The self-leveling ground is made of cement and a mixture of plastic and pigment, this time and space does not have this kind of material and technology, Li Yixuan can only go to another time and space to find it, but he did not simply buy the material and finish, he also bought it together with the technology, although there were some twists and turns in the middle, and a lot of money was spent, but he thought it was all worth it.

The constant temperature air conditioner is composed of a temperature sensor, a rectifier circuit, a control chip, a servo motor, and a compressor. Among them, servo motors are available in this time and space, but they are controlled products. It cannot be produced domestically.

As for the CPU chips, forget it, the chips of this period are just like that, let's go to another time and space to procure. Anyway, if you use it yourself, it doesn't matter if it's super or not. It's a big deal to strengthen the management of the factory and not let unrelated personnel come in, especially in key areas, and unrelated employees can't go in.

In fact, you have seen a factory like the People's Park, where you can enter and exit when you want.

Li Yixuan thought about the difficult things in his mind for a while, and then arranged the specific things. Servo motors are the most difficult to do, although Hong Kong is not a controlled area, it is too close to the mainland.

Westerners are not fools, as long as they have the heart, they can know that Chinese mainland will not give up Hong Kong, so Hong Kong has virtually become a control zone that is not a control zone.

Forget it, let's go to another time and space to buy it, and by the way, buy the production technology too. As for whether to produce or not, and when it will be produced, it depends on the situation. Li Yixuan is not a brainless person, he has to find a place to produce.

Epoxy resin self-leveling ground, Li Yixuan set up a laboratory at the construction site at zero hour, with formulas and technologies, which he specially selected, and they can be produced by using raw materials in this time and space. Of course, in terms of technological advancement, it must not be comparable to that time and space.

Hardly any advanced equipment was used, and several experiments were done, and it took two days to prepare a qualified epoxy resin paint. However, the amount needed was very large, and Li Yixuan didn't have the heart to build such a factory, so he found a company in Hong Kong to build an OEM. However, he controlled the additive technology in his hands and did not hand it over to the OEM factory. Without Li Yixuan to provide additives, the other party couldn't produce it even if he wanted to hide it.

All the materials are in place and you can start the interior decoration. The shock absorption technology of the mechanical base is handed over to the robot engineer, and it is adjusted little by little until it is qualified.

Epoxy resin self-leveling ground is dry-mixed, so it can leave in a few hours. It is very convenient, and because it is added with plastic and artificial rubber, it has a certain anti-slip and shock-absorbing effect.

Constant temperature air conditioning is a big trouble after continuing the servo motor. Its control system must collect data for a long time to make a small database, which involves system integration and database technology. Therefore, it is necessary to use microcomputer databases and software engineers to make software, and debug it little by little. In desperation, Li Yixuan bought several medium-sized computers from HP and designed his own enterprise database with reference to Oracle's enterprise database system.

Air purifiers can also be bought in this time and space, because the hard disk does not have high requirements for the cleanliness of the plant, there is no need for a very high-end air purifier, the general enterprise level is OK, and the price is relatively cheap, and finally Li Yixuan chose an air purifier produced by a Canadian company, and the installation and commissioning was completed in less than a week.

On the contrary, the control system and enterprise database have been tossed back and forth for nearly half a year. But in the end, it was successful, not easy! These factories are currently the most advanced factories in the world.

The plant has been completed, and the beautification of the outside environment and the hardening of the road surface have already been completed. This is the only garden-style factory in Hong Kong, with a black marble pedestal and a powerful "Oranges memory Inc." inlaid with a stainless steel water chestnut angle. As well as a large full-color orange logo, Li Yixuan's heart is full of great sense of achievement, this is his own factory.

The factory gate is made of stainless steel with an electronically controlled telescopic door, which is 20 meters wide. This kind of electronically controlled telescopic door has not yet been made in this time and space, not that it cannot be done, but everyone is generally accustomed to the traditional large iron door.

Therefore, Li Yixuan downloaded the design drawings of a stainless steel retractable door from the 23rd century Internet and handed it over to the factory here to manufacture.

The entire factory is very modern from the inside out. In the entire industrial area of Hong Kong, it stands out from the crowd and stands out.

Li Yixuan was not dissatisfied, not to mention the feelings of people like Cao Yajing, Guo Yifei, Peng Bin and other people who met him for the first time, which was very visually stunning. Even in the future generations, it is top-notch, and only a few top electronic technology companies can reach or surpass.

This is the world's first steel structure workshop, creating many world firsts, constant temperature and humidity, ultra-clean air purification, all-steel frame structure design, color steel tile, electronic telescopic door, top shock absorption technology, etc. In addition, there is a large drainage and sewage system that runs through the entire plant underground.

This place is close to the sea, Li Yixuan doesn't want a typhoon or a heavy rainstorm to flood this place, so he doesn't dare to have any sloppiness in the drainage system. All of them are designed according to SD Jinan's large underground drainage system. The amount of work is a bit large, with the function of rainwater and sewage separation collection and recycling, it has not been fully completed, only part of it has been done, and later with the expansion of the production area, this drainage system will be extended, but the current system is enough.

Li Yixuan waved his hand and directly held a celebration banquet in the factory canteen. The dishes were all ordered from the hotel in Yuen Long and sent directly to them.

After the plant is built, it is about to start production, the equipment is debugged one by one, the workers are also recruited and trained, and with Li Yixuan's order, the factory began the first trial production.

The first to start is the base factory and the magnetic head factory and the permalloy powder core processing plant, the polycarbonate was originally melted in the vertical high-temperature furnace, and then the glass fiber was added according to the proportion, melted and stirred, and then added specially configured additives, Shaoqing a long transparent cylinder with a diameter of 3.5 inches was pulled out, and after the cooling zone was completely cooled, the engineer began to test it.

It took nearly an hour for the final result to be reached, and all parameters were up to standard, and they were all of the highest standards.

Li Yixuan smiled, more than 9 months of hard work was not in vain, and the first step was successful.

Then it is cut, not too thin, not too thick, cut thick is a waste, cut thin will destroy the physical properties of the plate base, it will become a waste product, recast and recast.

In order to ensure the quality and minimize the mistakes, the cutting of the plate base is completely automatic cutting, here we must not consider whether the equipment is too advanced, in fact, it is completely redundant, the technical content of this cutting equipment is not superb, in addition to the control chip on the control system, all the parts can be bought in this time and space, the only difference is that the price of the parts is a little more expensive.

The biggest advantage of using the plasma cutting process is that it does not damage both sides of the disc base in the slightest.

This acetate fiber glass rod excised a total of 1,000 disc substrates. After the cut disc substrate has passed the inspection, it is placed on an automatic conveyor belt and sent to the grinding area for surface grinding. The surface must be sanded very smooth.

The polished disc substrate, under the irradiation of the sun, reflects the colorful brilliance, and there are layers of halos outside the brilliance, which are full of three layers.

Looking at these three layers of halo, even people who don't understand it understand that this is the performance of a superior product.

Put it to the electron microscope for testing, sure enough, all of them are qualified, and all products are excellent.

At this time, the first batch of permalloy powder cores processed at another factory had been processed, and workers drove forklifts to deliver the disc substrates and permalloy powder cores to the coating shop.

Once the ingredients are inserted, the machine starts applying them automatically. After a while, the smeared disc substrate is sent to a low-temperature oven of up to 160°C to bake, using a conveyor bake, which enters and exits at the same time, and comes out in less than 30 seconds.

Then there was another test, but this time it didn't go so well, and a third of them failed.

Li Yixuan frowned, and the engineer carefully searched for the reason, and finally shortened the baking time to 26 seconds.

Another test, this will be successful, all the discs are qualified, but the engineer is still not satisfied, this batch of finished discs can only be regarded as qualified, not excellent, have to continue to debug, after more than 30 times of debugging, finally all reached the excellent quality.

So far, the trial production of the platter has been a complete success.

But now is not the time to celebrate, only when the complete hard drive is of good quality can it be considered a success.

At this time, Li Yixuan turned his attention to the production of magnetic heads.

When the discs are produced, the production of the head in the factory on the other side is carried out at the same time.

The production process of the magnetic head is much more complex than the platter, and it is the largest, most complex, and most technical production area in the entire hard disk factory, but also the production workshop with the least number of workers. There is no way, in order to ensure the production quality and production efficiency of the head, Li Yixuan has used too much advanced equipment here, but there is no equipment in this time and space, except for a few monitoring personnel, the production of the entire head is unmanned.

Li Yixuan waited for two hours before the first batch of qualified reading and writing heads was produced. Due to the advanced equipment used, the production of magnetic heads is the smoothest, although there are many processes. All heads are qualified and of excellent quality.

Finally, enter the most critical stage, the hard disk assembly workshop.

When he came to the assembly workshop, Li Yixuan received a notification from the doorman that Guo Taiming was coming.

Li Yixuan smiled, turned to Cao Yajing and said, "Business has come to the door." ”
