The pressure will be adjusted according to the thickness of the belt when vulcanizing with the belt vulcanizer

Vulcanization pressure of the belt vulcanizer: When the conveyor belt is cemented, the vulcanization pressure is an important condition for the vulcanization of the belt.

Because the pressure can play the following roles in the vulcanization process:

① Improve the compactness and adhesion between the core layer and the rubber material, discharge the gas inside the joint, and eliminate bubbles;

② It can promote the flow of rubber and quickly fill the bonding surface of the core layer;

③ Improve the adhesive strength of the adhesive surface of the tape joint and the bending resistance of the tape.

The vulcanization pressure depends on the properties (mainly plasticity) of the rubber compound, product structure and process conditions. The rubber flow is small, and the vulcanization pressure should be higher; On the contrary, the pressure should be lower. The tape is thick, there are many layers of adhesive tape (core layer), and the structure is complex. If the steel wire rope is the core layer, a large curing pressure should be required.

The influence of vulcanization pressure on vulcanization speed is very small, and generally can be ignored. During on-site vulcanization bonding, the vulcanization pressure of canvas and nylon core tape is 0.8-1.2MPa If the tape is thin, the lower limit shall be selected, and if the tape is thick, the upper limit shall be selected.
