Performance characteristics of Super anti-friction carbonized tungsten coated corrugated roll:
1. The hardness is only second to diamond as well as excellent anti-friction performance.
The life is 3-5 times greater than chrome plated corrugated roll.
Decreased roll change time and cost by 65-80 %( include the stop and change expenses)
Long lasting - Increased time before repair.
Reduce the expense in corrugating cardboard per square by avoiding current depreciation of
related parts caused by concave abrasion (such as glue roll, doctor roll, pressure roll and so on)
2. The consistent quality of corrugating cardboard:
Because of the excellent anti-friction properties, the corrugation height abrasion is between 0.08-0.1mm once in use. Meanwhile, the corrugation pattern won't distort after optimization, and the amount of glue won't increase with the abrasion of corrugation top. So it avoids kinds of limitation of common cardboard, and insures uniform quality of corrugating cardboard.
3. Reduced material consumption and cost of corrugating cardboard
After optimization, the super anti-friction carbonized tungsten coating corrugated roll can reduce the corrugation pattern and result in less paper consumption rate. Less abrasion of corrugation height can decrease paper consumption rate more than 1% when compared to chrome plated corrugated roll.
Decreased abrasion of corrugation top can also lessen the paste consumption create a more stable use. Reduce paste consumption costs by 20-50% !
Greater quality will decrease the wastage loss by 30-50% !
