This one looks a bit like an earth building. [Read the full text]" Wu De commented.
"Yes, it is indeed influenced by the earth building. If such a building is successfully piloted in Baitu, all our residential areas will adopt such a structure in the future." Wen Desi was extremely fascinated by his design.
"Mr. Wen, this design is good." Mei Wan's face clearly showed "otherwise", "But there is still a difference between earth buildings and houses like ours. The outer walls of earth buildings are made of three-piece rammed earth, and the structure is It is very strong and of good quality, which can be called concrete. This is a brick and wood structure building designed like this. If it is acceptable purely from the perspective of security control, it will be very difficult to defend against enemy attacks..."
"The materials can be improved in the future. Now let's see how the overall living effect is." Wen Desi has a special liking for his design. "The brick and wood structure is only temporary, and it will definitely become reinforced concrete in the future."
"Yes, but there is a problem with the design here: if there is a biogas digester in each unit, the living population of each unit will only be 150 to 200 people. If these people do not have large livestock, the biogas production rate will be very low."
"It doesn't matter, even if it's just a street light." Wen Desi knew very well that the role of a biogas digester of this size is very limited, but the biogas digester here is mainly used to ferment manure so that it can be safely used in farmland. Reduce the spread of parasites and infectious diseases.
"Let's just build two or three unit buildings." Mei Wan gave in.
"You build it first. As for moving in, I have other ideas." Wen Desi said to Wu De, "Let's go down and talk."
Wen Desi and Wu De were talking about the issue of employee hierarchy. The reason why he thought of this issue was by chance when he was designing residence B for Baitu Village.
Since the residents of Baitu Village are mainly various skilled workers, their treatment should be better than that of ordinary employees who simply provide physical labor. Otherwise, it will not be conducive to widening the income bracket and promoting the enthusiasm of workers. It makes no sense and is inappropriate for a shipbuilder and a strong laborer to carry earth to receive the same wages.
"Then there's food. The current rationing standards for certain types of work here are too low." Wen Desi pointed out. Heavy industry is about to start. Some heavy and toxic types of work. Without strengthening nutrition, it may be difficult to ensure the health of workers.
To increase rationing levels. It is necessary to establish the location, technical standards and levels of workers. Otherwise there is no question of scale.
"It's hard for me to say this. I have no experience in industrial enterprises. Anyway, I have no opinion here." Wu De expressed his attitude.
Wen Desi stared at him for a few seconds. Nodding: "The main thing is to seek the opinions of the labor department."
"I simply manage labor," Wu De said. "The executive committee is now going to set a grade and remuneration system for employees. I support it with both hands. Regarding the issue of remuneration, I have some ideas."
As he spoke, he talked about some of his views on the current issue of employee compensation. The main reason is that the treatment of employees' dependents is too low. Children may be undernourished.
"Cheng Dong proposed at the executive committee meeting that a currency system will be implemented after the new year. I want to take this opportunity to implement a monetized wage system. Simple exchange vouchers such as work-point vouchers are increasingly inappropriate for current needs. .”
"Yes, that makes sense." Wen Desi said as he walked, "Which currency system do you agree with us implementing?"
"Are you talking about paper currency or metal currency, silver standard, gold standard, etc.?"
"right."
"I don't understand this anymore." Wu De knew that Chairman Wen must have his own research on the monetary system. He didn't know much about it, so it was better to say less. "I have no personal opinion on this issue and obey the executive committee's decision." arrange."
After Wen Desi and Wu De broke up, they decided to go to a glass factory to see the current status of glass trial production. The infrastructure construction of this glass factory was completed years ago. Guo Yi has sent many telegrams from Guangzhou, urging Chuanchuan Industry to supply goods as soon as possible. Selling the inventory on the Fengcheng wheel is not the answer, and the bargaining chip they offered to Zhu Cailao and Liu Xiang is also glass. Not only is it a joke, but it also affects your reputation. In addition to the trade and industry sector, there will also be a huge demand for glass in the future. After all, this is the only material that they are confident of making and can withstand the corrosion of most chemicals. The chemical industry sector is also counting on using glass to make reactors, containers and various pipes. Starting on December 23, professionals from various professional groups in chemical industry, machinery and metallurgy were assigned, and the glass research team, led by Ji Si, began trial production.
The first requirement for making glass is a pot that can withstand high temperatures. The pot used by the research team was brought from the 21st century. Although Ji Sidui knew that high-temperature-resistant pots could be made using the chemicals in bitter brine, ancient Chinese smelters could also make them. He remembered that there was a building built in the late Ming Dynasty in Yangcheng County, Shanxi. The ancient castle of Dimibao is built from the nearby iron smelting town of Runcheng.
Abandoned pots are used as building materials. But making a pot is still a skill after all. If the technique is not mastered well, it can easily explode during use. Back then, Wu Yunduo encountered the problem of repeated explosions of homemade pots. It wasn't until I found the skills learned from a dedicated craftsman that I finally passed the test. It is obviously impossible for anyone to make pots in Zhongli, and Lingao is not a major smelting town, so the possibility of finding local craftsmen is slim.
So I specially brought a batch of pots of different sizes for emergency use.
The glass-making pot is closed. The reason why it is closed is to prevent the glass liquid from being contaminated by soot during the smelting process. As for the raw materials, they are quartz sand, quicklime and soda ash.
Quartz sand is a quite abundant mineral in Lingao, and it is easy to obtain a large amount of high-quality raw materials, which can be ready for use after simple selection and washing.
As for soda ash, the time travelers do not yet have the ability to produce soda ash, but they have two emergency methods. One is to use plant ash instead. This is a fairly old craft and European countries have been using this raw material for a long time. Seaweed ash is the best plant ash for refining glass. Obviously the most indispensable thing in Lingao is seafood.
The second method is to use the Malubran method to make alkali. They have Glauber's salt bought from Guangzhou. After heating and dehydrating it, they mix limestone and charcoal in proportion and put it into a pot and bake it at high temperature to refine it. The stuff is ground finely with a millstone, stirred and dissolved in water, and then the alkali brine is filtered out and steamed to get soda ash.
Ji Situi considered that the second method was too troublesome, so he decided to adopt the first method of seaweed ash. This method has been used in Europe for hundreds of years, and there will be no big problems if they use it.
So Li Di, a naval scientist and mechanical enthusiast, took people to the beach to collect large amounts of seaweed, dry it in the sun and burn it to ashes on the spot, and then transport it back in wooden barrels.
While Li Di was collecting plant ashes, Mei Wan sent all his best masons. Their task was to build a set of glass furnaces. This method is very old and has been in use since the 16th and 17th centuries. The advantage is that it is simple and easy to perform and does not require too high temperatures for smelting.
The first furnace is the material sintering furnace. This is a furnace with a vaulted roof, divided into a combustion chamber and a sintering chamber. The raw materials of the glass are sintered into glass frit in this furnace.
The second furnace is round and consists of three chambers. The lower chamber is used for fire burning, and there are 6 arched openings on the outer wall of the middle chamber for placing glass pots. After the pot is placed, these openings are blocked with soil, leaving only a small opening. There is a small square opening in the center of the top of the middle chamber. Heat can flow into the highest chamber through this opening. There is an opening behind the highest chamber, and behind it is a ceramic annealing tunnel. After the glass product is completed, it is placed here to gradually cool and anneal.
Of course, in this group of people from all walks of life, any design will receive countless suggestions for improvement. In terms of the structure of this glass furnace, a layer of diatomaceous earth insulation bricks is added between the inner bricks and the outer bricks. This greatly increases the thickness of the furnace wall, but the insulation effect can save a lot of fuel.
Considering that the temperature of refining glass is at least 12ooc, although they know from technical literature that this type of glass furnace does not require a preheating chamber, Ji Situi and others can guarantee that it will be available. From another angle, a ceramic pipe is added to the highest room in the center of the top of the circular furnace to guide the discharged hot air into the preheating chamber and supply the blower for hot blasting.
After completing this improved version of the glass furnace, the chemical engineering group and the mechanical group jointly began firing glass experiments. The first firing process lasted for o hours, and in the end the solid raw materials in the pot finally turned into a sticky glass slurry. Everyone immediately started to try blowing, and the things that came out were weird and looked like anything.
"How can I sell this thing?" Xiao Bailang sighed when he saw these glassware with different shapes, many bubbles and green color in front of him.
"Bubbles can be solved by stirring. As for the color, as long as carbon dioxide is added, it will be transparent." Li Di said confidently, "But everyone's blowing skills are really bad. Practice more."
"Dioxide~, can you change it?" Xiao Bailang said dissatisfied.
"That's all I knew about this." Li Di really didn't know where they were going to find this dioxide~.
"Well, actually there is no need for carbon dioxide~," Ji Situi said, "It acts as an oxidizing agent and does not necessarily require carbon dioxide~. Nitric acid is also an oxidizing agent. Add this to proceed."
The so-called nitric acid is also saltpeter, and they still have a lot of this stuff. After several more attempts, the glass experiment team finally made colorless glass on the day before New Year's Eve. This achievement made many people in the industrial sector cheer: the time-traveling artifact glass was born!
