As the most common grinding tool, Abrasive paper is mainly polished by thousands of abrasives on the surface. Do you know how the sand on the sandpaper is fixed? Let's take a look at the manufacturing process of sandpaper.
The manufactured reel abrasive paper substrate is opened on the machine. The substrate used for the sandpaper is cloth, paper and composite substrate. After the abrasive cloth substrate enters the machine and passes between two rollers, the specifications, size, trademark and other information will be printed on the back of the abrasive cloth.
The rubber roller with printing function prints the cured adhesive at the same time. At this time, the computer will measure the density of the sand cloth coating to achieve the best curing effect of the adhesive, and then electrostatically treat the adhesive cloth with the adhesive. It is sent to the electrostatic chamber.
