Sefahla-mokelikeli ke sesebelisoa se sebetsang sa interfacial se nang le litšobotsi tse peli tse fapaneng tsa lipophilicity le hydrophilicity ka har'a molek'hule.

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

Dispersants di ka hasanya ka ho lekana dikarolwana tse tiileng le tse metsi tsa di-pigment tse sa pheleng le tsa tlhaho tse thata ho qhibilihisa ka hara metsi, mme hape di thibela ho thella le ho koloba ha dikarolwana, ho etsa di-reagent tse amphiphilic tse hlokahalang bakeng sa ho emisoa ho tsitsitseng. Houhuan chemical R & D le tlhahiso ya di-additives tse thehilweng metsing le di-additives tse thehilweng oling diindastering tse fapaneng, dihlopha tse amanang le surfactant.

Sistimi ea ho hasana e arotsoe ka: tharollo, colloid le suspension (emulsion). Bakeng sa tharollo, solute ke disaspersant 'me solvent ke disaspersant. Mohlala, tharollong ea NaCl, disaspersant ke NaCl, 'me disaspersant ke metsi. Dispersant e bolela thepa e hasantsoeng ka likaroloana tsamaisong ea disaspersant. Ntho e 'ngoe e bitsoa ntho e hasantsoeng.

Mesebetsi ea ho sebelisa dispersant ea pigment ea indasteri ke e latelang:

1. Sebelisa sesebelisoa sa ho qhalakanya metsi ho fokotsa nako le matla a hlokahalang ho phethela ts'ebetso ea ho qhala, ho tsitsisa ho qhala ha pigment e qhalakantsoeng, ho khothaletsa ho khomarela ha PP, ho fetola litšobotsi tsa bokaholimo ba likaroloana tsa pigment, le ho lokisa ho tsamaea ha likaroloana tsa pigment.

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

3. Moqhalanyi ke sesebelisoa se thusang se ka ntlafatsang ho qhalana ha thepa e tiileng kapa e metsi.
