From Chief to Ball

Since it is for mining rather than military use, diatomaceous earth glycerin is available.If you want to detonate, you can only use mercury fulminate as the priming agent.

Making mercury fulminate must have been very difficult a year ago, even with sulfuric acid, nitric acid, alcohol, and mercury.

But now the difficulty has dropped, because of the advent of the simple thermometer.The readings are still touching, and the error can reach about three to five degrees within a range of one hundred degrees.

The ice-water mixture is used as a ruler, and the body temperature of the armpit is used as a ruler, and the boiling water is used as a ruler. The same amount of ice-water mixture and the same amount of boiling water are mixed in a cotton insulation porcelain pot to make a ruler. The scale is clearly marked.

In other words, today's thermometers have uneven reading scales, and the scales of each thermometer are also different, but the scale can be drawn in the opposite direction through the known temperature... It is equivalent to shooting a gun first and then drawing a target, but several important scales Just be sure about the number.

The magic of this kind of thermometer is that certain scales are roughly accurate, but the distance between the scales is long or short.

The azeotropic method is used to prepare volatile acid, nitric acid and mercury react at a certain temperature, and then add alcohol to control the temperature that can be measured by a certain thermometer, and a small amount of mercury fulminate can be produced.

After adding a passivating agent, it will make the thunderbolt less prone to explosion, roll it into a tube the size of a three-year-old child's penis, and insert it into the glycerin explosive as a priming agent.

The priming agent is only used for detonation. It is not necessary to make explosives. It is very dangerous. If it is commonly used, it is common to break fingers.

The lead azide primer can be produced in the laboratory at any cost, but it is too expensive. The power of a simple hand-operated generator is very small. The price of sodium produced by the stack method is higher than that of gold, let alone the local method of making nitrogen to form azide. Sodium's impossible procedure anymore.

This can be sorted out and given to the gentleman in the north to play. Chen Jian estimates that Mr. Mu is also working on the passivation of sodium nitrate and saltpeter and moisture protection. They are all in the explosives industry. I think the old man will like it.

As for the mines, quarries and other places here, it can only be said that Chen Jian's fate is not his. He can freely use the words "almost" and "make do with".

With mining picks, safety lights, mine carts, wooden rails, detonators, and explosives, Chen Jian felt that the image of Chinese miners would be full in the era of the Industrial Revolution.

If there is a disagreement, tie the explosive paper tubes all over the body, but don’t forget to insert the detonator, otherwise it will not be easy to blow up; or go to the river to fry fish in your spare time; there are often old miners missing a few fingers Wandering around in the mining area; hiding in the mountains and plains to avoid the gunmen hired by the mine owner to fight for rights by striking; calling brothers and sisters being used to fight with weapons in the neighboring mining area; hearing that there is gold sold and everything flocks to... Such an image will become more and more plump, Only tobacco is missing.

Seeing that the miners and the mine blasting master were coming, Chen Jian carefully took out the uncombined explosives from the saddlebag of the following horse and put them aside, startling the mine owner.

He knew the power of that kind of oil explosives. Although these rolls of explosives looked like a big firecracker, he knew that the power of this thing was much greater than that of firecrackers of the same size.

The mine master was invited and introduced, and Chen Jian called him a few times politely.The mining master also knew that these tracks and miner's lights were related to Chen Jian, so he was polite.

Looking at the several paper tubes on the ground, the mine blaster asked, "Is this the new explosive?"

Having seen a lot of strange things sent by Chen Jian, I didn't doubt the power of this explosive, just out of emotion.

Chen Jian found a chisel and hammer, and found a stone wall near the mining area, but he might not have found a support point correctly based on his feeling.

A hole was dug with a chisel, the safety explosive absorbed by diatomaceous earth was stuffed in, the detonator was inserted, and the fuse was tied.

Everyone retreated a long way, and the miners also wanted to see the excitement, so they all gathered around.

Chen Jian found a broken iron pot and put it on his head. He yelled for others to retreat further, and lit the slow-burning match tied to the fuse.

After waiting for a long time, there was a bang.

This time there was no thick blue smoke of black powder, only flying stones, gravel and dust.

The strong explosion effect combined with the right support point caused a perfect result. A large piece of stone on the stone wall was blown off, rumbling.

Several mine blasting masters ran over to check, thinking about the size of the explosives just now, they were amazed.

The mine owner didn't go to see it, and knew that he really needed this kind of explosive. If the price was not very expensive, it would be three to five times stronger than black powder.

More importantly, in this way, the position of the explosion is easier to control, and there will be no accidents that cause too much explosives to cause collapse.

Wang Zhe nodded secretly, thinking that this explosive is really a good thing, it would be great if it could be stuffed into the cannon.

But after thinking about it, Chen Jian would know that this thing is useful for the military, but he didn't mention it at all last time. Could it be that it is unrealistic to stuff this thing into a cannon?After all, Chen Jian is still a teacher of Xuegong, and Wang Zhe still thinks that Chen Jian must have his own reasons on this point.

After a few mining masters ran back, before Chen Jian could ask any questions, he praised them repeatedly.

"This thing is really useful. It's powerful enough."

"nice one!"

Chen Jian smiled, knowing in his heart that not only glycerin cannot be used in regular coal mine explosives, but also electric ignition is required to detonate.

"Masters, blasting mines is a big subject. Some skills, even the masters in the academy are not as good as you. This is the realm of the unity of hands and eyes for decades. Where to dig holes, where to plant guns, how can they not collapse... …These things cannot be learned in a day or two.”

"To be honest, a miner can be replaced, but a seasoned miner cannot be replaced at will."

After touting it, these mine blasting masters are also quite proud.How can I say that Chen Jian still has the identity of Mr. Xuegong, the same praise comes from different people, and the effect is quite different.

The mine owner also echoed a few words, and Chen Jian said: "These explosives still need to be improved, and it may take more than half a year. But this explosive is different from the previous gunpowder. How powerful is it? How much is the charge? How to detonate? These questions explode. Mining masters still need to learn carefully. How to fry? How to dig? These things are still the experience passed down from generation to generation by the masters."

"Well, since there is still half a year left, why not come to Nan'an with two of the most skillful masters, and let's figure out how to use this explosive together?"

Chen Jian understood that these masters would not easily teach some skills of mine blasting.Before the introduction of structural force and explosives into theoretical calculations, these masters have already summed up a set of skills that are not easy to spread, as the capital to settle down and be respected.

To a certain extent, this kind of hiding is not blamed on these veteran craftsmen. In businesses such as burning charcoal, ceramics, and dyeing cloth, it often happens that the owner invests in skills, and throws people away after stealing.

Tell the master in the front to get out, and over time, the craftsmen have developed the ability to live and work in the cruel class struggle.

The role of science is to make all seemingly mysterious techniques fully manifested with formulas and principles.Things like thermometers, measuring instruments, and the like can cost a lot of people their jobs, but also make the learning process easy and can be done in batches.

Today's mechanical foundation is not enough to support blasting and structural force analysis, so Chen Jian had no choice but to hire some old masters to justifiably "steal teachers".

The mine owner didn't expect Chen Jian's thoughts to be so dirty, so he didn't think much about it, and said, "In this case, then I will choose two masters with the best craftsmanship. But masters, let's talk about it. After we figure it out I still have to come back. After so many years of friendship, I won’t talk about anything else. Let’s do it this way, I will pay for food and clothing, but let’s be a villain first and then a gentleman. If we don’t come back after we finish our studies, we will have to pay some money. I can trust the two masters, but it’s still like this now, it’s better to take a different form.”

The two masters also understand that after working here for a lifetime, they still have feelings.I signed the contract without hesitation, but I made up my mind: only learn and talk less.

Chapter 1 Thirteen Oil Seedlings, Bamboo and Cattle

I went to a few more mines, invited a lot of mine masters, and agreed to go to Nan'an in half a month.

Chen Jian didn't talk to these mine owners about building roads and rivers.

Now that he has money in his hands, he doesn't want these mine owners to take a share of the profits. In the future, he will use canals and wooden rails as a means of checking and balancing these mine owners, and he will never allow them to intervene.

Whoever controls the roads and canals is the master.

By manipulating transportation costs, it is possible to help any mine to overtake other competitors, and to break through each other vertically and horizontally. Under the huge temptation, these mine owners will make the right choice as a way to disintegrate and reorganize the Nan'an Coal and Iron Guild important fulcrum.

As for inviting those mine masters to study and communicate, Chen Jian has no good intentions.

Now there is a Kaimeng school in Nan'an that has been completely inked.Part of the money was contributed by Chen Jian, and part of the party property and charity funds. There are 28 Mr. Kaimeng in the school, [-] members of the Mexican Party who followed the formal procedures or were transferred after Chen Jian bribed the school, and three were in the school. Inked edges.

The funded Kaimeng schools are all named after Hope Primary School. In addition to the normal literacy and arithmetic that Kaimeng needs to learn, two courses of physical education and interesting nature have been added, which are specially taught by people.

From the Kaimeng School, Chen Jian and comrades in the party reached a consensus: some education should start from the baby.

During the enlightenment stage, no political ideas were instilled, and even if they were instilled, they would not be able to understand.

However, the class monitors, various representatives, and committee members in the school must be elected by the children. They have been allowed to accept the concept of election since they were young, and they have subtly understood this concept since they were young.

The best publicity is not to open your mouth and talk endlessly to hear the thunder in a silent place, but to sneak into the night with the wind and moisten things silently and subtly. It is to let children accept what rights should be like when they are young, nothing more.
