Four reasons for rusting of embossed tubes

Release time:


Nowadays, in the market, the application range of the embossing tube is more and more wide, and the application field is more and more. For example, in the household industry, embossed tubes can be used to decorate household appliances, restaurants and cooking utensils, cabinets and bathrooms. Embossing is applied in the construction industry, and can be used as window frame decoration, building exterior wall, elevator car plate, ceiling, tunnel engineering and car plate, etc. In addition, the embossed tube can also be used in aerospace, atomic energy, military, chemical corrosion protection, metal box shell, mechanical equipment shell, shipbuilding, train interior, transportation vehicles and other industrial fields.

Although the embossed tube can be used in many fields and has many functions, the embossed tube is made of metal after all and there is a risk of rust. So what causes the embossed tube to rust?

1. The surface of the embossed tube has accumulated dust containing other metal elements or foreign matter. In the humid air, the condensed water between the accessory and the embossed tube connects the two into a miniature battery, which triggers an electrochemical reaction and the protective film is destroyed. This is called electrochemical corrosion.

2. The surface of the embossed tube may be attached to some organic juice, organic juice in the presence of water and oxygen to form organic acids, organic acids will corrode the embossed tube, but it takes some time.

3. Some acid, alkali and salt substances adhered to the surface of the embossing tube, causing local corrosion.

4. In contaminated air, when the embossing tube encounters condensed water, it will form liquid spots of sulfuric acid, nitric acid and acetic acid, which will cause chemical corrosion.

Therefore, to protect the embossed tube from corrosion and rust, as far as possible to do the following two points.

1. The surface of the decorative embossing tube should be cleaned and scrubbed frequently to remove attachments and eliminate external factors that trigger chemical reactions.

2. In the use of embossed tube, according to the environment to select the appropriate embossed tube.
