Vulcanization of rubber is a process of improvement of the rubber elasticity and strength by heating it in the presence of sulphur. I touched upon vulcanization in our earlier posts on Autoclave and Rotocure.
A quick glance at Wikipedia will tell you that although vulcanization is a 19th-century invention, the history of rubber cured by other means goes back to prehistoric times. Thomas Hancock (1786–1865), a scientist and engineer, was the first to patent vulcanization of rubber. He was awarded a British patent on May 21, 1844. Three weeks later, on June 15, 1844, Charles Goodyear was awarded a patent in the United States.
While a picture is worth thousand words, logically a video is worth much more. Hence today I choose to concisely share with you over 1 million words in 5 amazing videos on vulcanization.
The first video of 4.49 mins is an ideal start if you are trying to get your basics right on vulcanization process and gives you a text book approach. (Caution: The slow speed and tone can be unnerving to some of you!)
The next one is a more professionally made one from ‘How Stuff Works?’ and expands the concepts of vulcanization further. This video is concise and 2.10 mins long.
The third video (3.39 mins) shows an application in the form of Rubber O-Ring Vulcanization Bonding.
Speaking of Curing and Vulcanization in rubber, it is pertinent to mention tyres. The next video is 5.17 mins long on ‘How are bicycle tyres made?’ and the application of vulcanization is just a small part of this whole process. However, it gives you the perspective to position rubber vulcanization rightly in the product manufacturing process.
With technology advancements, conventional methods are being replaced with more energy efficient and productive solutions. It is in this context, you may see the next video of a Rubber Profile Curing Vulcanizing Line. The 1.33 min video by Deguma shows a CV-line consisting of a UHF microwave channel, a hot-air channel and a infrared channel.
Did you find the fourth video of bicycle tyre above curious to explore more? Or are you a bicycling fan? Then here is a sixth video as bonus for you. Well-paced, detailed and professionally made, I found this 10.56 min video of a modern bicycle tyre and tube manufacturing from Schwalbe interesting. (Note: I am not making any brand recommendation here. However, the video is worth a watch.)
You would have spent a little less than 19 minutes if you have watched all the 5 videos on vulcanization in full. Were they knowledge-enhancing? Let me know your thoughts.
