Problems solved by technology

[0002] Chemical industry, the full name of chemical industry, is very closely related to human production and life. In modern life, chemical products are inseparable almost anytime and anywhere. Chemical products permeate in various industries and fields such as home furnishing, agriculture, and industry. Among them, flux is widely used. In industrial welding, the existing fluxes can be divided into inorganic fluxes, organic fluxes and rosin fluxes. Among them, inorganic fluxes are mostly used to clean the oxide film layer on the metal surface, and the existing inorganic fluxes have different ingredients. Uniformity, easy to cause local failure and other problems

Abstract

The invention discloses an inorganic flux. The flux comprises the following components in percentage by mass: 35% to 55% of hydrochloric acid, 20% to 30% of hydrofluoric acid, 15% to 20% of zinc chloride, and 5% to 15% of stannic chloride. By adopting the method, the inorganic flux has the advantages that the welding assisting capability is good, the water dissolving effect is realized, the cleaning is easy, the corrosiveness is high, the oxide films on the ferrous and non-ferrous metal surfaces can be effectively removed, the efficiency is high, and the like; the broad market prospect is obtained in the popularizing of the inorganic flux.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an inorganic flux. Background technique [0002] Chemical industry, the full name of chemical industry, is very closely related to human production and life. In modern life, chemical products are inseparable almost anytime and anywhere. Chemical products permeate in various industries and fields such as home furnishing, agriculture, and industry. Among them, flux is widely used. In industrial welding, the existing fluxes can be divided into inorganic fluxes, organic fluxes and rosin fluxes. Among them, inorganic fluxes are mostly used to clean the oxide film layer on the metal surface, and the existing inorganic fluxes have different ingredients. Even, it is easy to cause problems such as partial failure. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a kind of inorganic flux, which is prepared by using the uniform...
