Method for removing fine powder on surface of spherical ceramic powder, spherical ceramic powder and application thereof
The invention provides a method for removing fine powder on the surface of spherical ceramic powder, the spherical ceramic powder and an application thereof, and relates to the technical field of ceramic materials. The method for removing the fine powder on the surface of the spherical ceramic powder comprises the following steps: firstly, mixing the spherical ceramic powder with the fine powder attached to the surface with a solvent to form a mixed solution; separating the fine powder from the spherical ceramic powder in the mixed solution; filtering the mixed solution by adopting a filtering membrane to filter out the fine powder and the solvent to obtain mixed slurry formed by the spherical ceramic powder and the solvent; and finally, removing the solvent in the mixed slurry to obtain the spherical ceramic powder. The method for removing the fine powder on the surface of the spherical ceramic powder is simple in process and easy to operate, the flowing property of the spherical ceramic powder is remarkably improved, and the thermal spraying adaptability of the spherical ceramic powder and the stability of the thermal spraying coating performance can be effectively guaranteed.
本发明提供了一种球形陶瓷粉末表面细粉祛除方法、球形陶瓷粉末及应用，涉及陶瓷材料技术领域，所述球形陶瓷分表表面细粉祛除方法包括如下步骤：先将表面粘附有细粉的球形陶瓷粉末与溶剂混合形成混合溶液，并使得细粉与球形陶瓷粉末在混合溶液中分离；再将混合溶液采用过滤膜进行过滤，使得细粉和溶剂滤出，得到球形陶瓷粉末与溶剂形成的混合浆料；最后将混合浆料中的溶剂去除，得到球形陶瓷粉末。本发明提供的球形陶瓷粉末表面细粉祛除方法工艺简单，易于操作，显著提高了球形陶瓷粉末的流动性能，能够有效保证球形陶瓷粉末的热喷涂适应性以及热喷涂涂层性能的稳定性。
