Preparation method of self-cleaning microspheres for circulating groove sensitive component of water quality sensor

Abstract

The invention provides a preparation method of a self-cleaning microsphere for a water quality sensor circulation tank sensitive component, the self-cleaning microsphere comprises a glass microsphere substrate, a titanium dioxide cross-linking layer and a fluorinated layer, the titanium dioxide cross-linking layer is arranged on the outer side of the glass microsphere substrate, the fluorinated layer is arranged on the outer side of the titanium dioxide cross-linking layer, and the fluorinated layer is arranged on the outer side of the titanium dioxide cross-linking layer. The glass microsphere substrate is activated to obtain an activated substrate with the surface containing hydroxyl, and the material of microspheres in the glass microsphere substrate is selected from at least one of silicate materials such as sodium silicate glass, quartz glass, high-boron glass and crystal glass. The cleaning microspheres with soft surfaces gently impact the sensitive component of the circulating groove of the water quality sensor, and the titanium dioxide cross-linking layer has bactericidal activity in an illumination environment, so that continuous pellicle is prevented from being formed in the sensitive component of the circulating groove due to growth of microorganisms, and the sensitivity of the sensitive component to monitoring of key water quality indexes can be effectively ensured.
