The sandblasting process of Chalaat mirrors can achieve better cleaning effect by spraying sand particles at high speed to remove dirt or coating on the surface of the object, and at the same time increase the microscopic roughness of the surface of the object to facilitate subsequent treatment such as spraying or painting.
Sandblasting can enhance the durability of the mirror and make the back surface of the mirror rough. Compared with the smooth surface, the subsequent coating or plating can adhere more firmly, making the mirror more "resistant" in complex and changing environments, reducing the risk of falling off, and ensuring the stability of the mirror for long-term use.
