钛制化工设备,在钛与钛,钛与非金属接触的缝隙部位会发生腐蚀而引起装置的早期泄漏,已被越来越多的人所认识。氯碱工业是我国钛材推广最早、应用最成功的一个行业。但工业纯钛在氯化钠的酸性热溶液中会发生间隙腐蚀,这已在我国江南某氯碱厂的30m~2隔膜电槽和1000吨离子膜制碱 Titanium chemical equipment, titanium and titanium, titanium and non-metallic parts of the gap will be exposed to corrosion caused by the early leakage of the device has been recognized by more and more people. Chlor-alkali industry is China’s titanium to promote the earliest, the most successful application of an industry. However, the industrial pure titanium in acid hot solution of sodium chloride will occur gap corrosion, which has been in our country, a chlor-alkali plant in South China 30m ~ 2 diaphragm cell and 1000 tons of ion-exchange membrane
