| 随着社会的不断进步，对工业厂房的净化要求越来越高的医药、食品、电子、精密仪器等行业得到了快速发展，从而促进了环氧树脂地坪的发展。1996年我国开始在制药行业实施了GMP标准，使环氧树脂地坪的应用得到了迅速发展。目前，防腐地坪国内主要是以乙烯基环氧树脂材料为主，环氧树脂耐酸性固化剂的选择也较多。普通的做法一般是在处理好的混凝土地面基层上涂刷封闭底漆层后刮涂几遍中涂层，然后做面层，这种做法满足不了某些工厂车间经常进行酸、碱、热水交替冲洗的使用功能要求。由于需作重防腐的工厂车间经常进行酸、碱及热水的冲洗，腐蚀介质的长期存留会逐渐破坏表层而渗透进地坪里面，当介质渗透进基层与底涂层间积聚到一定程度时，会产生起鼓现象进而造成地坪的破坏。 With the continuous progress of society, the industry of medicine, food, electronics, precision instruments and so on, which requires more and more high purifying requirements for industrial plants, has developed rapidly, thus promoting the development of epoxy floor. In 1996, China began to implement GMP standard in pharmaceutical industry, which made the application of epoxy resin flooring gaopin.37ix.com.cnfangfumu.37ix.com.cn bianyaqifj.37ix.com.cnpvcsuomo.37ix.com.cnshuiniji.37ix.com.cn caiguang.37ix.com.cndevelop rapidly. At present, vinyl epoxy resin is the main material for anti-corrosion floor in China, and the choice of acid-resistant curing agent for epoxy resin is also more. General practice is to brush the closed primer layer on the treated concrete ground base and scrape the middle coating several times, then make the surface layer, which can not meet the functional requirements of acid, alkali and hot water alternating flushing in some factory workshops. Due to the frequent flushing of acid, alkali and hot water in the workshop, the long-term preservation of corrosive medium will gradually destroy the surface and penetrate into the floor. When the medium penetrates into the base and the underlying coating to a certain extent, it will produce bulging phenomenon and then cause the floor damage. |
