进口与国产降膜管在固碱工艺中使用寿命比较

Comparison of service life between imported and China-made falling film tubes used in solid caustic soda production

比较了国内外两种降膜管(材质分别为N4和Ni201)在99%固碱装置上的使用寿命,并分析了N4材质优于Ni201材质的原因。

The service life was compared wer made from N4 and Ni201 respectively, The reason that N4 material was superior to between imported and China-made falling film tubes, which and used in production facility of 99 wt% solid caustic soda. Ni201 was analyzed.
