Dispersant wakili ne mai aiki na tsaka-tsaki tare da kaddarorin kishiyoyi biyu na lipophilicity da hydrophilicity a cikin kwayoyin halitta.

Watsawa tana nufin cakudar da aka samu ta hanyar tarwatsa wani abu (ko abubuwa da yawa) zuwa wani abu a cikin nau'in barbashi.

Dispersants iya uniformly tarwatsa m da ruwa barbashi na inorganic da Organic pigments da wuya a narke a cikin taya, da kuma hana sedimentation da condensation na barbashi, forming amphiphilic reagents da ake bukata ga barga suspensions.Houhuan sinadaran R & D da kuma samar da ruwa na tushen Additives da mai tushen Additives a daban-daban masana'antu, alaka surfactant Categories.

An rarraba tsarin watsawa zuwa: bayani, colloid da dakatarwa (emulsion).Don mafita, solute shine tarwatsawa kuma sauran ƙarfi shine tarwatsawa.Misali, a cikin maganin NaCl, mai rarraba shine NaCl, kuma mai rarraba ruwa ne.Mai watsawa yana nufin kayan da aka tarwatsa cikin barbashi a cikin tsarin watsawa.Wani abu kuma shi ake kira watsewar abu.

Ayyukan yin amfani da tarwatsa pigment na masana'antu sune kamar haka:

1. Yi amfani da wetting dispersant don rage lokaci da makamashi da ake bukata don kammala watsawa tsari, tabbatar da tarwatsa pigment watsawa, PP mannewa talla, gyara surface Properties na pigment barbashi, da daidaita motsi na pigment barbashi.

2. Rage tashin hankali tsakanin ruwa-ruwa da m-ruwa.Watsawa kuma su ne surfactants.Masu rarraba sune anionic, cationic, wadanda ba ionic, amphoteric da polymeric.Daga cikin su, ana amfani da nau'in anionic mafi yawan.

3. Watsawa wani wakili mai taimako wanda zai iya inganta rarrabuwar kayan abu mai ƙarfi ko ruwa.
