Iriburiro: Iyo dufashe icupa risanzwe rya shampoo, hazaba ikirango cya PET hepfo y icupa, bivuze ko iki gicuruzwa ari icupa rya PET. Amacupa ya PET akoreshwa cyane mubikorwa byo gukaraba no kwitaho kandi ahanini bifite ubushobozi bunini. Muri iyi ngingo, turamenyekanisha cyane icupa rya PET nkigikoresho cya plastiki.
Amacupa ya PET ni ibikoresho bya pulasitike bikozwe muri PETibikoresho bya pulasitikiunyuze mu ntambwe imwe cyangwa intambwe ebyiri. PET plastike ifite ibiranga uburemere bworoshye, gukorera mu mucyo mwinshi, kurwanya ingaruka kandi ntibyoroshye kumeneka.
Uburyo bwo gukora
1. Sobanukirwa na preform
Preform nigicuruzwa cyatewe inshinge. Nkigicuruzwa giciriritse cyarangije kugurishwa nyuma ya biaxial kurambura, icyuho cya preform cyarangiye mugihe cyo gutera inshinge, kandi ubunini bwacyo ntibuzahinduka mugihe cyo gushyushya no kurambura / guhuha. Ingano, uburemere, nubukuta bwurukuta rwa preform nibintu dukeneye kwitondera cyane mugihe duhuha amacupa.
A. Imiterere y'icupa
B. Icupa rya emboro
2. PET icupa
Uburyo bumwe
Inzira yo kurangiza inshinge, kurambura no kuvuza mumashini imwe yitwa inzira imwe. Uburyo bumwe bwintambwe nugukora kurambura no guhuha nyuma ya preform ikonje nyuma yo guterwa inshinge. Ibyiza byingenzi ni ukuzigama ingufu, umusaruro mwinshi, nta murimo wamaboko no kugabanya umwanda.
Uburyo bubiri
Uburyo bwintambwe ebyiri butandukanya inshinge no kurambura no kuvuza, kandi bikabikora kumashini ebyiri mugihe gitandukanye, bizwi kandi nko kurambura no guterwa. Intambwe yambere nugukoresha imashini itera inshinge kugirango utere preform. Intambwe ya kabiri ni ugushyushya ubushyuhe bwicyumba preform hanyuma ukarambura ukajugunya mu icupa. Ibyiza byuburyo bubiri ni ukugura preform yo guhumeka. Irashobora kugabanya ishoramari (impano nibikoresho). Ingano ya preform ni nto cyane kurenza icupa, ryoroshye gutwara no kubika. Preform yakozwe mugihe cyigihe kitari gito irashobora gutwarwa mumacupa mugihe cyimpera.
3. PET uburyo bwo kubumba amacupa
1. PET ibikoresho:
PET, polyethylene terephthalate, bita polyester. Izina ry'icyongereza ni Polyethylene Terephthalate, ikorwa na polymerisation reaction (condensation) y'ibikoresho bibiri bibisi bya shimi: terephthalic aside PTA (aside terephthalic) na Ethylene glycol EG (Ethylicglycol).
2. Ubumenyi busanzwe kubyerekeye umunwa w'icupa
Umunwa w'icupa ufite umurambararo wa Ф18, Ф20, Ф22, Ф24, Ф28, Ф33 (uhuye n'ubunini bwa T umunwa w'icupa), kandi ibisobanuro byinsanganyamatsiko birashobora kugabanywamo: 400, 410, 415 (bihuye numubare wa umurongo uhinduka). Muri rusange, 400 ni 1 ihinduranya, 410 ni 1.5 ihinduranya, naho 415 ni imirongo 2 yo hejuru.
3. Umubiri w'icupa
Amacupa ya PP na PE ahanini ni amabara akomeye, PETG, PET, PVC ahanini iragaragara, cyangwa ibara kandi iragaragara, hamwe no kumva neza, kandi amabara akomeye ntabwo akoreshwa gake. Amacupa ya PET arashobora kandi guterwa. Hano hari ingingo ya convex hepfo yumucupa wacuzwe. Irabagirana munsi yumucyo. Hano hari umurongo uhuza hepfo y icupa ryatewe.
4. Guhuza
Ibicuruzwa nyamukuru bihuye nibicupa-amacupa ni ibyuma byimbere (bikunze gukoreshwa mubikoresho bya PP na PE), imipira yinyuma (ikunze gukoreshwa kuri PP, ABS na acrylic, nayo amashanyarazi, hamwe na aluminiyumu yamashanyarazi, ahanini ikoreshwa muri spray toner), igipfukisho cyumutwe wa pompe .
Gusaba
Amacupa ya PET akoreshwa cyane mubikorwa byo kwisiga,
cyane mu nganda zo gukaraba no kwita,
harimo shampoo, amacupa ya gel gel, toner, amacupa yo gukuramo marike, nibindi.
Byose byavuzwe.
Kugura ibitekerezo
1. PET ni kimwe gusa mubikoresho biboneka kumacupa. Hariho kandi amacupa ya PE (yoroshye, amabara menshi akomeye, inshuro imwe) ikoreshwa mu Bushinwa, igiciro kinini, imyanda myinshi, gukora inshuro imwe, ibikoresho bidasubirwaho), amacupa ya PVC (birakomeye, ntabwo byangiza ibidukikije, bitagaragara neza kurusha PET, ariko birasa kurusha PP na PE)
2. Ibikoresho byintambwe imwe bihenze, ibikoresho byintambwe ebyiri birahendutse
3. PET icupa ryamacupa rihendutse.
