Siheyuan: Starting from a fitter

Chapter 196 Studying LCD Screen

Hearing the exclamation, everyone stopped what they were doing and gathered around.

In the past, I practiced with soft fabrics, and the finished product was completely incomparable to the real one.

At first glance, it is its fashion sense, which transcends the design sense and popular elements of this era, and looks so cool.Every worker who has tried it is impressed by its comfort.

Compared with a shoulder bag, the weight is more balanced and fully conforms to the design concept of artificial mechanics, so that the weight is evenly distributed.

Workers collectively feel that this is a fashion trend, which makes people have a strong urge to own it.

Li Guocheng felt at ease, knowing that he had succeeded.

"Brothers and sisters, listen carefully. If you don't make a package in the future, you will be rewarded with 1 Hong Kong dollar. The team leader will be responsible for how to distribute it, and she will report to me."

"One bag is 1 Hong Kong dollar. According to our practice, we can produce 1 pieces a day, that's just a month, that's..." A girl muttered to herself, she was not good at detailed mathematics.

"9000," another girl gave the correct answer.

"That's 9000 Hong Kong dollars. There are 20 of us, and the average is 450 Hong Kong dollars."

"Ah, plus the basic salary, wouldn't it be 750 Hong Kong dollars, ah, we have made a fortune."

"Then if we work overtime in production, we won't be able to earn more than 8 or 9 yuan a month."

A group of girls chatted happily.

Li Guocheng gave Chen Li a look, and left the workshop with a smile.

"Don't waste time. Let's go back to work quickly." Chen Li interrupted everyone's discussion loudly.

"That's right, we can't delay making money."

The female workers swarmed back to their workstations.

Chen Li came to the studio. She knew that Li Guocheng usually stayed here.

"Sir, are the rewards too high? If so, everyone's income is generally higher than the income of those who work hard at home."

Li Guocheng is very pleased that I treat others with sincerity and others treat me with loyalty.

"Don't worry, I came to you to make you rich, not to exploit you."

Hearing such words, Chen Li's eyes turned a little red. Along the way, they met good people, but they encountered more bad guys who sucked blood and knocked bones.

"I'll take the sisters to thank you sir."

"Don't worry, go back to work. But remember to work an appropriate amount of overtime. Safety is the most important thing." Li Guocheng knew how important production safety was.

"Understood, sir, I will help you take care of the workshop."

Looking at Chen Li's leaving figure, Li Guocheng thought of Azhi. Half a month ago, she had a dream in mind and flew to her small life to work hard for his dream of being a stewardess.

Brother Hua is now staying in the shed, enjoying himself and has almost never been here again. Of course, knowing that he has a future, he is no longer willing to participate in street fights and has slowly faded out of everyone's sight.

After more than a month of running-in, the factory has now entered the formal stage. From now on, we can just leave this area to Chen Li for management.

This girl behaved more competently. In the most difficult moment, Li Guocheng took her in. Now her children live with him and are safe in the yard.

Therefore, Li Guocheng can feel her gratitude. As long as a win-win situation is achieved in the future, he will not be afraid of her being disloyal.

Wang Xiaoxuan has already seen that he has a strong learning ability. Now that he is forced by Li Guocheng to study mathematics, physics and chemistry in high school, he can also stand alone in the future.

Ma Yong runs around with his friends and has become less timid. He can face it with a smile when being kicked out by security guards, not as angry as before.It is also a material that can be made.

Now that the factory has finally taken the first step, Li Guocheng will take back his energy and continue to study LCD screens.

In order not to affect Wang Xiaoxuan's dismantling and cutting work, last week the studio was divided into two parts, Li Guocheng's laboratory to the north, and the dismantling and cutting studio to the south.

The laboratory is not big, only about 15 square meters. There is a window on the north wall for ventilation.

After reading a lot of information and digesting and absorbing it, it was concluded that among these liquid crystal materials, dialkylbenzene and its derivatives are the most commonly used.

Their preparation is relatively easy and the cost is relatively low, so they are one of the most accessible liquid crystal materials for preparing optoelectronic devices such as liquid crystal displays.

Therefore, Li Guocheng's recent research focuses on the preparation of dialkylbenzenes.

A common material required for the preparation of dialkylbenzenes is benzene, and the required dialkylbenzenes can be obtained through the substitution reaction of benzene.

The chemical formula of benzene is C6H6, which is an aromatic hydrocarbon compound and one of the simplest aromatic hydrocarbons.It can be prepared from raw materials such as fossil fuels (coal, oil, etc.) or natural gas.

In industrial production, benzene is mainly obtained through the separation and purification of by-products produced by the dry distillation of coal or the distillation of petroleum.

Therefore, benzene is very easy to obtain and the cost is also very low.

Li Guocheng took out a large wide-mouth glass bottle, which contained liquid benzene. It is an almost transparent liquid that is volatile and flammable.

Turn on the exhaust fan and start the preparation of dialkylbenzene according to the process that I have simulated countless times in my mind.

1. Use nucleophilic substitution reaction to obtain alkylbenzene;

2. Use an alkylating agent to react an alkylbenzene with another alkylbenzene molecule to generate a dialkylbenzene under acid catalysis.

It's that simple and took just over 40 minutes to get.

Dialkylbenzene is a colorless liquid, similar in appearance to benzene, aromatic, and has a special aroma similar to benzene.

Due to its strong toxicity, Li Guocheng wore a gas mask the whole time.After the experiment was completed, the dialkylbenzene was collected in another wide-mouth glass bottle, and the stopper was tightened.

The next step is to prepare liquid crystal materials: prepare the liquid crystal mixture, filter, condense, and make precise adjustments. It only took more than half a month to obtain the optimal ratio.

Now that we have the best liquid crystal material, the next step is to develop the final LCD screen.

Firstly, a dielectric material with good light transmittance, flexibility and stability was selected as the research and development object.However, during the experiment, he found that the dielectric material is not stable enough and is easily deformed by external influences such as temperature and humidity.

A week passed quickly, and Li Guocheng had no choice but to temporarily put down the work at hand.Because Wang Xiaoxuan has approached him many times, and now he has produced nearly 3000 backpacks. What should he do if he takes over?
Li Guocheng arranged for them to continue production and called Ma Yong over.

"Ayong, are you feeling a little stressed lately?"

"It's okay." His eyes were obviously a little dodgey.

"Haha, it's normal. Looking at the money being made in the workshop, don't you feel a little uncomfortable with only a basic salary and a subsidy of 200?"

Ma Yong was a little embarrassed, and smiled.

"Starting from tomorrow, all of you will carry backpacks during the day and show off to me. When someone asks, you will say that this is the latest product of Hualong Technology and it is very expensive!
Then hire someone to go to the night market at night and take photos of the bags and ask the vendors where to buy them?A week later, you can contact these vendors again."

Li Guocheng did not explain to them that this was a bad marketing technique for future generations, and the results would be seen in due course.
