Surface treatment of ceramic sand semi-finished products includes the following steps:
1. Cleaning: Use water or appropriate cleaning agent to clean the surface of ceramsite sand semi-finished products to remove dust, dirt or other impurities on the surface.
2. Preheating: When the surface temperature is moderate, put the ceramsite sand semi-finished product into the furnace for preheating treatment to increase its surface hardness.
3. Sandblasting treatment: Use a sandblasting machine to spray high-speed airflow onto the surface of the ceramsite sand semi-finished product to remove surface defects, scale and impurities, while increasing the surface roughness.
4. Coating: Apply a layer of metal or non-metal coating, such as epoxy resin, polyester resin, polyurethane, etc., to the surface after sandblasting to improve the corrosion resistance and wear resistance of the surface.
5. Curing: Curing the coating at appropriate temperature and pressure to ensure that the coating is firmly bonded to the surface of the ceramsite sand semi-finished product.
6. Post-processing: After the surface treatment is completed, some post-processing work is performed as needed, such as shaping, polishing, etc.
The specific surface treatment method should be determined based on the material, use and actual needs of the ceramsite sand semi-finished products.
