How to Prevent Corrosion in Dalian Metal Surface Treatment:

Dalian metal surface treatment, due to the presence of phosphoric acid film, can easily penetrate and firmly bond paint with metal. So the phosphating treatment of metals can greatly improve their corrosion resistance and is a common surface treatment method. The application of bio tungstate involves multiple fields in the national economy. It has unique application effects in the automotive industry, home appliance industry, shipbuilding industry, bridge industry, petroleum and natural gas industry, food industry, chemical industry, construction industry, etc.

Surface modification of metals, also known as surface optimization, is the use of new technologies such as ion beams, lasers, and plasmas to change the composition, structure, and properties of the material surface and near surface, in order to obtain new thin layer materials that cannot be obtained by traditional metallurgy and surface treatment techniques, or to make traditional materials have better performance. Selecting different materials to form corrosion-resistant alloys for different purposes, or adding alloying elements to metals to improve their corrosion resistance, can prevent or slow down the corrosion of metals.

Dalian Metal Surface Treatment: After degreasing and rust removal of steel products, they are immersed in a specific composition of phosphate solution to form a layer of insoluble phosphate film on the metal surface. This process is called phosphating treatment. Enamel is a glass enamel with a high content of SiO2, which has good corrosion resistance. Therefore, as a corrosion-resistant non-metallic coating, it is widely used in industrial sectors such as petrochemicals, pharmaceuticals, instruments, and daily necessities.

Reducing the concentration of corrosive media, removing oxygen from the media, and controlling environmental temperature, humidity, etc. can all reduce and prevent metal corrosion. Using the protected metal and another additional electrode as the two poles of the electrolytic cell, with the protected metal serving as the cathode, the cathode is protected under the action of external direct current. Although metal corrosion poses great harm to production, the principle of corrosion can also be utilized to serve production and develop into corrosion processing technology.

The process of Dalian metal surface treatment and simultaneous hot-dip galvanizing production has significant limitations, making it difficult to apply to some large components such as steel derricks and wellbore equipment. However, for complex shaped steel components, they can deform due to the influence of high temperature, thereby affecting their function. The anti-corrosion principle of arc spraying layer is a combination of cathodic protection and mechanical shielding. However, due to the particularity of gas underground, electric arcs are prone to causing gas explosions, making this technology difficult to apply underground.
