(); Arriving at the designated place, Fa San immediately rushed over and whispered, "Sir, it's broken!"

Chang Ming glanced around him, there was no one else but him, obviously he was coming behind Wang Hai's back.

Chang Ming asked, "You calm down, what's wrong?"

Fa San said: "Why are you only here now, I have been waiting for you for a long time! After you left yesterday, the man surnamed Wang took me to the black market until it closed this morning, trapping me to death......" Speaking of this, he couldn't help but yawn again, and then became nervous again, "We searched all the wooden materials and special materials, and finally found the kind of shrub I said!"

As he spoke, he took out a small box, looked around vigilantly, handed it to Chang Ming and said, "This is the one I said!"

Chang Ming took it and asked, "Isn't it a good thing to find it?"

Fa San said: "I pointed out this thing to the kid according to what you said, according to expectations, this thing is not a finished product, the kid should ask me how to make it, but he didn't say anything, just patted me on the shoulder, took the thing and left!"

Fa San complained: "I was in a hurry, and I was afraid of revealing the stuffing, so I didn't dare to stop him, so I watched him go." Tsk, I should have stopped him for a moment, right?"

Chang Ming opened the box and took out the contents of it.

Different from the imaginary rubber, the box is a cloud of gray rubber, which is indeed a bit elastic, but the quality is very loose, and you can pull it off with a gentle pull, which feels like plasticine.

Seeing this situation, Chang Ming smiled and said, "It's okay, you're not a mechanic, that guy must think that with his own instinct, he can make it out, so he doesn't need you." ”

Fa San hurriedly said: "What should we do then? If he can get it out, then won't we have all kinds of ideas for the future?"

Chang Ming narrowed his eyes and said, "It's okay, if he can really find a way, then it's okay to give him this material." ”

Didn't you say that the price of this material is far more than a thousand gold coins, and it is simply a golden rooster that makes money!"

Chang Ming laughed: "So, aren't you a mechanic...... You see, if you can find this material on the black market, it proves that someone else has found it. Why hasn't a material been discovered being applied?"

Fa San was stunned, he really didn't think about it.

Chang Ming took the ball of cement and looked at it carefully: "The processing method of the raw materials is far more valuable than the raw materials themselves. If Wang Hai can find a way to deal with it and apply it himself, with his ability, it will be enough for you to earn a thousand gold coins!"

Fa San was a little frustrated: "In this way, my news is not worth anything at all......"

Chang Ming shook his head and said, "No, to be honest, there are no substitutes for this material, why haven't they been popularized and used? If this shrub really grows from Jintan City to the Minling Mountains as you said......

Fa San nodded vigorously and said, "Yes, that's it, I looked familiar when I was a child!"

Chang Ming said: "Then it is indeed very valuable for research!"

Chang Ming carefully took the cement back into the box and said to Fa San: "You wait a little longer, you keep in Wang Hai's field of vision." If Wang Hai can't study it, our plan can still continue as it is!"

Fa San nodded vigorously.

After Fa San left, Chang Ming looked at the time and decided not to go to the black market for the time being, and then study this material in the advanced agency room.

No one knows better what role rubber will play in modern industry. Being able to obtain a patent for rubber is no less important than the alloy formula I got last night!

One hour for others is eight hours for him.

After the virtual metal training room, Chang Ming reopened the virtual special material training room.

In modern industry, the first step in processing rubber is plasticizing, that is, using a strong external force to cut off the large molecules of rubber and make it easier to process.

A purity ban in the temple of the mechanism prohibits the existence of large machines, and it becomes impossible to use the power of machinery to mold the original gum.

After Chang Ming extracted the sample, he thought for a moment and decided to change his mind and use other methods to process it!

Chang Ming once spent a long time practicing the handling of special materials, and summed up a set of ideas from the middle.

The materials of this world are ever-changing and diverse, but they can be broadly grouped into several categories, each of which can be treated in a similar way.

For example, when he first arrived in this world, the people of Jinzhu Village needed to quench the impurities in the broken gold wires when dealing with broken gold wires. So they used a kind of saltpeter to grind the broken gold wire.

In fact, this is a chemical reaction, a certain ingredient in the saltpeter reacts with a specific impurity in the broken gold wire, resulting in neutralization, so that the impurities in the broken gold wire disappear.

This chemical reaction is a way of dealing with materials. Adding a substance to a material causes it, or other substances in it, to react with it and produce a change.

Other materials can be processed in one or more ways, and the results may or may not be the same.

Chang Ming still tried the plastic refining method first. Sure enough, the clump of cement was similar to the texture of rubber, and after repeated hammering, it gradually hardened. This is that its macromolecules have been cut off, and the original bullet surname has been greatly reduced.

This method does work, but it takes a lot of time. Chang Ming asked Ash to use a robotic arm to assist in his work, Ash is an artificial intelligence, the percussion action is stable and even, and the power is very balanced. Even then, it took a full two hours to get the job done.

This will definitely not work, and in this way, the processing time will be stretched too long, and it will lose its advantage in storage capacity. No matter how much the amount of raw glue is, you can only process so much glue at a time, can you maintain the production and let it be used in large quantities?

Chang Ming had already estimated this result, and of course he wouldn't expect too much on it.

When Xiaozhi was assisting in his work, Chang Ming made a variety of attempts on the cement. He used almost all the treatments applied to special materials to the copied cement.

In the end, he made a discovery!

When he chopped up the gum and added a powder added to it called "warm mud", the gum quickly changed and hardened into a hard solid!

This mass of solid can easily be beaten into a finely crushed powder that melts into a liquid when heated to a certain temperature. At this time, adding some substances to the liquid can make the colloids react differently, and after solidification, they have a variety of different surnames!

For example, adding 10% purple dust will make the colloidal hard and soft and not easy to wear, and adding 15% gray star sand will withstand high temperatures within 5000 degrees Celsius......

Chang Ming tried different additives repeatedly, and the results obtained were also different. This feeling is somewhat similar to blending alloys, not all formulas can be used, but different castes can have different effects.

Even if it's a scrap, maybe it's not a filler?

Finally, he finally got a complete set of methods for rubber that could be used as tires.

In fact, there is more than one formula for this, but the additives are not common enough, so Chang Ming finally chose a mixed additive. This hybrid additive is made from a mixture of two different substances, both of which are very common. After mixing them in proportion, and then interacting with the original rubber, you can get the finished rubber!

Chang Ming breathed a sigh of relief and felt a little sore in his neck.

It's been a long time since I've felt like this......

He straightened up, rubbed his neck, and turned his head to look at the time casually—

At this sight, he was shocked!

Now the outside time is 11 o'clock in the evening, and he has been in the office room for ten hours before he knows it, and the time in the office room has passed for another 80 hours!

But also, people have discovered a new formula in the laboratory, and it is all calculated on an annual basis. He's been lucky by the hour. This is also thanks to this virtual training room and Ash's help. Ash is a perfect assistant who has the same heart as him, and the virtual training room can directly present the synthesis results, so there is no need to spend more time practicing, which greatly saves his time!

Chang Ming picked up the formula of the tire and let out a long sigh of relief.

With this stuff, a lot of ideas can be put into practice!

He closed the room, and as soon as he opened the door, a man slammed in.

Chang Ming was stunned for a moment and asked, "Fasan, why are you here?"

Fa San jumped up and shouted, "Huh, you've been in the room all the time, why can't you knock so much, have you fallen asleep?"

Chang Ming avoided answering, and instead asked, "Why are you here?"

I sent three to look for him before, but I left a message downstairs to avoid people's eyes as much as possible. It's the first time I've come to the door like this, but I haven't found anyone waiting at the door!

Fa San immediately laughed: "Sir, you guessed right, I waited for the afternoon, and that guy really came to me! He told me that this kind of material can't be used at all, and he really doesn't know what to do with it!"

Chang Ming also smiled: "And then?"

Fa San said: "I'll sell him a little bit of the treatment you told me before!"

Chang Ming asked, "A little?"

Fa San laughed hehe: "Of course! This kind of good thing, how can you do it a few more times? I will break down the steps you said and sell them to him step by step! Do you know how much money I make now?"

He gestured two fingers: "20,000 gold coins! This is just the beginning!"

He said how he led Wang Hai to hand over the money step by step, Wang Hai is very stingy, how he tested his bottom line little by little, how to break through his defense little by little, let him take out the money little by little, and he didn't notice it at all!

He is indeed extremely talented in this regard, and every step is just right, accurately grasping Wang Hai's psychology, and letting a petty ghost take the initiative to pay for it! In this regard, he can indeed be called a self-taught psychological master!

Chang Ming listened for a while and asked, "He is the head snake of the earth, you are new to the city, are you not afraid of what he will do to you?"

Fa San smiled slyly: "Don't worry, I have a number." I'm a gangster, he's a dignified mechanic, he's a trickster, hehe!"

His face was full of pride, and Chang Ming glanced at him and smiled meaningfully. (To be continued.) )
