Chapter 820: Refine, teach art!

"Master, you are finally here~!"

Qiquge’s new workshop in Meicun finally welcomed its owner today. Speaking of

Li Zexuan’s boss, he was really unqualified. He didn’t even bother about the

expansion of the workshop from beginning to end. , He gave full power to Fu

Bo, and after the completion of the new factory, he had never been there from

start to finish, so in the afternoon, Fu Bo saw Li Zexuan who suddenly

arrived, which was both sorrow and surprise.

A slight embarrassment appeared on Li Zexuan's face. Obviously he also heard

the profound meaning of Fu Bo's words, "Ahem, Fu Bo, long time no see! How

good are you all these days~?"

Fu Bo glanced at Li Zexuan, and sighed helplessly. He knew that Li Zexuan had

been doing a lot of things recently, so he didn't blame too much. Moreover, Li

Zexuan has always respected the old people in their workshops, so Fu Bo also

did. I have always regarded Li Zexuan as a junior, "I am worried about the

young master, the old man is okay, and he can help the young master manage the

workshop for another two years!"

Uncle Fu led Li Zexuan into the workshop, while answering Li Zexuan's question

just now.

After hearing this, Li Zexuan frowned. He suddenly remembered something. Fubo

is now old, and even if he is not sick or disaster-free, he will be able to

work in the workshop for at most two or three years. To take over? Who will

stir up this big beam?

Successor, successor, you have to pay attention to one successor to Fober from

now on!

Li Zexuan said with emotion in his heart.

The new workshop of Qiqu Pavilion covers a huge area, occupying nearly 100

acres in total. The workshop in Chang'an is dozens of times larger. According

to different regional functions and different types of items produced, the

workshop is divided into ten areas. The production area has a large factory

building similar to modern ones, the office area has an office building, and

the living area has a dormitory. It can be said that this new worker The

workshop, which covers almost all the elements, is regarded as the most

comprehensive workshop in the entire Datang.

"Oh, yes, master, you brought so many buckets of white pulp yesterday. What is

the purpose of keeping them? The warehouse of our workshop is almost filled

with those things~!"

Fu Bo planned to take Li Zexuan to the office area to sit for a while. When he

walked halfway, he suddenly remembered the thousands of barrels of white pulp

sent by the Wang family's fleet yesterday, so he turned to ask.

Li Zexuan smiled slightly and said, "That thing is called rubber, which is

precious! So much rubber should be more valuable than our workshop! Don't

worry, I am here to teach you how to use it today? "

When Uncle Fu heard it, he felt a little unbelievable. He had already inquired

from elsewhere today that Li Zexuan had bought these rubbers, which cost a

total of 8,000 sticks. Even if these rubbers could bring ten times the profit

to the workshop, it would only be 80,000 sticks. How could it be worth more

than the entire workshop?

"That's right! The old man is trying to see, what can these things like soy

milk be used for?"

Seeing what Li Zexuan said, even though Fubo didn't believe it in his heart,

he still wanted to see it.

"Hehe~! Let's go to the workshop next to us, Uncle Fu, you have someone bring

a bucket of rubber over! Oh, by the way, another big pot of white vinegar~!

Li Zexuan pointed to the large workshop next to him and said to Fu Bo.

"okay!"

Although Uncle Fu wondered why Li Zexuan was jealous, he still nodded and

agreed, and ordered the people below to start to do the same.

………………………

After a while, all the items were ready, and Fubo also brought a few old

craftsmen from the workshops to observe.

"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 to anneal the blacksmith's gate, but he

was in a hurry. At this moment, Li Zexuan couldn't find a more suitable

container.

"Yes, Master~!"

Song Xiaosi responded, and quickly joined Pang Feiji to lift the big wooden

barrel full of rubber, and the white flowered rubber latex poured down into

the sink. This thing looks so sparse and really like soy milk. Similarly, it's

no wonder that Fober couldn't think of the purpose of this thing.

"Well, pour all this pot of vinegar in again!"

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

ordered.

A very important process in the extraction of rubber latex 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 lowering 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 electrokinetic potential is zero, and the

rubber particles Without repulsion, they gather together and solidify into

blocks.

In the 21st century, most foreign countries use formic acid as a coagulant,

while domestically, acetic acid is mainly used as a coagulant. The specific

acid selected is different, the properties of the glue obtained will be

different. These knowledge points ~www.mtlnovel.com~ were all learned by Li

Zexuan in the factory of the local tyrant classmate in his previous life. How

else would he understand this?

In the Tang Dynasty, formic acid definitely did not exist, but acetic acid

did! Because of the so-called acetic acid, it also has a very popular name,

which is acetic acid. Vinegar contains a lot of acetic acid! This is also due

to the wisdom of our ancestors, who first invented vinegar, otherwise Li

Zexuan would have to make vinegar now.

"Now you two go get two hoes, wash them with hot water, and then take them and

stir them in there~!"

Li Zexuan quickly ordered.

Song Xiaosi and Pang Feiji led their orders. After a while, the two of them

came in with a smooth hoe. Under Li Zexuan’s demonstration, they began to put

sticks in the stone trough. Stir up.

"Hey hey, Patriarch! It's solidified, solidified! It was just like soy milk,

but now it's tofu~!"

After stirring for about two quarters of an hour, Pang Feiji suddenly

exclaimed in surprise.

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

Song Xiaosi was also very excited.

Don’t need him to say, Fubo and the other craftsmen have already gotten

together. Since the rubber latex was sparsely smashed, it has become like tofu

at this moment, Fubo couldn’t help but wonder:

"Hey~! It's really strange! Didn't it just pour a pot of vinegar into it? How

come all the rubber has solidified?"

"Yeah! This is so weird, it's like a conjure! If it weren't for seeing it with

your own eyes, it would be incredible!"

The rest of the craftsmen were also shocked. Those who hadn't studied

chemistry can only classify it as a trick.
