"Boss, since you said this kind of cigarette paper is very high-end, what raw material should be used? When our paper mill produces newsprint, most of it uses a variety of long-fiber grass and cheap wood." Look. When Shixiong agreed, Aidean looked very excited and began to ask questions.

"David, the requirements for cigarette paper are relatively high, thin, tough, and white, so you can’t use some grass as the raw material for making newsprint. Well, the best raw material for making cigarette paper is wood. Of course, also You can add a small amount of flax." Shixiong said.

　　 In later generations, there are many raw materials that can be used to make paper. Of course, the best of them is still wood, but there are too few trees in later generations, and people are not enough to plant trees. How can it be possible to use wood to make paper?

　　Only some very high-grade paper will use specially planted fast-growing poplar, fast-growing eucalyptus and other fast-growing tree species as raw materials. Most of the paper types are made from various grasses and a small amount of wood.

　　 However, there are too many miscellaneous cells that need to be raised when grass is used as a raw material for papermaking, so it is very difficult to treat the waste water produced by its papermaking. Moreover, the storage and transportation of grasses are inferior to that of wood, especially grasses are very easy to cause mildew and fire during storage.

　　Why did the following countries put so much effort in renovating small paper mills? It's very simple, because most of these small paper mills use grasses as raw materials for papermaking, which causes too much pollution. But the cost of wastewater treatment is very high. If the scale of the plant is not large, the wastewater treatment will greatly increase the cost.

　　 And if the scale of the factory is large, the cost of wastewater treatment will become much lower. This is why the large-scale paper mills are also using grasses as raw materials for papermaking, but the benefits can still be justified.

　　The cost of making paper with wood is high, but the pollution is low. The cost of making paper with grass is low, but the pollution is high. This is a contradiction that is difficult to resolve.

At this time, no one cares about the problem of pollution. The most important thing is that most of the area around the Gaoshu tribe and even east of the Mississippi River is covered with a lot of forest. How can the forest coverage rate catch up with later generations? The Amazon rainforest is gone, so there is no shortage of wood at this time.

　　 "Boss, what kind of wood is used? Presumably the wood used for this cigarette paper should also be very high-end, right?"

Shixiong shook his head and said: "The manufacturing process of cigarette paper and ordinary paper is actually the same, and the raw materials used are no different. It is just that some additives that are not used in ordinary paper need to be added in the process of making cigarette paper. It is like. The materials used for the cigarette paper we are going to make can be hardwood and softwood. The specific ratio is about 6:4, which means 60% hardwood and 40% softwood."

　　 These ratios are all learned by Shi Xiong from the Internet in his previous life.

　　 Just like in the paper industry, softwoods are called softwoods and hardwoods are called hardwoods. Paper made of softwood has good tensile strength, wet running performance, paper machine running performance, tearing and internal bonding strength; while paper made of hardwood has good bulk, stiffness and opacity And has excellent performance in dimensional stability.

　　 As high-grade paper, cigarette paper must combine the advantages of two paper-making raw materials.

Hearing Shixiong's words, Aidean stuck his tongue out, "My head, this paper-making material is high-grade enough. If all of our paper mills use this material to make paper, our paper mill might have closed down long ago. "

Shi Xiong smiled and said, "Your home is yours, and your paper mill is in the Old Continent. Have you seen so many trees in the Old Continent?" Shi Xiong pointed around, "Here, some There are inexhaustible trees, you can use whatever you want. Well, there are a lot of pine trees above the mountainside of the Great Smoky Mountains, whether they are longleaf pine or loblolly pine, they are excellent raw materials for papermaking. And below the mountainside, You can use all those oak trees, and this oak tree is excellent for making paper."

David Adion looked around in the direction of Shixiong's fingers, and shook his head again with constipation, "Boss, this is too extravagant, so extravagant, so extravagant that I am embarrassed to start... ..."

　　 The two laughed loudly.

After 　　 laughed, Shixiong went on to say: "In addition to these raw materials, a lot of additives need to be added in the papermaking process. For example, calcium carbonate."

　　 "Calcium carbonate?" Aidean was a little confused.

　　 Ishikuma realized that there was no such thing as calcium carbonate at this time, and at this time, the European paper industry did not seem to use calcium carbonate in the papermaking process, so he said: "It's limestone or marble."

　　 "Oh..." Edian just understood.

"This kind of additive is an important additive in cigarette paper. Well, it is a bit unsuitable to say that the additive is actually a bit unsuitable. It is more accurate to call it the raw material. Because in the process of making cigarette paper, nearly one-third of the raw materials are made of this Kind of limestone or marble. But this thing must be of good quality, and it must be crushed into powder."

"Boss, this is easy to say, as long as I know what it is, I can get it out. Our tribe has a large stone mill. I heard Jack said that he is going to make a large steel mill to grind some hardness. Larger things. As long as Jack makes a steel mill, the calcium carbonate powder you are talking about is absolutely fine."

　　 "Yeah." Shixiong nodded with satisfaction, "In addition to calcium carbonate, you also need to prepare some starch. This thing is both a strengthening agent and a retention aid, and it is a very critical additive."

　　 "Starch? It's the kind of thing extracted from potatoes, right?"

　　 "Yes, that's the kind of white powdery object, that's starch."

"I know how to extract this. I have extracted it before. After crushing the potatoes, soak them in clean water~lightnovelpub.net~ to filter out the residue and add a lot of water to let it stand for more than ten minutes. Pour out the clear water on the bottom. The thing that settles is starch. I have done this before."

　　 "Okay, you know how to extract starch. There are so many potatoes in our tribe, you can refine more. In fact, this stuff is also very good for cooking."

　　 "God! Can you make delicious meals with this thing? Is it just like the delicious meals you made before?"

　　 Shixiong glanced at the foodie, nodded with a smile, and Aidean waved his fist in excitement.

　　 "David, in the process of making cigarette paper, you need to add a kind of combustion-supporting agent. We have this kind of combustion-supporting agent here. You can ask Ferguson for it, which is the purified nitrate."

　　 When making cigarette paper for later generations, it is necessary to add a combustion aid, which will cause an exothermic reaction when the cigarette paper is burned, which is consistent with the burning speed of tobacco. Most later cigarette papers used potassium citrate, sodium citrate or potassium tartrate or sodium tartrate as combustion enhancers. Of course, there were also potassium nitrate, i.e., sodium nitrate or sodium nitrate, as combustion enhancers.

　　 The former Shi Xiong can't come out for the time being, but what he has here is that using this thing as a combustion-supporting agent is no problem.

　　 As for the defoamers and preservatives in the cigarette paper, Shixiong didn't plan to add them, and he couldn't figure it out. But as long as there are the most important additives, even if the cigarette paper made is not as good as the cigarette paper of later generations, it is enough to make cigarettes. And the cigarettes made are guaranteed to be absolutely high-end during this period.
