Izizathu ezimbalwa ezinkulu zokuhlunga upende (一)

1.Ibhamuza: into eyenza amabhamuza akhe phezu kwezingxenye ezisindile ngenxa yokukhishwa kwegesi okunodlame.Ebizwa nangokuthi i-blister, iyisici sokumboza.Ngenxa yokungangeni kahle kwamanzi kanye nokumelana namanzi kwefilimu yokumboza kapende osuselwe ku-solvent, ngesikhathi sokuguga kwangaphandle, ngenxa yethonya lemvula noma indawo emanzi, kukhona ukugeleza kwamanzi ngaphansi kwefilimu yokumboza, futhi ngemva kokuhwamuka, ukungakwazi ukungena nokungena emanzini. ifilimu yokugqoka ethambile ngamanzi iyakhukhumala, yenze ama-bubbles.Umswakama ongaphezulu uphezulu, umswakamo we-ambient uphakeme, izinga lokushisa liphezulu kakhulu, i-putty ayivalwanga kahle, futhi isikhawu phakathi kwezingqimba azanele.

I-2.I-Pinhole: Ngemva kokuba ifilimu yokumboza isomile, ingaphezulu lesihlungi sikapende lizokwenza i-pinhole, efana nezimbotshana zesikhumba.Lesi sici sibizwa ngokuthi i-pinhole.Ngesikhathi sokwakhiwa kokufafaza, i-solvent kanye nomoya kuzohwamuka ngokushesha futhi kubaleke ifilimu yokugqoka emanzi, ezokwenza imbobo encane.Ngalesi sikhathi, ifilimu emanzi ayinalo uketshezi olwanele, olungakwazi ukulinganisa imbobo encane, ishiye imbobo emise okwenaliti.Uma kukhona umkhondo wamanzi kupende noma ku-solvent, ama-pinholes angenzeka kakhulu.I-diluent kufanele ikhethwe ngokuqinile ukuze kuvinjwe amanzi nezinye i-sundries ekuxubeni, futhi i-viscosity yokwakha kufanele ilawulwe ngesikhathi esifanayo ukuze kuncishiswe noma kugwenywe ukubukeka kwama-pinholes.Kodwa uma kuyinkinga ye-pinhole kapende osekelwe emanzini, kuyoba inkinga yefomula.
I-diluent yengezwa incane kakhulu, i-viscosity yesihlungi sikapende inkulu kakhulu, ukumbozwa kuminyene kakhulu, isikhawu phakathi kwezingqimba asanele, isikhathi esimile ngemva kokuhlanjululwa kopende asanele, futhi i-diluent ishintshashintsha kancane kakhulu.

I-3.I-Pelleting: indawo yokwakha yokufafaza isikrini sokuhlunga ayihlanzekile, i-workpiece iqukethe amafutha, amanzi nothuli, ukungcola okuxubene ne-coating akuhlungiwe, amathuluzi okudweba neziqukathi azihlanzekile, upende awuxubene ngokugcwele, futhi isikhathi sokuhlunga nesikhathi sokuma azanele.

I-4.Shrinkage hole: isikrini sokuhlunga isifutho sibizwa nangokuthi umgodi.Kubhekiselwa kusici semigodi emincane eyindilinga kwifilimu yokumboza.Ngemuva kokuthi kusetshenziswe ukumbozwa, ifilimu emanzi iyancipha ngesikhathi senqubo yokulinganisa, ishiya inqwaba yezimbobo zokunciphisa ezinobukhulu obuhlukene nokusabalalisa ngemva kokumisa.Lokhu kungenxa yomehluko wokungezwani kwendawo phakathi kwezingxenye ezingaphezulu nezingezansi zefilimu emanzi kanye nokungalinganisi kahle.Ingaxazululwa ngokungeza izinsiza ezifanele zokulinganisa noma izincibilikisi ezicindezela phezulu.
Isendlalelo esingezansi singcolile, i-workpiece iqukethe amafutha, amanzi nothuli, njll. Isendlalelo esingezansi sibushelelezi kakhulu, ukugaya akwanele, izinga lokushisa lokwakha liphansi kakhulu noma umswakama uphezulu kakhulu.

5.I-Underbite: Uma ufutha isikrini sokuhlunga ngejazi lesibili likapende, upende osanda kufakwa uluma ifilimu eyomisiwe ngaphambilini kusukela ku-substrate.Uma lokhu kwenzeka, ukunamathela kuzonwebeka, kugudluke, kushwabane, kushwabane, kuqhume, noma kulahlekelwe ukunamathela bese kuwa.I-primer kanye nejazi lokuqeda azifani;Ukuncibilika kwe-solvent kapende wokuqeda kuqine kakhulu;Uma i-primer ingasomile ngokuphelele, izodala "undercut".
I-primer kanye nopende wokuqeda akuhambisani, ikhefu phakathi kwezingqimba azanele, ungqimba olungezansi alomile, i-diluent inamandla kakhulu, futhi ukumboza kukhulu kakhulu ngesikhathi esisodwa.
