Although Deputy Factory Director Wang tried his best to avoid interacting with Fang Hanmin, he could not refuse Fang Hanmin's warm invitation. After all, he was here to understand the test run of the new process, and Fang Hanmin was the commander-in-chief of process transformation.

If he categorically rejects Fang Hanmin's kindness, it will not only appear to be too stingy, but also lose his identity.

Despite this, Lao Wang also wanted to shorten the time he spent alone with Fang Hanmin as much as possible. He told Fang Hanmin that because time did not allow, he only wanted to visit a few important positions.

Fang Hanmin took Lao Wang to inspect the condensation, refining and crystallization stations of the three production units, and introduced him to the difference between the old and new processes and the characteristics of the new process. Lao Wang just nodded slightly and did not ask any questions. Did Fang Hanmin listen?

Introduction, only he knows.

After leaving the crystallization post of the fifth production unit, Lao Wang said: "I still have something to do, I will learn more about it later." and left in a hurry.

Watching Lao Wang leave, Fang Hanmin shook his head. Birds of a feather flock together, and this is true. It seems that it is not easy to resolve the old feud with Lao Wang!

Just as Fang Hanmin was about to turn around to inspect various posts, he saw Chief Engineer Lao Xia walking into the workshop door. He greeted him from afar, "Mr. Xia, why are you here?"

"I heard that the new process test run in the first workshop was successfully put into production. I came to take a look and learn about the production situation."

"Okay, welcome to Mr. Xia's inspection work! I'm about to go to each post to inspect, let me accompany you to inspect?"

"Do you have time? If you have time, you might as well come with me."

"Let's go. If you have time, you should accompany the leader to inspect the work."

"After all, you are the commander-in-chief. With you here, I can ask you at any time if I don't understand something."

"Mr. Xia, do you want to visit every position, or select important positions?" Fang Hanmin also asked.

"How long will it take to read it from beginning to end?"

"If you just take a quick look at it, you will be able to read it almost before you get off work. If you have to look carefully, half a day is not enough."

"Oh, let's take a selective look."

Fang Hanmin took Lao Xia around more than ten positions. Unlike Lao Wang, every time he arrived at a position, Lao Xia not only listened carefully to Fang Hanmin's introduction, but also took the initiative to ask some interesting questions.

In the condensation position, Lao Xia analyzed and compared the process conditions such as time and temperature of the new and old processes. "Although there is not much difference between the two, the by-product acid gas is gone, which plays a key role in eliminating pollution."

"Because the new process uses a different process route and replaces two raw materials, it completely eliminates the pollution of equipment and environment by acid gas. In addition, the use of this new condensation reactor not only makes the reaction process easier to control, but also eliminates the need for

risk factors, and the selectivity and yield have been improved to varying degrees." Fang Hanmin explained.

"Oh, how much improvement have these two indicators compared with the old technology?" Lao Xia seemed to be more interested in this.

"The selectivity increased by 10 percent, and the yield increased by 6 percent."

"This is of great benefit to reducing production costs, and the new technology is indeed effective!" Lao Xia said sincerely.

"Isn't this the purpose of process transformation? It is also the result of technological progress." Fang Hanmin said with a kind of confidence.

When they arrived at the product refining station, the workers were busy. Fang Hanmin introduced the specific operation process to Lao Xia, "Because the conversion rate of raw materials has increased, the new process has shortened the time in the product refining stage by one-third."

"This means that production efficiency will also increase by 30%, right?" Although the specific content of the new process is not yet clear, chief engineer Lao Xia is still quite familiar with the general technical process.

"Yes, on the premise of ensuring selectivity, after the raw material conversion rate is increased, it not only shortens the product refining time, but also improves production efficiency and equipment utilization."

"So, the production of sulfonamide drugs in the first workshop can be expanded?"

"If we follow this production efficiency and the scale of the existing equipment, under full load operation, the output of the first workshop can be increased by at least 20%. But Mr. Xia, you also know that the market for sulfa drugs is only that big.

According to the development trend, this type of drugs has almost no potential to be tapped in the future. Under the squeeze of new drugs with better efficacy and smaller side effects, their market space will become smaller and smaller. Therefore, equipment production capacity is one thing

, the product market is another matter.”

Fang Hanmin said it more euphemistically, but the meaning was very clear, that is, the output should be determined according to the market. The market for sulfonamide drugs will gradually shrink. Even if the equipment production capacity allows, production cannot be expanded blindly.

On this issue, Lao Xia didn't seem to agree with Fang Hanmin's point of view, "Are you saying that sulfa drugs are about to become obsolete? Is it just your imagination, or is there any evidence?"

"At the National Pharmaceutical Science and Technology Seminar in May, experts were almost unanimously not optimistic about the future of sulfa drugs. It is not that this type of drug will become obsolete soon, but that its clinical application prospects are not very bright because of the replacement

Its high-efficiency and low-toxic drugs are being developed and are progressing smoothly, and will be used in clinical trials in about three to five years."

In fact, this is completely Fang Hanmin’s own opinion, because at the National Pharmaceutical Technology Symposium in May, no expert mentioned the future of sulfa drugs. However, the time traveler is a doctor of pharmaceutical sciences from Oxford University from the 21st century

, he knew that sulfonamide antibiotics, which have serious side effects, would be replaced by other antibiotics with high efficiency and low toxicity within a few years.

Although Lao Xia is the chief engineer of the Red Star Pharmaceutical Factory, in a local state-owned enterprise of this size, the position of chief engineer has actually become an administrative position, because he neither pays attention to new technologies or products, nor does he hardly follow

The outside world engages in technical exchanges, let alone technology research and development. The chief engineer's function is only to manage the existing technology in the factory. Therefore, Lao Xia is skeptical of Fang Hanmin's views.

Fang Hanmin knew that his point of view could not convince Lao Xia, so he brought out the expert opinions from the National Pharmaceutical Technology Seminar in May. People like Lao Xia have always been more superstitious about authority. When he heard that the experts thought so, he actually believed it.

"Sulfa drugs are outdated, what should Red Star Pharmaceuticals do?"

“Mr.

Secondly, even if products that replace sulfonamide antibacterial drugs are used in clinical practice, it is impossible to completely replace them overnight, so there must be a step-by-step process; thirdly,

,Although sulfa antibiotics have many shortcomings in clinical application, they are still indispensable in some special fields."

Lao Xia nodded, "In other words, this drug will not be discontinued all of a sudden."

"In the foreseeable future, it is impossible to suspend production. What I want to explain is that because its market space is getting smaller and smaller, even if the equipment production capacity of the first workshop is OK, there is no need for the Red Star Pharmaceutical Factory to expand production."

Because this brought up an additional topic, Fang Hanmin and Lao Xia stayed at the product refining station for more than half an hour, "Mr. Xia, do you want to go look elsewhere?"

Lao Xia looked at his watch and said, "There's still one hour before I get off work, so I can go to another job."

The two came to the crystallization post. Fang Hanmin introduced the process conditions and operating procedures to Lao Xia as usual. "This post has the same role in the new and old processes, but the size of the crystallization particles is different."

"Oh, will it affect product quality?" Lao Xia immediately became alert.

"It has been tested many times and has no impact on product quality."

"Have you done any analysis to find out what causes the change in crystal particle size?"

"Obviously, because the raw material routes are different, the condensation reaction mechanism has changed, which affects the crystallization speed and ultimately leads to differences in the size of the crystal particles."

"As long as the purity of the product does not change, the size of the crystal particles is not a problem, because users have to crush it during use."

"In fact, because the crystal particles obtained by the new process are smaller, the impurities contained in the crystals are relatively small. Through multiple test comparisons, the current product content has been slightly improved."

"Well, it makes sense. The larger the crystal particles are, the more likely they are to contain impurities."

...

Three days later, Fang Hanmin came to Factory Director Yuan's office and reported to him on the process transformation of the first workshop. "We haven't written any written materials yet. Let's make an oral report first."

"Don't worry about the written materials. Just briefly describe the process and then explain the results in detail." Director Yuan always understood this young man very well.

After listening to Fang Hanmin's report, Lao Yuan was very satisfied with the results, "The process transformation was very successful. This is the role of technological progress. Therefore, Red Star Pharmaceutical Factory must unswervingly implement the previously formulated scientific and technological progress plan."

"Now that the Technical Section's work in the first workshop has been completed, it stands to reason that our people should be withdrawn, but..."

"The work you are responsible for has been completed. Of course, the people from the technical department should be withdrawn. Otherwise, the leaders of the first workshop will not be able to work. Why, are there any other problems?" Seeing that Fang Hanmin had not finished speaking, Lao Yuan asked.

"I'm worried about whether the two leaders of the first workshop can effectively manage production after the people in the technical department evacuate." Fang Hanmin said in a low voice.

"The two leaders of the second workshop were able to take over management after you withdrew. Why can't the first workshop be the same?"

"Director Yuan, the specific situation is different! When we were engaged in process transformation in the second workshop, their workshop director and technicians followed closely throughout the process. In the end, they were very familiar with the operating essentials and precautions of each position. The two people in the first workshop

The leaders, especially their Director Su, sit in the office every day and are basically indifferent to the situation in the workshop. I feel that he does not fully understand the new process."

"So that's it! Are you worried that Lao Su has not mastered the new technology and that he will make mistakes in management?"

Fang Hanmin nodded and said nothing.

"But this is just your worry. What if Lao Su is learning in secret and deliberately doesn't let you know. In fact, he already knows the new technology very well. Is it possible?" Lao Yuan is the director of the factory and has rich experience. He considered

Question is more cautious than Fang Hanmin.

Although Fang Hanmin did not believe that Su Wenquan would secretly learn new techniques, he could not deny the hypothesis put forward by Factory Director Yuan. After all, his worry was also an unfounded guess.

"Maybe, Director Su is an old leader in the factory, he should have enough consciousness." Fang Hanmin said bitterly.

One day later, after explaining some precautions to the two leaders of the first workshop, Fang Hanmin and his two assistants all withdrew from the technical department. He asked Jiang Guoxin and Xu Hui to sit in the office and prepare a written report on the process transformation of the first workshop.

For this technical transformation, the two assistants have been busy for three or four months. Unlike Fang Hanmin, they are both people with families. They spend a long time at the construction site. Not only are they tired, but they also rarely take care of their families, which makes Fang Hanmin
Chapter completed!
