Metal tensile) why rust

Dongguan precision electronic technology co. , LTD. , founded in 2008, is located in shatian ferry road, factory building area of 6000 square meters, specializing in the production of various types of metal tensile, precision terminals, precision shrapnel, lead frame, and other precision metal stamping parts. Stamping is mainly used for all kinds of mobile phones, connectors, plugs and so on electrician electric field. Metal tensile) exist as the atmospheric oxidation ability - - - Namely, stainless, also exists in medium containing acid, alkali, salt erosion ability - - - The corrosion resistance. Metal tensile) is to rely on the general situation of a layer of thin and rigorous constant of rich chromium oxide film ( Protective film) To prevent the oxidation of oxygen permeability, continuous, and ability to resist corrosion. Once there is a certain sign, this kind of film was broken up, in the gas or liquid oxygen atoms will be endless infiltration or metal iron atoms permanent separation, composed of loose ferric oxide, metal profiles also were up to rust. This kind of general situation of membrane was damaged situation a lot, common has the following kinds: 1. Deposited with containing the rest of the metal elements of attachments, or heterogeneous metal particles of dust in the wet gas, attachments and condensed water between the metal tensile, will both together as a micro battery, motivated by the electrochemical reaction, shield membrane were damaged, known as electrochemical erosion. 2. Adhesion juice, organic matter in water is oxygen condition, composed of organic acid the stretch mesh industry point of view, for a long time, organic acid erosion to metal profiles. 3. Adhesive containing acid, alkali, salt substances ( Like to decorate the walls of caustic soda and lime water splash) , prompting some erosion. In the process of production of metal tensile, can according to the characteristics of the product to do surface treatment, can prevent rust corrosion. Precision contact: wish you a prosperous business, everything goes well, if you want to learn more dynamic, can scan the qr code, pay attention to the public. , is committed to precision stamping processing factory of the world's most professional electronic components
