The polishing pad is used for polishing the surface of the workpiece and the plating layer. The polishing wheel is divided into: polishing cloth wheel, hemp wheel, nylon wheel, wiring wheel, wind wheel, wool wheel, etc. There are many types.
What are the functions of common polishing pads on the market?
What are the characteristics and functions of the lint-free polishing pad with pile structure?
What is the use process of polishing pad?
1 Polyurethane polishing pad, whose main component is foamed solid polyurethane, has many spherical microporous cell structures on its surface, which can collect, process and remove, transmit polishing liquid and ensure chemical corrosion. It is beneficial to improve the efficiency of polishing and the uniformity of polishing. The larger the hole size on the surface, the greater the transport capacity. But it will affect the density and stiffness when polishing. Moreover, this type of polishing pad has good wear resistance and is generally used for rough polishing.
2. Non-woven polishing pad, because the polymer is cotton fiber, so the water permeability is very good. This kind of polishing pad can make the polishing liquid penetrate into the interior of the polishing pad, and can fully ensure the uniformity of the polishing liquid. Generally used in fine polishing process.
The cloth-free polishing pad with fluff structure is mainly composed of non-woven fabrics, and the middle is polymer, and the surface layer is a porous fluff structure. Its main features are: small hardness, large compression ratio and good elasticity; when the polishing pad is under pressure, it will suck the polishing liquid into the cavity like a sponge, and when the force is released, the old polishing liquid and chemical reactants will be discharged and discharged. Supplement with new polishing liquid to obtain a good polishing effect, which is generally used in the fine polishing process.
The polishing process refers to polishing the disc with a low-elastic material (cotton, felt, artificial leather, etc.) rotating at a high speed, or using a soft elastic or viscoelastic material (plastic, asphalt, paraffin, tin, etc.) rotating at a low speed. Agent, a processing method with certain abrasive properties to obtain a smooth surface. In short, there is no essential difference between grinding and polishing, except for the choice of abrasive and lap materials. Polishing generally cannot improve the shape accuracy and dimensional accuracy of the workpiece. Polishing usually uses fine abrasive particles below 1µm. polishing pads are usually made of asphalt, paraffin, synthetic resin, artificial leather, tin and other soft metal or non-metal materials. The abrasive has a small force on the workpiece and cannot cause cracks in the workpiece. . It is customary to call the processing method using a hard grinding tool grinding, and the method using a soft grinding tool is called polishing.
Hubei Little Ant Diamond Tools CO., Ltd Has worked on the production of polishing pads for over ten years. You can find the best polishing pad in this company.
