Dress to be a celebrity

This is what gasoline smells like...

how nice it smells.

It was as ecstasy as the smell he smelt every day in his previous life. It instantly reminded people of the past days when they could drive when they went out, but they couldn't walk when they got on the road.

He still followed the rules of fan smelling, took a few deep breaths of the wonderful smell full of familiar chemical pollution, and fanned Huan Ling a bit, and said proudly: "How is it, does it smell good? When I was a child It’s lovely to smell the gasoline behind the exhaust pipe, this is the smell of a high-horsepower motor, the smell of big industry...don’t smell too much, it’s poisonous.”

Huan Ling also habitually smells whatever he gives. When he heard the word "poisonous", he remembered that these petroleum products are poisonous. Long?"

However, he didn't read in the textbook that he would suffer from any illness after smelling gasoline. Song Shi was able to hand the bottle in front of his eyes, so it was naturally not very toxic.

He still taught Song Shi a few words, stared at him pouring gasoline into a glass bottle for storage, and then buried himself in the next step of kerosene fractionation.

The taste of kerosene is a little sweet, a little greasy, and not as addictive as gasoline.Song Shi didn't like the smell, so he poured it directly into a glass bottle, screwed on the frosted glass cap, stroked his chin and said, "Go back and ask the glass factory to make a kerosene lamp. This lamp is brighter than ordinary oil lamps. Let's hang some at home. The lighting at night is much stronger than ordinary candles."

It is easy to have soot, but it doesn't matter, just change the wallpaper frequently.

Anyway, I usually use oil lamps and candles for lighting at home, and they are smoky when lit, and the paper still needs to be replaced after a while, and using kerosene lamps will not cause much trouble.

There is still a lot of thick black liquid left in the flask, and if it is heated to more than [-] degrees, diesel oil can be extracted again.However, only kerosene was processed in the experimental process of the "fractionation of petroleum" in senior high school chemistry. They were also afraid that the temperature could not be controlled after heating, and the oil would suddenly boil. They checked that the thermometer had reached the top, so they simply ended the experiment at this step.

The remaining asphalt is stored first, and a more high-temperature-resistant bimetallic thermometer is made later for further processing.

This is a small step for high school chemistry, but it is a big step for the industrial development of Hanzhong Prefecture.

In the blink of an eye, Song Shi seemed to see a modern city rising from the ground in front of his eyes. When he closed his eyes and opened them again, there were still antique brick and wood houses with beams and columns in front of him. The houses were lit with red oil candles, and there were no gas lamps. use it.

Let’s set a small goal first—to make kerosene lamps available in Zhou Wang’s Mansion and their Hanzhong Mansion Yamen, and then try to extract Eucommia gum.

Even if it cannot be successfully made into soft rubber, it is good to be able to use it as plastic for insulation and waterproofing.

By the way, can this glue be used for shoe soles?

=============

After October, the new grain has been transported to Beijing, and the congratulatory gifts for the Shengshou Festival are also attached to the ship, and the major events of the year are settled.The government has collected enough grain and tax money, and can make up for the debts of the previous predecessors; the counties below, not to mention good harvests, at least have big households who can afford taxes, and their official achievements are quite decent, so there is no need to worry. Failed performance appraisal.

The people paid the grain tax, sold the surplus grain, and used it to make wine when they had enough grain; the newly harvested vegetables in autumn were either pickled cabbage, pickled pickles, or cut and dried vegetables; Eggs, you don’t need to save all your money to exchange needles and thread with the peddler, and you are willing to eat a few at home; the piglets caught in spring weighed a hundred catties, and if you raise them for another two months, you can just kill pigs for the New Year...

This year, the best days for the officials and people of Hanzhong government have arrived.

Students are excluded.

Except for Lueyang county magistrate and subordinate officials.

After the completion of the food distribution plan, the prefect of Song promoted the national literacy class in Nanzheng (demonstration) county.In every mile outside the city, in every township, in every street in the city, and in every workshop, children are invited to give lectures, and they are paid two liters of rice every month. Each person is given a set of "New Hanzhong Farming Enlightenment", a blackboard, white chalk, and colored chalk. One, enlighten the illiterate adults in the hometown.

According to the number of people in the village, the chiefs and townships of various places will each receive a sheet of new characters printed on papyrus and a multiplication table of ninety-nine. They will arrange a half-hour literacy course every day, and learn basic addition, subtraction, multiplication and division, and strive to reduce illiteracy as soon as possible. Rate.

Teaching books for half an hour every day can be exchanged for the rice grains that ordinary grannies deserve, which is quite a lot for some poor monks who have been trying for a long time and make a living by teaching.There are also some scholars who are not short of money and food, but just want a copy of "Agricultural Mongolian Book" edited by Song Sanyuan himself, and they would rather sacrifice their study and preparation time to take over the errand class.

The new students in these literacy classes can't enjoy the good days of high beds and warm pillows, and sleep until the sun rises; the Mongolian children and students who are not in the first class also have more things to do every day, and less time to write essays with friends and enjoy the autumn scenery.

Their lives are busy and tiring, and the students above them have no leisure.

Teacher Huan has now studied chemistry in the second year of high school. Apart from doing oil fractionation experiments by himself, he has also begun to lead students to do such experiments.

Straight-run gasoline is separated from petroleum, and gasoline is subjected to low-temperature fractionation above [-] degrees, and then deep-processed to produce petroleum ether...

From the postgraduate class to the professional class, the older and calm students took it all over, teaching these experiments and imparting a little chemistry knowledge at the same time.But unlike the textbooks, which start with difficult-to-verify knowledge such as elements and chemical bonds, the periodic table of elements is not mentioned for the time being. We only start with junior high school chemistry experiments and slowly show students the properties of different elements.

He single-handedly initiated the family's great cause of teaching. Song Shi got out and wrote to Lueyang County, instructing him to arrange to plant more Eucommia at the foot of the Qinling Mountains.

Eucommia ulmoides is originally a specialty of Hanzhong, but their Nanzheng County has been designated as an industrial and agricultural demonstration county by others. The land is given priority to build factories and open farmland, and there is no place to grow these medicinal materials.Moreover, Lueyang is the original place of Eucommia, and the Qinling Mountains are more suitable for large-scale planting of Eucommia.

In the past, because a large number of refugees came to Hanzhong to cut wood and reclaim wasteland, the forests in Lueyang became thinner, and a lot of medicinal materials such as Eucommia were harvested.Nowadays, many refugees are working in iron factories, lime factories, phosphate rock processing factories and other places built by Lueyang County. It is time to return the farmland to forests and build the Eucommia base in Lueyang County.

Although eucommia seedlings can also get glue, it takes a few years to get more glue.Next year's Arbor Day will plant eucommia seedlings in the middle of the mountain. In the future, they will develop a complete set of technology for fractionating oil in factories. No matter where a petrochemical plant is built, they will be able to extract gum immediately.

Although the extracted eucommia gum is not soft enough to make rubber soles, it has a texture similar to plastic and can replace resin materials to make small daily utensils such as toothbrushes, cups and plates, stationery, and waterproof boxes.

There is only one disadvantage, that is, it is not resistant to high temperature, and it will soften and deform when heated above [-] degrees, unlike plastic, which can hold hot water and hot food.Unless the properties become as good as ordinary rubber after vulcanization, he can't think of what to do with it for a while.

But if even he can't tell the benefits, how can Lueyang County firmly believe that there is a future in refining Eucommia gum, and is willing to plant Eucommia trees for him instead of opening mountains for farming.

He thought about it carefully for a while, and suddenly remembered that the heat-softening property of Eucommia gum is not a disadvantage—it is waterproof and can be deformed at will under high temperature, isn't it suitable for making water pipes?

Nowadays, field irrigation is still dominated by rough ditch irrigation. This eucommia glue can be made into water pipes, and watered by drip irrigation and sprinkler irrigation.If you want to change the direction and position of watering, you don’t need to connect valves and new water pipes. You only need to heat the old pipes and twist the angle slightly.

There is no need to consider the cost, as long as this irrigation concept is introduced first, and the petrochemical industry will start in the future, will there be no cheap plastic pipes available?

He immediately wrote to Lueyang County, and sent someone to ask the magistrate of Lueyang if he could return the farmland to forests, build a medicinal material base in the mountains, and plant a Eucommia forest next year.

In addition to Eucommia ulmoides, the water and soil in the Qinba mountain area are also suitable for planting many other medicinal materials. If some local specialties such as Codonopsis pilosula, Gastrodia elata, and sealwort can be interplanted, it can also increase the income of the officials and people of Lueyang County.

He is just now exploring the extraction technology of eucommia gum, and he didn't mention it in the letter before the water pipe was made. He only asked the magistrate of Lueyang County if he would change to plant medicinal materials.

The letter was sent to Lueyang, and there was a response soon.Lueyang County agreed to plant more Eucommia without any discount, and very nervously appended a sentence of his own guess at the end of the reply: "But my lord got a letter from relatives and friends, and heard that the imperial court wanted to add tribute to Eucommia and Tianma? "

Not yet, but in a few years, Eucommia gum will definitely become a tribute, and the amount of tribute will definitely increase.Let's plant the trees first to prepare for the supply of raw materials in the future.He shook his head slightly, took up his pen to reply, and comforted Lueyang County with a few words: "The imperial court has not yet added tribute to medicinal materials, but this official wants to use the dried leaves, seeds, and skins to make rubber for agricultural use, and is not picky about the appearance. .”
