"They are very willing to spend money, and I heard that the price of perfume is quite scary."

"That's true, about ten days ago, a new batch of American perfumes purchased by the Maidno Merchant House was sold for 31521 bottles."

"I'll you, how much do we sell to Lao Huang?" Someone on the industrial side is starting to get depressed.

Xiao Jing flipped through the record book, "The price we gave Lao Huang in these transactions is ninety-six taels. ”

"No wonder that old fox is so happy every time he trades, and he just gives money without even blinking his eyes." Several groups began to complain.

"We can sell our goods not only through the Yellowstone line, but also through other trade routes." Comments were made.

Several members of the executive committee got together to discuss a few words, and then resumed their respective sitting positions. Yang Minghuan knocked lightly on the table, and the surrounding noise suddenly quieted down.

"After discussion by our executive committee, it was decided that the future products could start to find sales through other channels, but since the perfume line has become so large-scale here in Huangshi, if it is directly withdrawn, it will inevitably cause the fear of other maritime merchants who cooperate with us, and it is inconvenient to take it back. We can find other products to trade. ”

At this time, Liu Yeqiang of the industrial group stood up, "I think we have several excellent products to sell to the people of Medno, and in terms of the momentum of their perfume purchases, they are willing to pay as much as they want." ”

Liu Yeqiang has been working in a technical department before, and has long been obsessed with the study of industrial design and neglected the management of interpersonal relationships, so he has always been at the bottom of this technical department. He usually just likes to browse funny posts on the Internet to relieve stress, so the ghost envoy almost participated in the crossing. However, although this technical nerd is not tall and has no money, he really has a lot of technology and ideas, and he is leading the team to deal with many industrial bottlenecks.

Yang Minghuan made a gesture to please continue, and Liu Yeqiang continued. "This ...... just now" he suddenly froze, unable to remember the name of the captive.

"Zhou Laosan." Zhang Yuan helped him replenish.

"Oh yes, Zhou Laosan said that the people of Maidno are adrift on the ocean all year round, and there are only three sources of fresh water. Rainwater is harvested, cooled by seawater, and recharged by land. ”

Zhou Laosan was full of doubts about this tall man who stood up, he didn't know what special opinion this thin tall man had on his nose with a glass on his nose, "Is there any other way to get fresh water on the sea?" ”

The era he lived in was basically the craziest time of the Age of Discovery, although there was a great deviation between time and space and the history of the earth, but the people of his time and space were still full of curiosity about their own world, and he even once listened to the people at the table next to him talking about tea in a teahouse when he saw someone in the West writing a book saying that the world was a round ball, and when he talked about the strange creatures on other continents, he couldn't help but be like a river and foaming at the mouth, which made a lot of listeners linger. But if you want to explore, you can only go by sea boat, you can go without food for a few days, but you can't go without drinking water for a few days, and if you don't drink water for three or five days, you will die of extreme prostration. Once, he boarded a Yaning boat and saw that the fresh water barrels were piled up in it, which was full of algae, and the smell was so bad that the sailors had to add "rum" to it after filtering it. (This is normal, a few years ago, Anhui Chaohu cyanobacteria outbreak, although the waterworks can filter out all the dirt inside, and meet the standard of edible level, but can not eliminate the taste of cyanobacteria inside, and finally people can only choose to buy bottled water to drink.) That's why most of the sailors of that era were drunkards, because they couldn't drink the water without adding it. Drinking this kind of water all year round will not be healthy for any person.

"Yes, we can sell RO water filtration units to them." Liu Yeqiang smiled and threw a bombshell directly.

"I'll it! RO system? What is it? Most of the people present were full of curiosity about this new term, and even Zhou Laosan looked at Liu Yeqiang with a studious and willing to drill demeanor.

"ROSYSTEM Chinese name is reverse osmosis membrane filtration system, is a membrane separation technology developed in the sixties, its principle is that the raw water passes through the reverse osmosis membrane under the action of high pressure, and the solvent in the water diffuses from high concentration to low concentration to achieve the purpose of separation, purification and concentration, because it is opposite to the direction of penetration in nature, so it is called reverse osmosis. Reverse osmosis can remove bacteria, viruses, colloids, organic matter, and more than 98% of dissolved salts from water. This method has the characteristics of low operating cost, simple operation, high degree of automation, and stable effluent quality. ”

"And something so rebellious?" Someone exclaimed, "Isn't that just a thing like this to be able to cross the ocean?" ”

"Theoretically, yes, but you have to have a battery, otherwise the pump can't pressurize the seawater through the reverse osmosis membrane and you won't be able to filter the seawater. Of course, manual pumping can also achieve a certain effect, but it will cause damage to the reverse osmosis membrane due to the unsustainable water pressure. ”

"I think there's a consensus that electricity-related technology isn't available to the indigenous people right now." Du Yande interjected on the side.

"Yes, the only way to do this is to lift the sea water into a tower and filter it through the pressure created by the height difference. Although it will be more troublesome, it is far easier than boiling seawater by collecting rainwater or using the hard-won fuel collected from boats. As for the purchase of RO systems, it is also far less economical than transporting large quantities of fresh water from the mainland. If you have a way, you can discuss it with them. Liu Yeqiang smiled, pushed his glasses, and continued, "The demand for perfume is caused by their dissatisfaction with their own hygienic conditions, if they purchase RO systems, then fresh water will not become a bottleneck restricting their hygienic conditions, and their demand for toiletries will also become very abundant, whether it is soap, toothbrush, toothpaste, mouthwash, shampoo, shampoo, shower gel, or even toilets, bathtub showers, they can be traded as commodities." One of the advantages of this is that we can all make our own things after traveling through the past, without having to rely on buying them in large quantities from us. ”

"What about reverse osmosis membranes? Can we afford to produce our own? Xiao Jing questioned.

"China has the production technology of reverse osmosis membrane, as early as 1958, China has invested in the research of seawater desalination, and the technology at that time was mainly focused on the desalination research of ion exchange membrane electrodialysis; Subsequently, in 1967, the State Science and Technology Commission organized the National Seawater Desalination Battle, and organized the national elite battle for seawater desalination in various disciplines such as water treatment and analytical chemistry, materials chemistry, and fluid mechanics. In 1970, the main force of the battle gathered in Hangzhou, Zhejiang Province, China, and organized the country's first seawater desalination laboratory. During this period, they have been using electrodialysis technology for seawater desalination, successfully developed a special microporous filter membrane for marine monitoring, and built the world's largest electrodialysis desalination station - Xisha Yongxing Island desalination station. At one time, it became a world leader in desalination. In 1984, the State Oceanic Administration established the Hangzhou Water Treatment Technology Research and Development Center of the State Oceanic Administration with the Seawater Desalination Research Laboratory as the main body, and China began to pay attention to membrane technology. In 1992, in order to catch up with the gap between membrane technology and the world, the country established the National Liquid Separation Membrane Engineering Technology Research Center based on the "center", and began to quietly develop domestic reverse osmosis membranes. In 2001, a membrane product company in Hangzhou was publicly launched, and China has also become a country that has mastered independent reverse osmosis membrane technology. I suggest that the Executive Committee purchase reverse osmosis membrane production technology from them, which will be a great help to our development in the new world. ”

Liu Yeqiang's speech made everyone excited, there is such a good thing, when he arrives on the ocean over there, he is not walking sideways on the ocean! If you have a good gun, you can also build your own cannon, buy two six or seven thousand ton freighters, and drinking water at sea is not a problem, then it is not an invincible existence of the overlord?

"Please wait a minute," Zhang Yuan interrupted everyone's surging associations. "What is this reverse osmosis membrane made of? Why do I think this...... Membrane...... Will be with ...... Plastics...... Matter? The more he spoke, the more he felt less confident, and he began to stutter a little when he hesitated.

"Uh......" Liu Yeqiang was also stuck, "As far as I know, the reverse osmosis membrane is the core element to achieve reverse osmosis, and it is an artificial semi-permeable membrane with certain characteristics made of simulated biological semi-permeable membrane, which is generally made of polymer materials. Such as cellulose acetate film, aromatic polyhydrazide film, aromatic polyamide film. The diameter of the surface micropores is generally between 0.5~10nm, and the size of permeability is related to the chemical structure of the membrane itself. Well, it's true that plastic is needed. ”

At this time, the surging associations of the people just now suddenly disappeared, not to mention mass production, this thing is said to be impossible to make in the laboratory, and it is useless to buy technology. At most, it is used as a technical reserve to see if it can be developed when I am old in forty or fifty years.

"I think this technology still needs to be purchased, since we need to go to sea for ocean trade, we can't bring fresh water all over the ocean, let alone the steam engine that will be installed in the future, that thing must use soft water. You can't use a pot to boil soft water for the boiler, right? Xiao Jing grabbed his notepad and said with a smile. It's true that plastic can't be produced now, but what about the future? We can't just rely on the steam engine to win the world, right? ”

He looked at Zhou Laosan, who was sitting in the middle, and said to the people in the sports group, "Take him down first." Let's have a meeting first. ”
