Description
This dataset describes the vulcanization process of 1 kg of uncured product, yielding 0.988991 kg of vulcanized product. This dataset should be used together with 1 kg of raw material. The inventory data were compiled from multiple sources, drawn from the production processes of rubber conveyor belts and some other rubber products. The dataset includes major raw and auxiliary material consumption, energy use, and atmospheric emissions during the vulcanization process. Infrastructure such as production equipment manufacturing and factory construction is not included within the system boundary of this dataset.
Activity Description
Vulcanization refers to a process in which semi-finished rubber products, made from rubber compounds (such as raw rubber, masticated rubber, or mixed rubber) possessing certain plasticity and viscosity and processed appropriately (e.g., calendering, extrusion, molding), are transformed under specific external conditions—via chemical means (such as a vulcanization system) or physical means (such as gamma radiation)—into soft elastic rubber products or hard rubber products, thereby acquiring their desired service properties.
Process Description
Rubber vulcanization is one of the main technological processes in rubber product manufacturing, as well as the final processing step in rubber product production. During this step, rubber undergoes a series of complex chemical changes.
