Although Feng Nuo was not satisfied with the fact that the machinery factory only hired one new worker who had just graduated from a vocational school and entered the factory, it was better than nothing. To actually trial-produce relays, there is much more trivial work than the "design" that was discussed before, and these tasks do not require skilled technicians. Having a helper can free up a lot of your energy. He was planning the progress in his mind, and he didn't notice that the young man in front of him occasionally glanced in the direction of his office.
Feng Nuo spent the past two days studying the enameled wire manufacturing materials given by Faraday without eating or sleeping. Generally speaking, Faraday has also tried to produce enameled wire, and the route is quite complicated. There are modified tung oil and modified raw lacquer. No matter which one is used, the wear resistance of the paint film is very poor, and it must be wrapped with cotton yarn. Reinforcement. It can barely be used on motors - the disadvantage is naturally that it affects the service life.
"It seems like it's not too difficult." Feng Nuo read the information and felt that he was still confident that he could do it.
The power outlet also generously gave him a part of silicon steel sheets that were said to be of good quality. This was like stepping into the relay manufacturing pit. Hearing that he was interested in this business, senior power companies and seniors interested in electronics sent letters and calls to offer advice. For a time, Feng Nuo's residence and office were filled with people, and his motivation increased a little.
Once he got involved in the project, he learned that there were people in Laigao doing things like enameled wire, but that was another research direction. The name of the project was "Electronic Components Development Group", and the host was his colleague Xiu Yuxuan.
Xiu Yuxuan originally had a background in communications engineering. Since landing, his main job has been to maintain the computer room of Lingao Telecom. Although the work location is different, the work is basically the same.
Seeing that there was really no future in the computer room maintenance job, Xiu Yuxuan followed Zhong Lizhi's path and entered the "Institute of Electronics" under the Ministry of Science and Technology as the director - of course, the polished commander.
Xiu Yuxuan is busy "restoring" various electronic components at the Institute of Electronics. Speaking of which, manufacturing electronic components is not difficult. The difficulty is that the raw materials rely heavily on fine chemicals, so Director Xiu's work is not smooth.
Now I heard that someone wanted to gnaw on the bones of the relay. Director Xiu not only visited him personally, but also exchanged his experience on running projects and maintaining the computer room. Finally, he gave him a set of technical information that he specially collected from the big library.
After sending Xiu Yuxuan away, he casually opened the folder Xiu Yuxuan sent him. The first one was a mimeographed booklet "Enameled Wire Simple Manufacturing Method". There is also a line below: Internal readings of the Ministry of Science and Technology, please save them.
Looking at the title of the pamphlet, Feng Nuo felt a murmur in his heart. Opening the preface, although many contemporary words have been removed, the familiar writing style still made Feng Nuo immediately understand that this was a so-called "made by local method" pamphlet compiled and published during the Great Leap Forward.
Feng Nuo's eyelids jumped again. In the past two years, the Manufacturing Directorate and the Planning Institute have issued multiple documents to various departments, specifically requesting the industrial, scientific and technological, and military technology research and development groups to be careful in using the "Great Leap Forward" and even "pre-liberation" Native method, simple method”. Pay attention to standardization issues and eliminate outdated technologies. In particular, it is pointed out that the use of such indigenous methods must be done in small batches first, and cannot be blindly put into large-scale production.
But for him, a 100% layman, this type of booklet is easier to understand and experiment with.
"Forget it, we'll keep it simple because it's crude. We Lingao didn't start with the imitation of local methods. Why should our project be in line with the old time and space standards from the beginning?" Feng Nuo thought to himself.
"The entire production process of enameled wire includes several processes of drawing, painting, baking and winding. Special enameled wire coating is applied to clean bare copper wires. After baking at a high temperature of 300-400 degrees Celsius, the coating is tightly aggregated. The ground is wrapped on the line and then cooled to become an enameled wire. This is a continuous production process. During the production process of a whole enameled wire, each part goes through each process one by one without stopping."
This book seems to be quite reliable, and it is written quite clearly. It also honestly tells who was consulted and which factories were consulted for their craftsmanship. A table in the book also records the number of paint layers and the number of paint layers under each wire diameter. The thickness and room temperature resistivity are all extracted from industrial data of the former Soviet Union.
According to the record of this simple method, the equipment for boiling insulating paint is extremely simple: basically a stove and a pot. Of course, this pot is specially made. The pot lid is equipped with a flue, and is also equipped with a thermometer, stirring rod and Grignard tube. , the stirring rod can be extended through a small door on the pot lid. Grignard tubes are used to measure paint viscosity. The smaller the wire diameter, the lower the paint viscosity should be.
He looked at the equipment and tools listed in the brochure, and there seemed to be nothing that Lingao couldn't make.
The formula of the insulating paint is 17% phenolic resin, 43% raw tung oil, 0.35% lead oxide, 0.1% cobalt desiccant, and 40% lamp kerosene. Seeing this, Feng Nuo breathed a sigh of relief. Lingao could produce these raw materials by itself. He didn't know if there was phenolic resin, but in middle school chemistry class, synthesizing phenolic resin was the simplest organic experiment. As for the raw materials phenol and formaldehyde, Lingao's chemical plants are manufacturing them; not to mention tung oil, this is China's traditional bulk export trade commodity and is also widely used by the private sector. Even in the industrial system of the Senate, it also plays an important role. Role; Lead oxide has been around since ancient times, the so-called Mitra monk. This is a by-product of alchemy, a product of the sulfide-like galena group mineral galena deposited on the bottom of the furnace when silver and lead are refined. It is a very important Chinese medicinal material. It was also used as a whitening agent in ancient cosmetics. It is not difficult to prepare directly; kerosene is certainly available; only cobalt desiccant is left. The preparation method is also introduced in the information, and it is mentioned that manganese desiccant made from manganese dioxide can also be substituted. There are manganese ores under the control of the Senate. Come to think of it It’s not a problem either…
Feng Nuo felt more and more that this information was good. There was also a basic design of the enameling machine. Some of the substitutions were made by local methods, such as replacing the steel of the frame with bricks/wood, replacing the painting wheel with multi-groove porcelain insulators, and using waste materials to make the oven. Etc., there is no need to follow the same pattern in Lingao. All-steel equipment and necessary ceramic components can be produced by ourselves.
More importantly, the empirical data in the data are relatively complete, such as the boiling temperature range, the drying temperature range, the distance between the wire and the furnace wall, the amount of desiccant, the line speed of the painting process, and the amount of felt used for polishing. The thickness has empirical values. Even the preparation of acids and alkalis used in ventilation equipment, copper wire drawing and cleaning equipment are also introduced, but Feng Nuo does not need to consider these. At least he plans to rely entirely on the standard parts factory for wire rods, and the basic facilities of the factory are also ready. The acid and alkali are directly withdrawn from the planning institute's warehouse.
Finally, Feng Nuo wrote down the finished product specifications and quality inspection methods recorded in the materials. Since it was to be done, the specifications and quality that could be achieved by the native methods of the Great Leap Forward period were the minimum requirements.
In the next few days, Qian Yuzhi was ordered by Feng Nuo to move around. Not only did he carry various raw materials here and there, he also had to test the insulating paint according to the formula without any protective measures every day.
Although the lacquer boiling pot has been ordered, because it is a special product, it requires a certain manufacturing period. So what Feng Nuo gave him was really an ordinary iron pot, not even as good as the pot with a flue and stirring port on the lid in the Great Leap Forward brochure.
The cooking temperature is as high as more than 200 degrees, and the drying temperature is 300 to 400 degrees. The smell is even more touching. Naturally, there are no gas masks, not to mention 3m masks. The only labor protection Qian Yuzhi can get is a 24-layer gauze mask produced by Lingao and a pair of bulky labor protection glasses.
In order to prevent him from being burned, he wore thick work clothes while boiling the paint. Within a few hours, the clothes looked like they had been fished out of the water.
Because the pot is directly heated, temperature control is very difficult. Overheating often occurs. Once the raw materials are scrapped, not only will the hard work for several hours be in vain, but the commander's face will also become very ugly.
Qian Yuzhi was sweating profusely and dizzy from the heat every day. When he got home, he would collapse on the bed like a dead dog, completely forgetting that there was a beautiful girl wearing a liberal arts college uniform living in the attic.
Listening to Qian Yuzhi's snoring downstairs, Li Janai couldn't sleep at all. It wasn't because he snored - she had something on her mind.
In the darkness, she stared at the beams under the roof with her eyes wide open - she had cut off contact with the "organization" for several months.
This was something that had never happened to her since she entered the Lingao quarantine camp three years ago. It seemed like a heavy stone was pressing on her heart, and it was like there was a cold gap in her heart. She couldn't help shivering, shrank her body towards the corner again, and wrapped the blanket tightly around her.
When she was in the quarantine camp, she was an orphan and was born thin, so she was promoted to a "monitor" in the quarantine camp and spent several more periods of quarantine. It was not until her body growth accelerated a year later that she was released. Due to her good performance in surveillance work and good figure and appearance, she was then assigned to a maid school and was officially developed into a "hidden agent" of the General Administration of Political Security. Over the past two years, she gradually accepted many secrets training, and continued to work as internal security in the maid school and the restructured liberal arts college.
When she graduated, the "organization" informed her that a new "superior" would assign tasks to her when she was assigned to a job.
However, this was her last contact with the "organization".
As time went by, Li Janai became more and more nervous. During the training, the instructor said that he would be given clear instructions if he lurks for a long time or retires. If he fails to contact the contact person within the time limit, he will be treated as a traitor. However, no one has contacted her in the few months since she joined the Tiandi Society. According to discipline, she cannot take the initiative to contact her previous contacts. Now she doesn't know what is wrong with her situation. The loneliness of being "abandoned" by the organization and the panic of being "dealt with" by the organization are gradually eating away at her spirit.
