  Dalian metal plastic spray painting steps:

  2024-07-18

  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.

  The advantages of passivation in Dalian metal surface treatment:

  2024-06-24

  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.
