1, kumenyekanisha film ya polyester

Filime ya polyester nayo yitwa polyester film (PET) (firime yoroheje, film ya polyester, impapuro zoroshye, film ya polyester, firime ya benzene, selileophane, firime yo gusohora), ni terephthalate ya polyethylene nkibikoresho fatizo, gukoresha uburyo bwo gusohora muri firime yuzuye, hanyuma kurambura byerekezo byombi bikozwe mubikoresho bya firime.

Filime yo mu rugo (firime ya polyester, firime yo kurengera ibidukikije, firime ya PET, firime ya opal nibindi bikoresho byo gucapa no gupakira), ikoreshwa cyane mubirahuri bya fibre bishimangira inganda za plastiki, inganda zubaka, inganda zandika, ubuvuzi nubuzima.

Kugeza ubu, Ubushinwa bwateje imbere filime ya PET ihindagurika, ikaba idafite uburozi, idafite ibara, ibonerana, irwanya ubushuhe, ihumeka, yoroshye, ikomeye, amavuta-alkali amavuta kandi irwanya ibishishwa, kandi idatinya ubushyuhe bwo hejuru kandi buke.Nibintu bidafite uburozi, bisubirwamo bisubirwamo, cyane cyane bikoreshwa mubinyobwa bitandukanye, amazi yubutare hamwe nububiko bwa firime, kuri ubu bikoreshwa cyane kwisi kimwe mubikoresho bipakira.

Filime ya Mylar ni ubwoko bwa firime ya plastike ya polymer, kubera imiterere yayo yuzuye kandi ikundwa nabenshi mubayikoresha.Kubera ko umusaruro w’ubushinwa n’urwego rwa tekiniki bitagishoboye guhaza ibikenewe ku isoko, bamwe baracyakeneye kwishingikiriza ku bicuruzwa bitumizwa mu mahanga.

2, imiterere ya firime ya polyester

PET ni polymer ndende, ituruka kumyunyu ngugu ya etylene terephthalate.Glycol terephthalate iboneka mugusuzuma aside terephthalic na glycol.PET ni amata yera cyangwa yumuhondo yoroheje, polymer ya kirisiti cyane ifite ubuso bworoshye, burabagirana.

PET ifite ibintu byiza cyane (kurwanya ubushyuhe, kurwanya imiti).Imbaraga no gukomera, kubika amashanyarazi, umutekano, nibindi), bihendutse, bikoreshwa cyane nka fibre, firime, plastike yubuhanga, amacupa ya polyester nibindi.

PET ifite imiterere myiza yumubiri nubukanishi mubushuhe bwagutse, gukoresha igihe kirekire gukoresha ubushyuhe bugera kuri 120 ℃, kubika amashanyarazi meza, ndetse no mubushyuhe bwinshi ndetse numurongo mwinshi, ibikoresho byamashanyarazi biracyari byiza, ariko birwanya corona nabi, birwanya uburozi , guhangana nikirere, kurwanya imiti ihindagurika, kunyerera, kurwanya umunaniro, kurwanya ubukana, guhagarara neza ni byiza cyane.Kwinjiza amazi make, kurwanya aside idakomeye hamwe n’umuti ukomoka ku buhinzi, ariko ntibishobora kwihanganira kwibiza mu mazi, ntabwo birwanya alkali.

Mubisanzwe PET ni ibara ridafite ibara, firime yuzuye (uduce duto twongeweho noneho dushobora kongerwamo kugirango igire ibara), ibikoresho byiza bya mashini, gukomera cyane, gukomera no gukomera, kurwanya gucumita, kurwanya ubukana, ubushyuhe bwinshi nubushyuhe buke, kurwanya imiti, amavuta Kurwanya, guhumeka ikirere no kubungabunga impumuro nziza, nimwe mubintu bikunze gukoreshwa birwanya anti-penetration compte ya firime, ariko kurwanya corona ntabwo ari byiza.
