Copper water pipe has excellent physical stability, high temperature, low temperature, corrosion resistance, strong pressure resistance, not easy to deformation and many other advantages, but also has other pipe does not have the ability to kill bacteria, can kill nearly 99% of the bacteria in the water pipe, can be said to be the ultimate choice of home water supply system.
Copper water pipe is so good, the market has ulterior motives but always take the copper will produce copper green, copper green for the human body has a great harm to say things, then we will talk about these fallacies, so that it does not break.
First of all, the copper element is extremely stable inactive elements, which is the reason why it can become a casting currency material. Copper green is the product of the chemical reaction between the copper surface and the outside world, to generate copper green in the inner wall of the water pipe need to have two stages of reaction:
The first stage To generate copper oxide in the inner wall of the copper pipe, which requires copper and air oxygen, carbon dioxide and other gases and water for a long time in contact with the generation of copper oxide, and our daily use of water pipes, oxygen, carbon dioxide content is very small, so this reaction conditions can not reach, it is extremely difficult to form a copper oxide.
The first stage is so difficult to reach, the second stage of the reaction to produce copper green is basically to eliminate the last possibility of producing copper green, if there are copper oxides he also needs to be in the atmosphere with sulfur dioxide, carbon dioxide and hydrogen sulfide and copper oxides in the surface of the formation of the complex salt, which ultimately formed our so-called copper green, and our daily use of the water basically does not contain sulfur dioxide and hydrogen sulfide, so the The reaction cannot be completed at this stage. At the same time, copper itself with a positive electron, it is impossible to replace the same with the water with a positive electron hydrogen, but also completely cut off the formation of copper green hope, the conclusion is that the copper green in the copper water pipe is almost impossible to generate.
Copper green is not soluble in water
Dr. Toyokawa and Dr. Tian attacked the minister of medical department of the University of Tokyo in Japan with 15 years to do experiments on rats, successively tried copper green, copper sulfate, copper chloride and copper hydroxide and so on 17 kinds of copper compounds, the results of the study denied the copper green is harmful to the human body of the claim that the toxicity of the copper green is extremely weak, and insoluble in water, even if with the food into the human body, with the excretory discharge, will not be in the body. It does not accumulate in the body. The concentration of copper in the environment has been in the safe limit, water supply copper pipe will not contaminate the water quality due to copper green.
