Analysis of the Principle of Plastic Color Mixer
Mixing machine is the use of mechanical force and gravity, etc., will be two or more materials evenly mixed with the machinery. Widely used in various industries and daily life. Today Guangfeng vertical blending machine Xiaobian to tell you about the principle of Plastic Color Mixer.
Mixing machines can mix a variety of materials into a homogeneous mixture, such as cement, sand, gravel and water mixed into concrete wet material; also can increase the material contact surface area to promote chemical reactions; also to accelerate the physical changes, such as granular Solute by adding solvent, through the role of mixing machinery can accelerate the dissolution of mixing. The following are the same as the "
Commonly used color mixing machine is divided into gas and low viscosity liquid mixer, medium and high viscosity liquid and paste mixture machinery, thermoplastic material mixer, powder and granular solid material mixing machinery four categories. Gas and low viscosity liquid color mixing machine is characterized by simple structure, and no rotating parts, maintenance and inspection of small, low energy consumption. This kind of mixing machine is divided into four kinds of air mixing, pipeline mixing, jet mixing and forced circulation mixing.
Medium and high viscosity liquid and paste color mixture machinery, generally has a strong shear effect; thermoplastic material mixer is mainly used for thermoplastic materials (such as rubber and plastic) and additives mixed; powder, granular solid material mixing machinery and more For intermittent operation, also includes both the mixing and grinding of machinery, such as wheel rolling machine. Mixing requires all material to participate in the mixed distribution evenly. The degree of mixing is divided into ideal mixing, random mixing and completely unmixed three states. The degree of mixing of the various materials in the mixing machine depends on the proportion of the material to be mixed, the physical state and characteristics, and the type of mixing machine used and the duration of the mixing operation.
Liquid mixing mainly by mechanical agitator, air flow and the liquid to be mixed with the liquid, so that the material to be mixed to be stirred to achieve uniform mixing. Agitation causes some of the liquid to flow, and the liquid is pushed to promote the liquid around it. As a result, a circulating flow is formed in the solvent, and the resulting diffusion between the liquids is called the bulk convection diffusion. When the flow rate of the liquid caused by agitation is high, a shear effect occurs at the interface between the high-speed liquid stream and the surrounding low-speed liquid stream, resulting in a large number of local vortices. These vortices spread rapidly around, and more liquid into the whirlpool, in a small range of the formation of the disorder convection diffusion known as the vortex diffusion.
