3 method summary
Spraying through a continuous neutral salt spray 4h after blasting in the box blast 8h, repeat this operation several times to obtain the appearance of the sample changes, loss of quality
Rate and gloss retention, to evaluate the sample salt spray resistance to aging.
4 test solution
4.1 sodium chloride solution
4.1.1 Configure sodium chloride solution
The reagents used in this test preparation by GB/T 603. The sodium chloride dissolved in water in line with GB/T 6682 three water, the concentration of (100 ±
10) g/L of sodium chloride solution stand-by.
4.1.2 adjust the pH value
Using the pH meter, measure the pH value of the sodium chloride solution in 4.1.1 and adjust the pH to 6.5 ~ 7.2. Solution
pH can be adjusted with hydrochloric acid or sodium hydroxide.
4.2 Filtering
The solution is filtered using a medium speed filter before use to prevent the solids in the solution from clogging the nozzle.
5 equipment
