanzo, pali mafilimu oteteza magalimoto, mafilimu osungira chakudya, zinthu za digito, ndi mafilimu oteteza nyumba.Zidazo zimasinthidwanso pang'onopang'ono kuchokera ku pp yapitayi. Zapangidwa kuti zikhale zotchuka kwambiri pa msika, ndondomeko yonse yachitukuko ikadali yayitali, kotero idzayanjidwa ndi ambiri amsika.
