Chapter 104 Product Heart
"He Wei?" When Xu Qiang saw the person coming, he was stunned for a moment.

"Xu Qiang, you can't drink alcohol at work, don't you know?" He Wei said to Xu Qiang in a questioning tone.

"We are all classmates, aren't you meddling too much?"

As for He Wei, although the two were classmates in the workers' night school, they had never had much contact.

On weekdays, Xu Qiang basically didn't talk to his classmates except Wang Yongsheng and his gang. Apart from that, he only said a few words to Liu Siying. At other times, he would leave after class and would never stay for even a minute longer.

"Classmates are classmates, work is work. This is the Information Department, the most confidential place in our factory." He Wei frowned and continued, "So I have to criticize you. As an employee of a military enterprise, you must strictly abide by the factory's rules and regulations. You drink at work and come to the Information Department to check information. This in itself is a disregard for our factory's rules..."

"What the hell are you talking about?" He Wei's words left Xu Qiang confused, but when he saw the person coming up behind him, he suddenly understood.

It turned out that behind He Wei, Liu Siying and several female employees from the technical department came over together, holding rulers, pencils and other drawing tools in their hands, and it was obvious that they were going to draw pictures from the database.

Today, Liu Siying is still wearing a floral dress and white sandals, with a neat ponytail. Her delicate and fair face is eye-catching. Her 1.7-meter-tall slender figure stands out among several female workers, making her stand out a bit.

It was obvious that He Wei wanted to put on airs in front of these female workers. After all, people in the technical department were more or less arrogant and had a sense of superiority, especially when facing a temporary worker on the front line like Xu Qiang.

"Xu Qiang, you're here too." Liu Siying smiled and greeted Xu Qiang after seeing him, then said to He Wei, "What are you two talking about? Why don't you go in?"

"You smell the alcohol, it's from Xu Qiang!" He Wei looked serious, and said, "We are all disciplined and well-mannered people in our department, but there are always people outside who break the rules. If the whole room is filled with alcohol, how can we still concentrate on high technology..."

"I'm asking you, are there something wrong with your brain?" Xu Qiang said impatiently.

In fact, Xu Qiang didn't want to argue with He Wei. After all, there are all kinds of birds in the forest.

"Xu Qiang and his colleagues work very hard in the workshop. They drink to relieve fatigue. Let's understand each other." Liu Siying immediately interjected and turned to Huang Haitao and said, "Director Huang, let's go in first."

While Liu Siying was speaking, she winked at Xu Qiang.

Seeing this, Xu Qiang also walked in with the crowd.

"Thank you." After getting the materials and entering the reading room, Xu Qiang thanked Liu Siying.

"We are classmates, why should we be polite to each other?" Liu Siying replied with a smile. "I was mainly asked to see Wang Yongsheng today..."

"You don't need to explain, I'm not your leader." Liu Siying had already picked up the information and started reading it, saying without raising her head.

"Okay then." Seeing this, Xu Qiang took the information in his hand and sat down behind him.

What Xu Qiang got this time was the factory's product catalog. This thing is not confidential and is open to the public, but it is helpful for Xu Qiang to understand the situation of the factory and thus grasp the factory's technical situation.

As one of the largest third-line enterprises in Jiangxi, Shengli Machinery Factory's main products include Type 69 rocket launchers and various anti-aircraft gun and howitzer shell fuses. Among them, the electronic fuse can be said to be the flagship product of Shengli Machinery Factory. Its importance can be seen from the fact that this product is introduced on the homepage.

When the factory was first established, Shanghai Radio Factory, as the main contractor, was the first to develop the 85 cannon grenade fuse and the 59 anti-aircraft gun proximity fuse. At that time, this proximity fuse still used electron tube technology, so the stability of these two types of artillery fuses was not high and the control accuracy was poor. However, even so, relying on this product, Shengli Machinery Factory ushered in its first glorious period after its establishment. The scale of the factory gradually expanded, and more and more workers and technical talents came from all over the country. The factory eventually became the largest third-line enterprise in Jiangxi.

By 1969, Shengli Machinery Factory began to concentrate its technical talents and spent a full three years to develop the second generation of artillery shell fuzes. This fuze used infrared technology, which was relatively advanced in the country at that time. However, although this fuze was more accurate than the previous generation, it still had many problems, including poor battery quality and inability to store for a long time.

Last year, Liu Siying, who had just graduated from a technical school, made great contributions to the factory. She spent half a year collecting and reviewing a lot of foreign and internal information, and successfully developed a new generation of transistor radio proximity fuses. With this military patent, Liu Siying and her technical department were commended by the Provincial Military Industry Office and the Fifth Ministry of Machine Building, and she eventually became the youngest team leader of the technical department.

In fact, Xu Qiang is still full of respect for the history of this factory, because from a remote mountain valley where no one lives to become the largest third-line military factory in the province today, it requires a lot of hard work and dedication. It is difficult for ordinary people to imagine how many hardships and obstacles these pioneers gave up their former comfort and experienced to achieve today's results.

As Xu Qiang flipped through the product catalog, he finally discovered a problem.

If the electronic part of the fuze is the brain of the product, then the battery part is the heart of the fuze product.

From the explanation in the catalog, we learned that the zinc-manganese batteries used in the factory's early artillery fuses were also the oldest type of disposable dry batteries. This type of battery has low energy storage, and over time, the loss of stored electricity is very large, so that early artillery fuses would fail after being stored for a long time.

It was not until Liu Siying invented the new generation of transistor fuses that used nickel-chromium batteries. In fact, at this time, the country had already begun mass production of alkaline zinc-manganese batteries. Compared with ordinary zinc-manganese batteries in the early years, this type of battery has a longer storage capacity and lifespan and can be stored for up to seven years.

However, this type of battery cannot be used in artillery fuses due to limitations in size and operating temperature. In the past decade, the factory's artillery fuses have all used nickel-cadmium batteries and lead-acid batteries. However, these two types of batteries also have relatively short storage times and malfunction at extreme temperatures.

However, Xu Qiang has mastered many methods of preparing military batteries for future generations. If he were asked to solve this "heart" problem, it would definitely not be a difficult task...
