Monster Factory

Zhang Zhizhi and the policemen, like college students who are ignorant of the group, stepped into the lab for the first time to see the professors doing the experiments.

Both nervous and anticipating, surrounded by this German Goldman atomic absorption spectrometer.

The mystery of the concrete wall has been solved, and the remaining safes, as long as the puzzles are broken, they can more accurately locate the criminal profession according to the way of committing crimes.

The analysis time is a bit long.

Because the sample preparation of the atomic absorption spectrometer is cumbersome, it is necessary to collect the test sample, vaporize the sample, and then project the radiation to observe the spectrum generated when the sample absorbs radiation.

This is a very high-tech inspection method. Under this kind of detection means, all the foreign matter in the hole that is ablated by the high temperature is invisible.

Give a simple example.

At the beginning, Ye Qing had eaten the altar chicken in Shanghai and used soil to check for heavy metal residues.

If it is tested by an atomic absorption spectrometer, don't say it is seriously exceeded. Even if this altar chicken, for a lifetime, has eaten a harmful heavy metal food, the spectrometer can also test it out.

After an hour, the test results came out.

The report is composed of elements in English and symbols, and the technicians deliberately translate them into Chinese. If the police are treasured, look at the elements of the inside and look at them.

Ferrous oxide, ferroferric oxide, aluminum oxide, nickel oxide, magnesium oxide, calcium mono aluminate, silica calcium carbonate...

From the test results, almost all the metal components on the safe have been burnt into another substance at high temperatures.

The test results also indicate these components, which account for the proportion of the sample, of which the proportion of iron is the most, accounting for 55%.

"Wait, the safe shouldn't be metal, why is there a non-metallic substance such as calcium aluminate, silica?"

A sharp-eyed policeman, Columbus found the New World to be as excited as he shouted: "These kinds of non-metallic substances are likely to be criminals, the key to destroying the safe."

“What chemical reaction method is used? I remember that these ingredients can be used as chemical additives.”

Several police officers in the trace material examination room immediately began to discuss the use of these non-metallic elements.

"Cough ~"

Ye Qing somewhat could not bear to interrupt the police's "significant discovery" and discussed with them.

“I think... these non-metallic substances are part of the inside of the safe and the foaming fire barrier material.”

"........."

From the small circle of the trace material examination room, the atmosphere of the discussion was overwhelming, and their hearts were cold and cool.

"Ye Qing, it seems that in the hole that is ablated by high temperature, is there any foreign elemental composition?" Zhang Zhiyi is also very confused. The metal is heated in the air and will produce an oxidation reaction.

Then a lot of "oxidation" words on the test report sounded very high. In fact, it is ordinary iron, aluminum, magnesium, nickel, and what became after burning.

Ye Qing did not answer this question, but continued to look at the test report.

Zhang Zhizhen said that the metal components in the report are all materials for making the outer casing of the safe, without any foreign substances.

Things seem to be unscientific.

There must be a medium for burning, which is ignited with matches. It is bound to detect residual elements such as phosphorus and sulfur. Ignition with a mixed flammable gas will inevitably leave a residual element of common alkane, olefin, acetylene gas, and the like.

This world belongs to science, without magic, and without comprehension.

It seems that it is not scientific, it must not find the true mystery.

The police have been completely paralyzed. They feel that their IQ is no longer worthy of arresting these mysterious criminals.

Some people looked at the floor, some stared blankly at the test report, and others leaned on the chair and sighed, all the frustration and loss that could not be concealed.

"It turned out to be."

Ye Qing suddenly showed a confident smile.

This sentence is more effective than a strong heart. The policemen hurriedly raised their heads and stared at Ye Qing without hesitation.

“There is no unusual composition, but the ratio of the original metal components is not correct.” Ye Qing pointed to several metal components on the test report, and the corner of the mouth was tilted by a curve: “Aluminum, magnesium, the ingredients are wrong.”

“The addition of aluminum to metal materials can increase the strength and corrosion resistance of metals. However, the aluminum in this report is too high.”

"The wear-resistant steel for safes is usually the KN60 model. It is also used from the metal composition of this safe. I remember that in this wear-resistant steel, the proportion of aluminum added is only 3%, and here is the test. Out of aluminum, it accounts for 15%."

“The addition of magnesium is lower, and it seems that even 1% is not there, but 5% is detected here.”

No, what alloys can I use to sum up the metal?

The gang of police officers admire, and can not help but doubt, how about aluminum and magnesium?

"Any kind of alloy formula is the best ratio that has been obtained through long-term practice. No factory will make this stupid mistake."

"Since the factory is not wrong, it means that the extra aluminum and magnesium are added to the thief."

"Adding aluminum and magnesium?" Chapter's Emei shackles: "What do people want to do?"

"Iron oxide should be added, but there are too many iron components in the outer casing of the safe. There is not much change in the test report."

"Is it iron?"

“A very wonderful idea.” Ye Qing said with amazement: “This group of people is definitely not as simple as industrial processing, but very proficient, and can be called an engineer.”

"Aluminothermic reaction, or aluminum heat."

“Use aluminum powder, iron oxide powder, mix together, and use magnesium powder as an ignition agent.”

“When the mixing ratio is right, it can generate more than three thousand degrees of high temperature after ignition. In industrial applications, this method can be used to melt refractory metals or metal welding.”

It was another unpopular technique that they learned, and the police listened to their heads a little bit.

But Ye said that this method is generally used to melt metal or weld. That should not be ablated, is this hole with bullet shots?

"High pressure injection."

Ye Qingying decided: "It is mixed with a very fine metal powder in a pressure vessel, which ignites as much as a metal jet of an armor-piercing projectile."

“The finer the metal powder, the more complete the combustion. Take the most common iron, the ordinary iron, burned for a lifetime with a lighter. But the nano-scale iron powder burns with a little fire. Iron powder can be bought online."

"For the industrial masters, burn through the safe casing and use a few small tools to open the internal mechanical lock structure."

"..."

My godmother, which engineer is this full of support, ran to be a thief?

Have this technology stealing jewelry, go to the United States as a spy, steal high-tech information.

After listening to Ye Qing’s science, the policemen’s tears will come out. They feel that these masters of industrialization are terrible.

in case……

What if you like the industrial talents of Ye Zong to do things that are illegal and chaotic?

This is a very desperate speculation, but the police present at the scene thought about it. Ye always took out the same thing casually and could get the price of a building in their main building.

Their hearts were relieved and comfortable.

Tens of millions of gold jewels are in his eyes, and it is estimated that there will be a lot of dispensable materials.

"This will be a big case that sensationalizes the internal police system." After a long time of sighing, Zhang Zhiyin sighed: "I can come up with such unheard-of crimes. I really have no confidence in catching them."

"Try it and check out the major universities and laboratories. Ordinary technicians don't have the ability in this area. If the ratio of aluminothermic is not good, it becomes a burning bomb and burns itself into a turkey."

Ye Qing also sighed: "With this technology, it is a pity that we don't come to our factory to work as a thief."
