How to dissolve polyvinyl alcohol PVA



The dissolution of polyvinyl alcohol PVA is a delicate process, and whether the dissolution is good or not may have an impact on subsequent production steps and product quality.

1. Disperse polyvinyl alcohol PVA in cold water to prevent it from sticking together.

2. During production, a bulk cone can be placed at the feeding inlet to control the speed of polyvinyl alcohol PVA addition.

3. After adding polyvinyl alcohol PVA, it should be left in a stationary state for a period of time to allow polyvinyl alcohol PVA to swell in water for a while, and the swelling time should be controlled.

(Depending on the model, the swelling time varies for different models)
