SANWOOD Xenon Lamp Weathering Chamber

SANWOOD Xenon Lamp Weathering Chamber


Sanwood Xenon Lamp Weathering Chamber is exported to Russia, Europe, USA, Canada and so on.

In many outdoor environments, materials are often eroded by rain or other moisture. B-SUN's water spray can be better simulate the final environmental conditions.
Water spray is very effective in simulating thermal shock or mechanical erosion due to temperature drastic changes and rain wash.In some practical application conditions, such as sunlight, when the accumulated heat rapidly dissipates due to sudden showers, the temperature of the material changes sharply, producing thermal shock, which is a kind of test for many materials. test.

B-SUN's water spray can simulate thermal shock and/or stress corrosion.
The B-SUN sprinkler system is designed with 2 nozzles, one piece on each side of the top of the test box; The sprinkler system can be operated for a few minutes and then closed.

Test Principle

Artificial weathering of coatings or exposure of coatings to filtered xenon-arc radiation is carried out in order to obtain the degree of change in as elected property after a certain radiant exposure H, and/or the radiant exposure which is required to produce a certain degree of ageing. The properties selected for monitoring should preferably be those which are important for the practical use of the coatings. The properties of the coatings exposed are compared which those of unexposed coating prepared from the same coating materials at the same time and in the same way (control specimens)or with those of coatings exposed at the same time whose behavior during testingin exposure apparatus is already known (reference specimens).

 Xenon Lamp light can emulate the effect of sunshine,while water spray system can emulate the effects of rain and dew. During the test, radiation energy and temperature are controllable. A typical test cycle generally carries out under strong irradiation of Xenon light and periodic precipitation. These tests generally appliedin the fields of paint and coatings,automotive industry, plastic, wood, glue,etc…

SANWOOD Xenon lamp aging test chamberhere in after referred as B-SUNuse Xenon lamps as artificial light source, and canmodify the full spectrum sun light. Controlling the temperature, humidity .It sinner temperature and humidity can be properly controlled to obtain the periodic precipitation on the sample for fully evaluating the damaged factor caused by sunlight, moisture and temperature (materials aging phenomenon includes fading, disluster, intensity reduction, racking, flaking, chalking, and oxidation). 


■ Xenon test chamber have Three xenon lamps imported from America can offer higer irradiance energy, meet with all test strandards’ requirements.
■ Can set and control automatically the relative humidity of working room.
■ The test procedures can be programmed freely; and up to 16 predetermined procedures can be saved in one time. Every procedure includes up to 10 segments setting data.
■ Can set the cumulative energy (total irradiance energy)obtained by sample to finish a test procedure.  
■ With spray function, can set spray time and spray interval time.
■ Irradiance energy can be accurately controlled. The "Sun Eye" control system can automatically compensate the change of light intensity caused by ageing or other factors.
■ Users can easily calibrate and adjust the irradiance or the blackboard temperature by themselves.
■ With High precision Pt100 Temperature sensor. Blackboard temperature is auto-controlled during the whole process
■ Over temperature, over heating load,big error for irradiance, auto shut-down protection when opening door.
■ Touch screen and user-friendly operation interface allow operator to set the test parameters and monitor all the test process easily.
■ Specimen mounting and evaluation is fast and easy With unique slide-out specimen tray
■ Real-time data can be collected and recorded. The incidental USB connector allow users to copy the test data into a USB drive, achieving unattended operation.
