Penentuan Waktu Kemantapan Mekanis (MST) Lateks terhadap Tegangan Tarik (Green Modulus) 300% Benang Karet Pt. Industri Karet Nusantara

Abstract

Concentrated latex is one of the production of rubber plantations which greatly affects the quality of the resulting rubber thread. One of the parameters used concentrated latex test is the test of mechanical stability time. This value greatly affects the mechanical stability of a physical nature that is 300% tensile stress associated with the quality of the resulting rubber thread. If the value of a high mechanical stability of the 300% tensile stress is low, the resulting rubber thread produced is very fragile and easily broken. Conversely, if the value of low mechanical stability of the tensile stress was 300% higher resulting in yarns produced rubber becomes hard and rigid. The relationship between the mechanical stability of the 300% tensile stress is inversely linear. Thus, to produce 300% tensile stress is good for rubber thread, then the mechanical stability of the time value used is 500-2000 second
