In the field of chemical production, sodium hydroxide (NaOH) is a highly corrosive white crystal that is highly soluble in water and releases a large amount of heat. Due to its excellent alkaline properties, it is widely used in papermaking, textile, petrochemical, and sewage treatment industries. As an important chemical raw material, the scientificity and safety of its mixing process directly affect the product quality. The three-dimensional mixer, with its unique spatial movement trajectory, provides an efficient solution for the mixing of sodium hydroxide.

The three-dimensional mixer achieves material mixing through the compound movement of the cylinder in three-dimensional space. When the cylinder moves circumferentially, radially and axially, sodium hydroxide particles undergo translational, tumbling and convective movements under the action of inertial force and gravity. This multi-dimensional movement breaks the traditional mixing limitations and enables the particles to be uniformly distributed in the cross paths. Actual production data shows that when this equipment mixes sodium hydroxide, the uniformity can reach over 99.5%, which is 40% more efficient than traditional mixers.

However, given the strong corrosiveness of sodium hydroxide, the process parameters during the mixing process must be strictly controlled. The inner wall of the three-dimensional mixer should be made of 316L stainless steel and supplemented with Teflon coating passivation treatment to prevent direct contact between the metal and the materials. The mixing temperature should be controlled at 30-50℃ to prevent moisture absorption and caking due to excessively high temperatures or affecting fluidity due to excessively low temperatures. In terms of safety operation, a negative pressure dust removal system should be equipped to prevent dust from spreading, and operators must wear acid and alkali resistant protective equipment.

At present, the application of three-dimensional mixers in sodium hydroxide mixing is moving towards intelligence. This process, which integrates high efficiency, safety and intelligence, not only ensures the quality of sodium hydroxide related products, but also sets a model for technological innovation in the field of chemical mixing.
