"This one looks a bit like an earth building," Wu De commented.
"Yes, it is indeed influenced by the earth building. If this kind of building is successfully piloted in Baitu, all our residential areas will adopt this 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 are still differences 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 and can be called concrete. This is a building with a brick and wood structure - it is designed like this. If it is acceptable purely from the perspective of security control, it will be difficult to defend against enemy attacks..."
"The materials can be improved in the future, but 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 is used to light street lights." Wen Desi knew very well that a biogas digester of this size has limited functions, 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 try building two or three unit buildings." Mei Wan gave in.
"You do it first. As for arranging the move-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 future employee hierarchy. The reason why he thought of this issue was by chance when he was designing residence B in 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. A shipbuilder and a challenger
It is obviously unreasonable and inappropriate for strong local laborers to receive the same wages.
"Then there is food. The current rationing standards for certain types of work in the future are too low." Wen Desi pointed out that heavy industry is about to start, and for some heavy and toxic types of work, it may be difficult to ensure the health of workers without strengthening nutrition.
To increase the level of rationing, the types of work, technical standards and grades of workers must be established, otherwise there will be no scale issue.
"It's hard for me to comment on this issue. I have never worked in an industrial enterprise and have no experience. Anyway, I have no objection here." Wu De expressed his attitude.
Wen Desi stared at him for a few seconds and nodded: "The main purpose is to seek the opinions of the labor department-"
"I just simply manage labor." Wu De said, "The executive committee now wants to set a grade and remuneration system for employees, and I support it with both hands. I have some ideas about remuneration issues."
As he was talking, he talked about some of his views on the current employee remuneration issues, mainly that employees' dependents were paid too low and children may be undernourished.
"Cheng Dong proposed at the executive committee meeting that a currency system will be implemented after the year. I would like to take this opportunity to implement a monetized wage system. Simple exchange vouchers such as work-point vouchers are increasingly inappropriate for current needs.
.”
"Well, what you said makes sense." Wen Desi said as he walked, "Which currency system do you agree with us to implement?"
"Are you talking about paper money or metal currency, silver standard, gold standard, etc.?"
"right."
"I don't understand this." 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.
Arrangements of the Committee.”
After Wen Desi and Wu De broke up, they decided to go to the glass factory to see the current status of glass trial production. This glass factory completed the infrastructure project two years ago. Guo Yi had sent many telegrams from Guangzhou, urging the crossing industry to
Supply as soon as possible - always selling the inventory on the Fengcheng wheel is not the answer, and the bargaining chip they offered to Zhu Cailao and Liu Xiang is glass. Not being able to make it for a long time is not only a joke, but also affects the reputation. In addition to trade
, the chemical industry sector will also have great 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 also hopes to use glass to make reactors, containers and various pipes.
. Starting from December 23, professionals were drawn from various professional groups in chemical industry, machinery and metallurgy, and the glass research team, led by Ji Si's resignation, began trial production.
The first requirement for making glass is a high-temperature resistant crucible. The crucible used by the research team was brought from the 21st century - although Ji Sidei knew that magnesium chloride in bitter brine could be used to create a high-temperature resistant crucible,
Ancient Chinese smelting craftsmen can also make it. He remembers that there is an ancient castle in Yangcheng County, Shanxi Province, Tumibao, built in the late Ming Dynasty. Its walls were built with discarded waste crucibles from Runcheng Town, a nearby iron smelting town.
However, making crucibles is a specialized technology after all. If the technology is not mastered well, it will easily explode during use. Back then, Wu Yunduo encountered the problem of repeated explosions of homemade crucibles. Until he finally found the method learned by a specialized craftsman.
Skills are required to pass the test. It is obviously impossible for anyone to make crucibles in Zhongli, and Lingao is not a major smelting town, so the possibility of finding local craftsmen is slim. Therefore, I specially brought a batch of crucibles of different sizes for emergency use.
.
The crucible for making glass is closed. The reason why it is closed is to prevent the glass liquid from being contaminated by soot during the smelting process. The raw materials 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 make soda ash, but they have two emergency methods. One is to use plant ash instead. This is a very old process, 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 crucible to bake it at high temperature to refine it.
The material that comes out is ground finely with a millstone, stirred and dissolved in water, and then the alkali brine is filtered out and evaporated to obtain 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 would be no big problem for them to use it.
So Li Di, a chemical and mechanical enthusiast of the Navy, took people to the beach to collect large amounts of seaweed, dried it in the sun, burned it to ashes on the spot, and then transported it back in wooden barrels.
While Li Di was collecting plant ashes, Mei Wan sent his best masons. Their task was to build a set of glass furnaces. This method is very old and has been in use in the 16th and 17th centuries. The advantage is that it is simple and easy.
OK, smelting does not require too high a temperature.
The first furnace is the material sintering furnace, which is a furnace with a vaulted roof and is 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 heating and burning. There are 6 arched openings on the outer wall of the middle chamber for placing glass crucibles.
After putting it in, these openings were 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 from 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 with 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 is added between the inner bricks and the outer bricks.
Insulation bricks greatly increase 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 above 1200C, although they knew from technical literature that this type of glass furnace does not require a preheating chamber, Ji Situi and others could not guarantee that it would be usable.
From a different perspective, a ceramic pipe is added to the highest outdoor space 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 team and the mechanical team jointly began firing glass experiments. The first firing process lasted 10 hours, and finally the solid raw materials in the crucible 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, manganese dioxide can be added to make it transparent." Li Di was confident, "But everyone's blowing skills are really bad. You need to practice more."
"Manganese dioxide, can you change it?" Xiao Bailang said dissatisfied.
"That's all I knew about this." Li Di really didn't know where they could find the manganese dioxide.
"Well, actually you don't need manganese dioxide," Ji Situi said. "It acts as an oxidant, not necessarily manganese dioxide. Potassium nitrate is also an oxidant. Add this."
The so-called potassium nitrate is saltpeter, and they still have a lot of this stuff. After trying a few more times, the glass test team finally made colorless glass the day before New Year's Eve. This success made many people in the industrial sector cheer: Time Travel
