Of course, there is no way to solve it, and the former Soviet Union was very interested in this very low-cost industrial explosive, and finally developed ammonium nitrate explosives that are not afraid of water, and the specific method Hong Tao really does not know.

However, he knew a local method, which was to dissolve rosin or paraffin in diesel oil, and then stir ammonium nitrate and some wood powder with the solution. After this treatment, the water absorption of ammonium nitrate is greatly reduced, making it possible to store it in a short and medium time. However, compared to other types of explosives, it is still very afraid of moisture, and it is best to re-crush it after the plate is formed before continuing to be used.

Now what he has to do is to teach Gao Yu how to do this metathesis reaction and precipitate ammonium nitrate crystals at the optimal temperature. This temperature has been found, and it is not clear how many degrees Celsius it is, but it can only tell Gao Yu how many gigagrams of mercury it is.

The mercury column is the scale of a simple thermometer, but it is difficult to measure the standard Celsius or Fahrenheit, so it can only be expressed by the height of the mercury column, such as the precipitation temperature of ammonium nitrate, which is that the mercury column rises to about 12 bars and 3 minutes.

The next step is to test how much ammonium nitrate with different proportions can withstand before exploding, find the most suitable formula, and then produce it in small batches for the use of mines and road construction teams.

That's right, Hong Tao did not intend to use this new type of explosive completely in the military field, but the most beneficial for it to play was civilian. With its help, it will be easier for humans to open roads and fill bridges in the mountains and waters, and the speed of mining will be increased many times.

After mixing ammonium nitrate and calcium carbonate, it can still be used as a good fertilizer, and it is not like ammonium sulfate is acidic, it has become a neutral fertilizer, which not only no longer acidifies the land, but also has a neutralizing effect on the acidified soil. At the same time, due to the addition of calcium carbonate, it has trace elements such as calcium and magnesium, which is very conducive to plant absorption.

"Didn't this official say that he wanted to promote your officer, I'm afraid the military position is not very suitable, no matter how high it is, it can't be as high as Wang Da, going home is equivalent to seeing a subordinate and a superior, and he still has to be bullied. Why don't you turn it into a civil administration, how about being a factory director? This official plans to build a fertilizer plant, and you go and run it. ”

Since it is a good thing that is conducive to the people's livelihood, and he has wasted so much effort that he has even given up his old life, he must not put it on the shelf, it must be used, and it must be used as soon as possible.

It is better to give this task to anyone than to Gao Yu, who himself is from a chemical laboratory, and is good at making glassware, and has the necessary credibility.

“…… The student still wants to continue his studies with Mr. ...... "If you want to say that the original Gao Yu was an official embryo who was very good at pursuing power, then now Gao Yu has not only changed his name, but also his personality, and he has become a very inquisitive chemist."

"Silly guy, the fertilizer factory is a big laboratory, and it will be many times bigger than the laboratory in Mawei City in the future. Do you understand how to apply what you have learned? It's useless to just master a belly of knowledge, you have to transform them into products to be called ability. This plant will be protected by special forces, and all personnel will be deployed separately, how about it, are you interested in trying it? ”

It is normal for Gao Yu not to know what kind of organization the fertilizer factory is, and Hong Tao must make him understand that the importance of this factory is no less important than that of Weiqiao Town. What kind of persuasion is very simple, just briefly talk about the scale and treatment of the fertilizer plant.

At present, in the Huangzhou and Ganliang Road systems, only the Huangzhou Bank and the Weiqiao Town Workshop are equipped with special forces, which is the highest level of defense, and it also shows their importance.

"Students are willing to ......" With this guarantee, Gao Yu has no worries, in fact, being an official or not an official is really not very attractive to him.

Since he almost died once, his temperament has changed dramatically, and he agrees more with what Wang Er and Wang Shi said. At the same time, there is another daughter-in-law like Wang Da, who really lost confidence in being an official. How big of an official do you have to be to suppress your daughter-in-law? It seems like it's a long way off.

Now that the plant manager is there, the fertilizer plant can't start construction right away, because it has to choose a suitable location. First of all, it has to be close to the river to fetch water and dump wastewater. Secondly, it can not affect the lives of residents, whether it is exhaust gas or waste water has a strong toxicity. Finally, there is the issue of safety, not only to ensure that the fertilizer plant is not attacked and infiltrated, but also to prevent it from affecting the surrounding residents in the event of an accident.

This place is very difficult to find, Hong Tao lying on the map for a long time, Huangzhou is definitely not successful, its population density is greater than Ganliang Road, and close to the mainland, all aspects are not suitable.

Liangzhou is obviously not the same, it is full of farmland and pastures, only the lower reaches of the Shiyang River are more desolate. But it's close to the desert, so there's no way to guarantee its safety, so you can't build another fortress to protect it alone.

Looking to the west, Ganzhou seems to be good. The newly built city of Ganzhou is not a city at all, but a military fortress, and the security problem has been solved. There is a Heishui River in the west of Ganzhou City, and a reservoir has been built upstream, which is already considered to be the middle reaches of Ganzhou City.

If a fertilizer plant is built, it will only affect the middle and lower reaches of the city, and the land in the south, east and west of the city can still be cultivated, and only the northeast will be wasted, and the cost should be minimal.

In fact, Suzhou is also quite suitable, there are mines and workshops there, and it is very close to Wang Da, so the young couple does not need to live separately. However, Hong Tao does not plan to put all his eggs in one basket.

If Suzhou really becomes the front line one day, smelting, forging, mechanical workshops and mines are relatively solid, and they will be destroyed if they are destroyed, but once there is an accident in the fertilizer plant, it will be a big bomb, which is too unsafe.

In the end, Hong Tao chose the site of the fertilizer factory on the east bank of the Heishui River, about five miles northwest of Ganzhou City, where there should be a plateau, which is very suitable for building a factory.

Gao Yu didn't have much to say about the address, and after receiving the order, he took Wang Wu and dozens of prisoners of war and set off immediately under the escort of the special forces. The prospect described by Mr. is so exciting, thinking about the future I can be comparable to Mr. Existential, and I can wake up with a smile when I sleep.

"Now he is very happy, and his daughter-in-law is four hundred miles away, and if you ride a fast horse, the two of you can meet once every ten years."

Looking at the distant convoy of boxes, Jiang Erlang still said cool things. Lian'er's mouth is not too strict, and the matter of Gao Yu and Wang Da's wedding night has spread on a small scale, and it has become a big joke in Liangzhou City.

"Why are you becoming more and more like a woman, are you getting down to business?" Hong Tao doesn't think this kind of joke is funny, one is his adopted daughter and the other is his student, isn't laughing at them just laughing at himself!

"The last general saw the boy from the samurai family, and also took the sample back and forth. Wait a minute, I'll pick it up. Jiang Erlang heard the displeasure in the adult's tone, and immediately stopped mentioning this matter, and ran down the city tower in three steps and two steps.

He had just returned from Weiqiao Town, and his mission was to pick up a very important item, and he didn't know anything. Just in time for Gao Yu and Wang Wu to leave, I came up to chat with Lord Shuaisi, but I didn't expect to touch my head.

What kind of sample did he have to send him, the commander of the special forces, with a few team members, to follow the dart car of the Shunfeng Dart Bureau to make a round trip to Weiqiao Town at the fastest speed? It's a wooden box, more than two feet long and one foot square, not too heavy, that's all.

"Open it, I didn't expect the blacksmith of the samurai family to come out with a great talent in mechanics!" Hong Tao seemed to know what was inside, and he was very calm with his hands behind his back.

"This is a steel plate crossbow? No, why are there so many wheels? Jiang Erlang pried the box open, and it was stuffed with dry straw. Further inside, there were several things of different sizes and shapes, wrapped in oiled paper. After tearing open the oiled paper, he seemed to understand, but he didn't quite understand.

The box contained parts of two steel crossbows, which were different from the steel crossbows of the New Army, with very short arms and were not mounted at the end of the crossbow, but were pierced halfway through the crossbow. Not only does it look a little weird, but the two ends of the crossbow arm are even stranger, there is no horn hook hanging strings, but it has become two steel wheels that are not round or flat.

"Look, this official will give you a magic trick......" Hong Tao likes to see others scratching their ears and cheeks and wondering, and then he has the opportunity to guide others to the maze.

"This is the Huqin?" Seeing that Lord Shuai Si assembled a few parts and put on a few bowstrings, the more Jiang Erlang looked at it, the more he looked like a bow and crossbow, so he simply let his mind fly again and guessed a more reliable object.
