Black hair of fully automatic soldering irons is related to those inevitable factors
Why does the soldering iron head become black? Everyone knows that the soldering iron head is an indispensable device in the welding industry. The black hair of the soldering iron has a great impact on the automatic soldering machine, and the reduction of the life of the soldering iron head is greatly reduced. In order to improve the welding efficiency of the automatic soldering machine, we must do a good job of maintenance and maintenance of the soldering iron head.
1. Using lead wire and lead-free soldering iron tip will shorten the life of the soldering iron tip, accelerate the oxidation of the soldering iron tip, and black hair of the soldering iron will also appear.
2. Even if the flux is not used, it will turn black. The life of the soldering iron tip of the automatic soldering machine is generally not high, and it will turn black at the end of a long service life.
3. The black hair of the soldering iron of the automatic soldering machine is an oxidation reaction, which is directly related to the flux. General fluxes are acidic and exacerbate oxidation.
4. Oxidation has a large relationship with temperature. The higher the temperature, the faster the oxidation, the acidic flux will accelerate the corrosion of the soldering iron tip.
5. Generally, it is because of tin. Tin is black after oxidation. Ancient copper mirrors have tin, copper, zinc and other components. It is the use of these things to oxidize the surface of the mirror with their oxides. It's bright. http://hfkjbxg.icu/
