Product details
Light aging test chamberProduct Introduction
The UV box can reproduce the hazards that occur outdoors for months or years in a matter of days or weeks. The types of hazards include fading, discoloration, loss of gloss, powdering, cracking, turbidity, bubbles, brittleness, strength, deterioration, and oxidation. This test chamber is suitable for evaluating the UV resistance performance of materials such as storage polymer materials, protective layers, photovoltaic modules, etc
Box structure: Box shell material: SUS stainless steel plate spray treated; Inner liner material: SUS stainless steel plate;
Box cover material: SUS stainless steel plate with spray coating treatment;
Install a total of 8 UV-A or UV-B ultraviolet lamps on both sides of the studio;
The heating method is the inner pot sink type heating, which heats up quickly and has a uniform temperature distribution;
The box cover is a double-sided flip cover, which can be opened and closed easily and freely;
The inner tank water level automatically replenishes to prevent the heating tube from burning out and being damaged;
The sample holder is made of stainless steel or aluminum alloy;
The bottom of the test chamber adopts high-quality fixed PU movable wheels;
The drainage system uses vortex and U-shaped sedimentation devices for drainage;
The surface of the sample is parallel to the plane of the ultraviolet lamp;
The spray type equipment is equipped with automatic nozzles inside, and the water pressure can be adjusted;
If the lamp is on, once the door of the box is opened, the machine will automatically cut off the power supply to the lamp and enter a balanced state for cooling to prevent harm to the human body;
Over temperature protection inside the box. When the temperature inside the box is too high, the machine will automatically cut off the power and enter a balanced state for cooling
Light aging test chamberThe control system:
The temperature and humidity control instrument adopts a fully imported high-precision digital display microcomputer integrated controller from South Korea; Accuracy: 0.1 ℃ (display range); Resolution: ± 0.1 ℃; Temperature sensor: PT100 platinum resistance thermometer;
