Why use xenon lamp weather test chamber for aging test of auto parts

Xenon lamp weather resistance tester is this kind of comprehensive weather test equipment. In addition to the weather aging test, it can also carry out the light resistance test of the fiber material, that is, the fiber material is exposed to the sunlight spectrometer that simulates the penetration of laminated glass. The synthetic light source comes out to comment on the color fastness characteristics of raw materials. Carry out simulation and enhanced experiments from several key climate elements such as light energy, temperature, precipitation or essence, and environmental humidity; choose a xenon arc lamp that can simulate a full solar spectrometer to reproduce what exists in a different natural environment Destructive nano. The xenon lamp weather-resistant environmental test box can show relative environmental simulations and speed up experiments for scientific research, product development and quality management, and can be used for experiments such as the selection of new materials, the improvement of current raw materials or the evaluation of the durability of raw materials after the transformation; Suitable for plastics, vulcanized rubber, paints, architectural coatings, printing inks, paper types, medicines, foods, skin care products, textile products, auto parts, packaging products, building decoration materials, electric welder products, etc.

Is it necessary to use a xenon lamp weather-resistant environmental test box for accelerated aging testing of auto parts? Now I will explain to everyone one by one.

1. In order to reduce the instability of testing and ensure the degree of testing, maintenance and calibration of machinery and equipment should be carried out according to the guidance of the machinery and equipment manufacturers.

2. The water used for self-spraying, dampness, or other main purposes shall not leave all alluvial deposits or stains on the test sample. The water content of liquid particles in common water should not exceed 1ppm, and the water content of sio2 should not exceed 0.2ppm. The measurement of water content of sio2 should refer to ASTM D 859 or ASTM D 4517. The composition is solved by de-ionization method and reverse osmosis method to obtain water with specified purity.

3. When testing the interior of the car, if it will, turn off all the sprinklers on the machinery and equipment to avoid accidental self-spraying on the test product.

4. When inspecting car interiors, according to the installation of suitable filters, the spectrometer output power of the xenon arc lamp (SPD) conforms to Table D2 or D3 in Annex D.

5. When inspecting automobile exterior parts, according to the installation of suitable filters, the spectrometer output power distribution (SPD) of the xenon arc lamp shall meet the requirements. For the typical spectrometer coverage, please refer to Table D1 or D3 in Annex D.

For the inspection of car interiors, a certain type of circulatory system in Table 1 can be selected for inspection based on the situation. Standard parameter value of automobile interior decoration experiment

For the detection of automotive exterior parts, a certain type of circulatory system in Table 2 can be selected for testing according to the situation.
