本发明(专利号:923073523 931005868)是根据操作中把砂布对叠的使用习惯而构思研制的,但对叠后叠层间有搓动位移,能造成砂布提前损坏。本专利双面砂布砂纸提高了使用性能,增大了对叠或卷心使用层间的贴合阻力,力传导性好,操作方便,尤其水砂纸入水使用更得力,磨切工效高,一张双面砂页可顶1.8张单面砂页使用。本产品适用范围广,销量大,若按年产值500万元,班
The present invention (patent number: 923073523 931005868) is conceived and developed based on the habit of using the emery cloth to stack, but there is a turbulent displacement between the laminated stacks, which can cause the emery cloth to be damaged in advance. The patented double-faced abrasive cloth sandpaper improves the use performance, increases the fitting resistance between the layers of the stack or the core, and has good force conductivity and convenient operation. Especially, the water sandpaper is used more effectively in the water, and the grinding and cutting work efficiency is high. Double-sided sand pages can be used with 1.8 single-sided sand pages. This product has a wide range of application and sales, if the annual output value is 5 million yuan, the class
