Uburyo amacupa ya PET akorwa
Amacupa ya PETni ibikoresho bya pulasitiki bikozwe mu bikoresho bya PET binyuze mu gutunganya intambwe imwe cyangwa ebyiri. PET pulasitiki yo Amacupa ya PETirangwa n'uburemere bwayo bworoshye, ubwisanzure buhanitse, no kudahura n'ingaruka cyangwa gusenyuka.
PET ya ligitekerezo binyoni, cyangwa polyethylene terephthalate, ikunze kwitwa polyester. Izina ryayo ry'Icyongereza ni Polyethylene Terephthalate, ikorwa n'uburyo bwo gupima (condensation) bw'ibikoresho bibiri by'ibanze: aside terephthalate (PTA) na ethylene glycol (EG).
Imiterere ya mbere ya Amacupa ya PETni ibintu byakozwe mu buryo bwa injection-molding. Nk'ibikoresho birangira neza byo gukoresha mu buryo bwa kabiri, ijosi ry'injection rimaze gukorwa mu gihe cyo gushyushya injection, kandi ingano yaryo ntizahinduka mu gihe cyo gushyushya no kurambura/gutera. Ingano, uburemere, n'ubugari bw'urukuta rw'injection ni ibintu tugomba kwitondera cyane mu gihe cyo gutera injection. Amacupa ya PET.
Ingano ya ligitekerezo binyoni Umunwa ushobora kunyuramo urimo Ф18, Ф20, Ф22, Ф24, Ф28, Ф33, nibindi (bihuye n'ingano ya T y'umunwa w'icupa), kandi ibipimo by'umugozi w'icupa bikunze kugabanywamo: 400, 410, 415 (bihuye n'umubare w'imigozi y'icupa). Muri rusange, tuvuga ko 400 ari uguhindukira 1 kw'umugozi w'icupa, 410 ari uguhindukira 1.5 kw'umugozi w'icupa, naho 415 ni umwanya wo hejuru ufite imigozi y'icupa inshuro 2.
Uburyo Amacupa ya PETbyakozwe:
Uburyo burangiza uburyo bwo gutera, kunagura no gusohora mu mashini imwe bwitwa uburyo bw'intambwe imwe. Mu buryo bw'intambwe imwe, nyuma yo gutera inshinge, kurambura no gusohora inshinge bitegurwa bigakonjeshwa, ligitekerezo binyoni ibikorwa birakorwa. Ibyiza byayo by'ingenzi ni ukuzigama ingufu, umusaruro mwinshi, nta gikorwa n'intoki, no kugabanya umwanda.
Uburyo bw'intambwe ebyiri butandukanya gutera inshinge no kunanura no guhumekaligitekerezo binyoni, kandi ibikora mu mashini ebyiri mu bihe bitandukanye, izwi kandi nka injection-stretch-blowing ligitekerezo binyoni inzira. Mu ntambwe ya mbere, preform ikorwa hakoreshejwe imashini ikora inshinge. Mu ntambwe ya kabiri, preform iri ku bushyuhe bw'icyumba irasubirwamo ikanaramburwa hanyuma igahuhwa mu Amacupa ya PETIbyiza by'uburyo bw'intambwe ebyiri ni uko bushobora kugura preforms zo gukoresha mu gukaraba. Bushobora kugabanya ishoramari (mu bakozi n'ibikoresho). Ingano ya preform ni nto cyane ugereranyije n'iy'icupa, bigatuma byoroshye gutwara no kubika. Preforms zikorwa mu gihe cy'ikiruhuko zishobora guturitswa mu Amacupa ya PETmu gihe cy'izamuka ry'ibiciro.
Amacupa ya PETzikoreshwa cyane mu nganda z'ubwiza, cyane cyane mu bijyanye no kwita ku musatsi no kwita ku mubiri. Amacupa yo gukoresha shampoo, isuku yo mu mubiri, ikoreshwa mu gukaraba, n'amavuta yo gukuraho amavuta yo kwisiga byose bikorwa hakoreshejwe uburyo bwo gukaraba.
