Polishing materials of different materials can use liquid polishing wax with different particles, and can be paired with airway polishing wheels of different hardness. Only by using tools and special high-pressure German style spray guns can a shiny effect be achieved. There are many advantages to high-pressure German spray guns. High pressure spraying can effectively penetrate into the polishing wheel, saving 25% of polishing solution. The high-pressure system can fully penetrate the grinding agent onto the grinding wheel, saving 25% of the cost The waste caused by the rotation of the grinding wheel. Supply can save equipment investment costs, and the spraying range can be as wide as 24 inches. Save the replacement time of polishing wheels. Polishing wheels have a longer lifespan, so reducing the number of times they need to be replaced can also save the time required for replacement It can effectively spray abrasives onto grinding wheels, reducing the generation of dust and lowering the investment and maintenance costs of hard equipment in the pressure supply system. Can ensure polishing quality.
