Before returning to the college entrance examination, I became popular in the science circle

Chapter 245
With constant collision output in his mind, the preliminary structural direction appeared in Wu Tong's mind. Is it possible to weave special steel nanowires into a grid skeleton, and then perform directional filling? The combination of the skeleton and the filler will combine the coagulation force. Expansion and integrated construction can also speed up construction.

Yes, it can be done. The ancients invented yellow mud mixed with straw powder, making the adobe bricks made of mixed materials stronger and more durable. From the same perspective, it is naturally possible to enlarge and reinforce the integrated roadbed of the highway. Passed.

After determining this idea of ​​subject construction, Wu Tong began to transform it into detailed mathematical problems and began to build a thorough mathematical model.
Draw up the upper limit of the data parameters that you want to achieve, and use this to reversely deduce the most suitable weaving density of the grid skeleton and the specifications required for the special steel nanowires...
Using the most appropriate amount of materials to create the best results has always been Wu Tong's stated goal. There should be no waste from the beginning.

The traditional viaduct model is prepared in sections. Steel beams and steel bars are used as the skeleton, concrete is poured as the filling, and asphalt is also paved. However, in this case, the cost is high. Due to landform problems, the price of the Jinguan Expressway directly reached [-] million. A significant price to pay for a kilometer.

In the office of the Materials Research Laboratory, Tao Ran reported the parameter data of various basic materials to Wu Tong, while softly making a brief summary of the data they collected.

"Concrete is one of the most important civil engineering materials in modern times. It is prepared in a certain proportion by cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary. It is uniformly stirred and compactly formed. An artificial stone made by curing and hardening.

The term concrete usually refers to cement concrete that is made of cement as cementing material, sand and stone as aggregates, mixed with water in a certain proportion, and stirred. It is also called ordinary concrete. It is widely used in civil engineering. "

Wu Tong lowered his head and glanced at the summary of the information in his hand, thinking deeply: "Whether it is ordinary concrete in a broad sense, based on the six categories of cement specified in GB175-2007, namely Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and composite Portland cement.

Or special cements with special properties or uses, such as G-class oil well cement, fast-hardening Portland cement, road Portland cement, aluminate cement, sulphoaluminate cement, etc... They are basically silicates product! "

Silicates?Wu Tong's eyes focused again.

Most of these materials have the advantages of high melting point and stable chemical properties, and are widely used in various industries and scientific research.

Various materials and basic structures are commonplace for Wu Tong and are easily accessible.

When the focus was gradually analyzed and directed towards silicate, Wu Tong's pen had quickly sketched out on the draft paper the basic structure of silicate, silicon-oxygen tetrahedron; silicon atoms occupy the center, and four oxygen atoms Occupy four corners.

These tetrahedrons, depending on the tetrahedrons and different combinations, form various types of silicates.

This can also be classified as another form of silicon oxide. Switching it around, this is back to the section she is quite good at. In this section, Wu Tong has enough in-depth research accumulation, and she is naturally more comfortable in deducing it. .

Naturally, ordinary cement structures cannot meet Wu Tong's current vision, even the existing special cement.If there is nothing more suitable now, she will continue to dig deeper until she finds something more suitable.

Low cost, high strength, and high performance. In the field of materials research, Wu Tong has always been willing to pursue higher use effects and is picky.

Seeing Wu Tong writing something quickly as if he had some thoughts, Tao Ran almost held his breath and gently placed the materials in his hands on the corner of Wu Tong's desk, walked lightly, and quietly exited the office.Wu's status is not to be disturbed. This is the iron rule that they have signed a confidentiality agreement after joining Wu Tong's team, and have been emphasized in confidentiality training.

Wu Tong has done in-depth research on the selection and deduction in each direction, and has written countless pieces of draft paper. He has also made in-depth research on the adhesive material literature that he has consulted, as well as the information on this sector at home and abroad. Tong's knowledge base in the field of silicon oxide and special silicides brings new advancements in thinking every day!
Step by step, Wu Tong steadily moved towards the top of the mountain of success.

At the end of June, the final deduction results were presented in Wu Tong's writing, and the chemical formula of sodium chloride silicate - NaCl was finally put down.

Silicate is a chemical term. The so-called silicate refers to the general name of compounds formed by the combination of silicon, oxygen and other chemical elements, mainly aluminum, iron, calcium, magnesium, potassium, sodium, etc.

After in-depth analysis and screening, Wu Tong turned his attention to sodium chloride, which can only be said to be a natural thing.

Other combination directions are not without research value, but on the basis of merger control and cost reduction, sodium chloride is undoubtedly an extremely suitable choice.

In addition to the oxygen element that accounts for the largest proportion in seawater, the next element is chlorine. The metal content in seawater is the highest, and the first one is sodium.

Therefore, the first treatment workshop in the seawater desalination production line is the sodium chloride separation and extraction process.

Although it has only been operating at full capacity for about a month, the desalination plant has already accumulated a considerable amount of sodium chloride reserves. At the current separation speed, the total annual output is estimated to be hundreds of millions of tons. This data, It will also increase several times with the addition of other desalination plants and desalination production lines.

It stands to reason that sodium chloride is the main component of common table salt. Wouldn't it be very useful to directly convert it into table salt?But in fact, this is not the case. Although salt is a necessity, the daily intake required by each person is not much. Even if it is wasted in many cases, China's annual salt consumption is only 700 million tons.

Domestically, conventional salt production has a production base of 4000 million tons.

Compared with the production volume of [-] million units, it can only be said that it consumes a fraction, and only uses fur.Especially after the reform of the mining extraction model was promoted, the bulk consumption of sodium chloride in ore smelting was also simultaneously replaced.

The accumulation of large amounts of sodium chloride reserves will cause environmental pollution if not careful. This is not their original intention.

How to consume these large amounts of sodium chloride is about to become a resource accumulation problem that makes people laugh or cry.

This is actually a feeling that resources are insufficient, there is little extra China, and there is little clarity and burden.
