Some people say that tung oil is an important strategic material in war, why?

The importance of tung oil should start from its role. The processed tung oil has an important role in waterproof, anti-corrosion and rust prevention, and brushing a layer of tung oil on military equipment and equipment can make the equipment and equipment more durable and last longer. From guns to tanks and submarines, the cost of each item is particularly high, and if there is no tung oil "bodyguard", it is easy to rub and break, and the high cost is a waste.

Take skin care as an example, tung oil is like sunscreen, understand its significance!

It is widely distributed in the hilly areas of southern China, and it has medicinal and industrial value, and the industrial value is mentioned more. It has a high economic value as a dry oil. In addition to the above, the main advantages are non-conductive, cold and heat resistance, acid and alkali resistance, which is really a lot of advantages.

Tung oil has been used in ancient times in our country, Zheng He's treasure ships in the West are very famous in history, and these ships are coated with tung oil.

We know that firearms are very susceptible to wear and tear, and sweat can also cause damage to firearms in situations of high stress. But after brushing tung oil, these damage will be reduced a lot. The same goes for other military equipment.

The strategic significance of tung oil can also be seen from some historical events.

In the early days of the Anti-Japanese War, China's strategic materials were very scarce and needed to be imported from other countries. However, the United States, which was rich in supplies at the time, was unwilling to provide support to China. But we also want to get loans and supplies from the United States.

Chen Guangfu proposed to go to the United States for negotiations, and the condition of the negotiations was to exchange tung oil. The United States actually agreed, which shows that the strategic significance of the oil tung is huge.

With the progress of industry, there are now many materials that are gradually replacing tung oil, but the industrial value of tung oil still cannot be underestimated.

Tung oil is a particularly useful thing, as it prevents rust in iron products such as weapons, and prevents mold in wood.

I think tung oil is probably a lubricant that lubricates some of the instruments of war, what guns, in order to prevent them from reacting with moisture in the air. Therefore, a layer of copper oil has the function of anti-rust.

Tung oil can be used to protect machinery**, and also has a certain medical effect, which is an indispensable material in war.

Tung oil is used to prevent rust, of course it is very important in war, it is said to have a medical effect, anyway, its existence is definitely very beneficial to the war.

Tung oil has the function of rust prevention, wiping with tung oil can extend the service life, and tung oil was only available in China at that time, and we got a lot of it by selling tung oil.

Tung oil is actually protected in war, and most of it is made of iron when it rusts and ages. Children's oil protects against oxidation.

Tung oil can prevent weapons from rusting and aging due to marching and fighting, and can help soldiers protect weapons so that they can fight a more beautiful battle.

Tung oil plays an important role in warfare, and weapons are metal products, which need tung oil to lubricate and prevent rust.

The function of tung oil is to lubricate some weapons, such as guns or other **, and when fighting, guns are very important.

Guns also need to be maintained in war, and tung oil has the function of anti-rust and quick drying, which can be used to maintain guns.

Because tung oil can be used to protect machinery, it also has a certain medical effect, and is an indispensable material in war. Tung oil is an excellent vegetable oil with dryness, which has the characteristics of fast drying, light specific gravity, good gloss, strong adhesion, heat resistance, acid resistance, alkali resistance, anti-corrosion, anti-rust, non-conductive and other characteristics, and has a wide range of uses.

Tung oil. Tung oil is the main raw material for the manufacture of paints and inks, and is widely used as waterproof, anti-corrosion and anti-rust coatings for construction, machinery, weapons, vehicles and ships, fishing gear and electrical appliances, and can be used to make oilcloth, oiled paper, soap, pesticides and medical vomiting agents, insecticides, etc.

Yunnan Province is an important production area of tung oil in China, and its annual output now ranks sixth in the country. The production areas are distributed in Zhaotong, Wenshan, Qujing, Baoshan, Dali, Yuxi, Dehong and other places.

Tung oil is an industrial vegetable oil made by mechanically pressing, processing and refining jujubes, and the whole process is a physical method.

What is the role of tung oil, and why was it a strategic material before? Today is a long time to see.

Speaking of tung oil, in fact, there is quite a saying, because Xiao Yisou saw the original appearance of this thing when he was a child, it is actually a plane tree, but it doesn't seem to have any effect, and the fruit can't be eaten with good limbs, but the leaves are relatively large and more fun, so some netizens want to ask, this thing is actually very useful in the war Tung oil is a very important strategic material in the war, so why does the dragon add points to the magic bow skill of tung oil in this regard? Let's take a look at this problem!

Speaking of tung oil, we have to talk about the two monopoly products of China in World War II: tung oil and pig bristles. The bristles, that is, the bristles on the back of the pig, were a lever to measure the quality of the pig hair, since the native pigs in China at that time were free-range. Rent annihilation.

At that time, tung oil was monopolized. At that time, about 90% of the world's tung oil came from China, and China's tung oil was led by Sichuan. Because of its acid-resistant, quick-drying, flammable and other characteristics, tung oil is widely used in military applications, such as aircraft and submarines.

At that time, due to the lack of diesel and gasoline in the country, coupled with the blockade of the eastern seaboard, there was not much oil available. And our e-vision aggregation network film and television is just going straight and refining with tung oil, which can be regarded as an urgent need. Hitler's use of coal to refine oil had the same effect.

And because we were poor and weak at that time, we had nothing to sell, and even if it was possible, we were not competitive, so selling tung oil to foreign countries became a road. In addition, because we are rich in tung oil, we also used the economic loan of the "Tung Oil Loan Contract" for the first time in exchange for the aid of the U.S. military, breaking the neutrality of the United States.

So in World War II, tung oil was a strategic material for the United States and an important strategic material for our country.

As a natural refining and processing of industrial vegetable oil, tung oil has a wide range of uses. Tung oil has waterproofness, widely used in construction, printing, electronics industry, etc., and with the increasing development of China's economy, the demand for energy continues to increase, the choice of tung oil as an alternative bioenergy is also one of the choices in the future.

Tung oil plays an important role in our economic development today.

Use value. Tung oil is an industrial vegetable oil made by mechanical pressing and refining of the harvested tung tree fruits, and the whole process is a physical method. The paulownia tree is a perennial woody forest tree that grows in mountainous areas far from cities.

It is extremely resistant to diseases and insects, and does not need to apply fertilizers and pesticides during the whole growth process. Tung oil is a natural plant oil, which has the characteristics of rapid drying, high temperature resistance, and corrosion resistance. Tung oil also has good waterproofness, and is widely used in construction, paint, printing (ink), agricultural machinery, electronic industry or industry.

When it comes to important strategic materials in modern warfare, oil is definitely one of the most indispensable. But in fact, there is another kind of oil, which is also an indispensable and important strategic material, and it is tung oil.

When it comes to tung oil, many people may not know what it is. In fact, tung oil is the oil squeezed from the seeds of the tung tree fruit, which is an excellent dry vegetable oil, which is the main raw material for the manufacture of paints, coatings, inks, etc.

It sounds like it has a lot to do with strategic materials, and it's hard to imagine that it will be an important strategic material.

Of course, it's normal to have such thoughts. In fact, although China has been producing tung oil on a large scale since the Tang Dynasty, and has always been the world's largest producer of tung oil, but for a long time during this period, tung oil was mainly used in civilian life, rarely involved in the military field, let alone not strategic materials.

However, it was not until the outbreak of World War I and World War II that the value of tung oil was finally revealed, and there was a saying circulating in the army at that time: "A tung tree is worth a machine gun; A tung oil fruit is worth a grenade, and a tung boy is worth a bullet", which shows the importance of tung oil.

So, what exactly is tung oil used for? As you know, since the beginning of the Industrial Revolution, the world's machinery and equipment have replaced traditional tools, and a large number of steel manufacturing equipment has continued to appear, which has also led to the fact that in the war, various tanks, trains, airplanes, armored vehicles, artillery, machine guns and other steel fever have begun to be used in a large area.

But the problem is that these steel machinery and equipment were faced with a very serious problem at that time, that is, how to prevent water and rust. If this problem is not solved well, these devices will soon become unusable. Later, it was found that there is a large amount of tung oleic acid (C18H30O2) in tung oil, which can quickly react with oxygen in the air to form a dense paint film.

If lead monoxide is added to tung oil as an additive, the paint based on tung oil can even be dried in ten minutes. With this protective layer, machinery and equipment made of steel can be well protected from rust and water. So in the early 20th century, tung oil naturally became the "first" of all industrial equipment.

For our country, during the War of Resistance Against Japanese Aggression, we have an urgent need for automobiles, but we can't produce them domestically, and many places along the coast are still blocked by the Japanese army, so we used 220,000 tons of tung oil from the United States within five years as collateral to obtain a loan of 25 million US dollars from the Export-Import Bank of the United States to the Chinese company, thus obtaining a batch of urgently needed anti-Japanese war materials.

According to statistics, in the 14 years from 1922 to 1936, China's tung oil exports increased from 450,910 quintals to 867783 quintals, and in 1937, the export volume exceeded 1 million quintals, earning nearly 100 million tons of foreign exchange for the country, which was China's largest export commodity at that time, not only for China to exchange a large amount of money and grain, but also made great contributions to the victory of the Anti-Japanese War, so it is also called an important strategic material.

Tung oil is the basic material for the manufacture of first-class quick-drying paint, and only with quick-drying paint, the production and protection of the first can be tested, so tung oil has become an important strategic resource.

In modern warfare, there is a steel craze for tanks, airplanes, etc. Waterproof and rust prevention became the primary problem, and it was later found that the tung oleic acid of tung oil can quickly react with air to form a paint film. Therefore, people usually use tung oil to smear these hot ** to prevent water and rust.

Because tung oil has a good waterproof and rust prevention effect, I think it is really important for people who are fighting wars.
