  Methods for treating organic substances such as oil stains on metal surfaces:

  2025-06-23

  Dalian metal surface treatment, clean metal surfaces are hydrophilic, so they can be completely wetted by water. When the metal surface contains oil stains, there will be water cut off areas that are not soaked by water. Based on the principle of hydrophilicity, in addition to the simple and commonly used exhalation method and atomizer spray method, there are several detection methods as follows. Due to the hydrophilic nature of metal oxide films, most of these methods cannot detect whether the oxide film on the metal surface has completely removed.

  Degreasing treatment of pre-treatment in Dalian metal surface treatment:

  2025-06-23

  Dalian metal surface treatment is a very important process for metal surface treatment, including degreasing and phosphating. Excellent phosphating solution can only form a phosphating film on the surface of the workpiece after the oil pollution is completely removed. Cleaning agents, due to the residual oil pollution on the surface of the workpiece, not only severely prevent the growth of the phosphating film, but also affect the adhesion, drying function, decoration function, and corrosion resistance of the coating.

  The purpose and importance of metal surface treatment in Dalian:

  2025-05-20

  Nowadays, key technologies for metal surface treatment are present in many industries, followed by innovations in metal surface treatment technology and oil cleaning agent technology. The pre solution of metal surface treatment is an essential process, which also endangers the success or failure of post metal surface treatment. Therefore, the technical aspect of metal pre-treatment plays a crucial role in the technical and engineering projects of metal surface treatment. Today, I will take you to understand the purpose and necessity of solving metal surface problems.

  Introduce the metal surface treatment during the painting process in Dalian:

  2025-05-20

  For metal castings, the commonly used surface treatment methods include mechanical grinding, chemical treatment, surface heat treatment, surface coating, and surface treatment involves cleaning the workpiece surface, removing burrs, oil stains, and oxide scales. The surface treatment of metals is also important in the painting process, which is related to the quality and effect of the painting. Next, I will provide a detailed introduction to the metal surface treatment during the painting process.
