Mixing Machine | How to select the mixing mixing and dispersing machine?
The role of pre-dispersion is as follows:
1. Mix all kinds of pigments and liquid paint paste evenly
2. The paint paste replaces the air adsorbed on the surface of some pigment particles, so that the pigment can be partially moistened
3. Make the large pigment particles initially depolymerize to shorten the working time of the next grinding and dispersion and improve the dispersion efficiency.
This process, although called mixing, also has a dispersive effect. At present, the most widely used mixing equipment in the chemical industry is the high-speed disperser, the high-speed disperser is also known as the high-speed mixer or stirring and dispersing machine, etc., its use is generally with the sand mill or three-roller grinder and other grinding and dispersing equipment, for the early mixing and pre-dispersion. For some materials that are easier to disperse or products that do not require high dispersion fineness, high-speed dispersers can also be used directly as grinding and dispersing equipment, and the materials with low viscosity are normally stirred for 35-40 minutes, and the fineness of the materials can reach 40-80 microns. In addition, if it is a platform disperser, it can also be used as a daily small batch storage or paint dispensing equipment.
In addition to the high-speed disperser, we can also choose other mixing (or pre-dispersion) equipment, including dual-shaft high-speed disperser, concentric biaxial high-speed disperser, disc type double shaft mixing and dispersing machine and disc type three-axis mixing and dispersing machine, etc., and can also customize a variety of different types of mixing blades according to the actual production process requirements, such as disc blades, word paste, curved blade turbines, blade removal turbines, propulsion, Brumakin, anchors, frames, screws, etc. Choose your own mixing form to produce more efficiently.
We then from the material adaptability viscosity range, high-speed disperser and dual-axis high-speed disperser suitable for lower viscosity; (such as fluorocarbon paint, furniture paint, automotive paint, marine paint, latex paint, etc.), concentric biaxial high-speed disperser suitable for medium viscosity; (U.S. seaming agent, automotive chassis armor paint, heat dissipation silicone grease, etc.), dual-axis high-speed disperser suitable for medium and high viscosity; (atomic ash, offset printing ink, lithium battery materials, etc.), and three-axis high-speed disperser can be suitable for high viscosity (printing glue, liquid silicone, ink, Electronic pastes, etc.), in short, the above equipment can be competent for the mixing of various materials in the production of coatings.
