  • Patent number: 10787820
    Abstract: The present invention relates to an artificial stone tile comprising natural rock and a method for manufacturing the same. According to the present invention, the artificial stone tile may be manufactured by finely crushing natural rock, which is inexpensive to marble or granite, mixing the powder with an adhesive for increasing cohesion, heat resistance, durability and strength, forming the mixture into a tile shape under high pressure, and subjecting the formed tile to first calculation at high temperature, quenching at cold temperature, and second calcination at low temperature. The artificial stone tile may reproduce the same texture as natural stone, has better abrasion resistance and strength, is environmentally friendly without using synthetic resin, and may be supplied at low prices.

  • Patent number: 10662335
    Abstract: The invention relates to the manufacture of composite pigments containing aluminum hydroxide, and their use for improving the pigment light-scattering efficiency in coatings, plastics, paper and laminates. The composite pigment particles contain pigment particles such as titanium dioxide and precipitated aluminum hydroxide and are manufactured by in-situ precipitation of aluminum hydroxide in an aqueous pigment particle suspension. Use of the composite pigment particles according to the invention, based on titanium dioxide, permits savings on pigment with little or no loss of optical properties.
