Aging tank suitable for tubular samples
2014
The present invention provides a suitable sample tube aging tank, comprising means for fixing a tubular sample (3) a specimen holder (2) and aging elongated light source (8), aging light source (8) of the length the tubular sample (3) in the direction of the aging tank can handle parallel to the axis, specimen holder (2) capable of driving the processed tubular aged sample tank (3) to the tubular sample (3) the axis of the shaft rotated, between the specimen holder (2) and aged source (8) is provided with two light shielding shutter (7), forming a nip between two elongated light shielding shutter (7), aging of the light source (8) rays can be emitted only in the surface of the sample tube (3) the aging tank processed by irradiating the nip. The aging tank can be uniformly outer surface of the degree of deterioration of the tubular outer surface of the polymer sample source laboratory accelerated aging test, and the test can be provided for further qualified for pressure pipe made of the polymer material / gas cylinders.
