In the development process of China, metal surface treatment belongs to a relatively long history of technology, from the moment people found that there has been a metal surface treatment technology. Ancient people can produce all kinds of stone tools, and can treat their metal surface into a sharp shape. In the Neolithic age, it was able to finish the metal surface treatment of the equipment made by primitive human beings into a fine and smooth shape. In addition, it also paid attention to the actual effect of decoration design. The development trend of metal surface treatment is very fast, and the development trend of Dacromet surface treatment process is also very fast. Metal surface treatment is particularly important for people's daily life, and people's normal daily life can not do without metal surface treatment.
To put it bluntly, metal surface treatment refers to the maintenance effect on the surface layer of basic raw materials after being solved according to various organic chemistry and physical resources. In order to better consider the corrosion resistance, wear resistance of goods, or for better decoration design and other functions, so that we can do a variety of solutions to the surface of many goods. Metal surface treatment methods include: mechanical equipment polishing method, organic chemical treatment method, surface heat treatment Dacromet process method, painting surface method.
Generally speaking, there are two expressions of metal surface treatment: theoretical metal surface treatment and category surface treatment. Theoretical metal surface treatment refers to: pre solution, electroplating process, spraying, organic chemical air oxidation, thermal spraying and other solutions; And the category of metal surface treatment refers to: sandblasting and polishing methods. Naturally, Dacromet surface treatment process can be divided into these two methods, only it has some properties.
Let me talk about the methods of metal surface treatment in detail
1、 Metal surface treatment before spraying, in order to better eliminate the oil stains, dust, embroidery, etc. on the surface of the object, the preparation of the surface of the object is carried out first.
2、 Hand made solutions, such as using scraper, steel brush or sand wheel to solve the surface of the object. The disadvantages of handmade solution are: great labor efficiency, low productivity, weak solution quality and incomplete cleaning.
3、 Organic chemistry solution. Organic chemistry solution generally uses acid-base or alkaline solution to produce chemical changes with metal oxides, oil stains and dust on the surface of objects, so as to eliminate the residue on the surface of objects. Dacromet surface treatment process can also choose the above three methods.
Above is my detailed introduction of metal surface treatment and Dacromet surface treatment process, which is expected to help you master metal surface treatment and Dacromet surface treatment process.
