Lord of Industrialization

Frederick asked Schmidt and others to slowly debug the machine, while he and Koehler looked at the paper being trial-produced.

What do you think of those two machines? asked Frederick.

Koehler replied: I think it's very good. Schmidt is also willing to give it on credit. He said it was done with the school's research funds and can be paid back over time.

The corners of Frederick's mouth twitched.

As they walked over to a pile of thumb-sized wood chips, Koehler said: These are cut with a saw, which is very time-consuming and labor-intensive compared to machines.

Frederick nodded, squatted next to the wood chips, picked them up and observed.

Koehler continued: The reason why the paper we produced last time turned gray was found because the pine bark in the wood chips was not cleaned.

Schmidt's machine can just remove the bark first, so that the paper can be whiter later.

Frederick nodded, stood up, and went to the side to watch the workers picking wood, taking out all the dark ones.

The thin wood chips that were picked out were taken to the stove outside and steamed in a large pressure cooker.

Frederick found that the workers poured the water after steaming the pine wood in the pressure cooker into a water tank to collect it, and put the lid on it. He asked curiously: What is this doing?

The water in which the pine chips are cooked contains pine oil, which is an unexpected by-product and can be used in printing ink, Koehler explains.

Frederick nodded with satisfaction. This was not the case before. In the beginning, Psyche's method was to steam steamed buns over water, but now he steamed them in a large pressure cooker, which reduced a lot of time. He was very satisfied that they could do it. Give full play to subjective initiative.

The same goes for the subsequent acid cooking process. The thin wood chips and diluted slime acid are no longer cooked directly in a clay pot. Instead, the clay pot is covered with a lid and placed in a pressure cooker over water for heating. The time is changed from the original three The hour was reduced to one hour.

During the acid washing stage of wood chips, Koehler said apologetically: It stands to reason that part of the used acid can be reused, but we haven't found a way yet.

Frederick said calmly: It doesn't matter, you can study it slowly.

Wastewater and waste residue must be treated well. The amount is still small and cannot be seen now. In the future, when the scale increases, the entire river may not be needed.

In his previous life, he had seen the harm caused by industrial pollution in the 1980s and 1990s. It was no joke that a small factory killed animals and plants in a river.

Koehler immediately nodded and took note.

In the refining stage, several stone mills have used magic reciprocators as power, which is much more efficient than hydraulic power.

Frederick saw a few young students recording various data at the place where additives were added to the paper pulp, so he went over to take a look.

Koehler explains: “We record every process, every recipe and the result, ready to find the best from them.”

Last time we found that the printed paper was still very rough. After discussion, we felt that there were still gaps in the wood fibers, so we decided to add some finer grass fiber fillings, which had a good effect.

Frederick said with great satisfaction: Very good, very good. This is very good.

Different papers are used in different places. Once you master the rules, you can meet different needs.

Next to the papermaking trough, several workers skillfully used dipnets to scoop up the pulp.

Koehler took a copy net to show to Frederick and said distressedly: Now we use a net made of copper wire, which will leave marks on the paper.

Frederick smiled and said to him: There is nothing we can do about it, but it doesn't matter. Just adjust the distance of the marks and treat it as your own line.

Koehler shrugged and said, That's all I can think of.

Frederick took the papermaking frame and studied it, and said thoughtfully: I think we can use thin copper wire to weave a pattern on it and leave a mark on the finished paper, so that customers will know which paper is our product. ”

Koehler was stunned for a moment, then thought about it and asked, What pattern do you plan to use?

Frederick frowned and thought for a moment. Trademarks these days mostly use animals and plants to represent them. Nowadays, many animals and plants are used. How about durian?

The problem is that probably only Psyche and Mrs. Sophie have seen this thing here. Mrs. Sophie's logbook was empty for a few days. Later, she said it was because some sailors got a few huge ones when they went ashore to look for fresh water. The devil fruit covered in thorns returned to the ship.

He finally chose a traditional pattern, used magic elements to draw a in the air, and then said: Use a simple drawing of a castle, and add a quill in the middle.

Koehler thought it was okay, so he wrote it down.

The paper taken out from the copy net is first squeezed to squeeze out some water, and then put into the first roller dehydrator for dehydration. This dehydrator has a very smooth conveyor belt made of slime glue, which transfers the paper to two A large amount of water is pressed out between the smooth hard rubber rollers, and then placed in the next dehydrator to use smooth steel rollers to press out the water and make it smoother.

This machine was also made by Schmidt, Koehler said. It was said that it was modified from a machine that already existed in the blacksmith shop.

Frederick nodded and said, Yes, these two rolling mills, which were originally supposed to make steel plates, were replaced with less powerful power sources. It would be good to use them here.

The steel rolling machine from the blacksmith shop was obtained, because the manual rolling mill used by jewelry craftsmen to roll gold, silver, and lead sheets was used as a reference. Everyone just enlarged and strengthened the parts, and finally succeeded after taking some detours.

The two dehydrators in front of us are actually made of recycled waste products. Their frames and screws are not strong enough in front of steel, but they are easy to deal with paper.

Frederick suddenly thought that the roller used in the rotary cutting machine for cutting wood just now should also be the product of a detour.

At that time, it was difficult to cast and forge such a long steel roller at one time, as the surface would be uneven, so someone proposed to assemble it in sections, but it later failed.

Frederick looked around and then went to Katie's office with Koehler.

It's like a laboratory, with shelves on the walls filled with colorful bottles and jars.

Are you back from playing? Katie was mixing ink, Are you hungry?

The corners of Frederick's mouth curled up, and he found that her cheeks had been smeared with a rosy red color at some point.

It's such a mess here, Frederick said quickly, I'm going to Koehler's office.

After saying that, he gave Koehler a wink, and then ran away with Tarot, who had been following quietly.

When Katie appeared in front of Frederick again, her face was clean, and she pinched Frederick's cheek angrily. Frederick immediately felt that her fingers were greasy.

Talma, who was on the side, immediately took out a handkerchief and helped Frederick wipe the ink on his face. He didn't wipe it clean at once and rubbed it hard several times until his face turned red.

Koehler suppressed a smile when he saw this and turned his head away from the legendary genius principal.

Frederick pouted and pulled Katie towards the printing place.
