The daily life of the science master's book-wearing group

Chapter 267 BB Hairpins and Pointer Thermometers
Returning to Baoen Temple from the Nursing Home, Song Qingyue immediately sat down and began to write the experiment report.

Even if it fails, it is necessary to write a failed experiment report, and summarize it, and propose the next direction of work.

She wrote these reports very neatly and in detail, which will be used as teaching materials for the future science academy.

After the development is successful, she will also write a standardized scientific paper as a template for everyone to learn from.

There are stereotypes in selecting scholars by writing, and the scientific community also has its own paper norms.

There are many capable people in China, and the East Asians who have grown up in the temperate monsoon climate for a long time are the most hardworking and have a high IQ.Since traveling to this era, the wisdom of the ancient people has opened her eyes even more.

It is more important to teach people this set of scientific exploration methods and the thinking mode of how to extract laws from chaotic facts than to instill ready-made knowledge into people of this era.

At the beginning of May, King Su brought Song Qingyue a barrel of oil.

The pure benzene was not separated, but a pot of engine oil that could be used to lubricate the barrel of the gun was produced.

In mid-May, Song Qingyue, who experienced the N+N failure of raw material preparation, got a steel pressure cooker that she had been thinking about for a long time.

It is said that the master of the steamship in the south came up with a new method to solve the airtightness of the steam engine: using oil-soaked sackcloth as a sealing ring, it can achieve a very good airtightness effect.

Song Qingyue once again lamented the wisdom of ancient craftsmen!

This pressure cooker is huge and made of thick steel.

However, after taking a closer look at the pressure cooker, he could only shake his head and smile bitterly. The pressure cooker itself can bear enough pressure, but the inflation valve cannot be closed.

However, in addition to catalysts and a high temperature of 500 degrees Celsius, the conditions for modern industrial ammonia synthesis require a pressure of nearly 20.00 atmospheres to complete a conversion rate of [-]%.

Song Qingyue scratched her head nervously, and decided to make a simple thermometer and pressure gauge first.

Using the principle that two different metals expand differently when the temperature changes, a pointer thermometer that can measure high temperatures below 600 degrees Celsius can be manufactured.

Its main element is a multi-layer metal sheet composed of two or more metal sheets laminated together, and the metal sheet is made into a spiral shape.When the temperature of the multi-layer metal sheet changes, the metal of each layer expands or contracts by different amounts, causing the spiral coil to wind up or unwind.Since one end of the spiral coil is fixed and the other end is connected with a pointer that can rotate freely, when the bimetal feels the temperature change, the pointer can indicate the temperature on a circular graduated scale.

It is easy to draw the scale, first find the angle of boiling water, you can know where one hundred degrees Celsius is, and then divide the dial into equal parts to get the scale of other temperatures.

As for the manometer, Song Qingyue can make various pointer manometers with different measurement ranges and sensitivities, as long as they make springs of different strengths.

These two instruments made the masters very happy. The process standardization that Song Qingyue repeatedly emphasized seems to have progressed because of these two simple instruments.

However, the thermometer was still disgusted by the steel-making master. He said that 600 degrees Celsius was not enough.

Song Qingyue shook her head and said that she was powerless for the time being, she had no material, no craftsmanship, and couldn't make it.

The master steelmaker left disappointed.

Song Qingyue followed him and told him some thoughts on blast furnace steelmaking.

In fact, she knew very little about the specific industrial process of ironmaking, but the core idea of ​​reducing the carbon content in iron was taught to the master steelmaker.

This master had listened to his own chemistry class before and knew the most basic oxidation-reduction reaction. In fact, all iron-making and steel-making are based on chemical reactions based on this idea.

But still the same sentence, from theory to practice is always separated by thousands of mountains and rivers.

If there is a chance in the future, she will definitely suggest that the imperial court should set up a special mineral exploration department to be responsible for the exploration and research of the extraction of various minerals.

Now I can only look at the stars in the middle of the night and imagine the future, dreaming sweet dreams.

She didn't know where that stinking ghost Li Zhao was and what she was doing, but she actually missed him a little bit.

Now when I am in a bad mood, I always feel deserted when I go back to the meditation room of the temple, and no one can say anything nice to make her happy.

Song Qingyue has been in a bad mood for not being able to find a new explosive that is effective and easy to store.

When she couldn't cheer up, she continued to write the physics and chemistry textbooks that might be used in the future. In the process of writing, she got a foam fire extinguisher.

Because this stuff is really too simple, that is, sodium bicarbonate solution plus some soapy water, plus aluminum sulfate, without aluminum sulfate, concentrated hydrochloric acid is also available, but concentrated hydrochloric acid is easy to volatilize and is not as stable as aluminum sulfate.

Now she can easily prepare these most basic chemical raw materials.Draw a picture, and then write a manufacturing process, and the cave can directly make it according to the process steps she wrote.

But, it doesn't make sense to manufacture this thing now. The manufacturing cost at this stage is very high, and it cannot be applied on a large scale.

But Song Qingyue thought that after His Royal Highness King Su became the emperor, at least this kind of foam fire extinguisher could be used in the palace.

Time flies quickly in the busy.

In mid-May, the Liang family sent someone to send Song Qingyue the dividends from the south this year, all of which were business cooperation with the An family, the He family, and the Cao family in the past.

As for why they weren't delivered directly to her like in previous years, Song Qingyue didn't bother to investigate.

The amount of dividends sent after ordering is much less than in previous years, mainly because of the sea trade, there is not a penny of dividends.

Song Qingyue wanted to sneer, and she didn't know how much those companies had earned from smuggling in private. The sea ban would only make their related households earn more, and they even went to the north to cry poorly with her, thinking she was stupid!

As for the industries in which His Highness King Su participated in the shares, no money was sent this year, and Song Qingyue didn't think about it.

As long as you don't think about it, you won't feel sad.

Fortunately, the money in hand now is much more abundant than at the end of last year, and it also makes her feel more secure, let's regard it as a happy event!

Another recent happy event is that her bathhouse has finally been built!

According to her request, a skylight was opened on the top, glass was installed, and white tiles were pasted around the walls, which looked clean and bright.

The glass obtained at the cost price from Dad's glass factory actually doesn't cost much more. Glass is just rare and expensive. Like soap, the actual cost is not high.

In addition, in order to filter and disinfect the river water brought in, she also built a small water treatment plant next to the bathhouse. With a water treatment plant, there must be a soap factory.

Song Qingyue thought, if this small system could be put into operation, perhaps the bathhouse and soap factory could earn the cost of the school.

When the old Li family learned that the bathhouse built by the concubine Shizi was built, they were so nervous that they sent someone to inquire about the price. Hearing that the price was indeed a penny higher than their own, they immediately felt relieved.

Song Qingyue's bathhouse is priced at three pennies per visit in summer, and the scrubbers in it are paid separately, while the dilapidated bathhouse at Li's family is two pennies per visit.

But those who have gone to Song Qingyue's bathhouse once, don't want to go to Lao Li's dilapidated bathhouse again.Especially the women nearby, don't they just spend an extra penny?The white and clean bathhouse makes people like it at first glance. There is a thin piece of soap inside for free. After taking a bath, there is a place for drinking tea outside. Each person is given a cup of free hot tea. Thinking about it this way, the extra penny will be earned back.

By June, the weather was getting hotter, and Song Qingyue's research and development of new explosives still hadn't made any progress, but her hair had grown a lot.

This length is embarrassing, it is not long enough to tie up, it is hot, and it keeps sliding down to cover the eyes.

As needs arise, new creations follow.

She asked the craftsman of Zhenbao Pavilion to help her make a few BB clips out of thin iron sheets to hold her hair, which are the kind of hair clips with push-button switches.

Shopkeeper Liu of Zhenbao Pavilion has been depressed for more than half a year because of the news of his master's death.

The so-called one emperor and one courtier, if the prince is gone, then the palace must need a new prince.

With such a big money bag as Zhenbao Pavilion, I don't know if it will fall into the hands of the Second Young Master in the end.If the owner is replaced by the Second Young Master, shopkeeper Liu does not want to work for the Second Young Master in his heart!

This Zhenbao Pavilion is the dowry shop of the late princess, and he belongs to the former princess.

The second concubine has an arrogant and willful personality, and she has a bad heart. She often comes to Zhenbao Pavilion to take advantage of it. In order to directly touch her feet, she even asked her to wash her feet!
Shopkeeper Liu hated Xiao Ning and the second young master from the bottom of his heart.

So for the past half a year, shopkeeper Liu has been playing cards, drinking, lying down, and putting things on the table.

Why would he hand over a thriving treasure house to the second son and second concubine?His Royal Highness Shizi had previously hinted that the first concubine, Daning, was killed by Xiao Ning, and asked them to guard against the second concubine and the second son.

Shopkeeper Liu thought that the lord would hand over the Zhenbao Pavilion to the second son, so he waited and waited, not waiting for the change notice from the palace, but waiting for the new order from the concubine.

Suddenly seeing this new type of hairpin with a simple structure but very practical, it feels like a chicken blood has been beaten, and the whole person is refreshed.

"This hairpin...is wonderful!"

The shopkeeper held Song Qingyue's paper model, looked left and right, looked up and down, and the more he looked, the more exquisite he felt.

Mo Xiang smiled and said, "The Imperial Concubine said that it must be made of wrought iron. Silver and gold are not very elastic."

The shopkeeper smiled all over his face, and said: "Yes, after finishing the small ones, ask the masters to gilt them with a layer of gold, and then inlay a few pearls and gems, so that they will be beautiful!"

Mo Xiang shook her head, leaned over and said in a low voice, "Don't do it too hard! The Crown Princess doesn't have much hair now!"

Shopkeeper Liu was taken aback for a moment, then immediately looked sad, and changed his words: "Then use silk yarn and cicada silk to make silk flowers and velvet flowers?"

Mo Xiang nodded: "Small, more colorful."

"Okay! You can get the goods in five days, and you will be satisfied with the concubine! Miss Mo Xiang, go slowly!"

Shopkeeper Liu happily sent Mo Xiang away.

Five days later, before Mo Xiang had time to go down the mountain to pick it up, shopkeeper Liu got up early and came up the mountain with a large box of BB clips himself.

Song Qingyue stayed up half the night last night to write textbooks on physical chemistry. She had just woken up when shopkeeper Liu came.

"Concubine Shizi, I'm here to greet you." Shopkeeper Liu said with a warm smile.

"Aren't you busy today? Why did you come in person? Sit down quickly. Mo Xiang, bring some good tea to the shopkeeper."

Shopkeeper Liu hurriedly expressed his thanks.

He took out a thin and delicate black lacquered mother-of-pearl box with a bamboo body, and there were five small drawers on it.The shopkeeper pulled out the four small drawers, arranged them one by one for Song Qingyue to see, and said with a smile, "I don't have much time, so I'll make twelve pairs for you first. Do you like any of them?"

"So many!" Song Qingyue looked at those BB folders decorated with various crafts, and was extremely surprised.The shopkeeper is also too efficient, he has made so many beautiful things in only five days.

Although they are all silk flowers and velvet flowers, there are peach blossoms, plum blossoms, camellias, roses, chrysanthemums, orchids, and all kinds of them. They are decorated with various beautiful patterns with thin gold threads, and are also adorned with small pearls or flowers. Gemstones, so delicate and elegant, it is hard to put it down.

"You really put your heart into it, thank you Shopkeeper Liu." Seeing these things, Song Qingyue suddenly felt like receiving a gift, surprised and moved.

Perhaps it's been a long time since no one gave her a gift, and suddenly she got such a box of hair clips, her eyes were a little moist.

Seeing Concubine Shizi's eyelashes filled with tears, shopkeeper Liu was a little flustered, and hurriedly said, "Concubine Shizi, what's wrong with you, but you don't like it? Just take it back and redo it!"

"No! I just want to cry because I like it so much. In the past, when the son was here, I could receive gifts every three days..." She suddenly felt a little sad.

In the past, Li Zhao sent people to bring hairpins and rings to her every once in a while, and sometimes she didn't even bother to look at them, but now she suddenly realized that she was somewhat ignorant of good and bad.

Everyone in the room felt sad with the concubine Shizi.

Shopkeeper Liu waited for the concubine to calm down, and then said: "Concubine Shi, I came up to the mountain to find you today, because I want to discuss with you about opening a new store."

"What do you mean?" Song Qingyue didn't understand.

Shopkeeper Liu said: "Our Zhenbao Pavilion was the dowry shop of the late princess, and even I was the dowry of the late princess. Now our aunt and grandma of the Hou Mansion are gone, and the prince is gone..."

"Don't talk nonsense, the prince is fine!"

"Hey, hey! Look at the little crow's mouth!" Believe it or not, shopkeeper Liu slapped himself twice, "I'm afraid that the second concubine and the second son will have the idea of ​​the Treasure Pavilion. No matter how valuable the shop is, it's not as good as the one in the warehouse." Those things are worth a lot of money. The little ones just thought, why not Shizifei, you open another shop in your own name, we will sell this new style of hair clips, and I will slowly transfer the rest of the treasures to the warehouse of the new shop, so as not to be caught People took it!"

Song Qingyue blinked, nodded and said: "It makes sense, you can't wait for the son to come back to see, everything is gone. Then go to the princess to ask for it, it will inevitably make your face ugly. Shopkeeper Liu, you are a loyal servant, wait for the son to come back Yes, I will definitely tell him."

"Hey, it should be, it should be." Shopkeeper Liu didn't know what expression to make now, he always felt that Shi Zifei was indeed mentally a little abnormal.

"Don't think I'm out of my mind!" Song Qingyue glared at him, "I tell you clearly, His Royal Highness is alive and well, just wait and see with peace of mind!"

"Yes, yes! Damn the little one! The little one will pick an inconspicuous shop and open it in the past few days. Here are the account books for last year and the first quarter of this year, please take a look."

Song Qingyue took over the account book and glanced at it. She didn't have much research on jade and gemstones. She focused on the sales of soap and sheep oil.

"Sheep oil sells well, but soap can't sell?"

Shopkeeper Liu nodded: "Isn't it? The ones in our store are too expensive, and the ones made inside are not as expensive as ours, so they can't be sold anymore?"

Song Qingyue snorted, and said casually: "You can add some gold leaf, pearl powder, ginseng and deer antler slices, wolfberry, and saffron to the soap. You can make it up by yourself for the effect, and then put some broken gems on the surface or it won't help. The perforated small pearl decorations will be sold at an additional price of ten taels."

A few words made shopkeeper Liu's eyes shine, and he said excitedly: "It's wonderful! It's so wonderful! I'll go back and get ready, little one! Guaranteed that we will open for a big sale."

"Thank you Mr. Liu, I am waiting for your good news."

"Hey, I can't be called Mr. Liu." Shopkeeper Liu said, but his heart was bubbling with beauty, he put the account book back into the bag, and walked away.

"Slow down when going down the mountain! Don't fall!" Song Qingyue looked at his back in a hurry, and she felt better. She glanced at Zeng Maozhi and said, "Send someone to follow, don't tell him to fall."
