Why is MJ coating environmentally friendly

Magni coating is a two-layer coating system without chromium, which combines inorganic zinc rich bottom layer with organic aluminum rich outer layer. The bottom layer provides cathodic protection for the steel matrix, while the outer layer contains lubricants, pigmented polymer resin (resin), and other components to provide the characteristics of sliding, acid and alkali resistance, aesthetics, and establish a lasting protective barrier. The corrosion resistance of the applied force is equivalent to that of hot-dip galvanizing, but the weight of the components is greatly reduced. Compared with hot-dip galvanizing, the coating system is lighter and can be used as an independent system, and also as the base of other protective outer layers. In Asia, Toyota, hodanissan, Hyundai, and Mitsubishi companies have adopted the Mecca non chromium coating process to carry out anti-corrosion treatment for automotive standard parts. It has been proved that the coatings and coating process can meet the special needs of automobile and other high anti-corrosion requirements, and can extend the service life of products in the worst environment. And the coating process of our company is of high quality and low price.

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

What is the best anticorrosion technology of metal coating

The application of metal coating technology in industrial production activities should not need us to say more. What are the advantages of metal coating? This is curious for many people. Let's elaborate on the use of chromium free metal for you. I hope our introduction will help you!

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.

What is the purpose of zinc aluminum coating process

In many basic accessory surfaces, we will add an additional layer of coating, not only for aesthetic decoration effect, but also to protect accessories. After long-term use in the later stage, it will not rust or damage, so how to choose the coating? Or what is the difference and contrast between different layers? Today, we will give you an example of a widely used zinc aluminum coating, which is used on the new metal surface to play a role in anti-corrosion. Through early brush coating or spraying and later baking processing operations, we can attach the zinc aluminum coating materials perfectly on the surface of accessories. Next, let's learn about the zinc aluminum coating with the editor.

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 '.
