Polyvinyl Alcohol Wetting Agent Mixing to Suppress Aggregates

The patent applies preliminary action by dispersing polyvinyl alcohol particles in water before heating, creating a pre-dispersed state that prevents aggregate formation during subsequent dissolution. The dispersion step prepares the system in advance so that when heating occurs, particles are already separated and can dissolve uniformly without coalescing into aggregates.

The patent applies parameter changes by controlling the temperature and addition rate when mixing aqueous polyvinyl alcohol solution with other aqueous solutions. By maintaining appropriate temperature parameters and controlling the rate of mixing, the patent prevents aggregate formation while still allowing versatile applications. The parameters of temperature, concentration, and mixing speed are adjusted to maintain solution stability during combination with other solutions.

The patent applies preliminary anti-action by preventing aggregate formation in the first place through proper dispersion and controlled heating processes. By taking preventive measures during the dissolution and mixing stages, the patent eliminates the need for extensive filtration later, thereby maintaining high product purity while avoiding productivity loss from time-consuming filtration operations.
