Problems solved by technology

[0005] The purpose of the present invention is to provide a multi-functional corrosion test box for the problems of large volume of the salt spray box in the existing salt spray corrosion test box, the need for an air compressor outside the box to supply the spray with compressed air, and the single function of the existing salt spray box. The salt spray test chamber changes the traditional spray principle and adopts the principle of ultrasonic spray to simplify the experimental equipment, and at the same time, it can also carry out corrosion tests such as constant temperature and humidity and alternating dry and wet.

Embodiment 1

[0019] Example 1: Neutral salt spray test (GB10125-1997 "Artificial Atmosphere Corrosion Test Salt Spray Test")

[0020] 1. configuration mass fraction is the sodium chloride solution of 5%, adds in the brine tank 5; Regulate the ultrasonic oscillation power on the control panel 4, after the salt spray tank runs 24 hours, make the measuring cylinder 6 outside the observation box collect every hour Saline volume reaches 1-2ml / 80cm 2 , pH 6.5-7.2.

[0021] 2. Put the sample to be tested on the card slot on the sample table set frame. If the sample is a large-size plate or part, you need to disassemble one or several belt slots, and add a special card slot baffle to make the large test sample in an appropriate location.

[0022] 3. Adjust the temperature button on the control panel 4 to keep the temperature in the exposed area of ​​the salt spray box at 35°C.

[0023] 4. The test period should be selected according to the relevant standards of the tested material or product, a...

Embodiment 2

[0025] Embodiment 2: constant temperature and humidity experiment

[0026] 1. Add deionized water into the water tank 5, replace the observation cover 3 with a special exhaust fan, and the fan is controlled by the control system.

[0027] 2. According to the needs of the test, set the humidity value and temperature value on the control panel 4.

[0028] 3. Put the sample to be tested on the card slot on the sample stage assembly frame. If the sample is a large-size plate or part, you need to remove one or several tape slots, and add a special The slot baffle keeps the large sample in a suitable position.

[0029] 4. The test period should be selected according to the relevant standards of the tested material or product.

[0030] 5. After the test, clean the main tank and the brine tank with clean water.

Embodiment 3

[0031] Embodiment 3: wet and dry alternate experiment

[0032] 1. Configure a sodium chloride solution with a mass fraction of 3.5%, and add it to the brine tank 5; add deionized water to the brine tank

[0033] 5, the observation cover 3 is replaced by a special exhaust fan.

[0034] 2. According to the needs of the test, set the periodic interrupt timer on the control panel 4. like simulating some kind of marine corrosion

[0035] Environment, dry environment and wet environment have a cycle of 12 hours, which can be set on the cycle interrupt timer

[0036] Room, humidity and temperature values; for example, the humidity of the humid environment is 80%, the temperature is 25°C, and the time is 12 hours, while the dry environment

[0037] The drying environment is 5% humidity, 40°C, and 12 hours.

[0038] 3. Put the sample to be tested on the card slot on the sample stage assembly frame. If the sample is a large-size plate or part, it needs to be disassembled

Abstract

The invention relates to a multi-purpose salt fog test box belonging to the technical field of material analysis equipment. The multi-purpose salt fog test box comprises a main box body (1), a box cover (2), an observation cover (3), a salt water box (5) and a control device panel (4), wherein the main box body (1) is provided with a sealed water tank and internally comprises a salt fog collector(6-1), an ultrasonic salt fog generating device (8), a conduit (8-1), a heating and temperature warning device (9), a temperature sensor (10), a humidity sensor (11), support blocks (12-1), (13-1) and (14-1), a diaphragm (13), a sealing diaphragm (14) and a sample stage combination shelf (12); the external accessories of the test box comprise a box cover handle (2-1), a salt water box cover (5-1), a salt fog metering device (6), waste liquid drain pipes (5-2) and (8-2), a pipe (14-2) and a hinge part (7). The multi-purpose salt fog test box adopts the principle of the ultrasonic spray, omits the air compressor in the traditional salt fog test box, simplifies the test box and can be used for corrosion tests under constant-temperature-and-humidity conditions, alternating wetting and drying conditions and other conditions.

Description

technical field [0001] The invention relates to a multifunctional salt spray test chamber, which belongs to the technical field of material analysis equipment. It is especially used for the salt spray performance test of metal materials, protective layers, parts, electronic components and industrial products, and can also be used for constant temperature and humidity and alternating dry and wet corrosion tests. Background technique [0002] Salt spray corrosion is a common and most destructive atmospheric corrosion. The main corrosion component is sodium chloride in the ocean, which mainly comes from the ocean and inland saline-alkali areas. The corrosion of salt spray on the surface of metal materials is caused by the electrochemical reaction between chloride ions penetrating through the oxide layer and protective layer of the metal surface and the internal metal. At the same time, because chloride ions contain a certain amount of water and energy, they are easily adsorbed...
