Will hot melt water pipes photosynthesize?

No, I guess it's a thermal effect.

Guangxi News Network-Nanguo Morning Post Nanning News (Intern Cheng Liluan) Recently, the tap water flowing from the faucet of Mr. Long, a citizen of Nanning, often has green flakes. According to the water company, it was photosynthesis that caused green plants to grow in the pipes. Mr. Long doesn't know what these "green things" are.

Worry about the bad health of your health.

Mr. Long lives in Jinhuayuan Community, Zhutang Road, Nanning City. Three months ago, he found that the tap water coming from the tap of his house had green flakes, because there were not many of them, he didn't care, just opened the main gate once in a while to release water. At noon on December 7, when he was about to fetch water for cooking, he found that there were many more green flakes than before, almost blocking the faucet.

As soon as I turned on the faucet, a lot of green stuff came out, and the tap water didn't work at all. Mr. Long said that even the water used for washing vegetables should be precipitated and filtered several times. He reported to the community property management office, but the property office did not know the reason.

I want to know what these things are and if they have any effect on the body. ”

In the morning of August, the author and Mr. Long went to the property management office of the community to understand the situation. A staff member surnamed Wen told me that they did not know what caused it, and that they had reported it to the water company, and the other party said that it was possible that photosynthesis occurred due to solar irradiation. However, what puzzled them was, if it was photosynthesis, why didn't other households have this phenomenon, and Mr. Long's house was so "special"?

On the same day, the author got in touch with the Nanning Water Supply Company. A staff member said that the appearance of green flakes was mainly caused by photosynthesis. Subsequently, the author consulted with the **** testing center of Guangxi Greentown Water Co., Ltd.

A staff member surnamed Weng said that if the material of the plastic water pipe can not be well isolated from light and oxygen, long-term oxygen infiltration is easy to make the pipe grow green algae similar to "moss". He also said that the higher the floor, the more light it is exposed to, and the faster it grows. If it's the same situation, sooner or later other users will find themselves in a similar situation.

Mr. Weng further explained that the cause of this green microorganism may be that when the water pipe was installed, the construction party did not clean the water pipe, resulting in the stagnant water staying in the plastic pipe for a long time, and under the action of microorganisms, the inner wall of the water pipe formed "moss" and scaled, and after the action of the disinfectant in the tap water, the "moss" fell off in blocks and flowed out with the tap water.

Is drinking such tap water harmful to humans? Mr. Weng said that according to their tests of the green flake flow through the water, no toxic substances were found. However, tap water, where impurities are visible to the naked eye, does not meet the consumption standards.

The solution to this problem is to regularly flush the water pipes with plenty of tap water. However, Mr. Yung still suggested that the public should replace the plastic water pipes.

If the plasticizer used in production is a benzene-containing plasticizer such as DOP, the plasticizer will precipitate into the water during long-term changes in the external environment, and then enter the human body or animal, which will cause cancer and other diseases in the long run. And because its external PPR glue can not be well repaired after weathering, it often leaks after welding with new pipe fittings, which makes people helpless, which is rare on other PPR pipes, so the aluminum-plastic PPR pipe is disliked, and it is inevitable. However, if you know anything about water pipes, you will know that in the past, just ten years ago, most of them would choose aluminum-plastic pipes, but now they are not used.

So why is this happening? This is the question that the home miscellaneous altar wants to answer for everyone.

PPR tube adopts hot melt technology, and the process is relatively complex and prone to problems. If defects are prone to occur, stress concentration will be formed, which will affect the long-term performance of water pipes. In addition, during the hot melt process, the material will also be aged.

It can also be dismantled and removed at any time, and the aging resistance is much stronger than that of PPR, but try not to use joints for aluminum-plastic pipe burial, there is a risk of water leakage. The heating PPR pipe with a longer age is afraid of the sun, and the joint is easy to powder.

There are many types of PVC pipes, such as PVC water supply pipes, PVC drainage pipes and other pipe bodies, such as wire casings, as well as new material PVC-M pipes. PVC pipes used for domestic water - tap water must be PVC water supply pipes, and cannot be replaced by PVC pipes for other purposes. Anti-aging agents and other auxiliary materials, these auxiliary additives are at least not beneficial to human health, and at a temperature of 50 degrees, the ingredients of auxiliary additives are easy to precipitate, and the tap water used in life will be polluted to varying degrees, and at the same time, it will bring harm to human health.

As a water supply pipeline on civil buildings, PPR or PE pipes are generally used in the form of hot melt and electric fusion connection, and PVC and ABS, which are different from them, are now not commonly used. This is because hot melt pipe has its unique advantages, such as being able to withstand high pressure, long aging resistance and long life.

Because this kind of water pipe is more anti-bacterial, and it is also anti-virus, I feel that it is good for the body, so I will replace it.

Because the heat preservation effect of the hot melt tube is better, the most effective way to reduce the calorie diet, can save resources and energy.

Because this kind of pipe is easy to install, heat dissipation is good, and it is inexpensive and has strong anti-aging ability.
