How hair stone coating processing? ？ ？ ？ ？

Stone lacquer coarsening is to use sand paper or sanding machine to surface treatment, surface coating weight according to actual situation. Most of which are within the prescribed time interval, not coated by a layer of stone coating or coating surface pollution to a certain extent, affect coating adhesion when the remedial measures. Rough stone paint effect: in the case of stone paint surface is exposed to the air, long formation on the surface of a layer of pulverization layer. Through the roughness, can remove and dirt on the surface of the pulverization layer. By roughness, can increase the paint on the surface of the 'roughness', provide greater contact surface for subsequent coating, so as to ensure good coating binding force. Security: a stone like a nap in theory does not produce sparks. When you see it, you'll hit bottom. In fact, should consider to the workers of the film thickness and the complexity of technology and structure. The highest security and controllability of artificial nap. But the cost and time limit for a project is greatly increased.
