Embodiment Construction

[0011] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] Embodiments of the invention include:

[0013] A kind of no-cleaning flux for welding stainless steel is characterized in that it contains the following various chemical components: o-hydroxybenzoic acid, phosphoric acid, zinc chloride, organic solvents, corrosion inhibitors, cosolvents and film-forming agents. The proportion of ingredients by weight percentage is: o-hydroxybenzoic acid 5%-8.5%, phosphoric acid 10%-15%, zinc chloride 15%-20%, organic solvent 1.5%-3%, anti-corrosion agent 1%-2.5%, Co-solvent 1...

Abstract

The invention discloses a clean-free scaling powder for welding stainless steel. The clean-free scaling powder comprises the following chemical components, by weight, 5-8.5% of o-hydroxybenzoic acid, 10-15% of phosphoric acid, 15-20% of zinc chloride, 1.5-3% of organic solvents, 1-2.5% of anticorrosive agents, 1.8-2.6% of co-solvent and 3-4.5% of film-forming agents, and the balance deionized water. Due to the way, the clean-free scaling powder for welding the stainless steel can carry out tin welding on copper and iron materials and can also be used for carrying out welding or chromium plating welding on the stainless steel; meanwhile, by the adoption of the clean-free scaling powder, the weldability is good, poison, environmental pollution and corrosiveness can be avoided, work hours are saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to flux, in particular to a no-clean flux for welding stainless steel. Background technique [0002] Flux is used in the soldering process to help and promote the soldering process, while protecting and preventing oxidation reactions. Fluxes are classified according to their functions: hand dip soldering flux, wave soldering flux and stainless steel flux; the first two are familiar to the majority of users, here is the explanation of stainless steel flux, which is a chemical agent specially for stainless steel welding , General welding can only complete the welding of copper or tin surface, but stainless steel flux can complete the welding of copper, iron, galvanized sheet, nickel plating, various stainless steel, etc. [0003] Fluxes for stainless steel welding have been used in the market for a long time, but for general stainless steel fluxes, there are still various processes such as cleaning and cleaning after welding, which...
