Ngenxa yezindawo ezihlukene zokukhiqiza kanye nezinqubo zokukhiqiza, izinkinga ezahlukene zivame ukwenzeka ku-isikhwama sokupakishainqubo yokuhlanganisa.Izinkinga ezilandelayo kulula ukuzitshwa.
ibhamuza
Indawo emhlophe yenhlanganisela yefilimu eyenziwe nge-aluminium akufanele ifakwe ku-bubble phenomenon.Okokuqala, ama-bubbles ahlukaniswe abe yilawo aphuma emshinini kanye nalawo avela ngemva kokungena ekamelweni lokuphulukisa.Ngokuvamile, imikhiqizo eminingi ephuma emshinini ihlobene nesimo sokugqoka esimpofu, esihlobene nezinkinga ezifanayo ze-viscosity, ukugxila kanye ne-anilox roller.Ngokuvamile, ama-bubbles mancane futhi aminyene, futhi amakhosi anolwazi angabona ukuthi yimaphi ama-bubbles aphuma emshinini azonyamalala ngemva kokuphulukiswa, futhi angeke.Kodwa-ke, i-anti-stick phenomenon eyenzeka ngemva kokungena ekamelweni lokuphulukisa ihlobene kakhulu nokuhlanzeka okuphansi kwe-solvent.Lawa mabhamuza ngokuvamile awabonakali lapho ephuma emshinini, futhi azoshintshashintsha ngosayizi ngemva kokwelashwa, kusukela kubhontshisi wemung kuya kusayizi kabhontshisi wesoya.
ikhoneni lokugoqa
Izikhwama ezenziwe ngezinye izikhathi azilingani, ezinye izikhwama ziyisicaba ngakolunye uhlangothi kanti ezinye azisicaba, kanti ezinye ziyisicaba kulelikhona hhayi kulelo gumbi.Ngaphezu kokulawula ukungezwani, okuyisizathu sokuguqulwa kwefilimu, futhi izinga lokushisa lokushisa liphezulu kakhulu, kukhona nokushisa okungalingani kwefilimu ngesikhathi sokwelashwa, futhi lokhu kushisa okungalingani akukona ukungalingani ngaphakathi nangaphandle. yomqulu wefilimu, kodwa ibhekisela efilimini Zombili iziphetho zomqulu zishisiswe ngokulinganayo.Ukuqaphela ngokucophelela kuzothola ukuthi lapho isikhwama sigoqiwe, uhlangothi oluseduze ngokuvamile alugoqeki noma lungcono kakhulu, kanti olunye olukude olukude lona lusonteka kakhulu.Uma lokhu kuyisizathu, isipiliyoni somkhiqizi ukusishiya ekamelweni lokushisa isikhathi esithile ngemva kokuphuma ekamelweni lokuphulukisa, ukuze izinga lokushisa lomqulu wefilimu libuyiselwe ekufaneni.Yiqiniso, kungcono ukuvumela umqulu wefilimu ushiswe ngokulinganayo ngangokunokwenzeka ekamelweni lokuphulukisa, ngakho-ke qaphela indawo yokupaka kanye nendlela yomqulu wefilimu ekamelweni lokuphulukisa.
i-ejenti yokushelela
Amandla ekhasi aphansi ngenxa yokuna kwe-ejenti yokushelela, evame ukwenzeka kumafilimu e-PE anogqinsi oluyi-8C noma ngaphezulu.Ngemva kokuyidabula, uzothola ungqimba lwesithwathwa esimhlophe esinenkungu kulwelwesi lwangaphakathi, olungaphawulwa ngesandla.Dabula ucezu bese ulufaka kuhhavini oshisayo oshisayo imizuzu embalwa bese uyikhipha, amandla e-peel azokwanda kakhulu, kodwa ngemva kwemizuzu embalwa amandla e-peel azokwehla futhi.Uma kuyikhoyili eyinhlanganisela, ingaphinde ifakwe endlini yokwelapha futhi ibekwe endaweni eshisa ngaphezu kwamadigri angu-60 amahora angaphezu kuka-12, okungase kunxeshezelwe.Abanye abayitholanga indlela enhle.
okunamathelayo
Okusho ukuthi, ukwelapha akuphelele.Iningi lazo lihlobene nokuhlanzeka okuphansi kwe-solvent kanye nomswakama owedlulele wemvelo.Kuphinde kubangelwa ukuhlukanisa umgqomo weglue zibe amalungiselelo amabili, okwenza inani elingeziwe le-ejenti yokwelapha lingalungile.Ngokuvamile, lapho inani leglue elikhishwayo lilikhulu ngesikhathi esisodwa, izinga lomkhiqizo oyinhlanganisela lizinza kakhulu.Ngaphezu komkhuba wokulwa nokunamathela, okulula ukubangela izinkinga kuwoisikhwamaokwenza, kuphinde kube nenkinga ecashile eyethusa kakhulu.Okusho ukuthi, akunankinga ngokubeka isikhwama esiphelile efektri noma endaweni yekhasimende.Uma okuqukethwe sekulayishiwe (imvamisa ngaphezu kwezinsuku ezi-5), ubuso besikhwama buzovela bushwabene.Ngakho-ke uma uthola ukuthi ukwelapha akuphelele, ungathathi amashansi nekhasimende kalula.Okungenani kufanele ubeke okuqukethwe okufanayo nekhasimende embonini yakho ukuze kuhlolwe futhi kubhekwe, bese uletha izimpahla ngaphandle kwenkinga.
Ukungavuleki kahle ngemva kokwenziwa kwezikhwama
Ukuvulwa kweisikhwamaakukuhle.Ngaphandle kwezizathu zefilimu yangaphakathi ngokwayo kanye nokuguga okubangelwa ukuvulwa okubi, kunesinye isimo esilula ukwenzeka kwifilimu yangaphakathi encane (ngokuvamile mayelana ne-3c).Ngenxa yesenzo sesibophezelo esiyinhlanganisela, izithasiselo zefilimu zithuthela kusendlalelo esiyinhlanganisela sisonke, okuholela ekwenyukeni kwe-coefficient yokungqubuzana nokungavuleki kahle.
