Problems solved by technology
Tin coating of the solder strip is a necessary process before welding. Since the current processing technology of the solder strip is rolled and tin-coated into one, and the take-up speed has reached 90 meters per minute, the temperature on the solder strip after tin coating has no time to cool in the air. It is taken up by the take-up wheel, which affects the quality of the ribbon

The invention relates to improved solder strip cooling liquid. The improved solder strip cooling liquid is characterized by being composed of, by weight, 20%-40% of ethyl alcohol, 10%-20% of propylene glycol monomethyl ether, 6%-15% of hydroquinone, 2%-6% of water-soluble oil, 1%-5% of isothiazolinones and the balance deionized water. The solder strip cooling liquid is scientific and reasonable in formula, the cooling performance is good, no corrosion is caused to a solder strip, the hydroquinone antioxidant is added into the cooling liquid so that the solder strip cannot be oxidized after being exposed in air for a long time, use is convenient, the cooling liquid is practical and environment-friendly, production is easy, the raw materials are easy to obtain, energy is greatly saved, smoothness of the solder strip is improved through a small amount of water-soluble oil after liquid is completely volatilized, the guarantee period of the solder strip is prolonged, and a welding effect cannot be affected.
Description
technical field [0001] The invention relates to the field of solar photovoltaic ribbon processing, in particular to an improved ribbon cooling liquid. Background technique [0002] With the rapid development of the solar industry, the ribbon processing technology in solar cells has become an important link for the products of this industry to finally reach consumers. The processing effect of the ribbon directly determines the service life and energy conversion efficiency of the solar cells. Tin coating of the solder strip is a necessary process before welding. Since the current processing technology of the solder strip is rolled and tin-coated into one, and the take-up speed has reached 90 meters per minute, the temperature on the solder strip after tin coating has no time to cool in the air. It is taken up by the take-up wheel, which affects the quality of the welding strip. [0003] Invention content: [0004] The invention provides an improved cooling liquid for welding...
