Sand Blasting Nozzle Of Polycrystalline Diamond(pcd Nozzle)

We offer a wide range of Sand blasting nozzle of polycrystalline diamond(PCD nozzle) to our customers. 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 15-20 times than that of boron carbide nozzle, and 150-200 times than that of hard alloy (WC-Co) nozzle.
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 (60,000 atmospheric pressure, 1400a -1500a ). The metal or plastic wrap will not only make a more accurate external size but also protect PCD core.
The effect comparison test shows that PCD nozzle has strong advantages and obvious performance-value ratio. And the test result is described as follows:
Select the hard alloy nozzle, boron carbide nozzle and PCD nozzle with inner bore of 6mm and N 20A 35mm for a comparison, and conduct sand blast finish to the metal surface with high hardness with green silicon carbide with grain size of 24 meshes. Hard alloy nozzle may be used for 8-10 shifts; boron carbide nozzle may be used for 70-80 shifts; and the service life of PCD nozzle is more than 1000 shifts.
We can offer the straight aperture sand blasting nozzles of various specifications.
