Jiangsu union SX static mixer unit consists of many X-type units composed of cross bars according to certain rules, and the degree of mixing unevenness is s x ≤ 1-5% Product use: SX static mixer is suitable for medium and high viscosity liquid-liquid reaction, mixing and absorption process with viscosity ≤ 104 centipoise, or mixing and reaction process for production of high polymer fluid, with better effect when the treatment capacity is large. Application fields: It is suitable for chemical, petroleum, pharmaceutical, food, fine chemical, plastic processing, environmental protection, synthetic fiber, mining and other fields. Application example: SX static mixer is applied in the light ketone benzol dewaxing oil unit of a unit, which can reduce the wax oil content, reduce the phenomenon of wax deposition in the pipeline and easy blockage of the feed pipeline of the filter, solve the problem of solvent leakage in the mixing seal, purify the environment and save energy.
