Pengaruh Swelling Indeks Compound terhadap Tegangan Tarik (Green Modulus 300%) pada Proses Benang Karet Count 37 NS 40 PT Industri Karet Nusantara Medan

Abstract

Concentrated latex is on important product quality of plantation langely effects the quality of number thread produced. One of parameters physical of gainning best quality of concentrate latex is green modulus 300%. If swelling index of rubber thread is high so green modulus 300% is low which effects rubber thread which produced become likely to snap. One the other hand, if swelling index is low so green modulus 300% is high which effects rubber thread which is produced become easy slack. The relationship between swelling index and green modulus 300% is linear which inversely proportional. Swelling index which appropriate to rubber thread count 37 NS 40, so that is obtained green modulus 300% which reguires standard of factory is 1,93 – 2,01.
