Time Travel: After Seizing the Throne, I Lead the Ming Dynasty to Take Off

Ma Sanbao followed Zhu Yunhuan to the charcoal stove in the Qianqing Palace. He frowned and thought for a moment before saying, "Although no clear memorial has been submitted yet, I remember Commander Song mentioned it to me a few days ago. He said that if Your Majesty asked, I could tell you a little."

"A few days ago, Commander Song said he had received news from Shanxi."

"The high-alumina bauxite has been shipped to Yingtian Prefecture. I roughly estimate the time. A large quantity of high-alumina bauxite should be delivered within the next two or three days."

This matter was transported along the same route as anthracite, so it was not easy to be noticed. Therefore, there was no need for Song Zhong to submit memorials too frequently before the matter was settled.

Zhu Yunhuan nodded: "I think this matter is not difficult to handle. After all, I have even pointed out the specific mountain to them. It is very simple to dig something from the mountain and send it over." This speed was also within his estimation, so he remembered to ask about it today.

He looked at the red charcoal burning brightly in the charcoal basin, raised an eyebrow, and murmured softly to himself: "The high-alumina bauxite has arrived, and we can start calcining the high-alumina bauxite clinker... After obtaining the clinker..."

Having said that, Zhu Yunhuan paused, his eyes fixed, and he picked up the tongs beside him and fiddled with the charcoal in the stove intentionally or unintentionally, as if he was lost in memories and contemplation.

After a moment, he said, "Clinker, for making bricks... we need a binder, which is... sodium wood sulfonate."

The most commonly used binder for refractory bricks is sodium wood sulfonate.

Sodium lignin sulfonate is a natural high molecular polymer, which is mainly prepared by sulfonation modification of lignin. As for lignin, it is widely present in plant cell walls and is actually easy to obtain in nature.

All you need to do is use biomass resources such as wood and bamboo as raw materials, crush them into sawdust or bamboo chips, dry them, then soak the sawdust or bamboo chips in an alkaline solution, heat and stir for a certain period of time, and then filter them to get a lignin solution.

The solution is then subjected to a sulfonation reaction with sulfuric acid to generate lignin sulfonate, and then an inorganic salt such as sodium carbonate or sodium hydroxide is added to precipitate the lignin sulfonate.

The alkaline solutions, sulfuric acid, inorganic salts... and so on.

If it were before, the preparation conditions would still be a bit tight.

However, the Alchemy Bureau has been established for such a long time, and it has gathered a group of people who are closest to modern chemistry in this era. It is enough for Zhu Yunhuan to explain some basic chemical concepts in junior high and high school to them.

in short.

The cattle and horses are basically capable of performing the job functions he needs!

The preparation of four salts, three acids and two bases is no longer a difficult problem, let alone an alkaline solution.

Let them handle this so-called sodium wood sulfonate, as they are very professionally qualified.

Zhu Yunhuan seemed to have remembered something else. His eyes, which had been a little blurry due to his deep thought, refocused, brightened slightly, and a faint smile appeared at the corner of his mouth.

He casually tossed the fire tongs aside, stood up, and said, "It just so happens that this sodium wood sulfonate is used for more than just a binder for refractory bricks. Or rather... being a binder for refractory bricks is just its most insignificant use."

"Sanbao, I have to go to the Alchemy Department."

The greatest role of sodium wood sulfonate is actually as a water reducer for cement and concrete. It can not only greatly improve the fluidity and plasticity of cement and concrete, but also greatly reduce harmful pores and significantly enhance compressive strength!

This time, the anthracite supply is much shorter than expected, partly due to the speed of coal washing and partly due to transportation.
