一、“隔开”的应用1.阻止反应。①在钛及钛合金表面形成的致密的氧化物保护膜具有极强的抗腐蚀能力,浸于海水中的钛,十年无锈斑,因此钛及钛合金被用于制造轮船、潜艇和重要化工设备。②氯碱工业中阳离子交换膜将阴极产物氢气、氢氧根离子和阳极产物氯气隔开,避免氯气与氢气,氯 First, “separated ” application 1 to prevent the reaction. ① The dense oxide protective film formed on the surface of titanium and titanium alloy has extremely strong anti-corrosion ability. Titanium immersed in seawater has ten years of no rust, so titanium and titanium alloy are used to manufacture ships, submarines and important chemical equipment. ② chlor-alkali industry in the cation exchange membrane cathode products of hydrogen, hydroxide ions and chlorine anode products separated to avoid chlorine and hydrogen, chlorine
