Dalian metal plastic coating dries slowly in winter and is prone to sagging, or the primer is not dry, which affects the assembly line operation. Water based coatings, including water-based metal pigments, and aluminum silver paste itself dry slowly, making natural drying difficult in winter. How to prevent sagging and other phenomena? Actually, doing electric hot air blowing treatment and adding hot air circulation to the automatic line can effectively improve it. Coatings contain benzene derivatives such as benzene, toluene, xylene, etc.

By mixing resin and rubber, lightweight and high-strength automotive components can be produced. A research team in Japan is advancing the study of using CNF to replace iron car bodies and frames. If vehicle lightweighting can be achieved, fuel economy will be improved. The emission of carbon dioxide will also decrease. In the long run, it may even be possible to use carbon fiber to manufacture aircraft bodies.

Metal surface spraying is currently a commonly used technology because with the widespread application of metal products, people's demand for the quality of metal products is constantly increasing, which will inevitably lead to the synchronous development of the metal spraying industry. Nowadays, the metal spraying industry is thriving, and there is also an effective inspection method for the quality of metal spraying. Evaluating products by checking whether the quality of metal spraying is up to standard is also an important aspect. I would like to take this opportunity to talk to you about the quality inspection standards for metal spraying.

Dalian metal surface treatment can be divided into four aspects:

Mechanical surface treatment: sandblasting, shot blasting, polishing, rolling, polishing, brushing, spraying, painting, oil coating, etc.

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.  

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.
