I-Dispersant luhlobo lwe-agent esebenzayo edibeneyo, eneempawu ze-lipophilic kunye ne-hydrophilic kwiimolekyuli. Iyakwazi ukusasaza amasuntswana aqinileyo kunye nolwelo lwe-inorganic kunye ne-organic pigments ekunzima ukunyibilika kulwelo, ukuthintela i-particle sedimentation kunye ne-condensation, kwaye yenze iindidi ezimbini ze-philophile reagents ezifunekayo ukunqunyanyiswa okuzinzileyo.Iarhente yokusasaza iMF

I-surfactant yinto enokunciphisa ngokuphawulekayo ukuxinana komphezulu wesisombululo ekujoliswe kuso. Ineqela le-oyile ye-hydrophilic esisigxina enokuthi ijoliswe kumphezulu wesisombululo. Isakhiwo se-molecular of surfactants sineempawu ezimbini: enye isiphelo liqela le-hydrophilic, elinye iqela le-hydrophobic; Amaqela e-Hydrophilic ngokuqhelekileyo ngamaqela e-polar, afana ne-sulfonic acid, i-carboxylic acid, i-sulfuric acid, amaqela e-amino okanye i-amine kunye neetyuwa zabo, amaqela e-amide, amaqela e-hydroxyl, iibhondi ze-ether, njl., zingasetyenziswa njengamaqela e-polar hydrophilic; Amaqela e-Hydrophobic adla ngokuba ngamatsheyini e-nonpolar hydrocarbon, afana nalawo aneathom zekhabhoni ezingaphezulu kwesi-8. Ii-surfactants zohlulwe zibe zii-ionic surfactants (kubandakanya i-cationic surfactants kunye ne-anionic surfactants), ii-surfactants ezihlanganisiweyo, ii-amphoteric surfactants, ii-non-ionic surfactants, nezinye ii-surfactants njalo njalo.

Hayi indlela abasebenza ngayo abasasazi!

Iarhente yokusasaza iMFukholelwa ukuba wonke umntu akaqhelanga, siye sathetha kakhulu malunga phambi kweIarhente yokusasaza iMFulwazi, ngoko yintoni umgaqo wokusebenza we-dispersant? Ukuba awukaqhelani nolu lwazi, sinokufunda malunga nomgaqo wokusebenza we-dispersants kunye!

Umgaqo wokusasaza:

I-1, ifunxa phezu kobuso beengqungquthela eziqinileyo, ukunciphisa ukunyanzeliswa komhlaba phakathi kolwelo - ulwelo okanye ulwelo oluqinileyo. Umphezulu we-condensed particles eqinile kulula ukumanzisa.

I-2, i-polymer material uhlobo lwe-dispersant, kumphezulu weengqungquthela eziqinileyo zivelisa umaleko we-adsorption, ukwenzela ukuba intlawulo yomphezulu wamasuntswana aqinileyo yanda, iphucule amandla okubuyisela phakathi kweengqungquthela zokuthintela ezintathu-dimensional.

I-3, yenza umphezulu wamasuntswana aqinileyo avelise ubume besakhiwo semolekyuli ephindwe kabini, i-surface dispersant elungileyo kunye neegqithiso ezingalunganga zinobudlelwane obuqinileyo namanzi, ukuphucula inqanaba lamasuntswana aqinileyo amanzi ngamanzi. Umbindi wamasuntswana aqinileyo uyaphetshwa ngokunyanyiswa kwe-electrostatic inductive.

4, ukwenza inkqubo yolawulo symmetrical, iimpawu ezidadayo, akukho deposition, ukuze yonke inkqubo yolawulo iimpawu imichiza eziphilayo. Ngaphezulu, ukusetyenziswa kwe-dispersant kunokusasaza ngokuzinzileyo amasuntswana aqinileyo kwimeko yolwelo.
