What is surface treatment?
Surface treatment is the process of forming a layer on the surface of a basic material with different mechanical, physical or chemical properties from the body.The purpose of surface treatment is to make the product to achieve certain corrosion resistance, wear resistance, decorative or other special functional requirements.
Origin of surface treatment
Surface treatment is one of the oldest techniques. The primitive people lived an extremely hard life, living in groups. In order to survive, they made stone tools and used grinding techniques to make stone tools with sharp edges.In the neolithic age, the stone tools used by primitive people were polished, with delicate and smooth surface and decorative effect, which had become the mainstream of The Times.
In primitive societies, as important as abrasive stone tools were primitive painting techniques.Primitive humans have a sense of beauty, in the late paleolithic age, they used mineral dyes for personal entertainment of small objects for painting.To the neolithic period, the invention of pottery made the development of the original color painting technology to the peak, forming the history of the famous pottery art, opened the prelude of surface treatment painting technology.
How to treat the surface of the product:
We generally speak of surface treatment, may just refer to the product surface that layer of electroplating or treatment results, this is a narrow term, the broader term should include the whole surface treatment of a set of processes.One of the most important aspects is preprocessing.
During the process of processing, transportation and storage, the surface of the workpiece often contains sand, welding slag, dust, oil and other dirt left by the oxide skin and rust mold.To coating can firmly adhere to the surface of workpiece, the workpiece surface before coating must be clean, otherwise, not only influence the adhesion and corrosion resistance of coating and metal, but also can make the matrix metal under even with protective coating can also continue to corrosion, the coating peeling, affect the mechanical properties and service life of the workpiece.Therefore, the surface treatment of the workpiece before painting is an important guarantee and measure to obtain a good quality protective layer and extend the service life of the product.
