Eight hundred and fortieth chapters the first ammonium nitrate
Ammonia is also a poisonous gas, so Lebraski and his guys also quickly put on gas masks. At this time, it is best for workers to carry oxygen bottles. Under the current conditions, everyone can only hope that the masks will
Hanging filters are of great use.
Yang Mingzhi stayed close to the work of the workers.
The very critical ammonia purification work has begun, and the toner is put into the iron bucket. After sufficient shaking and letting it settle, the lid is opened again, and what comes out is clean liquid, but the smell is even more stinky!
Ammonia gas can quickly mix with water to form ammonia water, and can also react in reverse. In order to avoid the volatilization of ammonia gas as much as possible, clean ammonia water is put into a new tank.
The preparation of ammonium nitrate was already in its final stages, and Yang Mingzhi no longer had the intention to watch from a distance.
Putting on a gas mask, he also joined the busy team. However, he and the guards were not directly involved in the production, but rather were urged by supervisors.
Ivanov, who also wore a mask, personally handled the final work and taught the workers the final operations by example. He suddenly noticed a group of people coming, and the gold medal worn by one of them was very eye-catching.
"Comrade Deputy Division Commander! It's very dangerous here, you should stay away from here!" Because of the mask, Ivanov's words were very dull, which could not hide his inner worry.
Yang Mingzhi shook his head: "If it was really dangerous here, would you go into battle yourself?!"
"But! You are the deputy division commander and chief of staff. If there is an accident and you are injured, we..."
"Shut up! Work hard!" Yang Mingzhi scolded: "There is no accident at all. Instead of caring about me, are you fighting on the front line? I will make it clear to you now. I said I would hold the ammonium nitrate with my own hands.
, you have to knead it with your own hands! Now tell me, is this the final process?"
Ivanov was overjoyed. He simply took off his mask, ignored the stench, and said excitedly: "Theoretically, the final chemical reaction will be very violent, but the reaction speed is extreme. We pour in a bucket of clean ammonia, and then
Add nitric acid and the final ammonium nitrate solution will be completed quickly!"
"Where's the time?"
Ivanov looked at his watch. It was now close to four o'clock in the afternoon. He shook his teeth and said: "The solution will be delivered at four-thirty at the earliest, and it will be neatly precipitated from the solution at five o'clock!"
"Then don't wait any longer!" Yang Mingzhi also took off his mask and shouted to all the workers: "Comrades! This is the final battle! Mass production of fertilizers started today, and I want to give credit to all of you! All of you!"
Workers involved in fertilizer manufacturing will receive medals!"
It is a great effort to receive an honor. The workers worked hard and started working step by step.
…
In front of Yang Mingzhi is the second largest stuffy tank in the fertilizer factory. Due to lack of supplies, there is no ability to apply a layer of silver anti-corrosion paint to it. It is a casting product and is completely black. It can be said that this thing is a hundred times larger than the test flask.
Version.
Under Ivanov's guidance, the entire filling process was carried out step by step. After the last concentrated nitric acid was poured, the hatch cover was quickly closed and locked.
At the same time, it was like a chain explosion had occurred inside the stuffy tank, and violent chemical reactions were taking place.
Yang Mingzhi subconsciously took a few steps back, and his actions also attracted the guards. They were all soldiers, and intuitively believed that the canister had become a huge bomb.
Ivanov and Lebraski remained unmoved, monitoring the pressure gauge motionless.
"Teacher! The pressure has risen well. It is now three atmospheres!" Lebrasky reported truthfully.
"Pay attention to monitoring! Report values at any time!"
After that, Ivanov wiped the sweat from his forehead. He had noticed that the chief and his party were retreating, so he waved and shouted: "Don't worry, everything is normal under pressure!"
As soon as he finished speaking, Lebrasky reported a new situation, which was now four atmospheres.
Yang Mingzhi heard it very clearly. At four pressures, this stuffy tank should be able to handle it. But if there are any cracks and metal fatigue occurs, a tragic steam explosion will occur during a certain production process. An explosion occurred in a fertilizer plant.
This is often the reason why things happen, and Yang Mingzhi couldn't help but wipe away a cold sweat.
Ivanov's confident face began to add anxiety. Fortunately, he was still wearing a mask. People could only watch this fat old scholar run to the pressure gauge and stare at it with his back hunched over.
The pressure inside the stuffy tank began to drop rapidly when it approached five atmospheres.
Yang Mingzhi, who retreated far away, was still unclear about the specific events that happened in front of him. He only saw Ivanov sitting down and actually lying flat on the ground.
"Oops! Something happened!" Yang Mingzhi immediately rushed over and reached this guy's side, only to find that the old man was actually laughing.
When asked about the situation, Liguschkov, who arrived in time, understood everything with just a glance at the pressure gauge: "Sir! The pressure has begun to fall, which means that the reaction tends to stop, and the important ammonium nitrate solution has been completed."
"Is it done? Is it that simple?" Regardless of Ivanov, Yang Mingzhi stared at the pressure gauge. The pointer of this instrument was indeed moving slowly.
Lebraski came over with a look of relief and explained: "Sir! When the normal atmospheric pressure returns, I will open the gate. As the temperature drops, the ammonium nitrate crystals you need will appear!"
The final wait is always painful. Although it may only be half an hour, it feels like half a month.
If it were not for the interference of fighting and rainfall, the fertilizer plant would have produced several tons of ammonium nitrate by now!
Fortunately, there is no need to complain about anything now, because the pressure gauge shows that the pressure in the stuffy tank has returned to normal.
At this moment, Ivanov stood up again and made a request: "Comrade Deputy Division Commander, the moment you have dreamed of has finally arrived. It is up to you to give the order to open the valve!"
"Okay! I'm honored to witness this glorious moment." After that, Yang Mingzhi turned around and ordered loudly: "Lebrasky, open the valve!"
The workers had already prepared, and the screw wrench of the pipe began to rotate. At this moment, there was still a certain pressure in the stuffy tank, the valve cracked the gap, and the hot solution spurted out. Most of the heat during the chemical reaction was stored in the tank, so the high temperature
The solution also allows workers to just wait for it to cool down.
Yang Mingzhi knew very well that ammonium nitrate was highly absorbent and would not react chemically with the air. All he had to do was to wait economically.
A large iron basin was half buried in the ground, and the solution was poured into it.
The temperature of the earth is still cold, so the solution begins to cool down rapidly. In order to ensure that ammonium nitrate is precipitated more quickly, some special wooden strips are prepared and immersed in it.
Everything was proceeding step by step, ammonia was being produced continuously, and the reserved iron barrels were being filled quickly. The solution in the first pool was already precipitating, and Yang Mingzhi could clearly see that white crystals had begun to adhere to the wooden strips.
"Hey! Look, sir, this is what you want!" Ivanov picked up a stick. At this moment, the wooden stick has become a large "popsicle", but the white substance is ammonium nitrate crystal.
Sometimes, when the long-awaited thing is finally placed in front of oneself, people are not so excited, and present a state of relief. Yang Mingzhi is exactly like this, as he said before, in front of the vast crowd of workers,
He picked off these white crystals, crushed them into powder in his hands, and even licked them, then made a painful expression.
"This thing is so painful! It is ammonium nitrate! The thing I dreamed of was finally produced!"
