A group of students saw Director Yang chopping on the chopping board like a butcher Zhang, and a few couldn't help laughing.

This scene is really funny. Who would have thought that a factory manager of a large factory could come up with such a way to test the characteristics of new materials!

At this moment, Director Yang couldn't help but jokingly, "Xiaoxiao, in the future, this chopping test is still necessary, and you will come at that time!"

A group of students were silenced by Director Yang's joke. Although it was very inconsistent to appear in Wuchen Laboratory, they would not be vague if needed.

Chop rubber for the rise of flower planting!

As Director Yang lifted his knife and fell, after a moment, the rubber produced by Shanghu Rubber Factory had been cut into small strips. Although some parts were still connected, the position of the knife was indeed like a spider silk web, which was obviously unusable!

On the other hand, the performance of the new rubber is much ideal. Except for a few white marks on the surface, the rest are intact and the strength is still there.

After finishing the chopping test, Director Yang stood up and asked the students: "How is it? How should the results of this chopping experiment stay on paper? As I said! The new rubber is completely rolled on Shanghai rubber!"

"In the future, ordinary people will not ask about the parameters or pay attention to the data when they get our products. They only know that our rubber products are good! They are more durable than other companies!"

Upon hearing this, the students said seriously: "Director Yang, we remember that when collecting parameters in the future, we will also add practical tests!"

At this time, He Ku laughed and said, "Practical testing alone is not enough! We need to conduct various extreme tests for what we use ourselves. Don't be afraid of consuming materials, and don't be afraid of burning money! The products of the new factory are to be used with confidence and buy with peace of mind!"

"We need to conduct a fire resistance test when taking the welding gun!"

As soon as these words were spoken, everyone present was stunned...

Rubber is a combustible substance. Is it really good to conduct fire resistance testing?

Director Yang felt something was wrong and seemed to have thought of something, but he was just guessing and not sure.

After all, even if you can think about it, it is impossible to violate physical common sense and turn combustible materials into flame retardant materials!

But since we have to try, we must try it. The next moment, looking at the people standing there, Director Yang added: "What are you doing when you are still standing there?!! Go and prepare for the experimental environment. Extreme testing is still necessary. If you don't try, we will never know what we have developed!"

After saying that, Director Yang turned around suspiciously and asked, "Little Ku, don't hide it. Does the new rubber have fire resistance? I'll give me a surprise, right?"

As soon as this was said, the student who went to prepare the welding gun shook his head gently, "Impossible, Impossible."

How can natural rubber be flame retardant?

That is absolutely impossible!

He Ku smiled slightly without answering. Director Yang understood He Ku's confident expression in seconds, and he also looked forward to it in a mysterious way!

In his impression, He Ku is not a person who makes unreliable requests casually. When everyone knows that rubber is a combustible substance, if certain results are not achieved, this test will be meaningless. He Ku will definitely not make such a request!

Soon, the welding gun was ready, and He Ku immediately took it over and prepared for operation.

Under the gaze of everyone, a burning match struck through the jet pipe of the welding gun. The yellow flame tongue suddenly ignited from the tip of the gun. After slightly preheating, the flame tongue became extremely hot, and the temperature increased rapidly to the naked eye.

This is the well-known hydrogen-oxygen welding in later generations. It uses hydrogen-oxygen as fuel. The product after combustion of this gas is water, which is pollution-free, non-toxic, odorless and smoke-free. It can bring workers a refreshing working environment and will not inhale a large amount of toxic and harmful gases. It is a real green gas.

Moreover, it can also cut steel plates on small and medium-sized equipment, which is very convenient.

It is worth mentioning that this welding method should not have appeared at this time, and it was all due to the blockade of Germany.

When the new factory was built, the main body of the steel structure frame needed to be used for welding, and the welders knew about argon arc welding.

However, a can of argon gas, Deutsch dared to sell for 2,500 yuan, and the tungsten electrode was also charged randomly, which was extremely expensive. He really couldn't stand it. He made supporting equipment for hydrogen and oxygen welding in one day, breaking the blockade, and it has begun to become popular under the promotion of the new factory. Of course, the argon gas and tungsten electrode manufacturing technology of argon arc welding have also made breakthroughs!

Soon, the welding torch on He Kushou changed, the most obvious thing was the yellow flame tongue just now. The ultra-high temperature flame turned the original yellow flame tongue into a blue flame tongue. The temperature at this time was about 2,500 degrees.

At this moment, the onlookers had a judgment in their minds! Not to mention rubber, this temperature is enough to melt some common steel.

Under the gaze of everyone, the first one to appear was the rubber products from Shanghu Rubber Factory.

Before the high-temperature flames approached, this rubber began to spontaneously ignite, with open flames appearing, and the combustion is very fierce, and a stream of black smoke instantly emerged.

Even though he moved the welding gun away, the whole piece of rubber burned in a very short time and turned into a pile of black slag.

Faced with this result, everyone was not surprised at all, and this was the expected result.

Then there is the new type of rubber. When the high-temperature flame is approaching, it does not start to burn, but shows a little trace of melting, but this trace only stays on the surface and does not completely melt.

As the flame continues to approach the surface of the new rubber, the new rubber begins to change, and the burning position begins to deform, but there is no open flame, but it directly becomes a gray-black hard shell under the scorching flame.

Move the hydrogen-oxygen welding gun apart. Except for the location where the flame has been burned, it has been deformed and hardened, other locations are only slightly affected by the flame. The good flame resistance of the new rubber has been confirmed!

Seeing this situation, the expressions on everyone's faces were very complicated.

Some were surprised, some were incredible, and some felt like seeing ghosts.

Under the welding torch of more than 2,000 degrees, no one will question the fire resistance of the new rubber, which is visible to the naked eye and reliable, Niu Pi!

Everyone present, including Director Yang and many students, were shocked! A product that violated the physical properties of natural rubber was quietly released!

Director Yang looked at He Ku excitedly and gave a thumbs up, "Xiao Ku, is this material prepared for aircraft and rockets! Rubber fireproofing is unheard of, it is really amazing!"

He Ku smiled angrily and said, "You really dare to say that this material is specially prepared for insulated cables, not aircraft and rockets! The quality of the conventional cables used in our factory is worrying, and the probability of fire accidents is very high. As a leading unit in the metallurgy industry, we have the responsibility and obligation to invest a certain amount of energy in safe production and lead the healthy and steady development of the entire industry!"

The moment when He Ku finished speaking, not only Director Yang, but also many students expressed their doubts.

"General Manager He, is this still rubber? Look, the location where the welding gun just burned has hardened, like a protective shell!"

"Yes, it's obvious that this protective shell will also be protected by secondary protection!"

"It's really incredible that the new type of rubber can not only retardant, but also block flames!"

After looking at your words, the students who said I said, He Ku shook his head gently and explained: "The new type of rubber is a rubber product, but different auxiliary materials are added, which leads to the performance of ordinary rubber and flame retardant rubber, and will not make the cost unimaginable."

"Everyone has just seen it, and the conclusions I came to are quite similar to the original intention of my design. The new rubber at room temperature has the characteristics of ordinary rubber. Under the burning of high-temperature flames, a hard shell will be formed, continuing to protect the burned objects from damage."

"In addition, this layer of hard ceramic-like substance that is burnt and transformed is also a good isolation layer. Moreover, the longer the flame ablation time, the higher the temperature, the more obvious the hardness effect and the stronger the protection effect."

"I see!"

Many people suddenly realized that they were just hiking into the dead end of physical properties, and did not think that physical properties could also be changed through chemical means.

The simplest thing is to incorporate different materials.

Seeing that everyone was enlightened, he said, "There are still a lot of medium rubber today. You can test it slowly! Let's not accompany them for now! There is a kind of rubber that produces military boots. Please pay attention and test it first!"

"Okay! Mr. He, you won't be late?"

The students nodded one after another, and some even wanted to keep them and ask more questions.

He Ku shook his head and said, "No, if you have anything to think about, you have the ability to think independently and study independently, and then you can't understand it. Come to me on Monday!"

"Well, that's the case, I'll go to the production task now and make every effort to produce new cables. Remember to report this material." Director Yang also said, and together with He Ku, he left the laboratory.

I briefly talked to Director Yang about the types and quantity of rubber products this time. After the two parted, why both of them came to the location of the Hongqi car?

The training has been completed, and he and Nie Xiaoya can also have a good rest!

I don't know how long I have saved for the holiday.

"Here, here!"

Downstairs of the office building, Nie Xiaoya was waiting for Heku with a smile on her face. When she saw Heku for the first time, she hurriedly shouted twice.

"Let's go! The matter is finally half done! What do you want to eat at night?"

Why bother to breathe a sigh of relief? As long as you take the students well, the rubber factory in Bashu can be controlled remotely, so there is no need to go there.

Nie Xiaoya looked a little excited today, and her originally bright eyes narrowed into crescent moons, "Go and have snacks! We'll be on holiday tomorrow!"

Nodded, why open the Hongqi car door, and waited for Nie Xiaoya to get on the car and drove straight to the gate.

Now, it’s time to get off work, and many people have to come in and out, and the traffic at the gate is very high.

Therefore, He Ku drove very slowly and said hello to the employees around him from time to time.

When I arrived at the doorman, why did I find that the old man in the doorman was not on duty today, and it was replaced by Xu Damao.

Along the way, He Ku saw Xu Damao, one or two of them in a condescending manner, commanding workers to get off work cards. Some people knew what was going on, so they had to call Xu Damao several times before they could give in.

However, seeing He Ku, Xu Damao immediately nodded and bowed to He Ku, and from time to time he told the passing employees to go out quickly and not to block He Ku's vision, so as not to avoid his attentiveness being seen by He Ku.

When he arrived at the check-in position of the guard, He Ku took his and Nie Xiaoya's cards, took photos of himself, nodded to Xu Damao, and drove straight out in the car.

After receiving He Ku's nod, Xu Damao felt that he had gained He Ku's recognition. Xu Damao, who was originally smiling, became even more energetic.

At the same time, many employees were surprised to see that the doorman today was replaced by Xu Damao.

Although it is just a doorman position, those who can sit here in this era are all very experienced people.

Only with the qualifications can you suppress all kinds of monsters and monsters in the factory, and at the same time, you can better deal with emergencies that may occur at any time.

"Isn't that Xu Damao? Why is he qualified to be a guard!"

Obviously, Xu Damao was obviously not qualified to be a gatekeeper in everyone's mind. When he saw Xu Damao's gatekeeper, he didn't know who mentioned it, and everyone started to talk.

"Yes! I don't know how he came to the doorman. I remember his qualifications are completely unqualified!"

"Tsk tsk, you don't know yet. Last time a little thief came to our factory, which was the first one that Xu Damao discovered. I heard that he had captured the thief and made merits for the factory. Naturally, the security department should give me some preferential treatment. If you have merits, you must not be rewarded."

"I'm afraid it wasn't for the septic tank to drown that one? That night I watched Xu Damao chase a child, but this happened in the factory the next day. Did you think Xu Damao threw the little thief down?"

"Don't talk nonsense. Xu Damao was at most anxious. He didn't regard the life of the little flying thief as his life. As for throwing it down, he wouldn't dare to borrow some courage!"

"So that's it. Xu Damao is not a good thing! How can the security department in the factory let him see the gate? How can he be worthy of seeing the gate? He is just an indirect murderer!"

"We don't know whether to kill or not. I offended him last time. When I entered the door this morning, this guy asked me to swipe the card seven or eight times before letting me in. I heard that other buddies are treated similarly. You said, isn't this a villain successful?"

"What can I do? They are the doorman!"

......

When the workers passing by saw this scene, they all spoke sarcastic about Xu Damao.

As a former projectionist in the factory, Xu Damao is still very recognizable.

When the movie was first played, he could always make his leader "take a seat" for his leader without knowing what he wanted and leave the best position for him.

And these seats were stolen by Xu Damao from the butt of the employee!

Once a leader doesn't say hello, Xu Damao will give up his seat if he doesn't like anyone else. For so many years, everyone has complained about him, but due to his identity as a projectionist, he has never been guilty of him.

Just like Sha Zhu, Sha Zhu is in charge of food, and Xu Damao is in charge of entertainment, which are all popular.
