In the production process of corrugated cardboard, the corrugating rolls of the corrugating machine are the core components for forming. The corrugating rolls need to be continuously heated to 160-220℃, and under high temperature conditions, the paper is pressed into a corrugated shape through pressure to ensure the stiffness and bonding quality of the cardboard. However, this working condition places extremely high requirements on the high-temperature resistance of bearings and lubricating grease.
Bearings are exposed to high-temperature areas for a long time. Ordinary lubricating greases are prone to volatilization and coking, causing carbon deposits to accumulate. This not only pollutes the bearings but may also cause jamming and ablation, leading to equipment shutdown. Frequent replacement of lubricating grease or cleaning of bearings increases maintenance costs and affects production efficiency.
In response to the high-temperature challenges of corrugating roll bearings, the Baoxing engineering team recommends the use of BX-300 series food-grade perfluoropolyether lubricating grease. It has a wide temperature resistance range (-25℃ ~ 300℃) and excellent high-temperature stability. It maintains stable performance in the long-term operating environment of corrugating rolls at 220℃, effectively preventing carbon deposits and coking, and ensuring that the bearing surface is clean without deposits.
It can form a long-lasting lubricating film on the surface, reduce wear, and extend the service life of bearings. It has strong chemical inertness and does not react with metals, seals, or cleaning agents, making it suitable for various high-temperature working conditions.
Compared with traditional high-temperature lubricating greases, Baoxing perfluoropolyether grease has a longer lubrication cycle and more stable performance. It is particularly suitable for corrugated cardboard production lines with strong continuity and high operating speed, helping factories achieve cost reduction and efficiency improvement.
