Description

Technical Field

[0001] The invention relates to the technical field of metal colored stone tile preparation, and in particular to a method for preparing a camouflage gradient color metal colored stone tile. Background Art

[0002] Metal colored stone tiles use metal plates as the base material, with a protective coating applied on the surface to enhance its durability and weather resistance. The colored natural stone particles are then firmly bonded to the metal plates through high-temperature sintering to form beautiful and durable surface tiles.

[0003] The existing preparation methods of camouflage gradient metal colored stone tiles generally only focus on the practicality of the tiles, while ignoring the harmony, diversity and aesthetics of the tiles with the overall house structure. At the same time, they only focus on the basic functions of the tiles such as waterproofing and durability, while the appearance design is relatively simple and lacks variety.

[0004] In view of the fact that the existing camouflage gradient metal colored stone tile preparation method generally only focuses on the practicality of the tiles, but ignores the harmony, diversity and aesthetics of the tiles with the overall house structure, the camouflage gradient metal colored stone tile preparation method sprays colored sand of different colors through multiple sand spreading devices, and vibrates the colored sand through a vibrating screen while spraying, so that the colored sand of different colors are mixed, thereby realizing the gradual transition of the same tile surface from one color to another or more colors. It not only retains the characteristics of the original metal colored stone tiles, but also significantly improves the aesthetics of the tiles and the harmony with the overall structure. Summary of the invention

6. The method for preparing camouflage gradient metal colored stone tiles according to claim 1, characterized in that: When vibrating the vibrating screen, the following steps are included: S601: Check the integrity of the vibrating screen to ensure that the screen is not damaged or blocked, and the vibration motor is working properly. According to the size and shape of the tiles, adjust the screen size and inclination angle of the vibrating screen to meet the needs of different tiles; S602: Turn on the power of the vibrating screen, start the vibrating motor, and observe the vibration of the vibrating screen to ensure that the vibration is uniform and stable without abnormal noise or vibration; S603: According to the material of the tiles, the particle size and distribution uniformity of the colored sand, the vibration frequency and amplitude of the vibrating screen are adjusted. Too high a vibration frequency may cause the colored sand to splash, while too low a vibration frequency may affect the screening effect; S604: During the vibration process, closely observe the distribution of the colored sand on the tile surface. If uneven distribution of the colored sand or excess accumulation of colored sand is found, adjust the vibration parameters in time; S605: When the colored sand on the tile surface is evenly distributed and the excess colored sand has been effectively removed, the power supply of the vibrating screen is automatically turned off, the vibrating screen completely stops vibrating, and waits for the next cycle action; S606: Perform a comprehensive inspection on the tiles after spraying to ensure that the colored sand is evenly distributed without missing any area. If it is found that the colored sand distribution in some areas is inconsistent or there is excess colored sand remaining, adjust the parameters; S607: Use a brush or hair dryer to clean the residual colored sand and impurities on the vibrating screen to ensure that the vibrating screen is clean and free of residue for next use.

7. The method for preparing camouflage gradient metal colored stone tiles according to claim 1, characterized in that: When performing the curing process, the following steps are included: S701: Check the integrity of the curing equipment to ensure that the equipment can work normally, the temperature and humidity parameters are controllable, and prepare the environmental conditions required for curing; S702: After spraying, the tiles are automatically transported to the designated position of the high-temperature curing equipment, ensuring that there is enough space between the tiles for air circulation to avoid the tiles sticking to each other or affecting the curing effect; S703: According to the material properties of the colored sand and tiles, and the design requirements, the temperature and time of the curing equipment are set. The temperature setting needs to take into account the curing temperature of the colored sand and the heat resistance of the tiles to avoid excessive temperature; S704: After confirming that the curing parameter settings are correct, start the curing equipment, start the curing process, observe the operating status of the curing equipment, and ensure that the temperature and time parameters remain stable; S705: During the curing process, regularly check the curing status of the tiles. If any abnormality is found on the tile surface, adjust the curing parameters or stop the curing process in time and check the cause. S706: When the curing time reaches the set value and the colored sand on the tile surface is firmly attached, turn off the curing device, wait for the curing device to cool completely, and take out the tile; S707: Carry out a comprehensive inspection on the removed tiles to ensure that the colored sand is firmly attached to the surface of the tiles without falling off or discoloration. If the curing effect is not satisfactory or there are quality problems, rework or scrapping is required.

8. The method for preparing camouflage gradient metal colored stone tiles according to claim 1, characterized in that: When conducting a quality check, the following steps are included: S801: Prepare necessary inspection tools and clarify the standards and requirements for quality inspection, including the adhesion of colored sand, color consistency, size, shape, surface flatness and hardness of tiles; S802: Visually inspect the overall appearance of the tile to check whether the colored sand is evenly attached to the tile surface without falling off, bubbling or cracking. Then use a magnifying glass to carefully inspect the tile surface to ensure that there are no minor defects. S803: Use a ruler to measure the length, width and thickness of the tile to ensure that it meets the design requirements, and check whether the shape of the tile is regular, the edges are smooth, and there is no deformation or distortion; S804: Compare the tile with the color card to check whether the color of the colored sand is consistent with the design requirements, and observe the tile under different light conditions to ensure that there is no obvious difference or discoloration in color; S805: Perform an adhesion test or use a hardness tester to perform a scratch test on the tile surface to check the adhesion strength of the colored sand; S806: Touch the tile surface with your hand to feel its flatness, and check if there is any unevenness or wave-like phenomenon.
