Dashu and Luo Chong looked at each other after hearing what Xiaohe said, then smiled silently, and then listened to Dashu's introduction.
"This is the leader of our Han tribe. If your leader wants to talk about something, just let him come over. Also, let him bring that red rice. We don't like 'empty talk'. As for what you want to do, for the sake of red rice, as long as it is not particularly difficult, we will seriously consider it."
Xiaohe was shocked when he heard this. It turned out that the young man who had just talked to him for a long time was the leader of the Han tribe. A person's reputation is like a tree's shadow. The name of leader Luo Chong is still very deterrent. This is not because Luo Chong himself looks so terrible, but the terrible size of the Han tribe. A tribe with advanced technology and a large population, such a tribal leader, his words can decide the life and death of some people. It is not an exaggeration to say that his words are followed by laws.
After learning the identity of the person in front of him, Xiao He also put away his carefree attitude just now, and respectfully clasped his hands together again, and bowed deeply to Luo Chong.
At the same time, he suddenly remembered that he felt that this person looked familiar just now. He was familiar. There was no coin of the Han tribe that did not see this person's head portrait. It was just that the dress was a little different. If he changed into a crown and a flat crown, and was a little older, he would definitely be recognized at a glance.
"Hello, Han Shou leader, I will tell our leader about these things when I go back, and ask him to bring the red rice to meet you in person tomorrow."
"Well, that's it, you can go to the market." Luo Chong simply replied and sent this nervous guy away.
Xiao He also, after learning Luo Chong's identity, did not dare to breathe, bowed to Luo Chong again, and then turned around and left quickly.
As for Luo Chong, after learning that the Ling tribe did have sorghum rice, he was relieved. He and Dashu looked at the green rice fields by the river for a while, and then went to the market in the city to eat a bowl of white porridge and pickles to solve the problem of breakfast. Then the two continued to inspect Liuyang County.
The three counties of the Han tribe all have their own special industries. The textile and metallurgical industries in Hanyang County are the most developed. Although the sericulture in Ruyang County has just started, it has also entered a stable development period. Liuyang County is not bad either, and it has mastered all the papermaking workshops in the Han tribe.
Entering the newly built paper mill, it is early summer now. The papermaking shed is filled with smoke. Many men are shirtless and work with their trouser legs rolled up. Because of the problem of drying with the heated kang, the temperature here is too high. It is better in winter, but now it is summer, which is really unbearable.
Today, the roll paper production line has been expanded to 20. On each production line, there are seven or eight people busy. Some people are dedicated to providing pedal power, and some people are checking whether the flame in the drying bed is strong at any time. Some people are adding pulp and water to the storage tank in front, constantly adjusting the concentration of the pulp.
All the way from the pulp to the drying bed, and finally to the roll paper rack, the paper here is considered a finished product. At that time, just spread the paper and cut it into the corresponding size, and it can be used.
However, the papermaking industry in Liuyang County uses all the pulp from the pulp trees on the Nanshan Mountain. However, with the increase in production lines and output, the pulp trees on the mountain have gradually failed to supply raw materials. If production continues at this rate, it may not take long for the production to stop due to insufficient raw materials.
At present, all the paper in the Han tribe is basically supplied to government agencies. The amount consumed is really limited. Most of it is stored in inventory, and a large part of it is sent to various counties to paste windows.
But the workshop cannot stop production for this reason. Now that there is no ready-made raw material such as pulp trees, it is a good opportunity to try more on other trees and try the effects of other materials in papermaking. It can also be regarded as an experiment.
Luo Chong chose three kinds of materials this time, namely bamboo, waste residue of sweet stalks, and rice straw.
All three materials can be used to make paper pulp. I won’t talk about bamboo. There are many people who used bamboo to make paper in their previous life. The Lianshi paper made of bamboo was also very famous in ancient times. It can be used to print books for hundreds of years without rotting.
Luo Chong has only heard that waste residue of sweet stalks is used to make pulp and paper. In fact, he has no idea about the effect.
The last straw papermaking is easy to understand. Straw is yellow, and the paper made from it generally maintains its original color, so it is also called original color paper.
Like the yellow exercise books in childhood, the yellow paper used to wrap pills in clinics, the yellow paper used to pad sesame cakes in meat buns, the rhubarb paper used to wrap medicinal materials in Chinese medicine stores, and the paper used to wrap snacks in pastry shops, most of them use this kind of paper.
This kind of paper is of poor quality and is not very good for writing, but in this era without plastic bags, it is still a good material for wrapping paper.
In fact, Luo Chong had seen this stuff a lot when he was a child. At that time, in the small places in the village, people would send some cakes during festivals. They would wrap a square package with this yellow paper, stack several packages together, and stick a piece of red paper with auspicious words and advertisements on the top. Then they would tie them together with fine hemp ropes and carry them away. In that era, carrying a pile of cakes was the happiest thing for the elderly.
As for the specific method of making primary color paper, with the current papermaking technology, as long as the previous pulping link is done, the subsequent process can almost be completed on the assembly line.
In order to increase the speed of pulping, Luo Chong used the method of chopping the straw with a guillotine, then rinsing it with clean water several times, soaking it in water for a day, and after it was thoroughly moistened, put it in a large pot and boil it with alkaline water, and finally take it out to drain the water and steam it in a pot.
To put it bluntly, it is to use the dual means of physics and chemistry to destroy the straw desperately, so that the fibers in it can be decomposed and softened, and the time of natural reaction can be accelerated.
After steaming, it is put into a treadle to pound into qualified dry materials, and then diluted with water to become yellow pulp.
However, there is a pro and a con. After all this tossing, the straw decomposes and softens quickly, but the sewage generated in this process is a lot. Even modern papermaking cannot escape this pollution problem. It is conceivable how much pollution is emitted by papermaking.
This problem was not solved before because the pulp at that time came from pulp trees, pure natural raw materials, zero emissions, and zero pollution. Other bamboo papers need to be soaked for half a year. That is not very polluting, but it takes too much time.
Now, to make primary color paper, no matter what method is used, pollution emissions are inevitable. However, Luo Chong has another solution, which is to discharge the dirty water used to boil straw into the manure pit, so that the alkaline water and the uric acid in the manure pit are neutralized and turned into part of the fertilizer. You must know that straw can be directly put into the manure pit to be rotted into fertilizer. This treatment method is not harmful at all, on the contrary, it can promote the birth of fertilizer.
