一百多年以前,科学家发明了电镀技术,这是防止金属表面不受环境影响腐蚀、生锈的金属表面处理工艺,它通过阳极溶解,阴极吸附的原理在各种易氧化的金属表面形成一层保护层,其应用领域非常广泛。百年之后,随着社会的发展,人们对该项技术的认识已从单一的经济方面转向对环保的重视。电镀工艺除了它的设备投资大、生产成本高以外,生产过程中有氰化物的废气,废水排放,严重地危害了人们的身心健康和生态环境。在日益重视环境保护的今天,电镀工业的发展已经受到了限制。因此,替代电镀的技术革新放在科学家的面前。于是,化学镀应运而生——。
More than one hundred years ago, scientists invented the electroplating technology, which is to prevent the metal surface from environmental corrosion and rusting of the metal surface treatment process, which by anode dissolution, cathodic adsorption principle in a variety of easy to oxidize the metal surface to form a Layer protection layer, its field of application is very wide. A hundred years later, with the development of society, people’s understanding of this technology has shifted from a single economic aspect to environmental protection. Plating process in addition to its large investment in equipment, high production costs, the production process of cyanide emissions, waste water emissions, seriously endangering people’s physical and mental health and ecological environment. With the increasing emphasis on environmental protection, the development of electroplating industry has been limited. Therefore, the replacement of electroplating technology innovation in front of scientists. As a result, electroless plating came into being.
