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 ze-pigment ye-inorganic kanye ne-organic okunzima ukuyincibilikisa oketshezini, futhi iphinde ivimbele ukubola kanye nokufingqa 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 kanye nokumiswa (emulsion). Ukuze uthole isisombululo, 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 ukunciphisa isikhathi namandla adingekayo ukuze uqedele inqubo yokusabalalisa, uzinzise ukuhlakazeka kwe-pigment ehlakazekile, umgqugquzeli wokunamathela we-PP, 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. Izisabalalisi ziyi-anionic, i-cationic, i-non-ionic, i-amphoteric ne-polymeric. Phakathi kwabo, uhlobo lwe-anionic lusetshenziswa kakhulu.

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