Product Description

Product Description

Paper Machine Composite Coating Soft Calendering Roll 
 

The compositecover is made of high performance epoxy resin, aramid fiber and high strength mineral filler.
Adding nano mineral filler can improve hardness and ensure more uniform surface properties. The composite material with high safety and fiber reinforcement has high mechanical strength and is not easy to be damaged.

LEIZHAN make sure all raw materials are 100% imported from the world's most advanced products, using the most advanced composite coating technology. Special for soft calendering. Developed unique material formula.

More delicate surface, higher smoothness, higher paper smoothness.

High elastic modulus, quick rebound after compression deformation, long and stable service life, and small grinding amount per time.

Due to the reinforcement effect of aramid fiber, the material has high mechanical strength and is not easy to crack. It is not easy to crack on the roller surface when using in the machine.

Product Parameters

Polyurethane Cover Press Rolll Advantage:
1. The wear resistance is 3 to 5 times than rubber cover; the grinding cycle is longer, the number of broken ends is reduced, and the start-up time is increased.
2. The reinforced composite base layer can withstand the high line pressure of 350KN/M, and can press out the moisture in the paper and felt to the maximum extent.
3. The blind hole + groove design on the roller surface can make the opening rate up to 40%, good resilience, and stable middle-high curve.
4. Short dewatering path in the nip, low water pressure, long service time of the felt, and high bulk of the paper. Under the same working conditions, the dryness of the press section can be increased by more than 2%.
5. It can save 10% of steam and increase the speed by 10%.
