Polyurethane polishing pad filler different,

the addition of fillers (yttria, zirconia) to the polyurethane polishing sheet is a minor addition. the type of filler does not determine the polishing powder used. for example, yttria can be used with a polishing sheet containing a zirconia filler or the opposite is true.

the bismuth oxide-containing polishing sheet-mainly to improve the polishing rate. Zirconium oxide-containing polishing sheet - mainly to improve the finish. Polishing tablets without fillersmainly characterized by stable aperture during polishing.


Polyurethane polishing leather foam hole different role

the polishing foam pores are more favorable to the fluidity of the polishing powder and the polishing rate is better. the less polishing foam pores are stronger in the hydrophilic property, because the polyurethane foam under the eroding of the long-term polishing liquid has more deformation than the polyurethane polishing skin with less foaming holes. Therefore, the foamed holes are more polished. The number of skin repairs increases accordingly.


the advantages of polyurethane polishing skin groove

in order to increase the fluidity of the polishing liquid and increase the polishing rate, a grooved type of polyurethane polishing pad can be used, and generally, a thickness of 1.5 mm or more is selected. the grooved type is respectively 20 mm and 30 mm. the grooved polishing pad will reduce the polishing powder. the larger particles in the lens scratch the lens, mainly for the plane processing.


Advantages of polyurethane polishing skin punching

in order to increase the fluidity of the polishing liquid and improve the polishing efficiency, the type of punched polyurethane polishing leather is used. The size of the general hole is about 2mm. According to the diameter of the lens, the rotation speed of the device, the value of R, the arrangement of the holes is divided into 90 degrees, 60 degrees, 45 degrees, more suitable for spherical processing.


Advantages of polyurethane polishing belt adhesive

the adhesive of polyurethane should be chosen to have good fluidity. If the adhesive layer is uneven, it will cause the unevenness of the polishing surface, which will cause the polished aperture to be unstable. Therefore, the adhesive layer with adhesive can be used to achieve uniform adhesive layer. Polyurethane polishing pads are mostly used for flat surface processing.
