An anodic protection cooler for sulfuric acid production has been designed and fabricated.
设计、制造国内首台阳极保护酸冷却器。
It was proved that the anodic protection can not be applied in rotary spherical degester in ammonium sulfite cooking.
结果表明,对亚铵法蒸球不能应用外加电流阳极保护法。
However the poor bond between the anticorrosion casting coating and steel-foot would weaken the anodic protection of zinc.
然而,防腐蚀铸层与钢脚间的结合不良将削弱锌的阳极保护作用。
