It is very important that products for Stone Garden Decor are treated to resist corrosion. Because stone sculpture are usually exposed to the outdoor environment and are exposed to various natural factors such as air, moisture, rain, and sunlight for a long time, it is easy to cause corrosion and oxidation of the metal surface. For Stone Garden Decor, the problems of corrosion and oxidation are more prominent, because the appearance of Stone Garden Decor is closely related to the luster, color and texture of the metal. Without anti-corrosion treatment, the appearance of the Stone Garden Decor will be damaged, affecting the overall beauty and longevity.
Anti-corrosion treatment refers to special treatment of
stone carving materials to enhance its anti-corrosion performance and prevent corrosion and oxidation. Currently, the commonly used anti-corrosion treatment methods for stone sculpture mainly include the following:
1. Surface coating treatment: The corrosion resistance of the Stone Garden Decor surface can be increased by coating it. Common coating methods include anodizing, electroplating, anode protective coating, etc. These coatings can form a protective film that effectively prevents the penetration of oxygen, water and other harmful substances, thereby slowing down the corrosion rate of stone sculpture materials.
2. High temperature treatment: High temperature treatment can change the physical and chemical properties of the stone carving material and improve its corrosion resistance. For example, commonly used high temperature treatment methods include annealing, solution treatment, etc. These high-temperature treatments can improve the structure of the material, promote the recrystallization of grain boundaries and the growth of grains, thereby enhancing the hardness and strength of stone sculpture and improving corrosion resistance.
3. Anodic protection: Anodic protection can effectively prevent corrosion and oxidation of the stone garden decorative surface. Anodic protection uses a protective film formed by stone sculpture under the action of electric current to protect the metal surface. During use, by applying a forward voltage to the metal surface, a dense chromium oxide film is formed on the metal surface to prevent the penetration and oxidation of oxygen, water and other corrosive media.
4. Thin film coating: Apply a layer of protective coating on the surface of stone sculpture to increase its corrosion resistance. Common thin film coatings include organic coatings and inorganic coatings. Organic coatings can form an isolation film to effectively prevent external corrosive media from corroding stone sculpture; inorganic coatings usually form a dense layer of oxide on the surface of stone sculpture to prevent the penetration and oxidation of oxygen, water and other corrosive media.
The above anti-corrosion treatment methods are commonly used. Different Stone Garden Decor may use different treatment methods. The appropriate treatment method should be selected and adopted according to the shape, material and environment of the stone sculpture. In addition to anti-corrosion treatment, the maintenance and cleaning of Stone Garden Decor is also very important. Regular cleaning and maintenance can extend its service life and maintain its beauty and texture.
