Goldphase sandpaper is specially used for polishing metallographic analysis sample sandpaper,the general gold phase sandpaper is similar to ordinary sandpaper.According to the characteristics of metallographic proofing,metallographic special sandpaper includes formed metallographic sandpaper and formed metallographic water sandpaper,with a diameter of 230mm and 200mm circular sheet specifications,specially used for coarse grinding and fine grinding of metallographic proofing.Suitable for various domestic and foreign models and specifications of gold pregrinder,especially suitable for all kinds of semi-automatic or automatic gold grinding machine.

　　The sandpaper used in the process of polishing shall be water-resistant sandpaper and sand belt.Water-resistant sandpaper and sand belt is a water-resistant abrasive made of artificial or natural abrasive bonded on the surface of water-resistant paper.The abrasive coated on the water-resistant sandpaper is corundum or silicon carbide.The fine sandpaper used for metallography is generally silicon carbide.

　　Alographic special sandpaper with selected,uniform particle size,excellent grinding effect of silicon carbide grinding grain as abrasive,metallographic special water resistant sandpaper made by electrostatic sand planting process,has the characteristics of uniform grinding distribution,sharp grinding,durable.Thus,the grinding speed of the sample is fast,the deformation layer is shallow,and the effect on high hard or hard materials is particularly obvious.All rough grinding and fine grinding processes can realize water grinding,which completely eliminates the disadvantages of sample grinding and dust.Because gold phase sandpaper has many excellent tables,it is often used in mold processing(polishing)and other high finish processing.

　　The use of gold-phase sandpaper

　　For sandpaper for metallographic analysis,the classification of sandpaper has dry grinding and water resistance,ordinary binder and resin binder,brown corundum,white corundum,silicon carbide,zirconium corundum and other abrasives.Alographic special sandpaper with selected,uniform particle size,excellent grinding effect of silicon carbide grinding grain as abrasive,metallographic special water resistant sandpaper made by electrostatic sand planting process,has the characteristics of uniform grinding distribution,sharp grinding,durable.Gold sandpaper refers to those very fine number can be used for polishing sandpaper,these sandpaper can be used to level the surface of the block,after leveling the surface can be through the gold microscope to see the block or other equipment,so it is also called"gold sandpaper".
