Our Advantages

The adhesive layer have good elasticity, compression resistance, flex resistance and thermal conductivity.

The maximum tolerance of the hardness should be within the allowable range, otherwise the unevenness of the pulp will be uneven and the quality of the paper will be affected.

Generally, the Shore hardness is 40°~100°, and the tolerance is ±2°~±4°.

Stainless steel rolls body have the following advantages over tin bronze rolls:

1.Has higher rigidity and mechanical strength. Its tensile yield strength and impact toughness are more than double that of copper, which is conducive to improving the dehydration rate.
2.Has higher hardness and abrasion resistance, good impact toughness. It does not deform during long-term high alternating load operation, which is incomparable with copper structure.
3.It has high hardness and abrasion resistance, has extremely high corrosion fatigue strength and ability to resist corrosion cracking and corrosion wear, which is 2-3 times that of copper alloys, and the service life is also increased by more than 2-3 times.
