METHOD OF CREATING GAS LIQUID BOUNDARY FACE OF SOLID PARTICLE AND SOLID PARTICLE HAVING SUPER WATER REPELLENT COATING FILM FORMED BY THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method of preventing the settlement and deposition of solid particles in a liquid without limiting the combination of a liquid with the solid particles and the physical condition thereof, that is to provide a method of increasing the buoyancy of the solid particle in the liquid. SOLUTION: The buoyancy of the solid particle in the liquid is increased by forming a super water repellent coating film on the surface of the solid particle to form a gas phase film on the outer layer of the surface of the solid particle to create a gas liquid boundary face and bringing the solid particle into contact with the liquid through the gas phase film when the solid particle is dipped into the liquid. The solid particle having the super water repellent coating film formed by the method is provided. COPYRIGHT: (C)2004,JPO
