Description
This dataset describes the calendering process of 1 kg of uncured rubber compound used in rubber product manufacturing, resulting in 0.994039 kg of calendered compound. This dataset should be used together with the dataset for 1 kg of uncured rubber compound. The data are primarily collected from the production processes of rubber conveyor belts and some other rubber products. The dataset includes auxiliary material consumption, energy use, and atmospheric emissions of the calendering process. Infrastructure such as production equipment manufacturing and factory construction are excluded from the system boundary of this dataset.
Activity Description
The calendering process mainly includes four major processes: sheeting, profiling, laminating, and coating. During calendering, rubber calenders and their auxiliary equipment are used to subject rubber compounds to compression and shear forces between rollers, producing smooth-surfaced sheets or sheets with specific patterns, rubber strips with defined cross-sectional shapes, or coating rubber onto textile fabrics and steel cord plies.
Process Description
This dataset represents the process of calendering raw materials into the desired shapes during the production of conveyor belts, hoses, plasters, and similar products.
