Chapter 150： trade

In addition, the standard hydrogen electrode uses platinum electrodes, also because of the high corrosion resistance of platinum.

In the laboratory, platinum wire can be used as an electrode. Thermogravimetric analysis will use platinum disks and holders, because it must be strictly chemically inert at high temperatures. Platinum is an alloy additive for various metal appliances, such as metal filaments, anti-corrosion experimental containers, medical equipment, dentures, electrical contacts, and thermocouples.

Platinum-cobalt alloy and iron-platinum alloy can be made into powerful permanent magnets. It is also the main material of the recording layer in the hard disk. Platinum-containing anodes are used in ships, pipelines, and steel terminals.

In short, platinum is a very valuable metal, and it is also on the exchange order presented by Ankai.

But this is a plan that Philip had never imagined.

Because in his vision, there must be precious metals, but there will also be a lot of ordinary metals like steel. Although Ankai has tried its best to keep prices down, because steel is easy to obtain, as long as Master is not stupid, he will inevitably exchange steel for part of the food. So the current situation, a little beyond Philip's expectations, made him feel at a loss for a moment.

But he reacted in the next moment.

The transaction cannot be stopped.

First of all, he can't let the other party think that they are holding their handles. This is very dangerous. In fact, although the shelter can now be equipped with iron ingots and it is not difficult to process it into steel, it is a good thing if there are external supplements because of the huge amount of subway construction. But on the other hand, even if there is no external supplement, it is nothing more than spending more time on their own, and it is not unacceptable. If these people really think that their shelters lack iron, although this does not actually affect the development of the shelters, it will affect the psychological level of both parties.

Now Ankai is occupying a high position, because Master and the others are even more short of food, which is directly related to the safety of so many people in the shelter. For Ankai's party, these materials are not necessary. It is good to have it, but it is not a big deal. This is a psychological game. In this case, An Kai and the others will be more calm, and to a certain extent, they can put forward more demands and overwhelm the other side.

On the other hand, even if there is no actual change, if the other party thinks that they can use Ankai's side, the psychological changes will inevitably suffer a change in behavior. From the beginning, he was cautious and trembling, becoming self-righteous and arrogant, and the respect for An Kai and the others would gradually disappear, and even in turn intended to influence An Kai and others. Of course An Kai can’t agree, but if it’s such a day, their refusal may cause dissatisfaction with the other party, which in turn will cause even bigger problems...

Therefore, the psychological game must never be lost.

Secondly, there is a saying that it is really difficult to mine metals like platinum from nature. It is not mining itself, but because the content of platinum in the earth's crust is not high enough, only when relatively rich mineral veins are found can there be mining value. Unless Ankai and the others have platinum mines at their feet, it is not that difficult to find them a little bit. It would be troublesome to find it in the city. If platinum and even other rare metals can be provided here, why not trade?

There is no such reason.

"good."

It's complicated to say. In fact, these thoughts only turned around in Philip's brain. It took only two or three seconds before Philip made a decision quickly.

His words made the people on the other side obviously relieved.

Then he took out a list with the exchange standard of distance written on it.

If it is platinum, every 500 grams can be exchanged for five times the weight of grain, that is, one catty of platinum can be exchanged for five catties of grain. To be honest, this exchange standard is almost like grabbing. In peaceful times, one gram of platinum costs hundreds of dollars. If it is used to sell grain, one pound of platinum can buy a cart of grain. But it was a peaceful age, and the food production was huge, enough to feed everyone. It's different now.

Doomsday, 99.99999...% of the survivors don’t need platinum. Except for some meaningless decorations, you can’t eat or drink this thing, and it’s meaningless to keep it too much.

Food is different. If you eat more food, you may live an extra day, maybe you can get new food and continue to live.

The status of both parties reversed instantly.

Ankai didn't have a big open mouth to exchange one catty of grain for five catties of platinum, which already gave these survivors a lot of face.

There are 1,700 catties of grain on the car, and if all platinum is exchanged, it can be exchanged for a full 340 catties of platinum.

If this was in peacetime, so much platinum, worth tens of millions, would be enough to buy food for a train.

However, now I can only exchange food for a small flat car. This business is really worth it!

The person on the other side never thought that the platinum in his hand was so worthless. Their box, which looked very heavy, was actually more than one hundred catties, less than one hundred and fifty catties, even half a cart of food. Can't change it back.

"This, is it a bit too expensive..."

The man in charge of communication asked tentatively.

"It's very expensive."

Philip nodded and admitted frankly, "But you don’t need to change it. We can change the food to anyone. We can change it to you. We also change it to others. Oh, I forgot to tell you. At that time, we met other survivors, who also expressed their willingness to do business with us, so...if you don’t want it, I can terminate this transaction."

Philip said in a calm and confident manner.

He really has nothing to fear.

The big deal is death.

Unless these people don’t want to live, how can they do it?

"Then, do you have gold?"

The man hesitated for a moment and asked.

"Yes, as long as there is on the list, we will have them. If not, we can wait for the next time when we come back to formulate new standards, or trade according to the biggest difference."

The biggest difference is that iron is exchanged for food. One catty of iron is exchanged for one catty of grain. If this ratio is used, Kent can't take the iron that was exchanged for this cart of grain.

is so exaggerated.

"this……"

The exchange ratio of gold is stronger than that of platinum. One catty of gold can be exchanged for eight catties of grain, which is slightly more expensive than platinum. The main reason is that in addition to being used as an ornament, gold itself has an unusually high value in industrial production. Gold is used in many precision instruments and aerospace fields. In addition, the electronics industry and modern communications industry are also inseparable from gold.

And hasn't gold always been more expensive than platinum? Ankai’s values ​​have always been simple.

So he is willing to give gold a higher value, if these people are willing to change, they don't mind.

The man on the opposite side was choked so much that he couldn't speak. After a long time, he waved his hand.

"Take out what we prepared."

He finally subdued.

This is the right thing. Since you are asking for something, don’t put on airs and trade obediently. Hello, I’m hello, everyone, isn’t it good?

Philip's mouth curled up, showing a faint smile.
