Chapter 29 Coke with Ice

Su Cheng looked at Shu Hao's expression and knew that he had traveled through time.

He didn't dare to answer immediately and pretended to ask inadvertently, "How does your factory do electroplating?"

"What can I do? A DC generator and an electroplating tank are polished first and then polished, but the stainless steel strip is too difficult to make. I heard that the stainless steel strip has been coated with copper before, but many finished products have been returned by customers. The factory director thought it was troublesome, so he changed the electroplating workshop." Shu Hao is now full of disdain for state-owned enterprises.

Su Cheng asked in surprise, "Why do you have to be plated with copper?"

"It's not the way to make trouble. It is said that foreigners like the color of copper, but how expensive copper is, just plated copper. As a result, it can't be sold, and it is sold in China, and then you will lose money by returning the goods.

"How much money can you save by plating copper on stainless steel..."

"That's why." Shu Hao didn't care. After working in the factory for three or five years, he saw a lot of strange things, and he saw that it was not a scar.

Su Cheng shook his head and said, "I remember the formula of two electroplating solutions. With this, can you do electroplating?"

"Who can't do electroplating if there is a formula." After saying that, Shu Hao asked suspiciously, "Where did you hear the electroplating solution formula?"

Su Cheng smiled but did not answer, thinking that if engineering students want to answer the paper by themselves, they must remember two electroplating solution formulas. In fact, electroplating is almost the same as dispensing traditional Chinese medicine, and the difference is thousands of miles. Therefore, it is necessary to constantly test different reagents and process conditions. In addition to the guidance of theoretical knowledge, it is also very important to accumulate.

Stainless steel electroplating is a relatively difficult method. In modern times, PVD vacuum coating and thermal spraying have been widely used. These two methods are the widely used copper plating methods.

However, at the beginning of the business, it was not a big problem to use the oldest DC generator for plating.

As Su Cheng thought, he found a piece of paper and leaned on the refrigerator to write.

Shu Hao held his breath and stared. After working in the factory for a period of time, he will understand all kinds of work. From his experience, this is at least an electroplating solution formula.

"70 to 90 milliliters of hydrochloric acid per liter, the temperature is 15 to 30 degrees, and the current density is between 10 and 30A. How to make the plating beautiful, I need you to test it again. Su Cheng gave him the paper.

Shu Hao can do electroplating, but at this time, he hesitated for a moment and said, "Do experiments in the factory, I'm afraid they will learn it. When the time comes..."

In this year, we don't talk about intellectual property rights. Especially between the public and the private, it is even more unreasonable to say that "I use yours to think highly of you" may not be said, and the expression is at least in place.

Su Cheng said indifferently, "What are you afraid of when you learn? Look at the factories on the market now. Which township enterprise depends on advanced technology to survive? If you are such a small fight, you can't finish the work at all. When the state-owned factory is ready to compete, the monopoly profit should also disappear. Therefore, what is competing for now is time, not the market.

Shu Hao didn't understand, but he trusted Su Cheng very much, so he said, "Then I'll go to the factory tomorrow to talk about it."

"The liquidated damages are slightly higher than the price of the electrolyte pool. In this way, even if they learn the practice of electrolyte, they are reluctant to break the contract. They would rather build a new one by themselves. The time they buy is all your profit.

In this paragraph, Shu Hao nodded repeatedly. He understands the time gap very well. At the beginning of making a shower, one can make a profit of nearly 100 yuan. After half a year, the profit of a shower is up to 20 yuan. And there is a shower competition to cut corners, and life is getting more and more difficult.

Electroplating is also a simple process, and it is easy to learn.

With a clear goal, Shu Hao was in a good mood and said with a tentative smile, "Su Cheng, I think you have so many ideas. It's better to go to the sea."

This year is a prosperous year for going to the sea. If there is no person on leave without pay in any unit, it will be embarrassed to say hello to others when you go out.

If Sucheng didn't have the bottom of the 30,000 US dollars, he might have been moved. Now he naturally refuses categorically.

Shu Hao didn't say much and hurriedly said goodbye to do the experiment. Whether he can start the electroplating business or not, he is not very confident.

Su Cheng smiled and continued to study the ice machine on the refrigerator.

Domestic refrigerators in this period are still mainly enough, and it is not easy to work normally for a long time. Noise, energy consumption and humanization are not yet considered. Many people denounce the habits of foreigners such as making ice, ice, etc. as fancy.

The feeling of Sucheng is naturally different.

He is from the 21st century. It is normal to throw an ice cube into the coke and drink fresh beer. It also saw that it had a convenient quick-frozen ice function, so Su Cheng decided to buy it for 3 years' salary.

Think about it carefully, people in '87 live in dilapidated houses. They don't have to pay down payments and loans. They still can't save money. Instead, they have to save money and buy electrical appliances. The young man's marriage pressure is not small at all.

After waiting for about 2 hours, a plate of ice was finally formed.

Su Cheng knocked it into the water cup, poured it into the coke, and a cup of coke ice worth one-tenth of the salary was ready.

Put the glass out of the window and you can see the strange color of the sun.

Su Cheng looked over and over again, and suddenly missed the steak and sweet and sour pork ribs.

The beef of this era is very popular, and it is mostly given by the leaders who have families and rooms. Think about what Director Liu said when he pulled people, everyone in the Ministry of Petroleum has a big pig's leg during the Spring Festival. Everyone has a big herring and knows that pig's leg is still rare, and there are naturally fewer cattle. As I don't know where to cut it.

Sweet and sour spare ribs are not difficult. You can buy a catty of fat or a catty of small spare ribs for 2 yuan. If you choose the latter, the boss may give you a pair of kidneys. But Sucheng can't do it, and the restaurants in Dong*ying may not be sold. In the years when everyone eats elbows and twice-cooked pork, you order the ribs that are not on the menu, which is basically equivalent to looking for chops...

"Hey!" Su Cheng meditated: If I don't sell beef for another three years, I will raise my own beef...

Outside the window, there was a sudden "hee hee" laughter.

Outside the glass by the door, Shu Lan's pink cheeks loomed.

"Why are you here?"

"I heard from the eldest brother that you know electroplating, so I thought that you may know something else, so I came to ask you for advice." Shu Lanjiao pouted, her red lips moistened as if they were oiled, and put a long design on the table.

"Try my homemade ice cola." Su Cheng put the glass in front of Shu Lan with shame. It's not a big mistake to say that it's homemade. After all, the ice inside is boiled by himself, watered by himself, quickly frozen and formed by himself, and added to the glass by himself.

Shu Lan had been a little curious for a long time. She gently picked up the coke and tasted it, but in Su Cheng's expectant eyes, she said doubtfully, "Is it brown sugar water with ice?"

Su Cheng fell down and said, "But it's more expensive than three catties of brown sugar."

"It's really vulgar." Shu Lan said that she still tasted it slowly. Girls like sweet and sour, but they also think Coke has a unique flavor.

Su Cheng picked up the large roll design drawing brought by Shu Lan, looked at it twice, and asked, "This is a single-flow valve of an oil extractor, right? Are you designing an oil extractor?"

"Hmm. Master said that for the tasks assigned above, more than five new oil recovery machines must be fixed this year, which must have a long stroke, power-saving and stable work.

Long stroke, energy saving and stable operation, the three requirements turn in Sucheng's mind, and a word immediately pops up: double donkey head pumping machine.

This is a kind of pumping machine that will be widely used in the future, and it is also the kind of pumping machine that he has the most contact with and researched most when he was in school. It was not until about 2000 years ago that it began to be popularized, and it was out of control in a flash.

"I'm so stupid." Su Cheng slapped himself fiercely and turned to find his drawings and pencils.
