UkumanzisaIarhente yokusasaza iMFyokwaleka ayichaphazeli nje kuphela elubala yokwaleka, kodwa kuchaphazela ipropathi yokulinganisa yokwambathisa. Ukungafihli kokwaleka ngokuqhelekileyo kugqitywe ngokusasazwa kokufuma kwengubo. Ukungafihli kokwaleka luphawu lokwaleka. Okukhona kubonakala elubala, kokukhona kulula ukubona umaleko ongezantsi. Okukhona uphezulu amandla okugquma, kokukhona anamandla okugquma asezantsi. Ngenxa yokuba iinqununu ze-pigment zizinzile phantsi kwesenzo se-dispersant emanzi, ipropati yokulinganisa iyanda, enokuphucula iimpawu ze-Newton fluid kwaye inenzuzo kwipropati yokulinganisa.
UkumanzisaIarhente yokusasaza iMFiphucula ukungafihli ngokuchaphazela ubungakanani besuntswana lokuhanjiswa kwee-pigments (iyunifomu ngakumbi kwaye incinci). Kwi-titanium dioxide, isalathisi esiphezulu se-refractive kunye neengqungquthela ezinkulu zinokubonakalisa ngokufanelekileyo kunye nokukhanya kwe-refract of wavelengths eyahlukeneyo. Ukongeza i-polymerIarhente yokusasaza iMFinokuphucula indawo engaphezulu (ukunciphisa i-polymer, ukunciphisa ubukhulu be-particle) kunye nokuphucula ngakumbi ukugubungela. Kwii-pigments ezicacileyo, i-polymer dispersants inokuphucula ukusabalalisa ubungakanani bamasuntswana kwaye ivumele ukukhanya okungakumbi ukuba kudlule (ukwandisa ukukhanya). Ubungakanani bokukhanya okubonakalisiweyo kunye nokugqithiswa kumphezulu kugqiba ukugubungela okanye ukungafihli kwengubo. Uhlobo lwepeyinti kunye nokusasazwa kwayo yonke into yenza umahluko. Ngenxa yempembelelo yesalathiso se-refractive kunye nobukhulu be-particle, i-pigment yokugubungela inempembelelo enkulu ekukhanyeni okubonakalayo. Ke ngoko, sinokuphucula ukungafihli ngokongeza izongezo zokwaleka.
Ukunyuswa komgangatho kukukwazi kwengubo yokusabalalisa phezu kwendawo ethile. Iziphene zokwambathisa zidla ngokubangelwa kukuxinana komphezulu kwaye zenzeke ngokukhawuleza. Iimpawu zebrashi kwiingubo zokuhombisa nazo zidla ngokubangelwa kukungalingani ngokwaneleyo. Ukuziphatha okufanelekileyo komgangatho kunokuchazwa ngabakhandi beNewtonian. Kodwa emva kokuba i-pigment ifakwe kwinkqubo, iyatshintsha. Oku kungenxa yokuba amasuntswana achaphazeleka kwi-thixotropy kunye ne-pseudoplasticity ngenxa yeebhondi zeekhemikhali kunye nokusebenzisana ngokomzimba. Ngoko ke, sinokuyiphucula ipropathi yokulinganisa ngokongeza izongezo zokwaleka.
I-Coating wetting dispersant ilungele ukugquma, i-pigment, i-color paste kunye nezinye iingubo zamashishini. Njengesongezo esiqhelekileyo, i-coating ye-wetting dispersant inempembelelo enkulu ekuphuculeni ukungafihli kunye nokukhanya kwengubo. Ubungakanani be-coating wetting dispersant buncinci, kodwa kuyimfuneko kwinkqubo yokuvelisa ukutyabeka. I-Coating wetting dispersants ichaphazela ukungafihli kunye nokuguda kwengubo, ngoko kubaluleke kakhulu ukongeza i-dispersants yokumanzisa kwi-coating.
