COMPOSITION OF PACIAL ACIDS
Glossary of terms
Soldering acid "(zinc chloride)
Soldering acid "(zinc chloride) is obtained by dissolving zinc metal in concentrated hydrochloric acid at a rate of 412 g / L The acid is carefully poured into dishes with pieces of zinc, the level should not exceed 3/4 of the depth of the dishes. With the final dissolution of zinc, the bubbles hydrogen The resulting solution of zinc chloride is allowed to stand up to the transparency and is also carefully poured into a vial. Instead of "soldering acid" it is possible to use a flux prepared from equal parts by weight of chlorine the ammonium is also glycerin, and the soldering site is not oxidized at all.The flux is suitable for stainless steel soldering.
Flux (ammonium also glycerin)
Instead of "soldering acid," you can use flux, prepared from equal parts by weight of ammonium chloride, also glycerin. At the same time, the soldering room is not oxidized. The flux is also suitable for soldering stainless steel.
Acetone-rosin flux is not inferior in quality to soldering alcohol-rosin. It well wets the surface also easily flows into the gap between the parts to be soldered. Therefore, in the absence of alcohol, you can also prepare a flux on acetone. However, it must not be forgotten that acetone is toxic plus has a sharp undesirable odor, so it is possible to work with such flux only if the space is well ventilated.
