COMPOSITION soldering acid
Soldering acid "(zinc chloride)
Solder acid "(zinc chloride) are prepared route dissolution of zinc metal in concentrated hydrochloric acid at the rate of 412 g / L. The acid is carefully poured in a bowl with pieces of zinc, the level should not exceed 3/4 of the depth of dishes. In the final zinc dissolution stops bubbling hydrogen. The resulting solution of zinc chloride, allow standing for up to transparency and carefully poured into a vial. Instead of "soldering acid" mozhnoispolzovat flux, made from equal weight fraction of ammonium chloride and glycerol. in this case, the soldering does not oxidize. The flux is suitable plus soldering stainless become.
Flux (ammonium glycerin)
Instead of "soldering acid" mozhnoispolzovat flux, made from equal weight fraction of ammonium chloride and glycerol. This soldering space does not oxidize. The flux is also suitable for brazing stainless steel.
Acetone-rosin flux is not inferior in quality alcohol-soldering rosin. He wets the surface also easily flows into the gap between the solder parts. Therefore, in the absence of alcohol can be prepared in flux as the acetone. However, we must not forget that toxic acetone plus has undesirable sharp odor, so to work with such a flux can only be well ventilated place.
