Chapter 351 The Young Coal Chemical Industry
Several civil affairs officials and craftsmen watched with some puzzlement as the chief executive squatted beside a waste outside the coke plant and carefully observed something. He even stuck out a finger to dip a little, and put it under his nose to smell it. With a strange joy on his face.

This coke plant located next to the Heishan coal mine, in addition to refining coke for the Heishan Iron and Steel Plant, also dry-distilled coal, extracted coal tar, and made cloth dyes, which were supplied to the printing and dyeing factory established in Weihai.

During this period, Daming had developed a relatively mature printing and dyeing technology.For cyan alone, according to the records of "Tiangong Kaiwu", there are various dyeing techniques such as sky blue, grape green, egg green, and beautiful blue, and the overall dyeing technology has been able to realize the traditional red, yellow, blue, green, and blue. In addition to the six colors of white and white, it can also print and dye complex colors such as agarwood, camel, and lotus root.However, the raw materials used for dyeing are mainly extracted from plants, and have been expanded to dozens of kinds, and the color fastness is good.

Qi Tian provided Song Yingxing and many craftsmen with the method of using coal tar to produce dyes in later generations. After more than half a year of research and experiments, coal tar can be stably extracted from coal dry distillation, and more than a dozen dyes have been successfully synthesized.Compared with extracting from plants, this method has more reliable dyeing performance and more stable raw materials.

In fact, coal tar has a wide range of uses, not only as a basic raw material for dyes, but also as a source of raw materials for insect repellants, plastics, quinolines, medicines, pesticides, dyes, and color developers.However, Qi Tian knew nothing about the specific production process and synthesis method, and could only regret that his professional background was only civil engineering, not a chemical expert.

This coke yard is very close to the horse-drawn track. The coke and coal tar produced daily are all transported to the Montenegro Iron and Steel Plant through the horse-drawn track, and then sent to the steel blast furnace or transported to the construction site by horse-drawn carriage according to needs. Industry City Dock Storage.

Originally, today, Qi Tian came to Heishan Coke Plant to conduct a pre-expansion inspection, but he was attracted by the pile of dark and sticky things outside the gate, so he left a few officials and craftsmen and went straight to inspect it carefully. .

"I wipe, isn't this asphalt?" Looking at the pile of black sticky objects, Qi Tian couldn't help but feel a burst of ecstasy.As a time traveler who was born in civil engineering, I feel very familiar and familiar with this kind of building material, and the role of this kind of material is extremely important to Hanzhou.

"Boss, do you think it's inappropriate for the coke yard to throw this thing here?" Zhu Ze'an, the fortification chief, walked to Qi Tian and asked softly.

"That's right, it's really inappropriate to throw this thing here casually!" Qi Tian said with a smile.

"The smell of this stuff is really bad, and the accumulation here hinders people from coming and going." Zhu Ze'an said: "Later, I will arrange for people to find another place to bury these wastes to cover them up."

"No!" Qi Tian shook his head and said, "This thing is very useful!"

"Where can this thing be used?" Zhu Ze'an asked curiously.

"Road construction, roof waterproofing, underground seepage protection, etc." Qi Tian said: "I really didn't expect that the coke plant could actually get out coal tar pitch. In the future, with this kind of thing, our Hanzhou development can be accelerated.”

In the process of coal tar processing, the residue after distillation to remove the liquid fraction is called coal tar pitch. Coal tar pitch is the main component of coal tar, accounting for about 50% to 60% of the total. It is generally believed that its main components are polycyclic, Condensed ring aromatic hydrocarbons and their derivatives, the composition of specific compounds is very complex, and the difference in raw coal and processing technology will also lead to differences in composition.

Generally, at room temperature, coal tar pitch is black brittle lump, shiny, smelly, flammable and poisonous when melted.Coal tar pitch has low temperature stability and good adhesion to mineral aggregates, that is to say, it is suitable for paving roads mixed with gravel and slag.Although its climate stability is poor (large changes in cold and heat), the annual difference in temperature in the northern part of Hanzhou is small, so there is no need to worry about its thermal expansion and cold contraction.

"Let me explain to the people below. In the future, the bitumen after carbonization of coal tar, oh, these residual wastes, don't throw them away at will. Prepare a lot of wooden barrels for them and store them all. I will let people know how to use them in the future. Make a list." Qi Tian ordered to the chief of the coke yard.

Thinking about future generations, the first road paved with asphalt seems to have appeared in England in the 19th century.Now it seems that the honorary title of the first asphalt road will fall to Hanzhou.

"Also, in the future, when the coke plant is refining coke, no matter what kind of substance is extracted, don't throw it away at will." Qi Tian said again: "You can send some of these extracts to the Tiangong Institute and the Tiangong Institute in Jianye City. The Industrial Research Institute of Montenegro City, let everyone try to study the characteristics of this extract, and record it in detail. It would be the best if we can research how to use it!"

Qi Tian felt that the craftsmen and scholars of Hanzhou should try to understand and study the elementary physics and chemistry of this period, so as to improve the technological level of Hanzhou.

Since coal and iron ore are currently the most utilized minerals in Hanzhou, can the chemical industry in Hanzhou be developed from coal chemical industry and iron and steel chemical industry?If this can be followed to produce a series of chemical industry chain industries, it will definitely have a great role in promoting the establishment and development of Hanzhou's industrial foundation.

The two industrial bases of Hanzhou, Heishan and Kaiyuan, seem to be two huge monsters, devouring countless laborers.Whether it is the natives of Hanzhou or the natives captured from Timor Island, it seems that they will never be able to meet the labor needs of these two places.Most of the more than 700 immigrants who arrived last month have enriched themselves in these two places and become industrial workers in Hanzhou.

"General manager, our coke plant has already made the coal supply of the Heishan Mine a bit difficult. If we expand the scale, I am worried about whether the raw materials there can meet our needs in time!" Su Xintang, the owner of the coke plant Said with some worry.

"You don't have to worry about this." Qi Tian said in relief: "According to the news from Xinxiangpu, Commander Qi broke down the city of Ambon a month ago and captured 800 people. In addition, Xinxiangpu has also accumulated At that time, most of the thousands of captured natives will be sent to the Black Mountain mine. In this way, the supply of ore raw materials and coal there will increase significantly.”

"In addition, with the official opening of the eastern immigration route, we will continue to receive immigrants from Ming Dynasty in the future, and our population will continue to grow rapidly after half a year of immigration interruption. The strength of our Hanzhou lies in Industry, the foundation of industry is iron and steel, and the source of iron and steel is ore and coke. Therefore, you coke field and Heishan mine have a heavy responsibility on your shoulders!"

"Don't worry, chief executive, we will definitely do our best to live up to the entrustment of the Hanzhou people's government and the expectations of the chief executive. We will continue to expand our iron and steel smelting in Hanzhou, and think of it as a scale!"

"Actually, when it comes to the scale and intensification of steel smelting, the conditions in the west of Hanzhou are much better than here!"

------------

"How do you know that there is a large amount of coal and iron in the west of Hanzhou?" Luo Yuru asked curiously: "I have heard people say that you have never been there.

"Not only do I know that there is a huge amount of coal and iron there, but I also know that there is a lot of gold there." Qi Tian said with a smile: "In fact, it's not just Hanzhou. There are many undiscovered treasures in this world. Know a thing or two."

"You have clairvoyant eyes and good ears!" Luo Yuru rolled her eyes at Qi Tian, ​​"Even if you really know all these things, don't talk about them. Needless to say, as the general manager of Hanzhou, you can easily tell where there is something wrong." Mines, where there are treasures, people will be suspicious, and you have other hidden detection methods. Even if others don't suspect this, if you want to appear to know everything, it may make people jealous."

"It's appropriate to hide clumsiness, I know that. Don't you want to show off in front of my wife today!" Qi Tian looked at the gentle and jade-like woman in front of him, and tried to put on a serious face, and his delicate face was also tense. Tight, can't help but love and pity.

"You... you're talking nonsense again." Luo Yuru blushed, and gave Qi Tian a reproachful look, "When did he... marry you?"

"It's almost November, and the war with the Dutch may continue." Qi Tian looked into Luo Yuru's eyes and said seriously.

"Huh?" Luo Yuru suddenly heard Qi Tian change the subject, and didn't react for a while.

"At first, I thought that by the end of this year, the Dutch would feel that it would be extremely uneconomical to continue the war with us in Hanzhou. But now that I think about it, I'm a little wishful thinking." Qi Tian smiled and continued: "At the beginning, we said that we would fight with others. Listen, after the war is over, I will marry you. Now it seems that it is difficult to achieve. You... don't panic."

"You..., who is panicking!" Luo Yuru was ashamed and angry, "You are really losing your shape!"

"Haha..." Seeing the little girl being teased like this, Qi Tian couldn't help but become happy and burst out laughing.

"..." Seeing Qi Tian making jokes with her like this, Luo Yuru was a little ashamed, pouted, and looked at him dissatisfied.

"That's right." Qi Tian stopped his smile and said, "I was in a panic and wanted to marry you in sooner. But the sky didn't follow my wish, and the Dutch made things difficult, which made you grow older."

"You..." After hearing this, Luo Yuru was taken aback for a moment, then blushed and threw the book in her hand to the sky with anger.However, he was not very worried.In such a high position and busy with affairs, but also know how to spare time to tease with the woman he loves, it seems to be a bit of fireworks.

"Annoyed?" After a while, Qi Tian asked cautiously, seeing that Luo Yuru was still thinking about something with his head down.

"No." Luo Yuru looked up, smiled, and said, "I was wondering how grandpa made my aunt and grandma happy."

"..." Qi Tian looked at Luo Yuru's delicate face in astonishment, full of playfulness.
