摘要
本文利用含1 500 ppm H2SO4、250 ppm H2SO3以及250 ppm HCl的混合溶液在65℃加热浸泡试样,再在180℃、200℃高温烘烤试样的实验方法来模拟火电玻璃钢烟囱在运行过程中的腐蚀情况,研究用于火电玻璃钢烟囱设备生产的2种乙烯基酯树脂901和907与相应的纤维增强材料组合的复合材料的耐受性能。结果表明:试样的空泡和分层随实验周期的延长而加剧,空泡和分层的程度与选用的树脂及纤维增强材料的种类相关;酚醛环氧乙烯基酯树脂907比溴化双酚A型环氧乙烯基酯树脂901有更好的耐蚀耐温性能;碳纤维与玻璃纤维复合使用比单纯使用玻璃纤维(C型)的试样具有更好的耐分层和空泡的性能。
Anti-Corrosion performance of specimen made of two types of resin 901 and 907 composited with different types of veil were studied under stimulated conditions which consist of 65℃ soaking in a solution contain 1 500 ppm H2 SO4 ,250 ppm H2SO3 and 250 ppm HCl and 180℃ ,200℃ baking. Results show that blistering appears to have resulted from a combination of time of exposure to the chemical solution, the number of shock cycles, the number and type of veils, and the thermal shock temperature conditions;FRP based on brominated novolac epoxy vinyl ester resin appears to have better resistance to the degradation than FRP based on brominated epoxy vinyl ester resin. Also, a combination of carbon and C-glass veil appeared to perform better than a single C-glass veil alone.
