Amacupa y'ibinyobwa yahinduwe amacupa ya PET avanze na polyethylene naphthalate (PEN) cyangwa amacupa akomatanya ya PET hamwe na polyoparike ya termoplastique.Bashyizwe mu macupa ashyushye kandi birashobora kwihanganira ubushyuhe buri hejuru ya 85 ° C;Amacupa yamazi ni amacupa akonje, ntagisabwa kugirango arwanye ubushyuhe.Icupa rishyushye risa nicupa rikonje muburyo bwo gukora.
1. Ibikoresho
Kugeza ubu, abakora PET imashini ikora imashini itumiza cyane itumizwa muri SIDEL yo mu Bufaransa, KRONES yo mu Budage, na Fujian Quanguan yo mu Bushinwa.Nubwo abayikora batandukanye, amahame yibikoresho byabo arasa, kandi muri rusange harimo ibice bitanu byingenzi: sisitemu yo gutanga fagitire, sisitemu yo gushyushya, sisitemu yo kuvuza amacupa, sisitemu yo kugenzura n’imashini zifasha.
2. Hisha uburyo bwo kubumba
PET icupa ryerekana uburyo bwo kubumba.
Ibintu byingenzi bigira ingaruka kumacupa ya PET yogukora ni preform, gushyushya, kubanza guhuha, kubumba no kubyaza umusaruro.
2.1
Mugihe utegura amacupa yacuzwe, chip ya PET ni inshinge zabanje kubumbabumbwa.Irasaba ko igipimo cyibikoresho bya kabiri byagaruwe bidashobora kuba hejuru cyane (munsi ya 5%), inshuro zo gukira ntizishobora kurenga kabiri, kandi uburemere bwa molekile hamwe nubukonje ntibishobora kuba bike cyane (uburemere bwa molekile 31000- 50000, ubwiza bwimbere 0.78 -0,85cm3 / g).Dukurikije amategeko y’igihugu y’umutekano w’ibiribwa, ibikoresho byo kugarura kabiri ntibishobora gukoreshwa mu biribwa no gupakira imiti.Gutera inshinge zabugenewe zirashobora gukoreshwa kugeza 24h.Imikorere itakoreshejwe nyuma yo gushyushya igomba kubikwa mumasaha arenga 48 kugirango ishyushye.Igihe cyo kubika preforms ntigishobora kurenza amezi atandatu.
Ubwiza bwa preform buterwa ahanini nubwiza bwibikoresho bya PET.Ibikoresho byoroshye kubyimba kandi byoroshye gushushanya bigomba gutoranywa, kandi uburyo bukwiye bwo kubumba bigomba gukorwa.Ubushakashatsi bwerekanye ko ibicuruzwa bitumizwa mu mahanga bikozwe mu bikoresho bya PET bifite ubwiza bumwe byoroshye guhumeka neza kuruta ibikoresho byo mu rugo;mugihe icyiciro kimwe cya preforms gifite amatariki yumusaruro atandukanye, inzira yo guhanagura nayo irashobora kuba itandukanye cyane.Ubwiza bwa preform bugena ingorane zo gutondeka.Ibisabwa kuri preform ni ubuziranenge, gukorera mu mucyo, nta mwanda, nta bara, n'uburebure bw'aho batera inshinge na halo ikikije.
2.2 Gushyushya
Gushyushya preform birangizwa nitanura ryubushyuhe, ubushyuhe bwarwo bushyirwaho intoki kandi bigahinduka neza.Mu ziko, itara rya farashi ya farumasi iratangaza ko infragre ya kure ishyushya preform, kandi umuyaga uri munsi yitanura uzenguruka ubushyuhe kugirango ubushyuhe buri imbere mu ziko ndetse.Imikorere izunguruka hamwe mukugenda imbere mu ziko, kuburyo inkuta za preforms zishyuha kimwe.
Gushyira amatara mu ziko muri rusange ni muburyo bwa "zone" kuva hejuru kugeza hasi, hamwe nimpera nyinshi kandi hagati.Ubushyuhe bw'itanura bugenzurwa numubare wugurura itara, ubushyuhe rusange, ubushyuhe bwamashyiga hamwe nubushyuhe bwa buri gice.Gufungura itara ryamatara bigomba guhinduka bifatanije nicupa ryabanjirije.
Kugira ngo ifuru ikore neza, guhindura uburebure bwayo, isahani ikonje, nibindi nibyingenzi.Niba ihinduka ridakwiriye, biroroshye kubyimba umunwa w'icupa (umunwa w'icupa riba rinini) n'umutwe ukomeye n'ijosi (ibikoresho byo mu ijosi ntibishobora gukururwa) mugihe cyo kubumba N'izindi nenge.
2.3
Mbere yo kuvuza ni intambwe yingenzi muburyo bubiri bwo gucupa icupa.Yerekeza kuri pre-blowing itangira iyo gushushanya umurongo umanutse mugihe cyo guhanagura, kugirango preform ifate imiterere.Muri iki gikorwa, icyerekezo kibanziriza icyerekezo, mbere yo guhuha no gutemba ni ibintu bitatu byingenzi.
Imiterere yuburyo bwa icupa mbere yo guhanagura igena ingorane zuburyo bwo guhumeka hamwe nubwiza bwimikorere y icupa.Imiterere isanzwe icupa ryamacupa rimeze nkizunguruka, kandi ridasanzwe ririmo imiterere-yinzogera nuburyo bwo gufata.Impamvu yimiterere idasanzwe nubushuhe budakwiye, ubushyuhe budahagije mbere yo guhuha cyangwa gutemba, nibindi. Ingano y icupa ryabanje guterwa biterwa nigitutu kibanziriza guhuha hamwe nicyerekezo kibanziriza.Mu musaruro, ingano n'imiterere y'amacupa yose mbere yo guhanagura mubikoresho byose bigomba kubikwa muri rusange.Niba hari itandukaniro, impamvu zirambuye zigomba kuboneka.Uburyo bwo gushyushya cyangwa mbere yo guhuha burashobora guhinduka ukurikije uko icupa ryabanjirije.
Ingano yumuvuduko ubanziriza guhuha iratandukanye nubunini bwicupa nubushobozi bwibikoresho.Mubisanzwe, ubushobozi ni bunini kandi igitutu kibanziriza ni gito.Ibikoresho bifite ubushobozi bwo kubyara umusaruro mwinshi hamwe nigitutu kinini.
2.4 Imashini ifasha nububiko
Imashini ifasha cyane cyane ibikoresho bikomeza ubushyuhe burigihe.Ubushyuhe buhoraho bwububiko bugira uruhare runini mukubungabunga ibicuruzwa.Mubisanzwe, icupa ryumubiri ubushyuhe buri hejuru, naho icupa ryubushyuhe bwo hasi.Ku macupa akonje, kubera ko ingaruka zo gukonjesha hepfo zigena urugero rwerekezo rwa molekile, nibyiza kugenzura ubushyuhe kuri 5-8 ° C;n'ubushyuhe buri munsi y'icupa rishyushye ni hejuru cyane.
2.5 Ibidukikije
Ubwiza bwibidukikije butanga umusaruro nabwo bugira uruhare runini muguhindura inzira.Ubushyuhe butajegajega burashobora kugumana ihame ryibikorwa no guhagarara kwibicuruzwa.PET icupa ryibumba ni byiza mubushyuhe bwicyumba nubushuhe buke.
3. Ibindi bisabwa
Icupa ryumuvuduko rigomba kuba ryujuje ibisabwa mugupimisha hamwe no gupima igitutu hamwe.Ikizamini cyo guhangayika ni ukurinda kumeneka no gutemba k'urunigi rwa molekile mugihe cyo guhura hagati y icupa na lubricant (alkaline) mugihe cyo kuzuza icupa rya PET.Ikizamini cyumuvuduko nukwirinda kuzuza icupa.Kugenzura ubuziranenge nyuma yo guturika gaze ya gaze.Kugirango uhaze ibyo byombi bikenewe, uburebure bwikibanza bugomba kugenzurwa murwego runaka.Muri rusange imiterere ni uko ingingo yo hagati ari ntoya, ikizamini cyo guhangayika ni cyiza, kandi kurwanya igitutu ni bibi;ingingo yo hagati irabyimbye, ikizamini cyumuvuduko nicyiza, kandi ikizamini cya stress ni kibi.Birumvikana ko ibisubizo byikizamini cya stress nabyo bifitanye isano rya bugufi no kwegeranya ibintu mumwanya winzibacyuho ukikije point point, bigomba guhinduka ukurikije uburambe bufatika.
4. Umwanzuro
Guhindura icupa rya PET icupa ryibikorwa bishingiye kumibare ijyanye.Niba amakuru ari mabi, ibisabwa mubikorwa birakomeye, kandi biragoye no guhanagura amacupa yujuje ibyangombwa.
