How Do You Get The Grit On The Dry Sanding Paper?

The attachment methods of dry sanding paper are similar and can be divided into electrostatic sand planting and gravity sand planting. Electrostatic sand planting relies on electrostatic electric field force to adsorb sand particles to the bottom plate. The distribution of electrostatically implanted sand particles is relatively uniform, but the power of static electricity is limited. If the sand particles are too large, they cannot be sucked, so the electric field force needs to be increased To increase the voltage and current, so the production cost will also increase.

Gravity sand planting is to spread the sand directly from top to bottom without being limited by the size of the sand grains, and the production cost is low. Still, the distribution of the sand grains laid on is uneven, resulting in the sharpness and firmness of the dry sanding paper far inferior to that of the electrostatic and planting. After the sand is implanted, the work has not been completed yet. The sandpaper implanted with the sand has to be sent to the oven. The high temperature will gradually melt the sand into the curing agent, and then apply a layer of resin to fix it. After completion, dry the sand Paper is wound onto rolls and packaged for sale.
