The world's problem of the two pollution of reclaimed rubber production has been successfully cracked
![]()
In August 6, 2015, the reporter went to interview Jiangsu Qiangwei Rubber & Plastic Technology Co., Ltd., in an annual output of 5000 tons of particle regenerated rubber continuous production workshop not only did not smell the pungent odor, also did not see white smoke emission. Zhu Jun, President of the association, at the scene of the production to the reporter said, reclaimed rubber production of green door was finally knocked, and realize the change of this breakthrough technology called multi order screw continuous green desulfurization of particle regenerated rubber sets of technology and equipment were prepared by China's tire recycling.
The project lead Zhang Liqun, a professor of Beijing University of chemical industry told reporters that the project for "12th Five Year" national "863" project, led by the Beijing University of chemical technology, combined with Jiangsu Qiangwei Rubber & Plastic Technology Co., Ltd. jointly completed. Project group aiming at the shortcomings of the traditional waste rubber desulfurization system for preparing regenerated rubber technology pollution large, high energy consumption, safety, product quality and unstable, the first double screw dynamic continuous desulphurization and screw dynamic continuous shear lower Mooney viscosity of linkage technology, realized from the powder to reclaimed rubber in the preparation process of the green, energy-saving, continuous and efficient production, reached a near zero emissions. Moreover, the technology is more suitable for the recycling of waste rubber resources such as high performance tire recycling rubber, Ding Ji rubber, ultra low viscosity liquid rubber, etc..
Over the past few decades the global scope has not been achieved in the production of renewable rubber production "near zero emissions", is how to come true? Zhang Liqun said, technical formulation of using the technology of desulfurization equipment is not used in the water and under the condition of sealing completed powder for preparing desulfurized rubber powder heating and cooling process, from the source to solve the traditional high temperature regeneration in rubber production process of water pollution and air pollution problems, lower Mooney viscosity link is in closed under the condition of low temperature and improve processing performance of desulfurized rubber powder, preparation (particles) rubber regeneration process, so as to solve the traditional open refining machine high temperature and strong shear caused by air pollution problems.
According to the Suqian City Environmental Protection Bureau of the monitoring results show that, Qiangwei regeneration air quality in the vicinity of the rubber plant comply with the requirements of environmental protection, the production of particles are regenerated rubber performance good and stable, testing by the authority, reach and better than regenerated rubber national standard GB/T13460-2008 the requirements.
According to reflect the Linglong tires, Aeolus Tyre, Wuxi Baotong belt industry company, using the process in the production of granular recycled rubber products excellent performance and stability, Mooney viscosity small rebound to solve the tradition of massive reclaimed rubber downstream applications when mixing is difficult to disperse, high energy consumption, Imeni scorch problem, with high efficiency and low consumption application in rubber product processing. At present, the use of the process of production of granular rubber tire and full steel radial truck tire has been successfully developed.
According to reports, in addition to the "near zero emissions", the technology in energy saving and safety also great advantages, energy consumption the tons of products is equal to or less than 650 kwh, compared with traditional process, the reduction of about 20%; and the there is no traditional reactor with high temperature and pressure of high risk and high speed open refining machine operator's dangerous and harmful gases on the operation of the workers health hazards such as security risks. Full automatic control, also let by the number of workers reduced to a quarter of the traditional process. At present, the first international technology has 13 patents for invention, and from Nanjing Green Jin rubber Tech Co., Ltd. organized industrial equipment manufacturing. In addition to the Jiangsu Qiangwei Rubber & Plastic Technology Co., Ltd., Beijing Luther Yongtai Environmental Protection Technology Co., Ltd. and Hangzhou Zhongce Rubber Recycling Technology Co., Ltd., Guangdong collar Grid Resources Regeneration Technology Co., Ltd. is in the application of the technology of production line construction.
