Indlela amabhodlela e-PET akhiwa ngayo

Amabhodlela e-PETyizitsha zepulasitiki ezenziwe ngezinto zepulasitiki ze-PET ngokucubungula isinyathelo esisodwa noma izinyathelo ezimbili. Amabhodlela e-PETibonakala ngesisindo sayo esilula, ukucaca okuphezulu, kanye nokumelana nokushaqeka nokuqhekeka.

i-PET ye lisiphakamiso bi-ottle, noma i-polyethylene terephthalate, ivame ukubizwa ngokuthi i-polyester. Igama layo lesiNgisi yi-Polyethylene Terephthalate, ekhiqizwa yi-polymerization reaction (condensation) yezinto ezimbili zokusetshenziswa zamakhemikhali: i-terephthalic acid (PTA) kanye ne-ethylene glycol (EG).

Izakhiwo zangaphambi Amabhodlela e-PETziyizinto ezibunjwe ngomjovo. Njengemikhiqizo eqediwe phakathi nendawo yokubumba i-biaxial stretch blowing elandelayo, intamo ye-preform isivele yakhekile ngesikhathi sesigaba sokubumba i-injection, futhi usayizi wayo ngeke ushintshe ngesikhathi sokushisa nokwelula/ukuvuthela. Usayizi, isisindo, kanye nobukhulu bodonga lwe-preform yizinto okudingeka siziqaphele kakhulu lapho sivuthela. Amabhodlela e-PET.

Ububanzi be lisiphakamiso bi-ottle Umlomo ongadlula uhlanganisa i-Ф18, Ф20, Ф22, Ф24, Ф28, Ф33, njll. (okuhambisana nobukhulu be-T bomlomo webhodlela), kanti imininingwane yentambo yesikulufu ivame ukuhlukaniswa ibe yi: 400, 410, 415 (okuhambisana nenani lokujika kwentambo yesikulufu). Ngokuvamile, sithi i-400 ingukujika okukodwa kwentambo yesikulufu, i-410 ingukujika okungu-1.5 kwentambo yesikulufu, kanti i-415 iyindawo ephezulu enezijika ezimbili zentambo yesikulufu.

Kanjani Amabhodlela e-PETzakhiwe:

Inqubo eqeda inqubo yokujova, ukwelula kanye nokuvuthela emshinini owodwa ibizwa ngokuthi indlela yesinyathelo esisodwa. Endleleni yesinyathelo esisodwa, ngemva kokufakwa kwe-preform, ukujova kuyabunjwa futhi kupholiswe, ukwelula kanye nokuvuthela lisiphakamiso bi-ottle isenzo siyakwenziwa. Izinzuzo zayo eziyinhloko ukonga amandla, ukukhiqiza okuphezulu, akukho ukungenelela ngesandla, kanye nokunciphisa ukungcola.

Indlela enezinyathelo ezimbili ihlukanisa umjovo kanye nokwelula kanye nokufuthalisiphakamiso bi-ottle, futhi izenza ngemishini emibili ngezikhathi ezahlukene, eyaziwa nangokuthi ukuvunguza ngomjovo lisiphakamiso bi-ottle inqubo. Esinyathelweni sokuqala, i-preform ibunjwa ngomjovo kusetshenziswa umshini wokubumba ngomjovo. Esinyathelweni sesibili, i-preform ekushiseni kwegumbi iyashiswa futhi yelulwe bese ifuthwa ngaphakathi. Amabhodlela e-PETIzinzuzo zendlela enezinyathelo ezimbili ukuthi ingathenga ama-preforms okufaka i-blow molding. Inganciphisa ukutshalwa kwezimali (kubasebenzi kanye nemishini). Umthamo we-preform mncane kakhulu kunowebhodlela, okwenza kube lula ukuthutha nokugcina. Ama-preforms akhiqizwa ngesikhathi sokuphumula angafuthwa. Amabhodlela e-PETngesikhathi sesikhathi esimatasa.

Amabhodlela e-PETzisetshenziswa kabanzi embonini yezimonyo, ikakhulukazi emikhakheni yokunakekelwa kwezinwele nokunakekelwa komzimba. Amabhodlela e-shampoo, i-body wash, i-toner, kanye namafutha okususa izimonyo konke kwenziwa nge-blow molding.
