The frost weather is getting worse, and the thermal power plant in the Steel Industrial Park has begun to provide heat to users, including town offices, schools, some enterprises and shopping malls, as well as the two well-off villages in the north and south.

Chen Lidong did not sit at Donghua headquarters to perform the duties of general manager for Luo Hao.

Wen Xiaoyu has been transferred to Bao Ma. Her position in Dongping District has been removed and she has been given a casual position in the city.

Luo Hao returned to work before his son was one month old. He just left the business trip to others and returned home a little earlier every day.

Jinxin Steel Works was acquired by Donghua as expected. It is said that the original owner Li Lixin went to the west and started mining in partnership with others, and would come back when it became prosperous.

The Jinxin Steel Plant is really going to be demolished, but instead of building a park or digging an artificial lake, a product monitoring center and a library will be built.

This made Donghua's senior management a little puzzled. The Product Monitoring Center had heard that some foreign companies had such a setup.

What is the use of building a library? To help employees study for further studies and enter college? There is a primary school to the east of it. Should it be opened to children?

Chen Lidong did not explain, and left the construction to the mechanical servants. They built a fence around the steel plant wall, and then began to dismantle the workshop. The subsequent construction will be kept secret.

That location is right next to the giant statue. Now the statue is dark and lying alone. In fact, it would be good to build a small park around the statue.

At this time, Chen Lidong was listening to the report of the basalt fiber project research team at the Donghua headquarters.

It was said to be a report, but in fact Chen Lidong and others were listening in the audience.

The speaker's name is Ma Wenbiao, Lao Ma's son.

Ma Wenbiao studied at the School of Engineering at Alfred University in Samoa, studying ceramics and glass. He worked for Corning for a period of time. He planned to work at Yanjing Corning Optical Cable a few years ago, but the headquarters did not include him in the list of returning to China.

Ma Wenbiao resigned from Corning in anger and wandered around for two years. After his non-compete agreement was terminated, he settled in Donghua's scientific research center.

After this guy came to Donghua, he has been obsessed with the purification of graphene. Based on the original graphene oxide, Donghua has successfully applied for a number of patents in the field of graphene since last year, all of which are the contributions of Ma Wenbiao's team.

Major events in his life have always been Ma Jianguo's worry. He is almost 40 and still hasn't gotten married or had a girlfriend. He has either physical or psychological problems. Lao Ma is worried about getting the reputation of being a "desperate family".

After Sun Lan received the topic of improving the basalt fiber production process explained by Chen Lidong, he announced it to various teams in the research center. Ma Wenbiao just had time these days, so he applied for this topic.

...

Now, Ma Wenbiao stood on the podium and talked eloquently: "The leaky plate is an important tool for drawing glass fiber and basalt fiber.

Theoretically, the process for making basalt fiber is the same as that of glass fiber, and it is feasible for fiberglass factories to directly switch to basalt fiber production.

As mentioned before, one of the costs that affect the production of basalt fiber is the price of electricity and the other is the cost of materials. The main consumption of materials is leakage plates.

The shape of a drain plate is a trough-shaped container, like a kitchen sink. The bottom of the sink is full of holes, and these holes are called drain spouts."

As Ma Wenbiao talked, he drew a sketch of the leaky board on the writing board, and then continued:

“During the wire drawing process, the molten liquid flows into the vegetable sink, is adjusted to a suitable temperature in the vegetable sink, and then flows out through the drain spout at the bottom.

After flowing out, it is stretched into continuous fibers by the high-speed rotating wire drawing machine below. It is stretched and thinned at the same time, and then cooled by the cooling device into fiber filaments of the required diameter."

At this time, there is already a simple drawing of the wire drawing machine on the writing board, which is then combined with the drain board to form a process architecture diagram.

Ma Wenbiao continued: "The drain plate is a key component in the production of glass fiber and basalt fiber.

After decades of research and exploration in the selection of leakage plate materials, only platinum-rhodium alloys can be widely used in glass fiber production.

Clay and other heat-resistant alloy materials cannot withstand the erosion of high-temperature glass liquids, while drain plates processed from platinum-rhodium alloys can withstand the erosion of high-temperature molten liquids and have strong creep resistance.

Creep is a phenomenon in which the strain of a solid material increases with time under the condition that the stress remains unchanged."

At this point, Ma Wenbiao looked at the audience and said, "I won't elaborate on the mechanism of creep here. It's a bit abstract and complicated, and it would be too troublesome to explain."

Chen Lidong and others looked at each other and said to themselves, "I'm worried that I won't understand. This is because I'm being looked down upon."

Ma Wenbiao knocked on the writing board and continued his explanation:

"Platinum-rhodium alloy is an alloy material composed of platinum as the main material and a small amount of rhodium mixed in.

Although pure platinum material has strong high-temperature oxidation ability, it has poor creep resistance. If the drain plate is only processed with this material, the deformation problem will be difficult to solve, let alone extending the life of the drain plate.

However, after adding a certain amount of rhodium to pure platinum, the mechanical properties of this platinum-rhodium alloy have been greatly improved, improving its own creep resistance and basically meeting the requirements of leaky plates.

I won’t go into detail about the size, accuracy, and spacing of the drain nozzles when processing platinum-rhodium alloys. With Donghua’s precision machining standards, there is no problem.

The following focuses on the anti-oxidation coating treatment process of platinum-rhodium alloy drain plates studied by our research group.

Platinum-rhodium alloy is to add rhodium to the platinum material. The rhodium content is about 10% to 20%. The purpose of adding rhodium is to further improve the high-temperature strength and anti-oxidation, anti-corrosion and anti-creep performance of the drain plate.

Platinum and rhodium are both precious metals. The current price of platinum is US$372 per ounce and the price of rhodium is US$570.

In recent years, the price of platinum has been generally stable, while the price of rhodium has fluctuated greatly.

The reason why people further improve the process is to improve the oxidation resistance of the platinum-rhodium alloy drain plate, reduce consumption and reduce costs.

The solution provided by our research team is to use thermal spraying to spray ceramic oxide onto the surface of the platinum-rhodium alloy drain plate to form an anti-oxidation coating to reduce the oxidation and volatilization of the drain plate at high temperatures.

Impact resistance of coatings formed by thermal spraying methods

Strong, melted and semi-melted ceramic oxide and roughened platinum matrix are mechanically fitted and physically and chemically combined. The bonding strength is relatively strong, and the coating will not crack or fall off, ensuring that the drain plate has good surface stability.

sex.

Experimental results show that the loss of the drain plate treated by the above method can be reduced by more than 50% compared with the untreated drain plate. "

At this point, Ma Wenbiao put down his writing pen, said that he had finished the report, and walked off the stage.

Chen Lidong took the lead in applauding. Reducing losses by 50% is definitely a great innovation.

When Ma Wenbiao walked up to Chen Lidong, he added: "We use the method of spraying ceramic oxide because of the tip from Mr. Chen, who once suggested whether to use a ceramic drain plate.

Although ceramic drain plates are not feasible, it also made us consider the application of ceramic materials first."

Chen Lidong said somewhat smugly: "I just say that from time to time, it's all because of your hard work.

Oh...this...will it be unusable after the leakage plate is damaged?"

Ma Wenbiao had already sat next to Chen Lidong and said expressionlessly: "Such valuable things must of course be recycled. my country's platinum-rhodium alloy recycling and processing technology is still very advanced, and the recycling rate can reach more than 95%."

Chen Lidong was a little stupid when he heard it. According to his idea, if the platinum-rhodium alloy recycling effect is not good, he can start black.

How to open black? Use the system furnace!

Recycling with a system furnace is simple enough, with a recovery rate of 80%, but Ma Wenbiao said that others can achieve 95% or more, which leaves no room for the system furnace to play.

For such a precious metal, just one percentage point is worth a lot of mani.

Just listen to Ma Wenbiao say: "In fact, our innovative process only extends the use time of the leakage plate. In the entire industry chain, the consumption of platinum and rhodium alloys is not that exaggerated.

The main reason is that my country's platinum and rhodium metal mineral reserves are too small, the taste is too poor, and it relies heavily on imports.

If our mining department can discover high-quality mineral deposits, or if you can mine platinum and rhodium metals from abroad, it will be possible to reduce costs.

Oh... Actually, there is another way to reduce investment."

Chen Lidong asked with admiration: "Which way?"

“Leasing platinum and rhodium metal is a method that some foreign companies are adopting.

It is a leasing/purchasing method, leasing two metals from the bank, and the factory only needs to pay the rent, which can avoid the risk of market fluctuations of the two precious metals."

"Oh... we are not short of money." Chen Lidong said casually, and the people present burst into laughter.

Basalt fiber will be included in Donghua's production plan for next year. With this material, fiber can be used to weave cloth and provided to special industries; fiber and resin can be used to synthesize panels to make automobile panels and high-speed train insulation panels; winding rods

, make light poles for wind and solar lamps; use extrusion to make photovoltaic cell components; add them to concrete to increase strength and support the upcoming highway construction...

Someone who was reborn was ambitious and was waiting for this material to be put into production.

Where is the factory located?

I plan to place it in Panshan, right next to the port, because a new power plant is being built there and it will use its own electricity and the price is good.

However, Chen Lidong was also interested in mining.

Ma Wenbiao is right. If you have platinum or rhodium mines, you can control the price from the source.

He has a system furnace, which allows him to take shortcuts in mining, especially since the system also has a long-term task: collection. Mining 12 tons of platinum can be exchanged for a mechanical servant.

So Chen Lidong went to the China Geological Survey to learn more.

Since Donghua started mining in Changlong a year ago, it has had business cooperation with the Geological Survey Bureau.

The bureau attached great importance to his arrival. It was heard that he wanted to know about the distribution and mining situation of platinum deposits abroad. Although he was a little disappointed, he helped Donghua invite experts from the Academy of Geological Sciences to provide them with special guidance.

The visitor was Gu Yaoshan, the head of the Mineral Research Institute. He held a stack of information in his hand and introduced it to everyone.

“The largest platinum-producing countries in the world should be the Rainbow Country, the Woolly Bear Country, and the Kangaroo Country in southern Africa.

I know more about the situation of the woolly bear. Last month, I participated in the international symposium on "Metal Mineralization, Petroleum Resources and Geodynamics of the North Asian Craton and Fold Orogen". The country of the woolly bear invited experts to discuss

Relevant topics were discussed.

Norilsk, the Ural and Aldan regions are the main platinum group metal producing areas of Mao Xiong.

In addition, judging from what they introduced at the seminar, the Anabal Shield area may become a new platinum group metal production area for Mao Xiong.”

Chen Lidong interrupted and asked: "Anabal Shield? Where is it?"

Gu Yaoshan looked up at the conference room, then stood up and walked to the hanging world map. Chen Lidong and others also walked over.

Gu Yaoshan pointed to an area between two rivers near the North Pole and said, according to the information introduced by Mao Xiong mineralogist, the new platinum area should be here.

Chen Lidong was frightened when he saw it: "It's too remote here. Is there anyone here?"
