Seeing Shu Hao's expression, Su Cheng knew that he had traveled through time.

He didn't dare to answer immediately, and pretended to be careless and asked, "How did your factory do electroplating?"

"How can I do it? A DC generator and an electroplating tank are polished first and then polished, but the stainless steel strips are too difficult to make. I used to hear that the stainless steel strips were plated with copper, but many finished products were returned by customers. The factory manager thought it was troublesome, so he changed the electroplating workshop back." Shu Hao now has a disdain for state-owned enterprises.

Su Cheng asked in surprise: "Why must copper be plated?"

"Isn't it just for exporting to make trouble. People say that foreigners like the color of copper, but copper is so expensive, so just plating copper. As a result, it can't be sold, and it's sold in China, and then it will lose money if the return is lost."

“What money can you save on copper plating on stainless steel…”

"So." Shu Hao didn't care. He worked in the factory for three or five years and saw many strange creatures, but he wouldn't see them.

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

"Who can't do electroplating if there is a formula?" Shu Hao said, asking suspiciously: "Where did you hear the electroplating solution formula?"

Su Cheng smiled but didn't answer, thinking that if engineering students want to answer the paper by themselves, they must remember the recipes of two electroplating solutions. In fact, electroplating is similar to traditional Chinese medicine, and the difference is a slight mistake. Therefore, different reagents and process conditions must be constantly tested. In addition to the guidance of theoretical knowledge, accumulation is also very important.

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

However, at the beginning of the business, there was no big problem with using the oldest DC generator to coat the coating.

While thinking, Su Cheng found a piece of paper and leaned against the refrigerator and started writing.

Shu Hao stared at the breath. After working in the factory for a while, all kinds of jobs will understand. Judging from his experience, this is at least a plating solution formula.

"Each liter of 70 to 90 ml of hydrochloric acid has a temperature of 15 to 30 degrees, and the current density is between 10 and 30 a. You will have to test it again when the plate is beautiful." Su Cheng handed the paper to him.

Shu Hao knows how to do electroplating, but hesitated for a moment and said, "I'm afraid they can learn it when doing experiments in the factory. At that time..."

In these days, there is no intellectual property rights. Especially between the public and the private sector, there is no reason. The words "who look down on you" may not be said, but the expressions and actions are at least in place.

Su Cheng said indifferently: "What are you afraid of after learning? Look at the factories on the market now, which township enterprise survives by relying on advanced technology? You can't finish small-scale errands like you. When the state-owned factories are ready to compete, the monopoly profits should disappear. So, now we are competing for time, not the market."

Shu Hao could not understand it, but he trusted Su Cheng very much, so he said, "Then I will go to the factory to talk tomorrow."

"The liquidated damages must be set a little higher than the price of the electrolytic battery. In this way, even if they learn how to make an electrolyte, they are reluctant to break the contract. They would rather build one themselves. The time they buy is all your profit."

During this period, Shu Hao nodded repeatedly. He understood the difference in time. When he started to do a shower, one could make a profit of nearly 100 yuan. Half a year passed, and the profit of one shower was at most 20 yuan. And there was competition for showers that cut corners, and life became 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 smiled tentatively: "Su Cheng, I see that you have so many ideas, so why don't you go into the sea as well."

This year is the prosperous year for going into business. If any unit does not have a person who has stopped paying and staying at work, it will be embarrassed to say hello to anyone when they go out.

If Su Cheng hadn't had the 30,000 US dollars as the foundation, he might have been moved, so he would naturally refuse now.

Shu Hao didn't say much, and hurriedly said goodbye to do the experiment. Whether he could start the electroplating business by himself was still a bit different, and his confidence was not very strong.

Su Cheng chuckled and continued to study the ice maker on the refrigerator.

During this period, domestic refrigerators were still mainly sufficient, and it was 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 ice making and ice making, which are even more fancy.

The feeling of Sucheng is naturally different.

He was a man from the 21st century, and it was normal to throw ice into Coke and drink fresh beer. It was because it had the convenient quick freezing function that Sucheng decided to buy it for three years.

If you think about it carefully, people in 1987 live in dilapidated houses and don’t have to pay down payments or loans, they still can’t save money. Instead, they have to save money to 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 a water cup and poured it into a coke easily. A cup of coke worth one tenth of the salary was ready to soak it in ice.

Facing the glass to the window, you can see the strange colors of the sun.

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

Beef in this era is very popular, and it is mostly given by leaders with family and family. Think about what Director Liu said when he was pulling people, everyone in the Oil Ministry has big pig legs during the Chinese New Year, and everyone has big bluefish. If you know that pig legs are still rare, there are naturally even fewer cows. As for steak, you can’t find the cows everywhere, and you don’t know where they have cut them.

It is not difficult to buy sweet and sour pork ribs. You can buy a pound of fat meat or a pound of small pork for 2 yuan. If you choose the latter, the boss may even give you a pair of waist. But Sucheng doesn’t know how to make it, and the restaurants in Dong*ying may not be sold. In the years when everyone eats elbows and refried pork, ordering the ribs that you don’t have on the menu is basically equivalent to finding fault...

"Hey!" Su Cheng murmured: If I endure for another three years, if there is no beef seller, I will raise beef cattle by myself...

Outside the window, a "hehe" chuckle suddenly came.

Outside the glass beside the door, Shulan's pink cheeks were faintly visible.

"Why are you here?"

"I heard from my brother that you know electroplating, so I thought, maybe you know something else, so I asked you for advice." Shu Lan pouted her mouth cutely, her red lips were as moist as if she was coated with oil, and she placed a long design drawing on the table.

"Try my homemade ice coke." Su Cheng arrogantly placed the glass in front of Shu Lan. It was not a big mistake to say that homemade was made. After all, the ice cubes inside were boiled by him, watered by himself, quickly frozen and formed, and added to the glass himself.

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

Su Cheng was absolutely in amazement and said, "But it's more expensive than three kilograms of brown sugar."

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

Su Cheng picked up the large roll of design drawings brought by Shu Lan, looked at them, and asked, "This is a single-flow valve of the oil harvester, are you doing the design of the oil harvester?"

"Well. Master said that the tasks assigned by the above must be fixed this year with more than 5 new oil production machines, which must be long strokes, save electricity, and work stably."

Long stroke, energy saving and stable operation, three requirements turned around in Sucheng's mind, and the words immediately jumped out: Double donkey-headed oil pump.

This is a very widely used oil pump in the future. It is also the one he had the most contact and research when he was in school. It did not begin to become popular around 2,000, and it was out of control in a flash.

"I'm so stupid." Su Cheng slapped himself hard, turned around and went to find his drawings and pencils.
