Ni ubuhe buryo bwo gutangiza plastikifilms?

Filime ya plastike yerekana icyiciro cyibanze cyibikoresho bya polymeriki birangwa nuburyo bworoshye, bworoshye kandi bugari. Ibi bikoresho bya injeniyeri bikozwe mugutunganya polymer-yaba ikomoka kuri peteroli cyangwa igenda ikomoka kumasoko ashobora kuvugururwa-mumpapuro zikomeza zifite ubugari, ubugari, hamwe nubukanishi. Isoko rya firime ya pulasitike ku isi ryazamutse cyane kuva ryatangira hagati mu kinyejana cya 20, aho umusaruro uva buri mwaka urenga toni miliyoni 100 ku isi.

Ubwinshi bwa firime ya plastike ituruka kubintu byihariye bidasanzwe bihuza imitungo: yoroheje nyamara iramba, ihindagurika ariko ikomeye, kandi ibonerana cyangwa idasobanutse bitewe nibisabwa. Ibi biranga, hamwe nigiciro gito cyo gukora, byatumye firime ya plastike ari ntangarugero mubice byose byinganda zigezweho nubuzima bwa buri munsi. Kuva kubungabunga ibiryo bishya kugeza kubikoresho bya elegitoroniki byoroshye, firime ya pulasitike ikora imirimo akenshi itagaragara kubakoresha amaherezo ariko ikagira akamaro kubikorwa no kuramba.

Iterambere rya vuba mubumenyi bwibintu ryaguye ubushobozi bwa firime ya plastike irenze kure inshingano zabo gakondo. Udushya turimo firime zihindura imitungo mugusubiza ibidukikije, ibinyabuzima bishobora kwangirika kuri plastiki zisanzwe, hamwe na firime ya barrière ikora cyane ifite ubushobozi bwo kurinda bitigeze bibaho. Icyarimwe, ibibazo by’ibidukikije bigenda byiyongera byatumye habaho iterambere rya sisitemu yo gutunganya ibicuruzwa bifunguye hamwe n’ibikoresho bya firime bishingiye kuri bio bikomeza imikorere mu gihe bigabanya ingaruka z’ibidukikije.

Ni ubuhe bwoko bwa firime ya plastike?

Filime Yagutse

Filime polyethylene nubwoko bukoreshwa cyane muri firime ya plastike, bingana na 40% byamafirime yose ya plastike. Ubwoko Bwingenzi nibiranga Filime ya Polyethylene:

1. Filime nkeya ya Polyethylene (LDPE)

Filime ya LDPE irangwa nubworoherane, gukorera mu mucyo, hamwe nuburozi butagira uburozi, butagira impumuro nziza. Bafite amazi meza cyane, birwanya ubushuhe, hamwe n’imiti ihamye, bigatuma bikenerwa mu gupakira ibiryo, imiti, n’ibicuruzwa bikoreshwa buri munsi. Filime ya LDPE nayo ifite ibyiza byo gufunga ubushyuhe kandi akenshi ikoreshwa nkubushyuhe bwa kashe muri firime. Nyamara, zifite ubushyuhe buke kandi ntibukwiriye gupakira ubushyuhe bwo hejuru.

2. Filime yuzuye ya Polyethylene (HDPE)

Filime ya HDPE irakomeye, igice cyoroshye, kandi cyera mubara. Bagaragaza imbaraga zidasanzwe, kurwanya ubushuhe, kurwanya ubushyuhe, hamwe no kurwanya amavuta ugereranije na LDPE. HDPE ikwiranye no gupakira igihe kirekire hamwe na firime yinganda ariko ifite umucyo muke hamwe nuburabyo.

3. Filime Yumurongo Mucyo Mucyo Polyethylene (LLDPE)

Filime za LLDPE zihuza guhinduka kwa LDPE n'imbaraga za HDPE, zitanga uburyo bwiza bwo kurambura no kurwanya puncture. Zikoreshwa cyane muri firime zirambuye, kugabanya firime, no gufunga firime, bigatuma biba byiza muburyo bwihuse bwo gupakira.

4. Metallocene Linear Line-Ubucucike bwa Polyethylene (mLLDPE)

firime ya mLLDPE ikorwa hifashishijwe catalizike ya metallocene kandi itanga imbaraga zingaruka, imbaraga zitanga umusaruro, hamwe no gukorera mu mucyo ugereranije na LLDPE isanzwe. Bemerera kugabanya umubyimba wa firime hejuru ya 15%, bityo bikagabanya ibiciro byibikoresho. mLLDPE isanzwe ikoreshwa muri firime ya parike, firime zipakira ibintu biremereye, kugabanya firime, nibikoresho byo murwego rwohejuru.

Izindi Filime za Plastike

1. Filime ya PP itanga imiti irwanya imiti kandi ikoreshwa kenshi mubipfunyika ibiryo hamwe nibikoresho byo kwa muganga.

2. Filime ya Polyvinyl Chloride (PVC): Yahawe agaciro kubwumvikane budasanzwe no gucapwa ariko ihura nigabanuka kubera ikibazo cyibidukikije. Porogaramu zisigaye zirimo gupakira blister hamwe na firime zimwe zifata5.

3. Biaxically-yerekanwe PET (BOPET) yerekana cyane cyane imiterere ya mashini na barrière.

Filime yihariye ya Polymer:

1. Polyamide (Nylon): Indwara ya ogisijeni idasanzwe yo kubika ibiryo

2. Chloride ya Polyvinylidene (PVDC): Ubushuhe buhebuje hamwe na ogisijeni ikora neza

3.

Uburyo bwo Gutunganya Amashusho ya Plastike

1. Blown Film Extrusion: Igikorwa cyiganje muri firime za PE, aho polymer yashongeshejwe ikoherezwa mu rupfu ruzunguruka, igashyirwa mu bubyimba, hanyuma igakonjeshwa kugirango ikore umuyoboro ushobora guhindurwamo firime ebyiri. Ubu buryo butanga imiterere iringaniye mumashini yombi no guhinduranya.

2. Bisanzwe kuri firime ya PP na PET aho ibintu bya optique ari ngombwa.

3. Calendering: Byakoreshejwe cyane cyane muri firime ya PVC, aho uruganda rwa polymer runyuzwa murukurikirane rwimashini zishyushye kugirango ugenzure neza neza. Amafirime ya kalendari mubisanzwe afite ubuso bwo hejuru ariko butarimo imiterere yubukanishi buke mubugari.

4. Polimeri yashongeshejwe mumashanyarazi, ikajugunywa kumukandara, hanyuma ikuma kugirango ikore firime-isanzwe kuri firime zimwe na zimwe zishobora kwangirika hamwe nibisabwa.

5. Biaxically-PP (BOPP) na PET (BOPET) ni amahame yinganda zo gupakira neza.

Kugaragara no guhanga udushya muri firime ya plastiki

Inganda za firime za plastike ziratera imbere, hibandwa cyane ku kuramba, gukora, no gukora neza. Bimwe mubyerekezo bigaragara harimo:

1.PFAS Yubusa Yibikoresho:Ibikoresho biramba birinda ibintu- na polyfluoroalkyl (PFAS), bikemura ibibazo bikenewe hamwe nibidukikije.

. FDA yo muri Amerika yabonye ubwitange ku bushake bwo kuvana PFAS mu bipfunyika ibiryo, bigira uruhare mu kugabanya cyane imirire ya PFAS.

Ibisubizo bishya bya PFAS-yubusa itunganya ifasha firime ya plastike kuva SILIKE

SILIKE ifata inzira igaragara hamwe nibicuruzwa byayo bya SILIMER, itanga udushyaImfashanyigisho ya PFAS idafite ibikoresho (PPAs)). Uyu murongo wibicuruzwa byuzuye urimo 100% bya PFAS yubusa PPAs, ibicuruzwa bya PPA bidafite fluor, hamwe na PFAS idafite, fluor idafite PPA. Mugukuraho ibikenerwa byongerwaho fluor, ibyo bicuruzwa byongera cyane mubikorwa byo gukora LLDPE, LDPE, HDPE, mLLDPE, PP, nibicuruzwa bya firime. Bahuza n’amabwiriza agezweho y’ibidukikije ari nako azamura umusaruro, kugabanya igihe, no kuzamura ubwiza bwibicuruzwa muri rusange. Hamwe na SILIKE PFAS idafite PPA izana inyungu zanyuma zicuruzwa, harimo: kurandura kuvunika gushonga (uruhu rwa shark), kongera ubworoherane, hamwe nubuziranenge bwubuso.
