Penentuan Regangan Tarik (Green Modulus) 300% Benang Karet terhadap Pengaruh Waktu Kemantapan Mekanis (MST) Lateks PT. Perkebunan Nusantara III.

Abstract

Concentrated latex is one kind of rubber plantation production which greatly affects the quality of the rubber thread produced. One of concentrated latex test parameters used are the mechanical stability of test time. This value greatly affects the mechanical stability of one of the physical properties are 300% tensile strain associated with quality value which is derived karte thread. If the value of the high mechanical stability, the 300% tensile strain is low resulting in a rubber thread that produced very fragile and easily broken. Conversely, if the value of stability meknisnya lower then 300% tensile strain is high which resulted thread that produced rubber becomes hard and rigid. The relationship between the value of the mechanical stability with 300% tensile strain is inversely proportional. So, to produce a 300% tensile strain well to rubber thread. Then the time value of mechanical stability in use is 500 - 2000 second.
