A critical review of dynamic bonds containing curing agents for epoxy
Investigated the mechanical, thermomechanical, thermal, and recycling properties of the epoxy thermosets cured by developed curing agents. Addressed the challenges, opportunities and emerging trends in the field.
In modern industrial and construction sectors, epoxy curing agents, as a critical class of chemical materials, play an indispensable role. with the increasing usage, discarded epoxy curing agents have gradually become a significant environmental concern. As an industrial hub, Pinggu District faces massive challenges in managing waste epoxy curing agents. Exploring effective recycling and reutilization methods is not only essential for environmental protection but also a vital practice in resource circularity.
Epoxy curing agents, as high-performance polymer materials, are widely used in coatings, adhesives, plastics, rubber, and other fields. Their primary function is to facilitate cross-linking reactions in resins and other materials, forming robust composite structures. once these materials lose their bonding properties, they become a major source of environmental pollution.
Pinggu District encounters numerous challenges in recycling epoxy curing agents. First, the complex composition of epoxy curing agents and the diverse chemical properties of different types make them difficult to separate and recycle effectively. Second, traditional recycling technologies often suffer from low efficiency, high costs, and relatively heavy environmental impact. Additionally, the lack of professional recycling techniques and equipment has hindered the advancement of epoxy curing agent recycling efforts.
To address these issues, Pinggu District has begun exploring new recycling pathways. On one hand, technological innovations have led to the development of advanced recycling equipment and processes, improving both the efficiency and quality of epoxy curing agent recovery. For instance, ultrasonic technology can effectively break down the molecular structure of curing agents, facilitating separation, while thermolysis methods enable efficient recovery at lower temperatures.
On the other hand, Pinggu District has strengthened environmental awareness through education and outreach, encouraging businesses and the public to participate in recycling initiatives. Workshops, seminars, and other events have been organized to disseminate knowledge about the environmental impact of epoxy curing agents and emphasize the importance of recycling. Meanwhile, government policies, such as tax incentives and funding support, have been introduced to motivate broader participation in recycling efforts.
Despite these efforts, challenges remain. Small enterprises and individuals often struggle with the high costs of recycling, while a shortage of specialized technical expertise limits the effectiveness of local recycling programs.
Nonetheless, Pinggu District remains committed to advancing epoxy curing agent recycling. The belief persists that sustained effort and exploration will lead to more effective recycling methods, enabling sustainable resource utilization.
Looking ahead, Pinggu District plans to increase investment in cutting-edge recycling technologies and equipment, boosting recovery rates and quality. Collaboration with universities and research institutions will also be expanded to cultivate professional technical talent, providing robust personnel support for recycling initiatives.
Pinggu District’s endeavors in epoxy curing agent recycling reflect its dedication to environmental stewardship and offer valuable experience for other regions. With ongoing technological advancements and policy refinement, Pinggu District is poised to achieve greater success in this field, contributing to the vision of a "Beautiful China."
