Before making a Stone Garden Statues, you need to design the shape first, and then construct the design drawing. There are many adjustments and details in the middle. After completing the above, you can proceed with the processes of creation, splicing, installation, processing, and polishing.
1. The cleanliness of the metal surface seriously affects the bonding strength of the coating layer. Water, oil and other foreign matter remaining or adsorbed on the surface of parts are not clean and often lead to pinholes, nodules, peeling or poor bonding.
2. Based on material considerations, after phosphating treatment, painting should be carried out in a timely manner within no more than 24 hours. Steel parts must be painted within 6 hours after sand blasting and shot blasting. This process measure is a good way to improve the adhesion between the coating and the substrate and improve its corrosion resistance.
3. The oil-water separation in the compressed air for spraying is incomplete, resulting in too much water and oil in the compressed air, which will inevitably affect the quality of the coating and cause various faults and defects. Insist on regular cleaning and replacement of the filter of the oil-water separation facility to keep the compressed air clean and effective. Helps improve coating performance.
4. The ambient temperature and humidity at the
stone carving process operation site have a very obvious direct impact on the performance of the stone carving process film layer. It is necessary to pay attention to maintaining the temperature in the painting construction area within the range of 10~30°C, and the relative air humidity should not exceed 80%. , the work site must be kept clean, hygienic, neat and tidy. If the temperature is too high and the relative humidity of the air is high, the spray paint layer in the coating process will easily turn white and appear orange peel-like. If the temperature is low, the paint layer will flow easily, which will affect the coating process. The quality of products sprayed on the surface of metal materials has a negative impact.
5. The metal surface stone carving process generally uses air spraying. Pay special attention to always keeping the distance between the spray gun and the surface to be sprayed within the range of 200~300mm, and the air pressure at 2~4kg/cm', so as to effectively ensure the quality of the sprayed product.
