Reborn I want everything

Chapter 64
After hearing this, Lu Jinming and Zhu Yingying seemed to be shocked by a blockbuster, and said in unison:

"You told your family before that you consulted many experts and professors... Did you actually consult Xiao Gu? Our family invested 600 million yuan in the polypropylene melt blown machine.

Xiao Gu, this is not a joke.Is this actually your opinion?Are you sure?I'll talk about it in detail after dinner. "

Lu Jinming couldn't sit still at all. He listened to his daughter's words a month ago and stopped competing with those traditional old rivals for the supply of raw materials for Zhenyang Refining's EMT production increase. Go out and marry.

To be honest, his decision at the time had a lot to do with the source of information provided by his daughter.

Not only do those principles sound reliable, but also because my daughter swears that these are the advice provided by authoritative professors at Tunghai University.

Now that it was Gu Zhe who said it, although the information is still the same information, the principle is still the same principle, Lu Jinming still can't help but feel nervous, fearing that Gu Zhe's words will not be able to do things firmly.

Gu Zhe smiled wryly when he heard the words, but he knew that there would be a day for this matter, and it was nothing more than a matter of sooner or later.

Now that we have talked about it today, at worst, I will reveal some dry goods at the level of pure thinking.

Anyway, Lu Youyou has already officially become his girlfriend with all his heart. In this case, if you say more, you don't have to worry about leaking the secret, it's all from your own family.

……

So, after simply eating lunch, the Lu family dragged Gu Zhe to the study.

Originally, today was to celebrate Lu Youyou's birthday, and everyone agreed not to talk about business matters, but in the end they couldn't hold back.

Fortunately, Lu Youyou didn't mind, instead she felt a little secretly happy, glad that her boyfriend's ability had the chance to be accepted by his parents.

After Lu Jinming and Gu Zhe sat down in the study, Lu Youyou obediently poured tea for them both.

Zhu Yingying sat in the distance and listened, and the Filipino maids in the house were also sent downstairs to do other housework and were not allowed to approach the study.

After everyone briefly unified the basic consensus on entering the meltblown cloth track, Gu Zhe talked with great eloquence, and talked to Lu Jinming about some dry things:
"Nowadays, the main use of polypropylene melt-blown cloth abroad is to make masks and other fabrics that require adsorption. Of course, the adsorption effect of melt-blown cloth is related to the thickness of the spinneret fibers produced by melt blown.

The finer the fiber, the larger the surface area and the better the pore adsorption effect.You should know this common sense, just like activated carbon is better than ordinary charcoal, because it has a larger surface area.

Therefore, in the business of meltblown cloth, both high-end and low-end can be done.The more the pursuit of adsorption and medical value, the finer the fiber filaments sprayed by the nozzle must be, the efficiency of spraying production will be reduced, and the quality of adsorption will be improved.

If we fine-tune the nozzle and pursue a large output of thick silk, it can be realized quickly. It is completely based on the customer's needs, and what price is given. At present, no one in China makes melt-blown cloth. Even if it is a low-end product, there is definitely a basic market. Guaranteed.And once there is demand and technology to make high-end products, the excess premium is almost pure profit. "

Gu Zhe didn't talk about those unconstrained black technologies first, but gave Lu Jinming a reassurance first, and described the situation in the bottom line - even if you can't make a lot of money, small money is absolutely fine, and you can be very flexible.

After Lu Jinming heard this, he really didn't worry about gains and losses, and he had a deeper understanding of Gu Zhe's behavior:
"This kid is not the kind of person who thinks he is technically gifted, so he is arrogant and aggressive, and he knows to get a guarantee first. No wonder the plan was able to deceive us back then. I really thought it was the opinion of an authoritative professor."

Gu Zhe saw that Lu Jinming's expression became a little more relaxed, and then he began to "climb the upper limit" and draw big cakes.

"In the future, if you want to make a lot of money in the field of melt-blown cloth and engage in high-end technology, you must first further reduce the diameter of the spinneret of the melt-blown cloth. This is a general technological progress that must be guaranteed no matter what high-end products are.

After the spinneret becomes thinner, it can cooperate with many new ideas and discoveries in the field of materials science to solve the problems of the existing melt-blown cloth being impervious to water and not absorbing moisture.It can keep warm, absorb antibacterial, and even one-way permeable and dehumidify.

The specific research and development idea is nothing more than to carry out multi-layer precise melt blown after the diameter of the spinneret is pressed to the nanometer level.For example, a hydrophilic material can be used on the layer closest to the human skin, and a hydrophobic material can be sprayed on the outer layer.

The simplest hydrophilic material is naturally PVA, polyvinyl alcohol.For hydrophobic materials, I haven't studied in depth what to choose.Coupled with some complex stacking and layering processes.I think it is possible to do:

'When the innermost side encounters water, it will be sucked in, and then the water locked in the interlayer will meet the outer hydrophobic structure, and half will be forced out from the pores of the outer layer.The water that is forced out is directly diffused and volatilized, and the half that is forced back to the inner layer is repelled by the outer layer again, and the half is forced out again at a [-]-[-] split. From a macro perspective, the vast majority of water vapor can pass through in one direction. , like artificial skin. "

Gu Zhe didn't go into too much detail about the specific materials, but only cited the hydrophilic PVA as an example, because this is too easy to think of, and Lu Jinming must have thought of it without giving examples. He has been engaged in chemical fiber for so many years, and he must have common sense.

As for the hydrophobic material, PLGA (hydroxypropionic acid-glycolic acid copolymer) is used in related inventions in later generations. This material is very special and can just meet the above-mentioned one-way water permeability needs.

Before Gu Zhe was reborn, he was an expert in the field of additive process materials, and he had read related papers and patent specifications.

The earliest paper was published by the Institute of Nanotechnology, Chinese Academy of Sciences on June 2020, 6 in the June issue of "Science" (interested readers can go directly to "Science" to find the original English version of the paper)

That thing did make a commercially available "artificial skin" later, but it has not been popularized in the field of mask production for a long time-this is not technically unattainable, but economically uneconomical.

According to Gu Zhe's cost assessment before his rebirth, the cost of making ordinary melt-blown cloth masks can be controlled within 70 cents each, while using that material would cost at least [-] yuan each, without any additional technology.

As a consumable, masks will be thrown away after a few hours. Of course, no company will put them into mass production lines.But if it is a luxury and durable product, there are gimmicks and pretentious blessings.Even if the fabric costs 3000 yuan per square meter, it is still possible to make a little.

There are always Nike Adidas Mizuno users who pursue extreme dryness, breathability and warmth will pay for it, or sell it to those outdoor sports geeks.Moreover, after the output of some things increases, the cost of research and development will gradually be diluted.

Of course, Gu Zhe knew very well that with the resources he could mobilize now, even if he knew the principle, it would be impossible to create the same new composite melt-blown fabric as before rebirth.

First of all, the technical indicators of the melt blown machine in 03 and the melt blown machine in 20 years are quite different. The diameter of the spinneret alone is at least an order of magnitude. The machine after 17 years can spray much finer, and the surface area per unit of material And the adsorption effect is much stronger.

In fact, the common medical masks and N95 masks that are common in later generations, in the selection of melt-blown fabrics, the main gap is also reflected in "N95 melt-blown fabrics have finer spinnerets and higher adsorption rates, which can reach 95%". Spray cloth must be finer and more difficult and more expensive.

Secondly, in the research of the Institute of Nanotechnology of the Chinese Academy of Sciences in later generations, a lot of high-tech flower work was done, such as "how to absorb and implant sterilized nano-silver ions between the PLGA and PVA interlayers to achieve long-term sterilization."

There are still many details like this, and Gu Zhe can't realize them right now, so he can only make a relatively simple basic model first.

But in any case, the quality of performance is a false proposition, the key depends on who to compare with.

As long as Gu Zhe gets it out, he can definitely ensure that the relevant performance is unique on the earth in 2003.It is definitely more than enough to hang on the products of the same period, and at least it can hang on for ten or eight years.

With such a blockbuster product backed up by international sportswear brands, they won’t have to worry about losing their status in the world.

20 years later, Shenzhou Ma's Hong Kong stock market value of 2000 billion Hong Kong dollars is not supported by "Nike and Adi are rushing to buy my patented fabrics".

……

Lu Jinming carefully listened to Gu Zhe's analysis, and even asked for many details in person.

After listening to it, the feeling in his heart was completely different from the fragments of knowledge he had heard from his daughter when he first heard it.Many doubtful questions can be analyzed in detail directly to the source of the disease.

After all, Lu Youyou didn't really understand, she was just a knowledge setter, and it was difficult for him back then.

In the end, Lu Jinming let out a deep breath and looked up to the sky with a long sigh.

Zhu Yingying had been sitting in the distance listening, and when she saw this, she hurried over and rubbed his shoulders with concern: "What should I say? Is it okay?"

Lu Jinming nodded, and closed his eyes comfortingly: "God has favored our Lu family, Youyou's life is good, I can rest assured in this life."

Zhu Yingying was quite relieved when she heard this, and gave Gu Zhe a grateful look.

After Lu Jinming came back to his senses, he suddenly remembered something, sat upright, and asked, "Xiao Gu, since you have thought so thoroughly about this thing, and you have done technical research before, why don't you just get a melt blown machine yourself? machine?"

Gu Zhe was taken aback: "I didn't have enough capital at the time, I heard that your machine cost 300 million."

Lu Jinming raised his hand: "Money is not a problem. Youyou also said that you have made 200 million recently. I can help you find a way to leverage more. But I hope you understand: the key for an entrepreneur to make others trust him is All-in , Let investors and followers see your determination.

Otherwise, there are so many second-time entrepreneurs in Silicon Valley, who have been successful before and are very rich.When he started his business for the second time, he still wanted to sell his yacht mansion—this was to show his determination to others, and he put all his family money into his new business.

For some things, you have to go to the game yourself and make a little bet before you can truly discover your potential.I think you should also get one, and it will be convenient for scientific research and debugging at that time.

I said before that the goods will arrive at the end of January and the commissioning will be completed. It will be shipped from Fusang in the next two days. If you add another one, there will not be a long delay. It just happens to be delayed a little and shipped together. "

Gu Zhe thought for a while, and didn't intend to refute. Since he has money, it doesn't matter.Anyway, the melt blown machine will definitely make money this year, even if you don’t engage in scientific research.

I also place some bets myself, just to avoid being regarded as "this is a mouthpiece that teaches people to trade stocks every day, but I don't end up myself".

Gu Zhe immediately agreed: "Okay, but I really can't afford that much right now, I have already arranged the money. For the 200 million, I will pay 60 at most first, and I will have the rest of the balance for two to three months." time."

Lu Jinming: "No problem, I'll help you find a way to turn around first, you can just treat it as a [-]% down payment, and the bill period of two or three months is still flexible."

Weng and his son-in-law have agreed to make a bet and express their views, and they have completely established mutual trust.

They had just chatted speculatively, when suddenly there was a knock on the study door, which made Lu Jinming a little unhappy, so he had to stop talking first.

Zhu Yingying quickly went to open the door, and the Filipino maid at the door seemed to realize that the host would be unhappy, so she quickly explained: "Director Chen from Zhenyang Refining is here."

Lu Jinming's expression changed several times, and finally Zhu Yingying winked, fearing that Gu Zhe would be upset, she explained in the middle:

"Old Chen is also true. The last time he showed his son Youyou's photo, his son never forgot it. But don't worry, we told him that Youyou has a boyfriend in a while, and they retreated."

Hearing this, Lu Youyou also stood beside Gu Zhe, grabbed his sleeves firmly with both hands, and gave him an encouraging look to reassure him.

Gu Zhe patted the back of Lu Youyou's hand lightly, signaling her not to be nervous.

PS: I'm a little sleepy, so I'll go to bed after these two updates.In case you have any questions, please don't worry, leave a message and I will change it after I get up.
