The type of equipment you mentioned is a laboratory vertical high-speed vacuum dual planetary mixer, specifically designed for medium to high viscosity materials such as silicone adhesives and solder paste. It integrates functions such as high-speed stirring and vacuum defoaming, and is a core equipment for laboratory research and development and small-scale preparation in fields such as electronics and chemical engineering. Here is a detailed introduction:

　　Core working principle

　　The core of this device is the "revolution+rotation" planetary motion mode of dual stirring blades and high-speed dispersing disk. The stirring blade revolves around the axis of the kettle body with the accompanying star frame, and at the same time rotates at high speed, forming strong shear, extrusion, and mixing effects on viscous materials such as silicone adhesive and solder paste; The paired high-speed dispersing disc further disperses the agglomerated particles in the material. At the same time, the equipment is equipped with a vacuum system to extract air from the kettle during mixing, which can effectively remove bubbles generated during material mixing and avoid bubbles affecting product performance such as silicone adhesive bonding strength and solder paste welding stability. Some laboratory models also adopt a 45 degree inclined material cup design, which reduces material residue through non-contact stirring and facilitates cleaning.

　　Key structures and core functions

　　Core functions of structural components

　　The double planet mixing module can choose a variety of blades, such as double Fried Dough Twists paddle and HV claw type. The distance between the blades and the barrel wall is only 3-6mm. It is equipped with a Teflon wall scraper to scrape off the materials on the barrel wall and bottom, so as to realize mixing without dead corners and avoid residual caking of high viscosity materials

　　The vacuum system adopts a two-stage rotary vane vacuum pump and other devices, with a vacuum degree of up to -98kPa or even lower. Some models can maintain a vacuum state for 24 hours, meeting the strict requirements for defoaming materials such as silicone and solder paste

　　The speed of revolution and rotation of the variable frequency speed control system can be independently adjusted. The revolution speed of laboratory models is generally 0-2500rpm, and the rotation speed is 0-6100rpm. The speed can be accurately matched according to parameters such as silicone viscosity and solder paste particle size

　　The temperature control and sealing component barrel body is designed with a jacket, which can be heated or cooled through water and oil circulation, with a temperature error of ≤± 1 ℃; Using wear-resistant sealing rings such as polymer graphene, combined with a fully sealed planetary housing, to ensure a vacuum environment and prevent material contamination

　　The intelligent control system is equipped with a touch screen, which can store multiple sets of programs and support setting parameters such as mixing time and speed. Some models support segmented program settings in 5 stages, and automatically stop after completion, adapting to different experimental processes

　　Adapt materials and laboratory application scenarios

　　This device is particularly suitable for high viscosity materials with a viscosity of up to 4 million CPS and a solid content of less than 90%. In laboratory settings, its core applications include: firstly, in the field of electronics, it is used for the mixing and defoaming of solder paste components, as well as the research and preparation of conductive silicone gel and electronic sealing adhesive; Secondly, in the field of chemical engineering, the formulation of different types of adhesives such as organic silicone adhesives and epoxy adhesives should be adjusted to ensure uniform composition; The third is the field of new materials, such as stirring and dispersion experiments on small batch samples of lithium battery slurry, ceramic slurry, etc. In addition, it can also be used for the experimental preparation of paste like materials in industries such as cosmetics and pharmaceuticals.

　　Typical parameters of laboratory models

　　The laboratory models are mainly miniaturized, with common capacities concentrated in 1-10L. For example, 1L models are mostly designed with double 500ml material barrels, while 5L models have an effective capacity of 2.7-5L, suitable for small-scale experimental needs. In terms of power, the stirring power is generally 1.5-3.5kW, the dispersing power is about 2.2kW, the overall weight is 150-230kg, and the external dimensions are mostly around 1300mm × 1100mm × 700mm. Some parts are equipped with universal wheels for easy laboratory movement.

　　Core strengths

　　High mixing accuracy: Mixing without dead corners and vacuum defoaming can solve problems such as uneven mixing and residual bubbles of high viscosity materials, ensuring the stability and repeatability of experimental samples.

　　Clean and easy to maintain: The parts in contact with materials are mostly made of 304 stainless steel, and some can be sprayed with ceramic materials to reduce pollution. Non contact models only require cleaning the material cup, making material replacement convenient.

　　Strong safety: It has protective functions such as lid opening shutdown, overload alarm, and automatic shutdown due to faults. The sealed design also avoids the risk of splashing and leakage during mixing of high viscosity materials.
