Chapter 121 Synthetic Rubber and Plastics
The processing of rubber has been mentioned before, which is to wash it and cut it into small pieces.
Then heat it and add sulfur, zinc oxide, talcum powder and other mixtures, and finally mix and stir. If you are making a sealant, then you only need to stop at this step.
But now, Zhao Tianyang wants to make seals, so he has to add a molding step.
Finally, the obtained mold is vulcanized again to allow the rubber molecules to cross-link, thereby improving the strength, elasticity and heat resistance of the rubber.
The seal is then polished and trimmed to complete.
"Send these sealing rings and oil seals to Comrade Yu Xiaping."
Zhao Tianyang put the polished seals into a box and kept them well. After having Li Yuncai deliver them to the engine factory, he took out some materials and continued his work.
This time he wants to manufacture the lubricating oil needed for the gearbox.
The lubricating oil for the gearbox is different from the oil used in the engine.
In addition to lubricating, cooling, cleaning, sealing and rust prevention, engine oil also needs to cope with harsh working conditions such as high temperature, high pressure and high shear.
The lubricating oil for the gearbox is much simpler. It only needs to have good friction properties, withstand higher hydraulic pressure, and prevent foaming.
It is also relatively simple to manufacture, requiring only base oil (obtained using residual oil through vacuum distillation, solvent deasphalting and other steps).
Composite anti-rust and anti-oxidant (mixed with phenolic antioxidant, dimethylformamide, ethanol, diatomaceous earth, cellulose, acetic acid, etc.).
Extreme pressure agent (obtained by dehydration of vegetable oil, concentrated sulfuric acid and alkali).
Cleaning agent (mixed with kerosene, petroleum ether, emulsifier, surfactant and deionized water).
Dispersant (obtained by mixing and melting sodium carbonate and quartz sand).
Metal passivator (obtained by mixing, stirring, filtering and purifying phosphoric acid, zinc oxide, deionized water, etc.)
Viscosity modifier (obtained by mixing, heating and filtering methacrylate monomer, benzoyl oxide, toluene, etc.)
Mix the above substances and filter them to get transmission oil.
But some things are easier said than done, and Zhao Tianyang did not have any of the above-mentioned materials.
In order to obtain these substances, he had to synthesize them one by one and create various experimental instruments.
"Oh shit!"
Finally, when I was synthesizing phenolic antioxidants, I accidentally added too much ethanol and made myself dizzy.
Zhao Tianyang threw away his mask in despair, walked out of the tent and prepared to take a breath first.
"Chief, calm down. It's normal to have successes and failures when doing experiments. Come and have a cigarette and take a break!"
At this time Li Yuncai, who had been assisting Zhao Tianyang in the experiment, came out, handed him a cigarette with a smile, and persuaded him.
“Shh… huh…”
After lighting the cigarette and taking a puff, Zhao Tianyang pondered for a moment and said, "Record it."
"Yes."
Li Yuncai quickly took out a notebook and pencil and looked at Zhao Tianyang.
"Huangyadong Arsenal requests various petroleum products, such as gasoline, diesel, kerosene, lubricants, asphalt, etc. In short, anything related to petroleum."
"Secondly, I suggest that Yan'an build a plastics factory and a synthetic rubber factory next to the oil refinery to research and produce various plastic and rubber products!"
"I'll give you the rubber and plastic processes and technology tomorrow!"
"Yes!"
Li Yuncai nodded and wrote down what Zhao Tianyang had just said.
"Huh... let's go, keep going!"
Zhao Tianyang threw away the cigarette butt and walked into the tent again.
Although he could wait for the lubricant to be delivered from Yan'an, he still had to wait. He had already started doing it, so he might as well get the lubricant out first!
...............
At night, after eating in the cafeteria, Zhao Tianyang returned to his sleeping tent and began to write the processes and specifications of plastics and synthetic rubber.
Plastics are made from naphtha, a petroleum product, through "steam cracking".
Synthetic rubber is obtained by heating a mixture of liquid butadiene from petroleum and a hexane solvent.
The next morning, Zhao Tianyang handed the results of his hard work all night to Li Yuncai.
Ask him to send what he said yesterday, as well as the rubber, plastic technology and specifications to the headquarters, and then have the headquarters hand it over to Yan'an.
It is worth noting here that due to rubber and plastic technology, these messages cannot be sent via radio.
Someone must be sent from headquarters to escort it, so it may take half a month to get a reply.
On April 1938, 4, the hydroelectric power station was completed and the assembled turbine generator was carried into the machine room.
"I declare the ribbon-cutting ceremony of the Huangyadong Hydropower Station over!"
As Zhao Tianyang finished speaking, Cheng Mingsheng personally entered the machine room and started the water truck door.
Suddenly, the turbine rotated and drove the generator, and the lights in the engine room suddenly lit up.
Then Cheng Mingsheng came to the switch and lifted it. A trace of electricity flowed into various factories and dormitories along the wires that had been moved long ago.
“Oh oh oh….”
“There’s electricity!!”
The workers present were very happy.
Although the factory has had electricity for a long time, it is also something to be happy about that the workers’ dormitories can now have electricity!
While everyone was happy, Zhao Tianyang announced without spoiling the fun that today was a holiday and everyone was ordered to go up the mountain and farm.
"Ah! I thought a holiday meant a day of fun!"
"What are you playing for? If you don't farm, what will you eat and drink?"
Li Yuncai shouted to the people standing in the crowd: "Hurry up, everyone move."
"Today we are going to plant crops on the land we reclaimed last time and the land we reclaimed recently."
"Oh!!"
Although the responses were weak, everyone quickly collected farm tools from the warehouse and followed Li Yuncai and other managers up the mountain.
“How much electricity can this hydroelectric power station generate?”
On the way up the mountain, Zhao Tianyang asked Cheng Mingsheng beside him.
"After calculation, the motor efficiency can reach 70%, and the maximum power generation should be 130 kilowatts."
Cheng Mingsheng answered without hesitation.
"Well, that's enough!"
Zhao Tianyang nodded with satisfaction. His Huangyadong Arsenal was only this big, and 130 kilowatts of electricity was more than enough.
Including the five acres of land reclaimed last time, plus the ten acres of land reclaimed by the workers' families in the past month, more than 800 soldiers and workers finished all the work in less than two hours.
"That's sloppy!"
"Continue to cultivate the land, and plant while cultivating the land!"
At the edge of the field, Zhao Tianyang looked at the workers around him who were not even sweating, and gave orders helplessly.
"Yes!"
Next, the workers reclaimed one acre of land and planted one acre of grain. At the end of the day, they had reclaimed a hundred acres of land.
"Alright, that's enough. Thank you for your hard work. Let's stop here for today!"
Zhao Tianyang looked at the sky, wiped the sweat from his head, and told Li Yuncai: "Notify the kitchen to have noodles tonight."
"Oh! Long live the Section Chief!"
"Let's eat noodles!"
When the workers heard that they would have noodles to eat, they immediately forgot about their tiredness from a day's work and all of them started to smile happily.
