1. Combined with Zeta potential, sedimentation experiment, viscosity measurement and other methods, the influence of various dispersants on CEO and slurry suspension effect was studied.

The results showed that the formula with good stability was the appropriate concentration of mixed dispersant (NAP +SBN) or (NAP +PAM+SBN).gold adsorption on activated carbon 

2. The removal rate of CEOZ slurry prepared with mixed dispersant (NAP +PAM+SBN) in the processing of K9 glass by MASJP was higher than that of other mixed dispersants.www.chinactivecarbon.com  

By comparing the processing effect of MASJP with and without mixed additives, it is found that the processing effect of MASJP with mixed additives (NAP +PAM+SBN) has higher surface quality, which can significantly reduce the interface area between the polished area and the unpolished surface and increase the smooth surface as much as possible.3. Combining online observation and single factor method, the formation process of the surface features of the polished area was studied. The experimental results showed that the surface morphology of the polished area showed a W-shaped bowl structure in the vertical jet machining, and an eccentric bowl structure in the crescent shape in the oblique jet machining.Compared with the abrasive water jet machining effect, it is found that the W shape and crescent shape characteristics of the polishing region of MASJP are relatively flat, the smooth surface is larger and the surface quality is higher.

4. When applying nozzle with different outlet shapes in MASJP, it is found that the fluid ejected from the cylindrical nozzle flows out along the direction of the jet and does not disperse.

The processing area of the fan-shaped nozzle is large, the polishing area is approximately a rectangle, and the removal depth near the nozzle is larger.Hollow conical nozzle processing finished parts, the polishing area formed a hollow circle, the central part of the removal of less, the circumference of the removal of deep;The removal depth of the polishing area decreases gradually from the center to the circumference after the finished piece is processed by the solid conical nozzle.

5, the workpiece surface profile and material removal depth with the selection of polishing slurry composition changes.With the increase of abrasive concentration, the material removal depth increases, which is roughly in a proportional relationship.With the increase of abrasive particle size, the material removal depth also increases.
