"Come, here!" At this moment, a car with gas cylinders drove over. This is an ordinary van. The rear door was turned up, revealing the gas cylinders behind, two sky blue. At least half of the colored gas cylinders were exposed, and the car's engine made a rumbling roar and came quickly toward this side.

In the development of the national economy, it is inseparable from the transportation industry. In the transportation industry, various vehicles perform their duties. High-horsepower heavy trucks are mainly used on long-distance transportation routes, while light vehicles are used. To carry out short-distance transportation, in the short-distance transportation, the van is one of the best. It can pull people and goods. It is definitely a good helper to get rich and run well.

The steel plate suspension at the back, coupled with the rear-wheel drive, gives it a strong carrying capacity. Regardless of the size of the car, it can even pull two tons of cargo when needed.

Qin watched the car driving over. The words Haihe Dafa in front of the car were quite dazzling. This type of vehicle was produced by his own Haihe Automobile Factory. It has a wide sales volume. The yellow shell is even more beautiful.

The car is coming!

Several people started working together, carrying the heavy helium cylinder and placing it in the cabin of the airship.

If it’s a hard-shelled airship, there will always be a big guy on it, which is quite inconvenient. But now it’s all soft. The airbag on the airship is deflated before it is inflated. This is the first time. During the test flight, it was stacked directly into the upper end of the cabin, so now it seems that the airship is just a device like a minibus.

Qin Guan enthusiastically watched them install the helium cylinder, and asked puzzledly, "Why didn't this prepare in advance?"

Prepare in advance? Hearing Qin Guan’s question, the person in charge’s face was embarrassed: “This is not because we did not advance, our helium airship test flight, we have been waiting for this helium, until today we have the opportunity to get it. So the test flight is scheduled for today."

"I only got it today, is this thing difficult?" Qin Guan asked.

Qin Guan is in charge of the big scene, all kinds of strategic weapons, and the contract is easily measured by 100 million yuan. Therefore, Qin Guan did not expect that this small helium gas would be difficult to manufacture?

"Yes, our domestic helium industry is very small. Now the main helium is imported." The person in charge said.

A small gas cylinder came across the ocean, which aroused Qin Guan's interest even more: "What's the matter? Does it require high technology? Can it be extracted from the air?"

The liquid nitrogen and liquid oxygen that Qin Guan knows are all extracted from the air. The air can be liquefied by pressurizing and cooling the air. Depending on the liquefaction temperature of different gases, it can be easily extracted. The liquid required in the rocket Oxygen, the oxygen needed in industry, is all done in this way.

As for helium, it is an inert gas and has very little content in the air. It is estimated that this method cannot be used?

"It is extracted from the air, and the efficiency is too low. If it is used in industry, it is extracted from natural gas." Of course, the person in charge knows a lot about this aspect. Now Qin Guan asked about it, he began to explain Up.

"At present, this low-temperature condensation method is commonly used internationally. Natural gas is used as the gas source. The hydrogen sulfide, carbon dioxide, moisture, and even mercury in the gas source are purified by chemical methods before entering the cryogenic device. After the second condensation, crude helium with a helium content of about 60% is obtained. In this crude helium, the main magazine contained is hydrogen. This gas needs to be further removed. After several purifications, the final purity exceeds Ninety-nine percent helium."

The method mentioned is indeed complicated enough. Qin Guan nodded seriously: "So, is the output of this kind of helium in our country very small?"

"There is a part of crude helium, high-purity helium, we all rely on imports." The person in charge said.

Qin nodded his head and looked at the gas cylinder, and he also knew how heavy the pressure on his shoulders was.

Industry is all-encompassing, and it is not easy for me to take every part of it into consideration. If I did not come here, I would not know that industrial production of helium would be a problem in China.

It seems that I have to push it.

After all, in addition to being used in airships, this helium gas can also be used in many places, even in the military.

For example, the seeker of infrared missiles is cooled with helium. Many metal materials are welded under the protection of helium. The oxygen and nitrogen gas inside the submarine is put in a certain amount of helium to neutralize it. If it is, it can effectively avoid nitrogen poisoning when the nitrogen exceeds the standard; the closed launch box of the strategic missile needs to be filled with helium to neutralize the oxygen, play the role of maintenance, fire and explosion....

The domestic helium industry is quite backward, so if it encounters special circumstances, it will be restricted.

"In the past, our helium demand will not be delayed. We can import a large amount of helium from Eagle Country at any time. However, since last year, Eagle Country has imposed sanctions on us in terms of helium exports, and they strictly guard against this helium. Gas is used in other areas, so our helium is imported from the bear country at a high price.” The person in charge continued.

It looks like the electronic technology of the Kimchi country, which looks very advanced, but when the island country cut off several of the raw materials, the production line of the Kimchi country immediately fell into a crisis of suspension. Although the country has a large land and abundant resources, it has a complete industry. , But there are still shortcomings. If this shortcoming is not made up, it is easy to get stuck in the throat of others.

No wonder they have been waiting for helium gas. Imported helium gas from foreign countries is very expensive and small in quantity. Given the priority of military use, few can be used in civilian projects like theirs.

It seems that enough helium refining plants should be quickly established in China! This matter will be arranged soon!

"Start inflating!" Just after the installation of the cylinder, the person in charge shouted loudly, and finally the most exciting time has come!

In the cylinder, helium seems to be very small. Now, helium is flowing through the pressure reducing valve into the airbag on the top. The airbag begins to expand and expand, and soon, there is an elongated The shape of a water drop!

The first bottle of helium has been poured in, and then the second bottle, the airbag of the airship is fully bulged, the rudder surface of the tail is also stretched, the ropes tied to the ground are also supported, the airship Ready to go!

"Loosen the rope!"

The cables were loosened slowly, and as the cables were loosened, the airship began to slowly float upwards, and it flew up!
