Dispersant ndi mtundu wa interfacial yogwira wothandizira, amene ali lipophilic ndi hydrophilic katundu mu mamolekyu. Iwo akhoza kumwazitsa olimba ndi madzi particles wa inorganic ndi organic inki kuti n'zovuta kupasuka mu madzi, kuteteza tinthu sedimentation ndi condensation, ndi kupanga mitundu iwiri ya philophile reagents zofunika kuyimitsidwa khola.Wobalalitsa MF

A surfactant ndi chinthu chomwe chingathe kuchepetsa kwambiri kugwedezeka kwa pamwamba pa njira yothetsera. Ili ndi gulu lokhazikika lamafuta a hydrophilic omwe amatha kuyang'ana pamwamba pa yankho. Mapangidwe a maselo a surfactants ali ndi zinthu ziwiri: mapeto amodzi ndi gulu la hydrophilic, mapeto ena ndi gulu la hydrophobic; Magulu a Hydrophilic nthawi zambiri amakhala magulu a polar, monga sulfonic acid, carboxylic acid, sulfuric acid, amino kapena amine magulu ndi mchere wawo, magulu a amide, magulu a hydroxyl, ether bonds, etc., angagwiritsidwenso ntchito ngati magulu a polar hydrophilic; Magulu a Hydrophobic nthawi zambiri amakhala maunyolo a hydrocarbon a nonpolar, monga omwe amakhala ndi maatomu a kaboni opitilira 8. Ma surfactants amagawidwa kukhala ma surfactants a ionic (kuphatikiza ma cationic surfactants ndi anionic surfactants), ma surfactants ophatikizika, ma amphoteric surfactants, ma surfactants omwe si a ionic, ma surfactants ena ndi zina zotero.

Obalalitsa amagwira ntchito bwanji!

Wobalalitsa MFamakhulupirira aliyense osati zachilendo, takambirana zambiri pamaso paWobalalitsa MFzambiri, ndiye mfundo yogwira ntchito ya dispersant ndi yotani? Ngati simunadziwebe chidziwitso ichi, titha kuphunzira za mfundo yogwirira ntchito ya dispersants pamodzi!

Dissperant mfundo:

1, kuyamwa pamwamba pa tinthu tating'onoting'ono, kuchepetsa kusamvana kwapakati pamadzi - madzi kapena olimba-zamadzimadzi. Pamwamba pa condensed olimba particles n'zosavuta kunyowa.

2, polima zakuthupi mtundu dispersant, pamwamba pa particles olimba kubala adsorption wosanjikiza, kuti mlandu padziko olimba particles kuwonjezeka, kusintha recoil mphamvu pakati pa particles atatu azithunzithunzi kutsekereza kutsekereza.

3, kupanga padziko olimba particles kubala iwiri maselo dongosolo wosanjikiza dongosolo, padziko dispersant zabwino ndi zoipa monyanyira kukhala amphamvu kuyanjana ndi madzi, kusintha mlingo wa olimba particles yonyowa ndi madzi. Pakati pa particles olimba amapewa ndi electrostatic inductive repulsion.

4, kupanga dongosolo kasamalidwe symmetrical, zoyandama makhalidwe, palibe mafunsidwe, kuti onse kasamalidwe dongosolo organic mankhwala makhalidwe. Pamwambapa, kugwiritsa ntchito dispersant akhoza stably kumwazikana olimba particles mu madzi boma.
