Electrostatic sand planting and gravity sand planting
Electrostatic planting sand belt is the use of high voltage electrostatic adsorption principle, so that the abrasive polarization absorption, and according to its own direction of the long axis embedded in the rubber layer on the surface of the substrate, so as to form a neatly arranged, evenly distributed abrasive layer. The grinding efficiency of electrostatic planting sand belt is more than 25% higher than that of general gravity planting sand belt.The surface roughness is even and good.The density of electrostatic planting sand is also easy to control.
Gravitation plant sand (also known as mechanical plant sand) sand belt is the use of abrasive self-weight, from a certain height of free fall and embedded in the rubber layer on the surface of the substrate, in order to form the abrasive layer, with this method of planting sand, abrasive distribution direction is variable, mostly for the "lodging" state.The sharpness of the cutting edge of the abrasive belt is poor, so the grinding efficiency and surface quality are not as good as those of electrostatic sand planting belt.Controlling the density of plant sand is also more difficult.
