Yang Yuanzhao didn't know that Feng Yuxiang, who was thousands of miles away, would give him such a big gift, about 800, after 4 months of rigorous training, most of them were soldiers of the old foundation of the Beiyang Army, under the leadership of Wang Jinming, they went to Baotou via Mongolia, this group of people, if they take root, Baotou will at least have a new infantry battalion, including nearly 100 gunners, such a group of elites, even if they are placed in the Beiyang Army, can be called the backbone, based on them, It's perfectly fine to expand a target.

Yang Yuanzhao's mind is more on the side of the real building, Truss continues to deepen in the field of power and gradually deepen, many power grid equipment is also under research, Yang Yuanzhao has leisure to grasp, other fields.

This time, among the personnel, whether it is scientists or workers, the number of people in the chemical field is the largest, except for the personnel who stayed in Shanghai and were in charge of Smith's room, the rest came to Baotou.

Three acids and two alkalis, at present, only the completion of caustic soda, that is, the construction of sodium hydroxide plant, next, sodium carbonate, sulfuric acid, hydrochloric acid, and even nitric acid projects, will also be completed one by one, their completion, will not only greatly promote the science and technology of Baotou, on the basis of the original, has obtained a huge and incomparable improvement, the original is somewhat vague, and even the project that cannot be started, for example, hydrochloric acid and sulfuric acid, can also be started.

Hydrochloric acid project, sulfuric acid project, is more important, take over more personnel, hydrochloric acid is a more widely used acid in the industry, in addition to the synthesis of various chlorides, in the dye has a great role, is the dissolution of many dyes, but also the additive of many dyes.

Dyes, is the future Baotou will inevitably develop, and will be a great development of the project, Yang Yuanzhao's all-in-one machine, the next task is very heavy, almost impossible to produce dyes, a large cotton textile group, out of the cotton cloth, can only be used as the basis of sales, the real money, or the finished cloth, is the so-called muslin, muslin has different patterns, even if it is just a separate color, its value is much higher than ordinary white cloth.

Some of the engineers who came to Baotou, a large part of them are from various dye factories, just right, taking advantage of the opportunity to build a hydrochloric acid factory, the dye factory was established, at least, to ensure that a batch of bright colors, at least, no one in the whole of China can dye out of pigments, these are the focus of the development of hydrochloric acid.

Like hydrochloric acid, sulfuric acid is an important industrial raw material, and in many ways, especially in sulfides, there is a huge use, and Smith's students and researchers have been involved in some vulcanized rubber projects in Shanghai's Shiyàn room.

Yang Yuanzhao from later generations, more than anyone else, hopes that the vulcanized rubber project has made a breakthrough, the original rubber, he is also a rare material, but whether it is the use of Cheng dù and the breadth, there is a huge difference with vulcanized rubber, only the appearance of vulcanized rubber, with this does not stick, not easy to break and other effects, a certain Cheng dù above the overall effect is very good.

Now Baotou is unable to make vulcanized rubber, even if it is the real room in Shanghai, before all aspects of the equipment have arrived, it can only do some basic production, but here, the real room is imminent

Of course, the more important role of sulfuric acid is still on the metal, as some incoming solvents and dehydrating agents, the greater role of sulfuric acid should actually be in metal smelting, some with physical and ordinary chemical methods, metal impurities that cannot be removed, can be removed and screened with sulfuric acid.

The progress shows that the two major acids have begun to be studied, and the results of these two or three days are good, at least the construction of two chemical plants has been basically smoothed out, and the various equipment transported from Taiyuan has also been carefully inventoried, and the plan for the construction of sulfuric acid plant and hydrochloric acid plant has also been put in place, just waiting for the arrival of workers.

Basically, the hydrochloric acid plant and the sulfuric acid plant use all foreign workers, which are relatively technical positions, in addition to the necessary key positions, a group of ordinary workers will be arranged on the remaining positions, and they will learn some operating procedures nearby, and finally, prepare for the expansion of production.

The construction of three acids and two alkalis, on the one hand, is to complete the tasks in the task system of the all-in-one machine, and on the other hand, it is not to lay a good foundation for Baotou.

About a week later, divided into several batches of workers, basically in place, large-scale three acids and two alkali factories began to set up and produce, steel structure, is still an irreplaceable workshop, building materials, larger and larger industrial areas, the number of steel structures is also getting bigger and bigger, when the cultivation task is completed, Yang Yuanzhao almost put the machine, all the production objects, replaced with a variety of steel pipes, for the construction of future steel structures.

Baotou's human resources, because a large amount of land entrusted to the Baotou company, became abundant, hundreds of thousands of people poured into Baotou, so that Baotou became narrow, all kinds of temporary housing, built, the previous residence, has also been reasonably used, for example, was made by Yang Yuanzhao, as a double bed in the dormitory, began to shine, for most of the workers who came to work in Baotou

Having a place to live that can shelter from the wind and rain is satisfying and comfortable, and the workers are relatively far away.

Qian Hu's engineering team has become a behemoth, with tens of thousands of workers scattered almost everywhere in Baotou, and a small number of them are still invited from other cities.

Such a huge number of workers, more than half a year of high-intensity construction, in the steel structure, has summed up a set of perfect, cutting effect is very good method, the construction of the steel structure, not only safe, but also save a lot of time.

Whether it is a sulfuric acid plant or a hydrochloric acid plant, the key lies in the reaction tank, most of the equipment can be placed in the open air, and only a small part of the equipment needs to hit the steel structure.

Everyone worked together, the construction of hydrochloric acid, sulfuric acid and sodium carbonate was rolled out, in Yang Yuanzhao's task system, the progress of the three projects was clearly displayed, at present, the total completion of the three acids and two alkali tasks was 67, which has exceeded about half, and the completion of hydrochloric acid and sodium carbonate has exceeded 80, and it is estimated that there will be a period of time to complete the construction of this project.

Among the three acids and two alkalis, only nitric acid is one, and there is no movement, as always, there is only less than 2 degrees of completion, that is to say, Baotou has so many more engineers and introduced so many projects, and nitric acid has not made any progress.

In fact, the production of nitric acid, Yang Yuanzhao has long had a plan, nitric acid, as an important basic raw material, especially in the production of munitions, occupies a very important position, not to mention the new explosive TNT, it is necessary to use nitric acid, that is, it is said that it is the ground fire of artillery shells or bullets, and it will definitely not be used if it is less and less counted.

The arrival of many engineers and researchers in the United States has made the other two acids and sodium carbonate complete the design and production, but the nitric acid has not moved at all, and it is impossible to just rely on the all-in-one machine to synthesize nitric acid.

Nitric acid must be on, is the relationship between the all-in-one machine, but also related to the safety of the entire Baotou, heavy industry base, there is no strong and powerful protection, this base is an empty word, what kind of protection, there is more strict protection of the army, and the strength of the army is based on all kinds of weapons.

Now, with the drawings copied by Yang Yuanzhao, the world's most advanced rifles, machine guns, light machine guns, and even artillery, except for large-caliber fleet artillery of more than 220 mm, which cannot be manufactured, most of the other artillery can be completed, perhaps, there are designs, and some problems, for example, naval guns are converted to continental artillery, heavy gun body and cannon body caliber, It's a huge problem, and the question of having and not having has been solved.

Now the key is not in the weapon itself, in and ammunition, in China, has been poor and backward, since 1840, Britain opened the door to China, China has been completely left behind by the world, for more than 100 years, there is no ability to produce bullets and shells, of course, small batch production and reloading, has been doing, but the scale is not large, from the warlord melee, to Chiang Kai-shek's reunification, and then to the War of Resistance against Japan, China imported a large number of guns and ammunition from abroad, squeezing a lot of foreign exchange, As a result, the economy and industry are underdeveloped, and this premise is that nitric acid cannot be mass-produced.

In later generations, there are many famous chemists, and even the magic of Hou's alkali method, but nitric acid has always been stuck in the neck, Baotou is still a small place, Yang Yuanzhao directly produces guns and ammunition, okay, he can even complete the production of guns of a division at one time, but it is impossible to support 10 divisions to fight together, but in the future, when the territory is getting bigger and bigger, there are more and more personnel, and the number of troops is increasing, the output of the all-in-one machine is probably a drop in the bucket.

Personnel from the United States, there are not many people who study nitric acid, at most they are just dabbling, Yang Yuanzhao does not plan to use traditional methods to make nitric acid, saltpeter can not be imported, in this era, the important role of oil, has not yet been demonstrated, the world, for raw materials control zhì is the strictest, but also the most important, undoubtedly so that saltpeter, any saltpeter origin, will be valued by the great powers, including Britain, the distribution of saltpeter, a certain degree of dù above, restricting every country.

During the First World War, Britain's strictest control over Germany was saltpeter, and it was precisely because of the storage of saltpeter that Britain could roughly estimate the scale of Germany's military industry and the amount of equipment, but Britain did not expect that Haber, a genius chemist, created a zào nature, using air and water to produce ammonia, and then, the chemical reflection of nitric acid, became the raw material of TNT, even if it was only 3,000 tons, it was enough for Britain to have a huge error in Germany's armament.

The raw materials for synthetic ammonia are air and water, this thing can be seen everywhere, and there are raw materials everywhere, in this case, any control of nitric acid is just an empty word, any strong country, no matter how strong, it is impossible to control the air and whom, only, the production of weapons is more about strength and production capacity, and is no longer subject to minerals.

Yang Yuanzhao thought that this is the case, China lacks saltpeter, there are not a few saltpeter mines, from the past, to the beginning of the 20th century, China's gunpowder, most of it, is made by the soil method, scraping nitrate from the toilet, or the prototype of the field, these are not Yang Yuanzhao's choice, among the scholars he found, there are a few chemical talents, initially exposed to the chemical reaction of nitric acid.

Ricks, a chemical engineer who once worked in the largest munitions factory in the United States, can be said to be an all-rounder, he is familiar with various munitions formulas, and this time, among the talents introduced by Harpy, in addition to Truss, he is one of the most valued people.

Yesterday I finished the project and waited for the review of the planning room, and Ricks was notified that he received the task of the heart and went to a new real room.

In the real room, Ricks saw two or three peers, all of whom came out of the military factory, and along the way, they also knew more or less about the common language, which often made them familiar with it quickly.

After a few simple inquiries, I knew each other, I didn't know, what was going on here, including Ricks, it was very strange, Baotou was a strange place, on the outside, it was a poor and backward place, not much different from other places in China, but this huge building, coupled with the countless equipment on the building, proved that the German and American company, here, is very influential and ambitious.

Sulfuric acid, hydrochloric acid, sodium hydroxide, sodium carbonate, all of them are industrial, more critical, very important heavy chemical raw materials, an idea, it seems that in an instant, flashed in Rix's heart, they are all from military factories, isn't it, this time to find them, for military production?

The more Ricks thought about it, the more he felt that the possibility was very high, looking at the other engineers, and the only technician who was called, almost all of them had worked in the military factory, in fact, there was no need to ask anything, and the results were already ready to be called.

Without waiting for him to ask others, Yang Yuanzhao pushed the door in, these people he selected were currently in Baotou who had been exposed to nitric acid, among them, there was also a shipyard in the navy, for high-pressure closed containers, there was a certain experience, in his opinion, these people, plus his guidance, should be able to get synthetic ammonia out.
