Infrared thermal imager is used for temperature monitoring during supercalendering process

2023-12-27 16:10

Supercalendering is a process in which paper is alternately pushed under pressure into hard and soft rollers to achieve a fine finish. As the process temperature increases, the soft roll cover may overheat and cause the coating to blister or peel off. The maintenance and associated downtime caused by these conditions can add significantly to the cost.

At the same time that the roller is rotating at a high speed, the hot spot will also be generated quickly, and the hot spot location may also be small. When using traditional temperature measurement methods, such as visual detection and point thermometers, it is difficult to quickly capture hot spots, so such applications require responsive and high-resolution equipment.

The infrared thermal imager has obvious advantages in temperature monitoring when used in supercalendering process. It can quickly detect small hot spots, making it the preferred product for temperature monitoring in supercalendering process.

1. The infrared thermal imager is a non-contact temperature measurement method, which can also monitor the temperature without touching the roller, which will not affect the normal production of the roller, nor need to manually contact the high-speed rotating roller, which not only ensures the normal production work but also ensures the safety of personnel;

2, the infrared thermal imager can measure the temperature of multiple points at the same time, it is easier to capture small hot spots, and can monitor the temperature distribution more completely;

3, when the roller is working, the high-speed movement, the hot spot will be quickly generated, the infrared thermal imager is sensitive, can quickly capture the temperature change;

4, the infrared thermal camera can set the alarm temperature, when the temperature rapidly rises may cause fire or equipment failure, once the thermal camera monitors the abnormal temperature, the rapid alarm prompts the staff to deal with, so as to avoid equipment failure or fire risk caused by downtime;

5, the infrared thermal imager can automatically store temperature data, which can be viewed and analyzed by staff at any time, and provide scientific temperature data support for process optimization.

The use of an infrared thermal camera can monitor the temperature change during supercalendering in real time, and help the staff to keep the temperature within the appropriate range, which can improve the paper production process, improve production efficiency, and reduce the risk of equipment downtime.
