Now that you get a free thug for nothing, why not do it?

"Hahaha, then it's settled. I'm going to help these people pack boxes quickly."

Sun Dasheng ran to the ship with a smile, sat on the bow, and used magic spells to see these containers being quickly loaded onto the ship.

Lin Tian smiled. Fortunately, he has already bought this place. The people under his command are special soldiers who have undergone special training and have top-notch confidentiality capabilities. They have a certain ability to accept these unreasonable things. The secret here will not be revealed.

Li Changsheng and Wang Shijiu are in charge of managing and running the operating systems of these AGV robots remotely, and the warehouse handling AGV robots are also quickly packing their brothers into containers.

Get ready to fend off here with the fastest form of online shopping, loaded on board.

The reputation of China's infrastructure madman is now known to everyone. Various long-span bridges, long-distance railways, super-large seaports, and huge offshore platforms have all made great contributions to China's economic development.

But if you look closely, the steel on these infrastructures is often rusty and looks dilapidated, which makes Monkey King very worried, and he thinks it is not safe.

"Actually, you don't have to worry at all. These facilities in our country use a special kind of steel—weathering steel."

"Ordinary steel contains some impurities, the activity of these impurities is relatively low, and the rust that will accelerate the production is a loose and porous structure with many cracks. In this way, the rust is like a sponge, which can continue to absorb moisture in the air, allowing The steel corrodes further, and it will be more dangerous if it encounters strong corrosive substances. The certain bridge in India is often used as a spittoon by the locals, and the local residents like to chew a tobacco product that teaches Gutkha, resulting in strong acidic substances in the saliva, which has accumulated over the years Over the past few months, the steel pillars of the bridge have been corroded and almost turned into a dangerous bridge."

"my country's annual loss due to metal corrosion also accounts for 4% of GDP. The annual loss of steel due to rust in the world even accounts for as much as a quarter of the world's annual output. It can be seen that rust prevention of steel is as important as production, and weather resistance Steel is different from normal steel."

"Weathering steel, that is, atmospheric corrosion-resistant steel, is a low-alloy steel series between ordinary steel and stainless steel. Weathering steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It has the toughness and toughness of high-quality steel. Plastic extension, forming, welding and cutting, abrasion, high temperature, fatigue resistance and other characteristics; weather resistance is 2~8 times that of ordinary carbon steel, and paintability is 1.5~10 times that of ordinary carbon steel. At the same time, it has rust resistance, making Components have the characteristics of corrosion resistance, life extension, thinning and consumption reduction, labor saving and energy saving. Weathering steel is mainly used for steel structures exposed to the atmosphere for a long time such as railways, vehicles, bridges, towers, photovoltaics, and high-speed projects. Used for manufacturing containers, Structural parts such as railway vehicles, oil derricks, seaport buildings, oil production platforms, and containers containing hydrogen sulfide corrosive media in chemical and petroleum equipment."

"Refers to the low-alloy structural steel that has a protective rust layer that is resistant to atmospheric corrosion and can be used to manufacture steel structures such as vehicles, bridges, towers, and containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only trace amounts of alloying elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc., and the total amount of alloying elements only accounts for a few percent, unlike stainless steel, which reaches [-]%. Ten percent, so the price is relatively low."

"It not only has the strength and willfulness of ordinary steel, but also has a lifespan of more than 80 years. At the beginning, it will rust on the surface like ordinary steel, but at the same time it will also form an airtight sealing layer. , so weathering steel has a set of natural protective clothing. Leverage strength to protect the steel itself."

"Nowadays, a large number of offshore platforms, oil derricks, seaport buildings, sea-crossing bridges, containers, and long-distance railways in China are constructed of weathering steel. Although the price is higher than ordinary steel, the maintenance cost is less than half. An environmentally friendly and efficient building material."

"In addition, weathering steel is favored by architects due to its full post-modern aesthetics. Many landscape sculptures, observation decks, bridges and passages in many scenic spots are also constructed with weathering steel. It looks full of history. sense, and a steampunk violent beauty."

"The Yanxi Lake Campus of the University of Chinese Academy of Sciences has built such a central building with a weather-resistant steel exterior."

"The Luxembourg Pavilion and the Australia Pavilion in the 2010 China World Expo were also constructed using weathering steel."

"It is said that these weathering steels can be 100% recycled after the exhibition. Although my country's weathering steel industry started later than European and American countries, my country has added copper and phosphorus through technological innovation, and mixed titanium, rhenium, etc. China's production is abundant Metal elements, while improving the quality. The cost has been reduced by more than half, and it has gained the advantage of rolling in the international market.”

"Today, China has become a major country in the production and export of weathering steel. Especially in the field of bridge construction, China's weathering steel can meet the high strength, high plasticity and corrosion resistance required by steel for long-span bridges. Respond freely in various polluted environments.”

"Information, materials and energy. Known as the three pillars of contemporary civilization. Among them, materials are the material basis for human survival and development. The material that has the greatest impact on modern society is steel."

Just as Lin Tian was learning about this aspect of knowledge with Monkey King, a secret phone call came through Lin Tian's cell phone.

"Hello?" Lin Tian picked it up and asked the other party in a puzzled tone.

"Lin Tian, ​​what do you want to do recently? I heard that you have bought a lot of things recently." On the other end of the phone is the voice of the old man from Zhonghua and Long District. It is very famous that he has collected Lin Tian these days Information about what you did.

"Women's clothing/underwear, men's clothing/sports and outdoors, women's shoes/men's shoes/bags, beauty makeup/personal care, watches/glasses/jewelry, mobile phones/digital/computer office, mother and baby toys, snacks/tea wine/imported food , fresh fruits, major appliances/living appliances, furniture and building materials, automobiles/accessories/supplies, home textiles/furniture decorations/flowers, medicine and health care, kitchen utensils/storage/pets, books and audio-visuals."

"What do you want to buy so many things, boy? Rebellion? Or escape Noah's Ark?" The old man shouted at Lin Tian excitedly.

"And you got so much money from you kid. The transaction volume of your purchase of these supplies alone has reached 1682 billion yuan. I heard that you also bought gantry cranes? AGV intelligent robots? There are also several ships above 2000 tons The giant container ship? All of these add up to at least 3000 billion, [-] billion yuan or more, right?"

　I really don’t know how to write old books, and now I’m basically just scribbling, trying to make up the number of words.Let's read the new books, everyone. I'm just using the old books for the subsistence allowance.
