BOPET Gahunda yo Gutunganya Filime: Incamake

Filime ya BOPET, izwi nka polyethylene terephthalate yerekanwe na biaxically, ni firime ya polyester yakozwe no kurambura polyethylene terephthalate (PET) mubyerekezo byayo bibiri byibanze kugirango ikore firime ikora ibintu byinshi.

Yakozwe na sosiyete yo mu Bwongereza ICI mu myaka ya za 1950.

Ifite inyungu nyinshi imbaraga zikomeye, imiterere yimiti nuburinganire, gukorera mu mucyo, kugaragariza, gaze hamwe nimbogamizi ya aroma, hamwe n’amashanyarazi.

Nyuma yimyaka yiterambere, ibicuruzwa byahindutse biva muri firime yumwimerere ya insulasiyo bigera kuri firime ya capacitor iriho ubu, firime yo gupakira, firime yerekana amafoto, nibindi.

Umubyimba wacyo urashobora kuva kuri 4.5um kugeza kuri 350 mm.

Ibikorwa byayo byateje imbere kandi kuva mubikorwa byoroshye bya keteti kugeza kurambura inshuro nyinshi no kurambura icyarimwe.

Imiterere yibicuruzwa nayo yagiye ihinduka kuva muri firime iringaniye ihinduka firime nyinshi, firime ishimangirwa, hamwe na firime.

Filime ya polyester yabaye imwe mubwoko bwa firime ikura vuba ku isoko.

Dehui FIlm numwe mubatanga firime ya bopet mubushinwa. Kugeza ubu, Turabibyaza umusaruro muburyo bubiri intambwe ebyiri zo kurambura. Hamwe no kwagura ingano yimikorere, ibisabwa byujuje ubuziranenge bwa firime ya polyester bigenda byiyongera. Kuduhatira kuzamura ireme no kwagura ibisohoka.

BOPET inzira yo gutunganya film

Noneho, reka tumenye inzira yo gutunganya bopet. Inzira rusange niyi ikurikira:

PET resin yumisha → gukuramo ibicuruzwa → kurambura igihe kirekire kumpapuro zibyibushye → kurambura guhinduranya → guhinduranya → gutemagura no gupakira → gutunganya byimbitse.

PET ishonga-yashizwemo urupapuro

Nyuma yo gushonga no gushiramo plasitike yumye ya PET yumye, hanyuma ikavangwa na filtre yuzuye kandi ikayungurura neza hamwe na mix mixer static, Ijyanwa mumutwe wimashini na pompe yo gupima. Noneho ukonjeshwa na roller yo kuzimya Mubice byimbitse kugirango ukoreshe.

Gukuramo ibice byombi

PET firime yuzuye Biaxial (icyerekezo) kurambura ni ukurambura firime cyangwa urupapuro rwakuwe muri extruder mubushyuhe runaka. Mubyerekezo birebire kandi bihinduranya kugirango ukore urunigi.

Isura ya kristu igomba kugenwa ireba, hanyuma kuvura ubushyuhe bukorwa mugihe cyo kurambura.

Filime irambuye ya biaxial, kubera icyerekezo cyibice bya molekile, itezimbere kristu.

Irashobora rero kongera imbaraga zingirakamaro, modulus ya elastique ya tensile, imbaraga zingaruka, imbaraga zamarira, kunoza ubukonje, gukorera mu mucyo, guhumeka neza, gukwirakwiza amashanyarazi, hamwe nuburabyo.

Byinshi muri firime iringaniye ifata indege ubwoko bwikurikiranya biaxial kurambura inzira.
