5Composite salt spray test chamberIntroduction to Structural Design

1. The appearance design of this salt spray corrosion test chamber is beautiful, the structure is reasonable, and the lines are smooth and natural. High quality materials are selected for the inner lining of the box2205 corrosion-resistant stainless steel, shell made of 2205 stainless steel or galvanized sheet spray painted (color 7035), with a smooth and bright appearance, corrosion resistance, easy cleaning, no leakage, good temperature resistance, high strength, and no deformation. Various auxiliary accessories and facilities are also made of corrosion-resistant materials.

2. Open top door, observation window can observe the condition of the indoor specimen from the outside without affecting the test results; The top of the box is designed toThe optimal top angle is 110 degrees to prevent condensation generated during the test from dripping onto the sample and affecting the test results.

3. The heating of the box is fast and the temperature distribution is uniform. The sample rack is designed with two layers of upper and lower layers according to national standardsTilt at 15 degrees and 30 degrees, or use a hook method.

7Composite salt spray test chamberSpray control system

1. Pneumatic spray mode, the air pressure is regulated in two stages: the first stage is the intake pressure, which is generally regulated as0.2~0.3MPa； The second level is the spray pressure. In order to meet the precision requirements of spray pressure in the new standard, the customized high-precision pressure gauge is selected for the spray pressure gauge of this equipment.
