After returning from the electrical equipment factory, Zhang Yunfei started to build an early warning radar station. Now that there is an early warning radar, Zhang Yunfei plans to choose a few suitable places in the Datong base area, and build several radar stations as soon as possible, so that as long as the little devil's plane is about to enter the base area , can be detected by radar immediately.

Originally, Zhang Yunfei wanted to build a vehicle mobile radar station, but he immediately rejected this idea. First, the radar needs 24 hours, that is, it needs to work around the clock, which means that it needs 24 hours of power supply; second, there are not so many small ones in the current base Diesel or gasoline generator.The establishment of the vehicle mobile radar station can only be carried out later.

Therefore, we had no choice but to choose a suitable place to build a fixed secret radar station. At present, the early warning radar is a secret weapon and has not yet been released to the world. Secret Radar Station. [

After the radar station is built, wires and telephone lines need to be connected, and special radar operators and a certain number of security personnel need to be stationed.

Now, telephones are relatively popular in Datong. The troops have telephone connections in general camps above the battalion, and the factories and several nearby counties have also connected telephone lines.

With the cooperation of radar experts, Zhang Yunfei quickly selected the location. In the next month, these radar stations will be completed and put into use. For the sake of confidentiality, Zhang Yunfei did not use free Japanese labor for the construction of the radar station. It is to mobilize thousands of soldiers to serve as construction workers.

In the next few days, the situation in Datong was calm, and the fear that the little devils would attack the base area in retaliation because their lieutenant general was killed did not appear.

But before Zhang Yunfei could relax for a few days, Fang Zheng, the political commissar in charge of logistics and base construction, approached Zhang Yunfei with a sad face, and said to Zhang Yunfei, "Master, our car production has encountered difficulties."

Hearing what the political commissar said, Zhang Yunfei felt his heart skip a beat, and immediately asked with concern: "Political commissar, what problem have you encountered?"

Hearing what the teacher said, Fangzheng knew that he was in a hurry and didn't explain the problem clearly, so he immediately said: "Our automobile factory has been progressing smoothly. Several Jewish experts used to be senior experts from the German Mercedes-Benz company, but today the tire The workshop told me that our rubber reserves are seriously insufficient, there are only a few tens of tons in stock, and it will be used up in a few months."

"We used to smuggle from foreign companies in Guangzhou at high prices, but now that the little devils are attacking Guangzhou and Hong Kong, our smuggling channels will be cut off in the future, and our car factory will be cut off a few times after it goes into production because there are no tires. It will be discontinued in a month."

After hearing what the political commissar said, Zhang Yunfei also paid attention to it. If this is the case, it will be a tragedy. The car factory he has worked so hard to build will stop production immediately because there is no rubber.

It’s not that Zhang Yunfei hadn’t considered the issue of resources before. Although Datong is deep inland, there are steel, coal, and oil found here. The major resources are basically complete, and the demand for other things is also small, and they can be purchased one after another. Production started.

But Zhang Yunfei ignored the rubber as an important strategic material. The British foreign company contacted Guangzhou two months ago. Although the price was nearly [-]% higher than the market price, the foreign company was responsible for delivering the goods to Shanxi. Enough, I didn't expect to buy dozens of tons in two or three months.

What is the concept of dozens of tons of rubber?Dozens of tons of rubber can only be used to produce a few hundred cars, and it will be consumed. According to the monthly output of two to three hundred cars, the rubber will run out in less than two months.

Zhang Yunfei walked around in the office, his brain running at high speed, mobilizing all his knowledge, and thinking hard.

Fang Zheng, the political commissar, saw that Zhang Yunfei was thinking carefully about the problem, so he stood aside silently to prevent disrupting Zhang Yunfei's thinking.

After thinking for more than ten minutes, Zhang Yunfei suddenly had a flash of inspiration, and a word flashed in Zhang Yunfei's mind, synthetic rubber, yes, it is synthetic rubber.

Thinking of this, Zhang Yunfei let out a long breath, and slowly let go of his high-hanging heart, and a smile began to appear on his face.

Seeing that Zhang Yunfei's face turned from cloudy to sunny, political commissar Fangzheng asked cautiously: "Master, is there a solution?"

"Well, there is a way." Zhang Yunfei nodded affirmatively.

"That's great, sir, what good idea have you thought of." [

"We can synthesize rubber, but we don't know if there are any talents in this field." Zhang Yunfei said.

"Can this rubber also be synthesized?" Fangzheng asked doubtfully.

Seeing the doubts of political commissar Fang Zheng, Zhang Yunfei sorted out the knowledge in his mind, and began to popularize rubber knowledge to Fang Zheng.

Rubber is a necessary material for the manufacture of aircraft, warships, automobiles, tractors, harvesters, irrigation and drainage machinery, medical equipment, etc.According to different sources, rubber can be divided into natural rubber and synthetic rubber.

Synthetic rubber began to be produced at the beginning of this century. During the First World War, Germany was forced to use dimethyl butadiene to polymerize methyl rubber due to lack of rubber plaque.

Synthetic rubber is generally not as comprehensive as natural rubber in terms of performance, but it has high elasticity, insulation, air tightness, oil resistance, high temperature or low temperature resistance, etc., so it is widely used industry, defense and transportation.

And synthetic rubber is cheap and can be produced in large quantities. During World War I, Germany produced about 2500 tons of methyl rubber.

Around 1930, Germany and the Soviet Union used butadiene as a monomer and metal sodium as a catalyst to synthesize a rubber called butadiene.At present, the German and Soviet armies are widely used Buna rubber.

The principle of synthetic rubber is not very complicated. Although I don't understand the specific process of synthesis, I guess it should not be difficult. Rubber has been synthesized decades ago in foreign countries.

I was in a hurry just now, and after thinking about it for a long time, I remembered that there are already synthetic rubbers abroad, and there are several varieties of synthetic rubbers abroad.

Hearing Zhang Yunfei's eloquent speech, Fangzheng was filled with admiration. He thought that the master's knowledge is so rich. After Zhang Yunfei finished speaking, Fangzheng said with admiration: "Master, you are really amazing, you know so much."

Zhang Yunfei smiled embarrassedly, and then said cheekily: "Hehe, I read them all from books, including a lot of other knowledge, I read them from books when I have time."

Zhang Yunfei paused, then said to Fang Zheng, the political commissar: "So, if we want to successfully produce synthetic rubber, we must first find someone who understands synthetic technology. However, our base area is full of talented people, and I believe we can find talents in this field. I will entrust you with the task of finding someone.”

"Teacher, don't worry, I promise to find talents in this field, just wait for my good news."

"Okay, I'm looking forward to the good news." Zhang Yunfei also said happily.

In less than two days, Fangzheng found a German Jew. This Jew had been engaged in research on synthetic rubber, but that was two or three years ago. Since the Jews began to be persecuted, the research was interrupted.

Zhang Yunfei was well aware of the love of money and greed of the Jews, as long as they had enough money, they were willing to do anything, so Zhang Yunfei promised on the spot that as long as the Jew could mass-produce rubber, he would be rewarded with five thousand oceans.

Hearing that there was a reward of [-] oceans, the Jew's eyes lit up immediately, and he happily patted his chest to promise that he would make rubber as soon as possible.

To be on the safe side, Zhang Yunfei specially selected a few people who knew chemistry to form a research team with the Jew, and specially allocated [-] oceans as research funding.

And it is planned to build a synthetic rubber factory in the southern suburbs of Datong, near the oil refinery, so as to produce urgently needed rubber at the fastest speed.
