Mirror roll in most cases refers to the addition of galvanized steel, which is bright white in most cases. Look carefully, the color is a little blue. The functions and advantages of the mirror roll mainly include:
Some of the mirror rolls have a higher hardness standard after using the heat treatment method of aluminum alloy in actual production and processing, while the other metal tubes and round steels with the same steel model are slightly less than those after quenching after other hard processing processes, such as carburizing, nitriding and high-frequency treatment. In actual measurement, the hardness standard of mirror roll is generally between 55 and 65 Rockwell.
The mirror roll has high wear resistance and low friction coefficient. Because the hardness of the pen barrel after chrome plating increases significantly, and the friction coefficient decreases relatively due to the increase of the smoothness, the service life of the product is correspondingly improved. In addition, because the chromium layer remains stable in different environments and is not easy to react, some acid and alkali liquids and gases will not be corroded, greatly improving the acid and alkali corrosion resistance. Once the chrome coating on the surface of the mirror roll is damaged, it can be chrome plated again to reduce costs and reuse.
The installation of the mirror roll is a precise work, which requires care. Attention shall be paid to the installation direction, mirror roll direction and lighting frame position direction during installation. Assembly position: there must be a lamp holder. The polishing frame is assembled in the drum installation and winding installation room, and the mirror wheel frame is provided with a mirror wheel.
The second mirror roller assembly direction: the fabric in the direction of the mirror roller frame must be equipped with cloth guide rollers and roller distribution. The mirror roller bearing smooth cloth machine is equipped with a cooling roller from the shelf, and the mirror roller and one or two rollers on the optical machine frame are equipped. A deviation correction system is set around the roller bearing roller. The mirror roller, the backup roller and the deviation correction system are externally connected, with felt. The two ends of the roller shaft are equipped with pressure regulating mechanisms.
