Desalination materials?

Lei Ziqing was very surprised after hearing this. The value of this thing is no less than Qingyang Steel, or even much higher!

You know, although more than 70% of the world’s area is water, most of it is sea water, and only less than 2% is fresh water!

Among them, the fresh water that can be used by others only accounts for three hundred thousandths of the world’s total water, that is, a few tenths of percent of the total fresh water storage, because most of the fresh water is groundwater and surface fresh water. rare。

At present, more than half of the world’s land area, spread over more than 100 countries and regions, and more than 2 billion people in total are suffering from water shortages.。

Moreover, human beings are consuming water resources with fresh water demand doubling every 15 years. So far, human fresh water consumption has accounted for 54% of the world’s available fresh water.。

In other words, there is less and less fresh water available, but humans consume more and more fresh water, with consumption doubling every fifteen years.。

Humanity’s current consumption of fresh water has reached 54% of available fresh water. Doubling it will exceed 100%.。

In other words, after fifteen years, the original available freshwater resources will not be able to meet human needs. People will need to exploit more underground freshwater, or make up for it in other ways!

Exploiting underground fresh water that goes hundreds of kilometers underground, not to mention the damage to the environment, will lead to the danger of land collapse; the difficulty alone is not much easier than extracting oil, and the cost of drinking water will inevitably increase. will rise。

It can be imagined that drinking tap water now costs hundreds of yuan a month for residents; by that time, the monthly water bill may cost nearly a thousand yuan. In a few decades, the poorer people may not even be able to afford drinking water. !

Of course, the reality may not be so serious, but water shortages are certain.。

Therefore, people have always been publicizing the importance of water resources, and various countries have invested in the research and protection of freshwater resources. In people’s unified understanding, compared with the exploitation of groundwater, the development of seawater desalination technology is best solution。

In fact, seawater desalination technology has been used in reality decades ago, but the efficiency of seawater conversion is not high, and the cost is high, and it is difficult to supply the lives of ordinary residents like ordinary tap water.。

For example, in the Middle East, where deserts are widespread, there is no shortage of oil but water. Water is more expensive than oil there!

In order to solve the problem of domestic water, Persia, Parthia and other countries have built many desalination plants on the coast, barely maintaining their domestic fresh water needs.。

This means that they have oil underground, and if they have the money to build it, for example, in some poor countries in Africa, even if desalination plants are built, no one can afford to drink the water in them.。

In the coastal areas of China, there are also many seawater desalination plants. The average cost of desalinating one ton of seawater is about 8 yuan. For ordinary tap water, residents’ domestic water is 2.8 yuan per ton, and its cost is nearly more expensive than

residents’ water. three times!

If the water used by ordinary residents is changed to desalinated seawater, if the cost is included, it will cost at least ten yuan per ton?

“How much improvement does this new type of seawater desalination material have in efficiency compared to previous seawater desalination materials? What’s the cost?”

Lei Ziqing asked, he needs to know the conversion efficiency and cost of this material in order to estimate its value and decide how to use it.。

“It’s hard to compare the specific efficiency. I can only say that after using this material, excluding labor, the cost of desalinating one ton of seawater will not exceed one cent!”

“So low?”

The cost of desalinating one ton of seawater is no more than one cent, which is basically free of charge. Not to mention it is more efficient than other seawater desalination, it is cheaper than ordinary tap water!

“Why is it so low?”

Lei Ziqing is a little unbelievable. Although they say technology changes life, this has changed too much.。

“Because the cost of making this material is very low, it is similar to making ordinary plastic films. By simply filtering and dialyzing seawater, we can get pure fresh water, without any other processing during the process; and such materials are disposable It is guaranteed to desalinate hundreds of tons of seawater and can even last longer!”

Chen Xuesong’s words make it very clear. The cost does not exceed one penny, simply because one penny is the smallest unit of price. In fact, not only does the desalination of seawater per ton cost no more than one penny, even ten tons, One hundred tons of seawater desalination costs less than a penny!

With such a low cost, it is certain that once this material is popularized, the problem of fresh water resources that plagues the entire world will be completely solved.。

From this aspect, this seawater desalination material definitely has a much more far-reaching impact and role than Qingyang Steel!

“This is another black technology!”

Lei Ziqing sighed, but at the same time, he also had some difficulties in how to use this material.。

Black technology like Qingyang Steel was developed before, and now this seawater desalination material has been developed. These are all black technologies that are beyond common sense. If this were announced to the world, it would be very high-profile and would also bring about many problems. trouble。

Apart from anything else, Qingyang Scientific Research Institute is expected to be on the list of major powers around the world in the future, and there will probably be many agents and spies of all kinds.。

“This matter is not urgent. Let me prepare slowly before talking.。”

After thinking for a long time, Lei Ziqing decided to press the matter first and not rush to take out the desalination materials.。

He likes to make decisions before taking action, just like when he deliberately showed off his strength before interviewing Qingyang Gang, he needs to make the preparations first and plan ahead so that he can deal with it calmly when things really happen.。

“Boss, this material has not been officially named yet. Do you think we should give it a name?”

“Just call it ‘Qingyuan Film’!”

Lei Ziqing said casually that water is the source of life. With ‘green’ as the prefix, it is just right to name it ‘Qingyuan’.’。

It is called Qingyuan Membrane because the material itself is in the form of a film!
