Background technology
Salt air corrosion is a kind of atmospheric corrosion of common and most destructive, and main corrosion composition is the sodium chloride in the ocean, its main source Yu Haiyang and interior ground varieties in saline-alkali areas.Salt fog is because the electrochemical reaction that the oxide layer on chlorion penetrating metal surface and protective layer and interior metal occur causes to the corrosion of metal material surface.Simultaneously since chlorion contain certain water and can, easily be adsorbed on the space, slit of metal surface and reach for the oxygen in the oxide layer, insoluble oxide is become the chloride of solubility, passivated surface is activated and product is damaged.
Salt-mist corrosion tester is a kind of equipment of examining metal material and protective seam or industrial products decay resistance under the simulation salt mist environment that utilizes, and mainly is to simulate a bad border of gedanken experiment that accelerated corrosion is required for the experimenter.Under the Natural Exposure environment, some product is carried out salt-fog test, wait to corrode possibly some months even 1 year, and under manual simulation's salt mist environment condition, test, as long as several hours or tens hours can reach similar result.Manual simulation's salt-fog test comprises that again neutral salt spray test, acetic acid salt spray test, mantoquita accelerate acetic acid salt spray test, alternation salt-fog test.Especially for the equipment that metal material, protective seam, parts, electronic devices and components and industrial products is carried out salt fog resistance performance test, but also availablely be used for doing constant temperature and humidity and alternation of wetting and drying corrosion test.
At present, the spraying principle of experimental provision is to enter nozzle after utilizing the gas process purification of air compressor generation, preheating, reduced pressure treatment, and the salt solution make-up system is with salt solution supply nozzle suction hose; During spraying, pressurized air is gone out nozzle, above suction hose, produce negative pressure, salt solution is under the effect of negative pressure, penetrated by fluid injector rapidly, the salt fog of ejection is diffused into and simulates salt mist environment in the casing, and its shortcoming is that the experimental provision volume is large, case external demand air compressor device pressurized air is supplied with spraying, and existing experimental provision function singleness.
The utility model content
The purpose of this utility model is that the experimental provision volume that exists for existing salt-mist corrosion tester is large, case external demand air compressor device pressurized air is supplied with spraying, and the problem of existing experimental provision function singleness, and provide a kind of multifunction test unit, change traditional spraying principle and adopt the ultrasonic atomization principle, to simplify experimental provision, can also carry out the corrosion tests such as constant temperature and humidity and alternation of wetting and drying simultaneously.
A kind of mist generating device of multifunction test device, mist generating device comprises U-shaped container, middle and upper part in the first side of U-shaped container arranges the first shower nozzle, it is corresponding with the first shower nozzle mouth that what arrange is the second shower nozzle, a spraying baffle plate is set directly over the first shower nozzle and the second shower nozzle, the gases at high pressure of the first shower nozzle ejection blow to the salt solution of the second shower nozzle ejection on the spraying baffle plate, form mist
The wire of mist generating device links to each other with relevant control assembly in the control device panel by the brine tank bottom half; Be positioned at top, main box rear end and the chamber interior wall centre position be temperature sensor and humidity sensor, they by high temperature resistant anti-corrosion wire respectively with the control device panel in temperature-controlling module link to each other with the humidity Control Component; The below of temperature sensor and humidity sensor is sample stage group frame, and sample stage group frame fixes support by the first back-up block of below, and the first back-up block welds the rear and front end in main box; The following of sample stage group frame is dividing plate, and dividing plate is by the second back-up block, fixed support, and the salt fog cylinder of mist generating device passes the centre of dividing plate; Be seal diaphragm below the dividing plate, seal diaphragm is by the 3rd back-up block fixed support, and dividing plate requirement and cabinet wall and salt fog cylinder pass the sealing of central partition plate position; Between dividing plate and seal diaphragm is heating tube and temperature pre-warning device, and heating tube and temperature pre-warning device are connected with associated component in the control device panel respectively by the main box tank wall by the heat-proof corrosion-resistant wire.
