| Summary: | Most of Indonesian rubber products SIR 20 are made from the material of raw rubber obtained from
smallholders. However, the quality of this material is not good enough. Thus, quality improvement has to be carried
out by manufacturers. The liquid smoke used during the blanket hanging process can improve the quality of the
rubber products SIR 20. This research aimed to determine and study the effects of liquid smoke spraying and blanket
hanging duration on the drying factor, the dry rubber content, technical quality, vulcanization characteristics, and
physical properties of vulcanized natural rubber. Treatments consisted of various hanging duration (6, 8, and 10
days, and without hanging) and spraying (with and without spraying of liquid smoke). The results showed that
the spraying of liquid smoke on natural rubber blankets could improve the technical quality of the natural rubber,
especially the values of Po and PRI. The spraying of liquid smoke could reduce the blanket hanging duration to 6-8
days. The blankets sprayed with liquid smoke had the optimum cure time of around 15 minutes and 19 seconds and
the scorch time of around 3 minutes and 22 seconds. These values indicated that the vulcanization characteristics of
blankets which were sprayed with liquid smoke were generally better than those of blankets which were not sprayed
with liquid smoke |
