Muchina wekunyungudutsa unonziwo wetting and dispersing agent. Kune rumwe rutivi, une wetting effect, kune rumwe rutivi, rumwe rutivi rweboka rayo rinoshanda runogona kunamirwa pamusoro pepigment yakapwanywa kuita zvidimbu zvidiki, uye rumwe rutivi runonyungudutswa kuita base material kuti rugadzire adsorption layer (mapoka akawanda ekunyungudutsa, chain link yakareba, adsorption layer yakakora) kuti ibudise charge repulsion (pendi inobva mumvura) kana entropy repulsion (pendi inobva mu solvent), kuitira kuti zvidimbu zvepigment zvigone kupararira uye kusungirirwa mupendi kwenguva yakareba kudzivirira flocculation zvakare. Izvi zvinoita kuti pave nekugadzikana kwekuchengetedza kwependi.
 
Mhando dzema dispersants anoshandiswa zvakanyanya.
1. Anionic wetting uye kuparadzira mumiriri
Mazhinji acho anoumbwa ne non-polar, negative charge hydrocarbon chain uye polar hydrophilic group. Mapoka maviri aya ari kumagumo maviri emorekuru, achiumba chimiro che asymmetric hydrophilic uye oleophilic molecular. Mhando dzayo ndeidzi: sodium oleate C17H33COONa, carboxylate, sulfate (RO-SO3Na), sulfonate (R-SO3Na), nezvimwewo. Kuenderana kwe anionic dispersants kwakanaka, uye polycarboxylic acid polymers, nezvimwewo zvinogona kushandiswawo kune solvent-based coatings uye zvinoshandiswa zvakanyanya se controlled flocculation-type dispersants.

2.Cationic wetting uye kuparadzira mumiriri
Aya macompounds asina simba repolar base ane positive charged, kunyanya amine salts, quaternary amine salts, pyridinium salts, nezvimwewo. MaCationic surfactants ane simba rakasimba re adsorption uye ane simba riri nani rekupararira pa carbon black, ma iron oxides akasiyana-siyana uye organic pigments, asi zvinofanira kucherechedzwa kuti anoita chemically ne carboxyl group iri mu base material, uye zvakare cherechedza kuti haafanirwe kushandiswa panguva imwe chete nema anionic dispersants.

3. Hutachiona hwefree radical hunodzora huwandu hwehyperdispersant
Chechipiri, basa remuparadziri
1. Kuvandudza kupenya uye kuwedzera mhedzisiro yekuyera.
2. Dzivisa ruvara rwunoyangarara uye kutumbuka.
3. Kuvandudza simba rekupenda.
4. Deredza viscosity uye wedzera pigment loading.
5. Deredza kuyerera kwemvura, wedzera kugona kuvaka uye kushandiswa kwayo.
6. Dzivisa kupenga uye kuwedzera kugadzikana kwekuchengetedza.
7. Wedzera kupararira kwemavara uye kuwanda kwemavara.
8. Wedzera kujeka kana simba rekufukidza.
9. Kuvandudza kushanda zvakanaka kwekugaya uye kuderedza mutengo wekugadzira.
10. Kudzivirira kugadzikana.
