The causes and solutions of rubber Marine fender rolling effect, let's take a look at the causes and solutions of rubber Marine fender rolling effect:

Shrinkage deformation: calendering produces longitudinal shrinkage deformation, length decreases, and section thickness increases.

Cause: The macromolecular chain is produced during calendering

Calendering effect: The calendering film will also show anisotropy in performance.

Causes: The macromolecular chains are stretched and deformed and oriented during calendering, and the flow direction and orientation of the complex with asymmetric geometry are arranged.

preventive measure.

1. Properly increase the surface temperature of the calender roll and the parking temperature of the calender semi-finished product

2. Slow down the rolling speed

3. Appropriately improve the plasticity of the compound

4. Turn the hot-tempered film 90 degrees to the calender for rubber, or turn the film 90 degrees to load the vulcanization model for vulcanization

5. Try not to use a few boxes of particles with asymmetric shapes.
