[Reason]Improper combination of thickeners, powder settling, and ineffective sterilization.
【Solution】
- Adopting a composite thickening system (such as HEC+ASE) to avoid using a single thickening agent.
- Add anti settling agents (such as gas-phase silica) and regularly stir the inventory paint.
- Strengthen the sterilization system (such as MIT+BIT compound) to prevent spoilage and water separation.
