Ni iki gishyirwa mu bikorwa bya pulasitiki?films?

Filimi za pulasitiki zigaragaza ubwoko bw'ibanze bw'ibikoresho bya polymeri birangwa n'imiterere yabyo yoroshye kandi yoroshye hamwe n'ubuso bunini. Ibi bikoresho byakozwe mu buryo bwa tekiniki bikorwa binyuze mu gutunganya resine za polymeri—zaba zikomoka kuri peteroli cyangwa nyinshi mu masoko ashobora kongera gukoreshwa—bikaba impapuro zihoraho zifite ubugari, ubugari, n'imiterere ya mashini igenzurwa neza. Isoko ry'isi yose rya filime za pulasitiki ryariyongereye cyane kuva ryashingwa hagati mu kinyejana cya 20, aho umusaruro wa buri mwaka urenga toni miliyoni 100 ku isi yose.

Ubushobozi bwo gukora filime za pulasitiki buturuka ku miterere yazo yihariye: zoroshye ariko ziramba, zoroshye kandi zikomeye, kandi zibonerana cyangwa zidasobanutse bitewe n'ibisabwa mu gukora. Izi miterere, hamwe n'ikiguzi gito cyo gukora, byatumye filime za pulasitiki ziba ingenzi cyane muri buri rwego rw'inganda za none n'ubuzima bwa buri munsi. Kuva ku kubungabunga ibiryo bishya kugeza ku gukoresha ikoranabuhanga rigezweho ryoroshye, filime za pulasitiki zikora imirimo idasanzwe idakunze kubonwa n'abazikoresha ariko ikaba ingenzi ku mikorere myiza no kurambye kw'ibicuruzwa.

Iterambere riherutse mu bumenyi bw'ibintu ryazamuye ubushobozi bwa filime za pulasitiki burenga kure cyane inshingano zazo zisanzwe. Udushya turimo filime zihindura imiterere yazo bitewe n'ibintu bihungabanya ibidukikije, izindi filime zishobora kwangirika aho kuba pulasitiki isanzwe, na filime zirinda ibidukikije zifite ubushobozi bwo kurinda butigeze bubaho. Muri icyo gihe, impungenge zikomeje kwiyongera ku bidukikije zatumye habaho iterambere rya sisitemu zo kongera gukoresha ibikoresho bya filime zishingiye ku binyabuzima zikomeza gukora neza mu gihe zigabanya ingaruka ku bidukikije.

Ni ubuhe bwoko bwa filime ya pulasitiki?

Filime zikunze kugaragara cyane

Filimi za polyethylene ni zo zikoreshwa cyane muri filime za pulasitiki, zirenga 40% by'ikoreshwa rya filime zose za pulasitiki. Ubwoko bw'ingenzi n'ibiranga filime za polyethylene:

1. Filimi ya Polyethylene ifite ubucucike buke (LDPE)

Filimi za LDPE zirangwa no koroha kwazo, kugaragara neza, no kutangiza impumuro mbi. Zifite ubushobozi bwo kwirinda amazi, kwirinda ubushuhe, no kudahinduka mu binyabutabire, bigatuma zikoreshwa mu gupakira ibiryo, imiti, n'ibindi bicuruzwa bikoreshwa buri munsi. Filimi za LDPE zifite ubushobozi bwo kuziba ubushyuhe kandi zikunze gukoreshwa nk'ibice bifunga ubushyuhe muri filimi zivanze. Ariko, ntizishobora kuziba ubushyuhe bwinshi kandi ntizikwiriye gupakira mu bushyuhe bwinshi.

2. Filimi ya Polyethylene ifite ubucucike bwinshi (HDPE)

Filimi za HDPE zirakomeye, zifite ibara ry'umweru kandi zirakomeye. Zigaragaza imbaraga zo gukurura, zirwanya ubushuhe, zirwanya ubushyuhe, kandi zirwanya amavuta ugereranyije na LDPE. HDPE ikwiriye gukoreshwa mu gupfunyika no mu nganda ariko ifite ubwiza buke kandi irabagirana.

3. Filimi ya Polyethylene ifite ubucucike buke (LLDPE)

Filimi za LLDPE zihuza ubushobozi bwo koroha bwa LDPE n'imbaraga za HDPE, zitanga ubushobozi bwiza bwo kunanura no kudapfundika. Zikoreshwa cyane muri firime zo kunanura, firime zo gupfunyika, na firime zo gupfunyika, bigatuma ziba nziza cyane mu gupfunyika mu buryo bwihuta.

4. Filimi ya Polyethylene yo mu bwoko bwa Metallocene Linear Low-Density (mLLDPE)

Filimi za mLLDPE zikorwa hakoreshejwe metallocene catalysts kandi zitanga imbaraga nyinshi, imbaraga zo gukurura, no gukorera mu mucyo ugereranije na LLDPE isanzwe. Zituma ubugari bwa filime bugabanukaho hejuru ya 15%, bityo bikagabanya ikiguzi cy'ibikoresho. MLLDPE ikunze gukoreshwa muri filime zikoreshwa mu bushyuhe, filime zipfunyika cyane, filime zigabanya ubushyuhe, n'ibikoresho byo gupfunyika byo mu rwego rwo hejuru.

Izindi filime za pulasitiki

1. Filimi za Polypropylene (PP): Zizwiho gushonga cyane (160-170°C), bigatuma zikoreshwa mu gupfunyika no mu gupfunyika mu buryo butarimo ubushyuhe. Filimi za PP zirwanya imiti kandi zikunze gukoreshwa mu gupfunyika ibiryo by'akantu gato no mu gupfunyika ibikoresho by'ubuvuzi.

2. Filimi za Polyvinyl Chloride (PVC): Zifite agaciro ko kuba zisobanutse neza kandi zishobora gucapwa neza ariko zigakoreshwa nabi bitewe n’ibibazo by’ibidukikije. Izindi porogaramu zisigaye zirimo gupakira blister na filime zimwe na zimwe zo gufatisha.

3. Filimi za Polyester (PET): Zifite imbaraga nyinshi zo gukurura no kudahungabana k'ubushyuhe, filime za PET ni ingenzi cyane mu bikoresho by'ikoranabuhanga byoroshye, kaseti za rukuruzi, no gupakira ibiryo bifite imipaka myinshi. PET (BOPET) ifite imiterere myiza cyane ya mekanike n'imipaka.

Filimi zidasanzwe za polymer:

1. Polyamide (Nylon): Imiterere idasanzwe yo kubuza umwuka wa ogisijeni mu kubika ibiribwa

2. Polyvinylidene Chloride (PVDC): Ingufu zidasanzwe zo kubuza amazi n'umwuka wa ogisijeni

3. Aside Polylactic (PLA): Ubundi buryo bushya bushingiye ku binyabuzima bufite ubushobozi bwo gufumbira, nubwo busanzwe bugamirwa no kugorama—iterambere riherutse ryakozwe rya filime zoroshye za PLA binyuze mu gushyiramo pulasitiki ya polyether mu muyoboro wa polymer.

Uburyo bwo gukora filime ya pulasitiki

1. Gusohora firime ishyushye: Uburyo bwiganje muri firime za PE, aho polimeri ishongeshejwe inyuzwa mu cyuma kizenga, ikabyimba mu cyuma, hanyuma igakonjeshwa kugira ngo habeho umuyoboro ushobora guhindurwamo firime y’icyiciro kibiri. Ubu buryo butanga imiterere ingana ya mashini haba mu cyerekezo cy’imashini ndetse no mu cyerekezo cyayo.

2. Gusohora Filime: Polymer melt inyuzwa mu cyuma gikonjesha, igasohokana filime zifite ubuziranenge budasanzwe n'ubugari bungana. Zisanzwe muri filime za PP na PET aho imiterere y'urumuri ari ingenzi.

3. Gupima ubushyuhe: Bikoreshwa cyane cyane kuri firime za PVC, aho polimeri inyuzwa mu buryo butandukanye kugira ngo hagenzurwe neza ubunini. Filime za kera ziba zifite ubuso bwiza ariko zifite ubushobozi buke bwo gukorana mu bugari.

4. Gucana umuti: Bikoreshwa mu mafirime yihariye aho ubushyuhe cyangwa ubushobozi bwo gushonga butuma ibintu bishonga. Polima ishongeshwa mu buryo bwa solvent, igashyirwa ku mukandara, hanyuma ikayumishwa kugira ngo ikore firime—ikunze gukoreshwa muri amwe mu mafirime ashobora kubora no mu ruhu.

5. Icyerekezo cya Biaxial: Filimi zirambuwe haba mu cyerekezo cy’imashini ndetse no mu cyerekezo cyayo, haba mu buryo bukurikiranye (umugozi wo gufunga) cyangwa icyarimwe (uburyo bwo gufunga), binongera cyane imbaraga, ubwumvikane, n’imiterere y’inzitizi. Filimi za PP (BOPP) na PET (BOPET) zishingiye kuri Biaxial ni amahame ngenderwaho mu nganda kugira ngo zipake neza.

Imiterere n'udushya biri kugaragara muri filime za pulasitiki

Inganda za filime za pulasitiki zirimo gutera imbere, zibanda cyane ku kubungabunga ibidukikije, imikorere, n'imikorere myiza. Zimwe mu ntambwe zizwi zirimo:

1.Abakoresha Slipless Free PFAS:Ibintu biramba birinda ibintu bya per- na polyfluoroalkyl (PFAS), bikemura ibibazo by’imikorere ndetse n’ibijyanye n’ibidukikije.

2. Gahunda zo Kubungabunga Ubusugire bw'Ibiryo: Ibigo nka Fox Packaging byakuyeho PFAS mu buryo bwose bwo gupakira, bihuza n'amabwiriza yagutse n'inganda. Ikigo gishinzwe kurwanya ibiyobyabwenge cya Amerika (FDA) cyiyemeje gukuraho PFAS mu gupakira ibiryo, bigira uruhare mu kugabanya cyane imbogamizi ku mirire ya PFAS.

Ibisubizo bishya bya PFAS-Free filimi za pulasitiki zikoreshwa muri SILIKE

SILIKE ikoresha uburyo bwo gukora ibintu byayo bya serivise ya SILIMER, itanga udushyaUburyo bwo gutunganya polymer budafite PFAS (PPAS)). Uyu murongo wuzuye w'ibicuruzwa urimo 100% bya PPAS-free free PFAS, ibicuruzwa bya PPA bidafite fluorine, na PPA-free free fluorine-free PPAS. Mu gukuraho gukenera inyongeramusaruro za fluorine, ibi bicuruzwa byongera cyane inzira yo gukora LLDPE, LDPE, HDPE, mLLDPE, PP, na filime. Bijyanye n'amabwiriza agezweho yo kubungabunga ibidukikije mu gihe binatuma umusaruro urushaho kuba mwiza, bikagabanya igihe cyo kudakora, kandi bikanoza ubwiza bw'ibicuruzwa muri rusange. Hamwe na PPA idafite SILIKE PFAS bitanga inyungu za nyuma ku bicuruzwa, harimo: gukuraho uruhu rw'ishaka rushongeshejwe, koroshya uburyohe, no kugira ubwiza bw'ubuso.
