Sitting quietly under the tree, considering all kinds of material issues related to translucent parts, this is not only about traditional silicate optical materials, but also about newer translucent materials.

"In addition to the research and development of high-end silicate optical materials, I see that other types of optical materials must not be relaxed, for example, we now use PMMA resin materials to make glasses, but foreign countries have long been phased out of this backward products, including John said before, Europe and the United States have put the main energy into PC materials, I think we have to keep up." ”

The importance of PC materials is self-evident, Wang Zhengguo has systematically analyzed the impact of this thing on the future of Shuhang, since today is just talking about the next step of the optical laboratory's scientific research planning, then simply talk about the problem directly, so as not to study this stubble separately in the future.

Wang Zhengguo has too many things to do in the future, and if he doesn't do it well, he will forget about it, and it will be difficult to say when he is really in a hurry.

"The development of PC materials? Are you afraid that the semiconductor chip industry, this gold-swallowing monster is not enough for you to toss, and now you are ready to invest in the chemical industry? Let's not talk about the industry's R&D investment, to put it bluntly, these are some technologies that have been announced to the same, R&D I am sure that the investment is not much, when the time comes, I will join the relevant majors of the school, at most one or two million can get the process flow, come up with qualified materials, but when it comes to the production of chemical products, it is different. ”

The production of chemical products belongs to the super-large investment industry, the construction of a high-standard large-scale chemical plant, which is not less expensive than the construction of a large-scale chip factory, the more chemical products used daily, the more its production, and no matter what the product, the larger the production scale means the lower the unit cost, which is more obvious in the field of synthetic chemicals.

The most typical belongs to ethylene production, that thing is the most widely used plastic, plastic stools, plastic bags use ethylene as raw materials, and its production is not the general country and companies can get it, the Republic is also after 2000 to organize major national research projects to achieve the full localization of ethylene equipment, and then large-scale launch of some hundreds of thousands, even millions of tons of annual output of super ethylene plants.

After the completion of these factories, it is indeed very profitable, but its investment in production equipment and factory construction is also astronomical, and in the context of large-scale localization of equipment 20 years later, the investment in building a million-ton ethylene plant is still tens of billions of dollars.

If the value of the currency more than 20 years later is discounted from the value of the currency in the 80s, even if it is a hundredfold difference, it is now an investment of hundreds of millions of yuan to move.

Of course, the fact is that inflation in the eighties and more than twenty years later is far from reaching a hundredfold level, and it has to be taken into account that the large chemical equipment for the production of ethylene in the eighties could not be domestically produced, which creates a problem: the cost of building a large chemical plant in the eighties is definitely more than a few hundred million.

Wang Zhengguo still doesn't know the high investment in the large-scale chemical industry in the 80s, but Professor Liu knows it very well, and he still clearly remembers the newspaper he saw a few years ago about the Yanshan large-scale ethylene chemical project, and the money that guy spent was simply unblinking.

"Let's put it this way, five years ago, the Yanshan 300,000 tons of ethylene project, it cost nearly 5 billion US dollars at that time, although this money also involves the introduction of various technologies, but these digressions are not important, at least it proves one point: the large chemical industry does not have more than one billion investment, completely unable to turn. ”

A very exaggerated figure, think about the 70s spent nearly 5 billion US dollars to introduce foreign technology to build 300,000 tons of ethylene project, although it is not clear how the 5 billion US dollars of foreign exchange came from at that time, whether there was a foreign loan factor, but this data is absolutely huge.

Even Wang Zhengguo, a guy thirty years later, listened to it, and still felt stunned for such a huge project, which is really bold enough, at that time, it may only be through the endorsement of the state to develop such a large super project, and then think about the current financial situation of Shuhang, it is really too small.

Fortunately, I was not completely bluffed by the huge cost of petrochemical engineering, so I shook my head vigorously, remembering that the two products of PC material and ethylene are fundamentally different, and I was able to regain some confidence a little.

Until the time of rebirth, the total annual consumption of PC materials in China was only more than 100 tons, and the total output of the entire international market at that time was only 3 or 400 tons. Push back to 2,000 years, and the annual domestic consumption is only 200,000 tons, which shows that PC materials and vinyl materials are not a level of demand at all.

It can be inferred from this that if it is really in the eighties, how low is the domestic demand for PC materials, it may be worth more than tens of thousands of tons, such data seems that the domestic production cost is even less cheap than imported abroad, anyway, this thing is a civilian bulk industrial raw material, even if Western countries embargo it in the future, it will not be stupid enough to prohibit the export of this kind of thing.

"I roughly calculated, if it is just to meet our own special needs of Shuhang, then even if there is a production of dozens of tons a year, it seems that it is not impossible to adopt the import model. But there is a problem, the PC materials we need to use are different from the ordinary PC materials on the market, we are doing the optical industry, and even the military industry and national defense, so the products will have special performance requirements, which must not be imported anymore, so we can only find our own way to produce. ”

Considering these problems, Wang Zhengguo feels that even if he wants to prepare for Shuhang to take the lead in building a PC material factory to meet his own needs, it does not seem to be too difficult, compared with the output of the ethylene project, which is often billions of tons of factory output, the PC output at this time is simply incomparable.

Ordinary PC materials are used for automotive translucent parts, optical discs, and disposable medical devices, which do not have extreme optical performance requirements, but to make glasses and camera translucent parts, this must require high optical quality.

If you want to say ordinary PC materials, foreign countries may not prohibit the Republic from importing them, but optical-grade products, which obviously belong to the category of embargo, and even the companies that produce these optical-grade PC materials will not sell them to the outside world at all, and they are directly produced and sold by optical giants.

Obviously, Wang Zhengguo's concern about this question is very necessary, and the professor fell silent for a while, he is also in the optical industry, and knows that as long as it involves high-end optical materials, almost all of them are secrets developed by the optical giants themselves, and it can only be a fool's dream to import.

Got up from the stone pier, looked across the river with his eyes, and sighed: "What you said is not unreasonable, what we need are optical-grade high-end products, and some of them will be supplied to the military in the future, and the army will definitely have requirements for the autonomy of raw materials, so we must produce it ourselves, not only to have excellent optical performance, but also to have good protection capabilities." ”

Hearing this, Wang Zhengguo suddenly wanted to laugh, how do you feel that in the end you are still working for the army's scientific research, you said that this has excellent protection capabilities and optical performance at the same time, isn't this just to let the army take a big advantage, it seems that Shuhang's military identity is doomed, no way.

As for production, it is expected that a special PC material factory with an annual output of 100 tons should not cost much, at most a budget of one or two million yuan, let's sum up the money, as long as Shuhang is currently developing smoothly, it may be a year's profit, and it is probably acceptable. ”

In this way, the professor is generally clear about the profitability of Shuhang, and also knows what the successful production of new optical-grade PC materials means for Shuhang, not to mention the investment of 10 million, even if it is 20 million or 30 million, it can be easily earned.

Turn over and ride a bicycle: "Let's go, what you said are understood, I will start to arrange the relevant work after I go back, and strive to complete the relevant preliminary research as soon as possible, in fact, our domestic PC materials should be regarded as starting at the same time as abroad, the gap is not big now, as long as the money is put in place, we can quickly produce results." ”
