Su Cheng looked at Shu Hao's expression and knew that he had crossed over.

He didn't dare to answer immediately, and asked casually: "How does your factory do electroplating?"

"What can be done, a DC generator, an electroplating tank, first grinding, then polishing, but the stainless steel strip is too difficult to do, I heard that the stainless steel strip has been plated with copper, and as a result, many finished products have been returned by customers, and the factory director is troublesome, so he changed the electroplating workshop back. Shu Hao is now full of disdain for state-owned enterprises.

Su Cheng asked in surprise, "Why do you have to plate copper?"

"It's not for the exit to make trouble. People say that foreigners like the color of copper, but how expensive copper is, so they plating copper. As a result, it can't be sold, and it is sold in China, and then it is returned and lost money. ”

"What money can be saved by copper plating on stainless steel Chapter 29 Coke and ice......"

"So. Shu Hao didn't care, he worked in the factory for three or five years, and he saw a lot of all kinds of strange things, and he saw that the strange ones were not scars.

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

"There are formulas who don't know how to do plating. After Shu Hao finished speaking, he asked suspiciously: "Where did you hear about the electroplating solution formula?"

Su Cheng smiled but didn't answer, thinking to himself, if engineering students want to answer the paper by themselves, they have to memorize two electroplating solution formulas. In fact, electroplating and Chinese medicine are almost the same, and the difference is thousands of miles. Therefore, it is necessary to continuously test different reagents and process conditions, in addition to the guidance of theoretical knowledge, accumulation is also very important.

Stainless steel electroplating is a relatively difficult electroplating method, and modern PVD vacuum coating and thermal spraying methods have been widely used, which 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 for plating.

Su Cheng thought about it, found a piece of paper, and leaned against the refrigerator to write.

Shu Hao stared with bated breath. After working in the factory for a while, all kinds of jobs will know about Coke with Ice in Chapter 29, and in his experience, this is at least an electroplating solution formula.

"70 to 90 milliliters of hydrochloric acid per liter, temperature 15 to 30 degrees, current density between 10 and 30 A. How to plating beautifully, you have to test again. Sioux handed him the paper.

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

In these years, intellectual property rights are not talked about. Especially between the public and the private, it is even more unreasonable, "the one who uses you is worthy of you" may not necessarily be said, and the facial expressions are at least in place.

Su Cheng said indifferently: "What are you afraid of, you look at the factories on the market now, which township enterprises rely on advanced technology to survive? Therefore, it is time to fight now, not the market. ”

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

"The liquidated damages should be set slightly higher than the price of the electrolytic cell. In this way, even if they learn the method of electrolyte, they are reluctant to break the contract, and would rather build a new one themselves, and the time they buy is all your profit. ”

In this paragraph, Shu Hao nodded again and again when he listened. He understands the difference in time. When I first started to make a shower, I could have a profit of nearly 100 yuan, and after half a year, the profit of a shower was at most 20 yuan. And there is a competition for showers who cut corners, and the days are getting harder and harder.

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 see that you have so many ideas, it is really better to go to the sea too." ”

This year is a prosperous year for going to the sea, and if there is no one in the unit who is on leave without pay, he will be embarrassed to say hello when he goes out.

If Su Cheng didn't have the $30,000 foundation, he might have been tempted, and now he naturally refused.

Shu Hao didn't say much, and hurriedly said goodbye to do the experiment. Whether he can start an electroplating business on his own is still two words, and his confidence is not very strong.

Sioux chuckled and continued to study the ice machine on the refrigerator.

At this time, domestic refrigerators are still sufficient, and it is not easy to work normally for a long time, and noise, energy consumption and humanization, etc., are not yet considered. For example, the habits of foreigners such as making ice and chilling are dismissed by many people as fancy.

Sioux City naturally feels different.

He's from the 21st century, and it's normal to throw ice cubes in a cola and drink fresh beer. It was also because of its convenient quick-freezing function that Sioux City decided to buy it for 3 years' salary.

If you think about it carefully, people in 87 live in a broken house, they don't have to pay a down payment and a loan, they can't save money, but they have to save money to buy electrical appliances, and the pressure on the young man's marriage is not small at all.

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

Su Cheng slammed it into a glass of water, poured a rare Coke, and a cup of Coke worth one-tenth of his salary was ready.

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

Sioux City looked over and over again, and suddenly missed the steak and sweet and sour pork ribs very much.

Beef in this era is very sought-after, and most of them are given by the leaders of the family, think about what Director Liu said when he pulled people, everyone in the Ministry of Petroleum has a big pork leg during the New Year, and everyone has a big herring to know that this kind of thing is still a rare thing, and the cattle are naturally less, as for the steak, it is even more difficult to find the cow, and I don't know where to cut it.

Sweet and sour pork ribs are not difficult, 2 yuan can buy a pound of fat meat or a pound of small ribs, if you choose the latter, the boss may also give a pair of kidneys. But Sioux City won't do it, and the restaurants in Dong*ying may not be sold. In the years when everyone ate elbows and back pot meat, ordering ribs that are not on the menu is basically equivalent to looking for ballast......

"Hey!" Su Cheng silently thought: endure it for another three years, and if there is no one to sell beef, I will raise beef cattle by myself......

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

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

"Why are you here?"

"I heard that my eldest brother said that you understand electroplating, so I thought, maybe you know something else, so I asked you for advice. Shu Lan pursed her lips coquettishly, her red lips moistened as if they had been greased, and placed a long design on the table.

"Try my homemade iced cola. Su Cheng was ashamed to put the glass in front of Shu Lan. It is not a big mistake to say that it is homemade, after all, the ice cubes in it are boiled by himself, watered by himself, quick-frozen by himself, and added to the glass by hand.

Shu Lan was already a little curious, gently picked up the Coke, and took a shallow taste, but in Su Cheng's expectant eyes, he said suspiciously: "Is it brown sugar water with ice?"

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

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

Su Cheng picked up the large scroll of design drawings brought by Shu Lan, looked at it twice, and asked, "This is a single-flow valve for an oil extractor, are you doing the design of an oil extractor?"

"Hmm. Master said that the task assigned above is to finalize more than 5 kinds of new oil extractors this year, which must have a long stroke, save electricity, and work stably. ”

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

This is a kind of pumping unit that is most widely used in the future, and it is also the one that he has the most contact with and the most widely studied pumping unit when he was in school. It wasn't until about 2000 that it became popular, and it was out of control in an instant.

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