"Young master, you're finally here~!"

The new workshop of Qiqu Pavilion in Meicun finally ushered in its owner today, speaking of Li Zexuan, who is the boss, is really not qualified at all, the expansion of the workshop, from beginning to end, he didn't ask at all, and gave it to Fu Bo, and after the new factory was completed, he had not been here from beginning to end, so Fu Bo saw Li Zexuan who suddenly arrived in the afternoon, which was both resentful and surprised.

A slightly embarrassed look appeared on Li Zexuan's face, obviously he also heard the deep meaning of Fu Bo's words, "Ahem, Fu Bo, long time no see!" Have you been in good health lately~? ”

Fu Bo glanced at Li Zexuan and sighed helplessly, he knew that Li Zexuan had a lot of things to do recently, so he didn't blame him too much, and Li Zexuan has always respected the old people in the workshop, so Fu Bo has always treated Li Zexuan as a junior, "Worry about the young master, the old man is fine, and he can help the young master manage the workshop for another two years!" ”

Fu Bo led Li Zexuan to the workshop, and at the same time answered Li Zexuan's question just now.

After hearing this, Li Zexuan suddenly frowned, he suddenly remembered something, Fu Bo is old now, even if he is free of illness and disaster, he can work in the workshop for two or three years at most, so who will take over at that time? Who will pick up this girder?

Successor, successor, we have to keep an eye on a successor for Fauber from now on!

Li Zexuan sighed in his heart.

The new workshop of Qiqu Pavilion covers a very large area, occupying a total of nearly 100 acres, and the workshop in Chang'an is dozens of times larger. According to the different functions of the area and the different types of items produced, the workshop is divided into ten areas, the production area has a large factory building similar to the modern one, the office area has an office building, and the living area has a dormitory.

"Oh, by the way, young master, you asked people to move so many barrels of white pulp yesterday, what is the purpose of keeping it? The warehouse of our workshop is almost filled with those things~! ”

Fu Bo was going to take Li Zexuan to the office area to sit and rest for a while, and when he was halfway there, he suddenly remembered the thousands of barrels of white pulp that the Wang family's fleet sent yesterday, so he turned his head and asked.

Li Zexuan smiled slightly and said, "That thing is called rubber, but it's precious!" So much rubber, it should be worth more than our workshop! Don't worry, didn't I come here today to teach you how to use it? ”

When Fu Bo heard this, he felt a little incredible, he had already heard from elsewhere today that Li Zexuan bought these rubbers, and he spent a total of 8,000 yuan, even if these rubber can bring ten times the profit to the workshop, it is only 80,000 yuan, how can it be worth more than the entire workshop?

"That's right! The old man is trying to see what these things like soy milk can be used for? ”

Seeing what Li Zexuan said, although Fu Bo didn't believe it in his heart, he still wanted to take a look.

"Hehe~! Then let's go to the workshop next to it, Fauber, you have someone carry a bucket of rubber! Oh, and by the way, a big pot of white vinegar~! ”

Li Zexuan pointed to the big factory next to him and said to Fu Bo.

"Well, good!"

Although Fu Bo wondered why Li Zexuan was jealous, he still nodded and agreed, and instructed the people below to start doing the same.

………………………

After a while, everything was ready, and Fauber brought several old craftsmen from the workshop to watch.

"Song Xiaosi, Pang Feiji, you pour this bucket of rubber into the stone trough!"

Li Zexuan pointed to the rectangular stone trough in front of him and instructed Song Xiaosi and Pang Feiji behind him.

This stone trough was originally used for annealing when the blacksmith door was striking iron, but the matter was in a hurry, and Li Zexuan did not find any more suitable container for this while.

"Yes, young master~!"

Song Xiaosi responded, and hurriedly followed Pang Feiji to lift up the big wooden barrel full of rubber, and the white rubber latex suddenly poured down into the sink, this thing looks really thin like soy milk, no wonder Fu Bo can't think of the use of this thing.

"Well, pour all the vinegar into it!"

Li Zexuan weighed the weight of the pot of white vinegar next to him, and then ordered.

In the refining of rubber latex, a very important process is curing. In the modern rubber latex curing process, the most commonly used curing agents are formic acid and acetic acid.

Because formic acid and acetic acid can increase the amount of hydrogen ions in the latex, thereby reducing the pH value of the latex, compressing the electric double layer, and thinning the hydration film, when the isoelectric point of the protein is reached, the electromotive potential is zero, and there is no repulsion between the rubber particles, and they gather with each other and solidify into a block.

In the 21st century, formic acid is mostly used as a coagulant in foreign countries, while acetic acid is mainly used as a coagulant in China. The specific acid used is different, and the glue performance will be different. These knowledge points are all what Li Zexuan learned in the factory of the local tyrant's classmate in his previous life, otherwise how would he understand this?

In the Tang Dynasty, formic acid certainly didn't exist, but acetic acid did! Because of the so-called acetic acid, it also has a very popular name, that is, acetic acid, and table vinegar contains a lot of acetic acid! This is also thanks to the wisdom of our ancestors, who took the lead in inventing vinegar, otherwise Li Zexuan would have to make vinegar at this time.

"You two go and get two hoes now, wash them with hot water, and then quickly bring them over and stir them vigorously in it~!"

Li Zexuan hurriedly ordered.

Song Xiaosi and Pang Feiji took the order and left, and after a while, the two of them walked in with a smooth hoe, and under Li Zexuan's demonstration, they began to stir hard with sticks in the stone trough.

"Hey, hey, master! Solidified, solidified! It was the same as soy milk just now, but now it's turned into tofu~! ”

After about two quarters of an hour, Pang Feiji suddenly shouted in surprise.

"It's really turned into tofu, come and see~!"

Song Xiaosi was also very excited.

There is no need for him to say, Fu Bo and the rest of the craftsmen have already come up, since the rubber latex that looked like a sparse noise before has become the same as tofu at this moment, Fu Bo couldn't help but sigh in amazement:

"Hey~! It's weird! Isn't it just a pot of vinegar poured into it? Why did all this rubber solidify? ”

"Yes! It's so weird, it's like juggling! If you hadn't seen it with your own eyes, it would have been incredible! ”

The rest of the craftsmen were also shocked, and they had no idea how to react, so they could only classify it as a trick.
