###### Abstract
[10] observed a substantial enhancement in the surface accuracy of workpiece materials through the use of abrasive water jet technology for polishing brittle and hard materials. [PERSON] et al. [11] conducted jet polishing experiments on hard and brittle materials, achieving a successful reduction in the surface roughness of silicate glass from 2.32 \(\upmu\)m to 0.35 \(\upmu\)m and silicon nitride material from 2.63 \(\upmu\)m to 0.34 \(\upmu\)m. [PERSON] et al. [12] introduced the concept of multi-stage polishing and investigated the impact of various parameter combinations on the surface roughness of BK7 optical glass through experiments. They concluded that employing large abrasive particles for initial-stage polishing and smaller abrasive particles for subsequent stages could more efficiently reduce the surface roughness of the workpiece. The stability of the liquid jet significantly impacts the polishing accuracy of MAWJP. Upon exiting the nozzle, the disruptive influence of air on the jet beam induces a gradual loss of coherence, leading to unstable and unpredictable polishing points. This phenomenon hinders the assurance of surface accuracy during the polishing process for the workpiece [13]. [PERSON] et al. [14] found that, when corundum is used as an abrasive, it can cause severe wear on the focusing tube. This is because, before abrasive particles enter the jet, they reflect multiple times from the outer surface of the jet and the inner surface of the focusing tube, causing various forms of wear of the focusing tube. Moreover, the long-time use of focusing tubes exposed to wear will lead to a loss of precision [15]. Furthermore, the dispersion stability of the polishing solution is influenced by the agglomeration and sedimentation of particles in the liquid, consequently impacting the polishing efficiency and quality [16; 17]. Numerous scholars have undertaken significant studies on the dispersion stability of the polishing solution. [PERSON] et al. [18] investigated the characteristics of the jet before and after the addition of polymers to the abrasive suspension, studying its effect on polishing optical glass. Their experiment revealed a reduced jet dispersion angle after the addition of the polymers, while the surface roughness of the jet-polished area remained consistent. [PERSON] et al. [19] performed process parameter experiments on K9 optical glass, discovering that employing mixed additives resulted in a more uniform surface roughness distribution for the polished workpiece. Additionally, the boundary between the polished and non-polished areas could be reduced. [PERSON] [20] introduced PEO polymers with various molecular weights and concentrations into the polishing solution in order to explore their impact on the width, shape, and centerline roughness of the microchannels. The study indicated that the addition of eight million molecular weight PEO polymers to the polishing solution effectively decreased the width of the microchannels and reduced the centerline roughness, resulting in a V-shape in the cross-section of the processed microchannels. However, an excessive concentration of PEO polymers induced transverse oscillations in the jet. The characteristics of the polishing solution play a crucial role in the jet stability and polishing performance of MAWJP. Therefore, it is essential to formulate a polishing solution with good dispersibility and material removal performance to achieve high surface quality for optical glass. This study initially analyzes the influence of different types and concentrations of dispersants on the dispersibility stability of the polishing solution through static sedimentation experiments. It further investigates the zeta potential and average particle size in the samples after the addition of dispersants, exploring the impact of dispersants on the dispersibility of abrasive particles. The study then utilizes SEM technology to visually discuss the effects of the dispersants at different concentrations.
