An apparatus (20) for making nanopowder includes a reaction chamber (22), a first sprayer (25, 27), a second sprayer (26, 28) and a centrifuge (24). The reaction chamber includes a top portion (224); a bottom portion (227) opposite to the top portion; a peripheral sidewall (220, 223) interconnecting the top portion and the bottom portion; an inlet (222) formed in the top portion configured for introducing a solvent; and an outlet (229) formed in the bottom portion. The first sprayer is formed on the peripheral sidewall of the reaction chamber configured for spraying a first reactant into the reaction chamber. The second sprayer is formed in at least one of the top and bottom portions of the reaction chamber configured for spraying a second reactant into the reaction chamber. The centrifuge is connected with the outlet of the reaction chamber.

The present invention discloses a gloss paint, the gloss paint includes: a fluoro acryl-silicon resin in an amount by weight from 20% to 60%, pigment particles in an amount by weight from 5% to 40%, an additive in an amount by weight of less than 5%, the remainder being a solvent. The present invention also discloses a method for using the gloss paint to form a gloss paint layer on a surface of an article. In use, the gloss paint of the present invention can obtain a high gloss finish without a top coat. Thus the present gloss paint simplifies the steps and equipments of using the same, and economizes on the cost of the procedure.
