Some preparations for small salt fog cavitation test chamber test

2022-07-18

Small salt spray corrosion test chamber is a method of selecting salt spray corrosion to see the reliability of inevitable corrosion resistance of the sample sample, and the salt fog refers to a dispersion system consisting of salt microtaraphic droplets in the atmosphere. One of the three defense series of artificial environment, many company products need to mimic the destructiveness of the ocean surrounding climate on products.

We use small salt spray corrosion test chambers to know which experiments should be prepared before doing salt fog experiments:

1, the bottom of the working room is added to the water tank to add distilled water or deion Water to prevent the cooker when heated.

2, the air saturator (stainless steel bucket) is involved in distilled water or deionized water, and then turn off the discharge valve and saturate before adding water, and the water level height is the 4/5 position of the water level glass box. Therefore, when adding to the regular water level, it is necessary to enclose the air valve to close the saturated heater. Because long-term experiments, the saturated water is evaporated, when the water level is lowered to 2/5, it should be hydrated in time to avoid the air burning of the heating tube due to water shortage, and the barbecue satuid and the internal heating point element.

3, the water sealing groove near the upper portion of the box should participate in appropriate distilled water or deionized water, should not be full, do not be too small, in the closed box cover, water and salt fog are overflow Good.

4, check the water tube between the water storage tank and the operating room sprayer is not a shortage, and the manufactured salt solution (usually manufactured by 5% concentration) will participate in the water storage tank.

5, the funnel inside the box, check the hunter and intensive the title between the set of intensivers, is not a shortage, never affect the collection of salt fog settlement. 6, check the spray pipe spray in the rear of the box; the trachea is not falling, the exit is not to the sewer; the pipeline is not blocked; avoiding the emissions of salt fog.

7, open the cover, place the sample correctly on the sample frame in the working room (10% from the surrounding ventricular wall), the sample is insisting on a certain interval between the sample, so that the surface area of u200bu200bthe sample is exposed to the surface area gt; 98% , Close the cover.

8. View the tone of the gas source and the satuid; the tone of the gas source and the sprayer is not dropped, avoiding the shortage of gas spillage or the lack of gas supply.
