The corresponding method is to process bamboo tendons. Bopu's chemical factory is already capable of producing wood tar and coal tar. These two products are quite old products in the chemical industry.
Using a simple fractionation device, many different chemical products can be fractionated from it. These days, due to the need for steelmaking, the metallurgical department is coking in Bopu, accumulating a considerable amount of coal tar. In addition to these black and dirty coal tar
The chemical plant made some tar incendiary bombs and smeared the telephone poles along the highway. It was also used for anti-corrosion during shipbuilding. There is still a lot left in clay pots. In addition to coal tar, the chemical plant also received a large amount of wood for processing.
The wood tar produced when the factory processes charcoal is piled everywhere in the temporary warehouse.
Because the fractionation tower has not yet been installed, and the fractionated products require acid and alkali cleaning, Ji Situi cannot process them all at once. However, there are so many things piled in the shed, not to mention the smell, and they have to find someone to guard them.
- Whether it's locals or travelers, there are people who are thinking about these things. The indigenous people's ideas are better, basically they are preparing to use them as fuel or waterproofing the boat, while the travelers have their own whimsical ideas.
Yes, some dangerous things created by half-assed chemical engineers can make Ji Sixui break out in a cold sweat.
Hearing Mei Wan's request for help, Ji Sixui expressed his great welcome - it is better to have someone to use it than not to use it. Coal tar, the most basic anti-corrosion material, is more than enough to treat bamboo tendons.
Mei Wan first soaked the opened bamboo tendons in wood tar. This process was not only for applying tar, but Mei Wan also hoped that through this method, the dried bamboo tendons could absorb the creosote in the wood tar, making the material
It no longer absorbs water and has an excellent antiseptic and insect repellent effect.
After soaking for a few days, make sure that the bamboo tendons have been completely soaked, take them out, and then evenly apply coal tar on the surface. Of course, if it is modern time and space, this processing method will be much more complicated, and the chemical capabilities of the time traveler are still relatively high.
It’s limited, so we can only use the simplest craftsmanship.
After the treatment is completed, the bamboo bars themselves need to be physically improved before they can be used as raw materials for bamboo reinforced concrete. One disadvantage of bamboo is that the surface is too smooth. Not only is it difficult to fix the bamboo bars when bundling them, but the concrete is also easy to move and bubble when bonded.
The method used is to adapt the shape of the bamboo itself and make gaps in the bamboo material. The other method is to wrap iron wire around the bamboo ribs.
Fortunately, although the steel reserves in the Ministry of Metallurgy cannot supply steel bars, they can still supply 18-gauge iron wire. It is very convenient to process iron wire. Add wrought iron rods to the steel template and use power machinery to pull and stretch it multiple times.
The process is extremely simple, and the raw materials do not consume much. I heard that the construction company wanted to trial-produce bamboo-reinforced concrete prefabricated panels. The Ministry of Metallurgy immediately expressed its strong support and promised to supply as much iron wire as needed. Anyway, various departments have recently needed iron wire: Lingao Telecom wants
Telephone lines are laid, and the Ministry of Light Industry wants to start producing sewing needles.
The entire construction engineering company is devoted to the work of tying steel bars. This work has a certain technical content. If Mei Wan hadn't come from a construction site, it would be a bit difficult to do it. What's more, the tying is not steel bars, but smooth.
Bamboo tendons. A few people, along with a few construction workers commonly used in construction companies, took bamboo pieces and wrapped them again and again. The only reference was a few blurry pictures printed out. A few
None of the time travelers had ever done this before, and soon someone saw blood on their hands and was gloriously injured.
"God, this is harder than steel bars." Yanquezhi cried bitterly.
Bingfeng nodded: "This thing saves materials but not effort. And the strength is also compromised. If it is so good, why not promote it."
Mei Wan also had some regrets at this time, but it was inconvenient to express it: "Now we have to solve the problem of having and not having. We even mix the concrete ourselves. How about we go over and just call a commercial concrete company to bring a few tankers?"
The first prefabricated panel was tested after three days of curing, proving that it can be used as a lightweight floor slab. The results are quite encouraging.
"However, believe it or not, it's best not to use this thing as a load-bearing part." Bingfeng was still a little worried.
Although that is said, this substitute was put into production immediately - Bairencheng is setting off a new wave of construction climax, and houses are being built everywhere. The availability of prefabricated concrete parts is a huge benefit to construction companies.
Convenient. Mei Wan immediately conducted comprehensive training for the indigenous construction workers in the company, teaching them how to tie steel bars and make prefabricated panels. Soon, the first batch of cement floors were put into the construction of "new rural areas" and stadiums.
Due to the use of machinery, the entire project progressed very quickly. After all, it would take dozens of workers a day to move an excavator in one hour. As for the rammed earth work, Mei Wan also used road rollers and manual tamped earth.
The work was carried out in parallel and overnight. At night, more than a dozen gas lamps and countless torch cages were lit to illuminate the construction site. All personnel worked in two shifts, day and night, and the construction site was buzzing with machines and people.
"This project really has the atmosphere of a big war." Bingfeng had just finished presiding over a section of the project and dragged his tired body back to the shade shed of the project headquarters. The temperature outside is now less than 10C, but he is only wearing one piece
The T-shirt was covered in dust and dirt, and his eyes were red because he had only slept four or five hours a day for three or four days in a row.
"Drink some Wong Lo Kat." Yanquezhi brought over a large plastic bottle, which was filled with withered grass tea made by Nanhai's own recipe. Although the Chuanchuanzhong Canteen has been handed over to the General Office, it is actually still the original owner of the Agriculture Department.
The team is at work.
"I would rather drink it cold and boiled than drink this thing." Bingfeng shivered when he smelled the smell of that withered grass tea. This thing is no better than canned tea from another time and space. At least it has sugar added and flavored, although it tastes good.
It's weird, but still acceptable.
Bingfeng poured some saline solution specially prepared by the Ministry of Health into his stomach, wiped his sweat with a towel, and finally let out a sigh:
"I really want to drink Coke in my dreams." He lamented, the small enjoyment of another time and space has now become out of reach. Sometimes he really regrets why he came here. Isn't this the same as in the past -
No, it was even worse than before. At least then I could drink as much Coke as I wanted.
"After repairing one section, seal it with stones, and don't wait for the other sections." Mei Wan directed at the construction site every day, her eyes red and her voice hoarse.
"Mr. Mei is really desperate," Bingfeng said to Zhuo Tianmin. The latter didn't answer, but looked sad - he hadn't been home for three days. Although his son was entrusted to Wu De's woman to look after him, he still felt that he was unhappy.
rest assured.
Yan Quezhi said: "I don't understand why the Governor is so anxious for this thing? Is it needed now?"
"Parade, man."
"parade?"
"Yes, let the natives who came to the meeting see it. Show their power." Bingfeng has been busy finishing the project of the Army Club recently, and knows that the Army has been practicing formation after the new year.
"Working for people hurts money, and working for people hurts money." Yan Quezhi disagreed with this, "Isn't it more important to expand the capacity of the hydropower station? The cost of building such a grand viewing platform is enough to build two large dams on the Wenlan River."
"You don't know how much the executive committee has invested in this time." Bingfeng took out a cigarette from his pocket and said, "Here is one."
"Why, you still have cigarettes in your hand?" Yanquezhi took it from his hand and found that it was a hand-rolled cigarette. The rough paper made it obvious that it was a local product, and the tobacco leaves inside were golden.
"This is tobacco brought from Macau by a foreign trade company. I got some and rolled it myself."
"I think this thing was built to satisfy the leadership desire of the leaders of the executive committee, right? Ma Qianxu might have been holding back his energy and wanted to shout, 'Hello, comrades, comrades, thank you for your hard work.'"
"Don't blame Mr. Ma. If you want to shout, it won't be his turn. Mr. Wen is the chairman of the executive committee. The most Mr. Ma can shout is 'please review' - isn't he the chief of general staff?"
"I think they are working together on this matter."
The two of them puffed away at each other. To be honest, the taste of the tobacco was very different from that of cigarettes - it was sun-cured tobacco, not the flue-cured tobacco commonly used in modern cigarettes. Coupled with the rough cigarette paper, it was only better than nothing.
"The foreign trade company got a special supply. Where did you get it? They can't be sold in the canteen."
"You have to rely on the mountain to support the mountain," Bingfeng curled his lips, "This is the military tobacco allocated to the Army. Haven't we been helping the Army build a club recently? I was in command at the construction site, so a lot of it was given to me."
"You kid is engaged in corruption——"
"The Army is a pauper, but the Navy is powerful." Bingfeng exhaled a breath of smoke with some envy and coughed twice, "If I hadn't been seasick, I would have joined the Navy. What a wonderful life..."
"It's so hard for us to work on the construction site," Yan Quezhi looked at Mei Lin, who was sweating profusely, instructing the workers to lay stones, and Li Xiaolu, who was holding a level to measure the level, and others. "Even women are working on the construction site."
"Are you really good at caring for women? Why, is that interesting?"
"Where," Yan Quezhi quickly clarified, "She doesn't say a word except about work all day long, and she looks like a man owes her five million. I don't think it's interesting at all."
"That's right." Bingfeng said, "We have to train some people, at least constructors, technicians, etc., so that we don't have to go to the construction site all day long."
"Didn't you say that we will build a school after the conference? We are also applying to open a major in the school: the Department of Civil Engineering."
"I don't want any construction workers. It's okay to have a secretary first. Someone who can help me squeeze my shoulders and legs after work is considered a bonus."
"Haha, there are less than 40 girls who are about to graduate from the nursing school. It's our turn?"
