Splashing-proof liquid for welding metal

Abstract

The invention relates to a chemical agent, in particular relates to a splashing-proof liquid for welding metal, belonging to the technical field of metallurgy and chemical industry. The splashing-proof liquid for welding metal is prepared from the following raw materials in parts by weight: 4-7 parts of calcium nitrate, 5-10 parts of zinc oxide, 5-8 parts of butyl cellulose, 10-15 parts of benzyl alcohol, 10-20 parts of graphite powder and 100-150 parts of water. The method comprises: successively adding the calcium nitrate, the zinc oxide, the butyl cellulose, the benzyl alcohol, the graphite powder and the water into a mixer in a material taking sequence, and mixing the raw materials; after the raw materials are mixed, injecting the mixture into a grinding and crushing machine to be ground; and grinding the mixture until the granularity is less than 150 meshes, thus obtaining the splashing-proof liquid for welding metal. During welding, the splashing-proof liquid for welding metal is coated on the surface of base metal. By utilizing the splashing-proof liquid for welding metal provided by the invention, 'weld spatter' can be effectively prevented from splashing, the secondary treatment is not required for a weld spatter ball on the surface of the base metal after welding, the labor intensity of workers is greatly decreased, and the welding efficiency is improved.

Description

technical field [0001] The invention relates to a chemical reagent, in particular to an anti-splash liquid for metal welding. Background technique [0002] Welding process is an indispensable and universally applied processing technology in all walks of life. It is often used in electronics, ships, aerospace, construction, industry, agricultural machinery and other fields. As long as there is a place where metal connections are required, most of them require welding processes. . Welding is to heat the two base metals that need to be connected together by local high temperature through the welding rod, so that the two base materials are firmly connected together by solder. It is a very common phenomenon that "welding spatter" appears in the process of high-temperature heating. The "welding spatter" will fall on the base metal after splashing around. The materials are firmly connected together, and after cooling, a solder flower ball is formed. Sometimes there are many weld...
