The effect of Oxalic Acid Marble Polish is:
(1) Mechanical grinding action of abrasive particles and plastic deformation action of abrasive particles. The main performance of mechanical grinding is
Impact, shearing and rubbing of slightly convex bodies. Plastic deformation is caused by high temperature and local high pressure at the friction point
W microconvex body produces plastic deformation, making concave and convex parts tend to be flat.
(2) Chemical dissolution and adsorption. The oxalic acid solution dissolved the marble surface and accelerated the polishing process. while
Product calcium oxalate and abrasive in the polymer compound is adsorbed on the marble surface, played a part of the filling effect, increase
Add the smoothness of the board.
(3) Oxalic acid also acts as a corrosion inhibitor to enhance the durability of the surface of the plate.
