What specific effects does the increased friction of the Triangular Foam Polishing Pad have on the polishing effect?

In the polishing operation, when an ordinary foam polishing pad is used and the polishing pressure is low, the contact between the wafer and the polishing pad is relatively loose and the friction is low. At this time, the mechanical scraping and grinding effect of the polishing pad on the workpiece surface is very weak, resulting in a small amount of material removed per unit time and an extremely low material removal rate. The unique bottom shape design of the Triangular Foam Polishing Pad enables it to generate greater friction when in contact with the workpiece surface. This increased friction significantly enhances the mechanical effect of the polishing pad on the workpiece surface under the same polishing pressure. The foam particles on the surface of the polishing pad can more effectively scrape the raised parts of the workpiece surface and accelerate the stripping and removal of materials. For example, when polishing the paint surface of a car, the Triangular Foam Polishing Pad can remove the paint oxide layer and minor scratches faster, improving the efficiency of the polishing operation.
The polishing process is not only the result of mechanical action, but the chemical action of the polishing liquid also plays an important role. The polishing liquid usually contains some components that can react chemically with the workpiece surface material, which can soften or decompose the substances on the workpiece surface, making it easier to remove. When the Triangular Foam Polishing Pad increases friction, it can promote the uniform distribution and full penetration of the polishing liquid on the workpiece surface. Friction makes the relative movement between the polishing pad and the workpiece surface more intense, and the polishing liquid is more easily brought into the microscopic depressions and gaps on the workpiece surface, fully contacting and reacting chemically with the workpiece surface material. At the same time, the heat generated by mechanical friction can also accelerate the rate of chemical reactions. For example, in metal polishing, the acidic components in the polishing liquid can react with the oxides on the metal surface, and the increased friction helps this reaction to proceed, allowing the metal surface to restore its brightness faster.
Polishing uniformity is one of the important indicators for measuring polishing quality. If the polishing is uneven, the surface of the workpiece will have problems such as inconsistent local gloss and color differences, affecting the overall aesthetics. The special shape and increased friction of the Triangular Foam Polishing Pad help solve this problem. Its bottom shape allows the polishing pad to contact the workpiece surface more evenly during the polishing process, avoiding the situation where the local pressure is too large or too small. During the polishing process, all parts of the polishing pad can function evenly, reducing the phenomenon of excessive or insufficient removal due to insufficient local contact. For example, when polishing a large area of ​​a car body, the Triangular Foam Polishing Pad can better adapt to the curved shape of the car body, making the polishing effect of the entire car body surface more uniform.
Scratches can seriously affect the quality of the workpiece surface. Scratches are usually caused by the uneven relative movement between the polishing pad and the workpiece surface, or the presence of hard particles on the polishing pad surface. The increased friction of the Triangular Foam Polishing Pad can make the polishing pad contact the workpiece surface more smoothly during the polishing process. Appropriate friction can reduce the sliding and jumping between the polishing pad and the workpiece surface, and reduce the risk of scratches caused by uneven relative movement. At the same time, the Triangular Foam Polishing Pad is usually made of soft foam material, and its surface is relatively smooth, which reduces the scratches on the workpiece surface by hard particles. For example, when polishing precision metal parts, the use of Triangular Foam Polishing Pads can effectively reduce surface scratches and improve the surface quality of parts.
The increased friction of the Triangular Foam Polishing Pad also interacts with its surface structural characteristics to jointly affect the polishing effect. Reasonable groove design can improve the ability of the polishing pad to store and transport polishing fluid. The grooves deliver the polishing liquid to the contact area between the polishing pad and the workpiece surface, ensuring a continuous supply of the polishing liquid. At the same time, the grooves can also improve the fluidity of the polishing liquid, allowing the polishing liquid to be more evenly distributed on the workpiece surface.
