Tower Type UV Aging Testing Chamber DH-RUV-1

Standard:

ASTM G 153, ASTM G 154, ASTM D 4329, ASTM D 4799, ASTM D 4587, SAE J2020, ISO 4892 All current UV weathering test standards.

Function:

This UV accelerated aging test chamber uses imported UVA-340 fluorescent UV lamps as light sources, which can simulate the damage caused by sunlight, rain and dew. The UV weathering chamber uses fluorescent UV lamps to simulate the effect of sunlight and uses condensed moisture to simulate dew. The tested material is placed in a cycle of alternating light and moisture at a certain temperature for testing, and the material is subjected to accelerated weathering tests to obtain the results of the material's weathering resistance. The UV chamber can reproduce the damage that occurs outdoors for months or years in a few days or weeks. The types of damage include: fading, discoloration, loss of gloss, pink light, cracking, turbidity, bubbles, brittleness, strength, decay and oxidation. This machine contains a spray device.

This UV accelerated aging test chamber can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, darkness, etc. in natural climates, and by reproducing these conditions, merge them into a cycle and let it automatically execute the number of cycles. This is the working principle of the UV aging test chamber. During this process, the equipment can automatically monitor the blackboard temperature and water tank temperature; 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 the specified set value, and greatly extend the service life of the lamp.

Specification:

Light Source:

The light source uses 8 imported ultraviolet fluorescent lamps with a rated power of 40W as the light source. The ultraviolet fluorescent lamps are distributed on both sides of the machine, 4 on each side. There are UVA-340 and UVB-313 light sources for users to choose and configure. The luminous spectrum energy of the UVA-340 lamp is mainly concentrated at a wavelength of 340nm, and the luminous spectrum of the UVB-313 lamp is mainly concentrated near a wavelength of 313nm. We use UVA-340 lamps. Since the energy output of fluorescent light will gradually decay over time, in order to reduce the impact of the test caused by the decay of light energy, this test box replaces an old lamp with a new lamp every 1/4 of the fluorescent lamp life. In this way, the ultraviolet light source is always composed of new and old lamps, so as to obtain a constant output of light energy. The effective service life of the lamp can be about 1600 hours.

Electrical Control:

a. Blackboard temperature and condensation temperature are both controlled by controllers.

b. The rest are basically imported electronic components.

Irradiance uniformity: ≤4% (at the sample surface)

Blackboard temperature monitoring: standard Pt-100 blackboard temperature sensor is used to accurately control the sample surface temperature during the test process.

Blackboard temperature setting range: BPT 40-75℃;

But the actual maximum temperature limit of the temperature protection device inside the machine is 93℃±10%.

Blackboard temperature control accuracy: ±0.5℃,

c. Water tank temperature monitoring: During the cycle test, there is a test section that is a dark condensation process, which requires the box to produce high-temperature saturated water vapor. When the water vapor encounters the relatively cold sample surface, it will condense on the sample surface.

The water tank is located at the bottom of the box and has a built-in electric heater.

Water tank temperature control range: 40~60℃

d. The test chamber is equipped with a time controller with a range of 0~530H and a power failure memory function.

e. Safety protection device:

◆ Over-temperature protection inside the box: When the temperature inside the box exceeds 93℃±10%, the machine will automatically cut off the power supply to the lamp and heater and enter the equilibrium state to cool down.

◆ Low water level alarm in the water tank to prevent the heater from burning out.

Standard Sample Clip:

◆ Several 75×150mm

or 75×290 mm standard sample clamps are randomly provided.

The maximum thickness of the sample can reach 20mm.

Users need to specify non-standard sizes when ordering.

When sample rack and sample clamps are not needed, they can be loaded directly.

◆14 rows/side of standard sample clamps, one row on the back is used to place a blackboard thermometer.

◆Easy to open the machine door.

Chamber Material:

◆ The inner shell of the box is made of SUS304# stainless steel plate

◆ The outer shell is made of high-quality cold-rolled steel plate sprayed with plastic

◆ The sample rack is made of stainless steel and aluminum alloy mesh frame, which is convenient for sample storage and retrieval

Machine Overview:

◆ Dimensions: Approx. H1370mm×W1350mm×D 530 mm

◆ Weight: Approx. 150 kg

KUV3 Host Requires Working Environment Conditions:

◆ Power supply requirements: 220V±5%, single-phase three-wire, 50Hz, 8A, 10A slow-blow fuse required.

◆ Environment: 5~35℃, 0~80%RH, good ventilation, clean indoor environment.

◆ Work area: about 234×353cm

◆ Drainage: There needs to be a drainage ditch on the floor near the host.

◆ For easy movement, casters are installed at the bottom of the instrument, and the position is fixed.then use a U-shaped ring to fix the position of the test machine.

Controller:

The equipment uses a true color touch screen PID temperature intelligent controller with high temperature control accuracy and good stability.

Installation Location:
