Chapter 7 Workshop Suspicion
Yu Fan stared at the 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, pasted it on the window and looked 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 at the customer site. We have solved it many times but have not solved it. It is very strange. If we don't solve it today, The customer is about to replace our things! This is a big customer that we have worked hard for a long time!"

Cao Ben is also a senior employee of the company. He is kind-hearted and has always cooperated with Yu Fan very well. Yu Fan also thinks highly of this good-natured young man. I joined this team and have been working hard all the time. In the first two years of the company's operation, I didn't even get paid. Cao Ben used his own money to subsidize the company.Yu Fan has always been grateful in his heart, and if one day he becomes prosperous, he will definitely repay this little brother well.

The industry that Yu Fan's company is engaged in is a very unpopular industry called "metal processing aids". Antirust agent, industrial cleaning agent, etc.Although this industry is unpopular, the requirements for technical practitioners are extremely high, and it is required to be proficient in basic chemistry, basic physics, machinery, polymer materials, biology, etc.However, the industry volume of this unpopular industry is very low, unlike some industries with incomes of tens of millions.But Yu Fan resolutely chose this industry, no one knows why.

Cao Ben applied for support from Yu Fan, of course Yu Fan would not just sit idly by, and just happened to go out to get some fresh air and change his mind.

Yu Fan and Cao Ben drove to the destination, which is a large state-owned enterprise specializing in the production of parts for high-speed trains.

The factory area is very large. Yufan'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 machining production line and about 20 CNC machine tools.

The problem reflected is the machine tool for processing copper parts, which uses the newly developed environmental protection cutting fluid (a liquid that lubricates, cools, and prevents rust during mechanical processing) newly developed by Guanghan Hengrun Chemical Co., Ltd.

Before Yu Fan and Cao Ben approached the machine tool, a master worker came over and yelled: "Xiao Cao, I asked you to bring an expert to solve our problems. What did you bring? So young? If you can't solve it, your company will leave."

Yu Fan took a look at this irritable worker master, about 55 years old, with phoenix eyes, gutter nose, narrow seal, and a typical aggressive personality.

Cao Ben was not convinced, and was about to retort, but Yu Fan stopped him and said: "The workshop is noisy, and people's voices are naturally louder, and the masters in the workshop are all in good health all year round, so they will naturally speak more confidently." Let your feet be a little louder, and your voice should be louder. However, I don’t know your surname for these masters? Who are you?”

The master's attitude eased a little, and he said: "My surname is Shi, and I am the workshop director. Look at what your cutting fluid has done to our workpieces? We process copper parts. After using up your After the cutting fluid, it was fine at the beginning, but after a few days, white hairs appeared on it, what’s the matter? It’s still like this after solving it several times.”

Yu Fan went to the machine tool to observe for a while, went to the water tank to measure the pH value, then observed the newly processed parts, and observed the parts with white hair.

Think for a moment.

He asked Director Shi again: "After the processing is finished, is there any other process?"

Director Shi was impatient: "There is no process, just put the air gun to dry it, and the white hair will grow after 3 days."

Yu Fan squinted his eyes and smiled slightly, and said: "Director Shi, you should take care of your business first, we will study it later, and we will tell you the result later."

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

Director Shi left angrily.

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

Yu Fan said: "I found the reason," but sighed again, "But this is also the problem I don't want to solve."

Cao Ben wondered: "Why? Is there any serious problem with the product?"

Yu Fan took a deep breath, closed his eyes, and said:
"No, there's nothing wrong with the product. It's about the people."
