Automatic Safe Acid Burning and Color Hanging Cabinet

Heated sulfuric and nitric acid work behind a closed door, with 98 percent of the fume treated.

Overview

What This Machine Is

A PP cabinet for acid burning and colour hanging of gold and silver jewelry: heated sulfuric and nitric acid in German quartz beakers annealed at 1200 C, a fully enclosed structure, an acid gas purification system with pH control, fan and water pump, and a purify efficiency of more than 98 percent.

The problem it is built for

Acid bombing removes the copper from the surface of a gold piece and brings the colour up. It is also the single most dangerous half hour in a jewelry factory. Enclosing it, automating the timing and treating the fume is the difference between a controlled process and an incident waiting to happen.

Features

What Is Built Into It

Fume treated, not just extracted

An acid gas purification system with a pH control device, fan and water pump, rated at more than 98 percent purify efficiency. Extraction alone moves the problem outside; this treats it.

Everything acid-proof

Working tank, exhaust system and frame are all made of acid-proof material, against nitric acid, hydrochloric acid and aqua regia.

German quartz, annealed at 1200 C

Both beaker and basket. Annealing at 1200 C is what gives them the purity and strength to hold up under strong acid at temperature.

Heat-resistant basket handles

Quartz baskets are fitted with heat-resistant handles so jewelry can be moved safely during acid boiling and rinsing.

PLC and push-button control

Heating, timing and exhaust run from an intuitive control panel, which is what makes the process repeatable across operators rather than dependent on one experienced person.

FAQ

Automatic Safe Acid Burning and Color Hanging Cabinet Questions

What does acid burning actually do to the piece?

Two things, per the source: it removes the copper inside the jewelry, and it makes the colour of the jewelry more shining.

How much of the acid fume is dealt with?

More than 98 percent, through the acid gas purification system with its pH control device, fan and water pump.

Why quartz rather than glass?

The beaker and basket are imported German quartz annealed at 1200 C, which is what lets them resist high temperature and stay stable in strong acid or alkali.

Is there a patent on it?

The product data lists an invention patent verification as its certificate. Xinhongfa holds 2 invention patents and 3 utility model patents in total.
