Chapter 63: Technology Innovation

Charcoal was placed in the room, and Chen Wanrong grabbed Zheng Qing and said, "I'll do it."

Zheng Qing thought she was not a master, and half of her master was considered a master, so she said, "Brother Chen, are you just treating others as an outsider?"

This is to feel sorry for her, not to treat her as an outsider, this is another saying of "I am half a master". Chen Wanrong knew that what girls need most at this time is not to give pain, but to give recognition, and smiled and said, "Then let's carry it."

It hurts people and recognizes her. This method is good. Zheng Qing is extremely happy and laughs a lot. She nods gently, stretches out her little hand like white jade, grabs a corner of the bag, and works with Chen Wanrong to carry out a bag of less than twenty kilograms of charcoal, and happiness is overflowing on her face.

Qing'e looked at the two of them and couldn't help but curl her lips and teased them. Chen Wanrong was a big man with a thick-skinned face and didn't care. He blinked at Qing'e and replied to her: "You have to be careful, be careful not to get married."

"People mouth." No matter how generous a woman is, she will be ashamed of her children. Qing'e's face turned red with shame and gave Chen Wanrong a blank look.

In Zheng Qing's mind, Qing'e was a sister. Seeing that she was embarrassed, she hurriedly begged for her: "Brother Chen, don't say such shameful words, okay?"

Wen Xiang said softly, but she couldn't refuse. Chen Wanrong nodded and said, "For the sake of your lady, I'll spare you this time. If you dare to talk nonsense again, you will be responsible for the consequences!" He had a tense face, and was joking, and he was like an ultimatum. His acting skills were really good.

Knowing that Chen Wanrong was joking, the woman was afraid of those shameful words, so Qing'e had to surrender and make a fortune in a quiet voice. She glanced at Chen Wanrong and stopped talking.

Put down the bag, grab some charcoal and throw it into the stove hole. Then find a brazier and clean it up a little. When the charcoal in the stove hole was burning, Chen Wanrong then grabbed it into the brazier with tongs. Then put charcoal into the brazier, piled it together, and fanned it with a fan.

This is the best charcoal, which is easy to catch fire. In just a short while, a pot of charcoal fire is burning very vigorously. Move three small stools and put them on the ground to form a shaped shape, which is quite suitable for the height.

Finally, move the circular porcelain plates and place them on three small stools, facing the brazier in the center. Then bring the zeolite, clean the soil on them, and put them on the porcelain plates to bake.

The charcoal fire was burning strongly. After a while, the zeolite expanded, and water vapor continued to emerge, making a hissing sound. Zheng Qing pointed at the zeolite and smiled: "Brother Chen, this stone is still the same. It will come out of water as soon as it is burned. It's so fun!" Look at her excited look, as if she was back to playing with burning zeolites when she was a child.

Qing'e's eyes had never seen Qing open her eyes and looked at the zeolite in surprise: "Where does the water come from? There is water in the stone?"

The zeolite itself does not contain moisture, but the crystal structure of the zeolite is in the shape of a frame and has many cavities. It is precisely because of this cavity that it absorbs water. The moisture absorbed by the zeolite will evaporate again as soon as it is heated. Now that the temperature rises, the water begins to evaporate, and the zeolite expands into foam.

Chen Wanrong looked at Qing'e's surprised look, smiled slightly, and then put zeolites on it until the porcelain plate was filled before stopping.

Dozens of zeolites of varying sizes were heated together, and the water evaporated. The hissing sound sounded like a piece, which was quite spectacular. Zheng Qing had burned zeolites before, but she had never burned so many zeolites. Her eyes couldn't help but widen. She looked at the zeolite in surprise, as if the zeolite was a magnet, and her eyes were attracted by iron blocks.

Qing'e was not much better, staring at the zeolite stupidly, not even knowing that the firewood in her hand had fallen out.

"Wanrong, what are you doing?" Chen Houshi rubbed his hands and came over quickly, his eyes staring like copper bells, staring at the zeolites that were bubbling.

Xiao Shangrong trotted over and asked, "Brother, are you doing something new?" He stopped suddenly, staring at the zeolite bubbled on the porcelain board, his eyes widened, and he was stunned for a moment, and then said, "Why is water growing inside the stone?"

Chen Wanrong looked around and saw many employees stretching their necks, their eyes wider than cows, and they looked curious, looking at this side. If it weren't for Chen Wanrong's presence, they would have rushed over to see the things. The employees saw Chen Wanrong looking at them and went back to work. Before Chen Wanrong's eyes could be swept to her, Han Huahua hid back in the house.

Looking at their amazing appearance, Chen Wanrong had to explain to them: "It's not that the stone has water, but that the zeolite absorbs water. The zeolite can also absorb water, just like the cloth absorbs water. The only difference is that when the cloth is wet, we can see it, while when the zeolite is stained with water, we can't see it."

The moisture in the zeolite exists in the cavity of the molecule, and no matter how good the vision is, it cannot be seen. A large piece of cloth will get wet when it is watered. As long as the eyes are not in trouble, you can see it without any surprise.

The explanation is simple and easy to understand. Chen Zhen nodded and said, "So that's how it is!" He looked confused and absolutely did not understand.

"Old man, what are you watching? You don't go back to work, come and join in the fun?" Chen Wang came over and wiped his hands and complained.

"Woman, come and see the stone grows water!" Chen Laoshi pointed at the zeolite and introduced it to Chen Wangshi very excitedly.

Chen Wangshi came over and looked at her with a surprised face, but she cleverly chose not to ask, but instead scolded Chen Zhen: "Old man, you are not young anymore, like a child, how fun is it? Go back and work quickly."

"I'll just watch it for a while, why are you so nagging?" Chen Laoshi was very dissatisfied.

Xiao Shangrong saw the signs and muttered a few words in Chen Laoshi's ear. Chen Laoshi suddenly realized, touched his face, and said, "Wanrong, you are busy, I'm going to work." Without waiting for Chen Wanrong to speak, he left quickly.

Chen Wangshi said, "Miss Zheng, don't be too tired!" and Xiao Shangrong hurriedly left.

Looking at the backs of the three of them, Zheng Qing burst out laughing and glanced at Chen Wanrong, feeling ashamed. Chen Wangshi knew very well, just not let Chen Laoshi and the others disturb Chen Wanrong in their major life events, so he sent Chen Laoshi away. Zheng Qing's heart was very clear.

"Miss, you guys do it first. I'll see what those sisters are busy with." Qing'e was also tactful and stood up and was about to leave.

Although the world of the two was warm, they were just facing Chen Wanrong alone. Zheng Qing was very willing, but she was a little timid and hurriedly grabbed Qing'e: "You burn the fire, you are not allowed to go anywhere!" She even put on the airs of a lady.

Qing'e stuck out her tongue, sat down as she said, and then threw away the firewood. Only then did Zheng Qing feel relieved and looked at the zeolite again.

Some of the bubbles on the zeolites are gone. Chen Wanrong knew that this is because the water contained in the zeolite has evaporated. He clamped the zeolite with his pliers and put it on another porcelain plate to cool. Put the zeolite on the edge on the charcoal fire, and then put the zeolite on the ground on the edge and roast it. The advantage of this is to save time.

The reason why the zeolite is cooled is that the temperature is too high, causing local overheating to cause large amounts of water vapor to evaporate and take away some sulfuric acid. Furthermore, the local temperature is too high, which will cause the solution to splash everywhere. If one is not good for splashing on people, it will cause accidents. This is considered from a safety perspective.

The zeolites were constantly cold, so Chen Wanrong put them into the sulfuric acid solution. He put more than a dozen pieces in a row, and then he fed a small basin of clean water and placed them next to him. After a while, it was estimated that the zeolite had been fully absorbed. Then he clamped the zeolite and shook it gently to let the solution above flow back into the basin as much as possible, and then put the zeolite in clean water to clean it.

The reason for cleaning is that there is a sulfuric acid solution on the zeolite. This way, part of it can be recovered. The next time you make sulfuric acid, you can use it as a dilute solution. You should know that sulfuric acid is very expensive now and you will lose as little as possible.

After cleaning, the zeolite was put back on the porcelain plate and baked. Zheng Qing looked at it in surprise for a while and took on the responsibility of maintaining the charcoal fire. She put charcoal into the brazier, so the fire in the brazier has always been very prosperous.

After just repeating it twice, Zheng Qing's careful observation was reflected and she asked in surprise: "Brother Chen, why are there so many missing?"

The water absorption of zeolites can be reused. When the zeolite absorbs enough water, the water will evaporate after heating. At this time, the zeolite has nothing in its cavity and can absorb water again. Chen Wanrong uses this feature to prepare concentrated sulfuric acid. Otherwise, under the current conditions, without industrial equipment, it is simply a fantasy to make concentrated sulfuric acid.

Chen Wanrong shook the zeolite on the pliers and explained: "Water absorbs the zeolite. The zeolite is like a cloth sheet, and can absorb water repeatedly. After the cloth sheet absorbs enough water, twist it with your hands, and you can absorb it again. The zeolite cannot be twisted with your hands, but you have to burn it with fire. After it is burned, you can absorb it again."

This explanation is simple and easy to understand. Zheng Qing Bingxue's smart man understood it as soon as he heard it, and praised him: "It's so magical!"

Qing'e's eyes were wide open, she looked at Chen Wanrong without saying anything, and there was a little more praise in her eyes.

After sucking a few more times, Zheng Qing was surprised to find that the water originally had good fluidity no longer flowed as freely as it had just now. The water concave formed by putting down the zeolite slowly returned to its original state, not instantly recovering as soon as it had just now. After hesitating for a moment, he asked, "Why does water become like oil?"

Sulfuric acid is an oil-based viscous and transparent liquid. Of course, this characteristic needs to be reflected, and a certain concentration is required. Dilute sulfuric acid is as fluid as water. Now that the concentration has increased, this characteristic of sulfuric acid has been revealed.

This problem is really not easy to explain. Chen Wanrong pondered for a moment and said, "Sulphuric acid is the same as oil and is not easy to flow. However, if sulfuric acid is poured into water, it is no different from water. The zeolite absorbs water almost all, so the sulfuric acid returns to its original appearance." This refers to fluidity.

Zheng Qing was extremely smart, and immediately thought of another aspect and asked excitedly: "Brother Chen, is it going to be done?"

Now this concentration is still far from 100% concentration, but it is almost close. It is not wrong to say that it is almost healed, so he must say, "Yes! Remember, don't touch it with your hands."

Sulfuric acid is very corrosive, and once it is touched on the skin, the consequences are unimaginable. Chen Wanrong gave a special reminder.

Although Zheng Qing didn't understand the reason, she believed that Chen Wanrong would never harm her. She gently said: "Brother Chen, I'll go find a cloth piece now." She was anxious to see the yellowing of the cloth piece, and was as anxious as a child who was eager to get a toy.

She couldn't understand the dehydration of sulfuric acid, but the cloth sheets that Chen Wanrong said would turn yellow when they encountered sulfuric acid, which impressed her. Now the conditions are about to mature, and she can't be anxious. People are curious, and this is the flesh and blood person.

"Okay!" Chen Wanrong would not refuse her request.

Zheng Qing responded happily, as happy as a cheerful bird, quickly entered the house. When she came out of the house, she held three pieces of cloth in her hand, gave Qing'e one piece and Chen Wanrong one piece, and held the last piece tightly in her hand, staring at the sulfuric acid anxiously, hoping to test it immediately.

Qing'e walked to Zheng Qing with a cloth piece, stood side by side, staring at the sulfuric acid, so anxious that she was even more anxious than Zheng Qing.

Chen Wanrong recited the physical and chemical properties of sulfuric acid, so he didn't have to do this experiment at all. However, Yiren had this intention, and Chen Wanrong could not help but put the cloth on her shoulders.

After absorbing it a few more times, Chen Wanrong looked at the zeolite. It was no longer as wet and dry as before. It was covered with viscous sulfuric acid instead of the rapid flowing water. He knew that the concentrated sulfuric acid was ready.

Chen Wanrong held the cloth in his hand and dragged it with the zeolite on it a few times. The cloth was covered with sulfuric acid, as if it was coated with transparent oil, and it was shining against the sunlight. He placed the cloth on the edge of the porcelain plate and pressed it with a zeolite.

"Be careful, don't touch your body." Before Chen Wanrong could speak, Zheng Qing handed over the cloth piece in her hand. Chen Wanrong reminded her to use zeolite to drag it over the cloth piece.

Zheng Qing carefully placed the cloth piece on the edge of the porcelain plate and pressed it with zeolite. The blue calyx was applied as the method.

The sulfuric acid has been made, and the next thing is to store it. Chen Wanrong put the zeolite in a basin to clean it and put it on a porcelain plate to bake.

"Brother Chen, look, look, the cloth has really turned yellow!" Zheng Qing screamed in surprise. She has always been persistent and calm. This is the first time Chen Wanrong has heard of her since she met her.

This cannot be blamed for her. In the eyes of the ancients, it turned yellow when it encountered sulfuric acid, and it lost its moisture like fallen leaves in autumn. It was beyond her understanding. It would not be astonished.

Not to mention Qing'e, her white little hands were covering her mouth desperately, her eyes wider than those of cow's eyes, and she kept beating gently. If she hadn't covered her mouth, she would have screamed: "Oh my god, it's so amazing!"

Chen Wanrong decided to let them see something even more magical. He poked the pliers in his hand towards the yellow spot and easily passed through the cloth piece. A piece of cloth piece slowly fell to the ground.

This is too difficult to understand. If it weren't for witnessing it with your own eyes, Zheng Qing wouldn't have believed that the pliers would have passed through the cloth so easily. This time, he was so shocked that he even forgot to speak, and only stared at the rags on the ground with his eyes wide open and stared at the rags on the ground.

Qing'e is not much better, as if a statue is stuck on the ground.

The cloth is still covered with sulfuric acid. If it is accidentally exposed to it, it will cause unnecessary damage. Chen Wanrong clamps the cloth with pliers and throws it into the stove hole to burn it.

It was not until this time that the two girls of Zheng Qing woke up. Zheng Qing looked at Chen Wanrong with joy and said softly: "Brother Chen, you are so awesome!"

Of course, Chen Wanrong is amazing. Without modern equipment, he used the most primitive method to prepare sulfuric acid at a concentration of nearly 100% in the history of science and technology. This is definitely a great feat!

With a slight smile, Chen Wanrong brought the container, wiped it clean with a cloth piece, poured the concentrated sulfuric acid into the porcelain. Tighten the lid, and then wiped the joint with yellow wax. The airtightness problem will be solved, so you don’t have to worry about the sulfuric acid absorbing water again.

This container is a porcelain custom made by Chen Wanrong from Yuan Tiancheng, which has good corrosion resistance. There are threads on the lid, which greatly improves the air tightness. If you apply yellow wax, there will be no moisture in any case. Fortunately, Chen Wanrong used threads to make a small improvement in the porcelain, otherwise even if concentrated sulfuric acid is made, there will be no things to store without a glass container.

Move it into the house and place it in the corner of the wall. Find a note, write the word "Don't move", and post it on the container. The concentrated sulfuric acid has been prepared. Although the amount is not large, only about ten kilograms, it is a good start and has great significance.

Zheng Qing was in high spirits and snuggled up to Chen Wanrong: "Brother Chen, can we do it again?"

Chen Wanrong could understand her mood, but the conditions are not ripe now, and explained: "I can't do it now. I have to wait until the concentration of sulfuric acid is higher before doing it, which will save a lot of trouble."

The concentration of sulfuric acid is too low now. If you use zeolites to absorb water, it will take a lot longer. It is better to wait until the concentration is higher. Although Zheng Qing was sorry, she still followed Chen Wanrong: "Brother Chen, I will listen to you."

After leaving the house, I looked at the zeolites on the porcelain plate. More than a dozen pieces were dried. If I just collected them like this, it would be too unprofitable. I just used these ready-made conditions to make ether. There are zeolites and concentrated sulfuric acid, making ether would be the most suitable.

Having a certain idea, Chen Wanrong was about to enter the house to move the wine, but Xiao Shangrong looked frightened and hurriedly ran in, panting and said, "Brother, something big happened, go and see!"

"I'm so nervous, keep calm!" Chen Wanrong's face sank, he scolded and asked, "What's the matter?"
