Pengaruh Radiasi Neutron Terhadap Waktu Relaksasi Spin-Kisi (T1) Pada Polimer Polivinil Klorida (Pvc) dengan Spektroskopi Nmr Pulsa

TL;DRAbstract

A research measurement of spin-lattice relaxation time (T1) with a pulse NMR spectrometer as well as a test of strength (tensile test and compression test) polymer material PVC (Poly Vinyl Chloride) with tools united-1 test system SFM SFM-30. The study aims to investigate the influence of the neutron fluence on the spin-lattice relaxation time (T1) and to determine the PVC polymer material strength test. On the measurement of the spin-lattice relaxation time (T1) is used method pulse 180o-t-90o and pulse method 90o-t-90o, by means of NMR minispec P.20. Measurement of PVC polymer material strength testing using tools united-1 test system SFM SFM-30. The results showed that the spin-lattice relaxation time (T1) PVC polymer influenced by variations in relaxation times (fluence) neutrons. From the graph of the spin-lattice relaxation time (T1) vs. neutron fluence with the method 90o-t-90o obtained increases and decreases in the value of T1. The value of the spin-lattice relaxation time at
