Yong Han and Fu Shuo came back from Shacheng. They were very tired. After two days of rest, they came back to work in the company. A phone call came and Yonghan came to the office.
Yan Zhuoshou said: "Abnormal noise and energy fluctuations were detected near the remote city recycling station. If you are free in the past two days, go take a look. Do you need anyone else to join you?"
"I'll go take a look first. It's okay."
Yonghan came to the recycling station, and Yan Zhuoshou said to meet with an agent here first to check why there were abnormal noises and energy fluctuations near the recycling station. The company is very large and its products include auto parts, transformers, electronic components, garbage disposals, etc.
Yonghan felt strange at first that he still had to work here.
There are several garbage mountains in the distance, and several garbage haulers are working. The garbage recycling station has organic area, electronic area, metal area, plastic area, glass area and so on. Organic matter can be returned to the ecological cycle through biological treatment methods. Metal, plastic, and glass can be recycled, re-sterilized, reshaped, and reused.
There is a place dealing with electronic waste, which has been called "one of the fastest growing solid wastes in the world", both in developed and developing countries. The growing amount of global electronic waste will increase the risk of heavy metal toxic materials such as lead, mercury, and cadmium entering soil and water sources, causing serious harm to the environment and human health. However, if it can be recycled, one ton of waste circuit boards can extract 400 grams of gold, 200 kilograms of copper and other precious metals.
Some use chemical methods to leach the crushed waste printed circuit board particles under acidic or alkaline conditions, and use methods such as solvent extraction, precipitation, replacement, ion exchange, filtration and distillation to separate the solution so that the required Metal precipitation and aggregation. Some use microbiological methods to select temperature and pH value. Some use disassembly and assembly methods to remove parts that can continue to be used.
Yonghan said to himself, "When making circuit boards, we use recyclable circuit boards, parts, and easily disassembled welding materials. It is also convenient to disassemble and recycle."
At this time, a worker from the recycling bin came and said, "Hello, who are you?"
"Workers from Landian Company, I heard there have been abnormal noises here recently and came to check the electrical equipment."
"Okay, welcome."
Then Yonghan continued: "It would be great if electronic components could be easily recycled."
"Many electronic components are made of silicon raw materials. The silicon raw materials need to be chemically purified. The shaping is done by melting the silicon raw materials, and then injecting the liquid silicon into a large high-temperature quartz container. Then, the raw materials are melted at high temperature. Then, the raw materials are rotated from the high-temperature container. The silicon raw material is taken out by stretching to produce a cylindrical silicon ingot. This cylindrical silicon ingot is sliced. Some substances are mixed into the new slices to make them into semiconductor materials. Then each slice is placed in a high-temperature furnace Medium heating, by controlling the heating time, a layer of silicon dioxide film is formed on the surface of the slice. A photosensitive layer is covered on the silicon dioxide layer. This layer of material has a good photosensitive effect when drying, and during the photolithography process After that, it can be chemically dissolved and removed."
"Yeah. I'm an employee of Landian Company. I'm here to meet someone. He's an agent. I don't know if he's here yet."
"I haven't come yet, I haven't seen it. I'm a staff member here, and there happens to be a broken processing device here. I don't know if you can repair it."
Next to the garbage transport machine, Yonghan found a damaged garbage disposal machine. After taking apart the casing, it turned out that garbage fell in and jammed the gears, and another gear was damaged. Yonghan confirmed that the machine had been shut down and the old gears had been removed and needed to be replaced with new ones.
It was a timing belt, and he chose the size and number of teeth for the large pulley.
This type of gear is very common. Looking at the garbage pile next to him, Yonghan thought, look around here, there are a lot of old machines here.
He took out the automatic guidance robot, scanned the gear pattern designed in the e-book, and then issued a search command. The self-guided robot entered the garbage area and started looking for gears.
Some time later, Zhen found one from an old transport plane. He went over and took it off with a wrench. Installed on the garbage disposal, it works again.
The worker next to him said, "Thank you, it's repaired."
"Yes, is there anyone else who would like to help? The company wants me to stay here for two days."
"There are also abnormal noises and energy fluctuations detected near the recycling station. See if there is anything you can do."
"The company manager also said so. I'll take a look around."
The worker said: "I'll give you the key to area 1. You can go to the management room of area 2 to get the other keys."
When Yonghan leaves Area 1, he needs to pass through Areas 2 and 3. When I was still in Area 2, I found that the doors on both sides were closed.
Yonghan said: "It seems that there are still some problems with the control system. It's not time to get off work yet."
He took out the camera robot, placed it next to the window, and went out through the gap in the window. Take out the drone and take off to take a look at the surrounding terrain. There is a bulldozer next to it, but the road is blocked and there is an excavator.
The battery of the camera robot is almost empty. He first controlled the drone to go to the battery recycling area to find a battery for it.
He remotely controlled the robot to come to the excavator, pushed the excavator's joystick, pushed away a pile of garbage, and cleared the path for the bulldozer.
The robot came to the bulldozer again and pushed the bulldozer's joystick. Push the garbage in front of you. The management room can be seen from the robot camera.
He controlled the robot to enter the management room from the ventilation duct and obtained the door key to Zone 2. After getting it back, Yonghan walked out of the gate of Area 2. Enter area 3 and see Meng Jianqi.
"What are you doing here?" Yonghan asked.
Meng Jianqi said: "Check out the group of car thieves. We chased them all the way and they are active around here."
Yonghan said: "What are they doing?"
Meng Jianqi said: "Looking for something. They searched all the way."
Yonghan said: "Are you sure what it is? I also saw them in Shacheng. It may be related to Tanshuizhu and Barbaric Snake."
Meng Jianqi said: "That must be related to what the wild snake can find."
Yonghan said: "The company asked me to come to meet someone, is it to meet you?"
Meng Jianqi said: "It should be so. Landian Company has also entrusted me to find out what is going on with the noise and energy waves here. I am a technical agent."
Yonghan said: "That means in addition to logical reasoning, you also have stronger technical skills?"
Meng Jianqi said: "It can be understood this way... I want to say that the car thieves you mentioned actually have a name. They are desolate people."
Yonghan said: "I didn't know there was such a name."
Meng Jianqi said: "Wilson and Kelin proposed a theory of the "broken window effect", which believes that if someone breaks the window glass of a building and the window is not repaired in time, others may With some demonstrative connivance, more windows are broken. Over time, these broken windows create a sense of disorder. As a result, in this disorderly atmosphere, crime will breed and flourish. And cars That's what thieves do, they want to break windows and create a shabby, smoky environment, create a desolate place, so they're called desolators. In their area, they have the fantasy of being able to run wild."
"'The window has been broken a long time ago, and what I did cannot play a key role' or 'I didn't do it first anyway', many people will argue like this. In fact, these arguments are simply untenable and wrong. If you are wrong, you are wrong, and other people's mistakes will not be the reason to prove that you are not wrong."
Yonghan said: "So the desolate people are causing trouble everywhere? They took away the water-detecting plants and the sound wave transmitters, and now they may be near this remote city."
Meng Jianqi said: "I'm not sure what it is. I need to secretly lure the snake out of the hole to see what they are looking for."
