use

1. Determination of lead, zinc, aluminum, iron, cobalt, antimony, nickel and tin. Complexing stabilizer. Auxiliary agent, buffer, desiccant and mordant for acetylation.

2. Used to determine lead, zinc, aluminum, iron, cobalt, antimony, nickel, and tin. Used as an esterification agent in organic synthesis and many aspects such as photographic drugs, medicines, printing and dyeing mordants, buffers, chemical reagents, meat preservatives, pigments, tanning, etc.

3. Used as a buffer, flavoring agent, flavoring agent and pH regulator. 4. Used as a scorch inhibitor for sulfur-regulated chloroprene rubber coking. The dosage is generally 0.5 parts by mass. It can also be used as a crosslinking agent for animal glue.

5. This product can be used for the addition of alkaline electroplating tin, but it has no obvious effect on the coating and electroplating process, and is not a necessary ingredient. Sodium acetate is often used as a buffer, such as acid zinc plating, alkaline tin plating and electroless nickel plating.
