Icupa rya Shampoo y'amatungo

2026-01-30

Iyo dufashe icupa rya shampoo rikoreshwa cyane, hazaba hari icyapa cya PET hepfo y'icupa, kigaragaza ko iki gicuruzwa ari icupa rya PET. Amacupa ya PET akoreshwa cyane mu nganda zishinzwe kwita ku buzima bw'umuntu kandi ahanini aba afite ubushobozi bunini. Amacupa ya PET ni ibikoresho bya pulasitiki biboneka binyuze mu gutunganya ibikoresho bya PET binyuze mu ntambwe imwe cyangwa ebyiri. Plasitike ya PET ifite imiterere yo kuba yoroshye, ibonerana cyane, kandi irwanya kwangirika no kuvunika.

PET, cyangwa polyethylene terephthalate, izwi kandi nka polyester. Izina ryayo ry'Icyongereza ni Polyethylene Terephthalate, ikorwa n'uburyo bwo gupima (condensation) bw'ibikoresho bibiri by'umwimerere: aside terephthalate (PTA) na ethylene glycol (EG). Preforms ni ibintu byabumbwe mu inshinge. Nk'ikintu cyo hagati cyarangiye mu gukurura no gukaraba biaxial nyuma, ijosi ry'inshinge rihinduka mu gihe cyo gukaraba, kandi ingano yaryo ntizahinduka mu gihe cyo gushyushya no gukaraba/gukaraba. Ingano, uburemere, n'ubugari bw'urukuta rwa preform ni ibintu bigomba kwitabwaho cyane mu gihe cyo gukaraba icupa.

Mu gutegura amacupa yabumbwe n'ibinyabutabire, uduce twa PET tubanza gushyirwa mu icupa ryabumbwe. Bisabwa ko igipimo cy'ibikoresho byabumbwe n'ibinyabutabire ntibigomba kuba hejuru cyane (munsi ya 5%), kandi igihe cyo kongera gukoresha ntibigomba kurenza bibiri. Uburemere bwa molekile n'ubucucike ntibigomba kuba biri hasi cyane (uburemere bwa molekile 31.000 - 50.000, ubucucike bw'imbere 0.78 - 0.85 cm³/g). Dukurikije Itegeko ry'Igihugu ry'Umutekano w'Ibiribwa, ibikoresho byabumbwe n'ibinyabutabire birabujijwe gukoreshwa mu gupakira ibiryo n'imiti. Ibinyabutabire byabumbwe n'ibinyabutabire bigomba kubikwa amasaha arenga 24 mbere yo gukoreshwa. Ibinyabutabire bitakoreshejwe nyuma yo gushyushya bigomba kubikwa amasaha arenga 48 mbere yo kongera gushyushya. Igihe cyo kubika amacupa ntigikwiye kurenza amezi atandatu. Ubwiza bwa preform ahanini buterwa n'ubwiza bw'ibikoresho bya PET, bityo ni ngombwa guhitamo ibikoresho byoroshye gukurura no gukora, no guteza imbere uburyo bwo gushushanya bwa preform bukwiye. Igerageza ryerekana ko ibikoresho byakozwe mu bikoresho fatizo bitumizwa mu mahanga bifite ubukana bumwe byoroshye gukurura ifuro kurusha ibyakozwe mu bikoresho fatizo byo mu rugo. Ariko, ku itsinda rimwe ry’ibikoresho byakozwe mu buryo butandukanye, amatariki atandukanye yo gukora ashobora gusaba uburyo butandukanye bwo gukurura ifuro. Ubwiza bw’ibikoresho byakozwe mu buryo butandukanye ni bwo butuma uburyo bwo gukurura ifuro bugorana. Ibisabwa kuri ibyo bikoresho ni ubuziranenge, ubwisanzure, nta mwanda, nta ibara, uburebure bukwiye bwo gukurura ifuro, n’akazu kayikikije.

Amacupa y’ibikoresho bya PP na PE ahanini aba afite amabara akomeye, mu gihe ibikoresho bya PETG, PET, na PVC akenshi biba bifite ibara ribonerana cyangwa ribonerana rifite isura isobanutse kandi irabagirana, kandi amabara akomeye ntabwo akoreshwa kenshi. Amacupa y’ibikoresho bya PET ashobora kandi gusigwa irangi. Hari ahantu hanini h’icupa ryakozweho ibara, rirushaho kuba ryiza cyane iyo umucyo ugeze. Igice cyo hasi cy’icupa ryakozweho injection-blow gifite umurongo wo guhuza. Ibikoresho by’ingenzi by’amacupa yakozweho ibara birimo ibifunga by’imbere (bikunze gukoreshwa ku bikoresho bya PP na PE), imipfundikizo yo hanze (ikunze gukoreshwa kuri PP, ABS, na acrylic, kandi biboneka mu bikoresho bya elegitoroniki, electro-galvanized, na spray-rangi, bikunze gukoreshwa ku macupa ya toner), imipfundikizo y’umutwe wa pompe (ikunze gukoreshwa mu gukora essence na lotion), imipfundikizo, n’imipfundikizo (bikunze gukoreshwa mu miyoboro minini ya chemical ikoreshwa buri munsi).
