Tang Shu directly brought the military out for suppression, and explained the characteristics of polyurethane material clearly and clearly. Everyone present was knowledgeable, and it was obvious that the boy in front of him was definitely not a stickman who didn't know anything.

Factory Director He first glanced back and told all the technicians to shut up for the time being. Then he turned to Tang Shu with an embarrassed look on his face: "Everyone is responsible for the rise and fall of the country. Since the military region has found us, of course we are duty-bound, but in some cases

We have to make it clear in advance to avoid failure of the mission and placing all the responsibility on our factory."

"This little brother looks young, but we can tell that you have a certain understanding of the material polyurethane. Have you ever seen the entire production process?"

Tang Shu nodded: "If I am not completely sure, the military region will not let me come over to assist your factory in producing shoe sole samples."

"Ah, what a loud tone." Someone behind the factory director murmured softly. Several technicians looked at Tang Shu with disdain and contempt in their eyes. Those of them who had studied chemistry for several years and worked in this industry for several years were all shocked.

I don't dare to say such arrogant words. This guy looks like a college student at best, and he still helps them? I'm not afraid of Feng Da's tongue flashing.

Factory Director He also felt that this boy was a little too conceited, but due to the other party's status, he did not dare to drive Tang Shu out of the factory just like that. Instead, he turned sideways and made way to the workshop: "Then welcome

This little brother came to our factory for technical guidance."

Tang Shu was not polite and asked the factory director to lead the way. The group passed through the office building and came to the production workshop at the back. At this time, they caught up with a mine screen being demoulded and saw more than a dozen workers surrounding it.

In front of the steaming mold, four people held crowbars. Four people stood in pairs at both ends of the mold. There were also several people standing on the mold. They should be using their own weight to hold down the mold to prevent it.

The workers used excessive force while working and overturned the mold.

With the arrival of the factory director, the workers worked harder. A team leader shouted a slogan, and everyone took their positions. Four people holding crowbars inserted the sharpened end into the bottom of the mine screen along the edge of the mold.

, while pressing down on the crowbar, trying to separate the product from the mold. The other four big men used their hands with double gauze gloves to pull up the iron hooks on both sides of the mine screen, while the rest of them stepped on the mold.

More than ten people cooperated skillfully and moved neatly, almost using all their strength at the same time.

This kind of cooperation is very tacit, and it completely explains what ten times ten is greater than a hundred concerted efforts. Unfortunately, even though these workers have tried their best, the mine screen and the mold are still very tightly fitted together.

, there is absolutely no intention to separate.

Even though it is only late spring and the temperature in Jiangcheng is around ten degrees, the atmosphere in the workshop of the polyurethane products factory is still very hot and anxious. Perhaps this is not because the products need to be heated during the production process, but because it cannot be done smoothly.

The trouble caused by demoulding.

More than a dozen big men tried for five minutes, but to no avail. In desperation, the team leader asked everyone to rest for a while and gave up the position next to the oven. The factory director and technicians ran over to check, and surprisingly found that the iron hooks in the mine screen were combined with polyurethane materials.

There have been tears in places.

Even if such a product is pulled out, it will still be a defective product with substandard quality.

"How many times have I said that the mold must be in the oven for sufficient time, and the temperature needs to be lowered before the demoulding operation can be carried out. Why can't you listen? Isn't it just a waste of time? Compared with taking out high-quality

Products, what does this loss count?”

In the silence, a co-worker spoke, his tone full of resentment and cynicism: "It takes more than two hours to make a sieve. If you can't complete the production plan during the day, you have to work overtime. The leaders ring the bell at five o'clock and leave."

, we have to continue to stay up late and fight, we are all robots in love."

"It's just that you've been working night shifts for several days this month? We're not incorrigible. You can do three shifts at least."

"What are you arguing about? You can't stop talking about it." Seeing that the leader's face was not good-looking, the workshop director immediately came over and scolded him, "Aren't you getting overtime pay for overtime work? Besides, you also know that the mine screen takes a long time to solidify in the oven.

You can definitely take advantage of this time to rest. What’s the point of being tired? You’re all contributing to the construction of society, and you’re complaining all the time?”

As the saying goes, the county magistrate is not as good as the current manager. The factory director's criticism was complained by the workers. The workshop director roared and everyone fell silent. A worker standing behind the crowd glanced at Tang Shu, who was neatly dressed, and said softly.

: "Are you planning to come as an intern? I would like to advise you, if you have anything to do with your family, hurry up and leave. The work in this factory is not done by humans."

"Li Dazui, I have to deal with you again. Go to work quickly."

While the ore screen in the mold was cooling, Director He came to Tang Shu: "Comrade Xiao Tang, you have also seen that this ore screen is 1.8 meters long and 1.2 meters wide, and the material used is about 50 kilograms.

About, it is so difficult to demould such a large sieve, and it can easily cause tearing during the process. Do you think the small sole can withstand such a tensile force?"

Director He's meaning is very obvious. The soles are too thin. If the polyurethane is not completely solidified and cooled, there is no way to pull it out of the mold. If the current production process is followed, the output of one mold in a day will only be twenty or thirty at most.

Pair, how many people are there in the entire Ningcheng Military Region? If everyone wants to have a pair of polyurethane military shoes, I'm afraid they will have to wait until the next century.

Tang Shu nodded slightly. He had long expected that this would be the case in the production of polyurethane products in this era. Because of the difficulty in demoulding, the production time was too long. The mold had to be reheated after cooling, and this process took another fifteen minutes.

, calculated in this way, it takes at least two and a half hours for a product from the beginning of casting to the final release of the mold.

Small products may take less time, but there is definitely no profit.

Therefore, the factory is naturally unwilling to leave the ore screen that requires a lot of materials and help Tang Shu make shoe soles. The cost of a mine screen is tens or even hundreds more. How much does the sole cost?

When he came to the mold that was being cooled outside the oven, Tang Shu reached out and touched it, then put it to the tip of his nose and smelled it: "The lubricant you use for demoulding is machine oil, right?"

Director He didn't talk to the technicians, but anyone with some industrial knowledge could tell. Since Tang Shu knew this business, he certainly didn't need them to explain.

Tang Shu wiped his hands dipped in black oil on the cloth on the workbench: "It's strange that the bottoms of these mine screens have black marks. Take a look, there are pits and bumps on them, like the surface of the moon. Let's take a look.

I have developed trypophobia."

He is still making trouble in the finished product area. The technicians are not doing their job. This guy is not here to help them. He is just looking for trouble, okay?

"We also know that if the engine oil is not brushed evenly, it will cause stacking, which will lead to such defects in the cured product. But now domestic polyurethane factories are of such a technical level. If you really don't like our products, go to

Do it abroad, the technology there is advanced, you can just let the military region spend foreign exchange purchases, why come here to humiliate us?"

"Comrade technician, please don't get excited." Seeing that the other party finally got to the point, Tang Shu was about to start his performance, "Do you know where our foreign counterparts are more advanced than us? Let me tell you, they produce this kind of

The product process is the same as ours, the only difference is that they use the most professional lubricating material, which is a release agent, instead of taking it for granted and replacing it with engine oil."

Professional release agent?

Director He and the technicians looked at each other in confusion. None of them could imagine the effect of this thing. They had not been arranged to go abroad for inspection, so of course they had no idea what this thing was.
