Production and function analysis of emulsion

usually emulsification method are mostly will be foreign minister, heated to 80 ℃ ( 75 - 90℃) Around for emulsion, stirring, and then cooling, in the process need to consume large amounts of energy. But theoretically to emulsion does not need so much energy, the emulsifying need energy affects only emulsion dispersion and reduce the surface tension of the caused by surfactant, can calculate the amount of energy needed in theory, it has to do with often emulsification consumed less energy than a lot, that usually emulsification method there is a lot of energy waste, such as heat along with the cooling water are all be discarded. Therefore, J. J。 Lin( Joseph Lin) Low-energy emulsification method is proposed. Its method principle is that in the emulsion, foreign minister not all heating, but the foreign minister is divided into two parts, respectively the alpha and beta facies, alpha and beta alpha beta phase with weight fraction ( The alpha + beta = 1) , heating is carried out on the part of the beta phase, by inside and beta facies in emulsion, made from concentrated emulsion, and then diluted with normal temperature the alpha's foreign minister, finally obtained emulsion. Its principle can be shown by the following figure obviously, the emulsification method saves a lot of energy, energy conservation and efficiency with foreign minister/internal phase and alpha/beta ratio increases. This method not only saves energy, but also can improve the efficiency of the emulsion products, such as shortening the production time, because can greatly shorten the cooling time, and can reduce the use of cooling water to save the energy. The low-energy emulsification method is not only used in the manufacture of emulsion and cream, can also be used in the manufacture of shampoo, but it is mainly suitable for the preparation of O/W emulsion. Low-energy emulsification method described above, it is a basic principle, the practical application, but according to the type of emulsion, the percentage of oil and water phase and its viscosity and other specific requirements, design a feasible low-energy emulsification, the concrete operation process, has an effect on the quality of the emulsion.
