Dalian metal and plastic spray painting knowledge, metal surface spray painting is a method to protect metals from oxidation and corrosion. 

In the metal surface coating process, the firm adhesion of the paint film to the substrate can play a role in protection, decoration, and corrosion prevention. The firm adhesion of paint film on metal surface is closely related to the roughness, thermal expansion and contraction coefficients of the coated substrate surface. Generally speaking, when the surface is too smooth or the temperature coefficient of change between the paint film and the substrate is significantly different, the adhesion of the paint film will deteriorate, and it is common for the paint to peel off from the metal substrate.

With the advancement of technology, spray painting can be completed through Dalian metal plastic spray painting, which not only greatly improves work efficiency but also significantly improves the spray painting effect. Do you know how to measure spray painting equipment? Now let the paint spraying equipment manufacturer answer each question for you one by one.

Dalian metal surface treatment is a process method of artificially forming a surface layer on the surface of the substrate material that has different mechanical, physical, and chemical properties from the substrate. The purpose of surface treatment is to meet the corrosion resistance, wear resistance, decorative or other special functional requirements of the product. For metal castings, the commonly used surface treatment methods include mechanical polishing, chemical treatment, surface heat treatment, spray coating, etc.

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.
