Related knowledge of chrome rollers

Chrome plating rollers are suitable for various film production lines, paper production lines, large printing equipment, laminating equipment, widely used in flexo printing machines, water-based ink printing machines, laminating machines, coating machines, and can also be used to limit plastics, leather and paper Embossed and frosted.

In most cases, chrome rolls are machined and polished steel rolls with a hard chrome coating on the steel roll body. In most cases, the added coating is bright white. Assuming close inspection, the color is slightly bluish; the thickness of the chrome roller is at least 2 filaments, or 20 microns thick. Otherwise, the hard chrome plating process will not work. The main functions and benefits of chrome rollers are as follows: Roller

1. The advantage of chemical chrome plating roller is high hardness. Compared with the actual production and application environment, the hardness after heat treatment is higher than that of alloy steel, as well as other metal steel pipes and round steels of the same grade. After other quenching processes, such as carburizing, nitriding, high frequency and other processes, it is slightly inferior. In actual measurement, the hardness of chrome-plated rolls is generally between 55-65 Rockwell.

2. High wear resistance and low friction coefficient. Because the hardness of the steel roller body is greatly improved after chrome plating, the friction coefficient decreases relatively with the increase of smoothness, so the service life of the chrome plating roller also decreases accordingly.

3. The ability to resist acid and alkali corrosion is greatly enhanced, because the chromium layer of the chrome-plated roller is very stable in different environments, and it is not easy to produce chemical reactions, so it will not be corroded by neutralized gases in some acid and alkali liquids.

4. Once the chrome-plated layer on the surface of the electroplated chrome-plated roller is damaged, it can be electroplated again, which reduces the operating cost and can be reused.

Because of the above advantages of chrome roller, its application plan is very wide. Most of the machinery and equipment production lines will be used to produce mirror rolls and super mirror rolls. In an environmentally friendly environment, industrial upgrading is the future trend.
