I-Dispersant iyi-ejenti esebenzayo ye-interfacial enezakhiwo ezimbili eziphikisanayo ze-lipophilicity kanye ne-hydrophilicity ngaphakathi kwe-molecule.

Ukuhlakazeka kubhekisela engxubeni eyakhiwe ukuhlakazeka kwento eyodwa (noma izinto eziningana) iye kwenye into ngesimo sezinhlayiya.

Ama-dispersants angahlakaza ngokulinganayo izinhlayiya eziqinile neziwuketshezi zama-pigment angaphili kanye nawangokwemvelo okunzima ukuwancibilikisa koketshezi, futhi avimbele ukubola kanye nokujiya kwezinhlayiya, akhe ama-reagent amphiphilic adingekayo ekumisweni okuzinzile. I-Houhuan chemical R & D kanye nokukhiqizwa kwezithasiselo ezisekelwe emanzini kanye nezithasiselo ezisekelwe kumafutha ezimbonini ezahlukahlukene, izigaba ze-surfactant ezihlobene.

Uhlelo lokusabalalisa luhlukaniswe phakathi: isixazululo, i-colloid kanye ne-suspension (emulsion). Ngesixazululo, i-solute iyi-dispersant kanti i-solvent iyi-dispersant. Isibonelo, kusisombululo se-NaCl, i-dispersant yi-NaCl, kanti i-dispersant ngamanzi. I-dispersant ibhekisela ezintweni ezihlakazekile zaba yizinhlayiya ohlelweni lokusabalalisa. Enye into ibizwa ngokuthi i-dispersed substance.

Imisebenzi yokusebenzisa i-industrial pigment dispersant yilena elandelayo:

1. Sebenzisa i-wetting dispersant ukunciphisa isikhathi namandla adingekayo ukuze kuqedwe inqubo yokuhlakazeka, kuqiniswe ukuhlakazeka kombala ohlakazekile, kukhuthazwe ukunamathela kwe-PP, kuguqulwe izakhiwo ezingaphezulu kwezinhlayiya zombala, futhi kulungiswe ukuhamba kwezinhlayiya zombala.

2. Nciphisa ukungezwani phakathi koketshezi oluyi-liquid kanye noketshezi oluqinile. Ama-Dispersants nawo angama-surfactants. Ama-Dispersants angama-anionic, ama-cationic, ama-non-ionic, ama-amphoteric kanye nama-polymeric. Phakathi kwawo, uhlobo lwe-anionic lusetshenziswa kakhulu.

3. Ukusatshalaliswa kwento engasiza engathuthukisa ukusatshalaliswa kwezinto eziqinile noma eziwuketshezi.
