emulsion viscosity
Thread Content
What is the relationship between the viscosity of the emulsion and the particle size? There is also the specific gravity of the emulsion. I don’t know what is the connection between them? Please give me some advice from relevant personnel.
The viscosity of the emulsion is mainly caused by the characteristics of the composition. Of course, the smaller the particle size of the molecules, the smaller the viscosity.
For emulsions, the smaller the particle size, the smaller the viscosity? It should be that the larger the particle size, the worse the dispersion and the lower the viscosity.
Generally speaking, the smaller the particles of the emulsion, the greater the viscosity. Because the smaller the particles, the larger the surface area and the greater the surface friction during flow. In addition, small particles tend to have large electrical loads, and their inter-particle forces are also large. So the smaller the particles, the greater the viscosity. In addition, the viscosity of the emulsion can be adjusted to a large extent by adding electrolytes or thickeners, etc.
The viscosity and solid content of the emulsion produced by our company are adjusted by adding DMW (desalted water).
Generally speaking, the greater the molecular weight, the greater the viscosity, and its viscosity is also related to the solid content.
The viscosity of the emulsion is also related to the stirring type. Increasing stirring: lol Strength and shear force can increase the viscosity of the emulsion, but in the end it is a problem of particle size. Small particle size and large viscosity
The smaller the particle size, the greater the viscosity and the smaller the solid content. The greater the viscosity, the viscosity of the emulsion is sometimes related to the monomer used. That is to say, with the same solid content and the same process conditions, the viscosity will be significantly different if a certain monomer is replaced. In addition, the viscosity of seed emulsion polymerization is sometimes related to the amount of seed emulsion.
The viscosity of the emulsion is related to the properties of the generated material. The smaller the particle size, the greater the viscosity. The smaller the solid content, the greater the viscosity, which is related to the monomer and the dispersion effect.
The viscosity of lotion is also related to its pH value
PH has a greater impact on viscosity because the hydrophilic groups it contains ionize and repel each other, increasing viscosity. The higher the solid content, the greater the viscosity, which is also related to the particle size distribution. The smaller the particle size, the higher the viscosity.
It has the greatest relationship with pH value and solid content.
It is related to particle size, solid content, and pH value will also affect its viscosity.
The viscosity of the emulsion is related to factors such as the viscosity of the external phase, the viscosity of the internal phase, the volume fraction of the internal phase, the size of the droplets, and the properties of the emulsifier.
It should be that the smaller the particle size, the greater the viscosity, because the smaller the particle size, the greater the friction per unit area.
The viscosity of the emulsion is related to the particle size of the dispersed particles, solid content, dispersant, etc. Generally, the smaller the particle size, the greater the viscosity! This 4th floor said it very clearly! Answer from Floor 7: If the emulsion is a shear-thinning fluid, as the stirring rate increases, the viscosity will decrease and on the contrary increase!
