Abstract

The invention discloses a self-cleaning photovoltaic glass production process, and relates to the technical field of photovoltaic panel production. The production process comprises the following steps: preparing the raw materials in parts by weight: 130-140 parts of silica sand, 50-58 parts of sodium carbonate, 40-50 parts of limestone, 1-5 parts of aluminum oxide powder, 0.5-0.8 part of sodium nitrate, 1-2 parts of Amphibole, 0.2-0.3 part of cerium oxide, 0.4-0.5 part of antimony trioxide and 1-3 parts of antimony oxide; melting; molding: performing calendering molding; heat treatment: spraying a layer of self-cleaning coating on the surface of glass through annealing and quenching processes, wherein the self-cleaning coating comprises the following components in parts by weight: 10-20 parts of shell powder, 4-6 parts of a binding agent, 4-5 parts of starch, 1-2 parts of chlorite schist powder, 1-3 parts of antimony oxide, 4-6 parts of octadecyl silane bonded silica gel and 3-6 parts of peach gum. The photovoltaic glass disclosed by the invention has a self-cleaning function, and dust is not easy to adhere to the surface of the photovoltaic glass and is easy to wash away under the rain, and a large amount of manpower and physical resources can be saved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of photovoltaic panel production, in particular to a self-cleaning photovoltaic glass production process. [0003] Background technique: [0004] Solar photovoltaic power generation system is a new type of power generation system that uses the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. There are two modes of independent operation and grid-connected operation. Independently operating photovoltaic power generation systems require batteries as energy storage devices. They are mainly used in remote areas without grids and areas with scattered populations. The cost of the entire system is high; Save the storage battery, not only can greatly reduce the cost, but also has higher power generation efficiency and better environmental protection performance. Solar photovoltaic panels are generally located in a relatively harsh env...
