Development history of china rubber

1493, the great Spanish explorer Columbus led a team to set foot on the South American continent for the first time. Here, Spaniards see Indian children and young people playing games, singing and throwing balls at each other. This kind of ball can bounce very high after landing, and it will feel sticky and smoky if it is held in your hand. The Spaniards also saw Indians coating some white sticky liquid on their clothes to protect them from rain in rainy days. Also apply this white sticky liquid to your feet so that it won't get wet in rainy days. As a result, the Spanish initially understood the elasticity and waterproofness of rubber, but did not really understand the source of rubber.

1693, French scientist Lacan arrived in South America and saw the aborigines playing with this kind of ball. Scientists and soldiers have different thinking and vision. Through the investigation of this small ball, they knew that this small ball was made of a viscous liquid from a tree called "rubber" by Indians.

1736, French scientist Kang Damin brought back detailed information about rubber trees from Peru, and published A Brief History of South America, which introduced the origin of rubber trees, the methods of collecting latex and the utilization of rubber in detail, which attracted people's attention.

1763, the Frenchman Mecca invented a solvent that can soften rubber.

1770, British chemist Priest Le discovered that rubber can erase pencil handwriting.

1823, Englishman MacIntosh, like the Indians, painted thick white rubber liquid on the cloth to make a tarpaulin and sewed a "MacIntosh" waterproof cloak, which may be the earliest raincoat in the world.

1852, American chemist guthrie accidentally dropped a jar containing rubber and sulfur on the fire while doing experiments. After heating, rubber and sulfur flow together to form a block rubber skin, thus inventing the rubber vulcanization method. Gu Deyi's accidental behavior is an important invention in rubber manufacturing industry, which removes a big obstacle for rubber application, makes rubber a formal industrial raw material from now on, and thus enables many rubber-related industries to flourish. Subsequently, guthrie made the world's first pair of rubber waterproof shoes with vulcanized rubber.

From 65438 to 0876, an Englishman named Wei narrowly escaped death. He collected 70,000 rubber seeds from the tropical jungle of the Amazon River, sent them to the Royal Autumn Botanical Garden in London, England for cultivation, and then transported the rubber seedlings to Singapore, Sri Lanka, Malaysia, India and West Asia for planting, and achieved success. By 2004, natural rubber/KLOC-0 has been successfully planted all over the world for 28 years.

1888, an Englishman, Deng Lubian, invented pneumatic tires, and began to produce cars in 1895. The rise of automobile industry has aroused great demand for rubber, and the price of rubber has soared.

1897, director of Singapore Botanical Garden.
