super energy power

Seeing Shu Hao's expression, Su Cheng knew that he had crossed over. └@ ┘

He didn't dare to answer right away, pretending to ask casually: "How does your factory do electroplating?"

"What can I do? A DC generator, an electroplating tank, first grinding, then polishing, but stainless steel bars are too difficult to make. I heard that stainless steel bars were copper-plated before, but many finished products were returned by customers. The factory It was troublesome for a long time, so I changed the electroplating workshop back." Now Shu Hao is also full of disdain for state-owned enterprises.

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

"It's not because of the export. People say that foreigners like the color of copper, but copper is so expensive, so I just plate it. But it can't be sold, and it's sold in China, and then it's returned and lost money."

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

"That's why." Shu Hao didn't take it seriously. After working in the factory for three to five years, he saw a lot of all kinds of strange flowers, and he saw that the flowers were not scars.

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

"Who doesn't know how to do electroplating if there is a formula." After Shu Hao finished speaking, he asked suspiciously: "Where did you hear the formula for electroplating solution?"

Su Cheng smiled and didn't answer, thinking, if engineering students want to answer the paper by themselves, they have to memorize two electroplating solution recipes.In fact, doing electroplating is similar to making traditional Chinese medicine, and the difference is thousands of miles away.Therefore, different reagents and process conditions must be tested continuously. 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 methods have been widely used in modern times. 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 coating.

While Su Cheng was thinking, he found a piece of paper and leaned against the refrigerator to start writing.

Shu Hao stared with bated breath.After working in the factory for a period of time, he will understand various types of work. From his experience, this is at least the correct formula for the electroplating solution.

“每升70到90毫升的盐酸，温度15到30度，电流密度在10到30a之间。具体怎么镀的漂亮，就要你再试验了。”苏城将纸交给了他。

Shu Hao knows how to do electroplating, but he hesitated at this moment, and said: "I'm afraid they will learn to do experiments in the factory. When the time comes..."

These days, intellectual property rights are not discussed.Especially between public and private parties, there is no reason at all. The words "use yours is worthy of you" may not be said, at least the expressions and actions are in place.

Su Cheng said indifferently: "What are you afraid of after you have learned it? Look at the factories in the market now, which township enterprises rely on advanced technology to survive? Small businesses like you can't finish the work at all. Wait for the state-owned factory to When we are ready to compete, monopoly profits should also disappear. Therefore, what we are fighting for now is time, not the market.”

Shu Hao didn't understand half of what he heard, but he had great trust in Su Cheng, so he said, "Then I'll go to the factory to talk tomorrow."

"The liquidated damages should be set a little higher than the price of the electrolytic cell. In this way, even if they learn how to use the 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."

This paragraph, Shu Hao nodded repeatedly.He understands the time gap very well.At the beginning of making showers, one can make a profit of nearly [-] yuan. After half a year, the profit of one shower is at most [-] yuan.And it started getting tougher with the jerky shower competition.

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

With a clear goal, Shu Hao was in a good mood, he tentatively smiled and said: "Su Cheng, I see you have so many ideas, I really might as well just go to sea."

This year is a prosperous year for going to sea. If any unit does not have a person who is suspended without pay, it is too embarrassing to say hello to others when going out.

If Sioux City didn't have the 3 US dollars as a base, maybe it would be tempting, but now it is naturally rejected.

Shu Hao didn't say much, and hastily left to do the experiment.Whether he can start an electroplating business is still a matter of opinion, and he is not very confident.

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

Domestic refrigerators in this period are still mainly enough for use. It is not easy to work normally for a long time. Noise, energy consumption and humanization are not considered.Many people even dismissed the habits of foreigners as ice-making and freezing, etc., as gimmicky.

Sioux City's feeling is naturally different.

He is a person from the 21st century. It is normal to throw an ice cube into the Coke and drink lager.It is also because of its convenient quick-freezing and ice-making function that Sioux City decided to spend 3 years' wages to buy it.

If you think about it carefully, people in 87 lived in a dilapidated house, and they didn't need to pay a down payment or a loan. They still couldn't save money. Instead, they had to save money to buy electrical appliances.

After waiting for about 2 hours, a plate of ice cubes finally took shape.

Su Cheng knocked it into a water glass, poured it into a rare Coke, and a glass of Coke ice cream worth one-tenth of the wages was ready.

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

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

Beef in this era is very popular, and most of them are given by leaders with families. Think about what Director Liu said when he was pulling people, everyone in the Ministry of Petroleum has a big pork leg, and everyone has a big herring I know that things like pork legs are still rare, and cattle are naturally even rarer. As for steaks, they can't be found anywhere, and I don't know where to cut them.

Sweet and sour pork ribs are not difficult, 2 yuan can buy a catty of fat meat or a catty of short ribs, if you choose the latter, the boss may even give you a pair of kidneys.But Sioux City won't do it, and the restaurants in Dong*ying may not sell it.In the years when everyone ate elbows and twice-cooked pork, if you ordered ribs that were not on the menu, you were basically finding fault...

"Hey!" Su Cheng said silently: "Be patient for another three years, and if there is no beef seller, I will raise beef cattle myself...

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

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

"How did you come?"

"I heard from elder brother that you know electroplating, so I thought, you might know something else, so I came to ask you for advice." Shu Lan pouted her lips delicately, her red lips seemed to be oiled, and put a A long blueprint is placed on the table.

"Try my homemade iced cola." Su Cheng brazenly placed the glass in front of Shu Lan.It is not a big mistake to say that it is self-made, after all, the ice cubes inside are boiled, watered, frozen and formed by himself, and added into the glass by himself.

Shu Lan had been a little curious for a long time, she picked up the Coke lightly, took a sip, but in Su Cheng's expectant eyes, she asked doubtfully, "Is it brown sugar water with ice?"

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

"Really vulgar." Shu Lan said, still savoring slowly.Girls like sweet and sour taste, but they also think that Coke has a unique flavor.

Su Cheng picked up the large volume of design drawings brought by Shulan, glanced at it, and asked, "This is a check valve for an oil extraction machine, right? Are you designing an oil extraction machine?"

"Well. The master said that the task assigned by the higher authorities is to finalize more than 5 types of new oil extraction machines this year. They must have a long stroke, save electricity, and work stably."

Long stroke, energy saving and stable operation, the three requirements flashed through Sioux City's mind, and a word popped out immediately: double donkey head pumping unit.

This is a type of pumping unit that will be widely used in the future, and it is also the type of pumping unit that he had the most contact with and studied the most when he was in school.It didn't become popular until around 00, and it became uncontrollable in a flash.

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