Ring the aperture of screen cloth；
3, hydrophobicity is strong, and coating does not gets wet, and mud acts directly on the preferable wire screen of lubricity, can weaken mud to sieve
The impact dynamics of cloth, protects wire screen further, it is possible to make wire screen strengthen more than 50% service life；For screen cloth, material can
To sieve more smoothly, it is not easy to blocking mesh；
4, acidproof (except Fluohydric acid .) alkaline-resisting corrosion-resistant, ceramic material, determine the corrosion-resistant stability of coating；
5, high adhesion force, coating has certain pliability and is not easy to come off, has stable insulation effect.
6, self-lubricating makes filter efficiency can reduce vibrosieve shake frequency after improving therewith, and complete machine prolongation in service life is had one
Fixed benefit, moreover it is possible to save complete machine energy consumption；Overall solution, because of vibrosieve problem, improves whole drilling team bit speed, really from root
Improve working performance in basis and reduce cost.
Detailed description of the invention
Below in conjunction with the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described,
