Ammonia is also a toxic gas, and Leblasky and his men quickly put on gas masks. At this time www.biquge.info it is best for the worker to carry an oxygen cylinder on his back, and under the existing conditions, you can only expect the filter hanging under the mask to be of great use.

Yang Mingzhi did not leave an inch, keeping an eye on the work of the workers.

The critical ammonia purification has begun, and the toner is disposed of in a drum. After fully shaking and standing to precipitate, and then open the lid, what flows out is a clean liquid, but the smell is even more stinky!

Ammonia can be quickly mixed with water to form ammonia, and it can also react in reverse. In order to avoid the volatilization of ammonia as much as possible, clean ammonia water was put into a new tank.

The preparation of ammonium nitrate is already the final process, and Yang Mingzhi no longer has the heart to watch from a distance.

Putting on a gas mask, he also joined the busy team. It's just that he and the guards are not directly involved in the production, and they want to be urged by the overseers.

Ivanov, who was also wearing a mask, personally handled the final work and taught the workers the final operation by example. He noticed a crowd of people, one of whom was wearing a gold medallion that was unusually eye-catching.

"Comrade Deputy Division Commander! It's very dangerous here, you should stay away from here! Because of the mask, Ivanov's speech was very dull, which could not hide his inner worry.

Yang Mingzhi shook his head: "If it's really dangerous here, will you go into battle in person?!" ”

"But! You are the deputy division commander, you are the chief of staff, if there is an accident and you are injured, we ......"

"Shut up! Good work! Yang Mingzhi scolded: "There is no accident at all, compared to caring about me, you yourself are not fighting on the front line?" I'll show you a gesture now, I said that if you want to pinch the ammonium nitrate with your own hands, you must pinch it with your own hands! Now tell me, is it the final process? ”

Ivanov was overjoyed, he simply took off his mask, ignored the smell, 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, add nitric acid, and the final ammonium nitrate solution will be done quickly! ”

"What about time?"

Ivanov looked at his watch, it was already close to four o'clock in the afternoon. He shook his teeth and said, "The solution will be delivered at half past four at the earliest, and the solution will be precipitated neatly at five o'clock!" ”

"Then don't bother!" Yang Mingzhi also took off his mask and simply shouted at all the workers: "Comrades! It's the final battle! Mass production of fertilizers is starting today, and I want to give credit to all of you! All workers involved in the manufacture of fertilizers will receive medals! ”

Winning the honor is an excellent effort, and the workers have worked hard and started their work step by step.

……

In front of Yang Mingzhi was the second-largest stuffy tank in the fertilizer factory, and the materials were scarce and he could not afford to apply a layer of silver anticorrosive paint to it. It is a cast product, and the whole body is blackened, so to speak, this thing is a hundred-fold magnified version of the test flask.

Under Ivanov's direction, the entire stuffing process proceeded step by step, and when the last concentrated nitric acid was poured, the hatch lid was quickly closed and locked.

At the same time, it was as if a chain explosion had occurred in the tank, and a violent chemical reaction was taking place.

Yang Mingzhi subconsciously took a few steps back, and his actions also led the guards. Everyone was a soldier, and intuitively thought that this stuffy tank had become a huge bomb.

Ivanov and Leblasky remained unmoved, monitoring the pressure gauge motionless,

"Teacher! The pressure rises well, it's three atmospheres now! Leblaski reported truthfully.

"Watch out! Report values at any time! ”

After that, Ivanov wiped a handful of sweat from his forehead, he had already noticed that the chief and his party were retreating, so he waved and shouted: "Don't worry, the pressure is normal!" ”

As soon as he finished speaking, Leblasky reported a new situation, which was now four atmospheres.

Yang Mingzhi listened to it sincerely, the air pressure was four, and this stuffy tank should be able to deal with it. However, if there is any crack, when metal fatigue occurs, a tragic steam explosion will occur in the production process. The explosion in the fertilizer plant is often the cause of this kind of reason, and Yang Mingzhi couldn't help wiping a cold sweat.

Ivanov's confident face began to grow anxious, but fortunately he was still wearing a mask, and people could only watch the fat old pedant run to the pressure gauge and stare at it with his back hunched.

The pressure inside the tank began to drop rapidly as it approached five atmospheres.

Yang Mingzhi, who retreated into the distance, didn't know the specific events that happened in front of him, so he saw Ivanov sit down and lay flat on the ground.

"Oops! Something is wrong! Yang Mingzhi immediately rushed over and went to this guy's side, only to find that this old thing was actually laughing.

Asked about the situation, Rigushkov, who arrived in time, understood everything with just a slight glance at the pressure gauge: "Sir! The pressure starts to fall back and the reaction tends to stop and the important ammonium nitrate solution is complete. ”

"That's it? It's that simple? Regardless of Ivanov, Yang Mingzhi stared at the pressure gauge, and the pointer of this instrument was indeed moving slowly.

Leblasky leaned over with a look of relief and explained: "Sir! When the atmospheric pressure returns to normal, I'm going to open the floodgates, and 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, but it is like half a month.

If it weren't for the interference of fighting and rainfall, the fertilizer plant would have produced tons of ammonium nitrate by now!

Fortunately, there is no need to complain about anything now, because the pressure gauge shows that the pressure of the stuffy tank has returned to normal.

At this moment, Ivanov stood up again, and he made a request: "Comrade Deputy Division Commander, the coveted moment has finally arrived, and it is up to you to give the order to open the valve!" ”

"Good! It is an honor to witness this glorious occasion. With that, Yang Mingzhi turned around and ordered loudly: "Leblasky, open the valve!" ”

The workers were already ready, and the screw wrench of the pipe began to turn. At this moment, there is still a certain pressure in the stuffy tank, the valve cracks the gap, and the hot solution gushes out. Most of the heat during the chemical reaction is stored in the tank, so the high-temperature solution also makes it easy for workers to wait for it to cool down.

Yang Mingzhi is very aware of the high water absorption of ammonium nitrate, and it will not have any chemical reaction with the air, so what he has to do is really wait economically.

A large iron basin was half-buried in the ground, into which the solution was filled.

The temperature of the earth is still cool, so it begins to cool down rapidly. In order to ensure the rapid precipitation of ammonium nitrate, some specially prepared wooden strips are immersed in it.

Everything is going according to plan, ammonia is being produced continuously, and the iron barrels are being filled up quickly. And this first pool of solution has already been precipitated, and Yang Mingzhi can clearly see that white crystals have begun to attach to the wooden strips.

"Hey, hey! Look, sir, this is what you want! Ivanov picked up one, and at this moment the wooden bar had become a large "popsicle", but the white substance was ammonium nitrate crystals,

Sometimes, when the long-awaited thing is finally placed in front of oneself, people are not so excited, and they present a state of relief. Yang Mingzhi is exactly like this, as he said before, in front of the majority of onlookers, he detained these white crystals, pinched them into powder in his hands, and even licked them, and then made a painful expression.

"This thing is really miserable! It's ammonium nitrate! What I've always dreamed of is finally here! ”
