I-Dispersant yi-arhente esebenzayo edibeneyo eneempawu ezimbini ezichasene ne-lipophilicity kunye ne-hydrophilicity ngaphakathi kwe-molecule.

Ukusasazwa kubhekiselele kumxube owenziwe kukusasazeka kwento enye (okanye izinto ezininzi) ukuya kwenye imo yamasuntswana.

I-Dispersants inokusasaza ngokulinganayo amasuntswana aqinileyo kunye nolwelo lwe-pigments ye-inorganic kunye ne-organic enzima ukunyibilika kulwelo, kwaye ikwanqande intlenga kunye nokuxinana kwamasuntswana, ukwenza ii-amphiphilic reagents ezifunekayo ukunqunyanyiswa okuzinzileyo.I-Houhuan ikhemikhali ye-R & D kunye nemveliso yezongezo ezisekelwe emanzini kunye nezongezo ezisekelwe kwioli kumashishini ahlukeneyo, amacandelo anxulumene ne-surfactant.

Inkqubo yokusabalalisa ihlukaniswe: isisombululo, i-colloid kunye nokumiswa (emulsion).Kwisisombululo, isinyibilikisi sisisasazi kwaye isinyibilikisi sisisasazi.Ngokomzekelo, kwisisombululo se-NaCl, i-disperant yi-NaCl, kwaye i-disperant ngamanzi.I-disperant ibhekisela kwizinto ezichithwayo zibe ngamaqhekeza kwinkqubo yokusabalalisa.Enye into ibizwa ngokuba yi-dispersed substance.

Imisebenzi yokusebenzisa i-industrial pigment dispersant yile ilandelayo:

1. Sebenzisa i-wetting dispersant ukunciphisa ixesha kunye namandla afunekayo ukugqiba inkqubo yokusabalalisa, ukuzinzisa ukusabalalisa i-pigment dispersion, umgqugquzeli wePP adhesion, ukuguqula iipropati ze-pigment particles, kunye nokulungelelanisa ukuhamba kwe-pigment particles.

2. Nciphisa ukunyanzeliswa kobuso phakathi kolwelo-ulwelo kunye nolwelo oluqinileyo.Ii-dispersants nazo zi-surfactants.I-Disperpers i-anionic, i-cationic, i-non-ionic, i-amphoteric kunye ne-polymeric.Phakathi kwabo, uhlobo lwe-anionic lusetyenziswa kakhulu.

3. Ukusabalalisa i-agent encedisayo enokuphucula ukuchithwa kwezinto eziqinileyo okanye ezimanzi.
