Lai Qingyuan became a small leader with a few employees to work, which was completely unexpected by Fang Hanren, but he felt that Shibei should be impressed for three days, not to mention that since he was transferred from the second workshop, he had not been in contact with Lai Qingyuan for four or five years, maybe people had already changed their minds. In any case, Fang Hanmin is always reluctant to think about things in the worst way.

However, Lai Qingyuan is different from ordinary thorns, he was born a bastard, he never wanted to work hard and work seriously, and now he can become a small leader, which has something to do with Fang Hanmin.

Remember that before the completion of the process transformation of the second workshop, in order to improve the operational skills of the workers and meet the needs of the new process, Fang Hanmin asked for training for the employees, only the employees who passed the training examination can take up their posts, Lai Qingyuan just failed to pass the training examination, when the new process was put into production, he naturally could not take up the post according to the regulations.

The training assessment was originally in charge of Lao Wu, a technician in the second workshop, and Lai Qingyuan failed to pass the assessment and could not take up his post, and the leaders of the second workshop should have explained to him, but Lao Wu was afraid of offending Lai Qingyuan, so he pushed him to Fang Hanmin, because the training and assessment was Fang Hanmin's request.

Lai Qingyuan found Fang Hanmin and wanted Fang Hanmin to open up to him, of course this request was rejected by Fang Hanmin, and the two almost started fighting, but under Fang Hanmin's strong insistence, Lai Qingyuan finally relented and asked Fang Hanmin to give him a way out.

Since Lai Qingyuan has the intention of repenting, he suggested that Lai Qingyuan use the new process to review the training content a week before it is officially put into production, and give Lai Qingyuan a chance to make up the exam.

Before the make-up examination, Lai Qingyuan gave Lao Wu a cigarette behind his back, and Lao Wu naturally lowered his standards during the make-up examination, so that Lai Qingyuan successfully passed the make-up examination and got the opportunity to re-work.

Through this incident, Lai Qingyuan realized a truth, there is no benefit in going against the leader, as long as you have a good relationship with the leader, you can get cheap.

Although Lai Qingyuan passed the training make-up examination, but in the formal grouping, no one wanted to be with him a team, which made Lai Qingyuan very embarrassed, he found the workshop leader again, the technician Lao Wu could not help him this time, after dinner Lai Qingyuan went to the workshop director Lao Yang's house, not only spent money to buy some gifts, but also reviewed his past in front of Lao Yang, said that he would change his past wrongs, and he would obey the management and obey the leadership in the future.

Lai Qingyuan used to fight against the workshop leaders, and everything had to be unreasonable, he was the most headache for the workshop leaders, Lao Yang didn't have a good impression of him, and now his attitude has changed one hundred and eighty degrees, Lao Yang felt incredible, "Qingyuan, what do you mean?" ”

"Director, I have also passed the job training assessment, but when I go to the post group, I don't want any team, you see ......"

"Qingyuan, the new process is back in the group, the implementation of free combination, no one wants to be in the same team with you, this ......, I can't help it!"

"Director, as I said just now, I will obey the leadership and management in the future, as long as there is a position, you can let me do anything."

Lao Yang didn't care about Lai Qingyuan's gift, he thought that Lai Qingyuan's attitude could change so much, it was really commendable, "Qingyuan, if you can't get to the production position, you can go to the workshop to work in the miscellaneous position." ”

"Director, what is the miscellaneous position for?"

"It's just responsible for some chores in the workshop, and it's basically fine, but once the workshop is in need, you have to go up, and you can't hang up like before."

When Lai Qingyuan heard this, he felt that being a handyman was a good errand, not only was it easy, but no one cared about him, so he swore and promised: "Director, don't worry, I will do a good job, and I will never be a child." ”

In this way, Lai Qingyuan became a handyman in the workshop, but at the beginning, he was just a light commander, and after a year or two, several employees were transferred from other positions, and they were also arranged in the handyman position, because Lai Qingyuan was the only veteran of this position, although he was not officially appointed by the workshop leader, everyone still thought that Lai Qingyuan was the person in charge of the miscellaneous post.

After a long time, Lai Qingyuan also regarded himself as a small leader in his position, in fact, he did not enjoy the treatment of the team leader, but he didn't care.

I saw Fang Hanmin criticizing their work just now, Lai Qingyuan regarded himself as the leader of the post, and he didn't think much of Fang Hanmin's criticism, but he finally realized that even if he was the person in charge of the miscellaneous post in the second workshop, he was just a team leader, how could he dare to blatantly disobey the instructions of the technical section chief?

Thinking of Lai Qingyuan's attitude towards work just now, Fang Hanmin thought that this guy's essence had not changed much except that his way of speaking was not as arrogant as before.

After listening to Fang Hanmin's evaluation of Lai Qingyuan, the two leaders of the second workshop felt that it was a bit improper to hand over such an important matter to Lai Qingyuan, "Then don't let Lai Qingyuan do this work, and find a new employee with a strong sense of responsibility to take care of this matter." ”

Fang Hanmin took the responsibility himself, "Actually, there is no need, maybe I didn't explain the importance of this matter to the employees who worked clearly, I told them just now, the replaced waste catalyst can't be wasted at all, see what they do in the future." ”

......

The decoration of the central laboratory is nearing completion, the test equipment for the recovery and treatment of waste catalysts has been installed, Fang Hanmin has already drawn up a set of test plans, and he handed over the plans to two assistants a few days ago, so that they can prepare the raw materials required for the test according to the plan.

In mid-September, the recovery and treatment test of waste palladium carbon catalyst officially began, and the main purpose of this test is twofold, one is to recover the precious metal palladium in the waste catalyst, and the other is to harmless the catalyst carrier.

In order to save time, Fang Hanmin divided the test into two parts, Guo Peng was responsible for the recovery of precious metals, and Wancheng was responsible for the harmless treatment of the catalyst carrier.

Because the technology given by the traverser in the test plan has been very mature in the 21st century, whether it is the recovery of precious metals or the harmless treatment of catalyst carriers, Fang Hanmin asked the two assistants to conduct the test step by step.

As with the previous experiments, this technology, which had matured in the previous life of the traverser, was verified by two assistants and test workers in the laboratory, and its main purpose was to give them a perceptual understanding of this technology and accumulate experience for the subsequent actual production.

A week later, Guo Peng's precious metal recovery test came with the news that they had obtained palladium metal, but the purity of the metal was not enough, and the recovery rate was only 60%. This can only show that Guo Peng's test team has opened up the recycling process, and there is still a lot of work to be done before the test is successful.

Wancheng was responsible for the harmless treatment of the catalyst carrier, and the preliminary results were also obtained a few days later, after testing, the residual metals and raw materials of the treated catalyst carrier were reduced by 80% and 85% respectively, obviously, this is only the first step in the right direction.

Because there are two assistants in charge, and Fang Hanmin has a lot of other work at hand, even if he often goes to the laboratory to learn about the progress of the test, Fang Hanmin does not personally interfere in the test.

On this day, Fang Hanmin was in the office thinking about next year's technology development project, when Guo Peng pushed the door in, "Director, we have encountered a little problem. ”

"What's the situation?" Fang Hanmin motioned for Guo Peng to sit down and speak opposite.

"Now the purity of the recovered precious metals has basically reached the requirements, but the recovery rate has stopped at about 90 percent, although the test has been repeated five or six times, but there is no obvious improvement, which is eight percent away from the requirements you put forward in the test plan, we can't think of what the problem is."

Guo Peng introduced the test process in detail, and through some analysis, Fang Hanmin asked: "Is the particle size of the carrier crushed uniform?" ”

"I didn't pay much attention to this ......, but the number of meshes of the shredder is fixed, so I think it should be about the same."

"We are engaged in technical work, and we can't take everything for granted, but we should explain the problem through test data, and I don't believe you can go back and take a look. Also, is the speed and time of the centrifuge sufficient during centrifugation? This is also a question that can only be answered through experimentation. ”

Guo Peng nodded in agreement, "Well, we really don't pay enough attention to these aspects, and in future experiments, we will focus on the impact of these conditions on the test results." ”

More than a month has passed, Wan Cheng is responsible for the catalyst carrier harmless treatment test has not made much progress, after learning about the situation, Fang Hanmin helped analyze the reason, "I think the crushed carrier, the particle size is still too large, adsorbed in the porous structure of the metal and raw materials, not easy to remove." ”

"Director, this is already the maximum number of meshes of our crusher."

"That means the performance of the device is not up to the mark. In addition, is the impregnation stirring time of the carrier enough? Have you done any comparative experiments? ”

"The comparative test of impregnation and mixing is easier to do, if the performance of the pulverizer does not meet the requirements, what should we do?"

"Do a comparative experiment first, if the problem is not here, that is, the crushing particle size is not enough, you hurry up and make a plan to buy equipment with better performance as soon as possible."

According to Fang Hanmin's suggestion, the two assistants took their respective test teams to conduct several more tests, and Guo Peng's team was the first to spread the good news, they increased the recovery rate of precious metals to 98%! This result is quite good, even in the previous life in which the traverser lived, the best recovery rate was only 99 percent, but the 21st century equipment is more advanced than it was in the 1980s.

Soon after, the Wancheng team also came up with the test results. After comparative experiments, they optimized the impregnation and stirring conditions of the carrier, and reduced the content of metal and raw materials remaining in the carrier to less than 1% and 0.5% respectively without changing the particle size of the carrier, which reached the harmless treatment standard even if measured according to the national standard.
