Great Power Ship

Chapter 211 One-stop Service Provider

"Oh? Are you talking about our JJZ-110B vacuum shot peening derusting machine?" Wen Dawei asked with some uncertainty.

"Yes, it's a vacuum shot peening machine..." Captain Mahathir nodded quickly: "I didn't expect you to even have this thing. You know, it's a standard configuration for large shipyards..."

When he said this, Captain Mahathir took a meaningful look at the not-so-spacious but orderly factory building, as if to say that he really did not expect such a small factory like yours to have such a high configuration.

It is not wrong to implement what Captain Mahathir said. Rust removal is an important process that cannot be avoided in the field of shipbuilding. Whether it is the maintenance of old ships or the construction of new ships, due to material and environmental issues, The cabins and plates on many ships will be oxidized and rusted.

And this kind of corrosion has great disadvantages for welding and other processing, so how to remove it has become an essential skill for shipyards.

The traditional method is to manually polish off the oxide layer on the surface, not to mention the labor-intensive operation. Due to the limitation of labor, the details of the treatment are not satisfactory. If it is a general extensive processing, it does not matter. If the precision requirement is high, such a method is difficult to implement.

So there is a rust remover prepared with chemical reagents. Apply this thing on the surface of the board. After dilution, rub it with a brush or other tools. No matter it is rust or paint, it can be wiped off, and it can penetrate into any surface. There are no dead ends in the subtleties.

However, such a method is not only harmful to the human body due to the large number of harmful substances in the chemical reagents, but also causes great environmental pollution.

Although these two methods have many disadvantages, the overall cost is low, so many small and medium-sized shipyards favor them.

Especially in some shipyards in developing countries, the labor cost is low, and there is not so much emphasis on labor security. Therefore, these two derusting processes can be seen everywhere in the shipyards of these countries.

Not to mention anything else, South Korea's shipbuilding industry is a big player in the application of these two derusting processes.

Anyway, as long as they make money, the life and death of the South Korean boatmen is simply not within the scope of consideration of the current South Korean chaebols.

The craftsmanship that is common in developing countries is different in Europe and the United States. Due to the high labor costs, the awareness of value and environmental protection is deeply rooted in the hearts of the people.

In the late 70s, the shipbuilding industry in developed countries in Europe and the United States completely eliminated these two rust removal processes that required manpower and environmental costs.

It has been replaced by a purely physical property and a completely environmentally friendly vacuum shot blasting derusting process.

That is to use steel balls or special sand particles with a diameter of only a few millimeters or even a few microns to hit the surface of the board under the push of high-pressure gas, thereby completely peeling off the rust or paint on the surface of the board.

Because of its high efficiency and environmental protection, this process has been widely used in the manufacture of warships and submarines by developed countries in Europe and the United States, and even some high-end luxury yachts, large-tonnage container ships and other civilian ships also use this process.

Not only that, due to the excellent performance of this process, it is even adopted by some vehicle repair shops.

For example, the U.S. military special vehicle repair plant in Arizona, USA, purchased one such vacuum shot peening derusting machine for the refurbishment and maintenance of the U.S. military's M60 main battle tank and M113 armored vehicle.

However, this kind of equipment is good, but the price is very impressive. There is no way that all related manufacturers are concentrated in European and American countries.

Often a lion can tear off a piece of meat by opening its mouth wide.

Not buying?

Yes, but such high-end ships as luxury yachts, offshore oil drilling platforms, advanced engineering ships, LNG oil liquefied gas ships and so on are out of your reach.

why?
Because you are not environmentally friendly!Because you didn't give the boatmen the labor protection they deserved!

What?Will this cause your own costs to rise?
The developed countries don't care, because their standards are full of love, for the sake of world peace and human development!
So, you don’t have to, sorry, you will never get a series of high-end shipbuilding orders with the highest profit margins, even if the top iron is useless, because the authoritative classification societies in the world are all in the hands of developed countries in Europe and the United States.

Even if the technology is as strong as that of Japan, it will be based on the standards of Europe and the United States, otherwise it will be beaten, let alone other developing countries.

Because of this, this kind of vacuum shot blasting derusting machine is basically the symbol of a large shipbuilding factory in this three-acre area in Asia, because only a large factory has the strength to equip such high-end equipment that is ridiculously expensive.

But now, the Zhujiang factory, which has just been established and has not even launched a ship, actually has such a symbolic thing of a big factory, which makes Captain Mahathir take a high look at the technical strength of Zhujiang factory. I can't help feeling the ambition of Zhujiang Factory.

It is estimated that it will not be long before this little-known Zhujiang shipbuilding plant can rise into a well-known ship repairing plant in Asia.

Thinking of this, Captain Mahathir asked: "Where did you buy this vacuum shot peening equipment in Europe? England or Germany?"

Hearing this, Wen Dawei couldn't help being stunned for a moment.

When Mahathir Shipyard saw this, he thought he had guessed wrong, and quickly added: "Could it be France? Of course, the Swedish ones are also very good. I have seen Swedish products in the Norwegian ship repair yard again, and the efficiency is not as good as that of Germany. The difference... um... none of it, that's..."

Just as Mahathir was talking, Wen Dawei smiled lightly and shook his head. Captain Mahathir frowned, and when he was about to turn around and ask if it was an American product, Wen Dawei smiled all over his face. Pointing to himself: "It is a product developed by ourselves, and it is divided into two types. One is this mobile JJZ-110B vacuum shot blasting derusting machine, and the other is..."

Wen Dawei pointed to the end of the factory building, a metal frame with a height of four meters, like two elevator towers put together: "That is our JJZ-110C vacuum shot blasting derusting machine, which is mainly used for large ship decks. Rust removal and surface treatment, of course, the price difference between the two is also very large. The cheapest JJZ-110C vacuum shot blasting rust remover is 400 million US dollars; while the JJZ-110B vacuum shot blasting rust remover is only 15 US dollars.

The functions are similar, but the JJZ-110B vacuum shot blasting derusting machine is more suitable for small parts such as the stern shaft seal sleeve, and requires manual operation, but it is relatively flexible; the JJZ-110C vacuum shot peening derusting machine is It is more suitable for large plates or complex structural parts of more than 10 tons. It has general flexibility, but it is a fully automatic equipment controlled by computer.

All in all, each has its own merits, how about it?Is Captain Mahathir interested in purchasing a batch to go back and try? "

Captain Mahathir was stunned when he heard the words, and asked after a while: "Are you still making equipment?"

"Look at what you said..." Wen Dawei laughed: "I told you when you just got off the ship, our Zhujiang factory is a one-stop service provider in shipbuilding, so professional equipment in shipbuilding, of course we It's being produced!"
