AI Technical Summary
Technical Problem
The prior art has shortcomings in suppressing powder settlement, especially when using thickeners with high permeability, it is still difficult for the powder to effectively suppress settlement after a long period of use.
Method used
The combination formed can effectively inhibit the precipitation of the powder by combining specific water-soluble polymers (Acrylates/Alkyl Acrylate (C10-30)) Crosspolymer and 'anionic surfactants' and controlling the average particle size of the powder to a range of 0.05-500 μm.
Benefits of technology
The excellent settlement suppression effect of the powder is achieved, thereby improving the stability of the combination and maintaining good stability under low-temperature storage conditions.
