The professor wants to continue to improve the life of the material, but the technical level of the British is not omnipotent, compared to the PMMA material, a backward aircraft light-transmitting material technology tree, Europe and the United States have long switched to the PC material route, the research on PMMA materials has been stopped for several years, and the relative republic is only a little more advanced in technology, but it will definitely not be too much.

John made it clear that there are too many inherent limitations in PMMA material technology, even after the use of anti-ultraviolet coating technology, it is already the current limit to be able to improve the life of the product, and if you want to improve the life expectancy, you can only start from the material itself, that is, the ability to resist high temperatures, and this is a dead end that European and American countries have made great efforts to walk.

Knowing that the biggest limit of the PMMA material route ends here, I don't think too much about it, the service life of two years is actually acceptable, and after getting the lightness brought by the material, I must pay some other price, and the service life is destined to be sacrificed.

This time I came to the optical laboratory to communicate, not only about the life of PMMA materials, in fact, John is more concerned about the exchange of PMMA material bulletproof technology, which involves whether he can get military goggles with excellent performance before returning to the UK, which is indeed related to his pocket.

"It seems that you have developed a suitable UV protection coating, which is really good news, it is a clear proof that you have a good level of technology, and I believe that the bulletproof technology that we are going to talk about will be much easier to communicate. ”

.......

Seeing that the British, who usually worked in the translucent factory, were so active when they arrived at the laboratory, not only analyzed the problems encountered in the laboratory from beginning to end, but also directly gave solutions to the problems.

Taking advantage of the fact that he didn't need to translate too much when he was doing the experiment, he couldn't wait to find Wang Zhengguo, and now he especially wanted to find out the reason for this, why the Englishman had such a big change in attitude before and after, and it was like breaking his glasses.

Looking at Wang Zhengguo again, I found that he was really hidden, and he definitely had a hand, and he immediately became a friend: "Let me introduce myself again, Jiang Zhongxian of the Foreign Affairs Department of the Ministry of Aviation Industry." I always thought that the British were all nostrils to the sky, but I didn't expect you to work so hard after being invited by Shuhang Optics, I can't believe it!"

In fact, the two of them can only be regarded as having some contact at work before, and it is the kind of nature that after one contact, there will never be a second time, naturally neither of them has the intention of befriending each other, but now it is different, when Jiang Zhongxian understands the situation, it is really admiration from the bottom of his heart.

After introducing himself more formally, Wang Zhengguo couldn't continue to do nothing at this time, and then introduced himself politely.

On the one hand, I also felt that this person was not bad before, and on the other hand, it was also considered that it was best not to offend this person, after all, it was a person from the Foreign Affairs Department of the Ministry, and it was not important to say how critical the position was, but it was definitely stuck in the key department, and if Wang Zhengguo wanted to go abroad or something like that in the future, the Foreign Affairs Department would definitely have to handle it.

"The person in charge of Shuhang Optics, Wang Zhengguo. Now it is mainly responsible for all aspects of Shuhang, and if Jiang wants to change glasses or something in the future, our products of Shuhang will definitely be able to satisfy you, which is the purpose of our Shuhang. ”

The latter words were not heard clearly, Jiang Zhongxian was mainly still puzzled by the name of Wang Zhengguo, to say that the young people who can be surnamed Wang in Shudu are rare, and then look at this face and age, and after silently comparing it in his heart, he found that it may really be eight or nine.

Thinking about it, this possibility is really not small, if you can confirm it, it would be the best: "The surname is Wang? I look at this face, but it is very similar to Director Wang, is it..."

"That's my father, but at present, I am working in Shudu, and few people can guess my identity, that is, Jiang Foreign Affairs, you come down from the ministry to work, so you can see through it at a glance. "Since they have all guessed their identities, this is actually not a shameful thing, and they generously admit it.

After confirming his identity, Jiang Zhongxian realized that today was indeed worth the trip, and being able to get to a person with a background like Wang Zhengguo was also a very good opportunity for him, a translator who has worked in the ministry for nearly ten years, although he may not be able to get anything from Wang Zhengguo, but one more friend and many roads, who knows?

"It turned out to be Director Wang's son, so I said, it's really similar. Five years ago, when Director Wang was still working in Shudu, I went to Romania with me to inspect the MiG-21MF fighter project at that time. ”

Different situations have to say different things, but obviously this performance is a little too obvious, although Wang Zhengguo doesn't pay much attention to these, but it is impossible for him to let his father be in the ministry just because he saw Jiang Zhongxian here in Shuhang, and the other party helped to be a translator and let his father be in the ministry.

Jiang Zhongxian also felt that after picking out his identity, the two seemed to be even more inconvenient in terms of speaking, he needed to take care of something, and the other party seemed to want to guard against something, only to find that he seemed to have done something not very wise just now, and he regretted it and had no choice, so now he can only change the topic.

"By the way, I listened to John's words just now, it seems that you are planning to use the PMMA resin material used to make aircraft canopies to make glasses, I remember that there has never been an attempt in this area in China, and you look like you are now doing so, is it already going to be successful?"

Speaking of resin glasses, this atmosphere is not embarrassing, Wang Zhengguo is very confident in this: "The technology has long been mature, foreign countries have had successful experience in this area more than ten years ago, we follow the foreign technical route to go, this is absolutely right! That is, in the second half of this year, our Shuhang glasses products will be fully rolled out, and will be sold on a large scale in the whole country, maybe you can see the glasses printed with Shuhang in the optical store in the imperial capital." ”

In recent days, under the responsibility of Tu Zhenying, the sales of Shuhang's products have been carried out smoothly, and it is more appropriate to directly advertise in several national newspapers and periodicals in China, or it is more appropriate to say that some advertorials are used to carry out large-scale publicity on the toad mirror of Shuhang.

In order to distinguish it from the toad mirror imported from abroad, and also to facilitate production, the frame is directly changed to PMMA material, and the lens not only uses a mature high wear-resistant film, but also the anti-ultraviolet coating that has just made a technological breakthrough has been added to the new toad mirror.

The use of resin frames, naturally in the shape of the design is not so much exquisite, directly copied twenty years later the Republic of Air Force ground staff issued 02 sunglasses, at most only the temples have been partially optimized, improve some side aesthetics, the rest of the design is the original design, which is definitely in line with the face shape of most people in the Republic, is the most suitable design for the volume.

Correspondingly, the official name of this glasses has also been changed to: sunglasses, this name sounds much better than the so-called toad glasses, and it is also more in line with the popular aesthetics of China.
