The corresponding method is to process bamboo tendons. Bopu's chemical plant is already capable of producing wood tar and coal tar. [No pop-up novel website] These two products are quite old products in the chemical industry.
Using a simple fractionation device, many different chemical products can be fractionated. 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 being made into some tar incendiaries by chemical plants and smeared on telephone poles along the highway, this black and dirty coal tar is also It was used for anti-corrosion during shipbuilding. There is still a lot left in clay pots. In addition to coal tar, chemical plants also receive large amounts of wood tar produced when wood processing plants process charcoal. The temporary warehouse is full of piles.
Because the fractionation tower has not been installed yet, 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 is local people or traveling people, there are people who are thinking about these things. The indigenous people's ideas were better. They basically prepared them to be used as fuel or waterproofed the boat. The travelers had their own unique ideas. Some of the dangerous things created by half-hearted chemical engineers could make Ji Sixui break out in a cold sweat. Come.
Upon hearing Mei Wan's request for help, Ji Sidui expressed his great welcome - it is better to have someone to use than not to use Mei Wan. 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 durable. It absorbs water again 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. The chemical ability of the time traveler It is still relatively limited and can only use the simplest craftsmanship.
After the treatment is completed, the bamboo reinforcement itself still needs to be physically improved to be suitable as a raw material for bamboo reinforcement concrete. One disadvantage of bamboo is that the surface is too smooth. Not only is it difficult to fix the bamboo bars when tying 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. Another method is to wrap iron wire around bamboo bars.
Fortunately, although the steel reserves in the Ministry of Metallurgy are unable to supply steel bars, they can still supply 18-gauge wire. It is very convenient to process iron wire. Just add the wrought iron bar to the steel template and use a power machine 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 to lay telephone lines, and the Ministry of Light Industry wants to start sewing clothes. Needle.
The entire construction engineering company was devoted to the work of tying steel bars. .This job has a certain technical content. If Mei Wan hadn't come from a construction site, he would have been a bit unsure about it. What's more, these are not steel bars, but smooth bamboo bars. A few people, along with a few construction workers commonly used in construction companies, took pieces of bamboo and wrapped them around and around again. The only reference was a few blurry pictures printed out. Several time-travelers had never done this job 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 discounted. 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. We just need to go over and ask the 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 - Bairen City is experiencing a new wave of construction boom, and houses are being built everywhere. The availability of prefabricated concrete parts is extremely beneficial to construction companies. Great convenience. 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 floor slabs were put into the construction of "new countryside" and stadiums.
The entire project progressed quickly due to the machinery used. After all, it would take dozens of workers a whole day to move an excavator in one hour. As for the rammed earth work, Mei Wan also adopted the mode of rolling the road roller and manually ramming the earth simultaneously, and worked 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 exhausted body back to the shade shed of the project headquarters. The temperature outside is now less than 1o, but he only wears 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 employee 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 the 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 enjoyments of another time and space now out of reach. Sometimes he really regretted why he came here. Isn't this the same as in the past - no, it's worse than before. At least then, Hou drank as much Coke as he 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 hardworking," Bingfeng said to Zhuo Tianmin. The latter did not answer, with a sad face - he had not been home for three days. Although his son was entrusted to Wu De's woman to see him, he still felt uneasy.
Yan Quezhi said: "I don't understand, why is the Governor so anxious for this thing? Is it needed now?"
"Parade, man."
"parade?"
"Yes, let the natives who come to the meeting see it. Show your power." Bingfeng has been busy finishing the project of the Army Club recently, and knows that the Army has been practicing formation after the year.
"Working for people hurts money, and laboring for people hurts money." Yanquezhi disagreed. "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 thought 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 just 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 accuse Mr. Ma unjustly. 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? We can't sell it in the canteen."
"Mountain eats mountain," Bingfeng curled his lips, "This is military tobacco distributed to the Army. Didn't we help 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 doing ****——"
"The Army is a pauper, but the Navy is more powerful." Bingfeng exhaled a puff of smoke with 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," Yanquezhi 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," Yanquezhi 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, is it our turn?"
"Yes, Mr. Mei might get one's turn."! ~!
