Abstract

The invention provides scaling powder special for automatic solar welding. The scaling powder special for automatic solar welding is characterized by being prepared by the following raw materials, by weight, 0.1-0.2% of modified resin, 1.6-2.0% of combined organic acid, 0.1-0.2% of fluorocarbon surfactant and the balance of alcohols solvent. The scaling powder special for automatic solar welding is suitable for automatic welding of solar battery pieces, and is high in welding reliability and low in rate of false welding.

Description

technical field [0001] The invention belongs to the technical field of welding, and in particular relates to a special flux for solar automatic welding. Background technique [0002] Photovoltaic power generation 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. Solar energy is the cleanest, safest and most reliable energy source in the future. Developed countries are taking the development and utilization of solar energy as the main content of the long-term planning of the energy revolution. The photovoltaic industry is increasingly becoming another explosive development industry after the IT and microelectronics industries in the world. Industrial advantages: 1. Never exhaust. 2. The time and cost required to build a solar power station are lower than those of a hydropower station. 3. Mining and using solar energy will not cause environmental ...
