Ho kolobaMoemeli oa ho qhalakanya MFea barbotage ha e ame feela pepeneneng ea barbotage, empa hape e ama thepa leveling ea barbotage. Ho pepeseha ha ho roala ka kakaretso ho khethoa ke ho hasana ha mongobo oa ho roala. Ho pepeseha ha ho roala ke tšobotsi ea ho roala. Ha khanya e phahame, ho bonolo ho bona lera le ka tlaase. Ha matla a koahelang a phahame, matla a koahelang a tlase a matla. Hobane likaroloana tsa pigment li tsitsitse haholoanyane tlas'a ts'ebetso ea dispersant e nang le metsi, thepa e lekaneng ea eketseha, e ka ntlafatsang litšobotsi tsa mokelikeli oa Newton 'me e na le molemo ho thepa e leka-lekaneng.

Ho kolobisaMoemeli oa ho qhalakanya MFe ntlafatsa ponaletso ka ho ama kabo ea boholo ba phatsa ea li-pigments (unifomo e eketsehileng le e moqotetsane). Bakeng sa titanium dioxide, index e phahameng ea refractive le likaroloana tse kholo li ka bonahatsa le ho fetola khanya ea maqhubu a fapaneng. Ho eketsa polymerMoemeli oa ho qhalakanya MFe ka ntlafatsa sebaka se ka holimo (ho fokotsa polymer, ho fokotsa boholo ba likaroloana) le ho ntlafatsa ho koahela. Bakeng sa li-pigments tse pepeneneng, li-polymer dispersants li ka ntlafatsa kabo ea boholo ba likaroloana le ho lumella leseli le eketsehileng ho feta (ho eketsa pepeneneng). Bongata ba leseli le bonts'itsoeng le ho fetisoa ka holim'a metsi le etsa qeto ea ho koahela kapa ho pepeseha ha seaparo. Mofuta oa pente le ho hasana ha eona kaofela li etsa phapang. Ka lebaka la tšusumetso ea index ea refractive le boholo ba likaroloana, pigment e koahelang e na le phello e kholo ho khanya e bonts'itsoeng. Ka hona, re ka ntlafatsa ponaletso ka ho eketsa li-additives tsa ho roala.

 

Leveling ke bokhoni ba ho roala ho hasana holim'a sebaka se itseng. Litšitiso tsa ho roala holim'a metsi hangata li bakoa ke tsitsipano ea holim'a metsi 'me li etsahala ka potlako. Matšoao a borashe holim'a liaparo tse khabisitsoeng le tsona hangata li bakoa ke boemo bo sa lekaneng. Boitšoaro bo nepahetseng ba boemo bo ka hlalosoa ke mechanics ea Newtonian. Empa ka mor'a hore pigment e kenngoe tsamaisong, e fetoha. Lebaka ke hore likaroloana li ka hlaseloa ke thixotropy le pseudoplasticity ka lebaka la litlamo tsa lik'hemik'hale le likamano tsa 'mele. Ka hona, re ka ntlafatsa thepa ea ho leka-lekanya ka ho eketsa li-additives tsa ho roala.

 

Coating wetting dispersant e loketse ho roala, pigment, peista ea mebala le liaparo tse ling tsa indasteri. Joalo ka tlatsetso e tloaelehileng, coating wetting dispersant e na le tšusumetso e kholo ho ntlafatseng pepeneneng le ho batalla ha ho roala. Palo ea ho roala wetting dispersant e nyane, empa e hlokahala ts'ebetsong ea tlhahiso ea ho roala. Li-disperants tsa ho roala li-coating li ama ho pepeseha le ho boreleli ha seaparo, kahoo ke habohlokoa haholo ho eketsa li-dipersants tsa ho kolobisa ho roala.
