Cao Ben paused for a moment: "What does it mean to be old?" You mean I have a problem? ”

Yu Fan was happy: "My old Tie, what is wrong with you, I'm talking about Director Shi." ”

Cao Ben was even more puzzled, what does this mean?

Yu Fan looked at Cao Ben with a weird smile and said: "Believe it or not, we are walking out of the workshop now, Director Shi is waiting for us, we have to hurry up, he is estimated to be smoking outside the workshop, after smoking, he is estimated to be leaving, we can't let Director Shi wait stupidly." He has something to say. ”

Cao Ben suspiciously followed Yu Fan outside the workshop.

When I walked out of the workshop, I saw Director Shi smoking under a tree not far away. The cigarette smoked very slowly, not burning much, it seems that Director Shi did not inhale hard, but just let it burn naturally, this cigarette seems to be a piece of incense, and this incense touches an anxious soul.

Director Shi spoke first: "Have you finished reading?" What do you think? Is there any countermeasure? ”

Yu Fan: "Actually, the reason for the problem, Director Shi, you yourself have so many years of experience, you should know better than us, right?" ”

Director Shi was stunned for a moment, quickly took a puff of cigarette, and looked around left and right.

Yu Fan said again: "It's too noisy here, let's take a step to talk." ”

Director Shi nodded, and took Yu Fan and Cao Ben to an empty playground at the end of the factory. Not a single one.

Director Shi said: "No matter what method you use, solve the problem for me, otherwise I really don't dare to use your products anymore."

Yu Fan nodded: "The problem must be solved." I checked the use status of the cutting fluid, and everything was normal in use, and I checked the PH value, which is also a weak alkali type. The copper parts are bisexual metals, and they will be corroded in a strong alkali and strong acid environment, but obviously our PH value is within the normal range, and there is a copper sustained-release agent in our cutting fluid, and the copper sustained-release agent is in an unexpired state, so the white hair on the copper is not a corrosion product, nor is it a related complex produced by the corrosion reaction. ”

Yu Fan paused. "And according to your description, the workpiece steel came out without any problems, and the problem only appeared after a few days of placement. Then the problem should be in the middle link, if my inference is correct, it is the inconspicuous blowing and drying process in the middle! The industrial high-pressure gas in the factory should be pure, and there should be a water and gas separation device. But I just tried your blowgun, and there was a lot of water in it, and there was a black solid. If nothing else, your high-pressure blow-dry air compression system is out of order, and there's a lot of moisture mixed in there, and there's internal rust, and the black solid is ferric oxide or iron hydroxide. “

Director Shi was silent. I finished smoking the cigarette just now, and I took out the cigarette case from my pocket, but the cigarette case was gone. Seeing this, Cao Ben handed over a cigarette of his own.

Yu Fan said: "Therefore, the white hair on the final copper piece should be dried with the sodium carbonate scale remaining in the drying process, as well as the complex formed by the iron hydroxide and the copper surface to solidify. But what I find strange is that you, as a senior front-line worker in the workshop for many years, don't you know that your own equipment has a problem? Why do we say again and again that it is our cutting fluid problem? Repeatedly, let's figure it out? I think there's a story in there. ”

Director Shi took another deep puff of his cigarette.

Yu Fan said again: "Director Shi, your eyeballs are full of bloodshots, your eye circles are black, and you just walked with your shoulders drooping, these are all characteristics of poor rest recently. And I have observed that many machine tools in the workshop are down, and the workload of the factory is not saturated, so the reason for your poor rest should not be work, right? In addition, you don't usually smoke much, but you have suddenly smoked more recently, you must have encountered troubles, right? ”

Director Shi's face was full of doubts: "Why do you say that I don't usually smoke?" Did we know each other before? ”

Yu Fan: "You smoked one cigarette after another just now, and the empty cigarette case you just took out is also new, so it can be seen that you didn't buy this pack of cigarettes for a long time before you finished smoking." If there are no obvious smoke marks between your fingers and no smoke stain on your teeth, it is obvious that you did not smoke much before, or you are not as good a smoker as you have been in recent days. You are about 55 years old this year, it is the time when men are most stressed, the old and the young, I think you have encountered something at home, right? ”

Director Shi made an iron face: "When it comes to this, I'll just say it, doing business in our state-owned enterprises, don't think that the product is good, you will definitely be able to sit in, without us to help you, you will not be long, the relationship is very important, relationship, do you understand?" ”

Yu Fan also smiled seriously: "I understand the truth, but I was really surprised to say it from your mouth." ”

Director Shi finished smoking again, asked Cao Ben for another cigarette, and said: "Young man, when you reach my age, you will naturally understand many things, and I am also forced to do many things, so let's put it this way, you raise the price of your cutting fluid by 10%, I will take the extra price, and I will convert the extra tickets to you, I will convert them into taxes for you, and I will not let you lose a penny, I will help you maintain the on-site work well, and there will be no more product problems." ”

Cao Ben said a little unhappily next to him: "Then what do you think of it, let me run so many times back and forth in vain!" ”

Director Shi took another deep puff of cigarette and said, "Xiao Cao, I'm sorry, in fact, this is the first time I have asked for money from a supplier for so many years, and I am really sorry for tossing you so many times before." I'm also conflicted inside. My old mother has always been in poor health and often goes to the hospital, so in order to take care of the elderly, I asked my wife not to go to work and take care of her full-time at home. I thought that as long as I worked hard, I could support this family. I work hard, work honestly, and have a good life. But recently there was a big incident in the family, my son was diagnosed with leukemia, this is a thunderstorm, we are also old, my son just went to college this year, his studies have been great, I really need money now! I want money to save my life! “

Director Shi smoked another cigarette, Cao Ben gave him another cigarette, Director Shi lit the lighter for a long time this time, but the lighter stopped burning, as if God was trying his best to get along with this middle-aged man. Cao Ben used his own lighter to light it for him again.

Director Shi's eyes were red: "This model of leukemia is relatively light, and it was discovered early, I sent him to the best hospital in the city, but he needs regular dialysis, our factory organized people to donate blood and platelets to our family, but it is still not enough, and now I only have to spend money to buy blood." There are so many expensive chemotherapy drugs that I really can't afford!! My son is still young! ”

Yu Fan looked up at the sky, as if he was, why is fate always so tricky, torturing an old man who is filial and diligent?

But Yu Fan said: "Director Shi, I'm sorry, we won't make a matter of principle, I'd rather you don't use our things, and I won't bribe you." We still can't solve your problem. ”

Yu Fan took two steps back and half-bowed to leave, as if he felt deep sympathy for the plight of a poor middle-aged man.
