Abstract

Fremgangsmåte for dispergering og passivering av finkornede pulvere i vann og vandige medier, er særlig fordelaktig ved håndtering og bearbeiding av oksidfritt pulver, for eksempel innen keramikk- og hardmetallindustrien. Ved fremgangsmåten tilsettes prosessbetinget hjelpestoff. Fremgangsmåten er kjennetegnet ved at det som dette hjelpestoff anvendes polyvinylamin og/eller forprodukt for dette.
