Question 2

What aspects should you pay attention to when purchasing an impregnation line?

Accepted Answer

If we only look at the appearance, almost every impregnation line looks "similar". In fact, when buying an impregnation line, we should not only look at the appearance, but also the inner core. In addition to the price, we need to pay special attention to the following aspects:

Energy saving
Energy saving actually means saving money for the enterprise. How to test energy saving?
Oven structure: At first glance, almost every oven "looks the same". However, the internal structure is definitely different. The structure of some companies’ ovens has never changed, and it is still a very old and outdated design. The design of some companies’ oven structures has been updated for several generations. Every optimization and upgrading of the internal structure is to improve the efficiency of energy utilization and reduce costs and increase efficiency for the enterprise.

Stability
Most impregnation lines are running 24 hours a day, so the stability of the entire production line is crucial. How to test stability? Go to the production line for field inspection, and stay in the workshop for a month if you have enough time. Some impregnation lines will have many problems in a day, either paper breaks, or there are black spots, or the glue coating is uneven, resulting in the production of substandard paper. There are so many problems that it collapses, and it has to stop from time to time. It wastes paper and manpower, which has a great impact on production. Some impregnation lines can be kept running for weeks or months without stopping, and the quality of paper output is stable. In fact, stability cannot be seen from the equipment configuration parameters alone. It has a lot to do with the level of adjustment ability of the impregnation line company on the entire production line.

Coating accuracy
The coating accuracy directly affects the quality of paper. How to ensure that the quality of the product is not compromised without slowing down the speed, the coating accuracy of the coating unit is crucial. Similarly, the best way to test the coating accuracy of the impregnation line is to go to the first-line production workshop. Look at the produced paper, look at it, touch it, and truly feel the quality of the paper.
