Sand Blasting Nozzle of Polycrystalline Diamond

Description

The nozzle made of polycrystalline diamond(PCD) has an unprecedented high wearproof property. The PCD nozzle developed by our company is characterized with the features of reliable performance and very long life, and its life is ****0 times than that of boron carbide nozzle, and ******0 times than that of hard alloy (WC-Co) nozzle. ã??ã??PCD nozzle is composed of synthetic polycrystalline diamond core and wrap. PCD is the working part of nozzle and is synthesized through sinter of synthetic diamond powder under the condition of ultrahigh pressure and high temperature (*0, **0 atmospheric pressure, ***0â??****0â??). The metal or plastic wrap will not only make a more accurate external size but also protect PCD core. ã??ã??The effect comparison test shows that PCD nozzle has strong advantages and obvious performance-value ratio. And the test result is described as follows: ã??ã??Select the hard alloy nozzle, boron carbide nozzle and PCD nozzle with inner bore of 6mm and Ñ?*0Ã?*5mm for a comparison, and conduct sand blast finish to the metal surface with high hardness with green silicon carbide with grain size of *4 meshes. Hard alloy nozzle may be used for ***0 shifts; boron carbide nozzle may be used for ****0 shifts; and the service life of PCD nozzle is more than ***0 shifts. ã??ã??We can offer the straight aperture sand blasting nozzles of various specifications; and refer to the following table for the key specifications. And special tailoring is also available according to clientsâ?? special requirements.
