METHOD FOR DETERMINING WETTABILITY OF FIBROUS MATERIALS

摘要

FIELD: wettability determining methods and apparatus. SUBSTANCE: method implies measuring of specific sedimentation volume of sediment in liquids of various polarity. Fibrous material is preliminarily condensed under pressure of 0.03-0.5 MPa up to permanent volume and then liquid of various polarity is poured onto material. Period for determining wettability is about 40-60 minutes. EFFECT: high efficiency.
