Yu Fan looked at this photo in a daze, the seemingly chaotic paper symbols seemed to have their own rules. This pattern seems to have been seen somewhere.

Yu Fan printed out the photo and pasted it on the window to look at it carefully.

At this time, Cao Ben knocked on the door of Yu Fan's office, and hurriedly said to Fan: "Mr. Yu, there is an abnormal phenomenon on the customer's site, we have solved it many times and have not solved it, it is very strange, if we don't solve it today, the customer will replace our things!" This is a big customer that we have worked hard for a long time to conquer! ”

Cao Ben is also a veteran employee of the company, with a good nature, has always cooperated with Yu Fan tacit understanding, Yu Fan also attaches great importance to this young man with good conduct, when Yu Fan just came to XA City to develop a new company, Cao Ben joined the team, has been hard work, the first two years of the company's operation did not even have a salary, Cao Ben used his own money to subsidize the company. Yu Fan has always been grateful in his heart, and if he soars one day in the future, he will definitely repay this little brother.

Yu Fan's company is engaged in a very unpopular industry, called "metal processing aids", mainly to provide machinery factories with lubrication, rust prevention, cleaning chemicals in the processing process, such as cutting fluids, lubricants, rust inhibitors, industrial cleaning agents and so on. Although this industry is unpopular, the requirements for technical practitioners are extremely high, requiring proficiency in basic chemistry, basic physics, machinery, polymer materials, biology and so on. However, the industry volume of this unpopular industry is very low, unlike some industries with tens of millions of revenues. But Yu Fan resolutely chose this industry, and no one knows why.

Cao Ben asked Yu Fan for support, but of course Yu Fan would not sit idly by, and just went out to breathe and change his thinking.

Yu Fan and Cao Ben drove to their destination, a large state-owned enterprise that specializes in producing parts for high-speed rail trains.

The factory area is very large, and Yu Fan's products have just been squeezed into their factory and are currently being used in a workshop.

Yu Fan and Cao Ben entered the workshop, which has a complete set of machining production lines and about 20 CNC machine tools.

The problem is that the machine tool used to process the copper parts uses our new environmentally friendly cutting fluid (a liquid that lubricates, cools and prevents rust during machining).

Yu Fan and Cao Ben hadn't yet approached the machine tool, and a worker master came over next to him and scolded directly: "Xiao Cao, I asked you to bring an expert over to solve the problem for us, what did you bring?" So young? If it doesn't work out today, your company will get out. ”

Yu Fan looked at this irascible worker, about 55 years old, with phoenix eyes, a gutter nose, and a narrow Yintang, typical of an aggressive personality.

Cao Ben was not convinced, and was just about to return the favor, but Yu Fan pulled it and said: "The workshop is noisy, and the sound of people talking is naturally loud. However, I don't know your surname for these masters? Who are you? ”

The master's attitude also eased a little, and said: "Don't give your surname Shi, I am the workshop director." Do you see what your cutting fluid has made our workpieces look like? We are processing copper parts, after using up your cutting fluid, it was fine at first, but after a few days, it was white hair, what happened? Solved it several times. ”

Yu Fan walked to the machine tool and observed for a while, measured the PH value in the interesting water tank, and then observed the parts that had just been processed, and then observed the parts with long white hairs.

Ponder for a moment.

He asked Director Shi again: "After processing, what are the other processes?" ”

Director Shi was impatient: "There is no process, the air gun is dried and placed there, and it will grow white hair after 3 days." ”

Yu Fan squinted his eyes and smiled slightly, and said, "Director Shi, you are busy with your affairs first, we are studying it, and we will tell you the results later." ”

Director Shi: "Okay, you can show me carefully, are young people reliable?" ”

Director Shi left stupidly.

Cao Ben hurried over and asked anxiously: "Old Yu, have you found the cause of the problem?" What's going on? ”

Yu Fan said, "The reason has been found," but sighed again, "But this is also the last thing I want to solve." ”

Cao Ben was puzzled: "Why?" Is there anything serious wrong with the product in addition to? ”

Yu Fan took a deep breath, closed his eyes, and said:

"No, there is no problem with the product. It's a human problem. “
