Coated sand. The surface of the sand is covered with a layer of solid resin film before molding. There are two coating processes: cold method and hot method. The cold method is to dissolve the resin with ethanol and add urotropine during the sand mixing process so that the two are coated on the surface of the sand. The ethanol evaporates to obtain coated sand. The hot method is to preheat the sand to a certain temperature, add the resin to melt it, stir it to coat the resin on the surface of the sand, add urotropine aqueous solution and lubricant, cool, crush and screen to obtain coated sand. It is used for steel castings and iron castings.
