Analysis of the speed problem of emulsifier

The emulsifier has the main effects in the industrial equipment mixing system, especially in the solid-liquid inclusion, liquid-liquid inclusion, oil-water emulsification, sputum homogenization, shear grinding and other extremely important use. The reason why it is called an emulsifier is that it can achieve the effect of emulsification. The oil-water two-phase medium is completely mixed to form an emulsion, which is divided into two systems: water-in-oil or oil-in-water. To complete the emulsification, there are at least two requirements: First, the intense mechanical cutting and dispersing effect, the water phase and the oil phase The fluid medium is also cut and broken into small particles, and then merged and merged to form an emulsion. The second is a suitable emulsifier, which serves as the bridge between the oil and water molecules. Through the effect of its charge and intermolecular force, the oil-water inclusion emulsion can be stored according to the time we need.

At present, the use of the emulsifier is not limited to "emulsification", because its common shearing effect, the crushing of the powder in the liquid destroys the impact and finally refines to the fanciful particle size, and then the solid is fully blended into the liquid. Medium and constitute a relatively constant suspension. Of course, as with the emulsifier, the invariance of the suspension can be enhanced by the addition of a sizing agent. When a solid substance is completely ablated by the liquid through inevitable contact with the liquid, the small particles formed by the shearing impact will be ablated faster by the liquid, which is many times larger than the outer surface. When people are accustomed to obtaining fine particles through a high-pressure homogenizer, the refinement is equal to the homogenization. Therefore, the effect of the emulsifier on the refinement and full blending of the material is the homogenization process. Therefore, we can also refer to the emulsifier as a homogenizer. For easy distinction, it can be crowned at high speed or high shear homogenizer, so that there are many different methods for emulsifier: vacuum homogenizer, high shear Homogenizer, high shear homogenizer, high shear homogenizer, aseptic homogenizer, high shear homogenizer, vacuum homogenizer, pipeline homogenizer, etc.

The strength of the shearing effect of the emulsifier directly affects the final fineness. Through analysis, it is mainly related to the sharp level of the blade, the hardness, the stator gap, the relative movement speed of the two cutting edges and the particle size of the cut. Under the condition, the blade sharpness level, hardness, stator gap and the diameter of the promised passage have been fixed or not changed. The relative movement speed of the edge of the emulsifier is the most influential factor, which is shown as the circumferential linear velocity of the rotor. The high linear velocity results in a high density of cutting or impacting of the radially moving fluid, so that the refining effect of the emulsifier is strong, and vice versa.

However, the linear speed of the emulsifier is not as large as possible. When it reaches a very high value, there is a tendency to constitute obstructive activity, so the fluid becomes very small, and the fever is high, and some materials are in turn aggregated, so that the consequences are not Delusion. From another point of view, the characteristics of the experiment in the implementation room are small. Therefore, if the physical size of the tempering machine's rotating stator is to comply with a small number, the diameter must be small. In order to compensate for the negative impact of the small diameter on the line speed, it must be To improve the angular velocity of the rotor, the "high speed" of the instrument is constructed.

It can be seen from the above that the speed of the emulsifier is to be considered in combination with the actual amount of disposal. However, it is based on the existing processing level and economical production. The speed of 18.5KW is usually 3000rpm for 2-pole motor, and 22KW to 55KW. For a 1500 rpm for a 4-pole motor, you can think of a 1000 rpm for a 6-pole motor beyond 75 kW.

Suggestion: The purchase of emulsifier should try to choose a company with reputation and rich experience. For example, there is packaging in Nanjing Shunliu. The quality of vacuum homogenizing emulsifier is reliable, the workmanship is precise, the material is covered, and the key parts are protected by wear resistance. Secret design, good exchangeability, low maintenance cost, long life, good service, and universal influence in the industry.
