Problems solved by technology

[0019] (2) Desalted water with carbon dioxide is an acidic environment, and carbon dioxide will destroy the protective film on the surface of copper and aggravate corrosion:
However, in practical applications, it is often encountered that it is not easy to remove dissolved oxygen in brine or adjust the pH value. At this time, it is necessary to find a new method to slow down the corrosion of copper in desalinated water.

Embodiment Construction

[0037] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0038] The invention relates to an anticorrosion method of red copper in desalted water, that is, an openable airtight shading cover is arranged on the outside of the direct contact part of the red copper and the desalted water for light shading.

[0039] The airtight shading cover is made of translucent or opaque material.

[0040] When the copper is directly placed in the desalinated water, the outside of the whole system should be shielded from light or kept in a dark state. For example, when the copper test piece is hung in the desalinated water for testing, an openable airtight hood should be set outside the whole system; When part of the surface is in direct contact with desalinated water, shield the surface of copper that is in direct contact with desalinated wate...

Abstract

The invention discloses a method for preventing red copper from corrosion in demineralized water. According to the invention, the discovery that lighting influences corrosion of copper in demineralized water is utilized, and an openable closed light-proof hood is arranged outside the part, in direct contact with the demineralized water, of red copper to achieve anticorrosion protection of red copper in demineralized water. The method provided by the invention is simple, is easy to implement and low in cost, and enables a red copper-demineralized water system which has difficulty in deoxidizing or adjusting the pH value to be proper due to poor sealing performance to effectively slow down corrosion of copper in photophobic or dark places.

Description

technical field [0001] The invention belongs to the field of material protection, and in particular relates to an anticorrosion method for red copper in desalted water. Background technique [0002] Desalted water refers to the finished water obtained by using various water treatment processes to remove suspended solids, colloids, and inorganic cations, anions and other impurities in water. The factors affecting the corrosion of copper in desalinated water include the dissolved oxygen content of water, pH value, temperature, flow rate, ion and other impurity content, and generally do not pay attention to the influence of light. The corrosion rate of copper in oxygen-free desalinated water is very low. When the air is in contact with pure water (de-salted water), a certain amount of oxygen will be dissolved in the desalinated water, which will increase the dissolved oxygen content of the water. Corrosion occurs in salt water; a certain amount of carbon dioxide dissolved in d...
