It is a thermometer shaped like a dashboard, made of the principle of thermal expansion and contraction of metal. The bimetal sheet is used as a temperature sensing element to control the pointer, and the bimetal sheet is riveted together with a copper sheet and an iron sheet, with the copper sheet on the left and the iron sheet on the right.

Because the thermal expansion and contraction effect of copper is much more obvious than that of iron, when the temperature rises, the copper sheet pulls the iron sheet and bends to the right, and the pointer is deflected to the right under the drive of the bimetal sheet (pointing to high temperature); Conversely, when the temperature decreases, the pointer is deflected to the left (pointing to a low temperature) driven by the bimetal.

The production of the pointer thermometer was also very simple, and Ji Qiao asked the smelting technician to make some copper and iron sheets according to the requirements, and they were quickly made.

Then the water temperature test is carried out, and in the adjusted water temperature, the pointer points to make a mark, which does not require many scales and does not engrave numbers.

The advantage of this is that, in addition to being simple, it also prevents the technology from being leaked out.

After preparing all this, Ji Qiao began to let Mrs. Dongfang build factories and warehouses, and transform the silk production equipment herself.

1. Create a silk reeling car.

At that time, the method of silk reeling was to soak the silkworm cocoon in a hot pot soup, draw the silk by hand, and roll it around the silk basket. Pots and baskets are primitive silk reeling utensils.

Ji Qiao directly asked people to manufacture a seated pedal reeling car according to their own requirements, and the structure is composed of a stove, a pot, a money eye, a reeling star, a wire hook, a wheel, a crank connecting rod, a foot pedal and other parts.

Skipping the process of hand-cranked reeling the car, the person who reels the silk can sit and operate it together, using both hands and feet. One person can reel six to ten strands of silk at the same time, and the efficiency is increased by dozens of times.

Second, improve the loom.

At that time, the loom was a loom (called a waist machine) sitting on the ground, and this kind of foot-pedal waist machine was more laborious to operate.

Ji Qiao was directly transformed into a pedal lifting bias loom. This type of bias loom has a frame with a warp surface and a horizontal frame at an inclination of fifty or sixty degrees. The weaver can sit and work together.

......

Ji Qiao is mainly responsible for the design and commissioning of the silk reeling car and loom, and the carpenter does everything else.

Factories and warehouses are also under construction. The walls are all built with mud, that is, tools are made of wood, the soil is clamped with plywood, and then the soil is smashed layer by layer with wooden poles.

After the walls are built, the roof is made of trees and thatch.

Such a house is very comfortable to live in, warm in winter and cool in summer.

......

Lin Shi and Ji Ling were very bored during this time, and they followed Ji Qiao's ass every day, not knowing what to do.

often does some small damage, but is always yelled at by Ji Qiao.

Lin Shi was also very polite: "What's the use of you doing these ghost things all day long?" ”

"Do not make trouble, for you will know." Ji Qiao didn't bother to pay attention to them.

"It's too boring, come and play with us." Lin Shi was a little vexatious.

"In the future, there will be exciting things to do, you go and practice your martial arts well."

"My mother is also busy, who is she looking to practice?"

"Practice alone, or go into the city to find a princess to fight the landlord, don't bother me here!"

"Ji Ling, this dead child, if you don't block money, you can't play, and I can't afford to lose gambling money."

......

After more than ten days of repeated debugging and improvement, Ji Qiao finally developed a complete set of silk reeling cars and looms.

Then he began to let the carpenters mass manufacture.

At the same time, the test machine was carried out.

Two main types of silk were produced: ordinary silk and high-grade brocade, which were sold to commoners and nobles, respectively.

Ordinary silk production process: silk reeling - raw weaving - refining - dyeing.

High-grade brocade production process: silk reeling - refining - dyeing - weaving - printing - finishing.

Ordinary silk has low production cost and short process, which is the main way of silk weaving production and application at that time.

......

After seeing the trial results, everyone was amazed!

It is believed that this has increased the efficiency of silk production by at least ten times.

And due to the good water temperature and time control, the quality of the silk produced is much better than before.

Dongfang Jiao asked very seriously at this time: "Young Master Qiao, how do you know these things?" After you do this, the entire silk production process has been turned upside down, and there will be earth-shaking changes! ”

"Thinking with my head, I've been thinking about these things in my sleep for more than 20 days."

Ji Qiao knew that everyone couldn't understand it for a while, so he changed the topic:

"Mrs. Dongfang, from now on, the agricultural production will be in charge of Steward Chen alone, and the silk production will be in charge of you, you must send someone to take care of these things, and you can't let people smuggle them out. We must not only put down the silk business of Xuanwuhou, but also occupy the markets of various countries. ”

After hearing this, everyone looked at Ji Qiao in surprise! What the hell is this kid going to do?

Lin Yan asked curiously at this time, "Young Master Qiao, what is your real goal?" ”

Dongfang Jiao immediately replied angrily: "Why do you ask how much you do, just follow Qiao Gongzi!" ”

Lin Yan stopped squeaking.

Lin Shi has no interest in paying attention to these, she has been holding back for more than 20 days, and she is too boring. So he urged: "Ji Qiao, you have everything designed now, and you will accompany us to go shopping tomorrow." ”

"Okay, I'm going into town tomorrow for some business." Ji Qiao replied.

......

The next day, Ji Qiao took Lin Shi and Ji Ling into a silk village called "Hongyun", wanting to cooperate with the store owner.

The scale of this silk village is okay, Ji Qiao has already sent someone to inquire about the situation, and knows that the boss's name is Chen He.

Chen He also knew Ji Qiao and Lin Shi, so he said directly: "Young Master Qiao, Miss Lin Shi, let's go into the back room to talk in detail." ”

......

After everyone sat down, Chen He asked, "Young Master Qiao, how do you want to cooperate?" ”

Ji Qiao was very direct: "Explain in advance, the purpose of my cooperation with you is to take down a few other silk and satin villages, I don't know if you have the guts?" ”

"Young Master Qiao, we do business to make money, play with you, I can't afford to play!"

Chen He was just worried that he wouldn't be able to make money, and he didn't know that Ji Qiao was going to deal with Xuanwu Hou's Silk Village, otherwise he wouldn't dare to talk to him.

Ji Qiao asked, "How much money can you make in a year?" ”

Chen He replied truthfully: "My store is not good, less than 200,000 yuan." Xingwu Silk Village accounts for one-fifth of the entire Linzi market, and they can make at least five million a year. ”

"200,000 yuan is 20 taels of gold, I will give you 40 taels every year, and after the profit exceeds 40 taels, I will divide you into 30%, how about it?" Ji Qiao asked.

It's very tempting!

But Chen He was very puzzled: "Then you might as well open your own store, you don't need to partner with me!" ”

"We're too slow to do it ourselves, and I want it to be effective in a short period of time. Besides, I have to concentrate on producing silk and satin, and I don't have to work so hard to run the shop. ”

Ji Qiao knew that it would be troublesome for him to reopen the store, and he had to take care of every process.

The temptation is indeed great! Ji Qiao is also very careful!

After Chen He considered the meeting, he agreed.

Ji Qiao said again: "There is one thing that must be explained to you first, the owner of Xingwu Silk Village is Xuanwu Hou, and nearly one-third of the silk shops in Linzi City are Xuanwu Hou. ”

After Chen He heard this, he was very shocked! So he asked worriedly: "If I cooperate with you, will Xuanwu Hou be unfavorable to me?" ”

Ji Qiao encouraged: "Don't worry about this, Xuanwu Hou is going to deal with us." You can manage the store and we'll take care of the rest. ”

Although it was a bit risky, Chen He thought that this was also an opportunity, at least he could make twice as much money as before, so he made up his mind to cooperate with Ji Qiao.

Next, the two sides began to discuss the specifics, and then the contract was signed.
