Filime zitandukanye zikoreshwa kenshi mubuzima bwa buri munsi. Ni ibihe bikoresho aya mafilime akozwe? Ni ibihe bintu biranga imikorere ya buri? Ibikurikira nintangiriro irambuye kuri firime ya plastike ikoreshwa mubuzima bwa buri munsi:
Filime ya plastike ni firime ikozwe muri chloride ya polyvinyl, polyethylene, polypropilene, polystirene nandi mabati, akenshi ikoreshwa mubipfunyika, mu bwubatsi, ndetse no murwego rwo gutwikira, nibindi.
Filime ya plastike irashobora kugabanywamo
–Firime yinganda: firime yatunganijwe, firime ya kalendari, firime irambuye, film yabakinnyi, nibindi.;
- Filime yamashanyarazi yubuhinzi, firime ya mulch, nibindi.;
–Filime zo gupakira (harimo firime yibikoresho byo gupakira imiti, firime yibikoresho byo gupakira ibiryo, nibindi).
Ibyiza n'ibibi bya firime ya plastiki :
Ibiranga firime nyamukuru ya plastiki :
Filime ya Polypropilene yerekanwe (BOPP)
Polypropilene ni resimoplastique resin ikorwa na polymerisation ya propylene. Ibikoresho bya Copolymer PP bifite ubushyuhe buke bwo kugoreka ubushyuhe (100 ° C), gukorera mu mucyo muke, ububengerane buke, no gukomera, ariko bifite imbaraga zikomeye, kandi imbaraga za PP ziyongera hamwe no kwiyongera kwa Ethylene. Ubushyuhe bwa Vicat bwa PP ni 150 ° C. Bitewe nurwego rwo hejuru rwa kristu, ibi bikoresho bifite isura nziza cyane yo gukomera hamwe nuburyo bwo guhangana. PP ntabwo ifite ibibazo byo guhagarika ibidukikije.
Filime ya polypropilene yerekanwe (BOPP) ni ibikoresho byoroshye byo gupakira byakozwe mu myaka ya za 1960. Ikoresha umurongo udasanzwe wo gukora kugirango uvange ibikoresho fatizo bya polipropilene ninyongeramusaruro ikora, ushonga hanyuma ubikate mumpapuro, hanyuma ubirambure muri firime. Ikoreshwa cyane mu gupakira ibiryo, bombo, itabi, icyayi, umutobe, amata, imyenda, n'ibindi, kandi ifite izina rya “Packaging Queen”. Mubyongeyeho, irashobora kandi gukoreshwa mugutegura ibicuruzwa byongerewe agaciro cyane nkibikorwa byamashanyarazi nka microporous membrane, bityo ibyerekezo byiterambere bya firime BOPP ni binini cyane.
Filime ya BOPP ntabwo ifite ibyiza gusa byubucucike buke, kurwanya ruswa neza no kurwanya ubushyuhe bwiza bwa PP resin, ariko kandi ifite imiterere myiza ya optique, imbaraga za mashini nyinshi nisoko ryinshi ryibikoresho fatizo. Filime ya BOPP irashobora guhuzwa nibindi bikoresho bifite imitungo yihariye kugirango irusheho kunoza cyangwa kunoza imikorere. Ibikoresho bisanzwe bikoreshwa harimo firime ya PE, salivating polypropylene (CPP), polyvinylidene chloride (PVDC), firime ya aluminium, nibindi.
Ubucucike Buke bwa Polyethylene (LDPE)
Filime ya polyethylene, ari yo PE, ifite ibiranga kwihanganira ubushuhe hamwe n’ubushyuhe buke.
Polyethylene nkeya (LPDE) ni resinike yubukorikori yabonetse na Ethylene radical polymerisation kumuvuduko mwinshi, bityo nanone yitwa "polyethylene yumuvuduko ukabije". LPDE ni molekile ishami ifite amashami yuburebure butandukanye kumurongo wingenzi, hamwe na Ethyl igera kuri 15 kugeza 30, butyl cyangwa amashami maremare kuri atome ya karubone 1000 mumurongo nyamukuru. Kuberako urunigi rwa molekile rurimo urunigi rurerure kandi rugufi rufite amashami, ibicuruzwa bifite ubucucike buke, ubworoherane, ubushyuhe buke, kurwanya ingaruka nziza, imiti ihamye, hamwe no kurwanya aside (usibye aside irike ikomeye), Alkali, ruswa yumunyu, ifite ibyiza ibikoresho byo gukwirakwiza amashanyarazi. Ihinduranya kandi irabagirana, ifite imiti ihamye yimiti, ubushyuhe bwo gufunga ubushyuhe, kurwanya amazi nubushyuhe, kurwanya ubukonje, kandi birashobora gutekwa. Ingaruka nyamukuru yacyo ni inzitizi mbi ya ogisijeni.
Bikunze gukoreshwa nka firime yimbere yimbere yibikoresho byo gupakira byoroshye, kandi ni na firime ikoreshwa cyane kandi ikoreshwa cyane muri iki gihe, ikaba irenga 40% yo gukoresha firime zipakira plastike. Hariho ubwoko bwinshi bwa firime ya polyethylene, kandi imikorere yabo iratandukanye. Imikorere ya firime imwe-imwe ni imwe, kandi imikorere ya firime ikomatanya iruzuzanya. Nibikoresho byingenzi byo gupakira ibiryo. Icya kabiri, firime polyethylene nayo ikoreshwa mubijyanye nubwubatsi bwa gisivili, nka geomembrane. Ikora nk'amazi adafite amazi muri injeniyeri yububatsi kandi ifite ubushobozi buke cyane. Filime yubuhinzi ikoreshwa mubuhinzi, ishobora kugabanywamo firime yamenetse, firime ya mulch, firime itwikiriye, firime yo kubika icyatsi nibindi.
Filime ya polyester (PET)
Filime ya polyester (PET), ikunze kwitwa polyethylene terephthalate, ni plastiki yubuhanga bwa termoplastique. Nibikoresho bya firime bikozwe mumpapuro zibyibushye mugusohora hanyuma bikaramburwa. Filime ya polyester irangwa nubukorikori buhebuje, gukomera cyane, gukomera no gukomera, kurwanya gucumita, kurwanya ubukana, ubushyuhe bwinshi no kurwanya ubushyuhe buke, kurwanya imiti, kurwanya amavuta, gukomera kwumwuka no kugumana impumuro nziza. Imwe muma firime ahoraho igizwe, ariko kurwanya corona ntabwo ari byiza.
Igiciro cya firime ya polyester ni kinini, kandi ubunini bwayo ni mm 0,12. Bikunze gukoreshwa nkibikoresho byo hanze bipfunyika ibiryo, kandi bifite icapiro ryiza. Byongeye kandi, firime ya polyester ikoreshwa kenshi nko gucapa no gupakira ibintu bikoreshwa nka firime yo kurengera ibidukikije, firime ya PET, na firime yera y’amata, kandi ikoreshwa cyane mu nganda nka fibre fibre ikomeza plastike, ibikoresho byubaka, icapiro, n’ubuvuzi n’ubuzima.
Filime ya Nylon (ONY)
Izina ryimiti ya nylon ni polyamide (PA). Kugeza ubu, hari ubwoko bwinshi bwa nylon bwakozwe mu nganda, kandi ubwoko bwingenzi bukoreshwa mu gukora firime ni nylon 6, nylon 12, nylon 66, nibindi. imbaraga zingana, hamwe no kurwanya ubushyuhe bwiza, kurwanya ubukonje, kurwanya amavuta hamwe no kurwanya ibishishwa. Kwambara neza cyane no kwihanganira gutobora, ugereranije byoroshye, ibyiza bya ogisijeni nziza, ariko imiterere mibi ya barrière kumazi wumuyaga, kwinjiza amazi menshi hamwe nubushuhe bwamazi, kutagira ubushyuhe buke, bikwiranye no gupakira ibintu bikomeye, nkibiryo byamavuta yimibonano mpuzabitsina, ibikomoka ku nyama, bikaranze ibiryo, ibiryo byuzuye vacuum, ibiryo bihumeka, nibindi.
Fata Filime ya Polypropilene (CPP)
Bitandukanye na firime ya polypropilene yerekanwe (BOPP), firime ya polypropilene (CPP) ni firime idasakaye, idafite icyerekezo cya firime ikozwe na firime yo gushonga no kuzimya. Irangwa n'umuvuduko wihuse, ibisohoka cyane, firime nziza mucyo, gloss, uburinganire buringaniye, hamwe nuburinganire bwiza bwimiterere itandukanye. Kuberako ari firime ikozwe neza, gukurikirana imirimo nko gucapa no guteranya biroroshye cyane. CPP ikoreshwa cyane mugupakira imyenda, indabyo, ibiryo, nibikenerwa bya buri munsi.
Amashanyarazi ya aluminiyumu
Filime ya aluminiyumu ifite ibiranga firime ya plastike n'ibiranga icyuma. Uruhare rwa plaque ya aluminiyumu hejuru ya firime ni ukurinda urumuri no kwirinda imirasire ya ultraviolet, ntabwo yongerera igihe cyo kuramba gusa ibirimo, ahubwo inazamura umucyo wa firime. Kubwibyo, firime ya aluminiyumu ikoreshwa cyane mubipfunyika byinshi, bikoreshwa cyane mubipfunyika byumye kandi bisukuye nka biscuits, ndetse no gupakira hanze imiti imwe n'imwe yo kwisiga.
