Mixed gas corrosion test chamberTesting the corrosion of materials by corrosive gases using gas precision control technology. It can be used to assess the ability of materials and their protective layers to resist mixed gas corrosion, as well as to compare the process quality of similar protective layers. It can also be used to assess the ability of certain products to resist mixed gas corrosion.

The mixed gas corrosion test chamber can reach any temperature point between 15-60 ℃ in the test workspace and maintain a constant temperature. Continuously introducing a certain concentration of binary mixed gas into a box with a specified volume to maintain a constant concentration, temperature, and relative humidity of the material or product.

The mixed gas corrosion test chamber is used to evaluate the resistance of electronic components and components with metal or organic coatings to pure or SO2, H2S, NO2, Cl2, and O3 mixed gases. It can prevent the formation of water droplets on the inner wall of the test chamber so that the gas concentration is not affected. Its automatic gas concentration control system ensures test reproducibility by measuring optical density.

The structure of the mixed gas corrosion test chamber is made of PVC reinforced hard plastic plates for both the box body and the inner liner, with a smooth and even surface, and is resistant to aging and corrosion; The box door is made of fully transparent tempered glass, which is convenient for observing the test condition of the test sample during testing; Two box doors are sealed with silicone sealing strips to prevent the leakage of hydrogen sulfide gas; The top of the box is designed in a tilted manner to facilitate the condensation water to slide down the wall panel.

Hydrogen sulfide gas is first measured by a specially designed measuring device to determine its volume, and then enters the interior of the box. The measuring device is specially designed; Hydrogen sulfide gas enters the partial flow pipeline inside the box and diffuses evenly; There is a pressure relief valve inside the box, and the air outlet is connected to a filter; The residual gas in the box is designed for alkali atomization neutralization and activated carbon physical adsorption filtration.

The laboratory can install equipment and gas cylinder leak alarm and automatic filtration devices; Use steel cylinder gas and pressure reducing valve; Heating and humidification is the heating method for the inner tank sink, which heats up quickly and distributes temperature and humidity evenly.
