What are the ways to remove the black spots on the surface of polyurethane casters?

Update:2022-09-26

The purification solvent is to use the oxide added to the industrial castor fluid to be wetly absorbed and dissolved by these droplets, forming new droplets to rise to the surface, and to form scum to be removed after cooling. The flux used for purification of industrial casters is composed of salts with low melting point, low density, small surface tension, high activity, and strong adsorption capacity for industrial polyurethane caster slag. Non-metallic inclusions and dissolved hydrogen are removed, followed by continuous elimination, so that fine nitrogen bubbles are evenly distributed in the treated purification liquid for purification.
