The SK type static mixer is suitable for mixing processes with lower requirements and related unit operations, and can also be used for enhanced heat transfer. Among various models of static mixers, the SK type is the least prone to clogging, making it ideal for handling dirty materials, particularly for high-viscosity media with small flow rates and impurities or viscosity ≤10,600 centipoise. The SK type static mixer has already been successfully used in the following processes: alkali washing desulfurization, industrial naphthalene alkali washing desulfurization, mixing of inks, color pigments in machine oil, cooling of semi-finished emulsion matrices, asphalt removal from residuum using propane as a solvent, and with pulp. Mixing/absorption bleaching of pulp, etc. Common specifications.
