Whats Rubber-Rubber tyres but what is it?
Rubber is one of those everyday things that we take for granted. We all use things made of rubber in our daily lives. In my case, I see large things made of rubber, namely tyres. Most of the Worlds rubber is manufactured from a white runny substance that is extracted from trees in huge rubber plantations that are grown in the tropical regions of the World. The white substance is called Latex and is obtained from the small trees from slits in the bark that allow the latex to run into collecting cups. These cups are then poured into bigger vessels and collected. The collection of the latex is very labour intensive and requires thousands of people to work in the vast forest plantations that stretch for mile after mile covering many acres.
This simple process marks the beginning of making tyres and all other Natural Rubber products. The latex has to move to storage factory facilities very quickly as it soon sets to a solid from its runny liquid form when it is extracted from the trees. The rubber is then split up to be used in separate products.
When the latex is in the process, of being moved. Such as during transportation. An amount of Ammonia is added which stops the latex from setting, before arriving at the factory for processing. When the rubber reaches the plant, it is allowed to set into sheets and is cut to size for shipping. It is often referred to as “Gum Rubber”.
Way, it is necessary to mix the gum rubber with other chemicals.
These are usually sulphur and peroxide or bisphenol. This mixture improves the resistance. Preventing the dough from perishing. This process is known as Vulcanisation. Naturally, was seen as pioneering work by Charles Goodyear back in 1839. He also used carbon black. Hence, to improve the strength of the rubber mix that is necessary for the manufacturing of rubber tyres. Making tyres is a very complicated process of mixing the right chemicals and always needing and heating the rubber mixture using huge machines and would require another article, but I still think it is amassing how a tyre starts out in a rubber plantation as a white liquid and ends up like a tyre.
Creating rubber in the tyre factory is carried out in several ways. Extrusion is one of the most common methods used this is when the rubber is heated and passed through large rollers to mould the rubber. The rubber is then heated and the forced at high pressure through a small hole this method can produce long strands of rubber. Another method of creating rubber is compression moulding. This is done under heat and pressure, however, this time the rubber is heated in a mould. The rubber is then left to cool in the mould, and the rubber creates a replica of the mould. The final way of which rubber can be moulded is a method of injection moulding. This is achieved by heating rubber again which is then injected into a mould and cooled to create the ultimate product tyres.
