Problems solved by technology

Under the action of the wind, the spray solution often deviates from the sample area, resulting in some samples not being sprayed or spraying unevenly, thereby affecting the effect of the accelerated corrosion test and the correctness of the test evaluation results, and at the same time causing adverse effects on the surrounding test environment. influences
The use of time relays to control timing spraying has caused two other adverse consequences: one is to form a thick water film on the surface of the sample

Embodiment Construction

[0030] Specific embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0031] An accelerated environment test box comprises a box body 1 and a transparent cover plate 2, and a mobile spraying system is arranged in the box body 1. Mobile misting systems include:

[0032] The spray device is used to spray the samples in the test chamber, including a liquid storage tank, a water pump with a water inlet pipe and a water outlet pipe, and a spray pipe with a nozzle. The water inlet pipe is connected to the liquid storage tank, and the water outlet pipe is connected to the spray pipe ;

[0033] The moving device is used for the spray tube to move in the box body 1, including two driving gears 3 oppositely arranged at one end of the test box and connected through the cross coupling 13, and oppositely arranged at the other end and connected through the cross coupling 13 Two driven gears 4, the driving gear 3 and the driven gear...

Abstract

The invention discloses a testing box for an accelerated environment, which comprises a box body (1) and a cover plate (2) hinged on the box body; and the box body (1) is internally provided with a movable spraying system. In the invention, the spraying is not affected any more by wind and rain in the external environment, the problems of non-uniform spraying, under-spraying and over-spraying andinfluence on ambient environment are solved, and the detection data is more uniform and reliable.

Description

technical field [0001] The invention relates to a test device for atmospheric corrosion or anticorrosion performance measurement, in particular to an accelerated environment test box. Background technique [0002] At present, when conducting natural environment tests, an open test device with periodic spraying is often used. The sample is placed under the spray head, and the time relay is used to control the timed and open spray. Under the action of the wind, the spray solution often deviates from the sample area, resulting in some samples not being sprayed or spraying unevenly, thereby affecting the effect of the accelerated corrosion test and the correctness of the test evaluation results, and at the same time causing adverse effects on the surrounding test environment. influences. The use of time relays to control timing spraying has caused two other adverse consequences: one is to form a thick water film on the surface of the sample, and the maximum atmospheric corrosi...
