Colored sand in the Caisha Epoxy Floor refers to colored quartz sand instead of other types of sand. The reason why quartz sand was chosen is because of the wide source of quartz raw materials and the high hardness of minerals, which has provided a fundamental guarantee for the raw materials and quality of floors. Quartz sand is colorless or white. Through the new technology dyeing process, quartz sand particles can be processed into color-rich colored sand grains. With the colored sand mixed decorative design, colorful colors can be given to the floor. Quartz sand should also be round or spherical granules, to facilitate the free sliding of particles during the construction process, so that the sand can be "closest accumulation" as much as possible, so that the epoxy sand layer is fully densified to ensure that the floor is excellent in resistance to weight Pressure and abrasion resistance. In addition, after the epoxy sand layer is fully densified, the amount of resin on the surface layer can be saved and the cost can be reduced.
