Udindo waWobalalitsa MFndi kuchepetsa nthawi ndi mphamvu zofunika kuti amalize kubalalitsidwa ndondomeko, bata obalalika pigment kubalalitsidwa, kusintha pamwamba zimatha pigment particles, kusintha kayendedwe ka pigment particles, etc.
Zimaphatikizidwa muzinthu zotsatirazi:
Kufupikitsa nthawi ndi mphamvu yaWobalalitsa MFndondomeko
Kupyolera mu chiyanjano, pamwamba pa pigment particles akhoza kusinthidwa mofulumira kuchokera ku "mawonekedwe olimba a gasi" kukhala "mawonekedwe amadzi-olimba". Motero kuchepetsa nthawi ndi mphamvu zofunika pogaya.
Kuchepetsa mamasukidwe akayendedwe
Kugwiritsa ntchito dispersant kungachepetse mamasukidwe akayendedwe ndi kuonjezera Mumakonda mphamvu ya pigment.
Pewani flocculation ndi kubwerera ku coarse
Dispersant pa pigment pamwamba, kudzera electrostatic repulsion kapena wosabala cholepheretsa kupewa kukopana ndi kutseka, kuti kuonjezera bata la dongosolo.
Ndikoyenera kutchula kuti tinthu tating'onoting'ono ta pigment, kukulirapo kwa malo enieni, kukwezeka kwamphamvu padziko lapansi, kufunikira kwamphamvu kwamphamvu ya adsorption.Wobalalitsa MF, kotero kuchuluka kwa dispersant kumakhudzananso ndi ubwino wa phala.
Pewani tsitsi loyandama
Mofanana ndi mfundo yomwe ili pamwambayi, ndiye kuti kukhazikika kwa dispersant.
Sinthani magwiridwe antchito amtundu
Limbikitsani mphamvu zolembera, onjezerani mawonekedwe amtundu. Limbikitsani machulukitsidwe ndi kuwonekera kwa ma organic pigments, ndikuwonjezera mphamvu yobisala ya inorganic pigments.
Chikoka pakuchita filimu ya utoto
Dispersant sichidzasiya filimu ya utoto pambuyo popanga filimuyo, koma monga gawo lokhazikika la filimu ya utoto ilipo mu filimu ya utoto, ilibe mphamvu yaying'ono pakuchita filimu ya utoto.
Chikoka pa kukana madzi:
Kuchokera ku mfundo ya dispersant, akamanena za dispersant ndi surfactant, ndi amphiphilic katundu. Choncho, dispersant adzakhala ndi hydrophilic ndithu, mu utoto filimu zimakhudza kwambiri kukana madzi.
Sv-246h madzi ofotokoza superdispersant ndi hydrophobic kusinthidwa mankhwala, filimu youma, sizidzakhudza filimu yokha madzi kukana.
Zotsatira pa gloss:
Kunyezimira kwa utoto filimu pamwamba makamaka zimachokera kunyezimiritsa kuwala pa utoto filimu pamwamba, ndi dziko dziko zimadalira tinthu kukula kwa chigawo chilichonse, komanso ngakhale ndi kugawa boma.
Disperant kubalalitsidwa, kukhazikika mosakayikira kumathandiza kwambiri kuti gloss wa utoto filimu. Koma tiyenera kuganizira dispersant palokha ndi utomoni lokha ngakhale. Mwachitsanzo, SV-246H yochokera m'madzi ya superdispersant imakhala yogwirizana kwambiri ndi makina a acrylic opangidwa ndi madzi, ndipo imatha kukulitsa gloss ndi 2-3% poyerekeza ndi dispersants wamba monga 755W ndi 190.
mapeto
Dispersant ndi chowonjezera chofunikira kwambiri pakupaka.
Sizosiyana kokha ndi mafilimu omwe amapanga othandizira, pH regulator idzasokoneza mu kuyanika; Ndiwosiyananso ndi chonyowetsa, defoaming agent ndi thickening agent.
Chifukwa nthawi zonse imakhalapo mufilimu ya utoto ndipo imakhala ndi zinthu zambiri, imakhala ndi chikoka chachikulu pakuchita filimu ya utoto. Choncho, kusankha ndi kugwiritsa ntchito dispersant kumathandiza kwambiri pakuchita zokutira.
