The staff didn't have to look back to know that this was Sister Bai Jiebai.

The only person who dares to tell the truth on any occasion is her white sister.

The staff member's name is Yang Youxing, maybe his parents want him to walk with his friends for the rest of his life. He is a third-rate college graduate who studied mechanical and electrical engineering.

His story is simple and has no headline. Let's take a look at Bai Jie.

Bai Jie is a good friend of the female Professor Wu Yongmei. Both of them have shared pain and pain, so they can come together firmly.

Shared pain gives people a natural sense of closeness.

In the first time after the crossing, both of them felt a warmth at the same time instantly returned to their lower abdomen, and that warmth drove away the coldness and cruelty brought to them by the world, and the responsibility and power of women returned...... At the same time, they find that their youth has returned, their bodies have become slimmer, and their skin has become smoother...... Time is the most useful cosmetic in the world, it's just that it's too expensive...... I have never heard of a woman who can buy it, not even Wu Zetian, who has a noble and supreme status, and even more so the first sister of electricity...... But the traversers traded the adventures of their lives for ......

The two hugged each other and cried like two children, not caring about other people's feelings at all.

I really hope that those tears can take away all the harm that the world has brought to them...... Hope.

Later, they unconsciously became good friends.

When Wu Yongmei later returned to Relanza City, Bai Jie could have come back, but she chose to stay. Because with the stabilization of the career of the travelers, the production of camphor has also stabilized, and with the camphor captured by the travelers in the city of Geranza, finally, the production of celluloid can begin.

Before the crossing, when everyone laughed at the biggest shortcoming of the cardboard shell bullet designed by Li Ziqiang, that is, it was not waterproof, Sun Defa, who was breezy and calm, moved in his heart, and he thought of celluloid shells.

Later, after experiments, he proposed a solution, which made Li Ziqiang, who always tried every possible way to suppress other people's equipment quotas, vigilant.

"Don't fool me, isn't celluloid just about ping pong balls and glasses? It's not flame-resistant, it's not heat-resistant, can you still put a bullet in it if you don't put a few shots? When I was a child, I burned several broken ping-pong balls, and when I was fighting with others, I also clicked on the broken temples of my glasses, and it was easy to burn. Don't try to use this excuse to ask for more shares......"

Sun De smiled and whispered, "We can modify it, you see." ”

He took out a white piece of porcelain-like for everyone to see, this is a piece of celluloid, which Sun Defa prepared in his laboratory.

Li Ziqiang took it first, took out a lighter and lit it, but there was no rapid burning like the imaginary broken ping pong ball, which is a bit similar to the fireproof effect of bakelite.

Sun Defa said: "It's very simple, just add one percent of the silicon whisker and 0.5 percent of the nitrogen and phosphorus flame retardant coupling agent to it." ”

Li Ziqiang was still very vigilant and said: "Since there is a certain degree of flame retardancy, why will this material be rarely used in future generations?" I haven't heard of this in years. ”

When Li Ziqiang lit the celluloid, Song Shida listened to Sun Defa's soft introduction.

Song Shida thought for a while and said: "Now you put the bicycle on the engine of the motorcycle, it can also reach high speed, but can others use it as a motorcycle?" ”

Li Ziqiang rolled his eyes and immediately understood what he meant, but he still said, "Tell me clearly, what do you mean?" ”

Song Shida knew how to deal with him, so he said leisurely: "It is said that some people were often beaten when they were children, and they even knew how to ...... their glasses when they could point them casually."

Li Ziqiang suddenly blushed, and said loudly: "Do you know what to say, who broke my glasses legs, which guy's clothes were not all pulled off by me!" ”

After shouting, he immediately changed the topic and said, "Fa Zai, let's not go off topic, do you want more equipment?" If there are too many, this celluloid function is too monolithic...... Not cost-effective. ”

"Not much. An ordinary distillation machine, a blender, and a few strainers are enough, and the rest can be solved manually. ”

"Yes! Why didn't you say it earlier, if this half a day was in vain," Li Ziqiang smiled, "The blender can also be done by people, right?" ”

"If you mix it manually, I'm afraid it won't be even...... Still too tired......"

"It's okay, when the ambassador is in charge of this, he has energy, and he played the best table tennis in the basketball team that year."

Jianguo'an has been ignoring their bickering, he checked on the Internet, and said: "This silicon whisker can be solved in a few years, you see, it can be diatomaceous earth as raw material, the raw material is sintered at a temperature of 1000~1200 °C, and then put into a carbon container, in the roaster, heated in a nitrogen-ammonia atmosphere of 1000~1450 °C for 24h, and a whisker with a diameter of 0.1~2μm and a length greater than 10mm grows on the outer wall of the container." The temperature requirements are not high, and when nitrogen and ammonia come out, even if the laboratory method extracts it, it is feasible, but the coupling agent you said is a bit more complicated, at least ten years, right?! ”

"That's right," Sun Defa said heavily, "This coupling agent only has a shelf life of two years, although it is small, it must have ......."

Wu Dapeng was not present at that time, and after he learned about it, he said: "Two years is enough, two years can't settle down, and it's a fart!" Besides, don't judge that side by the current anti-fire effect...... Fat boy, what if you only use that? ”

"The anti-flame level can only reach the level of film films in the forties and fifties, and it is possible to spontaneously combust once after a hundred playbacks......"

Damn, everyone shouted together. That's enough!

Li Ziqiang asked Sun Defa again, what is the use of celluloid.

"Women's ornaments, records, photos, billiards, waterproof pads or coatings, can also be used as windshields, which are more shock-resistant than glass."

"You have so many voices, and the last two are the most useful. I'll use it on my steam cart when the time comes......"

Song Shida said: "Even you can make buttons and glasses!" ”

Li Ziqiang was angry at that time and said: "Fa Zai, Jianren, let's drink, don't take him!" ”

The crowd finally persuaded him.

Celluloid is one of the earliest plastics in the world, its production process is simple, of course, the equipment is not complicated, its production process includes dehydration, distillation, stirring, filtration, calendering or extrusion, drying, chipping, shear arrangement, drying, glazing and pressure leveling.

It can also be injection molded and extruded at around 100 degrees Celsius. The traversers really like that. Its raw material requirements are even simpler, all low-nitrogen nitrocellulose that can't be made into explosives can be sent here, and nothing is wasted. Alcohol and camphor, even more simple things. Of course, a little lubricant, vegetable oil. The traversers use palm oil directly, how about it, go up the grade.

Together with the modifier prepared before the crossing, you can make a shell. After a test before crossing, with a frequency of ten rounds a minute, there is no problem with two rounds.

The rest of the celluloid products can be used without modifiers, unless they also want to be used in electrical appliances, but by then the bakelite may be able to be produced, and everything is a matter of time.

The key issue of production is safety!

What's more, the whole production process, everything is flammable and explosive! Management is a big problem!

So when Bai Jie took the initiative to take on this work, the traversers clicked on her file.

She was an experimental analyst in the world, and she was good and experienced.

I read the comments again, careful, sensitive, and calm. Totally competent!

But she's a girl...... However, do you still use her for the work of contribution?

This is not the first time Bai Jie has come to the Chiji Agricultural Base. But every time she comes, the boys here get to know her better, and she speaks so directly, sometimes she doesn't save face.

She had come to Akai to deliver celluloid linings and dyes to the garment factories here, as well as the alcohol. Of course, the main thing is to look at his best friend Wu Yongmei.

The dye is extracted from the bark of the mangrove trees that grow on the shore, and the traversers are destructive, but they don't waste anything. But what kind of extraction is that, boil. Indigo was captured, and the city of Geranza had already sent it.

From this, we can deduce that the new military uniform of the Akito may be dominated by these two colors.

Maybe the Lobster Soldiers are coming.

Yang Youxing, a staff member who was in Kavin, hurriedly got up and said, "Ah, Sister Bai, you are here, I can't stand this card anymore, I just took the review book to practice writing." Hurry up and help me. ”

Bai Jie is good, if you see someone who really needs help, a few words. Straight-tempered people are actually the most warm-hearted.

Bai Jie really agreed, and sat in his place.

Yang Youxing hurriedly said at this time: "Sister Bai, there is a pumping machine on the side of the No. 6 machine well that has a little malfunction, I'll take a look, just put it in the document after you finish writing, they must be archived and kept for a long time." ”

Bai Jie was just about to write that the traversers were using a way of holding hostages to ensure that these pirate-born recruits would not have an accident, which fully showed that the traversers did not trust the Ming people, and they also shamelessly squeezed their labor...... But then I think about it, this is going to be archived, maybe people will see it later - forget it...... Different positions have different ideas, you see that although those Ming military families are tired, they also have a lot of rewards, and the smiles on their faces are also sincere......

Bai Jie shook her head and could only continue to write:

The military families of the Ming people still recognize labor very much, especially after Zhilu Dao gives his own army labor, and he is very motivated to work......

In the evening, Director Jianguo An was on night duty at the sugar cane field and could not come back.

Now the drought fight has reached a critical moment, which is the period of filling grain for various crops...... The machine well played a huge role, and the Ming farmers were also red-eyed, except for what cassava on the hillside, everything here has their seventy percent! Even the blind can see that this seventy percent can be several times more than in the past! No matter how hard and tired you are, you are not afraid...... Let's do it overnight.

Bai Jie naturally lived in Wu Yongmei's house.

"Have you?" Bai Jie asked in a low voice.

"Nope."

"Okay?"

"He's so tired for a while......"

"What about a while ago?"

"What are you doing...... I was busy processing alcohol a while ago. ”

"I don't believe you can't find the time......"

The two of them had a quarrel on the bed.

Due to the need to fight the drought, the power was cut off very early, and most of the people left behind, except for the guards, went to bed early. The traversers are also very hard.

Thanks to old friends Yezhongye, Melage, Drunk Not Messy Sex, Smiling Snow Wolf, and ZCF9527 for their support. Welcome new friends "forgot to buy tickets", your book review is too passionate...... There is nothing like it in the whole vertical and horizontal.
