Product Features
The unit is welded by single-channel left and right twisted spiral pieces. Its technical performance; the highest degree of dispersion ≤ 10 μm, the liquid-liquid, liquid-solid phase unevenness coefficient α X ≤ 5%.
The pressure drop calculation of the product is expressed by the friction coefficient ΦD based on the equivalent diameter of the mixer and the inner diameter D.

Product Usage
Suitable for chemicals, petroleum, pharmaceuticals, food, fine chemicals, plastics, environmental protection, synthetic fibers, mining
The processes of mixing, reaction, extraction, absorption, injection molding, color matching, and heat transfer in metallurgy and other departments are especially suitable for high-viscosity media with small flow and impurities or viscosity ≤ 106 centipoise.
Applications
● Application of SK static mixer in the device for removing asphalt from residual oil with propane as solvent
The propane deasphalting unit of a domestic plant uses vacuum residue as raw material and liquid-phase propane as the solvent to perform liquid-liquid extraction to produce high-viscosity lubricating oil into catalytic cracking raw materials. At the same time, asphalt is obtained, which achieves good residue dilution and improves The oil recovery rate is reduced, the solvent ratio is reduced, and energy consumption is saved.
● Application of SK static mixer in pulp chlorination process
A domestic paper mill used the SK static mixer produced by Silpu Company. The amount of chlorine management meets the technological requirements and guarantees the quality of the bleached pulp. Because the chlorine is fully dispersed, reacted and absorbed in the pulp, the production is normal and there is no overflow. The chlorine phenomenon improves the production environment and increases the rate of high-quality slurry.
