What is a soldering flux? What does the solvent include?
Flux (flux): a chemical that helps and promotes welding processes and has a protective effect and prevents oxidation reactions in welding processes. Flux can be divided into solid, liquid and gas. The main auxiliary heat conduction, removing the oxide, reduce the surface tension of welding material, welding material removal is surface oil, increase the welding area, prevent oxidation and other aspects, in several aspects of the key role of the two is: "to remove oxides and" to reduce the surface tension of welding material".Organic solvent: one or several mixtures of ketones, alcohols, esters, commonly used with ethanol, propanol and butanol, acetone and toluene; isobutyl ketone; ethyl acetate, butyl acetate and so on. As the liquid component, its main function is to dissolve the solid components of the flux, so as to form a uniform solution to facilitate the flux component welding components uniform coating amount, at the same time it can also clean the dirt and light metal surface oil.
There are borax, hydrochloric acid and so on
