摘要
[Object] To provide a method for detecting water in plastics and a water removal system for plastic materials that enable an amount of water contained in a plastic to be measured accurately and rapidly. [Solution Means] A plastic 13 of known moisture state is irradiated with electromagnetic waves of a bandwidth of 50 GHz to 1000 GHz from an oscillating apparatus 11 and the remaining electromagnetic waves not absorbed by the plastic 13 are received and measured by a receiver 12 to acquire a first measurement value in advance. The plastic 13 of unknown moisture state is then irradiated with the electromagnetic waves of the bandwidth of 50 GHz to 1000 GHz from the oscillating apparatus and the remaining electromagnetic waves not absorbed by the plastic 13 are received and measured by the receiver 12 to acquire a second measurement value. The first measurement value and the second measurement value are compared to compute the moisture state of the plastic of unknown moisture state.
