Water vapor aging test whether experiment: discoloration or corrosion, and the subsequent spots solderability.
水蒸气老化实验：测试是否变色或腐蚀斑点，及后续的可焊性。
The corrosion resistance of organic coatings and the relevant mechanism were studied by using water vapor transmission rate technique and electrochemical impedance spectroscopy (EIS).
通过测试涂层渗 水率以及涂层交流阻抗图谱，评价涂层的耐腐蚀性能，并就其机理进行了初步探讨。
Especially prevent the corrosion effectively from moist, water vapor, dust, various sorts of chemical corrosive gas, chemical corrosive substances such as weak acid weak base;
特别能有效防护潮湿、水汽、灰尘、各种化学腐蚀性气体、弱酸弱碱等化学腐蚀物质的侵蚀；
