Chapter 1277

Of course, Zhang Feng will not participate in the experiment.

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

In fact, there are two production methods of phosphate fertilizer.

One is acid dissolution, which is what Zhang Feng made now, and the other is thermal dissolution. This thing is to quench silica, dolomite and phosphorite at high temperature, that is, calcine like a kiln, and then extract the phosphorus powder from phosphorite, that is, after calcination, it is ground into phosphorus fertilizer.

Of course, these are also two kinds of fertilizer.

At this time, Zhang Feng has to calculate whether this acid dissolution method is fast or hot-melt type.

After all, if the toxin is dissolved by heat, it is too serious. Even with masks, the probability of pneumoconiosis and acute respiratory diseases of these workers will be greatly increased.

This is something Zhang Feng doesn't want to set foot in easily.

I don't want to get it out.

At least, he did not dare to get it out until the steam engine came out to replace man-made work.

At this time, under the guidance of Zhang Feng, Li Chengqian had a clear division of labor, and even could complete the experiment alone. With the protection of masks, at least Li Chengqian and others would no longer be poisoned by phosphorus.

However, when Shenshi's voice rang out, Zhang Feng had stopped everyone's experiment.

Li Chengqian and others were also attracted by this magical experiment. Even when Zhang Feng called, they didn't hurry for a while. Only then did they stop with interest.

As soon as they weighed, good guy, they almost startled Zhang Feng,.

From the beginning of the experiment to now, it is estimated that there are only two hours, but in these two hours, Li Qian and others have produced more than 50 kilograms of phosphate fertilizer.,

This made Zhang Feng feel incredible.

"Tut Tut, yes, you can make so much in two hours?"

"Hey, Feng Zi, if you don't stop, we'll probably drive several kilograms more!"

Chumo said with infinite dismay that he was about to take off his mask, but Zhang Feng stared back.

"It's good to get 50 Jin today, but I need you to get 50 Jin for me tomorrow. I believe it's not difficult?"

"No problem, why don't we continue now? It's still early!"

Chumo rubs his hands and gets excited.

A stone.

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

This is an achievement!

Think again, in the future, when these things can make food soar wildly, and all the people will remember their names, they will be even more restless.

But Zhang Feng hurriedly stopped and said, "now you know the benefits of this thing? Why didn't you have such passion before? If you had the general enthusiasm before, you would do a deeper experiment than this!"

！！！

As soon as Li Chengqian and others heard this, their ears stood up.

"What experiment?"

Zhang Feng turned his eyes and said, "now, wait for you. First give me all the common sense things! These things are confidential for the time being."

Hearing the speech, Li Chengqian and others couldn't sit still

When he was about to perform his massage plan, Zhang Feng hurriedly stopped and said, "OK, put away your set of handles, but if you use snacks, can you do this?"

"No, Fengzi, haven't we just touched some doorways?"

"Yes, isn't this the beauty of the taste? Can't you believe us? It's still early at the moment. We're making some. It's estimated that we can make 50 kilograms of phosphate powder today!"

Chumo is surrounded by Zhang Feng and is ready to continue the experiment.

Zhang Feng's head is still like a rattle.

"No, you can't say anything. The danger of this experiment can only allow you to end today's experiment. You must take two hours and rest two hours every day, otherwise you have been poisoned once. If you are poisoned, the gods will not save you!"

"I'm doing it for your good!"

“……”

Now, Li Chengqian and others no longer insist.

They haven't lived enough. Besides, they dare not touch the taste of vinegar for the rest of their life.

It's fucking sour.

Li Chengqian and others walked out of Chang'an University.

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

“……”

I still want to drink!

Several people couldn't help but collapse.

But a few people can't help it.

They don't want to do it again.

After parting from each other, Li Chengqian held a jar of vinegar and sat in a sedan chair drinking as he walked. He almost spit out his intestines.

But what can he do?

I have to take care of my life!

By the time Li Chengqian had returned to the Qianqing palace, doctor Zhou of the imperial hospital had already waited here early and had a good conversation with Hou Junji

They were surprised to see that Li Chengqian came in and there was a white thing hanging from his mouth.

"Your Highness, what's on your mouth?"
