Container parts constitute the whole container of each unit and container products, there are many different kinds of container fittings and container can be divided into little big high, high, etc, including 20 gp, 40 gp, 40 hq is relatively common. In recent years, container fittings also in rapid development. In the know about the simple concept of container fittings, we also should pay attention to the container some rust protection knowledge, the use of this for us longer container is very be necessary, talking about the container before rust protection to get to know a few concepts and data. Metal corrosion process generally by two ways: chemical corrosion and electrochemical corrosion.
Chemical etching, metal surface with the surrounding medium corrosion caused by the chemical reaction between directly. Such as acid rain, acid fog caused by metal corrosion.
Electrochemical corrosion: metal materials (metal alloy or impure) contact with the electrolyte solution, through the corrosion of the electrode reaction. Such as iron products slow rust in wet or humid environment. According to statistics, every year loss caused by metal corrosion steel accounts for about 10% ~ 20% of steel production. That is to say, the corrosion speed of the steel (in years) and about 10% ~ 20% structure as a whole.
For metal corrosion process is different, the two kinds of anticorrosion measures it is common for chemical substances (such as acid rain, acid mist) isolation, one is the target metal electrochemical protection (such as the golden attribute stronger metal and metal to protect against placed together, making gold properties of strong metal instead of the need to protect metal become galvanic cell cathode first protect the target metal oxide). Besides, a major proportion of container corrosion process is electrochemical corrosion. Because of good chemical corrosion prevention, anti-rust paint can have very good isolation effect. But in the process of container transportation will cut caused ceng damaged, small area of film in the corrosion process of the film break is based on the electrochemical corrosion, and after the rusty spot formation dominated by electrochemical corrosion process is a process of gradually accelerated. At this point, the paint to the protection of lesions of the basic is zero, so in the process of container of anticorrosion of electrochemical corrosion prevention has become a top priority.
