Everyone is familiar with the polishing process, which can usually be divided into two processes: rough polishing and fine polishing.
For general products, canvas and other fabrics with less fluff are roughly polished for about 3 minutes, and medium or high-fluff hand fabrics are used for fine polishing for about 5 minutes.
It can be done manually or mechanically. Manual polishing requires the use of polishing cloth and polishing agent. First, apply the polishing agent on the polishing cloth and then polish. Mechanical polishing requires the use of electric or pneumatic sandpaper machines to apply the polishing agent to the surface of the carbon fiber product and polish it mechanically. Polishing. After polishing, polishing is also required. Polishing can be done with varnish or wax. By polishing, the gloss of the carbon fiber product can be increased to make it more beautiful.
For rough polishing, cast iron discs can be used, or fabrics with less fluff can be used. When polishing, the carbon fiber plate should be placed steadily, the polishing surface should be parallel to the plane of the polishing disc, and the polishing surface should be evenly pressed on the rotating grinding disc. Start polishing the carbon fiber plate from the center to the edge. Note that the pressure should not be too high. When the carbon fiber plate is finished, it moves from the edge to the center, and the pressure gradually decreases. For rough polishing, only water cooling is needed. No ground polishing abrasive is needed. The humidity of the disc has a great influence on the quality of ground polishing. When the carbon fiber plate leaves the ground polishing disc, the water film on the surface of the carbon fiber plate will evaporate to the most suitable humidity within 1-5. Usually, the rough polishing time is 2-5min, and the standard is that all the scratches generated by polishing on the surface of the carbon fiber plate are removed. After the rough polishing is completed, the sample is cleaned with water or a solution containing a cleaning agent.
For fine polishing, carbon/carbon composite materials generally use 2.5um diamond suspension, diamond grinding paste is also OK, and 1um alumina suspension is added for two polishings. First, use 2.5um diamond suspension wine on medium-neck woolen cloth, add appropriate emulsified lubricant, and polish on a ground polishing machine with a speed of 200-250r/min for 2-3min until all the scratches generated by rough polishing are removed. After polishing, clean the polished surface of the sample with water or a solution containing a cleaning agent.
