What are the hazards of waste rubber and how can they be used for regeneration?
The disposal of waste rubber is one of the serious problems facing people today. In order to meet the requirements of materials to improve the performance of rubber, towards high strength, wear resistance, stability and aging resistance of the direction of development, but also caused a long period of rubber not biodegradable waste after a large number of waste rubber, causing than plastic pollution (white pollution) more difficult to deal with the black pollution. On the other hand, precious rubber resources are wasted.
In addition to piling up waste rubber products as fuel burning, scientists have been studying more effective waste rubber regeneration technology since 1910. Reclaimed rubber refers to the physical and chemical processes such as comminution, heating and mechanical treatment of waste vulcanized rubber, which can change from elastic state to vulcanized rubber with plasticity and viscosity. The essence of the regeneration process is the comprehensive effect in heat, oxygen, mechanical function and recycling agent of chemical and physical functions, make the network vulcanizate degradation, the fracture position of both crosslinks, also have large molecular cross-linking bond between. Rubber regeneration methods can be broadly divided into two categories: physical regeneration and chemical regeneration.
Every year, millions of tons of waste rubber are produced in the world, and the quantity is so huge. How to deal with them effectively has become a common concern of the whole society.
