Description

Technical Field

[0001] The invention relates to the field of mixing facilities, and in particular to a silicone adhesive high-speed disperser with a feeding protection function. Background Art

[0002] Silicone glue is a kind of ointment-like material. Silicone glue is divided into two types according to its properties: acidic glue and neutral glue. Acidic silicone glue is mainly used for general bonding between glass and other building materials. Neutral silicone glue overcomes the characteristics of acidic glue that corrodes metal materials and reacts with alkaline materials, so it has a wider range of applications.

[0003] Since silicone adhesive is a mixture of two or more liquid ingredients, stirring equipment is often used to mix the various ingredients during the processing of silicone adhesive. However, in the use of existing stirring equipment, since the stirring part is mostly at the bottom layer of the raw materials, the stirring part cannot directly contact all the raw materials during the stirring process, resulting in insufficient stirring force for the raw materials, which seriously affects the mixing effect.
