| dc.description.abstract | Natural rubber is an polymer from isoprene by the name of chemistry of Cis – 1,4
polisoprena. One of product from this rubber is Rubber Thread. Raw material originally
used is latex. TSC ( Total Solid Content ) determination of latex is to be done to obtain
the quality parameters which adjust to produce a good quality for produced products.
The one of the parameters is stensile strength. If the TSC too high, then the tensile
strength of rubbet Thread Produced larger, so that Rubber thread will be stiff. While if
when low TSC, tensile strength also will lower, so rubber thread produced will easy to
tear and loosen of if when pulled.
To determine the TSC of latex which used for rubber thread with heated. It was done with
volumetric method when heating during 3 hours. To get the TSC concentrated from
analysis result. Everyday during 4 times taking over and doing 3 times. The based of
quality rubber thread factory standart, that’s why TSC of latex concentrated at medium
ammoniac is 61,3% - 62%. In this case, TSC concentrated at rubber thread factory to
match with standart. | en_US |
