Barbarian in Douluo

Chapter 161 Chapter 163 Electrolysis of Saturated Salt Water (Subscribe)
After the rubber is solidified by adding acid, it can be collected and washed with water by a steam engine. After being pressed and dried, it becomes a yellow standard raw rubber.

This kind of raw rubber is very elastic, and it is almost difficult to find such a substance in nature, but the yellow standard raw rubber has a big disadvantage. It will become soft and sticky when exposed to the sun, making it difficult to use. At this time, it needs to be vulcanized. Only by processing can it form tire-like wear-resistant, hard and elastic industrial products that are not easy to break, and have high heat resistance and tensile strength.

Add sulfur to the raw rubber, and then heat it, and you will witness a miracle. The liquid-like raw rubber slowly solidifies and turns black, and gradually takes shape in the mould, and it becomes the tire that Tang Sangang loves so much.

The modern tire industry will also add other substances to help shape and increase strength, while the requirements of the Tang San bar are not so high. First, a batch of samples are produced, and then they are slowly approaching modernization.

"Why did it stop at the second pool?" Dugu Yan asked looking at the glue pool in the factory,

Tang Sanbang shrugged his shoulders, it's not due to lack of acid, the chemical factory is waiting for you to take office, he talked about the process of making rubber, and Dugu Yan's eyes showed a different kind of brilliance.

"Interesting! After using various chemicals to treat rubber, this kind of change will finally occur! It's really amazing. Let's go back to Wuhun City to make hydrochloric acid immediately. Find a few lightning-type soul masters, and we should be able to follow the instructions. The book claims to make hydrochloric acid."

"Okay! There is no time to wait, let's go back immediately!"

Wuhun City Chemical Factory,

Tang Sangang specially asked Bibi Dong for several soul masters who could continuously release lightning soul skills, and then prepared materials, a carbon rod, an iron rod, saturated salt water, a U-shaped tube, a plastic bottle, the experimental Let the thunder-type soul master hold a carbon rod and an iron rod in each hand, and pass the current into the saturated salt water, and the two gases should be produced.

The first experiment was just a small experiment. After all, it was probably the first time for Tang Sanbar to use lightning to electrolyze saturated salt water. He remembered that the connected batteries in the book also had positive and negative poles. How do people distinguish between positive and negative poles.If it is not controlled well, a large amount of hydrogen explosion will be produced, and it will not cause too serious losses.

Block the two openings of the U-shaped tube with rubber stoppers, insert a carbon rod in the middle of the rubber stopper, and immerse it in saturated saline. There is a small opening on each side of the tube, which is where hydrogen and chlorine gas are released. Connect the small tube to a For plastic bottles, use the air exhaust method to collect the gas, and then there is the ignition experiment that everyone wants to see. If an open flame can appear, then this experiment is successful.

Pour a large amount of table salt into the water glass until it can't be dissolved after several times of stirring, then pour it into the U-shaped tube, insert the rubber stopper in Tang Sanbar, and hand the test device to the thunder-type soul master who came.

"Hold these two sticks, release the thunderbolt, let the thunderbolt connect the two sticks through your hands, you understand."

The young thunder soul master nodded excitedly. It was the first time he stood so close to Master Tang, and he was very excited for a while.

Then get too excited,

bang~
The U-shaped tube was pinched and fried... The table was sprinkled with saturated salt water, and glass scum was everywhere.

The thunder soul master said with a crying face: "I... I really didn't do it on purpose!"

It didn't matter to Tang Sangang, he patted him on the shoulder, "It's okay, don't feel pressure,"

Then he directly took out ten U-shaped tubes, which were very cheap, and he could exchange hundreds of millions of them in the system.Repeat the steps just now, the thunder soul master is much more stable this time, please pick it up, don't dare to use any more force.

"Let's release the martial soul and soul skills."

The thunder soul master nodded, blue soul power gushed out from the body, under the possession of the martial soul, the face became sharper, the eyes turned blue, and the skin on the body also became darker. Two soul rings rose up, yellow and yellow, all of which were century-old soul rings.

"Thunder eel possessed!"

Tang three bars: 囧

There really is such a martial spirit!

"What's your name?" Tang Sangang asked,
"My lord, my name is Guya." Guya was very excited, and the strength in his hands became stronger with this excitement,
"Be careful!" Tang Sangang hastily reminded,

bang~
The second U-tube also blew up. . .

Tang Sanbang was quite helpless, looking at the broken glass on the table and Guya's mournful face, he had no choice but to comfort him: "It's okay, Susha is safe!"

Dugu Bo and Dugu Yan smiled at the side, they didn't expect Young Master Tang to be so charismatic, while the other soul masters in the company were very envious, they also wanted to get the care of this titled Douluo lord.

"continue."

Handed the configured U-tube to Guya again, and Tang Sangang didn't say a word very wittily, Guya also sorted out his emotions, took a deep breath, the first soul ring lit up, and the first soul skill: Thunder Armor, activate!

Bursts of blue lightning leaped up from Guya's body, jumping around the body, making hissing sounds from time to time, and as more and more leaping lightning bolts gradually covered the whole body, forming a lightning armor.

Tang Sangang nodded secretly, this is a soul skill mainly for defense, but it can also be used for attack, it will have a miraculous effect on soul masters of the assault type who mainly focus on melee combat.

Guia's whole body was surging with electric current, and as the index finger and thumb holding the iron rod and carbon rod entered the saturated saline solution, the experiment finally started. Seeing this, Tang Sangang immediately put one end of the soft leather tube into the left side of the U-shaped tube The other end was put into the small tube of the iron rod, and the other end was put into an upturned bottle. After standing for a while, a lot of gas was collected.

Take out the soft leather tube, put the plastic bottle on the table, smell the gas inside, there is no smell.

Then use the exclusion method, first of all not chlorine, because chlorine has a strong pungent smell.

A trace of flame appeared on the fingertips, Tang Sangang brought the flame closer to the bottle mouth,

Suddenly there was a bang!
It wasn't that the U-shaped tube exploded, but the gas in the bottle flashed over, and the bottle jumped up happily. Tang Sangang clearly saw the flames spewing out from the mouth of the bottle, and it was definitely hydrogen gas inside!

Dugu Yan's eyes lit up, and he hurriedly asked, "This should be hydrogen gas, I remember that in elementary chemistry, it was said that hydrogen gas is easy to deflagrate."

Tang Sangang smiled at the corner of his mouth, and nodded slightly, "That's right, hydrogen is colorless, transparent, extremely flammable, lighter than air, and has other uses, our experiment was a success!"

"As long as hydrogen and chlorine are mixed and burned, they will be hydrochloric acid after being dissolved in water, and the rubber can be made in the next step!"

"So, now you need a way to produce hydrochloric acid on a large scale. It is not enough to produce hydrochloric acid with just this little experiment."

"Don't worry! Leave it to me!"

Dugu Yan was full of confidence, she was very excited when she saw the hydrogen detonate!That's chemistry!That's chemistry!It releases extremely high heat and energy in an instant, and has a strong destructive power. When she thinks of something mentioned in a chemistry book, she becomes even more excited!

"Master Tang! I have a question to ask you, can we make this trinitrotoluene?"
