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 zotsatira zodzimatira za filimu yotambasula ya PVC. Chifukwa cha mavuto azachilengedwe, mtengo wokwera (poyerekeza ndi PE, malo ochepa opakira pa unit) komanso kusatambasuka bwino, filimu yotambasula ya PE idachotsedwa ntchito pamene kupanga kwapakhomo kunayamba mu 1994-1995. Zinthu zoyambira makamaka ndi LLDPE, kuphatikiza C4, C6, C8 ndi metallocene PE (MPE).
Zinthu Zofunika
Imapangidwa pogwiritsa ntchito LLDPE resin ndi tackifier special additives zomwe zimalowetsedwa kunja, ndipo imatha kupanga multifunctional winding film yamanja, resistance type machine, pre-stretch type machine, anti-UV, anti-static ndi anti-dzimbiri. Ili ndi ubwino wotsatira:
1. Pogwiritsa ntchito zida ziwiri zotulutsira pamodzi, filimu yozungulira yosindikizidwa imatha kukulitsa mawonekedwe a polima iliyonse, kuwonekera kwake, mphamvu yake yokoka, ndi kukana kubowoka, kufikira pamalo abwino kwambiri pamalo osungunuka.
2. Ili ndi mphamvu zabwino zokoka, mawonekedwe abwino, komanso makulidwe ofanana.
3. Ili ndi kutalika kwa nthawi yayitali, kulimba bwino, kukana kung'ambika kopingasa, komanso kulimba bwino kwambiri.
4. Ndi zinthu zobwezerezedwanso zachilengedwe, zopanda kukoma, zopanda poizoni, ndipo zimatha kupakidwa chakudya mwachindunji.
5. akhoza kupanga zinthu zomatira za mbali imodzi, kuchepetsa phokoso lotuluka panthawi yokhotakhota ndi kutambasula, kuchepetsa fumbi ndi mchenga panthawi yonyamula ndi kusunga.
Kugwiritsa ntchito
1. Ma phukusi otsekedwa
Mtundu uwu wa kulongedza uli ngati kulongedza kwa filimu yochepa, komwe filimuyo imakulungidwa mozungulira pallet kuti iphimbidwe yonse, kenako zolumikizira ziwiri zotenthetsera zimatenthetsa filimuyo mbali zonse ziwiri pamodzi. Iyi ndi njira yoyamba yogwiritsira ntchito kulongedza filimu ndipo yapangitsa kuti pakhale mitundu yambiri yolongedza.
2. Ma CD onse m'lifupi
Mtundu uwu wa phukusi umafuna kuti filimuyo ikhale yayikulu mokwanira kuti iphimbe phale, lomwe lili ndi mawonekedwe ofanana, kotero ndi loyenera kugwiritsidwa ntchito ndi makulidwe a filimu ya 17 mpaka 35μm.
3. Kupaka ndi manja
Mtundu uwu wa phukusi ndi mtundu wosavuta kwambiri wa phukusi la filimu yokulunga, filimu yoyikidwa pa shelufu kapena yogwiritsidwa ntchito ndi manja, pogwiritsa ntchito phukusi lozungulira kapena filimu yozungulira phukusi. Amagwiritsidwa ntchito makamaka pokonza mapaleti okulungidwa akasweka, komanso phukusi wamba. Mtundu uwu wa phukusi ndi wocheperako ndipo makulidwe oyenera a filimu ndi 15 mpaka 20 μm.
