industry is king

() "It is feasible. If I remember correctly, the ratio of nutrient content is nitrogen, phosphorus pentoxide, and potassium oxide [-] to [-] to [-]." Fu Xin answered straightforwardly without any detours or tricks. .

"What about the ratio with lower nitrogen content?" Fu Zhenbang touched the corner of his mouth and asked in thought.

"The ones with lower nitrogen content...let me think about it..." After finishing speaking, Fu Xin rubbed his temples. He really doesn't remember this question clearly. In his previous life, he only had a little contact with the chemical fertilizer industry. , not very well understood.

After thinking for a while, Fu Xin patted his forehead suddenly and said, "Oh... yes! Sorry, I misremembered, there should be four types of nitrophosphate fertilizer recorded in the notebook, namely potassium sulfate type, high Nitrogen type, balanced type, high nitrogen and high potassium type, there is no low nitrogen type, sorry!"

"Then what do you remember exactly?" Fu Zhenbang said impatiently, fed up with Fu Xin's words like squeezing toothpaste.

"I remember very clearly that it is the balanced type, but the balanced type can definitely solve the current problem!" Fu Zhenbang said embarrassedly. In fact, as an academician in his previous life, he can only come here to give an overview. It's aggrieved!

"Then quickly tell me how to make balanced nitrophosphate fertilizer, don't make these useless!" This is also Fu Zhenbang, this is Fu Xin's old man, if it were someone else, he would never dare to say that. People, who doesn't treat the truly knowledgeable people as uncles!

"Okay, I'm sure I'm not wrong with this preparation method. First, use 58% to 60% nitric acid to decompose phosphate rock in the acidolysis tank. The acid solution goes through the precipitation tank and washing drum to remove the acid insoluble matter. , and then in the partition cooling crystallizer, use ammonia gasification or brine as the freezing medium..."

Before Fu Xin finished speaking, he was interrupted by Fu Zhenbang, who asked, "Wait, is the salt water you're talking about edible salt water or industrial salt water?"

This edible salt refers to processed edible salt with sodium chloride as the main component obtained from seawater, underground rock (mine) salt deposits, and natural brine (salt) water, excluding low-sodium salt.

The main component of edible salt is sodium chloride, and it also contains a small amount of water, impurities, and other elements such as iron, phosphorus, and iodine.

Industrial salt, in fact, is mainly "sodium chloride", which is widely used in industry and is one of the most basic raw materials in the chemical industry, known as the "mother of the chemical industry".

Among the main products of the basic chemical industry, hydrochloric acid, caustic soda, soda ash, ammonium chloride, and chlorine gas are mainly produced from industrial salt.Sodium chloride is required in large quantities in the organic synthesis industry.

In addition, industrial salt is also used in soap manufacturing, ceramics, glass production, daily chemical industry, oil drilling, drilling fluid, completion fluid, petrochemical dehydration fluid, early strength agent in the construction industry, coagulant in the production of coatings, rubber industry ru Gelling agent, paper industry additives and deinking of waste paper, inorganic chemical raw materials and sulfate radical removal agent in chemical industry, coagulant of sodium alginate, prevention and treatment of wheat, apple, cabbage and other rot and food preservatives, production of metal Sodium and other sodium compounds, steel heat treatment media, etc.

In addition, industrial salt is also widely used in water treatment, road snow removal, refrigeration and refrigeration.

There is also a saying that industrial salt is sulfate and nitrate, and industrial salt cannot be eaten, otherwise it will cause food poisoning.

"It's industrial salt. How could it be edible salt? It's okay to use edible salt, but the cost is very high. You can use it if you don't worry about dying!"

Fu Xin was still trying to recall the preparation process of nitrophosphate fertilizer, and he didn't notice that it was Fu Zhenbang who was asking him, because he sarcastically said to the other party that Fu Zhenbang would be very ashamed now.

"Okay, I got it, you've grown up too, I dare say you're old." Fu Zhenbang said unhappily.

After Fu Zhenbang said this, Fu Xin realized what he had just done. Immediately, Fu Xin became a little timid, and said embarrassedly: "Uh... I will continue what I said earlier, using ammonia water to vaporize or Industrial brine is used as a freezing medium to cool the acid solution to minus five degrees Celsius, at which point a large number of crystals will precipitate.

Then, separate the crystals by vacuum filtration, wash them with cold nitric acid, and send them to the calcium nitrate conversion section. Nitrophosphate fertilizer can be obtained by granulating to a certain extent! "Fu Xin was afraid that someone would interrupt him again, and what happened just now made him confide this long paragraph in one breath.

After finishing speaking, the scene suddenly became a little quiet, and Fu Xin said strangely: "Uh...don't look at me, think about it, do you have any questions?"

"Xiao Dong, have you remembered?" Jiang Haiyang asked the young man who was writing quickly while holding a pen.This young man is the recorder of this technical research, and he writes very quickly.

"Well, it's too fast, but I should remember it all, factory director, do you need to review it again?" There are several factory directors around here, although there is only one director, but the deputy can't offend No, Xiao Dong also asked the crowd.

Fu Zhenbang immediately replied: "Well, show this bastard!"

"Okay." After finishing speaking, Xiao Dong immediately put away the pen, handed the notebook to Fu Xin, and said, "Fu..." For a moment, he didn't know what to call Fu Xin.

"Just call me Xiao Fu, I'm younger than you, and I'm just here to help, I don't have a job." Fu Xin smiled kindly.I can't help but sigh in my heart at Xiaodong's writing speed.

"Oh, okay, Xiao Fu, check if there's anything wrong, and correct it for me, okay?" Xiao Dong didn't show any pretense, and directly called Fu Xin "Xiao Fu".

Fu Xin opened his notebook and saw a piece of beautiful cursive script on the paper. He couldn't help sighing: "Good calligraphy! I think Wang Youjun's calligraphy is similar to this!"

Wang Youjun is Wang Xizhi. Have you heard of "Lanting Collection Preface"? It was written by him, so I won't go into details.

"Hehe!" Xiao Dong didn't say much. His handwriting and his writing speed are indeed worthy of his pride. His handwriting is beautiful, and no one in the factory knows it. This has already made him very calm.

"Well, let me take a look first." The writing is very good, and Fu Xin's mood is also happy with the beauty of the writing, so after a short while, Fu Xin read all the recorded content, and then said: " Very good, there is no problem, now you should be able to test it!"

Hearing this, Jiang Haiyang immediately straightened his body and took a deep breath, and solemnly said to Fu Zhenbang at the side: "Old Fu, I don't understand these things, you, make the decision!"
