耐高温防腐涂料进展迅速、北美防腐市场巨大。化工厂中钢结构和贮槽等一些设备的防腐涂装,正确选择涂料、施工良好,通常情况下防腐效果可长达10～20年;但如果现场温度高达上百度,结果则会导致深层的过早失效。涂料失效首先源于气侯条件协同的作用,如干湿变化、昼夜差温差和紫外线导致的聚合物降解。目前检测方法已达成的共识是:将ASTMB117盐雾法作为涂料体系选择的方法已受到严重质疑,取而代之的是在
Rapid progress in high temperature anti-corrosion coatings, anti-corrosion market in North America huge. Chemical plant steel and storage tanks and some other equipment, anti-corrosion coating, the correct choice of paint, good construction, usually under the anticorrosive effect of up to 10 to 20 years; but if the site temperature as high as Baidu, the result will lead to deep Premature failure. Coating failure first comes from the synergistic effect of climate conditions, such as changes in wet and dry, temperature difference between day and night and UV degradation of polymers. At present, the consensus reached by testing methods is that the method of selecting ASTMB117 salt spray as a coating system has been seriously questioned, and replaced by
