The main function
This ultraviolet accelerated aging test box adopts imported UVA-340 fluorescent ultraviolet lamp as the light source, which can simulate the harm caused by sunlight, rain and dew. The UV weatherproof box uses fluorescent ultraviolet lamps to simulate the effect of sunlight, and uses condensed moisture to simulate dew. The tested material is placed in a cycle program of alternating light and moisture at a certain temperature for testing, and accelerated weather resistance test is performed on the material to obtain the weather resistance result of the material. The UV box can reproduce the hazards that occurred outdoors for months or years in a few days or weeks. The hazard types include: fading, discoloration, loss of gloss, pink, cracking, turbidity, bubbles, embrittlement, strength, decay, and oxidation. This machine contains spray device.
This ultraviolet accelerated aging test box can simulate the environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, darkness, etc. in the natural climate, by reproducing these conditions, merge into a loop, and let it automatically execute the loop to complete the loop frequency. This is the working principle of the UV aging test chamber. In this process, the equipment can automatically monitor the temperature of the blackboard and the water tank; by configuring the irradiance measurement and control device (optional), the light irradiance can be measured and controlled to stabilize the irradiance at 0.76W/m2/340nm or Specify the set value, and greatly extend the life of the lamp.
In line with international standards
ASTM G 153, ASTM G 154, ASTM D 4329, ASTM D 4799, ASTM D 4587, SAE, J2020, ISO 4892 All current UV aging test standards.
The box-type UV accelerated testing machine of Hongjin Instrument is self-produced and self-sold, eliminating intermediate links, maximizing customer benefits, and the quality of the equipment does not shrink, spending less money to buy the box-type UV accelerated testing machine you want .
