| dc.description.abstract | PT. Industry Karet Nusantara (IKN) is one of the companies which process rubber
into several products, one of which is the Conveyor Belt. For these products must
meet the standards of hardness at 65 ± 5 Shore A.
Then have done research on the effects of carbon on one physical parameter Conveyor
Belt was hadrness. Variations of carbon used was 3kg, 4kg, 5kg, 6kg, 7kg, 8kg and
9kg with vulcanization time for 60 minutes and the temperature vulcanization used
1400C. Observed physical properties of the rubber compound is hadrness. This
treatment was obtained from the relationship between the variation of the carbon was
directly proportional to the force. If the amount of carbon used the higher the hardness
on the resulting compound Conveyor Belt was also higher, and if the amount of
carbon was very low then the resulting hadrness was very low which was not in
accordance with the standards used hadrness so do not meet the standard of quality in
the products produced Conveyor Belt.
Based on the research that has been done on hardness conveyor belt at PT. IKN was
the large amount of carbon black was used in order to meet the standart hardness was
7 kg conveyor belt with a hardness of 65 Shore A. | en_US |
