Provided is a liquid crystalline polyester fiber capable of achieving improved weatherability without kneading a UV absorber into the fiber or attaching a weatherable UV absorber after fiber spinning. The liquid crystalline polyester is a fiber that consists essentially only of a liquid crystalline polyester, in which the amount of UV absorber used is 5 mass % or less, and the strength retention in the weather fastness test with xenon arc lamp light in accordance with JIS L 0891 is 60% or more.

The application discloses a kind of weathering aging performance detection devices for modified silica gel new material children tableware detection, it is related to new material detection technical field, including aging cabinet, the xenon arc lamp is installed in the aging cabinet, soaking groove is arranged in the aging cabinet.The weathering aging performance detection devices for modified silica gel new material children tableware detection, by driving mechanism drives silica gel chopsticks reciprocating motion, realize the intermittent contact and separation of tableware and olive oil medium, restore the real state of tableware alternate contact grease, exposed in air in daily use;While cooperating with mechanical fatigue loading mechanism, simulate the bending deformation and friction loss in the process of tableware use, realize the coupling detection of environmental aging and mechanical fatigue aging, completely solve the drawbacks of traditional equipment single aging detection, let detection working condition highly fit actual use scene, greatly improve the authenticity and reference value of detection data.

The invention provides a photo-thermal power generation solar energy absorption coating service performance test device and method, and relates to the technical field of photo-thermal power generation. The method solves the problem that the technical blank of the comprehensive evaluation method for the service characteristics of the coating under the synergistic effect of factors such as cold and hot alternation, sun illumination and sand wind is obvious for the service characteristic evaluation method for the tower-type photo-thermal power generation solar energy absorbing coating. The device comprises a test box, a water tank, an air blower and a control box, the water tank, the air blower and the control box are all connected with the test box, a xenon arc lamp is installed at the top end in the test box, a multi-layer test rack is arranged in the middle of the test box, a heating module is arranged at the bottom of the test box, a spraying pipe is arranged between the xenon arc lamp and the test rack, and the test rack is obliquely arranged relative to the bottom face of the test box. A sand containing tray is placed on the heating module, and an air blowing opening is formed in the side wall of the bottom of the test box. The method is mainly used for evaluating the service characteristics of the solar absorbing coating.
