微晶板材的耐腐蚀性能和吸水率

The Anti-corrosion Property and Water Absorption Rate ofMicro-crystalline Plate Material

微晶板材是优良的建筑防腐材料 ,耐腐蚀性能强 (氢氟酸除外 ) ,抗渗透性能优异。介绍了其试样在ω =2 0 %三大强酸和ω(HNO3) =5 %～ 30 %硝酸中的煮沸腐蚀试验结果及吸水率的测定数据 ,指出酸浓度、温度和时间对微晶板材腐蚀损耗的影响 ,和其优异的抗渗透性能 。

Micro crystalline plate material is a good anti corrosive building material with strong anti corrosive property (except hydrofluoric acid) and good anti penetration property. It introduces the boiling corrosion experiment results and the water absorption data of its sample in three kinds of strong acid ( ω =20%) and nitric acid〔 ω (HNO 3)=5%～30%〕 and points out the influence of acid concentration, temperature and time to the corrosion wearing of the micro crystalline plate material, its good anti penetration property and recommends it for wide utilization.
