Description

Technical Field

[0002] Thermal silicone sheet is a kind of thermal conductive medium material synthesized by special process with silicone as base material and various auxiliary materials such as metal oxides. Existing thermal conductive silicone gaskets need to filter the glue liquid during production to remove impurities in the glue liquid to ensure the product quality of thermal conductive silicone gaskets.

[0003] The existing glue liquid filtering device only uses the glue liquid to flow through the filter plate in a natural state. Although it can play a filtering role, due to the relatively poor fluidity of the glue liquid, the speed of the glue liquid is slow when passing through the filter holes of the filter plate, resulting in reduced filtering efficiency of the glue liquid; in addition, the filtered impurities will fall on the surface of the filter plate, which is not convenient for manual cleaning. Therefore, a glue liquid filtering device for the production of thermal conductive silicone gaskets is proposed. Utility Model Content
