Embodiment Construction

[0022] The aging box suitable for tubular samples according to the present invention will be further described in detail below in conjunction with the accompanying drawings. An aging box suitable for tubular samples, the aging box suitable for tubular samples includes a sample holder 2 for fixing a tubular sample 3 and a strip-shaped aging light source 8, the length direction of the aging light source 8 is in line with the The axis of the tubular sample 3 that the aging box can handle is parallel, and the sample holder 2 can drive the tubular sample 3 handled by the aging box to rotate with the axis of the tubular sample 3 as the axis, between the sample holder 2 and the aging light source 8 are provided with two light-shielding baffles 7, and an elongated gap is formed between the two light-shielding baffles 7. The length direction of the gap is parallel to the length direction of the aging light source 8, and the rays emitted by the aging light source 8 can only pass through ...

Abstract

The invention provides an aging box suitable for tubular samples, comprising a sample holder (2) for fixing the tubular sample (3) and a strip-shaped aging light source (8), the length of the aging light source (8) The direction is parallel to the axis of the tubular sample (3) that the aging box can handle, and the sample holder (2) can drive the tubular sample (3) handled by the aging box to take the axis of the tubular sample (3) as the axis Turn, two shading baffles (7) are arranged between the sample holder (2) and the aging light source (8), and a long strip-shaped gap is formed between the two shading baffles (7), and the aging light source (8) The emitted rays can only be irradiated on the surface of the tubular sample (3) processed by the aging box through the gap. The aging box can carry out the accelerated aging test of the external surface laboratory light source for the pressure pipe / gas cylinder made of polymer materials, and can provide qualified tubular polymer samples with uniform aging degree on the external surface for further tests.

Description

technical field [0001] The invention relates to the technical field of polymer material testing, in particular to an aging box suitable for tubular samples. Background technique [0002] In recent years, with the rapid development of the polymer material industry and the maturity of technology, non-metallic pressure-bearing equipment adopts full polymer, polymer composite materials or polymer coating materials for surface modification, mechanical bearing, engineering anticorrosion, etc. There are more and more cases of even completely replacing metal materials, and they play an important role in important fields such as people's livelihood construction and economic development in our country. However, due to the particularity of the service environment of pressure equipment, many of its components are often induced by multiple aging factors such as natural environment and industrial environment. For special equipment, the main hazard of polymer material aging is the loss of...
