My plug-in is not that strong

Three stages
Song Yu clicked on Jiang Miao's chat history.

Recently, Jiang Miao seemed to be annoyed by the old man, so she deliberately moved out to live by herself.Of course, he lived in an exclusive area, but it was just a small building, not a villa.

Song Yu: Brother Jiang, your family has not been targeted by strange people, has it?

Song Yu cut to the chase and went straight to the point.

Jiang Miao: Being targeted?Who dares!
Song Yu: That's good.

Jiang Miao: But I have been away for nearly a month, and I didn't ask about the situation at home.But the old man is very vigilant, and nothing will happen.

Song Yu: Well, to be honest, I was scouted by a certain treasure, which should be the reason for those special items.They couldn't find information about me, so they started with my friends.

Jiang Miao: I know that. Don't you remember the last time I told you that someone was asking about the source of meat?So I went back home and tried to shake them off.It's just that the grandpa at home was nagging too much, so I came out again.

Song Yu: Well, I actually...

Jiang Miao: If you have something to say, brother, don't worry about it.

Song Yu: Can I ask the old man for a request?My sister has been under the surveillance of a certain treasure executive for two weeks. Although she didn't do anything violent, but...

Jiang Miao: It's easy to say. The little snacks you brought made him happy. If anyone dares to do anything to you, the old man will be the first to spare him.

Song Yu: Then thank Brother Jiang, and thank you to our old man!According to investigation, that person is the director of the sales department of a certain treasure.Is this easy to handle?
Jiang Miao: Oh, it's a manager, it's still the sales department, it's okay, I'll ask the old man for instructions.

Song Yu: Thank you!
At this moment, Song Yu really wanted to upgrade as soon as possible. If he reached level 7, he would have travel permission.In this way, if Jiajia is in danger again, Song Yu can rush over there immediately, instead of passively begging others to do things.

He clicked on his property page: Song Yu: Level 15028.5/upgrade balance 238450.5 coins, available balance [-] coins/instrument.

The available balance is very sufficient, but the upgrade balance is only 1.5, which is 10 short of the 8.5 needed to upgrade to level five. If it is level seven, it will be 1000 million coins, which is far away.

It seems that the degradable plastic patent and the subsequent solar energy patent should hurry up, otherwise it would be good to upgrade it in three and a half years only by relying on the water purifier and the daily rate of 61 coins provided by the garbage factory.

However, there are fewer and fewer certain treasure coins provided by recording technology, mainly because the places that should be promoted are almost the same.

Song Yu turned off the virtual chat screen of a certain treasure and went to sleep.

In the following month, until December 12, in addition to sorting out his own microbial data, he also dedicated some time every day to read literature on degradable plastics.

In the purchased materials, there are various records about the development of degradable plastics.

In the next 100 years, the development of degradable plastics has generally gone through three stages, and the basis for dividing the stages lies in their degradation speed.

Phase 2035: In 300, new degradable plastics, with a degradation cycle of [-] days;
Phase 2052: In 100, improved degradable plastics, with a degradation cycle of [-] days;
Phase 2110: In 12, fast-degradable plastics, the degradation cycle is [-] hours!

Song Yu was naturally attracted by the 12-hour fast-degradable type. After all, the small bottle of the body modification agent last time was made of this kind of plastic.

But after reading the introduction, you know that this is impossible to study in this world, at least not now.

As of 2020, there are mainly two types of research on degradable plastics, one is photodegradable and the other is biodegradable, and the latter is obviously more in the current research.

The fast type of stage three is exactly the photodegradable plastic type.

Compared with the current natural photodegradation type that is highly demanding on the weather, the photodegradation in 2110 can even use other artificial lights such as lights, and does not require strong irradiation. The degradation speed is very fast, and the products are also very environmentally friendly carbon dioxide and water. .

However, the equipment for producing this high-tech plastic is quite advanced, and the process is also very complicated, which cannot be manufactured at this stage of the world.

Although the improved type of the second stage does not use particularly advanced equipment, its additive is a special material, which comes from a deep underground rock material, and this kind of rock cannot be obtained in large quantities under the current level of technological development.

Then only the new type of biodegradable plastic in the first stage is left. It just so happens that this new type is indeed new for the present world in 2020.

It is a photo-biological hybrid degradable plastic, which can be degraded by both light and microorganisms.

Compared with the current photo-biological hybrid type, it greatly reduces the cost and overcomes the disadvantage of being difficult to promote the factory.

Of course, this low cost is also related to the increase in oil prices in 2035, which will lead to an increase in the cost of petroleum-based plastics.

However, its main materials are degradable materials such as starch and cellulose, and the cost itself is very low. The key difference between it and the current degradable plastics is also in the additives.

This additive is an antioxidant that can be synthesized artificially, which can reduce the resistance of microorganisms when degrading plastics and speed up the degradation process.

For Song Yu, this new type of degradable plastic, which should have appeared 15 years later, can be used just now, neither requiring equipment nor technology.

It is only necessary to sort out the process and steps of this artificial synthesis, issue it as a patent, and then contact the manufacturer for preliminary production.

"Thank you to the researchers who found such a perfect additive after 15 years!" Song Yu praised.

It took him nearly a month of scattered time to finally determine his research direction for degradable plastics, which was to sort out this synthetic antioxidant first.

Of course, a lot of other things happened this month too.

Let’s talk about Song Yu herself first.

His experiment was finally successful, and he found the appropriate parameters to extract the iron humate material. The next step is to summarize and improve the extraction process of this material, and then measure its physical and chemical properties for use as basic data.

And his two microbiological patents are also under review, and there will be no problems in general.

The completion of experiments and patents also gave him more time to write this patent on synthetic antioxidants.

On the other hand, the old man's work was really effective immediately. The next day after Song Yu asked Jiang Miao to speak to the old man, Jiajia reported that the person who watched her had disappeared.

And when Song Yu told Xiao Qiang the news, Xiao Qiang thought that the pressure he put on Li Zemin had worked.

Song Yu just smiled and thanked him at that time, and didn't expose him, after all, he really contributed.

Perhaps Brother Qiang really played a role in it.

Anyway, since that day, no one is blatantly trying to find out about Song Yu.

Song Yu guessed that the old man should have made a clear statement, and Song Yu was covered by someone!
　I know I still owe two chapters lol

　　too difficult!
