Chapter 1310 Silver and Gelatin

Dr. Zhong took it over and took a look. Among them was electrolytic silver, a secondary control material—silver is not rare, but electrolytic silver is.The electrolysis industry of non-ferrous metals has not yet been developed, and this thing is used a little less.However, once the bayonet of the power industry is resolved, electrolytic copper and electrolytic silver will not be a problem.

The things below the list are more powerful.The things listed are all first-level control equipment and consumables, and it can be said that they cannot be self-produced within five to ten years.

According to the regulations, after he signs this type of professional material as a professional leader, unless the stock really reaches the "red warning line" standard, the Planning Institute will directly approve and receive it.In contrast, it seems to be a great responsibility.He read it several times, but he didn't dare to ask rashly: "These things really have to be used" or something like that: Dr. Zhong is basically at the same level as the naturalized people on the roadside in this specialty.If you talk too much, you will inevitably show your timidity.He thought about it, and felt that he still had to trust professionals. Besides, this project was indeed very important. Once it was successfully developed, it would no longer be a golden finger, but a black technology of the 17th century.

"I agree." Dr. Zhong took out his badges from his pocket and stamped them one by one in front of her, "Tomorrow I will hand it over to the secretary and send it to the Planning Institute—"

"If you don't think it's important, I plan to take these documents to the Planning Institute in person tomorrow—my time is too tight, and I can't wait to go through the official document procedure, and some things have to be selected by myself before I can rest assured."

"Alright." Zhong Lishi nodded, "But the procedures for your document are not complete. In this case, I will send you a note first. You go with the document and the note, and I will send someone to go through the formalities later."

"Then thank you very much." Ge Xinxin said generously.

Dr. Zhong took out the notepad on the letterhead of the Ministry of Science and Technology from his briefcase, took out the hero fountain pen and wrote it in a flying style, with a signature and date at the end.

Ge Xinxin took it and blew carefully, then smiled: "Thank you, you are really a good leader."

"You're welcome." Zhong Lishi stood up and said goodbye, "Once your project is successful, many people in the industry will be grateful for your kindness." He said jokingly
"That's not to be taken for granted. It's all the result of everyone's joint efforts." Ge Xinxin said, putting the document carefully in her pocket, "I'm going to do the experiment, please go slowly."

Ge Xinxin returned to her laboratory.Her two naturalized "apprentice experimenters" were still sitting on a bench in the corridor outside the door, waiting for her.Both of them are girls. In order to avoid troubles in daily work, Ge Xinxin chooses female experimenters, all of whom are over 1.60 meters tall—the experimental equipment in the laboratory is made according to the average height of veterans, which is too short It will be very laborious to use the naturalized civilians.

She unlocked the door with a key: her special laboratory number was four.It belongs to the "Special Laboratory", and most of the experimental equipment configured in it comes from another time and space.Entry and exit are strictly controlled.Except for the "apprentice experimenters" brought by the elders personally, the rest of the naturalized people are not allowed to enter.

Not only that, when the veterans are not present, the naturalized experimenters are also not allowed in--first of all, to ensure safety, the safety of the laboratory, even professionals in the 21st century will often make brutal mistakes, let alone this The natives of time and space.

A naturalized citizen who can be an "assistant" is one in a hundred, not to mention out of thousands.It is not as easy to make up for the dead and disabled as the loss of a laborer on the construction site.

Secondly, once an accident occurs, the equipment and medicines in the laboratory will be lost. Some of them are "more precious than gold"-there is no place to buy gold: the commonly used 1/1000 balance is not the current state of the Senate. industry can manufacture.

Ge Xinxin walked into the laboratory and checked the cleaning work done by the naturalized experimenters: sorting the waste liquid according to the label, washing the instruments, and tidying up the laboratory table.After confirming that everything was fine, he looked at his watch and said:
"You can get off work, and arrive at the laboratory on time at seven o'clock tomorrow morning——tomorrow you will work for Mr. Xu Yuan, and I have something to go out."

It's eleven o'clock in the evening—the naturalized experimenters don't have off-duty time, and they all get off work according to the veteran's schedule.When encountering a veteran like Ge Xinxin, basically there is only time left for sleeping, eating and going to the bathroom.

After letting the trainee experimenter leave, Ge Xinxin sat on the chair for a while—she was already very tired, and it could be said that she would fall asleep immediately when she lay down, but she still had to sort out her thoughts on applying for the project first.

Early the next morning, Ge Xinxin got up early, put on an empty backpack, took her usual handbag and set off.She got on Ma Niao's small commuter train all the way to Bairen, and then showed her ID at the ticket office of Bopu Station, and bought a ticket to Gaoshanling Station.

The track from Bairen to Gaoshanling has just been paved. Although everyone can take it, not everyone can buy the ticket to Gaoshanling Station at the terminal station: only the elders and naturalized people with special passes In order to buy a ticket for Gaoshanling Station.

Ge Xinxin came to the controlled material warehouse of the Planning Institute in Gaoshanling smoothly, and soon received the various controlled materials she applied for.

"Ge Xinxin, what are you doing with all this silver? And you need electrolytic sterling silver. No one is interested in this thing except those who are interested in electricity. There is also gelatin. Could it be that you want to make cold dishes or jelly? In the material office of the Planning Institute, Sun Xiao, who was on duty, asked strangely while stamping the application form Ge Xinxin handed over.

"Un secret qui rend une femme de femme." Ge Xinxin put her right index finger on her lips and said with a chuckle, then put the stamped application form in a binder and put it in her handbag, turned around and walked out of the office, only Leaving Sun Xiao staring blankly at the door and muttering to himself: "Huh? Is this perfume? Why is it two or three years old and still in stock? Who is this girl?"

With the gelatin and silver she had received, Ge Xinxin returned to her laboratory.She first took out a set of 24# distillation equipment-although it took a lot of effort, the glass factory can only manufacture 14# and above standard mouth instruments.Micro and semi-micro instruments are still "under development".But for today's work, the 24# equipment is just right.She poured a 500ml bottle of concentrated nitric acid into a 1000ml round bottom flask, added a few pieces of broken porcelain, and then distilled on an oil bath.Cutting the 115-125°C fraction is 68% concentrated nitric acid with most metal ions and other impurities removed.Add 100g of chopped sterling silver into the receiving bottle and change it to a water bath reflux device. Ge Xinxin then filled out an overnight reaction form and placed it in front of the device.He took off his white coat and hung it on the hook by the door.

She boarded the small commuter train from Ma Niao to Bairen City for dinner——tonight she planned to eat something good in a commercial restaurant to improve her life, and then went to the cooperative to buy some daily necessities, although the products there were far from her own The requirements are still far behind, and at any rate, many of them are barely usable.

At 95 o'clock in the evening, Ge Xinxin returned to the laboratory, stopped the reflux and transferred the solution to an ice bath to cool down.Turning on the water pump, there was a loud noise unique to this space-time machine, and she couldn't help frowning: "Really, the machinery factory has always said that it needs to be improved but has never acted." Pour the cooled reaction liquid and solids into the cloth lined with filter paper filter through a Schisner funnel, rinse with 5% ethanol 10 times, and drain.The obtained powder was collected in a brown jar labeled with silver nitrate, uncapped and placed in a desiccator.She then weighed 350g of gelatin and dissolved it in 32ml of hot water, added 55% recrystallized potassium bromide from horsetail and stirred evenly, keeping it at 40°C.Another 400g of silver nitrate was weighed and dissolved in 40ml of warm distilled water.Then she formulated [-]g of gelatin without excess water.

After all the solutions were prepared, Ge Xinxin turned off all the lights and drew the curtains—in the night when there was no light pollution in the 17th century, as long as the thick woolen curtains were drawn, it would be a perfect dark room.Turning on the flashlight covered with red paper, she started the next step.Slowly pour the silver nitrate solution into potassium bromide-gelatin, and keep stirring at 55°C for 10 minutes, then add the prepared gelatin, stir evenly and heat for half an hour.Ge Xinxin put the beaker into a light-tight box and covered it, then used a flashlight to find the light switch to turn on the light.She put a label on the box and put it in the cabinet, and then called the naturalized man on the night shift, and asked her to dispose of the waste liquid and clean the instruments according to the regulations.

"It's 10 o'clock, let's just finish this tonight." Looking at her watch, Ge Xinxin sighed.She left the laboratory and took care of the veteran experimenter on duty.Back to the dormitory building on the side.This building was specially built by the office for the veterans working in the central laboratory of heavy industry.Each has an office with sleeping quarters.This is much better than the treatment in the 21st century - as she and all chemical and chemical industry practitioners were used to, she only put a folding chair in the office
As one of the few female veterans in the laboratory, her dormitory has an independent bathroom.The dormitory is decorated in a feminine style, without any so-called "industrial" style.A small handmade pure wool Persian rug covers the bamboo floor.Hanging on the wall are fine brushwork flower and bird paintings bought during the booty auction, a table lamp transformed from a vase stands on the solid wood bedside table, and the single solid wood bed is covered with bedding made of white and blue calico—this is the most beautiful that the Ministry of Light Industry can produce Pure cotton bedding.The IKEA-style solid wood wardrobe made by the carpentry factory holds all kinds of her clothes, and a dozen bags and handbags are placed on the special shelf—a few of which are fake A-grade LV bags from the Lando ship. The paper wraps are placed on the top layer, and the rest are local products produced by the Ministry of Light Industry.
