Nashke rust inhibitor is a water-soluble and affixed coating. When drawn, it is evenly applied to the surface of the cleaning wire. After drying, a dry and transparent film will be formed, and then the thermoplastic sealing package can be used to achieve the expected rust prevention. effect. Corrosion resistance is divided into four categories: three months, six months, one year and two years.
The mechanism is as follows: the single-molecule deposition layer is adsorbed on the metal surface to block the micro-battery action of the metal surface in the atmospheric environment, and the electrolyte corrosion is inhibited. The protective film formed by Nash's rust inhibitor is an extremely thin, invisible single molecule. It does not need to be removed, maintains the natural color of the metal surface, and has self-repairing and self-healing functions to prevent local corrosion and pitting. When copper is plated, the electrochemical corrosion of copper is less than that of iron.
In practical application, each manufacturer can design an alternative rust-proof heat treatment method based on the original process route according to the different drawing lubricants used, the wire-receiving method, etc., which is simple and easy.
The Nash rust inhibitor treated wire and copper plated wire at pH 8.2. After 4% salinity treatment for 4h, the copper-plated wire showed a dense yellow rust point, while the Nashke rust inhibitor treated only a small amount of yellow rust. At the same time, the production cost per ton saved 400 yuan.
This method makes the wire business process more simplified and efficient. The application of this new technology will bring significant benefits to wire manufacturers. Http://news.chinawj.com.cn Editor: (Hardware Business Network Information Center) http://news.chinawj.com.cn
