Kurambura firime mubisanzwe bikoreshwa muma firime menshi ya polyethylene ya elastike, bikozwe mugukoresha tekinoroji yo gukuramo firime yitwa "CAST".Firime isobanura ko urwego ruto rwibikoresho rufite ibintu bihamye kandi byoroshye.
Filime irambuye ni firime ya plastike irambuye cyane ikozwe mu bikoresho bishingiye kuri polyethylene (PE) kandi ikoreshwa cyane mu gupfunyika pallet kugirango ibashe gupakira neza uburyo bwo gutwara no kubika neza.
Umurongo muto-wuzuye polyethylene (LLDPE) nibikoresho fatizo kugirango utange firime.Filime zacu zifite ubuziranenge cyane kubera imirongo igezweho igezweho hamwe nikoranabuhanga rigezweho, ndetse no gukoresha ibikoresho fatizo bitangwa nababikora bazwi.Umubare munini wa firime ya polyethylene utegurwa kuva mubucucike buke bwa Polyethylene metallocene) m- LLDPE), Umurongo muto wa polyethylene (LLDPE) na ultra-low-density polyethylene (ULDPE) irimo 0 na 8% polyisobutylene (PIB).
Gusaba
Gufunga gupfunyika / firime ikoreshwa muburyo bwo gupfunyika no kurinda imizigo ipakiye kuri pallets kubintu byihariye bifite ubunini bunini muri rusange, gukoresha firime irambuye nuburyo bwiza cyane bwo gupakira no gupfunyika ibicuruzwa bitewe nubunini bwacyo buke kandi birebire byemeza umutwaro uhagaze .
Kurambura firime / gupfunyika Imbaraga nimbaraga
Ubunini bwa firime yakozwe bwakozwe kuva kuri micrometero 10 kugeza kuri 35 zo gupfunyika no kurinda ibicuruzwa ukoresheje imashini zipakira.Ubugari bwa firime isanzwe: mm 500, birashoboka gukora indi firime yubugari mugwiza mm 250.
Filime irambuye ni iki?
Filime irambuye ni firime yoroheje, yagutse (mubisanzwe ikozwe muri polyethylene) ikoreshwa mugufunga no guhambira ibintu birinda pallets.Mugihe firime irambuye izengurutse pallet, impagarara zirakorwa kandi bigatuma firime yongera uburebure bwikubye inshuro 300.Iyi mpagarara noneho itera imbaraga ziterana hafi yumutwaro kandi igahora mumwanya wabyo.
Ubwoko bwa firime zirambuye
Hariho ubwoko bubiri bwingenzi bwa firime: kurambura intoki na firime yo kurambura imashini.
1. Filime yo kurambura intoki
Filime yo kurambura intoki yateguwe muburyo bwihariye bwo gukoresha intoki bityo rero ikoreshwa mubunini buke mubikorwa byo gupakira no gupfunyika.Byasuzumwe kubipfunyika intoki.Umubyimba wa firime yakozwe ni kuva kuri micrometero 10 kugeza kuri 40 naho ubugari ni mm 450 cyangwa mm 500, tensile 100% byemejwe.Filime yakorewe ku mashini zikoresha zifite ibikoresho bigenzura uburebure n'uburemere bwa firime kuri muzingo.
2. Imashini irambura imashini
Imashini irambura imashini ni firime yagenewe gukoreshwa muburyo bwo gukurura imashini zikurura kandi ubusanzwe ikoreshwa mubikorwa binini byo gupakira no gupfunyika.Ubwoko bumwe busanzwe bwimashini za firime zirambuye zirimo:
- Blown Stretch Film- Yakozwe hakoreshejwe uburyo bwo gukuramo ibicuruzwa.Iyi nzira ikubiyemo guhuha ibisigazwa bishyushye mubibyimba.Igituba noneho gihinduka impapuro zizunguruka zigashyirwa kumurongo wibanze.
Kora Stretch Film - Yakozwe hakoreshejwe inzira yo gukuramo.Ubu buryo bukubiyemo kugaburira ibisusu bishyushye binyuze kumurongo wikonje ikonje, hanyuma igashimangira firime.
Filime Yabanjirije- Ni firime yamaze kwagurwa mubyiciro byo gukora.
