How to choose the appropriate emulsifying machine, Germany imported emulsifying machine, industrial emulsifying machine, pilot emulsifying machine
Emulsifying machine plays an important role in industrial equipment mixing system, especially in solid-liquid mixing and liquid
Liquid mixing, oil-water emulsification, dispersion and homogenization, shear grinding have very important applications. The reason
It is called emulsifying machine because it can achieve emulsification. Formed after the complete mixing of oil and water two phase medium
Emulsion can be divided into two systems: oil in water or oil in water. To achieve emulsification, there are at least two requirements:
One is the strong mechanical cutting dispersion effect, the water phase and oil phase of the fluid medium at the same time cut and scattered for small
Particles, and then coalesce when there is mutual infiltration mixing, the formation of emulsion. Two is the right emulsifier,
It acts as a medium bridge between oil and water molecules, and makes oil and water through the action of its electric charge and intermolecular force
The emulsion will be stable for as long as we want.
Now the application of emulsifying machine is not only limited to "emulsification", because of its unique shear action, on
Pulverized particles in the liquid impact eventually refined to the ideal particle size, so that the solid material fully mixed
Into the liquid and form a relatively stable suspension, this process is also known as "dispersion". And of course with emulsification
As with dispersant, the stability of suspension can be enhanced by adding dispersant. When something solid
Can be completely dissolved by the liquid through a certain time of contact with the liquid, then, formed by shear impact
The smaller particles will dissolve faster because their specific surface area is many times larger.
When people are used to high pressure homogenizer (compression, high pressure instant release, jet impact) to obtain
After getting fine particles, "refinement" is equal to "homogenization", so the emulsifier is fine to the material
The process of homogenization and full mixing is also called homogenization. So, we can also put the emulsifier
Called homogenizer, in order to distinguish, generally can be crown in high speed or high shear homogenizer, so that the milk
Chemical machine has many names: high shear emulsification machine, high shear homogenization machine, high shear dispersion emulsification machine, high
Shear homogeneous emulsifier, high shear homogeneous dispersion emulsifier,...
Factors affecting emulsification
1. Emulsifying equipment
At present, there are three main types of emulsifying machine: emulsifying mixer, colloid mill and homogenizer. Emulsifying machine type and structure, performance and the size of the emulsion particles (dispersion) and the quality of the emulsion (stability) has a great relationship. The emulsion produced by agitating emulsifier has poor dispersibility, large and coarse particles, poor stability and easy pollution. But its manufacture is simple, the price is cheap, as long as you pay attention to the reasonable structure of the machine, use properly, but also can produce a general composite quality requirements of the popular cosmetics. Colloid mill and homogenizer are better emulsifying equipment. In recent years, emulsifying machinery has made great progress, such as vacuum emulsifying machine, the dispersion and stability of the emulsion prepared by it is very good.
2, the temperature
Emulsification temperature has a great influence on the quality of emulsification, but there is no strict limit on the temperature. Generally speaking, during emulsification, the temperature of oil and water phases can be controlled between 75℃ and 85℃. This depends on factors such as the melting point of substances with high melting point, the type of emulsifier and solubility of oil phase and water phase.
3. Emulsifying time
Emulsification time has an effect on the quality of emulsion. The length of emulsifying time is related to the volume ratio of oil phase and water phase, the viscosity of two phases and the viscosity of the generated emulsion, the type and dosage of emulsifier, emulsifying temperature, emulsifier type and other factors. It is usually determined by experience and experiment.
4, mixing speed
Mixing speed must be adequate
