3 Test Equipment
--- Glass cylinder 100mL;
--- Chemically pure ammonium persulfate;
--- CuSO4 chemically pure;
--- Ammonia chemically pure;
--- Ethanol or diethyl ether.
4 Sample Preparation
4.1 Sampling
Sample delivery status by eight product packaging unit (circle or disc) components. Interception of a sample from each sample, each sample preparation
When the depth of the solution is less than L, the specimen should be cut into several sections, the test process.
4.2 Pretreatment
Cleaning coating specimens with ethanol or diethyl ether, and then with a clean, soft cloth and dried. Sealed with wax at both ends of the specimen head so that no copper exposed. Wax seal both ends should not be included in the determination of the length L within.
5 test procedure
5.1 The test solution had to produce ammonium
10g of ammonium persulfate dissolved in 500mL of distilled water, was added aqueous ammonia (specific gravity 0.90) 75mL, diluted with distilled water to
1000mL, prepared test solution temperature should be no higher than 35 °C.
