Factors affecting emulsification and factors affecting emulsification from a device perspective!
There are several factors that affect emulsification:
1. Process formula. Different processes and formulations have a very large effect on the emulsification of silicone oil. It determines the proportion of raw materials in the preparation process and the order of addition.
2. Emulsifier. Different emulsifiers change the structure of the product and the effects on the interfacial tension and the energy required to form the emulsion are also different.
3. Emulsifying equipment. Different emulsification equipments have different structural designs, different shearing forces and rotational speeds, which greatly affect the emulsification effect.
Analysis of factors affecting the dispersion emulsification effect from the perspective of equipment
1. The structure of the emulsifier. The emulsifier is generally divided into a batch emulsifier and a pipeline emulsifier. The pipeline emulsifier has better emulsification effect, and the material can be fully dispersed and emulsified, and the efficiency is high. The IKN high shear emulsifier uses a line-type emulsification method.
2. Shearing rate of the emulsifier. The core parameter of the emulsification equipment is the shear rate. Under normal circumstances, the higher the shear rate, the better the dispersion emulsification effect, of course, it needs to be determined according to the specific material process; the IKN emulsifier is accelerated by the belt, and the rotation speed is as low as 9000 rpm, which is domestic emulsification. It is 3 times the speed of the machine and the maximum speed is 21,000 rpm.
3. Processing time. The longer the material stays in the cavity, the better the dispersion emulsification effect, and the more the number of treatments, the better the dispersion emulsification effect. The structure design of the IKN emulsifier adopts a vertical split structure with short running time.
4, the precision of the emulsification head. The traditional emulsifier adopts a single-layer emulsification head for rough processing, while the IKN nano-mass emulsifier uses a three-stage emulsification head with smaller gap, higher precision and better emulsification effect.
Equipment selection points:
1. Defining the effect and purpose of using the equipment
2. Learn and master the properties of the research materials (including physical and chemical properties)
3, according to the material to the equipment mixer selection
4. Determine the operating parameters and structural design of the equipment again.
5, comprehensive consideration of the cost of equipment
The main products of basic chemical industry, such as hydrochloric acid, caustic soda, soda ash, ammonium chloride and chlorine gas, are mainly produced with industrial salt as raw materials. In addition, also used in soap manufacturing, ceramic, glass production, daily chemical, oil drilling, drilling fluid, completion fluid, petrochemical dehydrated liquid, early strength agent, construction industry in the production of coating latex coagulation agent, curing agent, rubber industry papermaking additives and waste paper deinking, chemical industry of inorganic chemical raw materials and sulfuric acid root removal agent, the curing agent of alginic acid sodium, the prevention and treatment of wheat, apple, cabbage, such as decay and preparing food preservatives, metallic sodium and other sodium compounds, such as steel heat treatment medium. Salt is also widely used in water treatment, road snow removal, refrigeration and refrigeration.
