I-EVA (i-ethylene vinyl acetate copolymer) iyimpahla yepulasitiki esetshenziswa kakhulu enokucutshungulwa okuhle kakhulu kanye nezakhiwo ezibonakalayo, ngakho isetshenziswa kabanzi emikhakheni ehlukahlukene. Khona-ke, izindlela ezifanele zeEVAukucubungula kuzokwethulwa ngokulandelayo, okuhlanganisa i-extrusion, ukubumba umjovo, i-calendering nokucindezela okushisayo.
1. Indlela yokukhipha
I-Extrusion iyindlela evamile yokucubungula ye-EVA. Izinhlayiya ze-EVA ziyashiswa futhi zincibilike bese i-EVA encibilikile ikhishwa nge-extruder. Le ndlela ifaneleka ekukhiqizeni imikhiqizo ye-EVA yobujamo obuhlukahlukene, njengamapuleti, amapayipi, amaphrofayili, njll. Indlela ye-extrusion inezinzuzo zokusebenza kahle kokukhiqiza okuphezulu kanye nezindleko eziphansi, ngakho-ke isetshenziswa kabanzi ekukhiqizeni izimboni.
2. Indlela yokubumba umjovo
Indlela yokubumba umjovo ukujova i-EVA encibilikisiwe esibunjeni, futhi ngokupholisa nokuqiniswa kwesikhunta, kutholakala imikhiqizo ye-EVA edingekayo. Indlela yokubumba umjovo ilungele ukukhiqiza imikhiqizo ye-EVA emise okwezimo eziyinkimbinkimbi, njengamatheni, izingxenye, njll. Le ndlela inezinzuzo zomjikelezo omfushane wokukhiqiza kanye nekhwalithi yomkhiqizo ozinzile, ngakho-ke ivame ukusetshenziswa ekukhiqizeni izimboni.
3. Indlela yekhalenda
Indlela ye-calender iwukukhipha ngokuqhubekayo kanye ne-calender i-EVA encibilikisiwe ngekhalenda ukuze ipholise ngokushesha ibe yisimo sefilimu. Le ndlela ilungele ukukhiqizwa kwamafilimu e-EVA, amafilimu okupakisha neminye imikhiqizo. Indlela ye-calendering inezinzuzo zesivinini sokukhiqiza okusheshayo nokufana okuhle komkhiqizo, ngakho-ke isetshenziswa kabanzi embonini yokupakisha.
4. Indlela yokucindezela okushisayo
Indlela yokucindezela okushisayo ukubeka ishidi le-EVA elincibilikisiwe libe yisikhunta, futhi liqiniswe ngokushisa nokucindezela kwesikhunta. Le ndlela ilungele ukukhiqizwa kwama-insoles e-EVA, izipontshi ze-EVA neminye imikhiqizo. Ukucindezela okushisayo kunezinzuzo zokunemba okuphezulu kokubumba kanye nekhwalithi enhle yomkhiqizo, ngakho-ke kusetshenziswa kakhulu ezintweni zezicathulo, ukuhlinzeka ngendlu kanye nezinye izimboni.
Ukufingqa, izindlela zokucubungula ze-EVA zifaka i-extrusion, ukubumba umjovo, ukufakwa kwekhalenda nokucindezela okushisayo. Izindlela ezihlukene zokucubungula zifanele imikhiqizo ehlukene. Ukukhetha indlela yokucubungula efanele kungathuthukisa ukusebenza kahle kokukhiqiza kanye nekhwalithi yomkhiqizo. Ekusebenzeni kwangempela, kuyadingeka ukukhetha indlela efanele yokucubungula ngokwezidingo zomkhiqizo nezimo zokukhiqiza, futhi wenze izinguquko ezihambisanayo zenqubo kanye nokukhetha kwemishini. Ngokuqhubeka nokwenza ngcono izindlela zokucubungula, ukusebenza nokuncintisana kwemikhiqizo ye-EVA kungathuthukiswa ukuze kuhlangatshezwane nesidingo semakethe.
