The petrochemical industry not only includes synthetic fibers, plastics and other derivative industries, but also includes the cracking of petroleum in a broad sense. In particular, China's catalytic cracking, which was the first to be widely used in the world in this time and space, is the undisputed chemical industry. It is precisely because
With this brand-new cracking method, New China will be able to defeat the relatively weak
On the basis of this, we can produce high-quality refined oil with the world's advanced level. And it is worth mentioning that the catalytic cracking method used in China is not the earliest fixed-bed catalytic cracking method in history, but it is a one-step process that directly implements the current equipment and technology.
The most advanced fluidized bed cracking technology that can be applied under the conditions.
However, the foundation of the U.S. refining industry is really good (the octane value of the aviation gasoline produced by the U.S. during World War II was much higher than that of any other major power). Although the fixed bed catalytic cracking method they independently developed is relatively backward,
, but the quality of the aviation gasoline produced is actually slightly better than that produced in China (of course only for a period of time), but there is a certain gap in production efficiency and cost.
However, it was this gap that stimulated Hu Weidong. As early as when fluidized bed cracking technology had just been applied to industrial production, he started researching molecular sieve catalysts. Once successful, he could start research on riser catalytic cracking.
, that is the cutting-edge technology of the 1960s in history, whether it is production
Both efficiency and product quality are significantly better than the fluidized bed catalytic cracking method. Moreover, the application of molecular sieves goes far beyond this one use, and its potential value is simply inestimable. However, if there were not an outstanding talent in this field in China, Hu Weidong would also
I may not be able to make up my mind to make it a priority...
No matter what, relying on the rapid development of the petrochemical industry, China's oil refining capacity has reached the world's advanced level almost from the beginning. It is not like the Soviet Union a few years ago, where crude oil production ranks among the top in the world, but refined oil is still not self-sufficient.
It is precisely because of this foundation that although China now needs to import a large amount of crude oil,
As long as the supply of raw materials is guaranteed, there is no need to worry about refined oil products. Even though China's automobile production exceeded 100,000 units in 1941, tractor production exceeded 150,000 units (including more than 100,000 walking tractors).
The total output of internal combustion engines has approached one million units...
The application of tractors and a large number of agricultural machinery has liberated at least tens of millions of rural laborers. Otherwise, no matter what the Chinese government can do, it will not be possible to maintain more than 8 million troops while carrying out large-scale construction everywhere and continue to ensure the continued increase in agricultural production.
In relatively sparsely populated border areas, the open terrain is suitable for the development of mechanized agriculture. With the help of modern agricultural machinery, it is not difficult for one person to cultivate hundreds or even thousands of acres. Therefore, the reduction of young and strong labor force in rural areas is not a problem.
will have too great an impact. On the contrary, farmers will benefit from the increase in labor productivity.
have generally become richer (as for those laborers who have left agriculture, under the current economic system in China, their income will only be higher than that of relatives and friends who stay in the countryside.); and in densely populated areas such as coastal areas and the Central Plains, even the young and middle-aged people in rural areas
Even if half of the labor is taken away, there will still be more people and less land, so there is no need to worry...
If so much labor is suddenly liberated under a market economic system, the unemployment problem will inevitably break out quickly, because no market can provide tens of millions of new jobs within a year. This is also the result of a planned economic system.
Advantages. In fact, if it is a market economy model, those illiterate or semi-illiterate laborers who have just left the countryside cannot be said to be qualified workers at all, or they cannot be said to be qualified workers at all.
If there is no need for them, or they can only do menial jobs with no technical content, only the planned economy model will tolerate their various shortcomings and patiently pay a huge price to gradually train them into qualified industrial workers.
.Hu Weidong also confirmed once again that for China, which has an extremely weak foundation, if it wants to complete industrialization as soon as possible, the planned economic stage cannot be bypassed...
The production of cement and other building materials, which has already ranked first in the world, continues to develop rapidly under the stimulation of Daxing infrastructure. And because the projects built by the engineering corps are basically designed in accordance with wartime requirements,
Therefore, the technical level and product quality of China's building materials industry have also continued to improve driven by demand. After Hu Weidong learned about these situations, he couldn't help but recall the phenomenon that newly built bridges in later generations often collapsed, but those built before the 1980s were strong.
He sighed somewhat helplessly, "Perhaps in order to deal with those crazy overloading drivers in the future, the engineering corps really cannot be canceled. Designing according to wartime requirements seems to be a waste of a lot of manpower, money and material resources, but considering the overloading problem in the future, in fact,
It's not too much, not too little, it's just right. On the contrary, it's the new construction projects that seem to be more cost-effective after the relocation. The losses caused by the accidents are probably even higher. I don't know if this is our special national situation...
..."
In fact, relatively speaking, the quality of bridges that have frequently suffered accidents in later generations is quite good. If the impact of overloading is not considered or even underestimated, even those bridges that have collapsed accidents are mostly considered qualified. After all, once a bridge accident occurs, the consequences will be extremely serious.
It is serious, so the supervision is relatively strict. In comparison, ordinary residential buildings have bigger problems. Since they are not subject to constant testing like bridges, later generations contracted layers of contracts for the sake of profit. As a result, corners are generally cut and materials are cut. In normal times, we ask
The problem is not big, but when an earthquake strikes, an extremely ironic scene will appear - the older the building, the less damaged it will be. You must know that those old buildings do not need to meet combat readiness requirements like bridges, they are just ordinary buildings.
, in contrast, the quality of construction in later generations cannot be whitewashed in any way. Therefore, Hu Weidong firmly believes that we must nip it in the bud and cut off the possibility of the "layered contracting" model now, so as to avoid the problems in history
The tragedy repeats itself.
However, even if the quality of the building is qualified, without special earthquake-proof design, it will still be difficult to survive a major earthquake of magnitude 7 or above. The historical Tangshan earthquake is proof. For this reason, Hu Weidong specially instructed Minister Li of the Ministry of Geology to temporarily put down the work of prospecting. Anyway,
What has been explored so far
These are enough for China to use until 1980, and let him devote his main energy to the study of earthquakes to find China's main earthquake zones as soon as possible, and classify them according to their threat levels, so as to provide the central government with the overall plan.
