Nov 15, 2024
Mechanical treatment
1. Frosting: Use tools such as sandpaper, sanding belt or grinding wheel to polish the surface of Tin Pail to make it present a delicate frosted texture. This process can increase the friction of the surface and make the surface of Tin Pail more non-slip. It is often used in some Tin Pails that need to increase friction, such as Tin Pail used to store tools and parts.
2. Wire drawing: Through wire drawing machine or manual wire drawing, a continuous filamentous texture is formed on the surface of Tin Pail. The wire drawing process can make the surface of Tin Pail present a unique metallic luster and texture, increase the beauty of the product, and is often used in some high-end Tin Pail, such as Tin Pail used for decoration, gifts, etc.
3. Polishing: Use a polishing machine or manual polishing to polish the surface of Tin Pail to make it smooth as a mirror. The polishing process can improve the surface gloss of Tin Pail and make it more beautiful. It is often used in some Tin Pails that require high gloss, such as Tin Pail used for display, collection, etc.
4. Shot peening: Use compressed air to spray the projectiles onto the surface of the Tin Pail at high speed, so that tiny pits are produced on the surface, thereby increasing the surface roughness. The shot peening process can improve the surface hardness and wear resistance of the Tin Pail barrel, and is often used in some tin barrels that need to improve wear resistance, such as tin barrels used in industrial production, transportation, etc.
Chemical treatment
1. Pickling: Soak the tin barrel in the pickling solution to remove impurities such as oil, oxides and rust on the surface, thereby improving the surface cleanliness of the tin barrel. The pickling process can make the surface of the tin barrel smoother and prepare for the subsequent surface treatment process. It is often used in some tin barrels with more oil, oxides and rust on the surface.
2. Alkaline washing: Soak the tin barrel in the alkaline washing solution to remove impurities such as oil, oxides and rust on the surface, thereby improving the surface cleanliness of the tin barrel. The alkaline washing process can make the surface of the tin barrel smoother and prepare for the subsequent surface treatment process. It is often used in some tin barrels with more oil, oxides and rust on the surface.
3. Passivation: Soak the tin barrel in the passivation solution to form a dense passivation film on the surface, thereby improving the corrosion resistance of the tin barrel. The passivation process can make the surface of the tin barrel smoother and prepare for the subsequent surface treatment process. It is often used in some tin barrels that need to improve corrosion resistance, such as tin barrels used to store chemicals, food, etc.
4. Electroplating: Use the tin barrel as a cathode and put it into the electroplating solution containing metal ions. By electrolysis, a layer of metal plating is deposited on the surface of the tin barrel, thereby improving the surface hardness, wear resistance, corrosion resistance and decorativeness of the tin barrel. The electroplating process can make the surface of the tin barrel present different colors and glosses. It is often used in some tin barrels that need to improve surface performance and decorativeness, such as tin barrels used in the automotive, home appliances, electronics and other industries. Commonly used electroplated metals are chromium, nickel, zinc, copper, etc.
Coating treatment
1. Spray paint: Spray the paint evenly on the surface of the tin barrel through a spray gun to form a protective film, thereby improving the corrosion resistance, wear resistance and decorativeness of the tin barrel. The spray painting process can make the surface of the tin barrel present different colors and glosses, and is often used in some tin barrels that need to improve surface performance and decorativeness, such as tin barrels used in furniture, construction, machinery and other industries.
2. Baking paint: Spray the paint evenly on the surface of the tin barrel through a spray gun, and then put the tin barrel into the baking room for baking, so that the paint solidifies to form a protective film, thereby improving the corrosion resistance, wear resistance and decorativeness of the tin barrel. The baking paint process can make the surface of the tin barrel present different colors and glosses, and is often used in some tin barrels that need to improve surface performance and decorativeness, such as tin barrels used in the automotive, home appliances, electronics and other industries.
3. Plastic coating: The plastic powder is evenly coated on the surface of the tin barrel by electrostatic spraying or fluidized bed coating, and then the tin barrel is placed in the baking room for baking, so that the plastic powder solidifies to form a protective film, thereby improving the corrosion resistance, wear resistance and decorativeness of the tin barrel. The plastic coating process can make the surface of the tin barrel present different colors and glosses, and is often used in some tin barrels that need to improve surface performance and decorativeness, such as tin barrels used in the chemical, food, pharmaceutical and other industries.
Other treatments
Etching: Use chemical etching liquid or laser etching to etch various patterns and texts on the surface of the tin barrel, thereby increasing the beauty and artistic value of the tin barrel. The etching process can make the surface of the tin barrel present a unique effect, and is often used in some tin barrels that require personalized design, such as tin barrels for gifts, crafts, etc.
1. Laser carving: Use a laser laser engraving machine to engrave various patterns and texts on the surface of the tin barrel, thereby increasing the beauty and artistic value of the tin barrel. The laser carving process can make the surface of the tin barrel present a unique effect, and is often used in some tin barrels that require personalized design, such as tin barrels for gifts, crafts, etc.
2. Thermal transfer: Use a thermal transfer machine to transfer the pattern and text printed on the thermal transfer paper to the surface of the tin barrel, thereby increasing the beauty and artistic value of the tin barrel. The thermal transfer process can make the surface of the tin barrel present rich colors and patterns, and is often used in some tin barrels that require personalized design, such as tin barrels for gifts, crafts, etc.
