The ultraviolet weather resistance test chamber is a very common experimental instrument, which provides great convenience and promotion to many industries and production enterprises. However, due to the complexity of the manufacturers of ultraviolet light weather resistance test chambers in the modern market and the uneven quality, how to effectively buy a device with excellent quality and performance? Mainly pay attention to the following aspects: <1> Product use The ultraviolet weather resistance test chamber simulates the ultraviolet radiation and condensation in the sunlight of nature, and accelerates the weather resistance test of the material to obtain the result of the weather resistance of the material. By reproducing environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, darkness, etc., they are combined into one cycle, and it is automatically executed to complete the number of cycles. Whether the purchased equipment can be used will not play a role. This is the first factor that customers should consider. <2> Light source selection of test chamber At present, the main technical core point of the xenon lamp aging test box and ultraviolet light weathering test box in the domestic market is the light source system. However, the domestic xenon lamp manufacturer does not have the authenticity of the test light source, and the spectral divergence is very obvious. The xenon lamp aging test box made with domestic lamps is not technically reliable. What's more, domestic unscrupulous manufacturers use sterilized ultraviolet lamp devices in the ultraviolet aging test box, and they simply cannot achieve the aging and destruction effects they should have. However, due to the high price of foreign equipment, general small and medium-sized enterprises do not have the ability to accept and generally do not have the judgment in product selection. Beijing Yashilin adopts 8 imported ultraviolet fluorescent lamps with a rated power of 40W as the light source. Ultraviolet fluorescent lamps are distributed on both sides of the machine, with four on each side. There are UVA-340 and UVB-313 light sources for users to choose and configure. These UV lamps mainly produce ultraviolet light instead of visible light and infrared light. The main difference between lamps is the total UV energy they produce in their respective wavelength ranges. Different lamps will produce different test results. The actual exposure application environment can prompt which type of UV lamp should be used. This factor plays a large role in guiding customers' purchase. <3> Technical indicators of equipment Beijing Yashilin ultraviolet weather resistance test box for your reference: 1. Temperature range: RT + 10 ℃ ～ 70 ℃ 2. Humidity range: ≥98% RH 3. Temperature fluctuation: ± 0.5 ℃ 4. Temperature control method: PID self-tuning temperature control method 5. Distance of lamp center: 70㎜ 6. Distance between sample and lamp center: 50㎜ 7. Standard specimen size: 75 × 300㎜ 8. Irradiance range: ≤10W / m2 9. Ultraviolet light and condensation time are alternately adjustable 10. Ultraviolet wavelength: UV-A wavelength range is 315-400nm 11. Test time: 0 ～ 9999H adjustable <4> Material of equipment Most of the test boxes are basically made of steel plate in appearance. However, there are many types of steel plates, and there are differences in quality. The shell and cover of the Beijing Yashilin ultraviolet weather resistance test box are made of A3 spray-treated steel plate, and the inner tank is made of SUS stainless steel plate. <5> Circuit system and safety protection Whether the circuit system of the equipment is standardized and orderly, and whether it is safe or not, is also one of the key points for customers to consider. This is related to the performance of the equipment and the safety of the surrounding environment. Share the environment, share the Yashilin equipment! The above article is for reference only, customers can choose according to their specific requirements.
