In 2021, the company reached a cooperation with NOF Company and signed a Geomet coating authorization agreement.
]]>Product performance
1. Meet environmental protection requirements
It does not contain toxic elements such as hexavalent chromium (Cr6 +, heavy metals (CD, Pb), etc., with low VOC and various water-soluble and heavy-duty anti-corrosion systems.
2. Lubrication function
]]>Anticorrosion technology of chromium free metal:
1. Hydrogen free embrittlement: the metal treatment process determines that there is no hydrogen embrittlement in the metal, so the metal is very suitable for the coating of stressed parts.
2. High heat resistance: the metal can resist high temperature corrosion and heat resistance temperature can reach above 300 ℃. When the traditional galvanizing process temperature reaches 100 ℃, it has been peeled and scrapped.
3. Good adhesion and recoating performance: the metal coating has good adhesion with the metal matrix and strong adhesion with other additional coatings. The treated parts are easy to be painted and the adhesion with organic coating is even greater than that of phosphating film.
]]>Zinc aluminum coating process in order to achieve the purpose of coating, we should not only consider the use and performance of the coating itself, but also consider the coating construction process, because the performance and role of the coating are reflected by the coating, each coating and coating process has its own characteristics and scope of application, matching properly or not directly affects the coating quality, different coatings should choose different coating. Technology. The coating process of zinc aluminum coating is as follows:
Hanging up > degreasing > spraying > cleaning > ultrasonic cleaning > drying > automatic spraying > curing > cooling > hanging down
After pre-treatment, the workpiece enters the spraying station, and the spray gun is installed on the adjustment frame in the closed spraying room. According to different workpiece, the position of the spray gun can be adjusted. In order to spray evenly, the ground conveying system is adopted, and the workpiece is installed on the tray. Driven by the driving devices on both sides, the spray gun starts to rotate automatically in the moving process. When entering the effective position of the spray gun, the spray gun will automatically open and start spraying. When a certain thickness is reached, the spray gun stops spraying. The workpiece continues to move to the next curing process.
Curing for better curing, the coating needs to be preheated before curing, including preheating chamber and curing chamber. The preheating chamber is set in the inlet section of the workpiece, and the rated temperature of the preheating area. , the curing chamber is directly connected with the preheating chamber, and the rated temperature of the curing zone '.
