Lai Qingyuan became a small boss with a few employees working, which was completely beyond Fang Hanmin's expectations, but he felt that he was impressed by the three-day separation, not to mention that since he was transferred from the second workshop, he had not had contact with Lai Qingyuan for four or five years. , maybe they have changed their minds long ago. No matter what, Fang Hanmin always doesn't want to think about the worst.
However, Lai Qingyuan is different from other pricks. He is a born bastard. He has never wanted to work hard and do things seriously. Now that he can become a small boss, it has something to do with Fang Hanmin.
I remember that before the process transformation of the second workshop was about to be completed, in order to improve the operating skills of employees and meet the needs of the new process, Fang Hanmin required training for employees. Only employees who passed the training examination could be employed. Lai Qingyuan failed to pass the training examination and the new process was put into production. At that time, according to regulations, he naturally could not take up his post.
The training and assessment was originally in charge of Lao Wu, the technician of the second workshop. Lai Qingyuan failed the assessment and could not take up the job. The leader 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 assessment was Fang Hanmin's request.
Lai Qingyuan approached Fang Hanmin and wanted Fang Hanmin to be open to him. Of course, this request was rejected by Fang Hanmin. The two almost started fighting. Under Fang Hanmin's strong insistence, Lai Qingyuan finally relented and asked Fang Hanmin to give him a way out.
Fang Hanmin originally started from work and did not want to quarrel with anyone. Since Lai Qingyuan wanted to repent, he suggested that Lai Qingyuan use the week before the new process was officially put into production to seize the time to review the training content and give Lai Qingyuan a chance to make up the exam.
Before the make-up exam, Lai Qingyuan secretly gave Lao Wu a cigarette. Lao Wu naturally lowered his standards during the make-up exam, allowing Lai Qingyuan to successfully pass the make-up exam and get the chance to re-employ.
Through this incident, Lai Qingyuan realized that there is no benefit in going against the leader. As long as you have a good relationship with the leader, you can get advantages.
Although Lai Qingyuan passed the training re-examination, no one was willing to be in the same team as him during the formal grouping. This made Lai Qingyuan very embarrassed. He approached the workshop leader again. Technician Lao Wu could not help him this time. After dinner, Lai Qingyuan went to the workshop director Lao Yang When he visited his family, he not only spent money to buy some gifts, but also reviewed his past in front of Lao Yang, saying that he would change his past mistakes and must obey management and leadership in the future.
Lai Qingyuan used to go against the workshop leaders and would make unreasonable troubles in everything. He was the employee who gave the workshop leaders the biggest headache. Lao Yang didn't have a good impression of him, but now his attitude has changed 180 degrees. Lao Yang Yang felt incredible, "Qingyuan, what do you mean?"
"Director, I also passed the on-the-job training assessment, but when I was assigned to work, no team wanted me. Look..."
"Qingyuan, the new technology has been re-organized into groups, and free grouping is implemented. No one wants to be in the same team with you. This..., there is nothing I can do!"
"Director, I just said that from now on I will obey leadership and management. As long as I have a position, I can do whatever you ask me to do."
Lao Yang didn't care about Lai Qingyuan's gift. He thought it was commendable that Lai Qingyuan's attitude had changed so much. "Qingyuan, if you can't get a production position, you can work as a handyman in the workshop."
"Director, what does the handyman position do?"
"You are responsible for some chores in the workshop. Normally, it's basically fine. But if the workshop needs it, you have to step in and you can't just idle around like before."
Upon hearing this, Lai Qingyuan felt that being a handyman was a good job. Not only was it easy and comfortable, but no one would care about him, so he vowed: "Don't worry, director, I will do my job well and will never be idle."
In this way, Lai Qingyuan became a handyman in the workshop. However, at the beginning, he was just a polished commander. After a year or two, several employees were transferred from other positions and were also assigned to handyman positions, because Lai Qingyuan was in this position. Although the only veteran has not been formally appointed by the workshop leader, everyone still thinks that Lai Qingyuan is the person in charge of the miscellaneous positions.
Over time, Lai Qingyuan also regarded himself as a junior leader in his position. In fact, he did not enjoy the treatment of a team leader, but he did not care.
Just now I saw Fang Hanmin criticizing their work. Lai Qingyuan regarded himself as a post leader and did not take Fang Hanmin's criticism seriously. However, he finally realized that even if he was the person in charge of the miscellaneous position in the second workshop, he was just a team leader. How dare he blatantly Disobey the technical section chief's instructions?
Thinking of Lai Qingyuan's attitude towards work just now, Fang Hanmin thought that except for the way he spoke, which was not as arrogant as before, his nature had not changed much.
After listening to Fang Hanmin's evaluation of Lai Qingyuan, the two leaders of the second workshop felt that it was a bit inappropriate to leave such an important matter to Lai Qingyuan, "Then don't let Lai Qingyuan do this work, and find another employee with a strong sense of responsibility to take charge of this." thing."
Fang Hanmin took over the responsibility himself, "Actually, it's not necessary. Maybe I didn't explain the importance of this matter to the staff before. I just told a few of them that the replaced spent catalyst is not good at all." It’s a waste, let’s see what they do next.”
...
The decoration of the central laboratory is nearing completion, and the test equipment for waste catalyst recovery and treatment has been installed. Fang Hanmin has already drawn up a test plan. A few days ago, he handed the plan to his two assistants and asked them to prepare the test requirements according to the plan. of raw materials.
In mid-September, the recycling and treatment test of the spent palladium carbon catalyst officially started. The main purpose of this test is two-fold. One is to recover the precious metal palladium in the spent catalyst, and the other is to harmlessly treat the catalyst carrier.
In order to save time, Fang Hanmin divided the experiment into two parts. Guo Peng was responsible for the recovery of precious metals, and Wan Cheng was responsible for the harmless treatment of the catalyst carrier. The two parts acted separately without interfering with each other.
Because the technology given by the time traveler 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 just asked his two assistants to conduct the test step by step.
Like several previous experiments, this technology that has matured in the previous life of the time traveler was verified by two assistants and test workers in the laboratory. The main purpose was to give them a perceptual understanding of this technology and prepare for the next step. Accumulate experience in actual production.
A week later, news came from the precious metal recycling test that Guo Peng was responsible for. They obtained metal palladium in the test, but the metal was not pure enough and the recovery rate was only 60%. This only shows 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.
The harmless treatment test of the catalyst carrier that Wan Cheng was responsible for also obtained preliminary results a few days later. After testing, the remaining metals and raw materials in the treated catalyst carrier were reduced by 80% and 8% respectively. Fifteen, obviously, is just the first step in the right direction.
Because there are two assistants in charge, and Fang Hanmin has a lot of other work on hand, even though he often goes to the laboratory to understand the progress of the experiment, Fang Hanmin does not personally intervene in the experiment.
On this day, Fang Hanmin was thinking about next year's technology development project in the office. Guo Peng opened the door and came in, "Director, we have encountered a problem."
"What's going on?" Fang Hanmin motioned to Guo Peng to sit down opposite and talk.
"The purity of the precious metals now recovered has basically met the requirements, but the recovery rate has stopped at around 90%. Although the test has been repeated five or six times, there has been no significant improvement. This is still far from the requirements you put forward in the test plan. Eight percent, we can’t figure out what the problem is.”
Guo Peng introduced the test process in detail. After some analysis, Fang Hanmin asked: "Is the particle size of the carrier crushed uniform?"
"Well..., I didn't pay much attention to it, but the number of meshes in the crusher is fixed, I think it should be about the same."
"We are engaged in technical work. We should not take anything for granted. Instead, we should explain the problem through test data. If you don't believe me, go back and take a look. In addition, during the centrifugal separation process, are the centrifuge speed and time sufficient? This also needs to be answered through experiments. question."
Guo Peng nodded in agreement, "Well, we really don't pay enough attention to these aspects. In future tests, we will focus on examining the impact of these conditions on the test results."
More than a month later, the harmless treatment test of the catalyst carrier that Wan Cheng was responsible for made little progress. After learning about the situation, Fang Hanmin helped analyze the reason, "I think the particle size of the crushed carrier is still too large and is adsorbed in the porous structure. The metals and raw materials are not easy to remove.”
"Director, this is already the maximum mesh size of our crusher."
"That means the performance of this equipment does not meet the requirements. In addition, is the dipping and stirring time of the carrier enough? Have you done any comparative experiments?"
"It is easier to conduct a comparative test of immersion and stirring. If the performance of the crusher does not meet the requirements, what should we do?"
"Do a comparative experiment first. If the problem is not here, it means that the crushing particle size is not enough. You should make plans quickly and buy equipment with better performance as soon as possible."
Following Fang Hanmin's suggestion, the two assistants led their respective test teams to conduct several more tests. Guo Peng's team was the first to report the good news. They had increased the precious metal recovery rate to 98%! This result is quite good. Even in the previous life of the time traveler, the best recovery rate was only 99%. However, the advanced level of instruments and equipment in the 21st century is not comparable to that of the 1980s. ?
Not long after, Wan Cheng’s 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 metals and raw materials remaining in the carrier to one percent and zero percent respectively without changing the particle size of the carrier. Below 5.0, even if measured according to national standards, it has reached the standard of harmless treatment.
