Zhang Yang received a text message from Li Yuxin: Check the quartz content.

Zhang Yang thought for a while, but still didn't understand the truth, so he came to Ah Yu's office and said to him, "Ah Yu, did you ask?" ”

"Not yet." Ah Yu didn't want to lie either, so he told the truth.

"I've got someone to ask for you." Zhang Yang pretended to be mysterious.

"How?" Ah Yu suddenly came to his senses.

"Mr. Yu said, check the content of quartz." Zhang Yang said proudly.

"Oh." Ayu nodded thoughtfully.

"How does this work?" Zhang Yang wanted to make a fuss.

"The main role of quartz in the blank is to adjust the plasticity of the mud, and can reduce the shrinkage of the green body during drying, thereby shortening the drying time and preventing the deformation of the green body. However, the firing temperature must be carefully controlled, and if the control is not good, the phenomenon of broken billet will occur. ”

"Is it because the temperature is not well controlled?" Zhang Yang asked him.

"It's going up too steeply, it's going down too hard." Ah Yu gestured as he spoke, and as he spoke, it seemed that he himself understood a lot. I saw him slap his hand violently and yelled, "I'm fucking stupid, why don't you let the kiln be adjusted?" ”

"Kiln adjustments?" Zhang Yang didn't react for a while.

"yes, let him level out the quenching temperature."

"Isn't that going to change the firing curve of the kiln?" Zhang Yang seemed to understand a little.

"yes, that's faster than adjusting the formula."

"The firing curve that can be formulated is not allowed to move under normal conditions." Fastest update on PC:/

Ah Yu suddenly looked like a defeated rooster, and his head drooped all of a sudden.

"Forget it, I'd better adjust the recipe." After that, he checked the recipe before deciding to walk towards the raw material workshop.

Zhang Yang didn't have anything to do, and he followed him to see what was going on.

In the raw material workshop, Ah Yu gave the changed formula to the director of raw materials, and the director immediately wrote the formula on the small blackboard for grinding. After the change, Ah Yu took a small bag of quartz in a plastic bag and prepared to take it back to the laboratory to test the ingredients.

Zhang Yang didn't learn anything after him, but he was bored, so he came to the place where the balls were piled up and chose two round high-alumina stones, pinched them in his hand and played all the way.

"Zhang Yang, why are you picking up two boulders?" Director Zhang saw him from the side and asked.

"Is this a boulder?" Zhang Yang pretended not to know.

"You don't know?" Director Zhang's eyes widened, unable to believe that this was true. He stared at Zhang Yang with questioning eyes, and a lotus flower secretly grew in Zhang Yang's heart.

"I don't know." Zhang Yang shook his head and continued to pretend to be stupid.

"I think you should popularize common sense." Director Zhang gave him a fierce look, and then left without looking back.

Zhang Yang whispered happily and jumped into the craft department. At this time, Ah Yu came over, he hung the plan on the wall, and suddenly saw the two stones in Zhang Yang's hand and asked, "What are you doing here?" ”

"Play." Zhang Yang did not shy away from it, and directly stated his intentions.

"You can play this too?" Ah Yu clearly didn't quite believe his words.

"Of course you can play, move your wrists." Zhang Yang took advantage of the situation and turned the ball stone in his hand a few times.

When Ah Yu saw it, it was really so, so he secretly said to him: "Do you know how to measure this specific gravity? ”

"Can this still measure the specific gravity?" Zhang Yang searched the physics knowledge in his mind, and he seemed to be blank about the proportion of the sphere.

"Okay, since you like to play so much, then you can keep playing." Ah Yu walked out of the craft department with a hearty smile.

Zhang Yang pondered Ah Yu's words, stared at the two cobblestones unconvinced, and put them on the table angrily, Lao Tzu is going to measure its specific gravity today.

Zhang Yang stayed in the room and ignored anyone, contemplating what method to use to detect the sphere.

A craftsman next to him seemed to be nodding him, muttering to himself the wind in the middle of the room: "Mass divided by volume is density." The volume of the sphere can be measured by the drainage method, the sphere is tied with a thin wire, the sphere is submerged in water, its mass is weighed, and then the ball is taken out and the mass of the water is weighed, the two are subtracted, and then divided by the density of the water to obtain the volume of the sphere. ”

The speaker has a heart, and the listener also has an intention, and Zhang Yang thanked him for his reminder with a smile. So I ran to the laboratory, found a plastic measuring cup, and implemented it one by one according to the method I had just heard, and finally calculated the specific gravity of the cobblestone. What used to feel complicated became simple in an instant after a practical operation. Update the fastest mobile phone: ://

3.58gcm³, Zhang Yang threw the result on Ayu's table, sat on the arm of his chair, and shook his feet proudly.

"Okay, I didn't expect you to get it out so quickly." Ah Yu originally wanted to wash him away, but Zhang Yang's fierce answer made him unable to start. Starting

"If I say it's me, will you believe it?" Zhang Yang began to tease.

"Do you have what it takes to be so accurate? To put it bluntly, you don't even know how much the stone weighs, how do you go to Meng? You think you're a fortune teller? "Ayu's words are not unreasonable. Who doesn't eat all day to do this.

The smugness on Zhang Yang's face disappeared in an instant, and indeed he couldn't be blinded, because he didn't even have the concept of density.

"But you're not patient." Ah Yu saw that he had frightened him, and he also took the opportunity to give him a step down.

Zhang Yang slipped down from the armrest and said with a smile, "The stroke of genius is not worth mentioning."

"Hehe, you're refreshing and honest, it seems that this drainage method is not bad, I'll remember it a few more times." Ayu guessed his measurement.

"It seems that our Minister Ayu has not yet reached the point of being rich in meat and eight vegetables." Zhang Yang said casually, it seemed to be a mouthful, but in fact, he put a lot of effort.

"Do you mean I'm old?" Ah Yu can be regarded as a god reaction.

"How dare you." Zhang Yang shook his hands and bowed to Ah Yu.

"By the way, this month's fee has come down again. But it's a little less than last time, after all, I've been tossing others for so long. "The toss Zhang Yang in Ayu's mouth is unreasonable, that is, the trouble caused by the exchange, the cost is high, of course, the rebate is less than a discount.

Taking the envelope that Ah Yu took out from the drawer, Zhang Yang only squeezed it lightly and put it in his trouser pocket.

"Next month, they have invited us, you prepare in advance, let's go for a walk." Ah Yu told him the news, and Zhang Yang suddenly came to his senses when he heard it, and asked, "There should be a special program this time, right?" ”

"What do you want?" Ah Yu didn't glance at him.

"Nightclubs. When you arrive in Foshan, you can't open foreign meat? Zhang Yang thought about massaging and singing, and couldn't help but feel overjoyed.

"We'll talk about it then." Ah Yu can't guarantee that there will be other programs, after all, we are not their biggest customers.

"What's the matter, what program will come when the time comes. I don't want to waste my energy. Zhang Yang smiled at Ah Yu, which was a mysterious and obscure smile.

"Okay, let's go and prepare for production first, there are more than 10 new suits in today's plan. It seems that the screen plate will be printed later. Ah Yu urged him to say.

"Still printing a screen version? So troublesome? Zhang Yang's eyebrows locked, one word: sorrow!

"Well, the new goods in the R&D center have not been produced by other factories." Ayu emphasized.

"It seems that this R&D center really has two brushes." As soon as he said this, Zhang Yang remembered Chen Siqi's dream again. It's just that her dream is a bit far away......
