Research on rheopexy properties of the EPC coating

摘要

The physicochemical properties and structure of Jia-shan Anhui attapulite clay have been studied by various kinds of measurements.By using NXS-11 model rotary viscometer,the rheopexy of the suspension liquid of atapulgite clay and its influences on EPC coating's rheopexy h=behaviors are investigated.And a mathematical model on the rheopexy has been obtained.The results hsow that attapulgite clay is one of better rheopexy used in water based EPC coatings.
