1 disc sand with sandpaper polished processed into round slices, can be divided into two kinds of velvet and double-sided adhesive stickers. For polishing metal parts, plastics, auto parts, when used sandpaper than faster. Newly developed disc sand lubricating properties, wear resistance, heat resistance compared with GC-type graphite cloth greatly improved its overall performance makes GC-type 2-3 times more than the use of the device can be given belt more suburban protection, reducing the frequency of replacement parts, bear much higher work rate and the rural economy rural interests. 2
grinding disc Process description. Workpiece surface profile grinding, difficult. However, the use of a flexible belt can easily process a variety of complex surfaces, the inner radius of curvature of only 3mm fillet, belt can be polished. But for some specific products such as aircraft engines plates, turbine blades, vanes navigation, condenser lamp bowls, mirrors, cutlery, handle, plumbing appliances, etc. are available for efficient high-quality abrasive polishing process.
Sanding methods of dry grinding, wet grinding machine grinding wheel three.
1 Dry sanding: Using sandpaper to polish. For species of hard and brittle paint polish, the drawback procedure will produce a lot of dust, environmental hygiene.
(2) mechanical polishing: large-scale construction, in order to improve work efficiency, can be mechanical polishing methods, such as electric sander (disc, vibration).
3 Wet sanding: sandpaper dipped in water or soapy water and polish. Mill can reduce the wear scar, improve the coating smoothness, and Province sandpaper, and effort. But should pay attention to the water mill underlying paint spray when a layer is completely dry mill to wait before Tu underlying paint, or the paint is easy to whiten. Another highly absorbent substrates should not Watermill.
Grinding process has three main roles:
1, enhanced coating adhesion. Generally required before the new paint sprayed on after hard work sanding old paint layers, paint over smooth surfaces due to poor adhesion, polished coating can enhance mechanical adhesion.
2, the substrate on the substrate surface burr removal, oil dust, etc.;
3, for the putty scraped surface, generally the surface is rough, you need to get through the sand over a flat surface, so sanding the surface roughness can be reduced role.
