"Master, you are finally here~!"
Qiquge's new workshop in Meicun finally welcomed its owner today. Speaking of Li Zexuan, the boss, he is really not qualified at all. From beginning to end, he had no involvement in the expansion of the workshop. , full power was given to Uncle Fu, and since the new factory was built, he had not been here yet. Therefore, when Uncle Fu saw Li Zexuan who suddenly arrived in the afternoon, he was both resentful and surprised.
A slightly embarrassed look appeared on Li Zexuan's face. Apparently he heard the deeper meaning of Uncle Fu's words, "Ahem, Uncle Fu, long time no see! How are you doing lately~?"
Uncle Fu glanced at Li Zexuan and sighed helplessly. He knew that Li Zexuan had been busy recently, so he didn't blame him too much. Moreover, Li Zexuan had always respected the old people in the workshop, so Uncle Fu also He has always treated Li Zexuan as a junior, "Young Master is worried about me, I am in good health, and I can still help you manage the workshop for another two years!"
Uncle Fu led Li Zexuan into the workshop and at the same time answered Li Zexuan's question.
After hearing this, Li Zexuan frowned immediately. He suddenly remembered something. Uncle Fu is now old. Even if he is not sick and has no disasters, he can only work in the workshop for two or three years at most. Then who will do it? Come to take over? Who will take up this important role?
Successor, successor, I have to look out for a successor for Uncle Forbes from now on!
Li Zexuan sighed in his heart.
Qiquge's new workshop covers a very large area, covering nearly a hundred acres in total. The Chang'an workshop 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 long factory building similar to modern times, the office area has office buildings, and the living area has dormitories. It can be said that this new factory The workshop covers almost all elements and is considered to be the most comprehensive workshop in the entire Tang Dynasty.
"Oh, by the way, Master, you had so many barrels of white slurry brought in yesterday, for what purpose did you keep them? The warehouse of our workshop is almost full of those things~!"
Uncle Fu planned to take Li Zexuan to the office area to sit and rest for a while. Halfway there, he suddenly remembered the thousands of barrels of white pulp delivered by the Wang family's fleet yesterday, so he turned around and asked.
Li Zexuan smiled slightly and said: "That thing is called rubber, and it's so precious! That much rubber should be worth more than our workshop together! Don't worry, didn't I come here today to teach you how to use it? "
When Uncle Fu heard this, he felt a little incredible. He had already found out from elsewhere today that Li Zexuan had bought these rubbers and spent a total of 8,000 guan. Even if these rubbers could bring ten times the profit to the workshop, it would only be 80,000 guan. , how could it be worth more than the entire workshop?
"That's just right! I just want to see what these things like soy milk can be used for?"
Seeing Li Zexuan's promise, even though Uncle Fu didn't believe it in his heart, he still wanted to take a look.
"Haha~! Then let's go to the workshop next to it. Uncle Fu, ask someone to bring a bucket of rubber over! Oh, and by the way, bring a big pot of white vinegar~!"
Li Zexuan pointed to the large factory building next to him and said to Uncle Fu.
"okay!"
Although Uncle Fu was wondering why Li Zexuan was jealous, he still nodded in agreement and ordered the people below to follow suit.
………………………
After a while, all the items were ready, and Fu Bo also brought several old craftsmen from the workshop to watch.
"Song Xiaosi, Pang Feiji, pour this bucket of rubber into the stone trough!"
Li Zexuan pointed to the rectangular stone trough in front of him and gave instructions to Song Xiaosi and Pang Feiji behind him.
This stone trough was originally used to anneal the blacksmith's iron when forging, but due to urgency, Li Zexuan could not find any more suitable container for a while.
"Yes, Master~!"
Song Xiaosi responded, and hurriedly and Pang Feiji worked together to lift the large wooden barrel filled with rubber. The white rubber latex immediately poured down into the sink. This stuff looked so thin that it really looked like soy milk. Likewise, it's no wonder that Fu Bo couldn't figure out the use of this thing.
"Well, pour all the vinegar in this pot again!"
Li Zexuan weighed the pot of white vinegar next to him and then ordered.
In the refining of rubber latex, a very important process is curing. In modern rubber latex curing processes, the most commonly used curing agents are formic acid and acetic acid.
Since 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 making the hydration film thinner, when the isoelectric point of the protein is reached, the electromotive potential is zero, and there is another gap between the rubber particles. There is no repulsion, they gather together and solidify into blocks.
In the 21st century, most foreign countries use formic acid as the coagulant, while in China, acetic acid is mainly used as the coagulant. Depending on the specific acid selected, the properties of the resulting glue will be different. These knowledge points were all learned by Li Zexuan from the factory owned by his rich classmate in his previous life. Otherwise, how would he know these things?
In the Tang Dynasty, formic acid was certainly not available, but acetic acid was! Because the so-called acetic acid also has a very popular name, that is, acetic acid. Vinegar contains a lot of acetic acid! This is also thanks to the wisdom of our ancestors who were the first to invent vinegar, otherwise Li Zexuan would have to make vinegar now.
"Now you two, go and get two hoe handles, wash them with hot water, and then bring them over and stir them vigorously~!"
Li Zexuan quickly ordered.
Song Xiaosi and Pang Feiji obeyed the order and left. After a while, the two of them walked in carrying a smooth hoe handle. Under Li Zexuan's demonstration, they began to use the stick to dig into the stone trough. Mix.
"Hey, hey, master! It's solidified, it's solidified! It was just like soy milk, but now it's turned into tofu~!"
After stirring for about two quarters of an hour, Pangfeiji suddenly shouted in surprise.
"It's really turned into tofu, come and see~!"
Song Xiaosi was also very excited.
There was no need for him to say anything. Uncle Fu and several other craftsmen had already joined in. Since the rubber latex that was previously sizzling now looked like tofu, Fu Bo couldn't help but marveled:
"Hey~! It's really strange! Didn't you just pour a pot of vinegar into it? Why is all the rubber solidified?"
"Yes! This is so strange, it's like a magic trick! If you hadn't seen it with your own eyes, it would have been unbelievable!"
The other craftsmen were also shocked. Since they had never learned chemical reactions, they could only classify it as a magic trick.
