I-Dispersant yi-ejenti esebenzayo ye-interfacial enezici ezimbili eziphikisanayo ze-lipophility kanye ne-hydrophicility ngaphakathi kwe-molecule.

Ukuhlakazeka kubhekiswa kwingxube eyakhiwe ngokuhlakazwa kwento eyodwa (noma izinto eziningana) kwenye into ngohlobo lwezinhlayiya.

Abasakazi be-dispersants bangasabalalisa ngokufana nezinhlayiya eziqinile neziwuketshezi zezithombe ze-inorganic nezocansi ezinzima ukuzikhipha ku-ketshezi, futhi futhi zivikele ukunqunyelwa kanye nokuvuselelwa kwezinhlayiya, kwakha ama-ampphipilic ama-reagents adingekayo ekumisweni okuzinzile. I-Houhuan Chemical R & D kanye nokukhiqizwa kwezithasiselo ezisuselwa emanzini kanye nezithasiselo ezenzelwe uwoyela ezimbonini ezahlukahlukene, izigaba ezihlobene nokuvimbela.

Uhlelo lokuhlakazeka luhlukaniswe: Isixazululo, i-colloid kanye nokumiswa (emulsion). Ukuze uthole isisombululo, uSoute ungumhlakaphi futhi u-solvent uhlakazekile. Isibonelo, kwikhambi le-NACL, abahlabelelayo yi-NACL, futhi abahlakazwa bangamanzi. Abahlakazekile basho izinto ezihlakazekile ngezinhlayiya ezinhlelweni zokuhlakazeka. Enye into ibizwa ngokuthi yinto ehlakazekile.

Imisebenzi yokusebenzisa izimboni zezinhlamvu zezinhlamvu zezimboni yimi ngalendlela elandelayo:

1. Sebenzisa ukuhlakazwa okumanzi ukunciphisa isikhathi namandla adingekayo ukuqedela inqubo yokuhlakazeka, qinisa i-Pigment Pipment Dissaverity, shintsha izimbangi zezinhlayiya ze-PP, shintsha ukuhamba kwezinhlayiya ze-pigment.

2. Yehlisa ukungezwani phakathi kokushintshana phakathi koketshezi oluwuketshezi noketshezi oluqinile. Abasakazi nabo nabo bangama-surfactants. I-dispersants iyi-anionic, i-cationic, i-non-ionic, i-amphoteric ne-polymeric. Phakathi kwazo, uhlobo lwe-anionic lusetshenziswa kakhulu.

I-3. I-Desssant i-ejenti elisizayo engathuthukisa ukuhluka kwezinto eziqinile noma zoketshezi.
