The emperor is not a long-term place, for Wang Zhengguo, Shudu, which has a certain foundation for development, is the place where he can show his strength, and he took his father to give 8,000 yuan, and after a long and difficult trek, he finally returned to the familiar city.

It has been more than half a month since the last time I left Shudu, and in the eyes of the eighties, such a business trip is really not long, and it can already be regarded as a very efficient business trip, after all, it is a journey across most of the republic, and it will take at least ten days on the way alone, not to mention staying in the imperial capital for a while.

Put away the funds in your hand, go to the laboratory to see the situation after washing, there is a certain existing process technology for reference, I believe that half a month has passed, there should be certain technical achievements to be made, but if you can produce the final full set of technical achievements one day earlier, Wang Zhengguo feels that it should be celebrated.

Or the familiar laboratory, from the outside it does seem a little too tattered, but when you open the door to see the internal furnishings, this is obviously another world, with a world of difference to describe it is not an exaggeration, all kinds of temporary equipment moved from the light transmission factory has been installed in place, compared to the previous laboratory scattered a few backward old equipment, this does not know how many streets to get rid of.

The equipment is installed in place, which means that the scientific research work of the laboratory must have begun, it seems that the light transmission factory is quite efficient, I think Ding Yibo must be interested in this matter, he used the big flicker technique very well, but I don't know what Ding Yibo's ambition wants to make optical lenses, what is the situation now.

All kinds of questions need to be answered as soon as possible, and the source of these news will naturally be obtained from Liu Sanshi, I believe that with this guy's sensitivity to all kinds of intelligence and gossip, he will write down these things that Wang Zhengguo cares about these days.

Walking into the laboratory, changing into a work clothes, you can see the experimental operation table in front of you, the professor and Liu Sanshi are working, it looks like they are doing a hardness test, the hardness of PMMA material is not very high, so the surface wear resistance is relatively low, which is a big technical difficulty.

Finally, with a sigh, the professor continued to frown: "The hardness of this PMMA material is always too low, and it cannot reach the hardness level required by optical lenses.

Liu Sanshi saw the person who was already standing aside, and also put down the data registration manual in his hand, and happily greeted him, he has lived a very fulfilling life in the laboratory these days, and has been exposed to a lot of things that were completely impossible to operate in school before, and he has gained a lot.

"Jeongkook, you're finally back, and the imperial capital has already been done?"

"No problem, I've finished dealing with the imperial capital, and this time it's decided, let's do a good job in Shudu." What's the situation on the lab project recently, and is there any progress?"

Paying attention to the technological progress of the laboratory, he did not talk too much, and went straight to the point, asking about the technical progress first. But when it comes to the results, it's obviously not very satisfying, and there are just too many problems.

"In terms of technology, we did encounter problems, the hardness of PMMA material is far less than silicate glass, if you want to use it as spectacle lens material, the current process technology is definitely not good, we have tested the new process, but there is still not much gain, maybe we need to change the way of thinking, ready to use the surface coating method to try to solve the problem of lens surface hardness. ”

Optical lens coating is a solution to the inherent defects of various materials, as early as World War II, the German Zeiss company invented practical optical glass coating technology, which is why the optical equipment of the German army in World War II is usually better than the Allied optical equipment One of the reasons, because the Allied forces did not have this technology at that time.

After the war, the Republic also successively obtained the most advanced optical coating technology from the Soviet Union and East Germany in the fifties and sixties, and then continued to use it until the seventies and eighties.

"In the previous scientific research projects done in the laboratory, some of them have involved coating technology, you can look up the experimental log in August last year, then there is a technical information record about coating, which is relatively detailed. But having said that, the domestic coating technology is developed for silicate glass coating, if it is used in PMMA materials, I am afraid that we will encounter some unexpected problems, you must pay attention to this, but I think the coating should be the best solution to solve the problem of material surface hardness. ”

Speaking his own opinions in a timely manner, Wang Zhengguo still remembers very clearly that on the resin optical lenses of later generations, coating is simply commonplace. What high-hardness coating, anti-blue light coating, anti-ultraviolet coating, and other coating technologies, it is simply to wear layer after layer of clothes for the lens, and pull out a pair of better glasses at random, at least two or three layers of film, if it is a little better, it is seven or eight layers, or even two digits are possible, it is really crazy.

Since we know that coating is the solution to the problem, we should directly put this matter out and tell the experiment here, and bury ourselves in the research of coating technology, I believe that it will not be long before the problem can be properly solved.

"Okay, I'll go find the information you said later, I and the professor have been thinking about the coating problem for a long time, and you don't have to worry about the technical aspect for the time being, now you come with me first, this has an important situation for you, which is related to the future laboratory renovation funding you said." ”

God mysteriously pulled people aside, Liu Sanshi's heart was actually anxious like an ant on a hot pot, since he inadvertently got the news three days ago, he has been anxious, but Wang Zhengguo hasn't come back for a while, and he didn't dare to tell the professor directly, at least after he got along these days, with the professor's personality, he will definitely not be able to properly deal with the current problem.

Seeing Liu Sanshi's action, he knew that something must be wrong, and he just hoped that it wouldn't be too tricky.

"Tell me, what's the situation?"

Liu Sanshi sat down at this time, and pulled Wang Zhengguo to sit opposite: "The woman who was in charge of docking with our laboratory at the Transluminous Factory three days ago was called Tu, anyway, I can't remember what it was called, but that's not the point." The real point is that she accidentally said that the translucent factory has now started a small batch trial processing of PMMA lenses, although without our technical support, their products are not qualified, but they have fully started the progress in related processing and manufacturing, which is a great threat to us!"

Sure enough, there is nothing good, although I have worried about this aspect before, but I really didn't expect that the light transmission factory can be so vigorous and resolute, and directly start the upgrading and transformation of the relevant production lines, which is simply a god speed, when is the efficiency of large state-owned enterprises so high?

It stands to reason that this shouldn't be the case, what the hell is going on, there must be something wrong with it.
