Latex tube in the production of over vulcanization reasons and treatment
Over-vulcanization leads to the product surface discoloration, smaller holes, higher hardness, product edge cracking.
Causes: improper operation or vulcanization temperature is too high, vulcanization time is too long or the instrument is out of order;
Solutions: check whether there is any problem with the valves and instruments; to strictly implement the operating rules.
Latex tube in the production of under vulcanization reasons and treatments
Latex products vulcanization is insufficient, out of the mold pressure inside the pore is greater than the external pressure, the rubber material if you continue to send a hole, the light is caused by the hardness of the low, the strong sex is poor, the deformation of the big; heavy eyelet burst.
Solution: check whether the instrument, valve problems; strict implementation of the operating rules.
