Chapter 1176

Zhang Feng of course will not participate in the experiment.

After all, when these people are doing experiments and instructing, he still needs to study the things after extraction. Although the phosphorus element is easy to extract, this phosphate fertilizer is somewhat difficult.

Actually, there are two production methods for phosphate fertilizer.

One is acid dissolution, which is what Zhang Feng does now, and the other is thermal dissolution. This thing is to use silica, dolomite, and phosphorite together with high temperature tempering, which is Like a kiln, go to Calcinate, and then extract the phosphorous powder from the phosphate rock, which is the phosphate fertilizer after the calcinate is ground.

Of course these are also two kinds of fertilizers.

At this time, what Zhang Feng wants to calculate is whether this acid dissolves faster or the hot melt faster.

After all, if heat dissolves, the toxin is too serious. Even with masks, the probability of these workers getting pneumoconiosis and acute respiratory diseases will greatly increase.

This is Zhang Feng's reluctance to get involved easily.

I don't want to get it out.

At the very least, he wouldn't dare to make it out before the steam engine came out to replace humans.

At this time, under the guidance of Zhang Feng, Li Chengqian and the others have a clear division of labor and can even complete the experiment individually. Coupled with the protection of masks, at least Li Chengqian and the others will never again. Phosphorus is poisoned.

However, when Shen Shi's voice sounded louder, Zhang Feng had already stopped everyone's experiment.

Li Chengqian and the others were also attracted by this kind of magical experiment. Even when Zhang Feng called them, they didn't have to rush for a while, and then they stopped in despair.

Everyone weighed in, good fellow, almost surprised Zhang Feng.

From the beginning of the experiment to now, it is estimated that there are only two hours, but within these two hours, Li Qian and the others have actually produced more than fifty catties of phosphate fertilizer. ,

This makes Zhang Feng a little bit unbelievable.

"tsk tsk, you guys, can you make so much in two hours?"

"hehe, Feng'zi, if you don’t stop calling, We estimate that we will be driving a few more catties!"

Cheng Chumo said infinitely, while speaking, he was about to take off his mask, but Zhang Feng glared back.

"I can make fifty catties today, which is good, but tomorrow I need you to make fifty catties for me. I believe this is not difficult, right?"

"No problem, or, shall we continue now? It's still early!" Cheng Chumo rubbed his hands, a little excited.

A stone.

Through their hands, with the help of a lamp, without the effort of a meal, they can become a pile of things thinner and whiter than salt. What is this? ?

This is an achievement!

Think again, when these things will make food soar in the future, and all the people will remember their names, they will be even more unable to sit still.

But Zhang Feng hurriedly stopped and said: "Now you know the benefits of this thing? There was no such passion before, but if you had the same passion before, you will do the same. A more profound experiment than this!"

! ! !

When Li Chengqian and the others heard it, their ears stood up.

"What's the experiment?"

Zhang Feng rolled the eyes and said: "Now, wait for you to understand all the common sense things for me first! Let's talk about these things for the time being , Confidential."

hearing this, Li Chengqian and the others could not sit still. ,

When he was about to perform his massage plan, Zhang Feng hurriedly called to a halt: "Okay, put away your set, but if you use snacks, can you do this?"

"No way, Feng'zi, haven't we just touched the doorway?"

"Yes, isn't this the beauty of rigid body taste? We can't you believe it? It’s too early at the moment, and we’re making a little bit. It’s estimated that we can make 50 catties of phosphorous powder today!"

Cheng Chumo surrounded Zhang Feng and prepared to continue the experiment.

Zhang Feng is still swinging his head like a rattle.

"No, you can’t say anything. The danger of this experiment can only allow you to end today’s experiment. You have to get two hours each day and rest two hours. , Otherwise you are the ones who have been poisoned once. If you are poisoned, Daoist Immortal will not be able to save you if it comes!"

"I am doing it for your good!"

"..."

Now, Li Chengqian and the others no longer insist.

They haven't lived enough yet, besides, the smell of vinegar, they dare not touch it for the rest of their lives.

Too fucking sour.

Li Chengqian and the others walked out of Cháng'ān University in anguish.

But at this moment, when Zhang Feng stepped into the sedan chair, he said: "Remember, a jar of vinegar every day is indispensable!"

"..."

I still want to drink it!

Several people couldn't help but collapse.

However, a few people can't help it.

The uncomfortable feeling before, they don't want to do it again.

After the separation, Li Chengqian held a jar of vinegar and drank while sitting in the sedan chair. He almost vomited his intestines when he drank it.

But what can he do?

This fate has to be taken care of!

When Li Chengqian had returned to the Palace of the Qing Dynasty, Zhou imperial physician of the imperial physician hospital had already waited here early and had a very happy conversation with Hou Junji. ,

When Li Chengqian entered the door, and there was still a white thing hanging on his mouth, the two could not help being shocked.

"His Royal Highness, what is on your lips?"
