大型磷酸贮槽的防腐

Anticorrosion for Large Phosphoric Acid Store Ressel

大型磷酸贮槽有磷酸和氢氟酸腐蚀,防腐措施较少,从经济性、实用性分析了主要材料的性能,提出了具体施工方案,并提出一些注意事项,认为选用石墨板进行非金属衬里综合性能较好.

Corrosion exists in large phosphoric acid store ressel for phosphoric acid and hydrogen fluoride, we have less anticorrosion measures; performances of main material are analysed from economics and practicalities, fixative method, some notices are given, too. We think that multiple performance is better if we use graphite plate for nonmetal lining.
