Description

technical field

[0001] The invention relates to the technical field of ceramic products, in particular to a hydrophobic porous ceramic product and a preparation process thereof. Background technique

[0002] The ceramic industry is one of the oldest industries in my country, and its ornamental value has always been greater than its use value. Nowadays, with the continuous advancement of science and technology, people have higher and higher requirements for the performance of ceramics, which makes the development of various performance Ceramics have become a new research hotspot. Among them, the hydrophobic modification of ceramics is one of the current hot spots. The wettability of solid materials means that when a liquid contacts a solid surface, the liquid can gradually penetrate or adhere to the solid surface, which is one of the important characteristics of the solid surface. This feature is determined by the chemical composition and microstructure of the solid surface. ...
