The principle of high shear emulsifier is to complete emulsification, dispersive grinding, homogenization and mixing by the relative high-speed movement of the rotor stator. The principle is that under the strong shear force produced by high-speed rotation, the products that need to be mixed will be crushed and emulsified, which can be used for continuous emulsification or dispersion of multiphase liquid media, and also for the transport of low-viscosity liquid media. It can also realize continuous mixing of powder and liquid in proportion. It is widely used in daily chemical, food, medicine, and chemical industry. Industry, petroleum, coatings, nanomaterials and other fields. But how much grinding fineness can emulsifiers achieve? This should be discussed from the following aspects: material characteristics, hardness, toughness, concentration, particle size of the material itself.
Generally speaking, if the toughness is too high, the fineness of high shear emulsifier should be more than 100 microns, such as carbon fibers.
If the hardness of the material is too high, the grinding effect is not very good. For example, latex paint in the grinding mixing stage contains titanium dioxide and other harder media, then the grinding fineness of the emulsifier may be the size and size of the titanium dioxide itself in a certain working time. The final fineness of latex paint is about 50 microns.
Therefore, simply requiring the fineness of the material after emulsification and grinding is unable to get the exact answer, and do not blindly listen to the promises that some manufacturers have not based on.
