Dispersant ke ntho e sebetsang ka har'a sefahleho e nang le litšobotsi tse peli tse fapaneng tsa lipophilicity le hydrophilicity ka har'a molek'hule.

Ho hasana ho bolela motsoako o entsoeng ke ho hasana ha ntho e le 'ngoe (kapa lintho tse' maloa) ho ea ho ntho e 'ngoe ka mokhoa oa likaroloana.

Dispersants ka ka mokhoa o tšoanang qhala e tiileng le mokelikeli likaroloana tsa inorganic le manyolo pigments hore ho le thata ho qhala ka metsi, 'me hape thibela sedimentation le condensation ea likaroloana, ho etsa amphiphilic reagents hlokahalang bakeng sa suspensions tsitsitseng.Houhuan lik'hemik'hale R & D le tlhahiso ea li-additives tse thehiloeng metsing le li-additives tse thehiloeng ka oli liindastering tse sa tšoaneng, lihlopha tse amanang le surfactant.

Tsamaiso ea ho hasana e arotsoe ka: tharollo, colloid le suspension (emulsion).Bakeng sa tharollo, solute ke dispersant 'me solvent ke dispersant.Ka mohlala, ka tharollo ea NaCl, dispersant ke NaCl, 'me dispersant ke metsi.The dispersant e bua ka thepa e qhalakantsoeng ka likaroloana tsamaisong ea ho hasana.Ntho e 'ngoe e bitsoa ntho e qhalakantsoeng.

Mesebetsi ea ho sebelisa li-indasteri tsa pigment dispersant ke tse latelang:

1. Sebelisa dispersant ea ho kolobisa ho fokotsa nako le matla a hlokahalang ho phethela ts'ebetso ea ho qhalakanngoa, ho tsitsisa ho qhalakanngoa ha pigment e qhalakaneng, PP adhesion promoter, ho fetola thepa ea holim'a likaroloana tsa pigment, le ho fetola ho tsamaea ha likaroloana tsa pigment.

2. Fokotsa tsitsipano ea sefahleho pakeng tsa mokelikeli-mokelikeli le o tiileng-mokelikeli.Li-dispersants le tsona ke li-surfactants.Li-disperants ke anionic, cationic, non-ionic, amphoteric le polymeric.Har'a bona, mofuta oa anionic o sebelisoa haholo.

3. Hlakola moemeli ea thusang ea ka ntlafatsang ho senyeha ha thepa e tiileng kapa ea metsi.
