Description

[0002] Stirring is the mixing of different substances to achieve uniform dispersion. It is usually achieved by rotating, shaking or stirring. Stirring can be applied in various fields, including food processing, chemical engineering, pharmaceuticals, materials science, etc.

[0003] When processing silicone materials, different raw materials need to be mixed. In order to improve the efficiency of raw material mixing, a stirring device is usually used to stir the raw materials. However, when the existing stirring device stirs the silicone raw materials, the movement of the stirrer will mix air into the silicone raw materials, causing bubbles to form inside the raw materials after mixing. If these bubbles are not removed in time, they will remain in the silicone during the silicone curing process to form pores, affecting the performance and surface quality of the silicone. In addition, the existing stirring device cannot control the amount of raw materials added when adding raw materials, resulting in uneven or broken silicon-oxygen bonds in the silicone structure, which reduces the overall strength and toughness of the silicone.
