Monster Factory

Zhang Zhizhi and the cops, like a bunch of knowledgeable college students, stepped into the lab for the first time to watch professors do experiments.

Nervous and expectant, surrounded by this German Goldman atomic absorption spectrometer.

The mysteries of the concrete walls have been unraveled, and the remaining safes, once solved, allow them to more accurately locate the criminal's profession according to the modus operandi.

This analysis was somewhat lengthy.

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

This is a very high-tech test, under which all foreign substances are invisible in the hole that is ablated by high temperatures.

Give a simple example.

When Ye Qing ate the jar chicken in Shanghai, the soil method detected that there was heavy metal residue inside.

If an atomic absorption spectrometer is used to test, let alone severely exceed the standard. Even this jar chicken, for the rest of his life, has eaten a bite of harmful heavy metal food, and the spectrometer can test it.

An hour later, the test results came out.

The report list is composed of elements represented by English and symbols, which the technician deliberately translated into Chinese. If the policemen are treasured, they look at the elements inside, one by one.

ferrous oxide, ferrous tetraoxide, aluminum trioxide, nickel oxide, magnesium oxide, monocalcium aluminate, calcium silicate…

From the test results, almost all the metal components on the safe were burned to another substance at high temperatures.

The test results also indicate these ingredients, which account for the largest proportion of iron in the sample, accounting for 55 per cent.

“Wait, shouldn't the safe be metallic, why are there non-metallic substances like calcium aluminate and silica in it? ”

Columbus, an eye-catching policeman, found the new continent shouting as excitedly: "These non-metallic substances, most likely criminals, are the key to sabotaging safe deposit boxes. ”

“What kind of chemical reactions are used? I remember all of these ingredients being used as chemical additives. ”

Several policemen from the trace evidence lab immediately began discussions on the use of these non-metallic components.

“cough cough ~”

Ye Qing somewhat impatiently interrupted the police officer's "major discovery” and had heated discussions with them.

“I think… these non-metallic materials are part of the internal, foam-proof compartment of the safe. ”

“ ……… ”

A small circle from the microphysical examination room, the atmosphere was awkward for a moment, and their hearts were cool.

“Ye Qing, doesn't it look like there are any foreign elements in the cave that are ablated at high temperatures?” The chapters are similarly confusing and the metal is heated in the air to produce an oxidative reaction.

So there's a lot of “oxidation” on the test report, and it sounds very tall, which is actually normal iron, aluminum, magnesium, nickel, something that burns to become.

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

Zhang Zhi is right, the metal composition in the report is one of the materials used to make the safe housing, and there are no foreign substances.

Things seemed to get unscientific all at once.

Combustion will inevitably have a medium, ignited with matches, and residual elements such as phosphorus and sulfur will inevitably be detected. Ignition with a mixture of flammable gases will inevitably also leave behind residual elements such as common alkane, alkene, acetylene, etc.

The world belongs to science, there is no magic, there is no cultivation.

Seems unscientific, must have missed the true mystery.

The policemen have completely lost their intelligence and are no longer worthy of capturing these mysterious criminals.

Some people look at the floor, others stare at the test reports, and others lean against the chair and sigh, all of them uncovered frustration and loss.

“So that's how it is. ”

Ye Qing suddenly revealed a bamboo smile on his chest.

This sentence is more effective than a compass. The policemen hurriedly raised their heads and stared at Ye Qing without hesitation. At the same time, they made an ear wash letter.

“There are no different ingredients, but the ratio of the original metallic ingredients is incorrect.” Ye Qing pointed to several metallic ingredients on the test report sheet, and the corners of his mouth raised an arc: “Aluminum, magnesium, the ingredients are incorrect. ”

“The addition of aluminum to metal materials improves the strength and corrosion resistance of metals. But the aluminum in this report is out of scale. ”

“Abrasion-resistant steel for safes is usually a KN60 model, which is also used in terms of the metal composition of this safe. I remember that in this abrasion-resistant steel, only 3% of the aluminum was added, while 15% of the aluminum was detected here. ”

“The magnesium addition rate is even lower, and seems to be less than 1%, but 5% was detected here. ”

No way. What kind of alloy can be summed up from a metal component?

The cops admire it and can't help wondering, what happens when there's too much aluminum and magnesium?

“Any alloy formula is an optimal matching value that has been explored over a long period of practice, and no factory will make this stupid mistake in mismatching. ”

“Since the factory can't go wrong, it means extra aluminum and magnesium, added by the thieves. ”

“Add aluminum and magnesium?” Zhang Zhiyu's Eyebrow Lock: “What do these people want? ”

“Iron oxide should also be added, except in the case of a safe with too much iron, which does not show much variation from the test reports. ”

“And iron? ”

“Very brilliant idea.” Ye Qing praised: “These people are definitely not as simple as industrial processing, but very knowledgeable, which is the rank of engineer. ”

“Aluminum thermal reaction, or aluminum thermal agent. ”

“Aluminum powder, iron oxide powder, mixed together, magnesium powder as a flame initiator. ”

“Properly mixed, high temperatures of more than 3,000 degrees can be produced after ignition, and in industrial applications this method is used to melt refractory metals, or metal welding. ”

Another cold door technique they learned, the police listened to the head a little bit.

Ye always said that this method is generally used to melt metals, or weld them. That's not gonna burn out, is it? This hole with the bullet?

“High Pressure Spray. ”

"Mixed in a pressure vessel with very fine metal powder, this ignition effect is no less than the metal jet of a crushed shell," Ye Qingdu said. ”

“The finer the metal powder, the more it burns. For the most common iron, ordinary iron, can't burn with a lighter forever. But nano-grade iron powder, it burns with a little fire. And nano-grade iron powder, available online. ”

“For these industrialists, burning through the safe-deposit enclosure and using a few gadgets at will can pry open the interior mechanical locking structure. ”

“ …… ”

Oh, my God, who the hell is this engineer who's hungry and runs off to be a thief?

What kind of jewelry does this technology steal, spy on America, steal high-tech materials?

After listening to Ye Qing's Cop, the policemen were about to burst into tears. They thought these industrial-savvy canadas were too scary.

If…

What would happen if an industrial talent like President Ye did something illegal and irregular?

This is a very hopeless speculation, but the policemen present, thinking about President Ye can come up with one thing at the price of one of their headquarters buildings.

They were relieved and comfortable.

In his eyes, tens of millions of gold and jewelry are probably just a pile of materials.

“This is going to be a big case of sensationalising the internal system of the national police.” For a long time, Zhang sighed: “I have no confidence in catching them with this unprecedented modus operandi. ”

“Try it and check out the universities and laboratories. Ordinary technicians who do not have the ability to do so. An aluminum heat agent is not a good match, so it becomes an incendiary bomb and burns itself into a turkey. ”

Ye Qing sighed as well: “With this technology, it would be a shame not to come to our factory to work and be a thief. ”
