Firime yo gupakira plastiqueni kimwe mubikoresho byingenzi byo gupakira. Hariho ubwoko bwinshi bwo gupakurura plastiki hamwe nibiranga bitandukanye, kandi uburyo bwabo buratandukanye ukurikije ibintu bitandukanye bya firime yapakira.
Filime yo gupakira ifite uburemere, kurwanya ubuhehere, hamwe n'imikorere ishyushye, kandi ikoreshwa cyane: Filime yo gupakira PVDC irakwiriye gupakira kandi irashobora gukomeza gushya igihe kirekire; Na firime yo gupakira amazi ya Pva irashobora gukoreshwa utakinguye kandi ushyizwe mumazi; Filime ya PC ifite impumuro nziza, idafite uburozi, hamwe na transparency hamwe na transparency hamwe nintoki nkimpapuro, kandi irashobora guhumeka no gusiganwa ku bushyuhe bwo hejuru nigitutu.
Mu myaka yashize, ibyifuzo byisi byo gupakira plastiki byagaragaje uburyo buhoraho, cyane cyane uko gupakira bikomeje kuva mumipaki ikomeye kubipfunyika byoroshye. Nibintu bikomeye bitwara imikurire mugusaba ibikoresho bya firime. None, uzi ubwoko no gukoresha firime yo gupakira plastiki? Iyi ngingo izamenyekanisha ahanini imitungo no gukoresha firime nyinshi zo gupakurura plastike
1. Filime zo gupakira Polyethylene
PE FACAPING YAKARA NUBUNTU BUKORESHEJWE CYANE, KUBARA KUBIKORWA BIKURIKIRA 40% Nubwo pelm yo gupakira atari nziza mubijyanye no kugaragara, imbaraga, nibindi, igira uburemere, nubushyuhe bwo gushyuha, kandi biroroshye gutunganya no gukora cyane, bityo birakoreshwa cyane.
a. Ubucucike bwa Polyethylene.
Filime yo gupakira iseswa ikozwe ahanini nuburebure bukurura uburyo bubi kandi t-Mold. Ni firime yo gupakira kandi ikwiye gupakira idafite uburozi kandi ifite impumuro, hamwe nubunini muri rusange hagati ya 0.02-0.1mm. Ifite amazi meza, kurwanya ubuhehere, imitako y'amapfa, no gushikama imiti. Umubare munini wibishushanyo mbonera byibihe byapakira ibiryo byakonje bikoreshwa kubiryo, ubuvuzi, ibikenewe bya buri munsi, nibicuruzwa byicyuma. Ariko kubintu hamwe nubushuhe buke hamwe nibisabwa byo kurwanya ubushuhe byinshi, filime yo gupakira ubuhehere hamwe na firime zipakishwa zifatika zigomba gukoreshwa mugupakira. Filime yo gupakira ishyacyaha ifite urunuka rwinshi, nta mpumuro nziza, n'amavuta yo kurwanya peteroli, bigatuma bidakwiriye gupakira byoroshye, ibiryo biryoshye, n'ibiyaga biryoshye, n'ibiyaga biryoshye. Ariko kwaguka kwayo bituma bikwirakwira - gupakira ibintu bishya nkibintu byiza nimboga. Filime yo gupakira illdion ifite ubushyuhe bwinshi kandi bufite ubushyuhe bukabije bwa kashe, bityo birakoreshwa nkigice gifatika hamwe nubushyuhe bwa salle yo gupakira firime. Ariko, kubera kurwanya ubushyuhe buke, ntishobora gukoreshwa nkubushyuhe bwa kashe yo guteka imifuka.
b. Ubucucike bwimbitse bwa Polyethylene film. Filime ya HDpe ni filme ifunga filme ipakira hamwe nata amata yera nubutaka bubi. Filime yo gupakira hdpe ifite imbaraga zidake cyane, kurwanya ubuhehere, kurwanya ubushyuhe, kurwanya peteroli, no gutuza kwa peteroli, no gutuza kwamavuta, no gutuza kwamavuta, no gutuza kwa peteroli, no gutuza kwa peteroli, no gutuza kwamavuta kuruta firime yo gupakira LDPE. Irashobora kandi kuba ubushyuhe, ariko gukorera mu mucyo ntabwo ari byiza nka ldpe. Hdpe irashobora gukorwa muri firime yo gupakirana hamwe nubwinshi bwa 0.01mm. Isura yacyo isa cyane nimpapuro za silk yubudodo, kandi byumva neza gukoraho, bizwi kandi nkimpapuro nka firime. Ifite imbaraga, gukomera, no gufungura. Kugirango wongere impapuro nkumva kandi ugabanye ibiciro, umubare muto wa carboum yoroheje ya calcium yoroheje irashobora kongerwaho. Umukino w'impapuro za HDPE ukoreshwa cyane cyane mu gukora imifuka itandukanye yo guhaha, imifuka yimyanda, imifuka yimbuto, hamwe nimifuka itandukanye y'ibiryo. Kubera ibyago byayo byo kurenga no kubura impumuro nziza, igihe cyo kubika ibiryo gipfunyitse ntabwo ari kirekire. Mubyongeyeho, firime yo gupakira HDPA irashobora gukoreshwa nkikibanza cya kashe yo guteka imifuka kubera kurwanya ubushyuhe bwiza.
c. Umurongo-wubusa-ubucucike bwa polyethylene firime yo gupakira.
Filime yo gupakira LLDPe ni ubwoko butandukanye bwateye imbere bwa firime yo gupakira Polyethylene. Ugereranije na firime ya ldpe, film yo gupakira LLDP ifite imbaraga nyinshi ningaruka, imbaraga zo gutaka, no kurwanya uturere. Hamwe nimbaraga zimwe nigikorwa cya firime ya LDPE, umubyimba wa filtpe ya lilpe urashobora kugabanywa kuri firime ya 2-25% ya firime ya ldpe, bityo bikagabanya ibiciro. Ndetse iyo bikoreshejwe nkumufuka uremerera upakira, ukeneye gusa kuba 0.1m kugirango wuzuze ibisabwa, bishobora gusimbuza polymer ihenze-ubucucike bwa polyethlene. Kubwibyo, LLDPE irakwiriye cyane gupakira buri munsi gupakira, gupakira ibiryo byakonje, kandi bikoreshwa cyane nkumufuka mwinshi hamwe nimifuka yimyanda.
2. Film Polypropylene Film yo gupakira
Filime yo gupakira PP igabanijwemo firime ipakira hamwe na firime yo gupakira. Ubwoko bubiri bwa firime yo gupakira bafite itandukaniro ryingenzi mubikorwa, bityo bigomba gufatwa nkubwoko bubiri butandukanye bwa firime yo gupakira.
1) Film ya Polyplepylene.
Filime idakira ya Polypropylene ikubiyemo firime yo gupakira Polypropylene (IPP) Yakozwe nuburyo bwo gukurura ibicuruzwa byapakira polypropylene (CPP) byakozwe nuburyo bwa T-Mold. Gukorera mu mucyo no gukomera kwa firime yo gupakira PP birakennye; Kandi ifite gukorera mu mucyo hejuru no gukomera. Filime ya CPP ifite gukorera mu mucyo kandi nziza, kandi isura yayo isa niyi mpapuro. Ugereranije na pef film yapakiye, film yo gupakira Polyplepylene ifite gukorera mu mucyo, uburozi, kurwanya ubuhehere, kurwanya ubushyuhe, n'amavuta yo kurwanya amavuta Imbaraga nyinshi zamashanyarazi, irwanya amarira, yo kurwanya uturere, kandi wambara kurwanya; Kandi ntabwo ari uburozi kandi butagira impushya. Kubwibyo, bikoreshwa cyane mugupakira ibiryo, imiti, imyenda nibindi bintu. Ariko yatewe amapfa make yo kurwanya kandi akaboroka kuri 0-10 ℃, ntibishobora gukoreshwa kugirango apakira ibiryo byakomeretse. Filime idahwitse Polypropylene ifite ubushyuhe bwinshi nubushyuhe bwiza bwo gufunga, bityo birakoreshwa nkibinini bya kashe yo guteka imifuka yo guteka.
2) Biaxited igana kuri firime yo gupakira polypropylene (bopp).
Ugereranije na firime yo gupakira polypropylene, film yo gupakira ya bopfes ahanini ifite ibiranga bikurikira: ① Kunoza gukorera mu mucyo no kuba indabyo, ugereranije impapuro z'ikirahure; Decle Imbaraga zubureya ziriyongera, ariko kurahira bigabanuka; Gutezimbere kurwanya ubukonje kandi nta bwenge nubwo wakoreshwaga kuri -30 ~ -50 ℃; Ubushuhe bushingiye ku bushuhe no mu kirere bugabanuka hafi kimwe cya kabiri, kandi imyuka kama rusange iragabanuka kuri dogere zitandukanye; Filime imwe ntishobora kuba ifunze itaziguye, ariko imikorere yubushyuhe irashobora kunozwa no guhimba ingirakamaro hamwe nibindi bikoresho byo gupakira plastike.
Filime ya Bopp ni ubwoko bushya bwa firime yo gupakira kugirango isimbure impapuro. Ifite ibiranga imbaraga zubukanishi, gukomera, gukorera mu mucyo bwiza no guhora. Igiciro cyacyo kiri munsi ya 20% kurenza iyi mpapuro. Yasimbuye rero cyangwa igice cyasimbuwe impapuro z'ikirahure mu gupakira ibiryo, ubuvuzi, itabi, imyenda, n'ibindi bicuruzwa. Ariko imbaraga zayo ziri hejuru kandi ntishobora gukoreshwa mu gupakira ya bombo. Filime ya Bopp ikoreshwa cyane nkibikoresho fatizo byo gupakira firime. Filime zipakira ikozwe muri foil foil hamwe nibindi bipakurura bya prostike bya plastike birashobora kuzuza ibisabwa bipakira ibintu bitandukanye kandi byakoreshejwe cyane.
3. Filviny ya chloride ya chloride
Filime ya PVC igabanijwemo film yo gupakira hamwe na firime yo gupakira. Kurambura, kurwanya amarira, no kurwanya ubukonje bwa firime yo gupakira PVC nibyiza; Byoroshye gucapa no gushuka kashe; Irashobora gukorwa muri firime yo gupakira. Kubera impumuro ya plastiziya no kwimuka kwa plastistizers, firime yo gupakira pvc muri rusange ntabwo ikwiriye gupakira ibiryo. Ariko film yo gupakira pvc yakozwe nuburyo bwa plastiki yimbere irashobora gukoreshwa mugupakira ibiryo. Muri rusange, PVC ya pasika ipakishwa cyane ikoreshwa cyane kubicuruzwa byinganda nibipfunyika ibiryo.
Filime ya PVC ikomeye PVC, mubisanzwe bizwi ku izina rya PVC. Gukorera mu mucyo Mugari, gukomera, gukomera, kandi bigoramye; Ifite umwuka mwiza, kugumana impumuro, nubushuhe bwiza; Imikorere myiza yo gucapa, irashobora kubyara film yo gupakara. Irakoreshwa cyane cyane guhindagurika kwa bombo, gupakira imyenda n'imyambaro, kimwe na firime yo gupakira hanze yitabi hamwe no gupakira ibiryo. Ariko, PVC ikomeye ifite ubukonje bukabije kandi ihinduka ubushyuhe buke, bigatuma bidakwiriye nkibikoresho bipakira kubiryo byakonje.
