operation of some salt spray corrosion tester:

1. Preparation of acetic acid/salt spray solution accelerated by salt spray corrosion tester

In the first step, the chlorinated na solution conforming to the chemical purity of GBl266 was obtained in the third grade water conforming to GB6682 with a concentration of (50 + / 10) g/L. The second step is to add reagent grade copper chloride (CuCl221120) into the 3.8-liter brine to mix it thoroughly. Step 3. Adjust the PH value of the solution with acetic acid and make it within the range of 3.1 to 3.3. Should the PH measurements taken at 25 ℃, good solution filter need to the rear can use.

2. Preparation of neutral saline solution by salt spray corrosion tester

First of all, the result is to use PH paper at 25 ℃ was developed for the determination of the test solution PH value of 6.5 ~ 6.5. The chlorinated na meeting the chemical purity of GBl266 was dissolved in the third grade water meeting GB6682, and the concentration was (50 + / 10) g/L. The solution of pure hydrochloric acid or hydroxide na can be added to adjust when out of range. The prepared solution can only be used after being filtered.
