Silicone – an enduring industry, a sunrise industry like the sun rising at four or five o’clock in the morning. It involves a wide range of aspects, our life, the development of science and technology are closely related to it. Silicones play a key role in electronics, machinery, aviation, construction, textiles, automobiles, electricity, firefighting, medical, baby, and cosmetics.
In the past 100 years, petroleum-based production of polymer synthetic resins, synthetic rubber has brought us a colorful life of plastic, chemical fiber products, which marks the human clothing, shoes, living home is no longer completely dependent on cotton, silk, linen, wood and other natural resources. However, due to the dwindling reserves of oil after years of human exploitation, the global petrochemical industry has felt the unprecedented pressure on resources, but also the global war since World War II to now has been gunfire, and even intensified. What’s more, due to the lack of scientific use of oil in the past hundred years, due to combustion, leakage, waste and other reasons, has caused serious pollution to our living environment, resources have caused a huge waste. If we choose silica (stone, sand), the earth’s reserves of extremely rich resources to produce silicone, and use it to replace petroleum materials to produce clothes, shoes, plastic furniture, cars, buildings and other household goods, then our world will become a more beautiful new world filled with the light of human wisdom. This, is no longer a dream, she will be in the near future, with our own hands one by one to achieve! From 1863, when French chemist C. Friedel made the first silicone compound containing C-Si bond, SiEt4, to the world famous silicone giants such as Dow Corning, Wacker and Shin-Etsu. China’s silicone industry started in 1952, and today China has become the largest consumer and producer of silicone materials.
Silicone is a class of compounds composed of carbon, hydrogen, oxygen, silicon and other elements, also known as siloxane or silane, with extremely rich chemical properties and a wide range of applications.
Silicones have excellent thermal stability and maintain good physical and chemical properties at high temperatures. In addition, silicones have a stable molecular structure and are not susceptible to decomposition and oxidation reactions, so they can make full use of their chemical properties to prepare a variety of silicone materials.
The silicon-oxygen bond in the molecular structure of silicones is not easily damaged by air, moisture and ultraviolet light, so silicones have good weather resistance. Therefore, silicones are often used to make sealing materials, waterproof materials, electronic materials, etc.
Silicones do not interact with most solvents, acids and bases, and other chemicals, and have excellent chemical stability. Therefore, silicones are widely used in the electronics industry, cosmetics, medical devices, and other fields.
Silicone has good wettability and can be adsorbed by liquid and solid surfaces and form a flat, uniform and continuous lubricating film, which plays the role of lubrication, waterproof, oil-proof and anti-fouling. Therefore, silicones are widely used in the manufacture of lubricants, anti-fouling coatings, food processing oils, etc.
Silicones can be adsorbed on the surface of objects through chemical bonding and physical bonding, and therefore have excellent adhesion properties. Silicones can enhance the adhesion of coatings and materials and improve the stability and service life of products. Currently, silicones are widely used in construction, automotive, and machinery manufacturing.
Silicone has excellent properties such as thermal stability, weathering resistance, chemical stability, wettability and adhesion, and is a widely used polymer material. The application fields of silicones involve many fields such as machinery, electronics, construction and aviation, which can effectively improve the quality and performance of products and promote scientific and technological progress and industrial development.
”I’m Captain Jack Sparrow.” As soon as the words came out, Captain Jack with smoky makeup and braided hair appeared before his eyes. In the context of the era when Hollywood film and television dominate the world, Captain Jack is an explorer, a pirate, a treasure hunter, and the embodiment of freedom, bravery and desire. Of course, the reason why “Pirates of the Caribbean” has countless fans is precisely because we all know that it is nothingness and imagination, so it can properly fill the vacancy in our hearts.
Art comes from life, and imagination also has roots in reality. In the long history of mankind, there have never been no shortage of legends about treasures and treasure hunters. Sometimes lucky and sometimes unlucky, the treasure may be illusory, but it has truly nourished generations of Captain Jack, who continued to drift in the vast sea, trying to figure out the true meaning of “treasure”.
Of all the literature about treasure hunting, Rob Stevenson’s Treasure Island, based on Cocos Island in Costa Rica, is the most famous. All this stems from the robbery 200 years ago.
From the 16th century to the 18th century, Spanish colonists occupied Peru, and the Catholic Church plundered wildly throughout South America and hid the plundered treasures in Lima, the governor’s residence. In 1820, an anti-colonial rebellion broke out in Peru, and the governor and a group of clergy conspired to flee. But at that time, only one ship named “Mary” was still able to set sail, so of course, in addition to the fleeing people, the ship was also full of rare treasures that they regarded as their lives.
But when the ship passed by Cocos Island, the situation was treacherous, and the governor and his cronies fell into the water one after another. It turns out that the captain Thompson and the sailors are all pirates, planning to take the treasure of this ship for themselves through a fictional shipwreck. But the pirates did not enjoy their riches in the end, and were soon captured and hanged, except for the captain, who promised to take the Spaniards back to Cocos Island and identify where the treasure was hidden. As a result, as soon as he landed on the island, Thompson hid in the jungle and never showed up again. The legend of “Lima Treasure” has since been spread among explorers.
One of them said that in his later years, Captain Thompson handed over to a young man a list of property worth 160 million pounds and treasure maps, including a life-size statue of the Virgin Mary. In 1889, the young sailor Gilles stared at the legendary treasure map: “In the northeast corner of Weaver Bay, in a small cave at the foot of the Three Cliffs, two hundred feet behind the flood line.” wet mud.
During his 16-year treasure hunting career, Gilles devoted himself to acquiring the treasure maps of pirate descendants in the gambling caves of the port, turned the island upside down, and found 30 ducats and a pair of gold coins. Gold Gloves. Before his death in 1935, Gilles said: “I believe that there is a huge treasure hidden on that island. But if you want to find the treasure, it will take a lot of time and money. If I were young, I would start all over again.”
In 2014, Bloomberg named ocean treasure hunting the “worst investment in the world.”

In 1985, treasure hunter Mel Fisher discovered the treasure aboard the Lady Atoka
After Gilles, President Roosevelt in 1910 and Sir Malcolm Campbell, a British racing driver in 1920, all explored the island, but achieved little. Until 1931, a Belgian found the legendary golden statue of the Virgin Mary in Hope Bay on the island, and sold it for 11,000 US dollars at an auction in New York. In 2012, British adventurer Whitehead led a team of 15 multinational experts to explore Cocos Island with high-tech equipment such as robots, drilling machines, and radars, but the legendary treasure did not appear in the world.
To this day, although the Costa Rican government has already banned treasure hunting on the island in order to prevent successive explorers from damaging the ecology of the island. The legend of the “treasure of Lima” still comes and goes, perhaps confirming the words of Gilles: “It is more blessed to seek than to find, and every empty cave is proof that the treasure is elsewhere. Hope, always the mother of treasure hunters.” where the soul of the subject lies.”
real treasure island
The enduring appeal of “treasure hunting” lies in the fact that hopes are not always lost. There are indeed treasures at sea, but they are not in the island caves, but in the deep sea.
According to the statistics of UNESCO, there are more than 3 million shipwrecks in the sea all over the world. At the beginning of the 17th century, Spanish colonists opened large-scale mines in South America, plundered gold, silver and precious stones, and encountered storms and pirates on the way back to China. These wrecks became the targets of later underwater treasure hunters.
In 1953, Mel Fisher was still a diving shop owner, and he was addicted to reading “Treasure Island” after diving. It is not uncommon to dream of getting rich, but what is rare is that Mel actually did it. In 1955, he moved his family to Florida, set up a salvage company, searched for ancient Spanish shipwrecks on the coastline, and soon targeted the wreck of the escort ship “Madame Atoka” – it is said that it was a ship full of 40 tons of treasure. , the giant ship that sank on the way back from South America in 1622, known as the “Bank of Spain”.
Afterwards, the Mel family, including his wife and children, embarked on a 16-year underwater adventure. Undersea treasure hunting seems to be a costless business, but the actual implementation is costly. Mel invests about 3 million U.S. dollars a year, including the maintenance of ships, scanning devices and the salaries of 25 staff. The most important thing is that no one can tell what will be salvaged every time I go to sea. Although every time I look forward to a treasure of 400 million US dollars, the reality is likely to be a basket of shells. In the later stage, Mel even had to choose between fuel and dinner: if he went to sea, he could only catch sea fish for dinner. In 2014, Bloomberg named ocean treasure hunting the “worst investment in the world.”
But compared to money, the most painful price Mel paid was in the process of searching for the “Mrs. Atoka”, the bilge pump failed, the ship sank, and the eldest son Dirk, daughter-in-law Angel and diver Rick Gage were killed. the sea. But in the face of such a disaster, Mel did not give up, but chose to redouble his efforts to be worthy of the sacrifice of his relatives. “Today is the Day” is Mel’s motto.
It was not until July 20, 1985 that “The Day” finally arrived. The wreck of the Lady Atoka was found 22 feet underwater in a sandy area about 11 miles long and 100 feet wide—it was a real Treasure Island! The treasure on board, estimated at $450 million, included 40 tons of gold and silver, emeralds from the Muzo mine in Colombia and countless gold and silver coins. The investors and lawyers who persisted until the end, as well as the Mel family, had a wealth of wealth on that day.
But when Mel was asked in his later years why he was willing to choose this risky industry in the first place, he replied: for fun, romance and adventure.
His descendants have obviously inherited the family’s interest in exploration. In 2021, Zach Moore, the second generation treasure hunter of the Mel family, salvaged a rare ancient gold coin worth $100,000 near the wreck of the “Lady Atoka”. He said: “There is nothing like finding gold! Gold shines forever. It looks and feels exactly as it did the day it sank to the bottom of the ocean 400 years ago.”
“Black Pearl” goes to sea
Zach Moore is right. For people 400 years ago, gold was synonymous with treasure. But in another 500 years, the new treasure hunters will definitely dismiss it: what is gold! There’s nothing like finding a diamond! That’s right, under the hype of commercial brands, contemporary people’s crazy pursuit of diamonds is no less than any crazy treasure hunter in history.
On June 15, 2017, at the port of Walvis Bay, Namibia, the diamond exploration ship “mv SS Nujoma” was officially launched
In particular, Namibia, which regards diamond mining as the mainstay of its economy, used to produce more than one million carats of diamonds every year. However, diamonds, like gold, are non-renewable resources. Some experts estimate that in the next few decades, the production of onshore diamonds will decline at an annual rate of 2%. Before 2050, onshore diamond mining may come to a halt. In fact, Namibia’s formerly prosperous diamond city, Kermanskop, has become a ghost town today.
The purity of these seabed diamonds is as high as 95%, far exceeding that of ordinary land-produced diamonds, and the reserves are estimated to reach 1.5 billion carats.
Diamond companies had a sense of crisis earlier than experts. Diamonds were discovered in Namibia’s Orange River decades ago, and it was speculated that diamonds from this river may have washed up on the Atlantic seabed as well. In the 1990s, the diamond company sent ships out to explore the sea, and indeed found some diamonds in the offshore. The businessmen immediately bought 7,770 square kilometers of sea area and conducted sample experiments in the Atlantic Ocean. What is amazing is that the purity of these seabed diamonds is as high as 95%, far exceeding that of ordinary land-produced diamonds, and the reserves are estimated to reach 1.5 billion carats. This is obviously more attractive than any unwarranted treasure map.
Therefore, in 2019, a ship named “mv SS Nujoma” (the name of the founding president of Namibia) cost up to 122 million pounds, weighed 12,000 tons, and was 113 meters long. It is known as the world’s largest and most advanced diamond exploration and sampling ship The inauguration ceremony was held. It will search for diamonds at a depth of 140 meters below the sea surface. The device on board scans potential mineral sources on the seabed and excavates them. Special pipelines transport the sediment to the ship at a speed of 60 tons per hour, and then throw the diamond-free material back into the ocean. “The ship will help us maintain our current annual output of 1.2 million carats,” said the diamond company’s CEO optimistically.
But at the same time, the ecologist noted: “The waters off the coast of Namibia are rich in resident and migratory species. important areas where there is a high risk of sharks, whales, dolphins, and seals…Ocean mining uses heavy machinery to remove parts of the seabed, and habitat recovery from this disturbance can take decades.
” Like a treasure hunt, human beings harness their own courage, belief, wisdom and desire to ride the wind and waves, but at the same time must always be vigilant against being backlashed by their own desires. The treasure is in the sea, and the treasure is in the heart.
