什么是DCS?DCS是分布式控制系统的英文缩写(Distributed Control System),在国内自控行业又称之为集散控制系统。
I/O单元与CPU是通过现场总线连接的。

对于原来有盐酸和硫酸组成的酸洗工艺,算洗的时间过长,酸液的温度也高,去除不锈钢表面氧化皮的效果虽好,但是生产成本高,盐酸经过加温后挥发性更强,散发出的酸雾污染环境并且危害人体健康,对于制品较厚的氧化皮去除不。采用磷酸取代盐酸,能更好地去除氧化皮,且成本低,采用室温酸洗。中和液的作用是钝化后对不锈钢进行中和处理。如果未经过中和处理,虽然经过了水洗,但是酸液仍会有一部分残留附着在不锈钢的表面,其体积分数远远低于柠檬酸钝化液中柠檬酸钝化液的体积分数范围,不仅起不到钝化的作用,反而还会破坏不锈钢表面的钝化膜,使不锈钢表面的耐腐蚀性大大降低,甚至可能会低于未经过钝化处理的不锈钢表面的耐蚀性,故要进行中和处理。
