Chapter 244: Strange
With constant collisions and outputs in his mind, a preliminary structural direction appeared in Wu Tong's mind. Is it possible to weave special steel nano-wires into a grid skeleton, and then carry out directionally filling? The combination of the skeleton and the filler can expand and amplify the solidification force, and integrated construction can also speed up the construction speed.
Yes, it is feasible. The ancients invented yellow mud mixed with straw crumbs, which made the earth bricks made of the mixed materials stronger and more durable. From the same perspective, it is naturally feasible to enlarge and reinforce the integrated roadbed of the highway.
After determining this subject construction idea, Wu Tong began to transform it into detailed mathematical problems and began to build a thorough mathematical model.
Develop an upper limit for the data parameters that you want to achieve, and use this to reversely deduce the most appropriate weaving density of the grid skeleton and the required specifications of the special steel nanowires...
Using the most appropriate amount of materials to create the best results has always been Wu Tong’s established goal. There should be no waste from the beginning.
The traditional model of preparing elevated bridges in sections uses steel beams and rebars as the skeleton, concrete as the filling material, and asphalt. However, the cost is relatively high. Due to the topography, the Jinguan Expressway directly reached a huge cost of 200 million yuan per kilometer.
In the Materials Research Office, Tao Ran reported the parameter data of various basic materials to Wu Tong, and quietly made a simple summary of the information they collected.
"Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone made of cementitious materials, granular aggregates, water, and admixtures and additives added in a certain proportion, which are uniformly mixed, compacted into a compact shape, and cured and hardened.
The term concrete usually refers to cement as a binder, sand and stone as aggregates, mixed with water in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.
Wu Tong looked down at the summary of the materials in his hand and pondered: "Whether it is ordinary concrete in a broad sense, based on the six major types of cement specified in GB175-2007, namely silicate cement, ordinary silicate cement, slag silicate cement, pozzolanic silicate cement, fly ash silicate cement and composite silicate cement.
Or special cements with special properties or uses, such as G-grade oil well cement, fast-hardening silicate cement, road silicate cement, aluminate cement, sulphoaluminate cement, etc....basically all silicate products!"
Silicate? 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.
For Wu Tong, various materials and basic structures are all commonplace and easy to use.
When the focus was gradually analyzed and oriented to silicates, Wu Tong's pen had already quickly sketched out on the draft paper the basic structure of silicates, a silicon-oxygen tetrahedron; the silicon atom occupies the center and four oxygen atoms occupy the four corners.
These tetrahedrons, based on tetrahedrons and based on different coordination, form various types of silicates.
This can also be simultaneously classified as another form of silicon oxide. After a conversion, this returns to the area she is still good at. In this area, Wu Tong has accumulated enough in-depth research experience, so she is naturally more adept at deducing.
Ordinary cement structures naturally cannot meet Wu Tong's current vision, even if it is the existing special cement. If there is no more suitable one, then she will continue to dig deeper until she finds a more suitable one.
Low cost, high strength, and high performance. In the field of material research, Wu Tong has always been keen on pursuing higher results, even the most meticulous one.
Seeing that Wu Tong seemed to have some inspiration and was writing something at a very fast speed, Tao Ran almost held his breath immediately, gently placed the documents in his hand on the corner of Wu Tong's desk, lightened his footsteps, and tiptoed out of the office.
Wu's state cannot be disturbed. This is an iron rule that was emphasized during the confidentiality training and the confidentiality agreement they signed when they joined Wu Tong's team.
Wu Tong screened and deduced each direction, and wrote countless sheets of draft paper. He also conducted in-depth research on the adhesive material literature he had referred to, as well as the information on this field at home and abroad. In addition, Wu Tong's knowledge reserves in the field of silicon oxide and special silicides led to new progress in thinking every day!
Wu Tong steadily moves towards the peak of success step by step.
By the end of June, the final deduction result was presented by Wu Tong's pen, and the chemical formula of sodium chloride silicate - NaCl was put to the final touch.
Silicate is a chemical term. Silicate refers to the general term for 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, it was only natural for Wu Tong to turn his attention to sodium chloride.
Other combination directions are not without research value. On the basis of controlling costs through mergers and acquisitions and minimizing costs, sodium chloride is undoubtedly an extremely suitable choice.
In addition to oxygen, which accounts for the largest proportion of the element in seawater, the next element is chlorine. The metal content in seawater is the highest, with sodium ranking first.
Therefore, the first processing 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 reserve of sodium chloride. At the current separation rate, the total annual output is estimated to be over 100 million tons. This figure will 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. Isn't it useful to convert it directly into table salt? But in fact, it is not like that. Although salt is a necessity, the daily intake per person is not much. Even if it is wasted in many cases, China's annual salt consumption is only 7 million tons.
In China itself, conventional salt production has a production base of 40 million tons.
Compared with the production volume in billions, it can only be said that it consumes a fraction of it and uses only the tip of the iceberg. Especially after the reform of the mining extraction model was promoted, the major consumption of sodium chloride ore smelting was also replaced synchronously.
The accumulation of large amounts of sodium chloride reserves could cause environmental pollution if not handled with care, which is not what they originally intended.
How to consume this huge amount of sodium chloride is about to become a resource accumulation problem that will make people laugh and cry.
This is indeed a perspective that China feels that resources are insufficient, there is little surplus, and there is little clear burden.
