Problems solved by technology

Although this kind of flux has good solderability and low cost, the waste gas is filled in the air when there is solder after soldering, which makes the smell of solder smoke in the production workshop pungent, wastes solder, and makes the workshop environment harsh and affects the health of workers. healthy
[0003] In addition, most of the open soldering furnaces in the prior art use stirring to prevent the solder from being oxidized by the air. Solve the problem above, such as the inner tank is heated by the heating rod, the inner tank itself is heated unevenly, stirring can never ensure that all the solder is heated evenly, and the heated solder will always be oxidized in contact with oxygen in the air

Abstract

The invention relates to a full-automatic anti-oxidation soldering tin furnace for reducing exhaust emission treatment. The full-automatic anti-oxidation soldering tin furnace comprises a soldering tin furnace body (1), a tin furnace gas hood (2), a soldering flux tank (3) and a smoke pumping device (4). A pair of "nitrogen curtain" devices is arranged oppositely in the side direction of the widthdirection of the soldering fluid surface of a liner of the soldering tin furnace body (1). The invention further relates to a special soldering flux for the anti-oxidation soldering tin furnace. Rosin and rosin ester form modified rosin resin, and acrylate-modified butadiene resin, polyethylene, polyurethane and furfural resin form a film-forming enhancer. Octyphenol polyoxyethylene ether, succinic acid, anhydrous citric acid, benzoic acid and xylene are compounded to form an organic acid activator, and dimethylcarbinol, benzotriazole and hexamethylene diamine form a solvent. The full-automatic anti-oxidation soldering tin furnace for reducing exhaust emission treatment and the special soldering flux for the anti-oxidation soldering tin furnace can improve the workshop environment, prevent the oxidation of soldering tin in large quantity, improve the production efficiency, and save labor cost for an enterprise.

Description

technical field [0001] The invention relates to an industrial soldering device, in particular to a fully automatic anti-oxidation soldering furnace for reducing waste gas discharge, and a flux specially used for the anti-oxidation soldering furnace. Background technique [0002] The traditional soldering process uses an open soldering furnace, solder bar and ordinary flux. The solder bar is usually composed of tin alloy and ordinary flux. The ordinary flux can improve the auxiliary heat conduction of the solder bar in the soldering process, The role of removing oxidation, reducing the surface tension of the material to be welded, removing the oil stain on the surface of the material to be welded, and increasing the welding area; the flux is usually a rosin resin-based flux composed of rosin, resin, active agent containing halides, additives and organic solvents. flux. Although this kind of flux has good solderability and low cost, the waste gas is filled in the air when the...
