Pengaruh Konsentrasi Asam Asetat (CH3COOH) terhadap Tegangan Tarik (Green Modulus 300%) Benang Karet (Count 37 Sw Ends 40) PT. Industri Karet Nusantara

Abstract

Acetic acid is the important agent in compound coagulating of rubber thread process. The concentration of acetic acid influence on of rubber thread physical properties that is green modulus 300%. The quality of rubber thread’s green modulus 300% was determined by compound coagulating phase that used acetic acid. If the using of acetic acid high so green modulus 300% will be high too, it cause rubber thread become hard and rigid. And if the using of acetic acid low, green modulus 300% will be low and it makes rubber thread will be brittle and easy break. So, to get a good rubber thread’s green modulus 300% the using of acetic acid is according with the standard that is 28- 32 %.
