I-Dispersant i-ejenti esebenzayo ehlangene ebusweni enezici ezimbili eziphambene ze-lipophilicity kanye ne-hydrophilicity ngaphakathi kwe-molecule.

I-Dispersion isho ingxube eyakhiwe ngokuhlakazeka kwento eyodwa (noma izinto ezimbalwa) zibe kwenye into ngendlela yezinhlayiya.

Ama-dispersants angakwazi ukuhlakaza ngokulinganayo izinhlayiya eziqinile neziwuketshezi zemibala ye-inorganic kanye ne-organic okunzima ukukuncibilikisa oketshezini, futhi kuvimbele ukuthungwa nokufiphala kwezinhlayiya, zenze ama-amphiphilic reagents adingekayo ukuze kumiswe ukumiswa okuzinzile.I-Houhuan chemical R & D kanye nokukhiqizwa kwezithasiselo ezisekelwe emanzini nezithasiselo ezisekelwe kuwoyela ezimbonini ezihlukahlukene, izigaba ze-surfactant ezihlobene.

Uhlelo lokusabalalisa luhlukaniswe: isixazululo, i-colloid ne-suspension (emulsion).Ukuze uthole isixazululo, i-solute iyi-disperant futhi i-solvent iyi-disperant.Isibonelo, kusixazululo se-NaCl, i-disperant yi-NaCl, futhi i-disperant ngamanzi.I-disperant ibhekisela ezintweni ezihlakazekile zibe yizinhlayiya ohlelweni lokuhlakazeka.Enye into ibizwa ngokuthi i-dispersed substance.

Imisebenzi yokusebenzisa i-industrial pigment dispersant imi kanje:

1. Sebenzisa i-dispersant yokumanzisa ukuze unciphise isikhathi namandla adingekayo ukuze uqedele inqubo yokusabalalisa, uzinzise ukuhlakazeka kwe-pigment ehlakazekile, umgqugquzeli we-PP wokunamathela, uguqule izakhiwo ezingaphezulu zezinhlayiya ze-pigment, futhi ulungise ukuhamba kwezinhlayiya ze-pigment.

2. Yehlisa ukungezwani phakathi kobuso phakathi koketshezi oluwuketshezi kanye noketshezi oluqinile.Ama-disperants nawo angama-surfactants.Ama-disperants yi-anionic, i-cationic, i-non-ionic, i-amphoteric ne-polymeric.Phakathi kwabo, uhlobo lwe-anionic lusetshenziswa kakhulu.

3. Ihlakaza i-ejenti eyisizayo engathuthukisa ukuhlakazeka kwezinto eziqinile noma eziwuketshezi.
