Methods for improving defects in the production of rubber products

Cause:
1, improper selection of glue;
Solution:
Refer to the rubber design manual to select the appropriate adhesive;
Cause:
2, the metal surface treatment failed, so that the base of the glue coating vulcanization, can not achieve a good physical adsorption with the metal surface.
Solution:
(1) coarsening the metal surface to ensure that the primer slurry can be successfully and tightly attached to the metal surface when vulcanized, and its common treatment methods are: sandblasting and shot blasting of metal inserts in the product;
② The metal surface can not be corroded, can not stick to oil, dust, water droplets and other impurities;
Cause:
3, the glue brushing process stability is poor, the glue is too thin, leakage coating, less coating, residual solvent, etc
Solution:
To ensure that the metal surface has a certain thickness of glue. In this way, on the one hand, it can ensure that the metal surface has sufficient glue and the rubber material entering the mold cavity mutual diffusion and its cross-linking effect is fully carried out, so that the metal surface is fully bonded with the vulcanized rubber;
