Product description
This condensate (alternating) test equipment uses distilled water or Deionized water, using this test chamber, without moving the test sample in a test chamber, can achieve: two cycles (alternating) of standard atmospheric pressure constant condensate water and alternating condensate water (alternating) test effects on materials or products under test requirements. Accelerated corrosion tests the extent of damage a material or product suffers over a certain period of time. This equipment is used to assess the ability of materials and their protective layers to resist condensation water at high temperatures, high humidity and low temperature and humidity, as well as to compare the process quality of similar protective layers. It is an artificial standard atmospheric pressure constant condensation water and alternating condensation water environment test. .
Only by reasonably stipulating the environmental conditions of the product and correctly selecting the environmental protection measures for the product can the product be protected from damage during storage and transportation and be safe and reliable during use. Therefore, artificial simulated environmental testing of materials or products is an indispensable and important link to ensure their high quality. Artificial simulated environment tests are scientific summaries of actual environmental impacts and are typical, standardized, easy to use, and easy to compare.

Introduction to structural design
.The main functions of this test chamber The structural components include: box part, electrical control system, heating system, refrigeration system and condensation water system
. The shape of the box is designed with left and right structures, beautiful appearance, reasonable structure, smooth and natural lines. The outer shell of the box is made of high-quality plates imported from Taiwan, and the inner tank is made of imported high-temperature resistant plates. The appearance is smooth and bright, corrosion-resistant, easy to clean, no leakage, good temperature resistance and high strength. Various auxiliary accessories and facilities are also made of temperature-resistant and corrosion-resistant materials to make the bottom hole-shaped load-bearing sample holder plate (this material has the characteristics of temperature resistance, corrosion resistance and high load-bearing)
3. Box cover The material is imported high-quality transparent plate
. The box cover is designed to have an optimal top angle, and the opening angle is about 10 degrees.
The condition of the specimen in the room can be clearly observed. The hole-shaped load-bearing frame ensures that the condensation water generated during the test will not drip onto the sample and affect the test results
The box cover and box body are water-sealed to prevent temperature and humidity from overflowing and thus affecting the test results
br/> .The box heating design is an electric heating method for the inner tank, which is economical and environmentally friendly, with fast heating and even temperature and humidity distribution
. There is a water tank at the bottom of the test chamber, the water level is controllable, and a low water level alarm device is provided
. The evaporator for refrigeration of the test chamber doubles as a dehumidifier, which can meet the humidity requirements at different temperatures and is anti-corrosion treated
. It adopts corrosion-resistant long-axis fan motor and corrosion-resistant B multi-wing centrifugal wind wheel to achieve Strong convection, vertical diffusion circulation, and a unique air duct mechanism make the temperature and humidity in the laboratory uniform and stable.
Function introduction
Constant condensation water test
Before using the constant condensation water function, first add distilled water or deionized water to the bottom of the test chamber, evaporate the moist heat through the shallow groove, and the generated temperature is ℃℃, The relative humidity of the box can be controlled at (humidity deviation: +~R), and the steam generator and heater maintain the set temperature and humidity. They are intelligently controlled and automatically calculated to achieve the required moist and hot effect (i.e. condensation phenomenon).
Alternating condensation water test
During the alternating condensation water function, the equipment performs an automatic execution stage according to the preset temperature, humidity and time through the controller: the humid heat is evaporated through a shallow groove, and the temperature is controlled at ℃ Exchange (cycle) between ℃ and ℃~℃℃, so that the relative humidity of the box can be controlled at (humidity deviation: +~R) or R~R (humidity deviation: +~R), and the steam generator and heater maintain The set humidity is intelligently controlled and automatically calculated to achieve the required heat and humidity effect (i.e. condensation phenomenon).
