JSX-UVA-263 UV lamp aging test chamber

  • Profile.

The UV Accelerated weathering test chamber (UV aging test chamber) stimulates dew and rain with consideration for humidity and/or water spray equipped with a fluorescent UV lamp which can completely simulate the UV spectra of sunlight, and exposes materials to alternating cycles of UV light and moisture at controlled. It’s most widely used for weathering test for types of damages include color change, gloss loss, chalking, cracking, crazing, hazing, blistering, strength loss and oxidation. It adopts 8 pieces of UV lamps (40W) as the light source. The lamps are distributed on the two sides inside the chamber, 4 pieces for each side (UVA-340 or UVB-313 optional).

  • Structure introduction
  • Machine material: 304# high-level stainless steel
  • The air duct inside the chamber adopts single circulation system with an imported axial flow fan, which improves the flowing speed and heating ability, and greatly improves the temperature uniformity.
  • Water source and consumption: Tap water or distilled water about 8liters per day.
  • Water tank liner heating which makes heating up fast and uniform temperature distribution
  • Automatic water-supplying of liner prevents heating pipe from damage due to air burning;
  • The lid is a two-way clamshell which makes open and close easily.
  • Sample holder material: SUS304 or aluminum alloy steel
  • High quality PU active wheel to fix the machine
  • U-shape sedimentation drainage is used to drain water
  • The surface of sample is parallel to the plane of UV lamp
  • Drainage system uses U-type sedimentation device drainage
  • Sprinkler system with built-in automatic sprayer and with water pressure adjustable
  • Safety protection device
  • ground protection
  • power source overload and short circuit breaker
  • control loop overload and short circuit fuse protector
  • water shortage protection
  • thermal protection
  • Temperature control
  • UV: The first-order optical reaction is not sensitive to temperature changes, however, the subsequent secondary reaction velocity is closely related to the temperature change. In general, reaction rate will accelerate with temperature rise, therefore, in the process of UV exposure test, temperature control is very important, what’s more important is to make test temperature used in acceleration test be well-matched with the highest temperature encountered of material in the practical application. Temperature in the process of UV test is set between 50 ° C and 70 ° C, depending on the light level and RM temperature. Temperature regulation of the equipment is accomplished by a series of systems such as air heaters, water heaters, etc., which are controlled by a controller with a microcomputer calculation function.
  • Humidity: As temperature increases, the damaging effect from moisture on the material also increases dramatically. Therefore, in the process of humidity test, temperature control is the most basic requirement. Further, to maintain a high temperature environment is required for the acceleration effect during the test.
  • Heating system
  • U-shape high-speed titanium heating tube
  • Independent temperature control system and lighting system;
  • Temperature control output power is calculated by the microcomputer, in order to achieve high precision and high efficiency;
  • Thermal protection function available for heating system.
  • Blackboard temperature is controlled to be heated by using color touch screen programmable controller or digital keypad temperature controller; output power is calculated by microcomputer, PID self-tuning; monitoring adopts standard PT100 blackboard temperature sensor.
  • The temperature of sink is controlled by a Korean temperature controller. The sink is located in the lower part of the cabinet with electric water heater built in. During the test, one of the test sections is a dark condensation process, which requires the production of saturated water vapor at higher temperatures inside the chamber. When the steam encounters a relatively cold sample surface where dew is condensed.
  • Light source system

Types of light source (simulate the UV light in sunlight)

Light source: 8 UV fluorescent lamps with rated power of 40W, UVA-340 and UVB-313 light source for users to choose. Like other lamps, the aging of the QUV tube causes the lamp output to drop, and the QUV without the Irradiance meter control system uses the rotational position method to compensate. This system can be used for many application standards, but it has inherent limitations. This method of changing position does not compensate for the effects of different batches of lamps or the surrounding environment.

  • UVA-340: A wavelength that emits sunlight from 365 nm to 295 nm, and its radiation peak is at 340 nm. UVA-340 is especially useful for control tests in different tests, with the best simulation of sunlight in the short-wave UV range.Accelerated Uv Lamp Aging 40W Environmental Test Chamber 3

 

b) UVB-313: The wavelength range is between 280 nm and 315 nm. UVB-313 ages faster than UVA-340 lamps, but their shorter wavelengths than the sun cutoff point can have unrealistic results for many materials.
