Static mixer is an advanced mixer developed in the early 1970s. 1970, the static mixer developed by Kenis Company of the United States was first introduced. Since 1980s, domestic related enterprises have also invested in research and production, which has been well applied in the production of emulsified fuel.

Since 1970s, static mixers have been applied in chemical industry, food industry, textile industry and other industries, and achieved good results. However, as a patented product, the static mixer is not only kept secret at home and abroad, but also made into a disposable structure. At the same time, the viscosity of curing agent and epoxy resin is very different (the viscosity of epoxy resin is 20 ~ 80 times that of curing agent), and the flow velocity of the two fluids in the pipeline is very low, so it is difficult to mix them evenly.

Static mixer is an advanced unit equipment. Different from the agitator, it has no moving parts inside, and mainly uses fluid flow and internal units to achieve complete mixing of various fluids and special design rationality. Compared with other equipment such as orifice tower, venturi tube, agitator and homogenizer, static mixer has the advantages of high efficiency, low energy consumption, small size, low investment and easy continuous production. In the static mixer, the movement of fluid follows the law of "diversion-displacement-overlap", and displacement plays a major role in the mixing process. Displacement modes can be divided into two categories: "relative displacement caused by velocity distribution in the same section" and "multi-channel relative displacement", and the displacement modes of different types of mixers are also different. The static mixer of Haitai Maxim can be used not only in the mixing process, but also in the processes related to mixing-transfer, including gas/gas mixing, liquid/liquid extraction, gas/liquid reaction, enhanced heat transfer and liquid/liquid reaction. Static mixers are widely used in plastics, chemical industry, medicine, mining and metallurgy, food, daily chemicals, pesticides, cables, petroleum, paper making, chemical fiber, biology, environmental protection and other industries. The product has the advantages of low energy consumption, low investment, good effect and quick response, which brings considerable economic benefits to users.
