1、 Product Overview

Xenon lamp weather resistance test chamberIt is a test equipment that uses xenon lamps as light sources to simulate and enhance weather resistance and accelerate photo aging, in order to quickly obtain near atmospheric aging test results and evaluate the weather resistance of materials. Weather resistance test is an important means of screening and optimizing product composition in the scientific research and production process, and it is also an important content of product quality inspection. Materials such as coatings, plastics, aluminum-plastic panels, and automotive safety glass are required to undergo weather resistance tests according to product standards.

The main factors causing material aging are sunlight and humidity. The weather resistance test chamber can simulate the hazards caused by sunlight, rainwater, and dew. The weather resistance test chamber uses xenon lamps to simulate the effect of sunlight exposure, and uses condensed moisture to simulate rainwater and dew. The tested material is placed in a cyclic program of alternating light and moisture at a certain temperature for testing. It takes several days or weeks to reproduce the hazards that occur outdoors for months or even years. Artificial accelerated aging test data can help select new materials, modify existing materials, and evaluate how changes in formulations affect product durability.

Water shortage protection.

• High speed circuit protector (protecting heating)
• Electric motor (blower/freezer) overload thermal relay (protects blower/freezer from overload)
• High pressure switch for freezer (protects compressor, extends service life)

Circuit breaker for protecting electric motors (refrigerators) (protecting compressors, extending service life)

four 、 Installation environment

1． The product should be installed in a relatively clean environment,There is less dust in the air,In an environment without corrosive and harmful gases.

2． The product has no special requirements for the temperature and humidity of the environment,But it should also be avoided to install at temperatures that are too high or too low,And in very humid or particularly dry environments. Ambient temperature10～35℃

3． Xenon arc lamps and filters are fragile items, so they should be installed firmly when leaving the factory,Special care should be taken during installation to avoid unnecessary losses.

5、 Maintenance and Precautions!

1. Operating equipment must avoid moving parts such as equipment rotation to prevent personal injury.
2. Xenon lamps that are ignited must not be observed directly or by other methods without isolation.
3. During use, it is advisable to avoid frequent ignition of xenon lamps as much as possible,To delay the service life of xenon lamps,After the xenon lamp is turned off, the reignition time should not be less than10minute.
4. The water used during the experiment must be clean distilled water,To prevent other impurities from contaminating the components and samples of the instrument.
5. Regularly check whether the waterway system is unobstructed,If there is a blockage in the nozzle, it can be cleared with a metal wire and cleaned. Listen carefully.
6. The luminous efficiency of xenon lamps will decrease after a certain period of use,The lamp tube should be replaced with a new one.
7. After the experiment is completed, the power circuit breaker should be pulled down,Turn off the xenon lamp cooling water.
8. If electrical components malfunction and need to be repaired or replaced, please replace them with the same model of components.
9. The equipment should be operated and maintained by dedicated personnel.
10. After long-term testing,Clean the water storage tank.
11. When starting the sample rack speed controller,Be sure to turn on the power switch before turning on the speed control knob,The stop time should be set to zero by turning the speed control knob first,Turn off the power switch again.
