The rise of nanometers

May 8th.

Huang Xiuyuan and his party took the high-speed train to Quancheng, Shandong Province.

At the train station in Yangcheng, a group of people were dressed very uniquely, because on the 3rd of this month, two cases of influenza A were confirmed at Yangcheng International Airport, and they returned from Mexico.

Yesterday, three more cases were confirmed at the Shanghai International Airport, and the cases came from California, USA.

Domestic airports, train stations, and port gates have all stepped up prevention efforts and deployed a large number of epidemic prevention personnel.

Now people in the country are wearing masks.

But the protective equipment used by Huang Xiuyuan and his team is indeed very unique.

Snail Industries started small-scale mass production of a gas helmet, just like a space helmet, a week ago.

One-third of the round helmet is made of nearly transparent silicon nanocloth, and then is a silver-gray aluminum alloy coated shell. The helmet has two small fans built in, which are set on both sides of the hollow bracket inside the head.

It is equipped with two removable lithium batteries. The batteries are wrapped with aluminum alloy silicon nano-coating to ensure that they will not explode and hurt people. The batteries are set on the shoulders on both sides of the neck with a capacity of 14,000 mAh. They can be charged without solar energy. , which can ensure that two small fans run for 8 hours.

On the top of the helmet, a 16-square-centimeter solar panel is embedded, which can charge the battery in the sun.

Inside the helmet, the hollow bracket on the top of the head, as well as the back of the head and back of the neck, are filled with a soft back pillow design, which can be used as a pillow by the user.

Under the chin, there is a hidden soft pop-up straw designed. Press the external switch and the straw will pop out. The pop-up position of the straw is just a little in front of the mouth, so you can suck it directly.

On the outside of the helmet where the straw is connected, there is a soft straw with a length of 20 cm, which can be put into a water bottle to drink water.

Coupled with the sci-fi design appearance, if they didn't wear protective clothing, they would look more like astronauts.

Although the mortality rate of influenza A is not that high, Huang Xiuyuan does not want to take risks. He has changed part of the future, which means that many things may deviate from his memory.

This kind of gas helmet, which has a service life of several decades, is specially designed to deal with biological weapons and malignant microorganisms. It has no protective effect against chemical gases and the like.

In fact, neither meltblown cloth nor more advanced silicon nanocloth has any protective effect against chemical gases.

To prevent chemical gases from entering the human body, the usual solution is to use adsorbents, neutralizing reagents, etc. in the filter tank.

In the future, there will be a special full-blocking gas helmet, but it will require very advanced nano-processing technology to allow only oxygen, carbon dioxide, nitrogen, and water molecules to pass through.

At this stage, there is no way to achieve targeted screening.

If a gas helmet made of silicon nanocloth is mass-produced, the material cost is about 24 yuan, and the processing cost is about 5 yuan. Including equipment depreciation, the comprehensive manufacturing cost is 40 yuan per piece.

The additional intellectual property rights are difficult to estimate. The current price of intellectual property rights set by the Ministry of Scientific Research is 100 yuan each. For every one million units produced, the price of intellectual property rights drops by 1 yuan.

The minimum price standard for intellectual property rights is 20 yuan each. This is the minimum price that will only drop after 80 million gas helmets are produced.

In terms of internal procurement, Snail Industry only earns a hard-earned profit of 170 yuan per gas helmet; while the price of external sales is 300 yuan per helmet.

Compared with the few cents a meltblown cloth mask costs, the price of a gas helmet is indeed very high, but the service life of a gas helmet is calculated starting from thirty years.

Moreover, gas helmets have other advantages, such as no stuffiness or difficulty breathing, no sweltering heat in summer, no water mist in winter, better protective effect than melt-blown cloth masks, and can be used in work and life for a long time.

It can even block large particles of dust in the air, and can be used as a motorcycle helmet. With the strength of the silicon nano-coating, it is impossible for a large truck to crush the gas helmet. The hollow brackets and back pillows inside can effectively buffer the impact of the impact. Keep your head safe.

At present, Blue Age has ordered the first batch of 150,000 gas helmets to Snail Industry, which are specially used by sanitation workers, gas delivery personnel, recycling factory employees, and water company employees.

Similarly, the head office, Fengmin Agriculture, Suiren Materials, Time Information, Locust Ant Company, and Snail Industry itself all purchased a batch.

In Shanmei, where the current headquarters is located, some sanitation workers and delivery personnel have been assigned gas helmets.

The sun is scorching hot in the Lingnan region in May.

Sprinkler trucks sprinkle water on the hot road surface to cool down and reduce dust. Many sanitation workers wear gas helmets. At first, they were not used to it, but under the blowing of the small fan, they felt cooler.

After more than a year of work, Liu Jianshe performed very well in various assessments. Two months ago, he was promoted to the director of the Xiangzhou Street Sanitation Station in the city, specializing in managing the street's sanitation work.

At this time, he was in a key area of ​​the street and told several sanitation workers: "Xiaohai, the Xiayang Passenger Terminal that you are responsible for should pay more attention to disinfection. If the trash can is full, let the cleaning truck pass by in time. "

Team leader Yu Donghai nodded: "Don't worry, stationmaster, we will ensure disinfection and hygiene here."

Wearing gas helmets and uniform orange-red work clothes, one of them also carried a hand sprayer, making people or passengers coming in and out of the passenger terminal feel as if they were in a biological crisis.

Sanitation workers responsible for disinfection carried out comprehensive disinfection at the entrance and exit of the passenger terminal, trash cans and public toilets.

Chen Youbo, who returned to his hometown from Xiangjiang, smelled the slightly pungent smell of August 4th disinfectant and the very clean road surface as soon as he left the passenger terminal.

He hadn't been back for more than two years. Although the buildings and lanes had not changed much, he felt a vague difference.

"Look, Dad, there are astronauts?" The boy on the side exclaimed, pointing at a few sanitation workers.

Chen Youbo looked at the standard of the other party's work clothes. It said "Shanmei Environmental Sanitation" and there was a line of smaller fonts underneath, which he couldn't see clearly.

"Don't run around, they are street sweepers."

The young man scratched his head and asked in confusion: "Dad, don't lie to me. The street sweepers in Xiangjiang are not like this."

Chen Youbo, who didn't know how to explain it, suddenly had a straight face and took a taxi with his son to Yutai Mountain Park.

Looking at the streets along the way, they still look the same, but they appear to be extremely clean. There are also many sanitation workers wearing gas helmets, and a few other uniformed personnel also wearing such helmets.

Chen Youbo turned his head and asked the taxi driver: "Master, are the sanitation workers in the city always like this?"

"That's not true. I only wore it a few days ago. It seems to be to prevent swine flu. Their Suiren company has a lot of things to do." The driver complained.

Suiren Company? This name sounds familiar?

"Brother, are you from Xiangjiang or Southeast Asia?"

Chen Youbo nodded: "I just came back from Xiangjiang."

"Then it's normal that you don't know the changes in Shanmei..." The driver was very talkative and introduced the changes between last year and this year while driving.

Suddenly, Chen Youbo finally remembered where he had heard of Suiren Company. This company is not only the parent company of Snail non-stick pans, but the kitchenware store he opened has also purchased goods from Snail, and the quality is indeed top-notch.

I didn’t expect that it was done by my hometown company.

I haven’t been back for more than two years. So many things have happened in my hometown. Looking back on the confusion I felt when I returned, now I feel more and more that the mainland is developing rapidly.

As the taxi passed an intersection, Chen Youbo noticed that more people were wearing gas helmets on both sides of the road. The driver explained a few words.

It turns out that this area is the office area of ​​Time Information, a subsidiary of Suiren Company, and the various subsidiaries of Time Information. Most of the people wearing gas helmets are employees of Suiren Company.

The helmet issued by the company is more comfortable to wear than a mask, and it can also prevent dust, odor, and PM2.5. The only inconvenience is eating and listening on the phone.

Snail Industry has received relevant feedback and is making improvements to launch a second-generation gas helmet.

at the same time.

The high-speed train that Huang Xiuyuan and his party took also stopped in Quancheng, Shandong Province.
