Description
Technical Field
The utility model relates to an automobile aging detection technical field specifically indicates an automobile exterior trim corrosion behavior simulation evaluation device.
Background
Exterior automotive parts are often aesthetically designed with surface treatment processes to reflect a brighter metallic luster to maximize consumer appeal, two common types of surface treatment including electroplated bright chrome and high bright anodization. However, the coatings formed by the two types of surface treatment methods cannot ensure complete appearance performance in a high-temperature, high-humidity and high-corrosion climate environment, and defects such as light loss and corrosion are caused, so that after-sale complaints are caused and the brand image is influenced. There is therefore a need for an apparatus to perform accelerated simulation of parts in a similarly harsh environment to assess after-market risk.
At present, automobile factories mostly adopt a temperature and humidity aging box to simulate different climate temperature and humidity changes, adopt a salt spray box to simulate atmospheric salt corrosion, and finish two tests respectively and independently. However, the influence of other influencing factors such as dust, acid rain and the like on the two coatings under the natural environment is not really and objectively verified, so that the test result is often more ideal than the actual situation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming the defects existing in the prior art and providing an objective and real corrosion performance simulation evaluation device for simulating the automobile corrosion environment.
In order to achieve the above object, the utility model provides an automobile exterior trimming part corrosion behavior simulation evaluation device, its characterized in that: the device comprises a closed box with a part to be detected arranged inside, wherein a water tank and a heater are respectively arranged in the closed box, a spray head communicated with a corrosive liquid spray can is also arranged in the closed box, the water tank is positioned at the bottom of the closed box, and the spray head is positioned right above the part to be detected.
Further, the inner wall of the closed box is fixedly provided with a storage rack for placing the parts to be tested, and the storage rack is provided with a vent hole.
Furthermore, the spray head is communicated with the corrosive liquid spray can through a guide pipe, and the guide pipe is also communicated with a control valve.
Further, the whole closed box is positioned in the oven, and the heater is arranged on the inner wall of the oven.
The utility model has the advantages that: and the authenticity of the test environment and the test result is improved. The device integrates the three major influencing factors of temperature, humidity and corrosivity into one device, so that the part to be tested is positioned in the environment of the three major influencing factors simultaneously, the measuring environment is more truly accordant with the high-temperature, high-humidity and high-corrosivity climatic environment, the measuring and evaluating result in the environment is more accordant with the actual situation, and the authenticity of the test is improved.

The utility model discloses in integrating this three big influence factors of temperature, humidity and corrosivity to a device, make the part that awaits measuring be located the environment of these three big influence factors simultaneously, make the more real climatic environment who accords with the high corrosivity of high temperature and high humidity of measuring ring border, consequently the result of measurement and aassessment accords with actual conditions more in this kind of environment, has improved the authenticity of test.
When the climatic environment of tropical rainforest high temperature, high humidity, multiple salt, multiple acid rain and multiple dust in southeast Asia is simulated, the test parameters are designed as follows:
the temperature change was 12 hours for 20 cycles. The temperature control process of one cycle is as follows: firstly keeping the temperature at 10 ℃ for 4 hours, then heating to 40 ℃ at the speed of 0.5 ℃/min and keeping the temperature for 4 hours, heating to 80 ℃ at the speed of 0.5 ℃/min and keeping the temperature for 4 hours, and finally cooling to 10 ℃ at the speed of 0.5 ℃/min.
Spraying 30 ml of corrosive liquid on the surface of the part before each period, cleaning and drying the surface of the test piece by using clean water in each period after 10 periods, and recording the surface condition of the test piece.
The surface condition evaluation includes three aspects: oxidation state 0-5 grade, foaming state 0-5 grade and color change 0-5 grade. The evaluation of the corresponding level can be searched in the corresponding enterprise standard, the surface state after the final experiment is finished is not higher than 1 level in three aspects, and the risk of appearance failure of the part in the specific climate environment can be considered to be small.
