"Can I try this blade?" Hibbs could no longer pretend to be reserved and asked Qin Hai impatiently.
Qin Hai smiled and said: "Please do it, but you have to be small..."
Before he could say the word "heart", a flash of red appeared on Hibbs's finger. This unbelieving guy actually tried the edge of the rake blade with his hand, and it was cut cleanly.
A gash was opened.
"This is impossible!" Hibbs yelled out of control, "How did you solve the problem of ceramic sharpening!"
Everyone knows that ceramics are a highly wear-resistant material, and Tolfson also has a team that is working hard to solve the problem of sharpening ceramic basic parts. Or to be more precise, it is to study how to ensure strength while maintaining strength.
Make ceramicware thinner.
Ceramics are fired from porcelain clay. The porcelain clay itself does not have very strong viscosity. If it is made too thin, it will be easily damaged. In order to improve the viscosity of the porcelain clay, ceramicists try to mix colloids into the porcelain clay to make the porcelain clay
It turns into a sticky clay, and then is extruded or forged into thinner utensils.
After the utensils are formed, they must be fired, which is an indispensable process for ceramic production. During the sintering process, the colloid in the porcelain clay will evaporate due to high temperature, leaving only the porcelain clay that will be transformed into ceramics in the kiln. The problem arises
In the process of evaporation of colloids, countless tiny holes will be left in the clay after these colloids evaporate, which will reduce the strength of ceramic products and may even leave hidden dangers of foreign matter penetrating.
Unable to solve the above technical problems, Tolfson's engineers have never been able to make ceramic rake blades thin enough, let alone sharpen the ceramic rake blades. However, the ceramic rake blades Qin Hai took out
But it is a real cutting edge, and Hibbs proved several points with the price of blood: first, the blade is thin enough; second, the surface of the blade is very smooth; third, the material is dense enough, Hibbs
Not a trace of the blood on the hands penetrated into the ceramic. As can be seen from the last two items, the Chinese have solved the problem of tiny holes after the gel evaporates.
This disc rake is a new product developed by Qin Hai under the guidance of Quwu Brothers Ceramics Factory. Its porcelain clay uses nano-scale zirconia powder, and a special gel is added for compaction processing. Using this
The gel, coupled with a special sintering process, can ensure that the body shrinks when the gel evaporates, thereby eliminating the holes in 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 rake blades. In fact, using nano-scale zirconia materials to make disc rake blades is really too extravagant. Qin Hai's goal is,
It is a very popular household item in later generations - ceramic knife.
The hardness of zirconia ceramic knives is second only to diamond. When used in a home environment, it can almost never wear out. It does not need to be sharpened frequently like metal knives. In addition, ceramic knives are beautiful, easy to clean, never corrode, and can cut easily.
Food does not produce the same fishy smell as ordinary metal knives, and it quickly became popular all over the world at the beginning of the 21st century.
Last time, Liu Shuo and Huang Yanling went to Qin Hai's home and expressed their hope to enter the civilian ceramic market. Qin Hai had an idea and thought of an artifact like a ceramic knife, and then guided them to create actual samples. In order to be able to use the agricultural machinery exhibition as a platform
. He specially asked Liu Shuo to make a few ceramic disc rakes. Although they were overkill, they could be used for advertising and were worth the money.
Naturally, Qin Hai would not explain too much to Hibbs about all the twists and turns. Seeing Hibbs' hands bleeding, he gloated and said "sorry", and then handed the blade to him. Ask the staff to include them in the scope of the test.
"How is this possible?" Hibbs' head was dizzy. He almost doubted what he saw, but the bloody cut on his hand reminded him that all this was true.
"Mr. Qin, is this ceramic rake blade the product you are talking about that has not been tested to the upper limit of durability?" Hibbs asked.
Qin Hai nodded and said: "Yes, because of time constraints. We were not able to complete the test of its durability limit. However, in our test, the same rake blade withstood the durability test of more than 500 hectares. Knife The body shows no significant wear and tear.”
"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 withstand 500 hectares.
"Can you tell me what kind of ceramic this rake blade is made of?" Hibbs asked again.
"It's zirconium dioxide, and there are some trace amounts." Qin Hai replied readily.
Qin Hai plans to sell ceramic knives, so the main material of the knives must not be concealed. What's more, this kind of thing cannot be concealed. Others can just buy a knife and conduct a test to analyze it. The true quality of ceramic knives The technical secret lies in the gel and sintering process used by Qin Hai. This is a problem that has taken countless people 20 years to solve. Qin Hai only crossed this technical threshold with the help of a cheating device like Time Travel.
The gel has evaporated during the sintering process, and others cannot detect its composition from the tool. The sintering process is even more deceiving. There are millions of combinations of temperature and time. Unless industrial spies can be sent to spy, Otherwise, no one can guess it out of thin air.
The durability performance test was done on the fly. After Qin Hai sent all the basic parts in, the staff started the equipment and started testing. Although the evaluation standard is the durability life of the basic parts in soil operations, the real The tests are not conducted on 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 place the basic part in a machine to rotate at high speed, and then contact it with friction material to calculate the wear speed of the basic part. This kind of test can simulate the wear and tear of the basic part in a relatively short time. The effect of farming operations on one hundred hectares, and for the sake of intuition, the final test results are also presented in terms of operating area.
The entire expo venue is large, but the social circle is very small. These agricultural machinery manufacturers have more or less connections with each other. The Chinese brought some basic parts produced with special materials and special processes, and said The news that it could surpass the world's advanced level quickly spread throughout the entire venue. As a result, before Cui Hongchun and his people could set up the booth, there was already an endless stream of people coming to visit and exchange. You know, when it really started It's tomorrow.
"Sir, how are the surfaces of your tools treated?"
"Excuse me, is this a pure ceramic knife? Oh, cake seller, how did you make the ceramic so thin?"
"Can I use it to cut paper? 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 all colors gathered around the booth of the Chinese delegation. While looking at the various basic items on the booth, they asked the Chinese people in the booth to ask questions. This embarrassed everyone.
In this group of people, in addition to translators, there are only five people who can speak English, including Ning Jing and Qin Shan, two high school students. Compared with those factory directors in their 50s, Ning Jing and Qin Shan
The two of them are simply "super good" in English.
"Little girl, please listen to me, what are they talking about?" Zhu Detai, the director of the Northern Agricultural Machinery Factory, pulled Qin Shan to his booth and pointed at the two chattering people who were talking lively.
The white man said in a pleading tone.
"Uncle Zhu, my English is not good..." Qin Shan replied in embarrassment.
Zhu Detai did not have the demeanor of an elder at all, and said shamelessly: "No matter how bad your English is, it is still much better than your Uncle Zhu... Well, if I had known this, I wouldn't have shown up like this. Now Uncle Zhu has no choice.
, you must help Uncle Zhu no matter what."
"How about I give it a try." Qin Shan is a kind-hearted girl. She couldn't bear to see Zhu Detai pretending to be so pitiful at his age. She stepped forward and searched desperately.
She used the English words in her stomach to communicate with the other party. When she really didn't understand something, she simply pulled out a piece of paper and asked the other party to write the words, and then she dealt with the situation by guessing.
"Uncle Zhu, they said that they are 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 rakes 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 been tested repeatedly in China. The performance is stable, the quality is reliable, and we implement three guarantees..." Zhu Detai
I couldn't help but recite the factory's slogan.
After listening, Qin Shan frowned and turned back to explain to the other party. The other party also knew that the Chinese people's English level was not very high and they were not very picky. They nodded while listening and helped Qin Shan correct her from time to time.
The vocabulary and grammar are equivalent to being a free English teacher for Qin Shan.
After finally getting rid of this group, before Zhu Detai could say a word of thanks to Qin Shan, another factory director over there ran over in a hurry, took Qin Shan's hand, and shouted: "Little Qin Shan, little girl"
Ah, help uncle quickly, 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 be over right now...Uncle Zhu, I'll go over first."
"Hey, Xiao Qin, don't leave, I...Oh, Lao Zhang, why are you robbing Hu!" Zhu Detai jumped angrily and cursed.
PS: I would like to recommend a friend's new work "Game Development Giant", which is about to return to 1984 and start developing games. Although it is not a work of the Industrial Party, it is still an entrepreneurial article. It is 200,000 words, not a seedling. If you are interested
