Why silicone and plastic vulcanization in the mold will appear part stick, part not stick?

08 Aug 2019 - silicone and plastic vulcanization in the mold will appear

According to various silicone adhesive experiments, kanglibang silica gel glue business department gives the following schemes:

1, the plastic surface is not clean, that is, some of the plastic is clean, some of the oil, dust, etc., resulting in silicone and plastic non-stick (after cleaning, just go to the machine)

2. Uneven coating of silica gel glue (silica gel treating agent) on the plastic surface leads to non-adhesion between silica gel and plastic;(kanglibang silicone glue can be used to spray, brush and soak plastic surface)

3. Apply the surface treatment agent on the plastic in time. If there is grease or a lot of water on the hands of the operator, grasp the plastic parts, resulting in non-adhesion of the plastic parts and silica gel

4, plastic parts have a combination of different parts, there is crack in the middle, the silicone material is placed in the computer, didn't pay attention to the places in the gap left interval, cause at the time of closing the gap of the air inside of plastic parts can't discharge, cause the crack location on bubble plastic and silicone non-stick (put silica gel material, cut the silicone in gap position);

5, the plastic material is not uniform, resulting in silicone glue can not activate its molecules, resulting in plastic and silicone non-stick.
