Chapter 164: Li Mao returns

Zhang Zhimu, Chen Yufeng and the others had just returned to the top of the post, and Huang Yukun came over and called Chen Yufeng, "Uncle Chen, wait a minute, I have something to look for you." Then Huang Yukun, Chen Yufeng, and Zhang Zhimu came to Zhang Zhimu's office together. Song Jiaxin and Yang Qinglian came over to serve tea to everyone very sensibly, but Yang Yulin didn't seem to be busy with anything. Zhang Zhimu knew that she was a little embarrassed to see Huang Yukun here.

Huang Yukun saw the two beauties go out, and said, "Uncle Chen, I just want to ask you and Sister-in-law Xu when will you and Sister-in-law Xu do today?" Whether it is done before or after the Spring Festival. I'm all set. ”

Chen Yufeng, a battle-hardened person, was a little embarrassed when he encountered this, and said very shyly: "I haven't talked to Sister-in-law Xu about this, and I don't know what people mean." ”

Huang Yukun listened to Chen Yufeng's words, couldn't be happy, and said, "What else do you want to say." The things you brought to the children, Sister-in-law Xu accepted them without hesitation. Almost all of the clothes you wear are made by Sister-in-law Xu. When you weren't at home, Sister-in-law Xu cleaned up your house inside and out. I don't even know who you're marrying whom. I think if I don't talk about this, you're all too busy for anyone to take care of. However, Sister-in-law Xu has one request, she has to work after marriage. In fact, I can't do without Sister-in-law Xu here. ”

Chen Yufeng said: "Yes, this time is too busy. and Ouyang He made an officer's training textbook, Zhimu wanted to make an infantry drill code, and Ouyang He had no time to do anything about the formation. But these things are too important to train officers, and they must be used for a long time. ”

Huang Yukun said: "I don't understand what you are saying, but today I will listen to your true words, when will you do this." ”

Zhang Zhimu said: "I think so, Uncle Chen and Sister-in-law Xu have a good chat, and they have their own ideas." ”

Chen Yufeng is a big husband after all, and when things are said, he is still very happy, "I'll talk to Sister-in-law Xu about this myself, and see what she means." As for the matter of working after marriage, it is not a problem. It is impossible to let Sister-in-law Xu nest at home. Everything is safe in the rules of our kiln. ”

In the end, the result of Chen Yufeng and Sister-in-law Xu was that the marriage was done before the Spring Festival, and no one knew how the two of them discussed.

The kiln gang people were probably the busiest group of people in the Ming Dynasty, and Zhang Zhimu designed his own generator during the day and taught everyone at night. This time he talked about the principle of hydraulics. Before the start of the class, Zhang Zhimu saw that everyone had not yet arrived, so he said to Li Yunhe: "You have to take a good look at the safety of production." I heard that the chain of your hand hoist broke once, and it hurt someone. You have to pay attention to these things. ”

Li Yunhe said: "Alas, no one expected that one of the welded iron chain rings was not welded firmly and was welded. I haven't been hoisting anything too heavy, and I've been fine. This time, the base of the steam engine was too heavy, and as a result, there was a ring welding. Two people were injured, but fortunately, they were all traumatic. There was a broken leg and it was sent directly to Xiurong 'Shenshou Zhang'. Zhang Bingchen said that he should send it to the master to grasp some, otherwise he was afraid of leaving him disabled. ”

Zhang Zhimu said: "In the past two days, I have finished the course on hydraulics and air pressure, and you have to organize people to engage in hydraulic presses and air hammers. With the hydraulic press, our large blanks have to be forged and treated, and our barrels can be stamped with a single blow, so there is no need to work so hard now. Therefore, the blank of the transmission shaft of our marine steam engine must be forged several times repeatedly, so that the material can be improved. ”

Li Yunhe said: "I think the air hammer you mentioned is more useful. With it, there is no need to forge with a wheel hammer. ”

Zhang Zhimu said: "These two things are not very useful. Many things can be formed at one time by die forging, which not only saves costs but also improves efficiency. ”

When Zhang Zhimu was in class, he suddenly found Qingfengzi's master and apprentice in the crowd listening to the class, which made Zhang Zhimu very happy, because Zhang Zhimu was thinking about opening a chemistry course. However, Zhang Zhimu still kept his mind and began to talk about his hydraulic principle.

The basis of the hydraulic principle is the Pascal principle.

In a closed container, the pressure applied to the still liquid is transmitted to the points at the same time. This is Pascal's principle, or the principle of hydrostatic pressure transfer.

Zhang Zhimu used chalk on the blackboard to draw a picture and explained:

The pressure is equal to the applied pressure divided by the area under force. According to Pascal's law, applying a certain pressure to one piston in a pressure system must produce the same pressure increment on the other piston. If the area of the second piston is 10 times the area of the first piston, then the force acting on the second piston will increase by 10 times that of the first piston, while the pressure on both pistons will still be equal. In other words, the pressure can be increased by increasing the area of the second piston.

The hydraulic principle relies on the static pressure of the liquid medium to complete the accumulation, transmission and amplification of energy in a certain machinery, so as to realize the lightweight, scientific and maximization of mechanical functions.

There are four main categories of hydraulic components:

1. A hydraulic pump that converts mechanical energy into liquid (mainly oil) energy (mainly pressure energy).

2. Hydraulic control valve to regulate and control pressure energy

3. Hydraulic actuators (hydraulic motors, hydraulic cylinders, hydraulic swing motors) that convert pressure energy into mechanical energy

4. Hydraulic accessories necessary for the adjustment of pressure energy and liquid itself

Determined by the characteristics of hydraulic transmission, it has the following advantages

1. Various components of hydraulic transmission can be arranged conveniently and flexibly according to needs.

2. Light weight, small size, small motion inertia and fast response speed.

3. It is convenient to operate and control, and can realize a wide range of stepless speed regulation.

4. Overload protection can be realized automatically.

5. Generally, mineral oil is used as the working medium, and the relative moving surface can be lubricated by itself, and the service life is long.

6. It is easy to realize linear motion.

Zhang Zhimu himself has never engaged in hydraulic work, so he can only talk about some principled problems, and how to solve the specific work must be done by Li Yunhe. But these people in the kiln gang turned out to be some skilled craftsmen, and what they needed most was a direction like Zhang Zhimu. One of the biggest characteristics of the workers and technicians in the kiln gang is that they are willing to learn and do new things. You can see people arguing about technology in restaurants and baths all the time.

As soon as the course was over and after answering some people's questions, Zhang Zhimu came to Qingfengzi and asked, "I haven't seen you since I came back from Zhangjiakou, where have you been these days?" I'm about to start a chemistry class, and I'm afraid you won't hear it. ”

Seeing Zhang Zhimu coming over to talk to them, Qingfengzi's master and apprentice stood up, and Qingfengzi said, "We just arrived, and we heard that you are giving a lecture today, so we will put down our things and come over." Fortunately, I didn't miss the class. The rest is a long story. It's all over for a while, so let's talk slowly. Now I'm hungry all the time, and I don't have the strength to say anything. ”

Only then did Zhang Zhimu know that Qingfengzi's master and apprentice hadn't eaten, so he rushed to listen to the class hungry.

Zhang Zhimu said: "Let's go, I'll accompany you to dinner." Chat while eating. ”

After Zhang Zhimu and their caravan left the kiln, Qingfengzi and Zhang Shoutan hesitated. They felt that it was time to leave the kiln, but they didn't know why Qingfengzi, who had always been very detached, was also confused, he had traveled around for many years, and he had never been so reluctant to give up on a place. Could it be that your heart hasn't let go yet? Qing Fengzi's answer to himself was that the main reason for his reluctance was that there was Zhang Zhimu's knowledge here, and they hadn't fully learned it yet, and it was this knowledge that really attracted him, not because he was doing anything wrong. However, the master and apprentice felt that they were being served here every day like guests, and they were embarrassed to stay like this.

Zhang Shoutan said: "Master, it's better to do this, let's go back and make arrangements, come back with our own luggage, let Mr. Zhang help arrange a place, we will stay, I think Zhang is always a cheerful person, he will definitely agree to let us stay in Yaogang for a few more days." ”

Qingfengzi said, "Good idea. But guarding the altar, I think so, since you can't become a monk with me, it's better for you to stay in the kiln and follow Zhang Zhimu to do it. This is a place where you can show off, I think now in the Ming Dynasty, there is no place where people can live like the kiln gang people. ”

Zhang Shoutan has followed Qingfengzi for many years, and he is really inseparable from the master, he said: "I can't do without the master." If the master is in the kiln, I will be in the kiln. ”

Qingfengzi said: "It's not promising. If you don't leave home, it's very difficult for you to attain positive results. This is where your talents come in. And to be able to learn something, and to be able to make a difference, what kind of coincidence is this, you don't know how to cherish. To be honest, I'll go back to the mountain to make arrangements, and I'll stay a little longer when I come back, and you're ready to let Zhang Zhimu arrange something for you. I think Zhang Zhimu is definitely not an ordinary person, he will definitely have something unusual. Don't miss this opportunity. ”

As a result, when the two of them met at the meeting, the master and apprentice each brought a dozen people. Zhang Shoutan brought some relatives and friends from his family. It turned out that Zhang Shoutan went home and told his childhood friends about such a place as a kiln, these people couldn't stay one by one, and when they heard that Zhang Shoutan was going back to the kiln, many people had to come with him, Zhang Shoutan couldn't help it, thinking that these people had worked hard for a few years and had culture, and Zhang Zhimu would definitely welcome them when they arrived at the kiln. Qingfengzi returned to the mountain and gave a few days of lectures to the senior brothers and disciples on the mountain, which shocked the people on the mountain, but they didn't expect Qingfengzi to gain so much from this trip, and it was obvious that Qingfengzi was far from finishing what he had learned. After Qingfengzi introduced a place like Yaogang and a person like Zhang Zhimu. Everyone in the mountain sighed very much, they all thought that they were all masters on the mountain, but they didn't expect that there were really people outside the people. When Qingfengzi said that he was going to go down the mountain and stay in the kiln for a few more days in order to learn more things. And all the people on the mountain could not sit still. There was no way, this time Qingfengzi took one of his junior disciples and more than a dozen disciples down the mountain together.

This time, Qingfengzi and Zhang Shoutan came with a total of nearly 30 people, and Zhang Zhimu was of course happy. He has a leader in his future chemical business.

Zhang Zhimu made a request to them, they had to participate in the work when they arrived at the kiln, and of course they would stay free. In Yaogang, both monks and lay families are paid equally for equal work. Employees can have different beliefs, but they cannot force others to have the same beliefs, nor can they interfere with other people's beliefs. Qingfengzi said: "These are all right.

Of course, these people in Qingfengzi were quickly attracted by Yaogang, and soon they were under pressure, because they were a little dumbfounded when they saw the textbooks of Yaogang Primary School, and even the textbooks of primary school students, they had a lot of things they didn't understand. Almost everyone in the kiln is attending different classes, and there are people everywhere who are studying knowledge. They know they're in the right place.

What made Zhang Zhimu even happier was that Li Mao rushed back in the wind and snow. This time, Li Mao took more than 50 people and more than 100 horses, and because he arrived in Xuzhou, the Yellow River was frozen, so most of the journey was by land. Worried that it would be unsafe on the road, Li Mao brought back more than 50 people this time. In order to bring more goods, they each brought an extra horse.

Li Mao's return made the minds of Yaogang really happy. Because Li Mao has been regarded as a member of the leadership core at the development planning meeting just held in Yaogang, Li Mao has also been ceremoniously welcomed when he returns to Yaogang. Not to mention the dark day of a meal, the new development project in Yaogang made Li Mao and the people he brought back even more dizzying. The quality of life of the kiln people has far exceeded their imagination.

Li Mao rushed back in a hurry this time because he had very important news to come back and tell Zhang Zhimu. This news is not something that can be clearly explained by the flying pigeon, and it is also related to the future development strategy of Yaogang in the south.

When Li Mao, Zhang Zhimu, and Chen Yufeng were present, Li Mao introduced that Zhang Xianzhong, the eighth king, sent someone to contact him and said that he wanted to form an alliance with Zhang Zhimu's kiln, because the areas where the two activities were not connected to each other, there was no conflict of interest, and cooperation was beneficial. Li Mao felt that the matter was very important, so he came back in person.

Zhang Zhimu thinks that this is a big deal, but the current situation is that Yaogang can't turn his face with the imperial court, because his strength is still very weak and is still in the development period. Therefore, he cannot openly form an alliance with Zhang Xianzhong. But Zhang Zhimu didn't want to refuse Zhang Xianzhong, because he would definitely have to form an alliance with Zhang Xianzhong in the future, and the position occupied by Zhang Xianzhong was the position of a distant friend and a close attack. If you refuse now, it will be inconvenient to contact you later.

Zhang Zhimu said to Li Mao: "Let's invite Yan Boju, Mr. Ouyang, and Mr. Lu to discuss it together." Mr. Ouyang is also very knowledgeable about current affairs. Zhang Zhimu did this, that is, to tell Li Mao that these people are the core figures of the kiln gang and can participate in the discussion of major matters.

After Huang Yukun invited the three of them, they also participated in the discussion together. This is also the core figure of Yaogang, the first time to seriously discuss a major matter of Yaogang. This matter soon came to the opinion that has always been reached, according to Ouyang He, at this stage, he and Zhang Xianzhong "only talk about business and not about other places". You can communicate with each other, help each other, and stay in touch. But the relationship cannot be further developed.

Li Mao said: "Zhang Xianzhong's intelligence system is still very efficient. It didn't take long for him to get word on several of our big moves. This time, his envoy offered to *****. Also buy war horses. ”

Ouyang He said: "The muskets can't be sold now, if we sell them, the court will soon know." This time, though, we have too many horses to sell to them. ”

Yan Boju said: "The war horses we captured this time are all good, and we can sell them more war horses like last time." ”

Li Mao said: "When I came back this time, I looked at our horse fence, and I couldn't see the edge at a glance, it was too spectacular. When I went back, I let out the wind first, saying that I was going to bring some war horses over and hang them to eat their appetite. ”

Zhang Zhimu said: "Zhang Xianzhong's affairs will be done as promised." Let's talk about the ticket number and the transportation company next year. How much cash can Yangzhou have now? ”

Li Mao said: "In the past few kilns, a lot of steel, hardware, tools, etc., have been exchanged for a lot of silver, and we have bought a lot of grain and other items, and there are less than 100,000 taels of silver left. ”

Zhang Zhimu said: "If you want to apply for a ticket number, this little bit of money is far from enough. I'll have to bring in a little more silver next year. ”

Lu Chengxiang said: "You don't need to transport silver, just transport the goods in the past." I've been worried about one thing though. If one day we turn against the court, then our silver will not be safe. ”

Zhang Zhimu said: "Mr. Lu is right, I have always been worried about this problem. ”

Ouyang He said: "In a short period of time, we can't fall out with the imperial court, and the imperial court won't fall out with us." So that we have time and do well in the South. At the same time, it is necessary to set up a secret vault that only a few people know. If I lose a little bit of gold and silver on the counter, I don't think I need to worry too much. In fact, we are prepared in advance, and all the money on the counter will not be lost. ”

Zhang Zhimu said: "The secret vault is a way, we now have reinforced concrete, we can build the strongest vault, and then specially designed the big steel door of the code." If there is no password and key, others will not be able to open the vault even if they find it, unless it is blown up with a large number of **. ”

Chen Yufeng said: "It's best that we can grasp the little sore spot of the imperial court and make them dare not touch us." It's a bit tricky, though. ”

Zhang Zhimu said: "We can't do this, when the conditions are ripe in the future, we will also expand our military strength to the south, and we will not be able to confront the court in the south for a while, and we can also occupy a place like Shuibo Liangshan, although we have not done much, but we can protect ourselves enough." At the same time, I also want to build a branch like our Yangzhou branch, which can not only be used for business and office, but also have defense functions. In case of trouble, it is difficult to hold on to it for a while and wait for foreign help. ”

Ouyang He said: "Mr. Zhang is right, only if we have a certain amount of strength can we fall out with the court, and we will definitely not drink the court before a certain amount." So that we can buy a certain amount of time. ”

Li Mao said: "We in Yangzhou have bought a lot of land near the wharf. I am very interested in Mr. Zhang's suggestion to build a department store, it is better to build a department store with a circle building, which can be built not far from the canal, and open a total of four gates, one of which is the water gate, and the boat can row directly from the canal to the water gate. In this way, it is much more convenient to enter and exit the goods. The ticket number business is in this circle building. ”

Zhang Zhimu said: "This is the best. But when you go back, you have to find a place where you can hide your troops as a countermeasure in case something happens. ”

Chen Yufeng said: "Everyone prepares for the worst in these things. Maybe at that time, we will take Yangzhou City down directly, and we don't have to bother with it. ”

In the end, it was decided to continue to prepare for other things, leaving 500,000 taels of silver to Yangzhou next year, and 300,000 taels of ticket numbers to Xuzhou, and then to carry out the business first.

The things that Li Mao brought back this time made Zhang Zhimu even happier. Lu Wenchen had already bought the soft manganese ore that Zhang Zhimu wanted to use, but when he arrived in Yangzhou, Li Mao happened to receive a flying pigeon message from Zhang Zhimu that he wanted tin and tin ore. As soon as Li Mao and Lu Wenchen discussed, Mr. Zhang could use the method of flying pigeons to pass on the book, and if he sent a letter to ask for this thing, it must be urgent. Through inquiry, they bought more than 1,000 catties of tin, but they couldn't buy tin ore. In the end, it was decided that Lu Wenchen would go to Huguang to buy Lianxi ore. Li Mao took part of the pyrolite ore and Lianxi back to Yaogang, and most of the goods will be transported back next year when the Yellow River is civilized.

However, thousands of catties of soft manganese ore and 1,000 catties of tin, that is, antimony, were transported back, which made Zhang Zhimu determined to make the decision to start the primer.

Now that the things in my hand are almost finished, it just so happens that Qingfengzi and Zhang Shoutan are back, so let's get the basic chemical industry up.

The main substance of the primer fired by the musket is white **, that is, potassium chlorate. In addition, antimony sulfide, sulfur powder, and glass powder are also available.

The technical route for making potassium chlorate is to use potassium hydroxide to pass into ** to generate potassium chlorate.

Potassium chlorate is prepared by the reaction of plant ash and lime water.

**Made with sodium chloride (table salt) manganese dioxide (soft manganese ore) plus concentrated sulfuric acid.

Zhang Zhimu found Qingfengzi and Zhang Shoutan and took them to see the device for making green alum oil (sulfuric acid). This made Qing Fengzi very interested, and Qing Fengzi asked Zhang Zhimu: "Has Mr. Zhang also been instructed by the masters of the Waidan faction?" ”

Zhang Zhimu said: "No, you will know when you finish my course, this thing is actually very simple." You see, after the alum oil is refined, the remaining thing is called iron oxide, which can be used to make anti-rust paint, pigments, and polishing powder. ”

Qingfengzi's master and apprentice were also very interested in the device made by Zhang Zhimu, and they kept looking at it.

Zhang Zhimu said to them: "I asked you to come here today to let you see me make a new thing. ”

Huang Yukun asked someone to send a bucket of plant ash. Zhang Zhimu took the plant ash, put the plant ash into a large wooden basin, let the water pour in and start stirring, and when the water began to clear, filter out the impurities, and put the clarified water into a large jar. Then put lime powder in the jar and stir. After clarification, the precipitate is filtered out and the solution is placed in the jar.

Put salt and soft manganese ore in another jar, cover a lid with two mouths, and plug the other mouth with a glass tube with a rubber stopper, in order to turn conveniently, use a rubber tube to connect another glass tube, insert the outlet of this glass tube into the jar containing grass and wood ash water, and then insert a glass funnel with a rubber plug in another hole, pour concentrated sulfuric acid through the funnel, and quickly plug the funnel hole with a rubber stopper. After heating the jar, a stream of yellow-green gas pours through the glass tube into the ash water. Although Zhang Zhimu and others wore masks in advance, and the whole device was also placed in a ventilated place, the leakage was still uncomfortable. The whole process of grass and trees gray water has been constantly stirred.

When the solution is not dissolved, that is, when it is found that there is a glass nozzle coming out, the glass nozzle of the ** is quickly taken out and put into the mixed solution of lime and salt.
