Chapter 804: 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 ~EbookFREE.me~ 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.

First!
