Izinga lezingubo, ezaziwa nangokuthi flatness noma ukufana, inkomba ebalulekile yokukala ukusebenza kokuhlobisa kwezingubo.I-National Standard GB1750-89(79) inikeza izindlela eziqondile zokunquma izinga.
Upende luyaxutshwa noma lufafazwe ku-base plate ngendawo eyisicaba ngokuya ngendlela evamile yokulungiselela ifilimu kapende.Ngenkathi ibhulashi livula ithempulethi, isitophuwashi siyavulwa ukukala isikhathi esidingekayo ukuze ibhulashi linyamalale futhi lenze indawo yefilimu ebushelelezi ngokuphelele, evezwe ngemizuzu.
Ukufafaza ngale ndlela engenhla, bheka indawo kapende ukuze uthole isikhathi sesimo esifanayo, esibushelelezi, esingenamibimbi.Enye indlela ukulungisa isampula kapende ku-viscosity yesicelo, uyifake kusampula nge-primer, uyenze ibushelelezi futhi ilingane, khona-ke phakathi nefilimu ngebhulashi longitudinal ibhulashi uphawu lwebhulashi, bheka ukuthi uphawu lwebhulashi lwesikhathi esingakanani luyanyamalala. , ifilimu ibuyiselwa endaweni ebushelelezi.
Ngokuvamile ngokusho kwefilimu ukuze ufinyelele indawo ebushelelezi yesilinganiso sesikhathi: hhayi imizuzu engaphezu kwe-10 enhle;Imizuzu eyi-10 kuye kweyi-15 iyafaneleka;ngemva kwemizuzu engu-15 akuyona iyunifomu ayifaneleki (enamathela non-zokuhlobisa ayikwazi ukwenza le mfuneko)
Ukuhlolwa kokusebenza kokulinganisa kunobudlelwano obuhle nezinhlobonhlobo kanye ne-viscosity yezingubo.Ukusebenza kokulinganisa kwezingubo ze-viscosity ephezulu ngokuvamile kuphansi kunaleyo ye-viscosity ephansi.Ngokuthuthuka kwesayensi nobuchwepheshe, eminyakeni yamuva, izinsiza eziningi ezintsha zokulinganisa ziye zasetshenziswa kancane kancane, njenge-Polyacrylic acid esters, yonke impahla ye-rheological kanye nempahla yokukala ye-coating ingathuthukiswa kakhulu.
Lapho amamaki webhulashi noma ikhasi lewolintshi linyamalala, i-coating surface icwebezela, okungukuthi, ukusebenza kokuhlobisa kungcono.Ukusebenza kokulinganisa kwezingubo kuhlobene nokwakheka kanye nenani le-resin, i-pigment ne-solvent, kanye nendlela yokufaka isicelo.
