In two days, Zhang Xiaofan took Deng Xiaoni and ran to seven or eight houses.

Basically everyone agreed to try it.

Zhang Xiaofan didn't go to Li Feiyun's side at all, because the gloss of the paint used by Li Feiyun was just seven degrees.

This is not Zhang Xiaofan's eccentricity, but these ceiling manufacturers have from four degrees to ten degrees.

Zhang Xiaofan just took a middle number, and then just matched the gloss degree used by Li Feiyun's company.

This time Deng Xiaoni was really eye-opening.

However, she has always had a question, Zhang Xiaofan, how did this conclusion come about.

"Mr. Zhang, when did the company do such an experiment?"

"I haven't done it yet. ”

"Ahh......h

Zhang Xiaofan understood what Deng Xiaoni meant.

In other words, why did you Zhang Xiaofan deceive these customers?

"Actually, it's four degrees, seven degrees, ten degrees.

They are all paints for ceilings, and there is no difference in their color, only a little difference in gloss.

In fact, when they are installed on the ceiling, the difference is not very big.

And between the degrees, the performance of the product has not changed fundamentally. ”

"That ......"

Zhang Xiaofan was more puzzled, didn't Chen Ying tell Deng Xiaoni why Zhang Xiaofan did this?

"In order to reduce our production costs, it is equivalent to combining seven or eight different products into one, reducing the expenditure of manpower and material resources. ”

Deng Xiaoni suddenly realized that this was the reason.

"So, in the future, if you come across these colors with a gloss difference of less than 3%, you have to convince them as much as possible to use our No. 1 product, which is the largest production volume.

This will be very obvious in terms of savings in terms of manpower and material resources.

Not to mention too much, saving one or two million a year is casual. ”

Deng Xiaoni's eyes widened, will there be so many?

Zhang Xiaofan nodded.

I haven't been to the technical department for two or three days, and after Zhang Xiaofan and Deng Xiaoni separated, he came directly to the technical department.

Zhang Xiaofan is still quite satisfied in the past few days, not to mention saving a lot of money for the company, Liu Qi did not call.

Even if he didn't develop anything, as long as he did it with his heart and in the chosen direction, no major mistakes occurred.

Zhang Xiaofan felt that Liu Qi was worth cultivating.

Seeing Zhang Xiaofan coming, everyone did not stop their work.

Just glanced at it, then called Mr. Zhang and continued to work.

That's nice.

Walking to the office of the technical department, Zhang Xiaofan saw Liu Qi writing and painting something.

Without interrupting him, he sat down quietly on the sofa next to him.

Within a minute, Liu Qi saw Zhang Xiaofan sitting on the sofa and immediately stood up.

Then he ran over and poured Zhang Xiaofan a glass of water.

"Mr. Zhang, I'm sorry, I didn't see it just now. ”

"It's alright, how's it going?"

This is what Zhang Xiaofan is most concerned about, the result of the experiment will be directly related to Zhang Xiaofan's senses of Liu Qi, and whether Zhang Xiaofan's plan can be carried out now.

Liu Qi straightened his face.

"Now that we've made a couple of versions, I've found that adding different additives makes the paint fluoresce differently when it's not light.

That's why I made several varieties last time. ”

Wait a minute, Zhang Xiaofan will be interested, it seems that he has underestimated Liu Qi's ability, originally Zhang Xiaofan thought that he could only make the foundation, but he didn't expect to even make a variant.

"Take me to see it. ”

Liu Qi took Zhang Xiaofan to the closed dark-free room, and then took out a few small samples with different numbers.

Put it in the light box to irradiate, because you only need to see the color of her words to fluoresce, so it doesn't need to be irradiated for a long time, four or five minutes is enough.

Some glow faintly yellow, others glow purple, and some glow blue.

Liu Qi's ability was beyond Zhang Xiaofan's expectations, in fact, Zhang Xiaofan, who was glowing with purple light, didn't know how to match.

But Liu Qi made it.

"It was nice and totally exceeded my expectations. ”

A smile appeared on Liu Qi's face, it was really not easy to get Zhang Xiaofan's praise.

"Actually, I didn't do much, the basic formula you prescribed, it's basically perfect, we did a lot of experiments, even if you modify it by one percent, it will change the degree of luminescence.

I've only changed a couple of fluorescent additives slightly. ”

Zhang Xiaofan patted Liu Qi's shoulder and smiled.

Zhang Xiaofan's basic formula is indeed close to the point of perfection.

But if you want to change the fluorescent color it emits, you need to use your brain, after all, the light emitted by ordinary fluorescent agents is yellowish.

Want to turn this yellowish into a yellowish green, a blue, a purple.

In fact, Zhang Xiaofan doesn't have much confidence, sometimes if you deviate a little bit, the color will change, especially the purple light.

Although this kind of paint does not emit light by itself, it mainly stores light energy through the irradiation of light, and then slowly releases light energy in an environment without light.

Due to the addition of different additives, the light energy emitted by it will take on different colors.

Zhang Xiaofan tried the effect, and it was indeed quite good, and it was blurry in the darker places of the wide line, and the fluorescence could be seen.

Of course, Zhang Xiaofan is not satisfied with this.

"This batch of fluorescence works pretty well, but I hope you'll dig a little deeper.

In the case of faint light, how to make it shine dazzlingly. ”

Liu Qi was stunned for a moment, this first generation has not yet been perfected, why is it necessary to start developing the second generation.

Will it be too fast, the stability of the first generation of products still needs to be studied, how to start developing the second generation, in case the first generation of product formula is not perfect, it may cause a series of problems.

"This hasn't been mass-produced yet, what if the recipe is unstable?"

Zhang Xiaofan naturally knew what Liu Qi meant, and the formula of the second-generation product must have been developed on the basis of the formula of the first-generation product.

Therefore, the stability of the first generation of products is directly related to whether the second generation of products can be successfully developed.

But the formula is stable and unstable, Zhang Xiaofan is actually very sure, after all, he has not changed the big ingredients, and the formula is brought by Zhang Xiaofan.

But Zhang Xiaofan can't say that I'm sure there will be no problems with the formula.

"Then you should hurry up the time and quickly confirm whether the formula is stable, after all, time waits for no one!"

Although I don't know Zhang Xiaofan, what is the reason for the lack of time!

However, Liu Qi still nodded patiently, indicating that there was no problem, but what Zhang Xiaofan said, in the light, emitting dazzling light, Liu Qi had no clue at all, so he had to ask Zhang Xiaofan.

"Mr. Zhang, what kind of additives do you add to this prescription?
