Ultrasound in the role of renewable sources of rubber

Around the world each year to produce over 10,130 tons of waste rubber, posing a serious environmental pollution, waste rubber as a valuable use of renewable resources is of great significance. Regeneration of the rubber manufacturing methods that many, such as the oil law, water law oil, stir quickly desulfurization law, in a row from the desulfurization out of the microwave method and desulfurization law. However, they have some shortcomings. The newly emerging ultrasound desulfurization method with high efficiency, environmental protection, high quality products, has received extensive attention.

    Voice of the use of ultrasonic cavitation and a half to focus on the energy of the key elements in local areas, the local energy will be generated amazing results in the destruction of vulcanizate energy than the CC bond CS low key and key SS in order to selectively damage the rubber three-dimensional The network structure, rather than molecules bond. To this end a large number of people testing, and invented the device.

     Pelofsky in early 1973 on the use of ultrasound to the invention of the rubber to organic solvents dissolved in the device. Since then, Japanese and Austrian Tian Changxing Hatano husband Paul applied for a patent ultrasound renewable rubber, they set out in the patent, regardless of polar and non-polar vulcanized rubber, when the subject from the 500W power 50kHz frequency ultrasound generator power to issue the 20min role of ultrasound, there have been changes in the three-dimensional structure, CS bond and bond SS, and CC bond medium well and achieved the desulfurization vulcanizate. They will desulfurization after the re-vulcanized rubber, was found after the desulfurization rubber gum with similar performance, was among the first of these related to use ultrasound for the desulfurization reported that its production process is stopped.

     Lsayev the first to try to head in the extruder machine installed power ultrasonic generator to achieve continuous desulfurization RUBBER. Lsayev and his colleagues for not filling in the NR vulcanizate trial, was found in the initial phase of amplitudes increase in ultrasound, the desulfurization increase, but to a certain value, but reduce the degree of desulfurization, that is, there is a degree of desulfurization Max. The ultrasound not only because they have to explain the role of desulfurization, but at the same time there is no longer the role of sulfide. Eduardo and others of silver plastic chrysanthemum desulfurization carried out a test, the result is slightly different, they found that when ultrasound is less than 100W power, cross-linked with the ultrasonic power density increase slightly increased cross-linking density decreased. This shows that the phase of low-power, ultra-sound to enhance the increased role of sulfide.
