Common surface treatment of aluminum alloy
Anodize refers to the electrochemical oxidation of metal or alloy, aluminum and its alloy in the corresponding electrolyte and specific process conditions, due to the effect of the applied current, the formation of a layer of oxide film on the aluminum products. Anodic oxidation can not only solve the aluminum surface hardness, wear resistance and other defects, but also extend the service life of aluminum and enhance the beauty, has become an indispensable part of aluminum surface treatment, is the most widely used and very successful process.
Sand blasting is a process to clean and roughen the surface of matrix by the impact of high speed sand flow.Using compressed air as the power, to form a high-speed jet bundle to spray material (copper ore, quartz sand, emery sand, iron ore,) high-speed jet to need to deal with the surface of a product, make products to change the appearance or shape of the surface outside, due to the effect of impact and cutting of the abrasive surface of product, make the product surface to obtain a certain cleanness and different roughness, make the product on the surface of the mechanical performance is improved, thereby improving the fatigue resistance of the product, increase the adhesion between the coating and its, extend the durability of the coating, but also to the flow of paint and decoration.Sand blasting has a strong application in engineering and surface technology, such as: improve the viscosity of adhesive parts, decontamination, optimize the surface burr after machining, surface matte treatment. The blasting process is more uniform and efficient than hand grinding. The metal treatment of this method creates a low-key and durable feature of the product.
Polishing process is mainly divided into: mechanical polishing, chemical polishing, electrochemical polishing.Create a high fashion visual effect.
4.Powder spraying
Electrostatic powder spraying equipment is used to spray powder coating on the surface of the workpiece. Under electrostatic effect, the powder will be uniformly adsorbed on the surface of the workpiece, forming a powder coating. The powder coating becomes the final coating with different effects after high temperature baking, leveling and curing.
Spraying effect in mechanical strength, adhesion, corrosion resistance, aging resistance and other aspects far more than spray painting process.
