Masterbatch dispersion scheme

Masterbatch dispersion is a technique in which solid or liquid particles are dispersed in a solution to obtain a high-quality, uniform solution. This technology is widely used in many fields such as chemistry, medicine and biological sciences. This paper introduces the principle, experimental procedure and precautions of masterbatch dispersion scheme.

Principle of masterbatch dispersion scheme

The principle of masterbatch dispersion is to use cross-linked polymers or surfactants to disperse the particles in water or organic solvents, and then through high-speed stirring or ultrasonic treatment, the solid or liquid particles are evenly dispersed in the whole solution. The purpose of masterbatch dispersion is to eliminate the aggregation between particles to improve the stability and uniformity of the solution.

Experimental procedure of masterbatch dispersion scheme

1. Preparation of mother liquor: mother liquor is generally selected as water or organic solvent. If an organic solvent is used, ensure that it is not corrosive to particles.

2. Add crosslinked polymer or surfactant: According to the desired particle dispersion degree and type, select the appropriate crosslinked polymer or surfactant and add it to the mother liquor. The surfactants usually used are Tween 20 or Tween 80, and the crosslinked polymers used are polyacrylamide, polyacrylic acid, etc.

3. Add particles: Add the required particles into the mother liquor, and let them disperse evenly under the condition of low speed stirring.

4. High-speed stirring or ultrasonic treatment: In the case of ensuring the uniform dispersion of particles, high-speed stirring or ultrasonic treatment is carried out to further disperse the particles in the whole solution.

5. Filtration: In order to remove impurities in the particles, the mother liquor is filtered to obtain a uniform solution.

Considerations for masterbatch dispersion scheme

1. Select appropriate crosslinked polymers or surfactants, and do not use solvents that have corrosive effects on particles.

2. Ensure the uniformity of the particle addition, and the z is better to be completed under the condition of low speed mixing.

3. When stirring or ultrasonic treatment, it should be ensured that the particles will not accumulate, resulting in uneven dispersion.

4. Confirm that when the mother liquor is filtered, the aperture of the filter should be selected according to the particle size to maintain the uniformity of dispersion.

5. Pay attention to the quality of cleaning experimental equipment and cleaning liquid to prevent secondary pollution from impurities.

conclusion

Masterbatch dispersion scheme is one of the important methods to disperse particles, which can obtain high quality and uniform solution, and is widely used in chemistry, medicine and biological science. During the experiment, precautions are very important, and the operator should strictly follow the experimental steps to obtain satisfactory results.
