KunyorovaDispersing agent MFyejasi haingokanganisa chete kujeka kwejasi, asi zvakare inokanganisa kuenzana kwepfuma yejasi. Kujeka kwejasi kunowanzotariswa nekupararira kwemwando kwejasi. Kujeka kwechifukidzo chimiro chekuvhara. Iyo yakakwirira kujeka, zviri nyore kuona iyo yepasi pasi. Iyo yakakwirira iyo inovhara simba, iyo yakasimba yepasi inovhara simba. Nekuda kwekuti pigment particles dzakasimba zvakanyanya pasi pechiito che wet dispersant dispersant, chivakwa chekuenzanisa chinowedzerwa, chinogona kuvandudza hunhu hwemvura yaNewton uye inobatsira pachiyero chekuyera.
WettingDispersing agent MFinovandudza kujeka nekukanganisa kugoverwa kwesaizi yepigment (yakawanda yunifomu uye yakamanikana). Kune titanium dioxide, yakakwira refractive index uye zvimedu zvakakura zvinogona kunyatso ratidza uye kufuratira mwenje weakasiyana wavelengths. Kuwedzera polymerDispersing agent MFinogona kuvandudza nzvimbo yepasi (kuderedza iyo polymer, kuderedza saizi yechikamu) uye kuwedzera kuvandudza kuvharika. Kune mavara akajeka, mapolymer dispersants anogona kuvandudza saizi yekugovera uye kubvumira mwenje wakawanda kupfuura (kuwedzera kujeka). Kuwanda kwechiedza chinoratidzwa uye chakapfuura nepamusoro pepamusoro chinotarisa kuvhara kana kujekesa kwekuputira. Rudzi rwepende uye kupararira kwayo zvese zvinoita mutsauko. Nekuda kwesimba rerefractive index uye size particle, kuvhara pigment kune simba guru pachiedza chinoratidzwa. Naizvozvo, tinogona kuvandudza kujeka nekuwedzera coating additives.
Kuenzana ndiko kugona kwejasi kupararira pane imwe nzvimbo. Coating surface defects inowanzokonzerwa nekukakavadzana kwepamusoro uye inoitika nokukurumidza. Mavara ebhurashi pamachira ekushongedza anowanzo kukonzerwa nekusakwana kuenzana. Yakanakira kuyera maitiro inogona kutsanangurwa neNewtonian mechanics. Asi mushure mekunge iyo pigment yaiswa muhurongwa, inoshanduka. Izvi zvinodaro nekuti zvimedu zvinokonzeresa thixotropy uye pseudoplasticity nekuda kwemakemikari zvisungo uye kusangana kwemuviri. Naizvozvo, isu tinogona kuvandudza chivakwa chekuenzanisa nekuwedzera coating additives.
Coating wetting dispersant yakakodzera kupfeka, pigment, color paste uye mamwe maindasitiri machira. Sechinhu chinowedzera, coating wetting dispersant ine simba guru pakuvandudza kujeka uye kupfava kwejasi. Huwandu hwekuputira wetting dispersant idiki, asi inodiwa mukugadzirwa kwekugadzira. Coating wetting dispersants inokanganisa kujeka uye kutsetseka kwejasi, saka zvakakosha zvikuru kuwedzera wetting dispersants kune yekupfeka.
