Foreword

This standard replaces the national standard GB/T 10834-1989 "ship paint salt water and heat measurement brine salt water immersion method." The main technical differences between standard compared with GB/T 10834-1989 as follows. --- Increase Normative References section. --- Reference standard GB/T 1764 "Determination of film thickness Law", to GB/T 13452.2 "Paints and varnishes thickness Determination. " --- Test standards as the original brine. distilled water to make a 3% aqueous solution of sea salt or refined edible natural seawater; instead of days However seawater or reference ASTMD1141.1998 "artificial seawater Standard Technical Specifications" (Appendix A) preparation of artificial seawater. --- Original standard heat salt water immersion test 21d for a period of adjustment to 7d as a test period. After adjustment --- test temperature is divided into two situations. a) at a temperature of (27 ± 6) ℃ or natural seawater formulated in accordance with Appendix A of the artificial seawater immersion; b) at a temperature of (35 ± 2) ℃ natural seawater or artificial seawater prepared in accordance with Appendix A soak 7d is a period, in each cycle The last 2h do temperature (80 ± 2) ℃ natural seawater or artificial seawater prepared in accordance with Appendix A to soak. --- Adjust the model size requirements, test preparation and coating. --- Added Appendix A synthetic seawater formulations. Appendix A of this standard is a normative appendix. The standard proposed by China Petroleum and Chemical Industry Association. This standard by the National Standardization Technical Committee paint pigment. This standard was drafted. China Shipbuilding Industry Corporation seventh twenty-five Institute, Tu Chemical (Shanghai) Co., Ltd., Zhejiang Flying whale paint Co., Ltd., Marine Chemicals Research Institute, Shanghai Kailin paint factory, Ningbo flywheel-made paint limited liability company, in the construction of Changzhou coating Chemical RESEARCH Study hospital.

3 test device

3.1 Test groove Using saline test tank thermostat, all parts in contact with the test brine by inert material (glass, plastic). Scale test tank Typically. 700mm × 400mm × 400mm, with a lid and thermostatic heating system. Slot throughout brine flow rate and temperature should be substantially Consistent, and to maintain a certain liquid level. 3.2 Mixing System Can be bubbled through the oil-free air (during the cycle refers to the surface traces of oil can not float) or pump circulation stirring. Either stir Mixed mode, must meet so that the entire brine tank are sufficiently stirred purposes. 3.3 Test plate bracket Use is made of non-conductive material, it should enable the test surface perpendicular to the direction of the test plate to maintain 15 ° ~ 20 ° angle. And the tank wall sample is immersed in the tank distance of at least 30mm.

4 Sample preparation and

4.1 Sampling According to GB/T 3186 provisions extraction test product in a representative sample. 4.2 test plate Unless otherwise specified, the test should be used GB 712 sheets of ordinary hot-rolled carbon steel, size. 300mm × 100mm × ......
