History of rubber
In 1826, Hancock invented the method of plasticizing natural rubber with machine white.
The industrial research and application of natural rubber began in the early 19th century.
In 1819, Scottish chemist Mackintosh discovered that coal tar could dissolve rubber. After that, people began to dissolve rubber with coal tar and turpentine to make tarps. Since then, the world's first rubber factory was established in Glasgow in 1820.
In order to make rubber easy to process, Hancock invented the method of plasticizing natural rubber with a machine in 1826.
In 1839, American Charles Goodyear invented the vulcanization method of rubber, which solved the problem of raw rubber becoming sticky and brittle, and made rubber have high elasticity and toughness. Rubber has just entered the stage of industrial application. Therefore, natural rubber has become an important industrial raw material, and the demand for rubber has also increased sharply.
During the second industrial revolution in Western countries in the 1880s, British doctor Dunlop invented the pneumatic tire in 1888.
With the development of rubber use, the British government decided to establish an artificial rubber plantation base in the Far East considering that the rubber produced by Brazil's wild rubber trees could not meet industrial needs.
In 1876, the British HA Wickham transported rubber tree seeds and seedlings from Brazil to the Royal Botanic Garden Kew in London, England, and then transported them to Ceylon (now Sri Lanka), Malaya, Indonesia and other places to plant successfully. So far, the arduous work of converting wild rubber trees into artificial cultivation has been completed.
origin of rubber
China's rubber production areas are mainly distributed in Hainan, Yunnan and Guangdong. The main rubber producing areas in the world include Thailand, Indonesia, India, Vietnam, Malaysia, China, Myanmar, Sri Lanka and other countries. Rubber is a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under a small external force. It can be restored after the external force is removed.
