The polishing solution is prepared to polish the glass, and the principle is that the glass to be polished is put into the prepared chemical polishing solution, so that the microscopically convex part of the glass in the chemical medium is dissolved preferentially than the concave part to obtain a smooth surface, or the glass sheet is soaked into strong corrosive acid solution or alkali solution, the glass surface is subjected to chemical reaction, and the glass surface is continuously etched until the glass surface has the frosted appearance effect.

When glass is subjected to liquid polishing treatment, the glass is usually subjected to liquid polishing in a liquid polishing tank. As shown in fig. 1, a conventional liquid throwing tank 21 is generally provided with a perforated stainless steel plate 22 at the bottom, and a circulation nozzle (not shown) and a bubbling pipe (not shown) are provided below the perforated stainless steel plate 22. In use, glass is placed on the support (23, 24, 25, 26), polishing solution from outside enters the liquid throwing groove through the circulating spray pipe, and under the cooperation of the bubbling pipe, the polishing solution is formed through a plurality of holes on the porous stainless steel plate 22 to soak the glass on the support according to the wave rule. Because the polishing solution is wavy, when the immersed glass is polished up and down and left and right, the problem of uneven stress on four sides exists, so that polished products generate contact position polishing marks, and the product qualification rate is reduced.

Based on this, a new solution is needed.
