As more and more silicone strips become popular in the market, there will inevitably be advantages and disadvantages.Some silicone strips feel that the surface is not smooth enough after being used for a period of time, and they still have a sticky feeling, especially in kitchen utensils.Or the silicone phone case is obvious.What is the reason why the surface of the silicone strip is not smooth?

1.Problems with raw materials, or caused by improper maintenance.

2.It is unreasonable to control and use curing agents in the mixing process of raw materials.The amount of curing agent added is not completely cured, causing the surface of the product to become sticky.

3.During kneading, the curing agent and silicone are stirred unevenly, and the mold is cured at the same time, and the product is deformed due to differences in hardness and hardness after the product is vulcanized.

4.When the machine is cleaned, the mold is not cleaned and the mold is not smooth enough.?Residues in the mold can cause the product to be uneven and make the surface of the product not smooth.

5.No secondary vulcanization?Spraying hand oil, etc., that is, the post-treatment is not enough.

There are problems with the production of silicone strips that are not smooth on the surface. The cause of the occurrence must be found in time and corrected in time, so that the output of a large number of defective products can be avoided, resulting in material waste and affecting production efficiency.
