Reborn in 1981, the first to get rich start with dairy cows.

Chapter 172 Showing off skills, I, Shen Dong, am the best at it.

The glass products industry is currently facing considerable challenges.

Take the county glass factory as an example. In addition to traditional glass, it also produces glass bottles, jars, and glass cups.

However, the yield rate has remained consistently high.

A large part of the reason is that glass bottles are made by "blowing"!

After the molten glass is clarified, the worker blows it into the mold, so the molding effect depends entirely on the worker's skill.

In addition, the bubbles and impurities in the molten glass are removed by simply letting it stand, without any equipment to help clarify them, so it is difficult to guarantee the quality.

This makes it difficult to increase current production levels.

However, to meet the needs of dairy factories, current production needs to be increased by at least two to three times.

Shen Dong thought about it himself and realized it was all a pipe dream.

But who told him to have cheating tools? It's just a matter of two, two, three, four, and then another round.

After several days of preparation, Shen Dong had prepared all the questions he needed to consider.

Shen Dong rode his bicycle and called Li Hu, and they arrived at the county glass factory.

Inside the factory area, piles of glass shards gleamed blindingly in the sunlight.

"Factory manager, this glass looks alright, why were you destroying it? Isn't that a huge waste?"

Shen Dong explained with a smile, "It looks fine from a distance, but you'll find all sorts of problems once you get closer."

"Even if there are problems, they don't have to be destroyed, can't they be recycled?"

"Don't ask this question in front of others. The energy consumption generated by recycling is enough to offset the cost, and it will increase even more, so it's not a worthwhile thing to do."

"Tsk tsk, what a waste!"

After informing the gatekeeper, factory director Zhang Jianguo quickly came out to greet them.

"Director Shen, I've heard so much about you!"

Shen Dong looked at the hand being held tightly and was touched by his enthusiasm.

"I apologize for the intrusion."

"Oh, what are you saying? I'm overjoyed you're here, how could it be a disturbance! Come on, let's go inside and talk."

Zhang Jianguo brewed a pot of coarse tea and said frankly, "Director Shen, I am naturally very pleased that you have come to our glass factory to make purchases."

"But to be honest, we are indeed facing many difficulties right now, and I'm afraid we can't meet your needs immediately."

Shen Dong picked up his teacup and smiled: "I am somewhat aware of these situations, but I believe that with the technology of our glass factory, we can definitely solve them."

"It's difficult. Wait a moment, I'll call Engineer Li from our factory over."

A short while later, he brought in an elderly master craftsman.

"Director Shen, the factory manager of Jinru Yogurt, is here to purchase glass," Zhang Jianguo said with a smile, pointing to Shen Dong.

"Purchasing glass?" Engineer Li frowned. "We can't even finish our daily quotas right now, and we can't even keep up with the queue of people waiting to buy glass."

"Engineer Li, I know all this. I wouldn't want to make things difficult for your glass factory. There will definitely be a lot of people in the queue."

Then, Shen Dong said to Zhang Jianguo, "Besides purchasing glass bottles, I also have another idea for me to come here this time: to discuss the problems we are currently facing with our technical staff."

I have read a lot of technical articles before and have some knowledge of glassmaking.

As he spoke, he gave Engineer Li a modest smile.

Engineer Li was taken aback for a moment, then pursed his lips and gave a perfunctory smile.

I imagine they don't agree with it in their hearts.

Shen Dong had seen this kind of scene many times before, so he didn't care and asked about it.

"What's the temperature inside your vat furnace right now? 1400 or 1500 degrees Celsius?"

Engineer Li showed a hint of shock.

Wow, you're really good at this!

However, he quickly concealed his feelings and said calmly, "Yes."

"What's the ratio of quartz sand, pure alkali, and limestone?"

"There's no exact ratio, but it's roughly 72% quartz sand, 20% pure alkali, 0.6% limestone, and a small amount of dolomite. Generally, it's based on the craftsman's experience to determine the proportions."

Shen Dong revealed a knowing look, then said, "Handmade? What if there's an error? Wouldn't that cause problems?"

Faced with the questioning, Engineer Li showed a contemptuous expression.

"If something goes wrong, why would you call on a master craftsman? He must have gone through thousands of trials and tribulations; he's definitely not going to make a mistake."

"If even programs can make mistakes, what about humans?" Shen Dong muttered to himself, and before the other person could hear him clearly, he continued.

"I have a proposal, Mr. Li, could you listen to it and give me some pointers?"

Although he had been questioned twice, it was clear that Shen Dong had some understanding of the matter and wasn't just a naive newbie. Engineer Li's face remained expressionless as he nodded, "I'd like to hear more!"

"Director Shen is involved in this area?" Zhang Jianguo, who had been listening to the conversation, belatedly realized that Shen Dong was serious.

"Haha, I know a little bit!"

Shen Dong replied briefly before continuing, "First, there's the kiln temperature. Engineer Li already explained your current situation. If the kiln temperature is different at different stages of glass melting, wouldn't that prevent glass deformation and reduce bubbles?"

Engineer Li murmured, "Different temperatures at different stages?"

He thought for a moment, then asked, "What are the specifics?"

"The melting stage reaches 1500 degrees Celsius, the clarifying stage reaches 1400 degrees Celsius, and the shaping stage reaches 1200 degrees Celsius!"

Instead of questioning him immediately, Engineer Li carefully took notes in his notebook.

"Director Shen, please continue." He had become serious this time, and said in a steady tone.

"Secondly, the raw material ratio is crucial. The proportions of quartz sand, pure alkali, and limestone must be precise! Glassmaking ultimately comes down to..."

The bottom line is still closely related to the numbers. If the numbers fluctuate up and down, then naturally the yield rate will also fluctuate significantly.

"Let me interrupt for a moment," Zhang Jianguo suddenly said with a smile, "Engineer Li also wants to achieve the precise proportions, but he doesn't have the equipment. We're a state-owned factory, but as you know, we have a low status. When it comes to equipment, others have to get it first."

"I understand!" Shen Dong replied with a smile, then continued to say to Engineer Li, "I have a recipe ratio that you can try."

"Go on!" Engineer Li quickly picked up his notebook, looking like he was studying diligently.

Seeing his expression, Shen Dong was secretly overjoyed.

When it comes to showing off skills, I, Shen Dong, am the best at it.

"70% quartz sand, 20% pure alkali, 8% limestone, with a small amount of dolomite. However, the raw materials need to be thoroughly dried before mixing to avoid moisture contamination."

If conditions permit, add simple measuring tools to reduce biases caused by experience.

Engineer Li nodded and asked, "Director Shen, is there anything else? If not, I'll go and test it now."

"Don't rush, there's another thing to note."

As soon as Shen Dong finished speaking, Engineer Li, who had just turned halfway around, immediately turned back around.

"It would be best to install a simple air-cooling device on the outside of the mold, which can speed up the cooling process and reduce the possibility of glass deformation."

"That's a great idea. Cooling does take up a lot of time." Engineer Li clapped his hands and cheered.

Shen Dong thought to himself: How could it not be good? This is the essence of decades of concentrated essence.

"Also, the annealing process must be standardized, and the cooling rate must be well controlled."

"I know that; our master is experienced."

After confirming that Shen Dong had nothing else to say, Engineer Li left anxiously.

He couldn't wait to experiment.

"This old Li is just an impatient guy," Zhang Jianguo said with a smile, pointing at him.
