Li-disperants ha lia ka tsa hlaha ho fihlela pente ea resin ea acrylic le pente ea resin ea polyester. Sena se boetse se amana haufi-ufi le nts'etsopele ea li-pigments, hobane ho sebelisoa ha li-pigment tse phahameng ho ke ke ha aroloa ho thuso ea li-dispersants.
Li-disperants ke li-additives tse sebelisoang ho tsitsisa likaroloana tse tiileng mecheng ea litaba tse kang likhomaretsi, lipente, lipolasetiki le metsoako ea polasetiki. Qetello e 'ngoe ea eona ke ketane ea tharollo e ka qhibilihang mecheng e fapaneng ea phatlalatso,' me pheletsong e 'ngoe ke sehlopha sa pigment anchoring se ka khabisoang holim'a li-pigments tse fapaneng' me se sebelisetsoa ho fetola sebopeho se tiileng / sa metsi (pigment / resin solution).

Tharollo ea resin e tlameha ho kenella lipakeng tsa li-pigment agglomerate. Li-pigments tsohle li teng e le li-pigment agglomerate, e leng "lipokello" tsa likaroloana tsa pigment, tse nang le moea le mongobo o nang le libaka tse ka hare pakeng tsa likaroloana tsa pigment ka bomong. Likaroloana li kopana ka mathōko le likhutlong, 'me litšebelisano pakeng tsa likaroloana li batla li le nyenyane, kahoo matla ana a ka hlōloa ke lisebelisoa tse tloaelehileng tsa ho hasana. Ka lehlakoreng le leng, li-aggregates li kopane haholoanyane, 'me ho na le kamano ea sefahleho le sefahleho pakeng tsa likaroloana tsa pigment ka bomong, kahoo ho thata haholo ho li qhalakanya likarolong tse ka sehloohong. Nakong ea ts'ebetso ea ho sila ea pigment, li-pigment agglomerate butle-butle li fetoha tse nyane; boemo bo loketseng ke ho fumana likaroloana tsa mantlha.

Mokhoa oa ho sila oa pigment o ka aroloa ka mehato e meraro e latelang: mohato oa pele ke ho kolobisa. Tlas'a ho sisinyeha, moea oohle le mongobo o holim'a pigment li ntšoa 'me li nkeloa sebaka ke tharollo ea resin. The dispersant e ntlafatsa ho koloba ha pigment, ho fetola sebopeho se tiileng / sa khase hore e be sebopeho se tiileng / sa metsi le ho ntlafatsa ts'ebetso ea ho sila; mohato oa bobeli ke mokhoa oa sebele oa ho sila oa pigment. Ka tšusumetso ea matla le matla a ho kuta, li-pigment agglomerate li robehile 'me boholo ba karoloana bo fokotsehile ho ba likaroloana tse ka sehloohong. Ha pigment e buloa ka matla a mochine, dispersant e tla potlakela ho adsorb le ho phuthela likaroloana tse nyenyane tsa boholo ba likaroloana; mohatong oa ho qetela oa boraro, phallo ea pigment e tlameha ho tsitsa ka ho lekaneng ho thibela ho thehoa ha flocculation e sa laoleheng.

Tšebeliso ea dispersant e loketseng e ka boloka likaroloana tsa pigment sebakeng se loketseng ho tloha ho tse ling ntle le ho tsosolosa kamano. Lits'ebetsong tse ngata, ho batloa boemo bo tsitsitseng ba deflocculated. Lits'ebetsong tse ling, phallo ea pigment e ka lula e tsitsitse tlas'a maemo a laoloang a coflocculation. Lithuso tsa ho kolobisa li ka fokotsa phapang ea tsitsipano lipakeng tsa pigment le tharollo ea resin, e potlakisa ho koloba ha li-pigment agglomerates ka resin; lithuso tsa ho qhalakanya li matlafatsa botsitso ba ho hasana ha pigment. Ka hona, sehlahisoa se tšoanang hangata se na le mesebetsi ea lithuso tsa ho kolobisa le ho qhalakanya.

Pigment dispersion ke ts'ebetso ho tloha ho kakaretso ho ea ho naha e qhalakaneng. Ha boholo ba likaroloana bo fokotseha 'me sebaka se ka holimo se ntse se eketseha, matla a holim'a tsamaiso a boetse a eketseha.
Kaha matla a holim'a tsamaiso ke ts'ebetso e fokotsehang ka boomo, ha ho ntse ho totobetse ho eketseha ha sebaka se ka holimo, ho hlokahala matla a mangata ho sebelisoa ho tsoa ka ntle nakong ea ts'ebetso ea ho sila, 'me matla a matla a ho tsitsisa a dispersant a hlokahala ho boloka botsitso ba ho hasana ha tsamaiso. Ka kakaretso, li-pigment tsa inorganic li na le boholo bo boholo ba likaroloana, libaka tse tlase tse ikhethileng, le polarity e phahameng ea holim'a metsi, kahoo ho bonolo ho hasanngoa le ho tsitsisa; ha mefuta e fapaneng ea li-pigment le carbon black e na le boholo bo fokolang ba likaroloana, libaka tse kholo tse khethehileng tsa holim'a metsi, le polarity e tlaase, kahoo ho thata ho li qhalakanya le ho li tsitsisa.

Ka hona, li-disperants haholo-holo li fana ka likarolo tse tharo tsa ts'ebetso: (1) ho ntlafatsa ho koloba ha pigment le ho ntlafatsa bokhoni ba ho sila; (2) ho fokotsa viscosity le ho ntlafatsa ho lumellana le thepa ea motheo, ho ntlafatsa khanya, botlalo le ho khetholla ha setšoantšo, le ho ntlafatsa botsitso ba polokelo; (3) ho eketsa matla a 'mala oa 'mala le mahloriso a mebala le ho ntlafatsa botsitso ba' mala.
