1. Ukwelashwa ngepulasitiki
Ngenxa yokuthi ama-macromolecule e-PET aqukethe amaqembu e-lipid futhi anezindawo ezithile ze-hydrophilic, okusanhlamvu kuyazwela emanzini lapho izinga lokushisa liphezulu.Lapho okuqukethwe kwamanzi kweqa umkhawulo, isisindo se-PET ye-molecular siyehla ekucutshungulweni, futhi imikhiqizo iba umbala futhi ibe brittle.
Ngakho-ke, ngaphambi kokucutshungulwa, izinto kufanele zomiswe, ngokushisa kokushisa kwe-150 ℃, amahora angaphezu kwama-4;ngokuvamile 170 ℃, 3-4 amahora.Indlela yomoya ingasetshenziswa ukuhlola ukomiswa okuphelele.Ingxenye yezinto ezigaywa kabusha ze-billet yebhodlela le-PET akufanele idlule u-25%, futhi izinto ezigaywe kabusha kufanele zomiswe kahle.
2. Ukukhethwa komshini wokubumba umjovo
Ngenxa yokuthi i-PET inesikhathi esifushane esizinzile ngemva kwephuzu lokuncibilika kanye nephuzu eliphakeme lokuncibilika, kuyadingeka ukukhetha uhlelo lomjovo olunezingxenye zokulawula izinga lokushisa ezengeziwe kanye nokukhiqiza okuncane kokuzikhukhumeza nokushisa ngesikhathi sokwenza ipulasitiki, kanye nesisindo sangempela somkhiqizo (kuhlanganise impahla yokuthatha amanzi) akufanele ibe ngaphansi kuka-2/3 yenani lomjovo lomshini.
3. Isikhunta nokuthulula isango lokuklama
Umbungu webhodlela le-PET, ovame ukwakhiwa ngesikhunta sesiteshi sokugeleza kokushisa, isikhunta kanye nesifanekiso somshini wokubumba umjovo phakathi kokungcono ukuba nepuleti lokufaka ukushisa, ugqinsi lwalo lungaba ngu-12mm, futhi ipuleti lokufaka ukushisa kufanele likwazi ukumelana nengcindezi ephezulu.Umbhobho okhipha umoya kufanele wanele ukugwema ukushisa ngokweqile noma ukuhlukana kwendawo, kodwa ukujula kwembobo yokukhipha umoya ngokuvamile akudluli u-0.03mm, ngaphandle kwalokho kulula ukukhiqiza uhlangothi olundizayo.
4. Izinga lokushisa elincibilikayo
Isilinganiso sendlela yokukhipha umoya etholakalayo, ububanzi obungu-270-295℃, ibanga elithuthukisiwe le-GF-PET lingasethwa ku-290-315℃, njll.
5. Ijubane lomjovo
Isivinini somjovo jikelele kufanele sisheshe ukuvimbela ukujiya ngaphambi kwesikhathi ngesikhathi sokujova.Kodwa ngokushesha okukhulu, izinga lokugunda liphezulu, yenza izinto zibe ntekenteke.Ukudubula kuvame ukuqedwa ngemizuzwana emi-4.
6. Ukucindezela emuva
Okuphansi kungcono, ukugwema ukuguga.Ngokujwayelekile ayidluli ku-100bar, ngokuvamile ayisetshenziswa.
7. Isikhathi sokuhlala
Ungasebenzisi isikhathi eside kakhulu sokugcina ukuze uvimbele ukwehla kwesisindo samangqamuzana, futhi zama ukugwema izinga lokushisa elingaphezu kuka-300 ℃.Uma ukuvala shaqa kungaphansi kwemizuzu eyi-15, yenza ukwelashwa kokudubula emoyeni kuphela;uma ngaphezu kwemizuzu engu-15, bese uhlanza nge-viscosity PE, bese uphonsa izinga lokushisa le-cylinder ekushiseni kwe-PE, kuze kube yilapho uqala kabusha.
8. Izinyathelo zokuphepha
Izinto zokubuyisela kabusha azikwazi ukuba zikhulu kakhulu, ngaphandle kwalokho, kulula ukukhiqiza "kwibhuloho" lezinto ezibonakalayo futhi kuthinte ukufakwa kwepulasitiki;
Uma ukulawulwa kwezinga lokushisa kwesikhunta kungalungile, noma ukulawulwa kwezinga lokushisa akufanelekile, kulula ukukhiqiza "inkungu emhlophe" ne-opaque;izinga lokushisa lesikhunta liphansi futhi lifana, isivinini sokupholisa ngokushesha, i-crystallization encane, khona-ke umkhiqizo ubonakala obala.
I-Huangyan Leiao Molding Co., Ltd. itholakala edolobheni lase-Huangyan District mold, e-Taizhou, esifundazweni sase-Taizhou, "okuyindawo yokuzalwa yase-Chinese mold".Le nkampani igxile kakhulu ekukhiqizeni isikhunta somjovo, inesipiliyoni seminyaka eminingi yesikhunta, ikakhulukazi ukukhiqiza kanye nokucutshungulwa kwesikhunta sombungu webhodlela, isikhunta sempahla ye-PET, isikhunta sesivalo sebhodlela, isikhunta semoto sangaphakathi kanye nesikhunta sokuhlobisa ngaphandle… … Isikhunta sinomklamo walo oyingqayizivele nobuchwepheshe bokucubungula, okusekelwe kumqondo othi "Ubuqotho bokuphathwa", namakhasimende asekhaya nakwamanye amazwe ukusungula ubudlelwano obuhle besikhathi eside sokubambisana, ngikholelwa ukuthi uLeiao uzobe ekufanele ukuthembela ekuhlanganyeleni. ibhizinisi.
