According to table 2, the abrasion index of the friction tube 4 is obviously increased after the carborundum is added, the abrasion index is in an increasing trend along with the increase of the addition amount of the carborundum, and meanwhile, the static friction coefficient of the friction tube 4 is not obviously changed and has no obvious negative effect after the carborundum is added, and the abrasion of the friction tube 4 is favorably reduced, and the service life is prolonged.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
