Some silicone strips feel that the surface is not smooth enough and sticky after using for a period of time. What is the reason?

       1. Raw material problems, or caused by improper maintenance.

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

       3. The curing agent and silica gel are not evenly stirred during kneading, and the mold is cured while curing, and the product is deformed due to the difference in hardness and hardness after vulcanization of the product.

       4. When the machine is cleaning, if the mold is not cleaned, the mold is not smooth enough. Residue in the mold can cause unevenness in the product and make the surface of the product not smooth.

       5. There is no secondary vulcanization, spraying hand oil, etc., that is, the post-treatment is not enough.

       The surface of the silicone strip is not smooth. It is necessary to find out the cause and correct it in time. In this way, the output of a large number of defective products can be avoided, which will cause material waste and affect production efficiency.
