Intangiriro ngufi ku buryo bwo gukora ibikoresho bya PET
Intangiriro
Polyethylene Tereftalate, izwi cyane nka PET, ni ubwoko bwa pulasitiki bwabaye ingenzi cyane mu nganda zipakira. Izwiho imbaraga zayo, ubwisanzure, no kongera gukoreshwa, PET ikoreshwa cyane mu gukora amacupa yo kunywa, ibiryo, imiti n'ibindi bicuruzwa. Iyi blog itanga incamake y'uburyo amacupa ya PET akorwa, kuva ku bikoresho fatizo kugeza ku bicuruzwa byarangiye..
1. Gutunganya ibikoresho fatizo
Uburyo bwo gukora butangirana no gukora resin ya PET. PET ni polymer ikozwe muri aside terephtalike (TPA) na ethylene glycol (EG). Iyi miti yombi ikorwa na polymerization reaction kugira ngo ikore pellets za PET, ari na zo fatizo z'ibanze zo gukora ibikoresho bya PET.
2. Umusaruro wakozwe mbere y'igihe
Intambwe ikurikira muri iki gikorwa ni ugukora preforms. Preforms ni uduce duto twa PET, dufite ishusho nk'iy'umuyoboro w'igerageza, hanyuma tugashyirwa mu ishusho ya nyuma y'igikoresho cyatwo. Gukora preforms bikubiyemo:
（1）Kumisha ibinure by'amatungo: Udupira tw’amatungo twumishwa kugira ngo dukureho ubushuhe, ibyo bikaba byagira ingaruka ku bwiza bw’umusaruro wa nyuma.
(2) Gutera inshinge: Uduce twumye dushyirwa mu mashini ikoresha inshinge, aho dushongeshwa tugashyirwa mu bimera kugira ngo bikoremo ibimera. Hanyuma ibimera bikonjeshwa bigakurwa mu bimera.
3. Gutunganya ibihuha
Guhindura imiterere y'ibikoresho bya PET mu buryo bworoshye ni inzira aho ibikoresho bya PET bihinduka ibikoresho bya nyuma. Hari ubwoko bubiri bw'ingenzi bw'imikorere y'ibikoresho bya PET: ISBM (injection stretch blow molding) n'imashini ya extrusion blow molding (EBM).
Uburyo bwo gukurura inshinge (ISBM):
（1）Ubushyuhe: Imashini zikoreshwa mbere zishyushya ubushyuhe bwihariye kugira ngo zoroshye gukonja.
(2) Kurambura no gupfuka: Igipimo cy’imbere gishyushye gishyirwa mu ibumba. Agakoresho ko kugorora karakomeza mu gice cy’imbere, kakirambura uburebure bwacyo. Mu gihe kimwe, umwuka ushyushye cyane uhuha mu gice cy’imbere, ukakirambura kugira ngo gihuze n’imiterere y’ibumba.
（3）Gukonjesha: Igikoresho gishya cyakozwe gikonjeshwa hanyuma kigakurwa mu ibumba.
Uburyo bwo gukurura umwuka uva hanze (EBM):
（1） Gusohora: PET ishongeshejwe ishyirwa mu muyoboro witwa parison.
(2) Gutera: Ishusho ishyirwa mu ibumba igahuhwa n'umwuka kugira ngo ihuze n'imiterere y'ibumba.
（3）Gukonjesha: Icyo gikoresho gikonjeshwa hanyuma kigakurwa mu ibumba.
4. Igenzura ry'Ubuziranenge n'Isuzuma
Kugenzura ubuziranenge ni ingenzi mu gihe cyose cyo gukora kugira ngo ibikoresho bya PET byujuje ibisabwa. Hakorwa ibizamini bitandukanye kugira ngo harebwe imiterere nk'uburemere, ubwumvikane, n'ubudahangarwa bw'amazi. Hakoreshwa sisitemu zikora ku buryo bwikora n'igenzura ry'intoki kugira ngo hamenyekane kandi hakosorwe inenge iyo ari yo yose.
5. Gushyiramo ibirango no gupakira
Iyo ibikoresho bipimye ibizamini byo kugenzura ubuziranenge, bikomeza ku rwego rwo gushyiraho no gupakira. Ibirango bikoreshwa hakoreshejwe uburyo butandukanye, nko gushyiramo ibirango, gukoresha amaboko make, cyangwa gucapa mu buryo butaziguye. Ibikoresho bipakiye bigategurwa kugira ngo bikwirakwizwe.
Umwanzuro
Uburyo bwo gukora ibikoresho bya PET ni uruvange rutangaje rw'ubutabire n'ubuhanga. Kuva mu guhuza ibikoresho fatizo kugeza ku gupakira kwa nyuma, buri ntambwe yateguwe neza kugira ngo ikore ibikoresho byiza, byizewe kandi bitekanye. Kuba PET ikora ibintu byinshi kandi ishobora kongera gukoreshwa bituma iba amahitamo meza mu nganda nyinshi, bigaragaza akamaro k'ibikoresho mu bisubizo bigezweho byo gupakira.
Ibitekerezo bya nyuma
Gusobanukirwa inzira yo gukora ibikoresho bya PET ntibigaragaza gusa uburyo bigoye kandi bunoze burimo, ahubwo binashimangira akamaro ko guhanga udushya no gukomeza ibikorwa byo gupakira. Uko ikoranabuhanga rigenda ritera imbere, dushobora kwitega iterambere rirambye mu mikorere myiza no ku ngaruka ku bidukikije mu gukora ibikoresho bya PET.
