Ama-preforms ebhodlela le-PET ayimikhiqizo ejwayelekile yokubumba umjovo, kulula ukuyihambisa, iningi lenziwe ngepulasitiki, elinokuthungwa okufanayo kanye nokufakwa kahle.Ziwumkhiqizo ophakathi wamabhodlela epulasitiki nemiphongolo kawoyela.Ngaphansi kokushisa okuthile nokucindezela, isikhunta sigcwele izinto zokusetshenziswa, futhi ngaphansi kokucutshungulwa komshini wokubumba umjovo, kucutshungulwa ku-preform yebhodlela enobukhulu obuthile nokuphakama okuhambisana nesikhunta.I-Polyethylene terephthalate iyinhlobonhlobo ebaluleke kakhulu ye-thermoplastic polyester.Igama layo lesiNgisi yi-Polythylene terephthalate, efushanisiwe njenge-PET noma i-PETP (kamuva ebizwa ngokuthi i-PET), eyaziwa ngokuthi i-polyester resin.I-polymer ye-condensation ye-terephthalic acid ne-ethylene glycol.Kanye ne-PBT, ngokuhlanganyela ibizwa ngokuthi i-thermoplastic polyester, noma i-polyester egcwele.I-PET iyi-polymer emhlophe e-milky noma ephuzi ecwebe kakhulu enendawo ebushelelezi futhi ecwebezelayo.Inokumelana nokunyakaza okuhle, ukumelana nokukhathala, ukumelana nokungqubuzana nokuzinza kohlangothi, ukuguga okuphansi kanye nobulukhuni obuphakeme, futhi inokuqina okukhulu phakathi kwe-thermoplastics;izakhiwo ezinhle zokuvikela ugesi, ezithintwa kancane izinga lokushisa, kodwa ukumelana ne-corona okubi.Ayinabuthi, imelana nesimo sezulu, izinzile kumakhemikhali, ukumuncwa kwamanzi aphansi, imelana nama-asidi abuthakathaka nezincibilikisi zemvelo.
Amabhodlela e-PET avame ukusetshenziselwa ukupakisha, futhi ukupakishwa kuvame ukupakishwa ezendlalelo ngesikhathi sokuthutha noma i-inventory.Ngalesi sikhathi, sizocubungula ukubekezelelana kwengcindezi kwesendlalelo esiphansi kakhulu.Ngesikhathi sokuhlolwa kwengcindezi yebhodlela le-PET, beka ibhodlela le-PET kumapuleti amabili okucindezela avundlile omshini, qala umshini wokucindezela ibhodlela le-PET we-Suzhou Ou Instruments, futhi amapuleti okucindezela amabili azocindezelwa ngesivinini esithile sokuhlola.Uma ilayisha, ithuluzi liyama futhi lilondoloze idatha.Ukuhlolwa okujwayelekile kwamabhodlela e-PET kufaka phakathi ukuhlolwa kokuqina kodonga lwebhodlela, ukuhlolwa kokumelana nengcindezi, nokuhlolwa kokukhathala kokuvula isivalo sebhodlela.Abakhiqizi be-PET baneminyango yabo yokuhlola ikhwalithi.Amabhodlela e-PET anokusebenza okuqinile futhi asetshenziswa kabanzi ezidingweni zansuku zonke, ukupakishwa kwamakhemikhali kwansuku zonke kanye neminye imikhakha.Kusukela ekusetshenzisweni kwesikhunta kuya emishinini nasezinsizeni, zikhethwa kakhulu.Kulula ukuqalisa kodwa kunzima ukukwazi kahle.Ama-preforms ebhodlela le-PET acutshungulwa futhi ngokubumba ibhodlela ukuze enze amabhodlela epulasitiki, okuhlanganisa amabhodlela asetshenziselwa ukupakisha izimonyo, imithi, ukunakekelwa kwezempilo, iziphuzo, amanzi amaminerali, ama-reagents, njll. Le ndlela yokwenza ibhodlela ibizwa ngokuthi indlela yezinyathelo ezimbili, okungukuthi, i-preform yebhodlela yakhiwa ngokubumba umjovo, bese kuba Indlela yokwenza amabhodlela epulasitiki e-PET ngokusebenzisa ukubunjwa kokushaywa.
