Material Empire

Can I try this blade? Hibbs couldn't pretend to be reserved anymore, he couldn't wait to ask Qin Hai.

Qin Hai said with a smile: Please go ahead, but you have to be young...

Before he could utter the word heart, he saw a tinge of red on Hibbs' finger. This unbelieving guy actually tried the edge of the rake with his hand, and was wiped out cleanly. A hole was opened.

It's impossible! Hibbs yelled out of composure, How did you solve the problem of ceramic blades!

Everyone knows that ceramics are a highly wear-resistant material, and there is also a team at Tolfson Company working hard to solve the problem of ceramic base parts being edged. Or to be more precise, it is to study how to make ceramic utensils thinner under the premise of ensuring strength.

Ceramics are fired from china clay. China clay itself is not very viscous. If it is made too thin, it will be easily damaged. In order to improve the viscosity of china clay, ceramic scientists try to mix colloid into china clay to turn china clay into viscous clay, and then make thinner utensils by extrusion or forging.

After the utensils are formed, they must be sintered, which is an indispensable process in ceramic production. During the sintering process, the colloid in the china clay will evaporate due to high temperature, leaving only the china clay to be transformed into ceramics through kiln. The problem lies in the evaporation of colloids. After these colloids evaporate, countless tiny holes will be left in the china clay, which will reduce the strength of ceramic products and may even leave hidden dangers of foreign matter penetration.

Without being able to solve the above technical problems, Tolfson's engineers have never been able to manufacture thin enough ceramic rakes, let alone sharpen the ceramic rakes. However, the ceramic rake that Qin Hai took out actually opened the blade, and Hibbs proved a few points with blood: first, the blade is thin enough; second, the surface of the blade is very smooth; Third, the material is dense enough that none of the blood from Hibbs' hand seeps into the ceramic. It can be seen from the latter two that the Chinese have already solved the problem of the tiny holes after the gel evaporates.

This disc rake is a new product developed by Qin Hai under the direction of Quwu Brothers Ceramics Factory. Its porcelain clay uses nano-sized zirconia powder, and a special gel is added for compaction processing. Using this gel, combined with a special sintering process, can ensure that the body will shrink when the gel evaporates, thereby eliminating the pores of the gel and obtaining dense and high-strength ceramic products.

Qin Hai spent so much energy developing this new process, of course it was not for the production of disc harrows. In fact, it is too extravagant to use nano-scale zirconia materials to make disc harrows. Qin Hai's target is a very popular household item in later generations - ceramic knife.

The hardness of zirconia ceramic knives is second only to that of diamonds, and it can be used in the home environment almost to the point of never wearing out, and it does not need to be sharpened frequently like metal knives. In addition, ceramic knives are beautiful, easy to clean, never corroded, and do not produce the fishy smell of ordinary metal knives when cutting food. They quickly became popular all over the world in the early 21st century.

Last time, Liu Shuo and Huang Yanling came to Qin Hai's home and proposed to enter the civilian ceramics market. Qin Hai had an idea and thought of such a magical tool as a ceramic knife, and then instructed them to make actual samples. In order to be able to borrow a platform like the Agricultural Machinery Exhibition, he specially asked Liu Shuo to make a few ceramic disc harrows. Although they are overkill, they are worth the money for advertising.

The various twists and turns in the middle, Qin Hai naturally will not explain too much to Hibbs, seeing the blood on Hibbs' hands, he said sorry gloatingly, and then handed the blade to Hibbs Ask the staff to let the other party include it in the scope of the test.

How is this possible? Hibbs was dizzy, he almost doubted what he saw, but the blood on his hand reminded him that all this was true.

Mr. Qin, is this ceramic harrow the product you're talking about that didn't reach the upper limit of durability? Hibbs asked.

Qin Hai nodded and said: Yes, due to time constraints, we have not been able to complete the test of its durability limit, but in our test, the same piece of harrow has withstood the durability test of more than 500 hectares. There was no significant wear and tear on the body.

This is natural... Hibbs murmured, the wear resistance of ceramic materials is not comparable to that of metals. If steel can only wear 100 hectares, it is not surprising that ceramics can reach 500 hectares.

Can you tell me what kind of ceramic this rake is made of? Hibbs asked again.

It's zirconium dioxide, and there are some traces. Qin Hai replied readily.

Qin Hai intends to trade ceramic knives, so the main material of the knives must not be concealed. What's more, this kind of thing can't be hidden either. Someone can just buy a knife and conduct a test to analyze it. The real technical secret of ceramic knives lies in the gel and sintering process used by Qin Hai. It took countless people 20 years to solve the problem. Qin Hai only crossed this technology with the help of a cheating device like time travel threshold.

The gel has evaporated during the sintering process, and others cannot explore its composition from the knife. The sintering process is even more tricky. There are millions of combinations of temperature and time. Unless industrial spies can be sent to spy, no one can guess it out of thin air.

The durability test is done anytime. After Qin Hai sent all the basic parts in, the staff started the equipment and started the test. Although the evaluation standard is the durable life of the foundation parts in soil operations, the real test is not carried out on the land, because experiments involving hundreds of hectares are unacceptable in terms of time and cost.

The test method used by the organizing committee is to put the basic parts in a machine to make them rotate at high speed, and then contact them with friction materials to calculate the wear speed of the basic parts. Such a test can simulate the effect of hundreds of hectares of farming operations in a relatively short period of time, and for the sake of intuition, the final test results are also presented in terms of the operating area.

The venue of the entire expo is large, but the circle of people is very small. These manufacturers of agricultural machinery have more or less connections with each other. The Chinese brought some basic parts produced with special materials and special techniques, and claimed that they could exceed the world's advanced level. Such a news quickly spread throughout the venue. As a result, before Cui Hongchun took people to set up the booth, there was already an endless stream of people who came to visit and communicate. You know, the real launch time is tomorrow.

Sir, how is the surface of your knives treated?

Excuse me, is this a pure ceramic knife? Oh, sweetie, how did you make the ceramic so thin?

Can I cut paper with it? Look, it's sharper than a paper knife...

I visited your country three months ago, but we didn't hear any news about these knives at that time. Did you deliberately block the news?

I would like to know, do you need an agent in the European market...

People of various skin colors gathered in front of the booth of the Chinese delegation, looking at the various basic components displayed on the booth, and asking the Chinese people in the booth to ask questions. This made everyone embarrassed. In this group, apart from translators, there are five people who can speak English, including two high school students, Tranquility and Qin Shan. Compared with those factory directors in their 50s, Tranquility and Qin Shan are almost super good in English.

Little girl, listen to me, what are they talking about? Zhu Detai, the director of the Northern Agricultural Machinery Factory, brought Qin Shan to his booth, and pointed at the two chattering chatterboxes. The white man said in a begging tone.

Uncle Zhu, my English is not good... Qin Shan replied in embarrassment.

Zhu Detai didn't have the demeanor of an elder at all, so he said with a stern face: No matter how bad your English is, it's much better than your Uncle Zhu... Alas, if I knew this, I wouldn't come out to show this eye. Now Uncle Zhu can't help it. , you have to help Uncle Zhu with this no matter what.

Or, I'll try. Qin Shan is a kind-hearted girl, seeing Zhu Detai's boss pretending to be so pitiful at such a young age, she couldn't help but feel a little bit unbearable. She leaned forward and desperately searched for the English words in her stomach to communicate with the other party. When she encountered something she really didn't understand, she simply pulled a piece of paper and asked the other party to write out the words, and then dealt with the situation with guesswork.

Uncle Zhu, they said that they came from the United States, and their company name is... You see, it's this word, I don't know how to translate it, they asked you, what are the disc harrows you marked Are the performance indicators real? After listening to a paragraph, Qin Shan began to translate to Zhu Detai.

YES, YES, what...Xiao Qin, tell them that these indicators of ours are true and correct. We have conducted repeated tests in China. The performance is stable, the quality is reliable, and we implement three guarantees... Zhu Detai I couldn't help but recite the slogan in the factory.

After hearing this, Qin Shan frowned, then turned around and explained to the other party. The other party also knows that the English level of the Chinese is not high, so they are not very picky. They nodded as they listened, and from time to time helped Qin Shan correct her vocabulary and grammar, which was equivalent to being a free English teacher for Qin Shan.

After finally dismissing this group, before Zhu Detai could say a word of thanks to Qin Shan, another factory manager over there rushed over again, grabbed Qin Shan's hand, and shouted: Little Qin Shan Ah, hurry up and help Uncle, Uncle is in a hurry...

Qin Shan didn't know whether to laugh or cry, and quickly responded, Uncle Zhang, don't worry, I'll come right away. Uncle Zhu, I'll go first.

Hey, Xiao Qin, don't leave, I... oh, Lao Zhang, how dare you rob me! Zhu Detai jumped and scolded angrily.
