Pengaruh Konsentrasi Asam Asetat (CH3COOH) terhadap Modulus Green 300% pada Proses Produksi Benang Karet di PT. Industri Karet Nusantara

Abstract

Concentration acetic acid (CH3COOH) influences one of rubber thread physical parameter namely green modulus 300%. If acetic acid index of rubber thread is high so green modulus 300% is high also which is produced become less elastic and too hard. And if the concentration acetic acid is low so green modulus 300% is low too, which effects rubber thread which is produced become slack and easy broken.

The contact between concentration acetic acid and green modulus 300% is linier which comparison is diametrical. Concentration acetic acid which appropriate to rubber thread so that is obtained green modulus 300% which requires standard is 28 – 32%.
