There is a type of paper that neitherIgnite by fire.

Left paper cloth, right A4 paper

And it won't be95% concentrationSulfuric acid corrosion.

Just use it togetherBoil the caustic soda solutionThe strength of this' paper 'is still considerable.

It is precisely this thin piece of paper,You can handle ChineseLifelineAnd make billions of dollars from it,And what is the secret behind this?

In fact, this magical 'paper' is not real paper, it is different from ordinary paper,But one of the world's three high-performance materials, calledAramid.

.

At the same time, aramid can also reduce the weight of the aircraft itself. It should be noted that,In the field of aerospace, for every kilogram of weight lost, it can be reduced1 million US dollars.

5621/5A42.7.

.

But such a key technology was a difficult problem for China to break through at that time,.

The reason for this is that China has always been studying this technologyCaught in the neck by the United States and JapanTherefore, for a long time,.

7090%.

Due to its monopoly position, DuPont not only raised the price when importing aramid paper in China, but also,202800.

.

Every year,China needs to spend up toRMB 19.5 billion.

.

But due to policy reasons,The ones they export to our country are still the outdated generation of aramid paper.

Aramid paper, a material with high toughness, high hardness, and lightweight properties, has long been the best choice for building rockets, but due to the monopoly of its core technology by the United States and Japan,.

.

.

So, in order to change this situation, China decided to independently research the manufacturing technology of aramid paper,.

.

But in order to elevate the country to a higher level in advanced technology.

In 2017, Zhang Meiyun led the team to achieve this achievementSecond Prize of the National Science and Technology Progress Award.

In just one year, it received an investment of 500 million yuan, and its annual output value reached 1 billion yuan,.

However, since we have taken the most difficult step, we believe that with the continuous development of science, we will definitely achieve the localization replacement of aramid paper in the future!
