After leaving the back hall, he happened to meet Uncle Fu. Li Zexuan briefly told him about the newly established Funny Culture Department and asked him to cooperate with Ma Zhou's work in the future. He also repeatedly told him to improve Ma Zhou's salary and make sure that he He can work safely in the workshop.
After the explanation, Uncle Fu gave Li Zexuan two things, one was a horseshoe, and the other was a blood transfusion needle that Li Zexuan asked him to make a long time ago.
"Master, this is the horseshoe and needle you asked me to make before. Making this horseshoe is quite easy, just follow the drawings. I tried my best to make this needle and needle like this. "
Uncle Fu handed the thing to Li Zexuan and said with a wry smile.
Li Zexuan took it and took a look, and his forehead was suddenly filled with black lines. The needle was about as thick as a matchstick. Was it meant to stab someone to death? If it were any thicker, it would almost catch up with human blood vessels!
There was nothing to complain about the needle. There was no rubber these days. Li Zexuan thought for a long time before suggesting that Uncle Fu wash the animal's intestines, disinfect them with alcohol, rinse them with distilled water, and then attach them to the needle instead. Needle.
His previous equipment could not only be used to concentrate wine, but of course it could also be used to make distilled water. Li Zexuan also understood that the production process of this set of blood transfusion equipment was very troublesome. After all, every step had very strict requirements for the operator and no sources of contamination could be introduced. Therefore, he had never urged Fu Bo for so long.
But now this needle really makes him a little dissatisfied.
"Uncle Fu, can't this needle be made thinner? Is it as thick as an embroidery needle?"
Li Zexuan asked reluctantly.
Uncle Fu smiled bitterly and said: "Master, this is the thinnest needle tube we can make. Don't look at the embroidery needle that can be made very thin. It is drawn with an iron rod and then slowly polished. This needle of yours is... We made the iron pipe thinner and then polished it, but it can only be this thin at most. If it is any thinner, we are afraid it will break in the middle!"
Things can't be done, and Li Zexuan doesn't want to force Uncle Fu anymore. After all, the industrial foundation is too weak. There are not many professional machinery and equipment workshops. They all rely on pure hand polishing. It's not bad to be able to do this. It hurts a little. Well, I believe Qin Shubao can still bear this pain.
"That's alright, thank you for your hard work, Uncle Fu."
Li Zexuan waved his hand, took the horseshoe and needle, and went home.
… … …
After returning home, Li Zexuan went straight to the study to prepare a complete set of papermaking equipment.
The current papermaking technology of the Tang Dynasty is still inherited from the papermaking technology improved by Cai Lun during the Yuanxingyuan period of the Eastern Han Dynasty. At that time, he used bark, hemp heads, rags, fish nets and other raw materials, and after beating, pounding, copying, drying and other processes, he made paper. Compared with the paper made from plant fibers before the Eastern Han Dynasty, the cost of this kind of paper was indeed cheaper. It cost a lot, but since the papermaking process is completely manual, the cost is still very high, and it is not affordable for ordinary people.
It is recorded in the relevant history books of the Tang Dynasty that Huai Su practiced calligraphy with a wooden board and became a master of cursive script. When Bai Juyi was a child, he wrote stroke by stroke and did not dare to be careless, because a piece of paper was enough for several days. It can be seen that the price of paper in the Tang Dynasty was still very high.
Li Zexuan planned to draw a set of long mesh paper making machines. After the British brothers Fordlinier purchased the patent rights from the proposer of the paper machine principle, they handed it over to Tang Jin to improve the design and successfully produced the first one in 1803. A Fourdrinier paper machine capable of making paper, also known as a Fordrinier paper machine.
Its main feature is that it has a conveyor-belt-like forming section made of endless mesh. It consists of a wet section (including headbox, former, and press section) and a dry section (drying, calendering, and coiling).
At that time, the power source of this papermaking equipment relied on Watt's improved steam engine. However, based on the industrial foundation of the Tang Dynasty, there were still many difficulties in building a steam engine. So Li Zexuan made some changes and added some additions to the transmission and beating parts. The linkage structure allows this part to be replaced by animal power. Compared with the current traditional papermaking workshop, the paper output speed and papermaking efficiency are greatly improved, and the cost is also lower.
For other people, it would take two or three days to draw such a complex set of equipment drawings, but Li Zexuan is different. He has extraordinary mental strength and proficient control over power, and he can draw the drawings. It flows smoothly without any pause, just like a printing machine.
Nearly two hours later, Li Zexuan finally straightened up, shook his sore wrist, took a long breath, looked at the pile of drawings in front of him, smiled with satisfaction, and then called Sanbao and asked him to send it to the workshop and hand it over. To Forbes.
"Master, you told no one to disturb your drawing, but you have been drawing until now and haven't eaten at noon. I'll ask the kitchen to cook for you again."
Xiao Xi ran over and said with a distressed look on her face.
Li Zexuan then looked at the sky and saw that it was already past lunch time. Then he remembered that when he came back, he seemed to have told Xiao Xi not to be disturbed by anyone while he was painting. Who would have thought that he had been painting this painting until now and even forgot about lunch? After eating, my stomach made two "gurgling" sounds in protest.
Alas, I am not qualified as a rich second generation. How can there be a hungry rich second generation? Li Zexuan cursed in his heart, looked at Xiao Xi's pretty face, and said:
"Well, Xiao Xi, go quickly, go quickly, young master, I'm so hungry!"
Xiao Xi took the order and left. Li Zexuan admired the little girl's pretty back and couldn't help but sigh: It's so good to have such a little girl by my side. She can stretch out her hands with clothes and open her mouth with food. The key is that she is still pretty and has nothing to do. It’s eye-catching to look at!
Unknowingly, Li Zexuan went further and further down the path of decadence and decadence in feudal society, without looking back at all.
… …
After lunch in a hurry, Li Zexuan was just about to lie down and rest when Lan'er ran over.
"Brother, brother, Lan'er's little Huihui is being bullied by the big white horse. Go over and save it."
Li Zexuan was speechless. A dog could be bullied by a horse. What a mess.
"Xiao He, what's going on? Isn't the white horse at home recuperating recently?"
After the big white horse was injured that day and was brought back, Wang Zhong took the initiative to invite the best veterinarian in the city to treat its injury. Li Zexuan was surprised when he heard about this later. He didn't expect that There were actually specialized veterinarians in the Tang Dynasty.
Li Zexuan looked at Xiao He behind Lan'er and asked.
Xiao He looked at Lan'er and hesitated for a long time before whispering to Li Zexuan: "Master, the big white horse's injury was not serious before, but it has recovered today. Xiao Huihui still tried to tease it as before, but the result was... . ”
... ... ... ... ... ... .
Let's explode tomorrow. Let's explode that one. It'll make your forehead drip and your fingers scream!
Ahem, as you wish, this handicapped gangster is once again ready to explode for a few days, are you happy? Please subscribe and support!
Oops, I have a headache on my forehead and fingers. How can I treat it
Let me explain, regarding veterinarians, there were actually specialized veterinarians as early as the Spring and Autumn Period and the Warring States Period. I am not making this up, so don’t blame me for this.
