The high and low temperature test chamber can simulate the damage of the wet environment to the material

A key advantage of the application of high and low temperature test chambers is that it can simulate the damage effect
of the outdoor wet and cold natural environment on raw materials.
When the raw materials are placed outdoors, it has been investigated that at least 12 hours a day are regularly exposed to wet and cold effects
.
Since most of these damp cooling effects are mainly manifested in the form of condensation, a DU TE condenser rationale was selected to emulate outdoor wet cooling
in the accelerated service climate aging test.
Since the time for raw materials to regain moisture outdoors is generally very long, typical circulating system condenser system software zui rarely has 4h of experimental time
.
The whole process of the condenser is carried out under the heating standard (50 °C), which will greatly accelerate the damage rate
of wet cooling to the raw materials.
Long-term, heating standards for condenser circulation systems can reasonably reproduce the condition
of raw materials contaminated by wet and cold environments than other methods such as water self-injection, pre-impregnation and other natural environments with high ambient humidity.
These temperature differences of several kilograms allow the water to continuously drop to the surface of the detected layer throughout the entire process of the condenser circulation system
.
The resulting condensate is pure and pure water
with stable characteristics.
Shanghai high and low temperature test chamber This kind of water can improve the reproducibility of test results, remove the problem of environmental pollution of water residues, and simplify the installation and practical operation
of Shanghai high and low temperature test chamber.
In the whole process of the condenser circulation system, the stainless steel sink at the bottom of the test chamber is heated to cause vapor.

The natural environment of the hot vapor maintenance chamber has 100% air humidity
outside the high temperature.
When the UV ultraviolet embrittlement characteristic tester is designed, the test plate actually constitutes the outer wall
of the test chamber.
That way, the reverse side of the test plate is exposed to
indoor air quality at indoor temperature.
The water cooling effect of indoor air quality reduces the temperature of the surface of the test plate to be measured compared
to the vapor temperature.
