On June 27th, the China Federation of Logistics and Purchasing organized experts to identify the scientific and technological achievements of the energy-saving and environment-friendly waste rubber series cooling dynamic desulfurization technology for Jiangsu Qiangwei Rubber & Plastic Technology Co., Ltd. The appraisal committee believes that after six months of production and operation, the technology has high performance and stability, especially in terms of quality improvement, consumption reduction, energy saving and environmental protection. It is the first in China and the key technology has reached the international advanced level.
The new technology of energy-saving and environment-friendly waste rubber series cooling dynamic desulfurization is jointly researched and developed by Jiangsu Qiangwei Group, Huainan Petrochemical Machinery Equipment Co., Ltd., Beijing University of Chemical Technology and China Tire Resources Recycling Research Center. After testing, the recycled rubber produced by this technology meets and exceeds the requirements of the current national standard (GB/T13460-2008), the user reflects well, and the economic and social benefits of the technology are significant. According to the environmental monitoring department, the ambient air quality of the technology production meets environmental protection requirements.
According to Prof. Cheng Yuan, Director of the Appraisal Committee and Director of the Technical Committee of the China Tire Renovation and Recycling Association, the current domestic recycling rubber industry generally adopts the traditional intermittent production process, which has high energy consumption and high pollution, and has become a serious constraint to the development of the industry. Compared with the traditional process, the main innovation of the new technology of waste rubber series cooling dynamic desulfurization is reflected in: the tank cooling technology reduces the temperature and pressure of the recycled rubber after desulfurization, and no waste gas or waste water is discharged. The technology solves the problem that the rubber material is sticky, easy to block and difficult to clean, reduces the water addition amount of 80%-90% in the formula, improves the production efficiency, and has remarkable effects of energy saving, consumption reduction and environmental protection. The 18-channel intelligent instrument + contactor control mode technology extends the fatigue life of the tank material and the maintenance cycle of the entire equipment, improves the safety of the electric heating system, saves energy and reduces consumption, and improves the stability of recycled rubber products.
It is understood that the key point of the production process of recycled rubber is desulfurization and reduction, and the commonly used coal tar with low cost and excellent performance is the "culprit" that pollutes the environment and odors disturb the people. If you pass this process
Dissolving the stench and other environmental problems will help the reclaimed rubber industry to remove the "pollution cap". Ji Kuijiang, a member of the appraisal committee and a professor at Qingdao University of Science and Technology, said: “Environmental pollution is the main bottleneck in the recycled rubber industry. If the problem is not completely solved, the industry will not be able to survive, let alone develop.†The new technology of waste rubber series cooling dynamic desulfurization R&D will provide technical support for the recycling rubber industry to solve environmental pollution problems.
