Embodiment 1

[0024] A polishing method for platinum and platinum-rhodium products, the mechanical polishing steps are:

[0025] (1) Take a PtRh10 sample with a thickness of 1.0mm, a length of 400mm, and a width of 200mm.

[0026] (2) Apply polishing paste on the wool felt wheel, the polishing paste is calcium carbonate polishing paste; then install the wool felt wheel on the polishing machine, and the speed of the polishing machine is 800r / min. Put the wool felt wheel close to the PtRh10 plate, and stay on each polished surface for 30s to obtain the polished PtRh10 plate.

[0027] (3) The polished PtRh10 plate obtained in step (2) was immersed in a hydrochloric acid solution with a mass fraction of 10% for 30 min, and then washed with a large amount of pure water.

[0028] Sampling was taken to measure the surface roughness of the sample, and Ra=0.32μm was measured.

Embodiment 2

[0030] A polishing method for platinum and platinum-rhodium products, the steps of ultrasonic polishing are:

[0031] (1) Take a PtRh10 sample with a thickness of 1.0mm, a length of 400mm, and a width of 200mm.

[0032] (2) Prepare a carbon tetrachloride suspension of calcium carbonate at a concentration of 200g / L. Place a sufficient amount of the suspension in an ultrasonic device.

[0033] (3) Suspending the PtRh10 plate in the calcium carbonate carbon tetrachloride suspension described in step (2). Then turn on the ultrasonic equipment, the ultrasonic power is 600W, the ultrasonic treatment time is 120min, and the polished PtRh10 plate is obtained.

[0034] (4) Immerse the polished PtRh10 plate in step (3) in a 12% hydrochloric acid solution for 30 minutes, and then wash it with a large amount of pure water.

[0035] Sampling was taken to measure the surface roughness of the sample, and Ra=0.78μm was measured.

Embodiment 3

[0037] The magnetic polishing steps are:

[0038] (1) Take a PtRh10 sample with a thickness of 1.0mm, a length of 400mm, and a width of 200mm.

[0039] (2) Put the PtRh10 plate into the magnetic polishing equipment. Fill enough pure water into the equipment, start the magnetic polishing machine, and control the speed at 1500r / min to obtain a polished PtRh10 plate.

[0040] Sampling was taken to measure the surface roughness of the sample, and Ra=0.63μm was measured.

Abstract

The invention relates to a method for polishing a platinum product and a platinum-rhodium product, and belongs to the technical field of metal material. The combination of one or more of mechanical polishing, ultrasonic polishing, magnetic polishing and fluid polishing is adopted for the method. The platinum product or the platinum-rhodium product processed through the method is high in surface smoothness and fewer in surface burr, and various scratches generated in the machining process can be removed.

Description

technical field [0001] The invention relates to a polishing method for platinum and platinum-rhodium products, belonging to the technical field of metal materials. Background technique [0002] Platinum and platinum-rhodium products are widely used in the glass industry. Platinum and platinum-rhodium alloys have excellent properties such as high temperature resistance, oxidation resistance, and glass melt corrosion resistance. Currently, there is no other product that can replace them. However, with the rapid development of science and technology, people's requirements for glass are getting higher and higher, and traces of platinum or platinum-rhodium alloy residues in glass will affect the quality of glass. For this reason, it is very important to improve the surface quality of platinum and platinum-rhodium alloy products. Contents of the invention [0003] The object of the present invention is to provide a polishing method for platinum and platinum-rhodium products, wh...
