Material description, main characteristics
  • 통상적으로 순수하게 정련된 니켈은 기계적 성질이 우수하고 높은 열전도도를 가지며 많은 부식성 매개물에 대한
    저항력이 뛰어나다.
  • 특히 알카리, 할로겐화합물 및 많은 유기혼합물에 대한 부식 저항력이 뛰어나다.
  • Typical applications
  • Caustic soda production(membrane cell cathodes, evaporation),vinyl-chloride monomer(VCM)
  • production, organic chlorinations, food processing of soap and detergents.
