Ultrafine pigment phofo e arotsoe haholo ka li-pigment tsa organic le li-inorganic pigments, li-pigment tsa tlhaho li arotsoe haholo ka li-pigment tsa azo, li-pigment tsa letša, li-pigment tsa heterocyclic, li-pigment tse teteaneng tsa ring ketone, li-phthalocyanine pigments le tse ling. Inorganic pigments haholo-holo arotsoe ka titanium dioxide, k'habone e ntšo, tšepe oxide e khubelu, joalo-joalo Organic kapa inorganic pigments na le mebala e khanyang, matla a 'mala o phahameng, matla a' mala a phahameng le pepeneneng e phahameng, e finyellang litlhoko tsa lipehelo le li-inks tsa khatiso.
Leha ho le joalo, ka tshebetso ya ho lokisetsa pigment phofo, e khabane ea phatsa boholo, holim 'a pigment phofo tla eketseha, e leng ka habonolo lebisa agglomeration, ho etsa likaroloana khōlō, pente le tsamaiso enke hloka botsitso, ka ho teba ama boleng ba sehlahisoa.
Ka nako ena, manyolo ammonium letsoai dispersant ho hlokahala ho eketsa tshebetso pigment silakanya, pigment dispersant tsamaisong pigment peista, haholo-holo adsorb holim'a phofo, fokotsa holim'a matla a ultrafine pigment likaroloana, ho finyella junifomo dispersion phello, le manyolo ammonium letsoai dispersant ka ka katleho thibela flocculation khutlela mahoashe a bolulo phaphametseng mmala moriri. E lumellana hantle le pente le enke ea khatiso ho ntlafatsa ts'ebetso ea ho fana ka mebala.
HobanengMoemeli oa ho qhalakanya NNOsebetsa?
TheMoemeli oa ho qhalakanya NNOmolek'hule e na le sehlopha sa ankora le karolo e tsitsitseng. Mosebetsi oa sehlopha sa anchoring ke ho fana ka matla a lekaneng a tlamang ho likaroloana tsa pigment filler. Limolek'hule tse qhalakaneng ha li oele holim'a likaroloana, e leng ntho e hlokahalang hore li-disperant li sebetse. Mosebetsi oa karolo ea ho tsitsisa ke ho tsitsisa likaroloana tsa pigment aggregate tse qhalakantsoeng ke matla a mechine ka ho kheloha ha electrostatic le ho hanyetsa sebaka sebakeng sa mokelikeli ho thibela likaroloana ho kopanya.
Ka li-solvents tsa manyolo, ha karolo e tsitsitseng ea dispersant e tsitsisa likaroloana tsa pigment tse qhalakaneng ka ho hanyetsa sebaka, ha sebaka sa sebaka se arohaneng.Moemeli oa ho qhalakanya NNOlikaroloana li nyane ho feta boholo ba ketane ea solvent, ketane ea solvent e petetsana mme entropy e fokotseha. Ka metsing, ionization e etsahala ho pota-pota lihlopha tsa ionic ho theha lera habeli, 'me repulsion electrostatic thibela particle agglomeration. Haeba polyether e sa ionized e tsitsitse, polyether e tsitsisa likaroloana tsa pigment tse qhalakaneng ka ho hanyetsa sebaka.
