| 摘要 |
The present invention provides a high-concentration flux for being sprayed on a preform. The flux has a composition comprising, based on weight percent, 35-50% of a film-forming agent, 1-20% of an active substance, 0.1-1.5% of a surfactant, and 0.005-0.02% of a dye, with the balance being a solvent. The flux has the advantages of excellent coating performance, highly controllable coating amount, high activity, and low active substance residue after welding, and is suitable for the efficient spraying process and highly reliable welding of various preforms. |
