摘　　要：在传统磷酸盐添加剂工艺的基础上，采用聚乙烯吡咯烷酮等有机添加剂改善工作电解液的高温稳定性，提高闪火电压。通过电解液组分的优化，降低电阻率，使传统的己二酸铵／乙二醇加水体系的适用范围从－２５～＋８５℃拓宽到＋１０５℃，工作电压从４～１００Ｖ拓宽到２５０Ｖ。由于中压电解液的电阻率ρ３０℃降至２００～２５０Ω·ｃｍ，低压电解液的电阻率ρ３０℃降至５０～７０Ω·ｃｍ，也可用于高频低阻抗品。A working electrolytic of ammonium ADIPIC/EG system is obtained by adding a variety of additives The electrolytic, containing 30% water, can work at 150 ℃, of which, ρ 30 = 69 Ω·cm, U=300～320 V Breakdown voltage is reduced by ADIPIC acid and solution gaseous pressure by polyhydric alcohol such as mannitol, sorbose, or sorbital Hydration of anodizing oxidation film is restrained by multipolar high polymer such as poval and polyvingl pyrrolidone M nitrophenol is used as hydrogen eliminator (3 refs )
