Xipo. Research Institute!
The ringing of the phone on his desk brought Zhou Yang's thoughts back to reality. He took a deep breath and picked up the phone!
As soon as he picked up the phone, the voice of the operator in the telecommunications room came from the other side: "Director, I just received a call from a comrade named Zhou Yawen. He said he was your father..."
"Transfer it in!" Zhou Yang said directly.
"yes!"
Soon, the call was transferred.
"Xiao Yang?"
Hearing that the voice on the phone was indeed his father's, Zhou Yang immediately said, "Dad, it's me. Why did you suddenly remember to call me?"
"Xiao Yang, we succeeded, we succeeded..."
Even though he was separated by the phone line, Zhou Yang could still feel his father's excitement.
As expected, my father and the others should have made a breakthrough in potash fertilizer production technology.
Of course, the reason why my father and the others were able to achieve a breakthrough so quickly was directly related to the formulas Zhou Yang had written down before.
Zhou Yang knew that the varieties of potash fertilizer currently produced in China include potassium chloride, potassium sulfate, potassium carbonate, etc., especially potassium chloride.
To produce potassium chloride, potassium rock salt is used, but potassium rock salt is generally a mixture of potassium chloride and sodium chloride. If you want to convert potassium rock salt into potassium chloride, you need to mix potassium chloride and sodium chloride. To dissociate into monomers, there are three main methods: flotation, dissolution crystallization and heavy media beneficiation.
The most commonly used method in China is flotation, but this method requires the use of a large number of chemicals, usually including collectors, regulators and foaming agents.
During the Chinese New Year, after reading his father's research materials, Zhou Yang discovered that they were in trouble with flotation reagents.
Therefore, Zhou Yang directly wrote down the chemical formulas of the three potions and inserted them into his father's research materials.
And my father suddenly hurried back to the northwest. Apparently he discovered those formulas and was anxious to go back and do experiments.
This phone call today should be a good news for myself that the experiment was successful.
Zhou Yang smiled and said: "Speak slowly, why are you so excited!"
"Boy, can I not be excited? We have finally broken through a major bottleneck in potassium fertilizer production technology. This is not only crucial to the Qarhan Salt Lake, but also to the national agricultural production. This is great news!" Zhou Yawen said excitedly.
"Okay, okay, I should be excited, but you should take it easy!" Zhou Yang said.
"Well, thank you, you're interested!" Zhou Yawen said.
Zhou Yang knew what his father was talking about, so he immediately smiled and said, "Looking at what you said, I am your son, do I need to be so polite?"
"I am not thanking you as a father, but on behalf of the millions of farmers in the country. With this technology, we can increase the production of potassium fertilizer by more than five times and increase the production of tens of millions of kilograms of grain every year. , it is a great good thing for the country and the people!" Zhou Yawen's voice was a little excited when he spoke, but he was more proud.
For such an important technology, we neither relied on assistance from Big Brother nor purchased it from abroad. We achieved major breakthroughs through self-research and development.
More importantly, the key formula for the breakthrough was provided by his own son. How could he not be proud as a father?
"Dad, you just need to know this, but don't tell it!" Zhou Yang reminded.
"Why, am I planning to ask your superiors for credit?" Zhou Yawen said immediately.
"Dad, your son, I am already as busy as a top. I don't want to be visited by people from the Ministry of Chemical Industry again. That would easily tire me out!" Zhou Yang said.
When Zhou Yawen heard this, he fell silent for a moment.
The younger son's current life is indeed a bit too busy. In addition to the mysterious research institute, he also has to take care of a lot of things in the village. Comrade Lu Zhengjun and the medical school also need him.
If the people in the Ministry of Chemical Industry knew that the breakthrough in potassium fertilizer production technology was also related to his son, Zhou Yawen would definitely find a way to get him to work as a cow in the Ministry of Chemical Industry based on Zhou Yawen's understanding of those people.
After thinking about it again and again, he sighed and said, "Then you have to think about it carefully. Once this matter is reported to the Ministry of Chemical Industry, the least comment will be a first-class prize!"
"What's there to think about? If I don't show up, the prize will be yours. The money won't go to anyone else!"
"Haha, then you are asking me to pretend to accept your award. I can't do it..."
Before his father could finish speaking, Zhou Yang interrupted him directly and said, "Why do we, father and son, have such clear distinctions?"
"But those medicines were obviously researched by you. Isn't this equivalent to stealing your scientific research results? Even if they are biological father and son, that is somewhat unjustifiable!"
However, at this moment, Zhou Yang said again: "Dad, I have a way to separate sodium chloride and potassium chloride, and the purity of the obtained potassium chloride is above 99.9%. Do you want to know?"
"I think, tell me what method?" Zhou Yawen said impatiently.
"Then if I tell you, does this count as stealing my scientific research?" Zhou Yang asked rhetorically.
"This... we are father and son, dear, what do we have to say about each other!"
Hearing his father's words, Zhou Yang couldn't help laughing!
"You bastard, why are you laughing? Tell me, do you have any other way to separate sodium chloride and potassium chloride?"
"Dad, in addition to flotation, you can also use dissolution crystallization and heavy medium separation to separate sodium chloride and potassium chloride!" Zhou Yang said.
"Two ways?"
"Well, the dissolution crystallization method takes advantage of the different solubilities of sodium chloride and potassium chloride in hot water and cold water. The potassium chloride mother liquor is heated and mixed with potassium rock salt... After cooling, the potassium chloride crystals precipitate and are separated. , wash and dry to obtain the product... If you need to prepare high-quality potassium chloride for industrial use, you can refine it by recrystallization, and the purity of potassium chloride can reach 99.9%."
Then Zhou Yang continued: "The heavy medium separation method is a method that uses the difference in relative density between rock salt and halite in potassium halite mines and adds a medium with a density between rock salt and halite to separate them. , where the heavy medium suspension can be prepared with pyrite powder and saturated brine.”
"But this method is suitable for the separation of large particles and high-grade potassium rock salt ores. If the particle size is less than 1mm, this method cannot be used because internal adhesion will lead to non-selective agglomeration between particles!"
After listening to these two methods mentioned by Zhou Yang, Zhou Yawen was completely confused.
After nearly half a year of research, he knows how difficult the technology of potash fertilizer production is. It can be said that not only is domestic potash mineral resources lacking, but the production technology is also far behind foreign countries.
The dissolution crystallization method that my son just mentioned is a relatively common technology abroad. There are also domestic units studying this technology, but the effect does not seem to be very good.
As for the heavy medium separation method, he had only heard of it, but it was far less detailed than what his son said.
Although it is still unclear whether the method his son mentioned can really successfully separate sodium chloride and potassium chloride in potassium rock salt, judging from his knowledge base and understanding of his son, it should not be a big problem.
At that moment, Zhou Yawen immediately took out paper and pen, and discussed these two methods in detail with Zhou Yang across the phone line.
He recorded all the two methods Zhou Yang said in detail, and also marked the details that needed attention one by one.
At the same time, Zhou Yawen also specifically asked Zhou Yang about the production method of potassium sulfate, and got the Mannheim furnace method and the comprehensive utilization method of alunite from him.
Good guy, the father and son were on the phone for more than two hours, and it didn't end until Chen Beixuan urged Zhou Yang to eat for the third time!
