Problems solved by technology

[0002] Because the existing faucet ceramic valve plate is made of ceramic material prepared by conventional technology, it is prone to wear and tear after a long time of use, resulting in incomplete closure and affecting watertight performance, especially for faucets or faucets used in sewage and high water pressure environments. Water valve, if the conventional ceramic valve plate is used, it is very easy to be eroded by sand and gravel, which will affect the service life of the faucet

Abstract

The invention discloses a preparation method of an anti-wear water faucet ceramic valve block. The preparation method comprises the following steps: (1) preparing dolomite micro powder and aluminum oxide micro powder; (2) uniformly mixing the prepared dolomite micro powder and aluminum oxide micro powder with zirconium silicate powder with an average particle size of 0.3 to 0.5 micron, and performing compression molding and suffocating; (3) putting a suffocated ceramic valve block blank into a kiln for sintering, immersing the ceramic valve block blank into praseodymium-neodymium alloy powder slurry for ultrasonic treatment after the ceramic valve block blank is cooled, putting the ceramic valve block blank into the kiln again for sintering, and grinding and polishing the ceramic valve block blank after the ceramic valve block blank is cooled to normal temperature to obtain the anti-wear water faucet ceramic valve block. The preparation method has the advantages of being capable of prolonging the service life of a water faucet or a valve and being capable of resisting wear.

Description

technical field [0001] The invention relates to a preparation method of an anti-wear faucet ceramic valve plate. Background technique [0002] Because the existing faucet ceramic valve plate is made of ceramic material prepared by conventional technology, it is prone to wear and tear after a long time of use, resulting in incomplete closure and affecting watertight performance, especially for faucets or faucets used in sewage and high water pressure environments. For the water valve, if the conventional ceramic valve plate is used, it is very easy to be eroded by sand and gravel and affect the service life of the faucet. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the above shortcomings of the prior art: to provide a method for preparing a faucet ceramic valve plate used in a water faucet or a valve, which can prolong the service life of the water faucet or valve and resist wear. [0004] The technical solu...
