Problems solved by technology

However, the inner wall of the current condensation water test chamber (especially the inner wall of the top) is easy to accumulate water droplets, and the water droplets will drip onto the tested sample, causing (local) damage to the tested sample and unacceptable experimental results.
Moreover, in order to heat the air to meet the air temperature requirements of the test, the current condensate water test chamber generally adopts the method of circulating air, which will easily cause the surface of the sample to be difficult or even unable to form condensation, which does not meet the test requirements.
The above defects lead to the low accuracy of the test results of the current condensate test chamber

Abstract

The invention relates to a condensate water testing device and a testing method adopting the same. The testing device comprises a mounting base as well as a test box and a digital display controller which are mounted on the mounting base, wherein a box door is arranged on one front surface of the test box; a detachable sample rack is arranged in the test box; an electric heating glass plate is attached to the top in the test box, a water accommodating plate for accommodating water and a heater for heating the water accommodating plate are arranged at the bottom, a temperature sensor and a humidity sensor which are in communication connection with the digital display controller are arranged above the water accommodating plate, a water receiving groove is formed below the box door and connected with the water accommodating plate through a U-shaped pipe, and a water drain valve is arranged at the bottom of the U-shaped pipe. Compared with the prior art, the accuracy of a moisture-proof test is improved by adopting multiple measures.

Description

technical field [0001] The invention relates to the technical field of sample testing, in particular to a condensed water test device and a test method using the condensed water test device. Background technique [0002] Condensation water test chamber is widely used in the determination of moisture resistance of paints and varnishes. It is used to test the paint film after the paint is painted under the condition of 100% relative humidity and condensation water on the paint film. Blister degree and changes in appearance. The sample coated with paint film is placed in the condensed water test box. Due to the radiation effect of the condensed water test box or the cooling effect of the sample itself, the temperature of the surface of the sample in the test box is lower than that of the saturated ambient air in the test box. Temperature, so that the moisture in the air will condense on the surface of the sample, so that the sample can be tested. However, the current condensa...
