Compared with last winter, materials were scarce in the city and the scale of papermaking had not expanded. Now it is different. Now in the wilderness, vegetation grows wildly and papermaking materials are endless. Not only that, when the method of making wood from tree trunks is cracked,

After solving the technical problems of slurry, the sources of materials became more abundant.

The trunk of a big tree that is seven or eight years old weighs three to five hundred kilograms. If these three to five hundred kilograms of wood are used to make paper, tens of thousands of sheets of high-quality paper can be made.

With tree trunks, bark, and inexhaustible herbal materials, there is no limit to the materials, and there is no limit to the paper output. As long as the manpower is sufficient, ten thousand sheets of paper, one hundred thousand sheets, or one million sheets of paper can be made a day.

It's all possible.

It is said that if a worker wants to do his job well, he must first sharpen his tools. To achieve the terrifying production capacity of one million sheets of paper per day, this requires the use of at least thousands of people. If the papermaking base is built near the river, it will need to be built near the river.

Build homes for thousands of papermakers and provide them with all their daily necessities.

The technical steps of papermaking include drying of materials, crushing of materials, boiling of materials, removal of impurities and decolorization, pulping and papermaking, drying, cutting, and storage.

To dry the materials, you only need to find an open space to spread the materials out and expose them to the sun.

For the crushing of materials, if bark and herbs are crushed, at least one guillotine is needed. To use the guillotine efficiently, at least two people are needed.

The bark and some grasses are tough in nature and may need to be crushed using vertical mills or stone mills. Whether they are ground or ground, this requires human and animal power.

The most troublesome thing is to deal with the trunk. The trunk is so solid that it cannot be struck with a guillotine or cut with scissors. It is also very laborious to chop with an axe.

After much thought, there is no good way to crush tree trunks.

Considering that the whole tree trunk is an important building material, the whole tree trunk can be used as beams and rafters for houses, and can also be sawn into planks for building ships and cars. The whole log has a wide range of uses, so there are more

Economic arrangement.

A more economical arrangement is to set up upstream and downstream industries. After the trees are cut down, the trunks are first sent to the carpentry camp. The carpentry camp uses the entire tree to build houses, build cars and ships. Then, during the process of building cars and ships,

, During various planing and cutting processes, a large amount of wood chips will definitely be produced. These wood chips have no use except burning them elsewhere. They can just be sent to the papermaking base for papermaking.

According to this arrangement, the problem that needs to be solved is to concentrate the industry as much as possible. It is best to gather all the woodworkers in one place. In this way, it will be convenient and quick to collect sawdust and remaining materials for processing.

In order to reduce pollution and facilitate water access, the papermaking industry must be located by the river. The shipbuilding industry among the woodworking industries must also be located by the river. Moreover, there is sufficient water power by the river. Water-powered mills, water-powered forging hammers, etc. will also require carpentry.

They spent long hours involved in the construction.

Also, the isinglass required for woodworking must be obtained from the body of fish. To obtain isinglass, you must catch fish. Fishing cannot be separated from water. After catching fish, killing them and scraping their scales is also inseparable from water.

Taking into account various industries, including the fish industry, shipbuilding industry, glue making, wood industry, paper making industry, as well as water-powered mills and water-powered forging hammers, the entire industrial chain must be built on water.

The largest water vein near Julu County is a branch of the Laozhang River fifty miles away. It is not far away. It can be considered that there may be a war in the near future. In the event of a war, a large number of manpower will inevitably be out of sight. Therefore, along the

Plans to build a workshop in River had to be postponed.

To make paper, medicine is an indispensable core key.

The method of making strong alkali is to mix and concentrate the plant ash solution and lime water solution for extraction.

In the process of making medicines, plant ash solution and lime water solution are common materials, and the mixing steps of the two liquids are also simple. Considering the confidentiality as much as possible, the solution mixing stage can be left to civilians to operate, but after the solution is mixed, it must be moved to the dark

It is the responsibility of a dedicated person.

Judging from current practice, one hundred jars of mixed solution will eventually extract one and a half bowls of strong alkali powder. Such a small amount of extraction requires a lot of processing.

The production of strong alkali can only be done manually at present. It can only be produced by mixing plant ash solution and lime water solution. It is not difficult to prepare the plant ash solution and the lime water solution. However, it can only be evaporated, concentrated and extracted, which is time-consuming and laborious.

Not long ago, when preparing medicine, we were worried that too high a water temperature would destroy the properties of the medicine, so we had to boil it at low temperature. However, the low temperature was difficult to control. So we used electric hair dryers and came up with the hot air evaporation method.

If you want to extract strong alkali on a large scale, you can dig a wide pit on the ground and cover the bottom with stones or ceramic bricks. Then, pour barrels of mixed solution of plant ash, lime and water into it, and then use dozens of hot air devices.

By blowing hot air into the pit, strong alkali powder can be produced in large quantities with extremely high efficiency.

The southern half of Julu City is divided into industrial areas. In the innermost corner of the southern half of the city, craftsmen dug many huge pools on the ground. Each pool is very large and wide, but not very deep.

The craftsmen used big stones to pound the bottom of the pool firmly and flattening it in preparation for the subsequent process.

After the foundation of the pool is laid, masons will come and build the pool into a slope shape with one side high and one side low. In this way, when the solution is evaporated, the solution in the pool will slowly flow to the low-lying areas due to the height difference, allowing the medicine to be released.

Easy to collect.

This set of evaporation ponds can be further improved by digging a hole in the lowest part of the pond and plugging a wooden plug. When the solution in the pond is concentrated to the end, the plug can be pulled out and the concentrated alkali solution can be directed to the pottery urn.

Then heat it and boil it, and the medicine will be precipitated quickly.

This system combines the best of both the sun salt method and the salt boiling method.

The sun salt method is easy to produce and has a large production scale, but the cycle is long and requires light and weather conditions. If you are located at the seaside, you can also use the sun salt method to prepare strong alkali. However, Julu is located inland and does not have sufficient sunlight.

The salt method is not enough.

Following the principle of sun salt, the hot air evaporation method can also achieve the same effect as sunlight.

This chapter is not over yet, please click on the next page to continue reading! Another method is the salt boiling method. It takes half a month to expose a pot of salt water to the sun and boil it with firewood. The salt can be boiled out in a few hours. Boiling

Although the salt method is fast, it consumes a lot of firewood.

Therefore, taking the best of both worlds into account, the alkali solution is first evaporated by hot air, concentrated and then boiled. This can greatly save fuel and greatly increase the speed of drug preparation.

In fact, there is another way to be more efficient and energy-saving.

The basic reason why you can dry salt on the coast but not inland is because there is insufficient sunlight in the interior. On the other hand, if you can gather the less strong sunlight in the interior, you can also dry salt inland.

The method of condensing light can be a glass convex lens or something, or you can use a metal mirror or a metal concave mirror made of copper.

The energy of light is very strong. If we make glass and then make cheap mirrors, make several mirrors as big as walls, and use the mirrors to focus the light into the pool, then at this time, the ratio of the light received in the pool will be

The seaside is several times stronger, so the alkaline solution can be boiled out quickly without using any fuel.

No matter how expensive the glass or the mirror is, there is no cost if it cannot support the light. It takes one month to produce the mirror and the cost of the mirror is higher than that of firewood. After two months, the cost of the mirror is still high. By one year, the cost of the firewood consumed is already higher than that of firewood.

The cost of the mirror is up.

Then in the future, the condenser can continue to be used for many years. In subsequent use, it will be used for several years at zero cost.

Regarding the manufacturing of glass, I vaguely remember that the Sumerians or people there once were transporting baking soda by ship. The ship encountered a storm and had to dock for repairs. The crew made a fire on the coast to cook.

Sometimes, I accidentally burned some shiny things.

These shiny things are glass. The principle behind the birth of glass is that after baking soda is added to sand and calcined, glass is produced.

Sand is easy to find and calcining is not difficult. If the temperature is not enough, you can find a place to buy coal to make coke in the future. With the coke, the temperature will not be a problem.

[A book-chasing app recommended to me by an old book friend I have known for ten years, Yeguoyuedu! It is so easy to use. I rely on this app to read and listen to books while driving and before going to bed. You can download it here.yeguoyuedu]

Only baking soda. I don’t know what baking soda is. I vaguely remember that baking soda is edible alkali. Baking soda is a naturally occurring mineral. Since it is a naturally occurring mineral, it means that it may be naturally distributed. If you can find baking soda

From the production area, you only need to buy a few cars to make glass.

There must be coal-producing areas in Han Dynasty, but the presence or absence of baking soda is uncertain. The only factor that restricts the manufacture of glass is baking soda.

In addition to soda-fired glass, in the Central Plains, colored glaze could be made as early as the Spring and Autumn Period and the Warring States Period, and colored glaze is an opaque glass.

Perhaps because the temperature was not enough or the material was not pure enough, craftsmen in the Spring and Autumn and Warring States periods were unable to produce transparent glass.

However, as long as there is a process, whether the temperature is not enough or the purity is not enough, it is not difficult to improve.

If the temperature is not enough for coke and the purity is not enough, then extract it. The extraction method is to add acid, alkali, and salt and try various materials. You can always find a method.

It is known that the Han Dynasty had the technology of firing colored glaze. Since there was the technology of firing colored glaze, the technical basis for firing glass also existed.

Li Mengxi summoned all the craftsmen and asked who knew how to make colored glaze. As a result, no one knew how to make colored glaze.

It seems that the art of firing colored glaze is an advanced craft, and it is possible that only in prosperous places can relevant craftsmen be found.

The prosperous place, Luoyang, there is nothing more prosperous than Luoyang in the world.

It seems that I have time to send someone to Luoyang to recruit some skilled craftsmen.

One thing made Li Mengxi particularly curious. Since baking soda is soda ash, can this alkali be synthesized artificially?

Anyway, not long ago, Shilihu Tu used plant ash and lime water to synthesize a super strong alkali. It is known that alkali can be synthesized.

Baking soda, Li Mengxi knows, is an edible alkali. The reason why baking soda is edible is because when you add a little baking soda to the dough, the baking soda will release carbon dioxide gas after being decomposed by heat, making the dough loose and porous.

.

Carbon dioxide will be released, so there must be carbonic acid radicals in baking soda. Just like carbonated drinks, carbonated drinks will also produce carbon dioxide when decomposed by heat.

Half of the ingredients of baking soda have been determined. Li Mengxi wrote on the paper, [co3], which is carbonate.

However, what Li Mengxi doesn't understand is that carbonate is acidic, why is baking soda a edible alkali, and why is it called an alkali.

Having carbonate, also known as a base, is very strange.

Li Mengxi was teaching Xiao Bian how to draw, mostly simple things like leaves and grass. Li Mengxi knew advanced sketching techniques, such as shading and lines, but he didn't want his brother to master them prematurely.

These.

Children's imagination is the most important. It should be done step by step and not overthrow.

After drawing for a while, Xiao Zhuan showed the graffiti to Li Mengxi. Xiao Zhuan must have thought that he had done a good job and looked proud.

Li Mengxi looked at it pretendingly for a while, commented for a while, and praised his brother very much.

Putting down the drawing paper, Li Mengxi asked, "Xiao Bian, how many days have you not been to class?"

"I don't want to go to class." Xiao Zhuan said.

Li Mengxi was helpless. He returned to painting and couldn't delay his business.

Li Mengxi had no choice but to patiently persuade Xiao Brick to go back to class and start painting again when he was free.
