Just like Liu Yan said, he is engaged in technology, and he has the highest qualifications in a workshop like Beijing.

That's also a big bull in the industry.

It's normal to be arrogant.

Xiang Yan said to Xiang Yuyue:

"In the field I am most familiar with, it is normal to hear a layman say something that clearly violates the common sense of the industry, and he can't help but ridicule."

"This is determined by the limitations of the individual person, and it has nothing to do with good or evil, and it is not a big deal."

"He didn't make any big mistakes, he just didn't know enough."

"It's not a big deal."

Then Xiang Yan said to Zhu Laosan:

"Okay, it's okay, you go and get busy with yours."

I didn't want to be familiar with Zhu Laosan.

But I didn't expect this Zhu Laosan to mumble before leaving:

"I don't want to think about why all the papermaking workshops in the world use bamboo as raw materials. There are some things, it's not something that you can mess around with just your imagination~"

Xiang Yan suddenly frowned.

But as soon as he said that he was fine, let him go, and it was not good to have a seizure.

And he spared him one last time.

Then he said to himself in his heart, it's okay, after all, the prime minister can hold the boat in his belly.

After the bamboo, which had been soaked in the pond for enough time, was fished out by the workers.

Xiang Yan and Xiang Yuyue watched as they transferred the bamboo to some huge barrels.

Then I saw some other workers who had been preparing here for a long time and put lime into it.

Xiang Yan explained to Xiang Yuyue:

"This step of boiling the bamboo and lime together lasted for eight days and eight nights."

"Wow......"

Xiang Yuyue still exclaimed, "Although soaking in the pond for 100 days before is enough to span a long time, the process of boiling for eight days and eight nights here is also very exaggerated." ”

Liu Yan is very discerning, and it is impossible for the two masters to wait here for eight days to see the next steps.

So he said to Xiang Yan and the others:

"Childe, Miss, there is already bamboo cooked in advance over there, and the next step is to crush the bamboo in the nest, please follow me to see it."

After reading the first three steps, the back is some simple processes, and after a casual look, Xiang Yan took Xiang Yuyue back to the Right Prime Minister's Mansion.

After going back, Xiang Yan went directly to the old housekeeper Yang, opened a list for him, and asked him to buy a copy according to the list.

Speaking of which, since returning to the capital, this is the first time to find an old housekeeper Yang.

It is really overkill to let him do this kind of procurement.

But it's a pity that the two parts of the work of providing force protection and intelligence support have been replaced by Xiang Yuyue.

So he can only be asked to do some such simple things.

That's right, although Xiang Yuyue is a female streamer, if you really want to fight, Xiang Yan is really not the opponent of Xiang Yuyue, who has practiced martial arts since childhood.

Therefore, to protect this piece by force, in turn, Xiang Yan has to rely on this heroine's second aunt.

The things were quickly bought, and Xiang Yuyue saw Xiang Yan making a lot of bottles and jars, pouring the solution in one jar into another jar for a while, and then looking at the solution mixed together in the two jars thoughtfully.

Then he added hemp skin to it.

One will be delighted, the other will be frowned.

Xiang Yuyue couldn't help but ask:

"Xiang Yan, what are you doing?"

Xiang Yan didn't raise his head, so he replied attentively:

"Didn't you say you wanted to improve the raw materials for papermaking?"

"Paper, in the paper dictionary compiled in the United States, defines paper as a thin sheet of plant fibers.

Later, after the innovation of papermaking, the definition was changed to "a thin sheet of various fibers".

So the focus is on fiber.

I'm going to replace bamboo with hemp skin, which also contains a lot of fiber.

I'm now experimenting with solutions that can soften and preliminarily degum the hemp skin.

Makes the hemp fibers shorter and easier to degum. ”

Xiang Yuyue asked:

"With hemp skin, you don't have to soak in the pool for a hundred days like bamboo?"

Xiang Yan said: "Yes. ”

"As long as the right solution is debugged and the right raw materials are selected, the first step can even be shortened to a few days or just one day!

Isn't that a big step forward? ”

The debugging solution in the first step didn't cost Xiang Yan much time.

After all, he knew the principle before, and what he is doing now is to find some ancient material substitutes that can replace some industrial products in later generations.

It didn't take long for them to try them out one by one.

"By the way, second aunt, do you know what gray water is?" Xiang Yan asked.

"Greywater?" Xiang Yuyue asked, "Is it to be used in the next steps?" ”

"Yes." Xiang Yan said, "After the hemp skin treated in the step just now, it should be soaked in gray water to play the role of degumming, dispersing fibers and bleaching. ”

The third step is to pound, in order to enhance the firmness of the paper.

After pounding, it is washed.

Wash repeatedly with plenty of water to wash off the mortar and impurities and increase the whiteness of the paper.

This step didn't have much technical content, so Xiang Yan could let Xiang Yuyue do it for her, and then move on to the next step by herself.

Slotting.

The pulp in the paper trough is beaten evenly with a wooden stick, so that the pulp fibers float evenly in the paper trough.

This has to be Xiang Yan herself, after all, it is manual work, Xiang Yuyue must not do as well as a man like herself.

The two of them washed one and the other beat, which has the taste of male farmers and women weaving in a small peasant economy.

Originally, these simple manual jobs could be done by the subordinates in the house.

But in order to make the process controllable and try out all possible mistakes.

Therefore, Xiang Yan has to get started in person, so that it is convenient to formulate operating specifications for the workshop later.

Industrial production must be standardized.

This is not only for safe production, but also for the quality of the products produced.

After the slotting is completed, the next step is papermaking.

The so-called papermaking is to use the papermaking mold frame to pick up the pulp in the paper groove and leave it evenly on the papermaking mold frame.

After that, the picked up pulp is taken to a ventilated place to dry.

After drying, the paper is torn off the papermaking mold frame, and a simple piece of hemp paper is made.

Xiang Yan and Xiang Yuyue were busy all day, and the dried paper was all over the yard.

Fortunately, this courtyard is exclusive to Xiang Yan, and usually only Xiang Yuyue and him use it.

Otherwise, there really wouldn't be a place to put these experiments.

Xiang Yuyue looked at the work results of the courtyard, and suddenly felt a sense of pride.

"Ah, I've worked really hard today, I can eat one more bowl of rice tonight!"

Xiang Yan couldn't help but laugh:

"Thanks to your help today, I wouldn't have been able to make this first batch of experiments on my own in one day.

Let's go, it's still the third aunt's Yuxiang Building, I'll please! ”

"Yay!" Xiang Yuyue was suddenly elated.

Xiang Guozhong, who happened to come over and was about to call the two of them to eat, heard this, and immediately complained to Xiang Yan:

"Little stone, you're a little biased, I don't see you invite your old son to eat outside, and go out with your second aunt every day to open a small stove!"
