When it was time to go to Shanhaiguan, Wei Bao went to Gunship Bay again, first to see how the well was doing? There is also the case of matches.

Matches, soap, and kerosene lamps are the new products that Wei Bao is preparing to use to open the market.

Deng Daliang was busy with a group of people from the water station, and when they saw Gongzi coming, everyone hurriedly stood up straight to greet each other.

"President, the water pipes have been connected, and this is about to begin." Deng Daliang said.

Wei Bao snorted, looking back and forth, this was the first time that electricity was used as power, and it was different from the water station next to Benjia that was powered by a steam engine.

This is the first attempt at electricity in this era!

"How many meters in total?" Wei Bao asked. Deep well water does not mean that the deeper the better, in fact, whether it can be used for a long time depends on luck.

"More than 80 meters." Deng Daliang replied.

Wei Bao nodded, secretly thinking that the efficiency of the work is very good, and in just two days, he can build a water pipe more than 80 meters long, which is not easy in this era!

Wei Bao has iron here, but compared to copper, iron is easier to get, as long as there is silver.

The copper used for the water station next to Benjia is because he also needs to quote it, so the cost is higher.

The water station in Gunkan Bay is mainly used for industrial purposes, and it is in a hurry to open, so it uses iron pipes.

"You guys are busy with yours, don't worry about me, I just saw it." Wei Bao Road.

"Yes, President!" Deng Daliang promised, "Then I'll start now?" Can this pump be used when it is turned on? ”

Wei Bao said: "Yes, as long as there is water underneath, don't let the pump run idle!" Keep in mind that if you run idling, the circuit will be burned immediately. ”

Deng Daliang wrote it down and began to start the circuit.

At this time, a group of people from the Military Industry Administration heard that the president was coming, and they all came out.

Deng Erxian said: "Brother, have you done it all?" Is this about to start pumping? ”

Deng Daliang nodded, signaled his sister not to speak, and then touched his forehead nervously, the weather is cool today, but he is still sweating.

Deng Daliang's nervousness mainly stems from ignorance, and the use of electricity is completely ignorant.

Although Wei Bao probably popularized the knowledge of electricity to him before.

But where can such 'avant-garde' knowledge be explained in a few words?

In ancient times, people made a series of observations about static electricity. From these observations, it cannot be said that electricity is completely incomprehensible.

The properties of ores like magnetite are very different; Magnetite is naturally magnetic.

In fact, in the 17th century, where Webo is now located, European scientists were already studying electricity.

In 1600, the Englishman Gilbert invented the electroscope, which provided the experimental basis for the later study of electricity. In 1660, the German Curic built a friction starting motor.

In the eighteenth century, the quantitative nature of electricity began to develop, and in 1767 Plistri and in 1785 Coulomb discovered the law that the force between static charges is inversely proportional to the square of the distance, laying down the basic law of electrostatics.

In 1800, the first battery was made by immersing copper and zinc sheets in salt water and connecting wires to the Italian voltat, which provided the first continuous power supply and is the ancestor of modern batteries.

In 1831, Faraday in England used the change in the effect of the magnetic field to demonstrate the generation of induced current.

In 1851, he proposed the concept of physical power lines. This is the first time that the concept of transfer from charge to electric field has been emphasized.

In 1865, Maxwell of Scotland proposed the mathematical formula of the electromagnetic field theory, which provided the concept of displacement current, the change of the magnetic field can produce an electric field, and the change of the electric field can produce a magnetic field. Maxwell predicted the propagation of electromagnetic radiation, and in 1887 Hertz in Germany demonstrated such electromagnetic waves. As a result, Maxwell combined electricity and magnetism into a theory, and at the same time proved that light is a type of electromagnetic wave.

The development of Maxwell's theory of electromagnetism also explained the microscopic phenomenon and pointed out the existence of splitting rather than continuous charges, which Lorentz postulated in 1895 as electrons, and that the action of electrons is determined by the electromagnetic field of Maxwell's electromagnetic equation.

In 1897, Thomson confirmed that the electrical properties of these electrons were negatively charged. In 1898, Wayne discovered the presence of positively charged particles while observing the deflection of anode rays.

From particles to quantum, human beings have always described the world of "electricity" in terms of particles and waves that exist in nature.

The emergence of the quantum theory has put the originally constructed particle world to the test again. Heisenberg's "uncertainty principle" states that the speed and position of a particle cannot be measured at the same time; Electrons are no longer countable particles; Nor does it run around a fixed track.

In 1923, de Broglie proposed that when tiny particles move, they have both particle and wave properties, called "wave-particle duality", and Schrödinger used mathematical methods to describe the behavior of electrons as functions, and used wave dynamics models to obtain the probability distribution of electrons in space.

In Bohr's hydrogen atom model, the radius of electron motion of an atom in the ground state is the position where the electron has the highest probability of occurrence in the wave dynamics model.

With the evolution of science, human beings have gradually understood that the values that can be obtained from the physical quantities of "electricity" are not continuous, and the laws they reflect are statistical.

Every progress of mankind, every progress, even takes half a century!

Therefore, Wei Bao himself doesn't know much about the three knives, even if he is a serious engineer, he can't popularize more knowledge of electricity to the ancients.

The generator starts first.

Deng Daliang pressed the button.

Then the button of the water pump was pressed.

More than 30 people from the Military Industry Administration, as well as President Wei's entourage, and some people from the Statistics Bureau in the Warship Bay, hundreds of people stared, waiting for a miracle to happen.

Although everyone still can't figure out how this kind of 'electricity' is generated, it doesn't prevent them from treating President Wei as a god.

What will happen?

This thought welled up in everyone's mind at the same time.

Wei Bao himself is not very nervous, full of anticipation at the same time, he can still remain calm, he has already checked the installation, every step is fine, and does not think that modern things can not be used in ancient times.

With the small noise of the water pump, the rotation of the machine, and the low roar, everyone present instinctively took a few steps back.

People still have a fear of the unknown.

"Out of the water!"

With a jet of water squirting out of the water pipe.

The first to call out was Deng Erxian! Girls are still more lively in the end. The men present let out a loud 'ah' exclamation at the same time. This kind of scene makes people's blood boil, and they can't believe their eyes.

They can still understand the steam engine, because in ancient times there were waterwheels that pumped water, probably the same principle, but the steam engine was made of big iron, and the waterwheel was made of wood.

But this kind of technology done with electricity is not something they can understand.

This water pressure is obviously much more powerful than that of a steam engine!

Wei Bao was also very happy, and said to Deng Daliang: "Congratulations! ”

"The president taught me how to do it, and everything was given to me by the president, and I didn't do anything, I just hit a batch of iron pipes." Deng Daliang said embarrassedly.

"Yes, congratulations to the president." Deng Erxian said in a loud voice.

Wei Bao smiled slightly: "It's all worth congratulating, it's good now, the water problem in Warship Bay will be solved in the future, there is no need to go outside to collect water, and it is more conducive to secrecy." "If you send people out to collect water every day, the water used by two or three hundred people, plus there are a lot of industrial experiments and industrial production, the amount of water used is quite large, and these two or three hundred people don't have to do anything, just carrying water, they may not be able to cope with it.

Everyone talked happily, saying that the water was no worse than the water station outside Benjia, and they were all very happy.

"In the future, this water station will be handed over to you, you must manage it well and strictly follow the regulations. Build cisterns to conserve water. Wei Bao said to Deng Daliang.

"Don't worry, president, I will do it!" Deng Daliang swore a promise.

Wei Bao nodded, and then asked Dong Huojin: "How is that batch of matches?" ”

The reason why Wei Bao didn't come to see it in the past two days is because he knows that the manufacturing process of matches is not complicated, and the existing technology has already matched all the raw materials, so it is impossible not to get it, but I don't know how the quality is? Can it be compared with the modern sample matches he brought.

"The president will know it when he looks at it, and I don't know what to say, so I can use it." Dong Huojin blushed. A man in his forties and fifties, twisting and pinching.

Wei Bao saw Dong Huojin's appearance, and his heart was a sigh, because today is going to Shanhaiguan, and the evening is the event of a new product launch, and at that time, Shanhaiguan and the entire Yongping Mansion will definitely be invited to watch the figures, if you can't hand over qualified products at this time, it will be a big trouble.

Wei Bao walked quickly into the shed of the Military Industry Bureau.

"Is that all?" Wei Bao picked up the 100 matchboxes stacked on the table, which he requested, to produce 100 boxes first, and then increase mass production after he approved it.

"Yes, President." Dong Huojin said: "President, let me demonstrate, right?" ”

"What? At risk? Wei Baoqi said.

"I don't know how to say it, I showed it to the president, and the president knew it." Dong Huojin insisted.

Wei Bao nodded.

Dong Huojin snorted and wiped a match.

The fire was so bright that it burst out and could release a head-sized fireball, but after only a while, it returned to normal, and the match burned out in three seconds.

Wei Bao sweated, now he knew what the problem Dong Huojin was talking about, no wonder he didn't dare to let himself come to wipe the match himself, it was really a bit dangerous.

"Why is the flame so big?" Wei Bao frowned, "Moreover, the burning time is too short!" It takes at least 10 breaths of time, and at such a time, people don't have time to light kerosene lamps! Even if it's time, it's fast. Wei Bao said.

"President, try a few more times, and it should be solved! I promise that within 10 days, I will be able to make matches like the samples brought by the president. Dong Huojin said: "Now the time is too rushed, I am afraid of delaying the president's big event, so I had to let people do this last night to make 100 boxes out." ”

Wei Bao sighed, knowing that he was in too much of a hurry, and did not blame the people from their Military Industry Department, "It's already very good, in such a short period of time, it can be done like this, it's good, it's okay to use it for display." It's just, there's no danger, right? Don't let people burn themselves when they light a fire! ”

"The president can rest assured of this." Dong Huojin said: "These 100 boxes are packed, we have tried at least 200, the largest flame, just like I just wiped, when you wipe the match, stay away from your eyes, so you don't have to worry." ”

"Okay, let's do it first." Wei Bao said: "Ship this batch of matches to the chemical plant, and it will be shipped in a unified manner." ”

After seeing that the well was successful and the matches were made, Wei Bao completed the purpose of this trip to Warship Bay, and felt very good, only soap and kerosene lamps were needed. These two things, he had seen before, and at that time they had barely reached the standard of being able to sell, and after a few days of improvement, Wei Bao believed that they would definitely be better than before.

Deng Erxian and several people from the Military Industry Administration accompanied him and followed the president out of Gunship Bay and went to the chemical plant.

"Soap and kerosene lamps, are they all right?" Wei Bao asked Deng Erxian.

Deng Er's rare blushing said: "It's better than before, but is it okay?" I don't dare to say it casually, but I still have to think that the president will be okay. Like matches, give us some more time, and I'm sure we'll be able to do better. ”

When Wei Bao heard this, he was a little relieved, and when he heard Deng Erxian say that it was better than before, this would already satisfy him.

After arriving at the chemical plant, Wei Bao was a little surprised.

The improvement of soap is not much, but the quality of glass has improved a lot! The large bubbles are almost invisible, and the surface of the glass is smoother, more shiny, and more transmitted, which can already meet the needs of the kerosene lampshade.

"Yes, how did you do that?" Wei Bao asked Deng Erxian.

Deng Er rarely saw that the president seemed quite satisfied, and said happily.

Because of the artificial excavation of the sand near the sea, these fine sand also slightly improved the manufacturing quality of the glass, which Wei Bao did not expect before.

Sand has a wide range of uses, in addition to being used as a speed-up agent for construction, road construction, filtration, breeding and landscaping, and smelting, it is also the main material for making glass, which contains silicon elements.

In sports, in addition to the sand pit, you can also make sandbags for boxing and flood control, which is indispensable! In daily life, it exerts the charm of cleanliness: factory workers wash their hands and feet with sand sand, wash wine bottles, porcelain, metal utensils, jade, silverware, etc.

Bright, smooth metal, wood sandpaper! In addition, volcanic ash or hot spring mud is a pet used by beauty children! It is also indispensable for making porcelain, and it is also used for salt-baked chickens in cooking, and if there is organic oil on the ground, the oil is spread with sand, and it is cleaned up as soon as it is sprinkled with sand, and it is used more often to clean up traffic accidents, and the sand bombs used for hunting, and the grenades used in the past, and the sandbags used for the battlefield and the raking field, and the sandbags are used for many purposes.

A large amount of sand is an industrial raw material.

"Yes, yes, I can think of ideas from raw materials. Well done. Wei Bao praised: "However, we can't be proud, we must make persistent efforts to solve the problem of finalization as soon as possible, we can only produce flat glass, and we will definitely not be able to meet the demand in the future." ”

"Yes, President." Deng Erxian replied.

It's a great treasure with everything you need.

Wei Bao was satisfied with the fact that after the glass was re-changed to a flat surface, the quality of the glass was stable, and the manufacturing process of the kerosene lamp was basically formed.

Although it is still impossible to make an oval shape for the time being, which will cause mass production of kerosene lamps and increase the cost, Wei Bao does not particularly care about it, and believes that in the near future, this technology will be able to overcome.

A few days a small fishing boat was converted into a sand mining vessel.

The sand mining ship is a floating mining and dressing combined device for mining underwater placer deposits or loose materials.

The ore is excavated by the excavation mechanism installed in the bow of the flat-bottomed ship, and is lifted to the silo on the ship, after the crushing, washing and grading of the circular and simple screen, the fine-grained material containing ore under the screen flows into the rough separation chute or jig rough separation, the tailings are discharged to the goaf behind the stern through the tailings chute or sand pump, and the waste rock on the circular simple screen is discharged to the tailings pile behind the stern through the belt conveyor or gravel chute.

Later, it was also used to mine sand platinum, cassiterite, diamond, rutile, monazite, zircon, sulfur, phosphate, coal, silver, fertitanium, silver-containing lead-zinc ore, iron sand, niobium, tantalum, thorium and other minerals and construction sand and pebbles.

All methods of mining useful minerals by sand mining ships are collectively referred to as sand mining ship mining, referred to as ship mining.

Generally speaking, for sand mining, the use of sand is different, and the form of excavation is also different. Sand suction ships are mostly used for fine sand, and chain bucket or hanging sand mining ships are mostly used for coarse sand.

Among them, the position of the chain bucket sand mining ship is relatively fixed, the moving range is small, and the moving speed is also slow, the sand suction sand mining ship is positioned and self-propelled sand suction when working, the former is more stable, the latter has a large range of activities, moves up and down quickly, and swings left and right.

The hanging and grabbing type is basically the same as the sand suction type, but the active sand mining is slightly slower than the sand suction type, and the range is slightly smaller.

The sand mining ship excavation method refers to the excavation sequence of the sand mining ship on the working face, also known as the mining method. The excavation method can be divided into two categories: layered mining method and trench mining method.

The layered mining method sand mining ship is mined layer by layer from top to bottom on the working face until the bottom plate; The ship moves forward one step and then layers from top to bottom. Its advantages are that the layered thickness of the excavation can be adjusted according to the properties of soil and rock, it is easy to control the full bucket coefficient, the uniform ore supply is conducive to stabilizing the beneficiation recovery rate, and the average lifting height of soil and rock is small, which is easy to operate and manage. According to the relative position of the axis of the ship and the centerline of the working face and the width of the primary excavation face, the layered mining method can be divided into three types: positive and oblique full face mining method and semi-working face mining method.

Positive face mining method. The axis of the ship coincides with the centerline of the working face, the angle of the ship's left and right rotation is basically equal, and the tail gravel pile is located in the middle. The advantages of this method are that the full bucket coefficient is high and the load of the ship's mobilization winch is uniform; The main disadvantage is that when mining a thick placer ore body, the tailings pile may be pressed on the side, which increases the dilution and loss of placer.

Inclined face mining method. This is in response to the shortcomings of the positive face mining method, when the axis of the ship deviates from the center line of the working face by a certain distance, the tailings pile can be deflected to one side, so as to avoid the other side of the ore pressing.

Half-face mining method. Roughly consider a working face as the left and right halves, first dig half of them in layers from top to bottom, up to the bottom plate, then immediately excavate the remaining half, then move the boat forward one step, and then take turns to mine back. This method is suitable for the condition that the soil and rock properties of the working face are quite different, or the soil and rock contain boulders.

The bucket chain or straw frame of the sand mining ship of the trench mining method is first lowered to the bottom of the ore layer or a certain height in the middle, and the groove is dug horizontally, and the soil and rock in the upper part of the groove fall down, and then the soil and rock of the caving are mined back and the bottom plate is cleaned. This method is suitable for mining old mining areas with tailings and gravel piles, high water dry gangs or surface frozen placers.

After the newly made steam engine passed the inspection and was deemed to be ready for production, Wei Bao ordered three more to be built!

Now Weibao needs to use steam engines everywhere in the local area to provide mechanical power, not to mention three, even if you build thirty more, it can also come in handy!

However, because Wei Bao was worried about the steam engine and did not dare to produce more, the simplest steam engine was still in the process of research and development and trial production, and it was far from reaching a stable standard.

After you have scheduled your local affairs.

After a simple lunch, Wei Bao took a group of entourages and a batch of new goods to Shanhaiguan.

Wei Bao's trip is different from the previous trip! He had two very difficult tasks.

The first is to make the sales of new products smooth and occupy the market, so that the industrial machinery of Weijiazhuang can be moved, in order to feed so many people, just by relying on agriculture, although it can also feed more than 10,000 people! But that's going to be very difficult, and, basically, there's not much development except for food and clothing!

It is impossible to rely on agricultural production to support the industrialization process, and even to support the entire Weijiazhuang, which is so vast and almost 1,000 square kilometers of land!

Because Wei Bao wants the process of industrialized cities.

Wei Bao's second task is the imperial examination that will start this month, and he wants to successfully pass the examinations of Tongsheng and Xiucai!

Xiao Sanyuan This kind of thing, Wei Bao doesn't dare to think about it, and he doesn't care very much, as long as he can get the fame of Xiucai.

When Wei Bao was talking to Zhao Jinfeng, he was so arrogant that he dared to say it even when he was admitted to the Jinshi.

But in fact, Wei Bao's goal has always been very low! If he is such a modern person, or a person with a very average language background, he can be admitted to the Ming Dynasty, he already feels that it is a miracle, and he can already be self-satisfied.

Wei Bao wanted to keep a low profile and did not arrange for someone to see him off.

Wei Dakang, Huang Ying, Fan Lao Pimple and his wife, Wang Zhihui and his wife, and a few other close people who knew the news saw him off.

Fan Xiaolin was unable to accompany her because she had a lot of management work in the local area.

Wang Qiuya and Xu Rui, as the managers of Wei Bao's presidential secretariat, can accompany them, the presidential secretariat was originally President Wei's auxiliary department, and they follow wherever the president goes.

This point made Fan Xiaolin feel very disappointed. She really wanted to be like Xu Rui and Wang Qiuya, and follow the president to Shanhaiguan.
