Ezweni elikhulu lokupakishwa kokudla, okuthambileukupakisha ifilimu rolliwine ukuthandwa yimakethe esabalele ngenxa yokungasindi kwayo, yinhle, futhi kulula ukuyicubungula izici zayo. Kodwa-ke, ngenkathi siphishekela ukuqanjwa kabusha kwedizayini kanye nobuhle bokupakisha, sivamise ukungakunaki ukuqonda kwezici zezinto zokupakisha ngokwazo. Namuhla, ake sembule imfihlakalo yefilimu yokupakisha ethambile futhi sihlole indlela yokufinyelela ukuqonda okuthulile ngama-substrates angaphansi edizayini yesakhiwo sokupakisha, okwenza ukupakisha kulunge kakhulu.
Amagama afushanisiwe nezici ezihambisanayo zamapulasitiki
Okokuqala, kudingeka sibe nokuqonda okuyisisekelo kwezinto ezisetshenziswa kakhulu zepulasitiki. Kumafilimu okupakisha okuthambile okudla, izinto ezivamile zepulasitiki zihlanganisa i-PE (i-polyethylene), i-PP (i-polypropylene), i-PET (i-polyethylene terephthalate), i-PA (inayiloni), njll. Into ngayinye inezici zayo eziyingqayizivele zomzimba namakhemikhali, njengokusobala, amandla, izinga lokushisa. ukumelana, ukusebenza kwesithiyo, njll.
I-PE (i-polyethylene): Lena into evamile yepulasitiki enokukhanya okuhle nokuvumelana nezimo, kuyilapho futhi inezindleko eziphansi. Kodwa-ke, ukumelana kwayo nezinga lokushisa akulungile futhi akufanelekile ukupakisha ukudla okuphekiwe noma okuqandisiwe emazingeni aphezulu okushisa.
I-PP (i-polypropylene): Impahla ye-PP inokumelana nokushisa okuphezulu futhi ingamelana namazinga okushisa aphezulu ngaphandle kokuguqulwa, ngakho-ke ivame ukusetshenziswa ekufakweni kokudla okudinga ukushiswa noma iqhwa.
I-PET (i-polyethylene terephthalate): Izinto ze-PET zinokubonakala okuhle kakhulu namandla, kanye nokumelana okuhle kwezinga lokushisa kanye nezakhiwo zokuvimbela, ngakho-ke zivame ukusetshenziswa ekufakweni kokudla okudinga ukucaca okuphezulu namandla.
I-PA (Nylon): Impahla ye-PA inezindawo ezinhle kakhulu zokuthibela, ezingavimbela ngempumelelo ukungena komoyampilo namanzi, futhi igcine ubusha bokudla. Kepha uma kuqhathaniswa nezinye izinto, izindleko ze-PA ziphezulu.
Ungakhetha kanjani fizinto zokupakisha ood
Ngemva kokuqonda izici zezinto ezihlukahlukene zepulasitiki, singakhetha izinto ezifanele zokwakheka kwesakhiwo sokupakisha ngokusekelwe ezicini nasezidingweni zomkhiqizo. Ngesikhathi esifanayo, lapho ukhetha ama-substrates wokuphrinta, ukufaneleka kokuphrinta kanye nezindleko zezinto zokwakha kufanele kucatshangelwe.
Khetha izinto ezifanele ezisekelwe ezicini zomkhiqizo: isibonelo, ngokudla okudinga ukushiswa noma kufriziwe, singakhetha izinto ze-PP ezinokumelana okuhle kwezinga lokushisa; Ngemikhiqizo edinga ukucaca okuphezulu namandla, singakhetha impahla ye-PET.
Cabangela ukufaneleka kokuphrinta: Izinto ezihlukile zinezidingo ezihlukile zokunamathela kukayinki nokoma. Lapho sikhetha ama-substrates okuphrinta, sidinga ukucabangela ukufaneleka kokuphrinta kwezinto ukuze kuqinisekiswe umphumela wobuhle nokuhlala isikhathi eside wokuphrinta.
Ukulawulwa kwezindleko: Ngenkathi sihlangabezana nezici zomkhiqizo nokufaneleka kokuphrinta, sidinga futhi ukulawula izindleko ngendlela esingakhona ngayo. Isibonelo, uma kutholakala, singabeka kuqala izinto ze-PE ngezindleko eziphansi.
Kafushane, ekwakhiweni kwesakhiwo sokupakisha sokudlaamafilimu okupakisha epulasitiki, akudingekile ukuba nokuqonda okuphelele kwama-substrates angaphansi, kodwa ukuqonda okuyisisekelo nakho kuyadingeka. Kungale ndlela kuphela lapho singaqinisekisa ukuphepha kanye nokusha kokudla ngenkathi siklama ukupakishwa okuhle nokusebenzayo.
