Do you often encounter the situation of leather cracking, peeling and degradation of fracture performance? Have you ever seen the paint turn white or fade? The important reason for the above reasons is that sunlight causes material degradation and aging, which is closely related to sunlight and humidity. Different materials have different responses to the spectrum. Generally speaking, short wave ultraviolet radiation is an important factor leading to the aging of durable materials; Long wave ultraviolet and even short wave visible light are the main reasons for degradation of non durable materials.
Is there any way to quickly simulate the test? Haida specially developed a xenon lamp weathering test chamber to simulate the hazards caused by sunlight, rain and dew. The principle is that xenon lamp is used to simulate the effect of sunlight, condensed moisture is used to simulate rain and dew, and the tested materials are placed in the cycle program of alternating light and moisture at a certain temperature for testing, so that the hazards that occur outdoors for months or even years can be reproduced in a few days or weeks. The data of artificial accelerated aging test can help to select new materials, modify existing materials, and evaluate how changes in formula affect the durability of products. Suitable for automotive interior and exterior materials, electronic product shells, plastics, textiles, coatings and other materials. Product reference standards:
GB/T 16422. 2-2014
SAE J2412- 2004
What are the working characteristics of this instrument?
a). Ventilation and cooling device: the temperature ventilation and cooling system of the test chamber is automatically controlled by the temperature controller, and the cooling system is adopted in the chamber.
b) The control blackboard thermometer adopts wired transmission technology, which effectively improves the control accuracy. The sample holder is equipped with a blackboard thermometer BPT or a black standard thermometer BST
c) Optical fiber transmission is used to measure the radiation intensity of xenon lamp, so as to avoid the problem of measurement error caused by temperature.
d) Device: In order to record the working time of each test, the equipment is equipped with a timer on the operation panel, which can control the equipment time, and the equipment will automatically shut down when the timing is over.
e) Protective device: In order to ensure that the xenon arc lamp can work normally without damage, the xenon lamp will automatically extinguish when the door is opened, and the whole machine will stop working.
f) Temperature range RT+10 ℃～ 70 ℃; Humidity range: 20~60% RH; Dark 30%~98% RH
The temperature on the blackboard is 60 ℃～ 100 ℃, and the darkness is 40 ℃～ 70 ℃; Temperature deviation ± 3 ℃
