At this time, the onlookers also began to make a big talk:

"It is estimated that the furnace can burn pulverized coal......"

"Of course, but if burning heavy oil is the best, no matter what, I dare say that the quality is okay, and the transparency is definitely much stronger than ground glass!"

"An-la! Although the process of making flat glass is a bit backward, these two miniature soda-lime glass electric melting furnaces are really advanced things! ”

"Holy! ...... Micro electric furnace, Nissan ...... The discharge is about 300 kilograms, all electromelted! Very nice equipment this is! ”

"It's still good, the most praised thing is that the spare parts graphite electrodes have been given a lot, and they have been used for a long time....."

This group of science and engineering men is in a heated discussion, but the onlookers and melon-eating crowds are gone, and now everyone knows the strategic role of the glass industry in this crossing collective, so they are very concerned to ask them questions outside the circle.

"Hey! Wait a minute! Don't have a small meeting! ”

"Tell us about it!"

"Mr. Zhao, give us a general explanation!"

"Teacher Zhao, Brother Hou, what did you say just now? I seem to hear the word frosted glass! ”

"Holy! Frosted glass! ”

"Huh? Someone just said what the hell is ground glass? ”

"What? Don't play with us, frosted glass? The kind of glass that isn't very transparent? ”

"Damn! I'd like the Gunnery Mirror! ”

"I heard that three hundred years ago, everyone in the Venetian could have a telescope! Don't tell us you can't make clear glass?! ”

"Yes, the high-grade optical telescopes produced by the Europeans at that time could see the craters on the moon!"

It was a group of high school students who said these words, apparently they learned some knowledge when they took the holographic simulation reality culture class in the past two days, and immediately used it to be fried and sold.

"I'm talking about large-scale mass industrial production here, and it's not done by hand, I'm afraid it can't be compared, right?"

Teacher Zhao looked up and responded to the high school students.

"What! I want clear glass anyway! My military telescope ......"

"Don't forget the Gun Mirror!"

So the science and engineering men who were discussing the list of equipment in the glass factory with their partners around them were immediately pulled back to reality by the complaints of the melon-eating masses, and Mr. Zhao hurriedly came forward and raised the paper in his hand to explain to everyone:

"Hey, I'm sorry, I'm sorry, what, colleagues, students, we can guarantee that the flat glass produced is basically transparent!"

"What do you mean by basic transparency?"

Judging from the surprised expressions of everyone, the people who eat melons are obviously very dissatisfied.

"Oh, slip of the tongue! I mean, because the process is quite backward, it is estimated that the initial rejection rate is relatively high, and there are not many transparent glasses, which is not nothing! ”

At this time, Hou Xianglin also hurriedly came out to explain.

"Okay, okay, but even if there are such and such problems, this is the first industrial glass production plant in the New World after all, the industrial scale is there, and the technology is very mature, we should be able to produce qualified clear glass, as for the cost, I think it's much lower than the Venetian anyway, right?"

Qiao Xiaomu, a professional in the chemical group and a technician from a fine chemical company, came forward to explain to everyone, and then turned his face to Mr. Zhao and Gui Xianning in the chemical group.

"Brother Xiaomu is right, regarding the transparency of glass, we should have this certainty."

Gui Xianning also nodded and confirmed the former's statement.

"Yes, as long as the temperature is up to ......"

Teacher Zhao pondered for a moment and responded.

"Mr. Zhao is really amazing, and he got to the point in one sentence, temperature, and it is temperature that is the most critical factor for us to lead the Europeans. But rest assured, the temperature should be fine, and if the power supply is guaranteed, this can be fully satisfied. ”

Hou Xianglin concluded.

"Therefore, the transparency of our glassware must be higher than that of the Venetians, so don't worry!"

"That's right! After all, these electric melting furnaces can be said to be the hottest furnaces in the world......"

Two members of the chemical engineering team on Mr. Zhao's side also spoke and explained to everyone.

"Really?"

"It has to be true! Moreover, the benefits of the flat pull method are also obvious, the process is simple, and the requirements for raw materials and tooling are not high. ”

Gui Xianning's tone was very determined.

"Of course, there is a key factor in our soda ash production, and the purity has to keep up."

Well, Mr. Zhao has another key sentence.

As soon as the topic shifted to chemical engineering, a group of science and engineering men immediately became serious.

"Well, soda ash is the key ......"

"We have to start from the beneficiation link."

"And calcination ......"

"If the industrial purity is reached, it will not only meet our initial development requirements, but also meet our future industrialization needs."

At this time, Gui Xianning whispered.

"Soda ash? Isn't it just soda? It should be fine for you in the chemical industry, right? ”

Someone in the melon-eating crowd asked.

"Uh...... We seem to have the conditions for the alkali method, right? ”

However, at this time, the people in the chemical industry group did not respond to outsiders, but whispered discussions there.

"Anna gave us the equipment for the alkali method, but we don't need it now! Unless we come up with ammonia ...... soon."

"So, the coal and coke chemical industry must go ahead!"

"Mr. Zhao, there was a Lubran alkali method in history, you always think ......"

"That also needs to produce sulfuric acid!"

"So, ah, three acids and two bases must be on! Even if the output is less and the quality is poor, these must be there! ”

"In fact, the quality of the glass at the moment still depends on the quality of quartz sand, and this island happens to have very high-quality quartz sand!"

Cao Limei interjected next to her and added, which can be regarded as responding to everyone's questions from the side.

"Really? But I've heard that the quality of glass depends largely on soda ash, which seems to have been taught in high school chemistry class, right? You're always a chemistry teacher, am I right? ”

Seeing that some people in the crowd were questioning, Mr. Zhao had no choice but to terminate the internal discussion and said to everyone:

"That's right, the transparency of this glass is not only related to the quality of raw materials and soda ash, but also the furnace temperature! We need to experiment before we dare to say, but since Anna gave us this equipment, it is not just for us to make ground glass, otherwise what is the point of this equipment?

In fact, what I am most worried about is the quality of soda ash, if you want to obtain soda ash, you must have ammonia, if you want to have ammonia, according to our current conditions, you must engage in coal dry distillation, of course, soda ash also has other methods to prepare, but the production efficiency is not high......"

Zhao Xihe patiently explained a lot to everyone......

"Gee, is it that complicated?"

"Holy! Such a twist and turn, huh? ”

"We have the conditions for coal dry distillation, and it just so happens that we have coal coke chemical equipment, which is miniature!"

Gui Xianning interjected in time.

"Hey, that's good, that's good, let's not ask, I'm afraid it's going to get farther and farther if we ask, let's go back to the building materials and equipment, Foreman Hou, what is your opinion?"

It was rare for the people who ate melons to realize that the current topic was a bit crooked, so some people hurriedly came out to correct it.

"I have no opinion, anyway, the building materials industry is inseparable from the help of the chemical industry, it seems that we are going to prepare for joint technical research."

At this time, Hou Xianglin's tone was light.

"Well, what else is there for the glass industry?"

The crowd began to ask questions again.

"We have a miniature electric melting furnace, as well as a miniature glass mouthpiece, a miniature row bottle making machine and two micro row bottle making machines, which are pressure blown, single row and single row, just two rocker arms, even so, both product quality and production efficiency can be thrown off the eight streets! Of course, the disadvantage is that it consumes electricity, and the furnace power is 15 kilowatts, which can probably only be solved by special line hydropower......"

Hou Xianglin replied immediately.
