Filimu yotambasula, yomwe imadziwikanso kuti filimu yotambasula ndi filimu yochepetsera kutentha, idapangidwa koyamba ku China pogwiritsa ntchito PVC ngati maziko ndi DOA ngati pulasitiki komanso zomatira zokha za filimu yotambasula ya PVC. Chifukwa cha zovuta zachilengedwe, mtengo wokwera (wokhudzana ndi PE, malo ocheperako onyamula pa unit) komanso kusasunthika kosasunthika, filimu yotambasula ya PE idachotsedwa pomwe kupanga kwapakhomo kudayamba mu 1994-1995. Zomwe zimayambira ndi LLDPE, kuphatikiza C4, C6, C8 ndi metallocene PE (MPE).
Fectures
Amapangidwa pogwiritsa ntchito utomoni wa LLDPE wotumizidwa kunja ndi tackifier zowonjezera zowonjezera molingana, ndipo amatha kupanga filimu yozungulira yogwira ntchito pamanja, makina amtundu wokana, makina amtundu wa pre-stretch, anti-UV, anti-static and anti- dzimbiri. Ili ndi zabwino izi:
1. Pogwiritsa ntchito zida zapawiri-wosanjikiza co-extrusion, filimu yokhotakhota yoponderezedwa imatha kukulitsa mawonekedwe a polima iliyonse, kuwonekera kwake, kulimba kwamphamvu, ndi kukana kwa perforation, kufika pamlingo woyenera kwambiri pakusungunuka.
2. Imakhala ndi mphamvu zolimba, zowonekera bwino, komanso makulidwe ofanana.
3. Imakhala ndi kutalika kwautali, kupirira bwino, kukana kung'ambika kopingasa, komanso zomata zodzimatira.
4. Ndi chilengedwe wochezeka recyclable zinthu, zoipa, sanali poizoni, akhoza mwachindunji mmatumba chakudya.
5. amatha kupanga zomatira za mbali imodzi, kuchepetsa phokoso lomwe limaperekedwa panthawi yokhotakhota ndi kutambasula, kuchepetsa fumbi ndi mchenga poyendetsa ndi kusunga.
Kugwiritsa ntchito
1. Zosindikizidwa zosindikizidwa
Kupaka kwamtunduwu kumakhala kofanana ndi kutsitsa filimuyo, pomwe filimuyo imakutidwa ndi mphasa kuti ikulungire zonse, ndiyeno zida ziwiri zotenthetsera kutentha zimasindikiza filimuyo mbali zonse ziwiri. Uwu ndiye filimu yoyambilira yomwe imagwiritsidwa ntchito ndipo yapangitsa kuti pakhale mitundu ina yambiri yamapaketi.
2. Kuyika kwathunthu m'lifupi
Kupaka kwamtunduwu kumafuna kuti filimuyi ikhale yokwanira kuti iphimbe mphasa, yomwe imakhala ndi mawonekedwe okhazikika, choncho ndi yoyenera kugwiritsidwa ntchito ndi makulidwe a filimu a 17 mpaka 35μm.
3.Kupaka pamanja
Kupaka kwamtunduwu ndi mtundu wosavuta kwambiri wa kukulunga filimu, filimu yomwe imayikidwa pa alumali kapena pamanja, pozungulira pallet kapena filimu yozungulira pallet. Amagwiritsidwa ntchito pomanganso mapaleti atakulungidwa pambuyo pa kusweka, komanso ma CD wamba. Kupaka kwamtunduwu ndikochedwa ndipo makulidwe oyenera a kanema ndi 15 mpaka 20 μm.
