A table teaches you how to properly use the salt spray test chamber
We all know that the first use of the salt spray test chamber has a lot of attention, but it is also necessary to do a good job. So, what should we pay attention to before starting the salt spray test chamber, how to prepare adequately? The following table is a small series of preparations for the salt spray test chamber before starting. Interested friends may wish to come together. Let's see.
Gas source
Check the connection between the gas source and the stainless steel barrel; whether the connection between the gas source and the sprayer is off, to prevent the gas from overflowing or the shortage of gas supply.
funnel
The funnel inside the box is built, and the connection between the funnel and the mist collector is checked whether it is smooth and intact, and the collection of salt spray settlement cannot be affected.
sample
Open the lid and place the sample correctly on the sample holder in the working chamber (10% from the surrounding chamber wall). Keep a certain distance between the sample and the sample, so that the exposed surface area of ​​the sample is >98%, and then close the lid.
Water seal
The water seal groove around the upper part of the tank should be filled with distilled water or deionized water. It should not be too full, not too little. When the lid is closed, the water and salt spray are not spilled.
Water storage tank
Check that the water pipe between the storage tank and the sprayer in the work chamber is well connected. Add the prepared salt solution (usually prepared at a concentration of 5%) to the storage tank. Add distilled water or deionized water to the bottom of the heating tank in the bottom of the studio to prevent the box from aging and aging.
Fog tube
Check the fogging condition of the exhaust pipe at the rear of the cabinet; whether the air pipe is off, whether the outlet is connected to the sewer; whether the pipeline is blocked; so as not to affect the salt spray.
Stainless steel barrel
Add distilled water or deionized water to the stainless steel barrel. Open the bleed valve and the saturator water supply valve before adding water. The water level should be 4/5 of the water level glass box. When adding to the specified water level, the deflation must be turned off. Valve while closing the saturator water valve. Due to long-term test, the water content of the saturator is evaporated. When the water level is reduced to 2/5, the water should be replenished in time to prevent the heating tube from being burnt due to lack of water, and the saturator and internal heating point components are baked.
