Ukufinyelela kalula emakhoneni nasezikhaleni.Ngenxa yokusetshenziswa komfutho ophezulu kanye nokufuthwa okungenamoya, isifutho sikapende asinawo umoya, futhi opende bangafinyelela kalula emakhoneni, izikhala nezingxenye ezingalingani, ikakhulukazi ezakhiweni zamahhovisi ezinamapayipi amaningi okupholisa umoya namapayipi okulwa nomlilo.
Izembatho ze-viscosity eziphakeme zingafuthwa, kuyilapho ibhulashi lesandla kanye nokufuthwa komoya kusebenza kuphela ezingxenyeni eziphansi ze-viscosity.Ngokuthuthuka komnotho kanye nokushintsha komqondo wabantu, sekuyimfashini ukuhlobisa udonga ngezingubo zodonga zangaphakathi nezisezingeni eliphezulu zangaphakathi nezangaphandle esikhundleni sama-mosaic namathayili e-ceramic emhlabeni.
Upende we-emulsion osemanzini usuphenduke into ethandwa kakhulu yokuhlobisa odongeni lwangaphakathi nangaphandle ngenxa yokungenabuthi, ukuhlanza okulula, umbala ocebile futhi akukho ukungcoliswa kwemvelo.Kodwa upende we-emulsion uwuhlobo lopende olusekelwe emanzini olune-viscosity ephezulu.Ngesikhathi sokwakhiwa, abakhiqizi abajwayelekile banemikhawulo eqinile kakhulu ekuhlanjululweni kopende wangempela ngamanzi, ngokuvamile i-10% - 30% (ngaphandle kwefomula ekhethekile yokugqoka engakwazi ukwengeza amanzi amancane ngaphandle kokuthinta ukusebenza kokugqoka, okuzobhalwa. encwadini yomkhiqizo).
Ukuhlanjululwa ngokweqile kuzoholela ekwakhekeni kwefilimu okungekuhle, futhi ukuthungwa kwayo, ukumelana nokukhuhla nokuqina kuzolimala ngamazinga ahlukahlukene.Idigri yomonakalo ilingana ngokuqondile ne-dilution, okungukuthi, i-dilution enkulu, ikhwalithi yefilimu iba yimbi kakhulu.Uma izidingo ze-dilution zomenzi zilandelwa ngokuqinile, i-viscosity yepende ye-emulsion iphezulu kakhulu futhi ukwakhiwa kunzima.Uma i-roller coating, i-brush coating noma i-spraying yomoya isetshenziselwa ukwakhiwa, umphumela wepende unzima ukwanelisa.Emazweni angaphandle, indlela ethandwa kakhulu ukusebenzisa umshini wokufafaza ongenawo umoya onengcindezi ephezulu yokwakha.
Upende we-latex ngokuvamile awunawo ama-organic solvents.Ayinayo nje kuphela i-volatilization ye-solvent ngesikhathi sokukhiqiza nokwakhiwa, kodwa futhi ayinakho ukungcola endaweni ezungezile, futhi ukukhululwa kwe-organic volatiles ngesikhathi sokusetshenziswa kuphansi kakhulu.Isamba senani le-VOC (i-organic volatile matter) ngokuvamile lingaphakathi kwebanga elivumelekile lezinga.Kuyinto ephephile, ehlanzekile futhi enobungani bemvelo yokuhlobisa isakhiwo esiluhlaza okokuhlobisa.
Upende we-emulsion osuselwe emanzini unokungena komoya okuhle kanye nokumelana okuqinile kwe-alkali.Ngakho-ke, akulula ukuqhuma uma kukhona umehluko omkhulu phakathi komswakama wangaphakathi nangaphandle we-coating, futhi ukugqoka akulula "ukujuluka" endlini.Ifaneleka ngokukhethekile ukudweba endaweni ye-cement kanye ne-plaster surface yezindonga zangaphakathi nezangaphandle zezakhiwo.Upende we-Latex usetshenziselwa kabanzi ukuhlobisa udonga lwangaphakathi nangaphandle lwezakhiwo ngenxa yezinhlobonhlobo, umbala ogqamile, isisindo esilula kanye nomhlobiso wesakhiwo esisheshayo.
