1. Asukume isikhwama sesikhwama se-doypackukuvuza
Ukuvuza kwesukuma isikhwama (doypack bag)ikakhulukazi kubangelwa ukukhethwa kwezinto eziyinhlanganisela namandla okufaka uphawu okushisa.
Okokuqala, ukukhethwa impahla yeasukume isikhwama sesikhwamakubaluleke kakhulu ukuvimbela ukuvuza.Inhloso ukuthuthukisa amandla okuxebuka phakathi kwesendlalelo sangaphandle kanye nesendlalelo sokuvimbela esiphakathi, phakathi kwesendlalelo sesithiyo kanye nesendlalelo sokuvala ukushisa kanye namandla okuvalwa kokushisa kwesikhwama.Ngakho-ke, ukungezwani okungaphezulu kwendawo eyinhlanganisela yefilimu kumele kube kukhulu kuno-38dyn/cm;Ukusebenza kokuvalwa kwezinga lokushisa okuphansi kwefilimu yokuvala ukushisa kwangaphakathi kungcono, futhi ukungezwani okungaphezulu kwendawo yokuvala ukushisa kufanele kube ngaphansi kuka-34 dyn/cm;Ngaphezu kwalokho, kuyadingeka ukukhetha ama-inks anokuxhumana okuhle, ama-adhesives anokuqukethwe okuphezulu okuqinile kanye ne-viscosity ephansi, nama-solvents e-organic anokuhlanzeka okuphezulu.
Okwesibili, amandla aphansi okuvala ukushisa nawo angenye yezinto ezibalulekile ezithinta ukuvuza kweasukume isikhwama sesikhwama.Ngesikhathi sokuvalwa kokushisa, ubudlelwano obuhambisanayo phakathi kwezinga lokushisa lokuvalwa kokushisa, ingcindezi yokuvala ukushisa kanye nesikhathi sokuvala ukushisa kuzolungiswa.Ikakhulukazi, kufanele sinake izinga lokushisa lokushisa kwezikhwama ezinezakhiwo ezahlukene.Ngenxa yokuthi amaphuzu ancibilikayo ezinhlobo ezahlukene zamafilimu epulasitiki ahlukile, izinga lokushisa lokuvalwa kokushisa nalo lihlukile;Ukucindezela kokuvalwa kokushisa akufanele kube phezulu kakhulu, futhi isikhathi sokuvala ukushisa akufanele sibe side kakhulu, ukuze ugweme ukuwohloka kwama-macromolecules.Isendlalelo sokuvala ukushisa sinqunywa ummese wokufaka uphawu lokushisa esimweni sokuncibilika kwezinga lokushisa eliphezulu, okuzonciphisa amandla okuvala.Ngaphezu kwalokho, uphawu ezine-ungqimba phansiasukume isikhwama doypack isikhwamaingxenye ebaluleke kakhulu.Izinga lokushisa lokuvalwa kokushisa, ingcindezi kanye nesikhathi kunganqunywa kuphela ngemuva kokuqinisekiswa okugcwele kokuhlolwa.Enqubweni yangempela yokukhiqiza, ukuhlolwa kokuvuza kuzokwenziwa kusikhwama sesikhwama sokumisa ngokuya ngezidingo ezahlukahlukene zokuqukethwe.Indlela elula futhi esebenzayo ukugcwalisa isikhwama ngenani elithile lomoya, ukushisa-ukuvalwa umlomo wesikhwama, ukuyibeka endishini equkethe amanzi, bese ucindezela izingxenye ezahlukene zesikhwama ngesandla sakho.Uma kungekho amagwebu aphunyukayo, kusho ukuthi isikhwama sivalwe kahle.Uma kungenjalo, izinga lokushisa elivala ukushisa nokucindezela kwengxenye evuzayo kuzolungiswa ngesikhathi.Asukume izikhwama doypack izikhwamaequkethe uketshezi kufanele iphathwe ngokuqapha okwengeziwe.Izindlela zokukhipha nokuwisa zingasetshenziswa ukuthola ukuthi kukhona ukuvuza koketshezi.Uma inani elithile lamanzi ligcwaliswa esikhwameni, umlomo kufanele uvalwe, futhi ukuhlolwa kufanele kwenziwe ngokwendlela yokuhlola ingcindezi ye-GB/T1005-1998.Indlela yokuhlola i-drop ingase futhi ibhekisele kumazinga angenhla.
2. Uhlobo lwesikhwama esingalingani
I-flatness ingenye yezinkomba zokulinganisa ikhwalithi yokubukekaizikhwama zokupakisha.Ngaphandle kwesici sezinto ezibonakalayo, ukugcwala kwesikhwama sokuzisekela nakho kuhlobene nokushisa kokuvalwa kokushisa, ukucindezelwa kokuvalwa kokushisa, isikhathi sokuvala ukushisa, umphumela wokupholisa nezinye izici.Uma izinga lokushisa lokuvalwa kokushisa liphezulu kakhulu, noma ingcindezi yokuvala ukushisa iphezulu kakhulu, noma isikhathi sokuvala ukushisa siside kakhulu, ifilimu ehlanganisiwe izoncipha futhi yonakale.Ukupholisa okunganele kuzoholela ekubunjweni okunganele ngemuva kokuvalwa kokushisa, okungakwazi ukuqeda ukucindezeleka kwangaphakathi nokushwabana isikhwama.Ngakho-ke, lungisa imingcele yenqubo futhi uqinisekise ukuthi uhlelo lokujikeleza kwamanzi okupholisa lusebenza ngokujwayelekile.
3. I-symmetry engalungile
I-Symmetry ayithinti kuphela ukubukeka kwe-asukume isikhwama sesikhwama, kodwa futhi kuthinta ukusebenza kwayo kokubeka uphawu.I-asymmetry ejwayelekile kakhulu ye-sukuma isikhwamangokuvamile kubonakala endabeni engezansi.Ngenxa yokulawula okungalungile kokungezwani kwezinto eziphansi, kuzodala ukuwohloka kwembobo engezansi noma imibimbi ngenxa yokungahambisani nokushuba kwezinto eziyinhloko, kunciphise amandla okuvalwa kokushisa.Lapho imbobo eyindingilizi engaphansi ikhubazekile, ukushuba kokukhishwa kuzoncishiswa ngokufanelekile, futhi isikhathi sokulinda sizokwengezwa ngesikhathi sokuvalwa kokushisa ukuze kulungiswe, ukuze kushiswe ngokugcwele ukuphambana kwezingqimba ezine ezansi kwesikhwama.Ngaphezu kwalokho, i-asymmetry yesikhwama nayo ihlobene nokulandela umkhondo kagesi, ukuphakela, idizayini yesikhombisi, ibhalansi ye-rubber roller, ukuvumelanisa kwe-steping motor noma i-servo motor nezinye izici.
