High quality SUS304 stainless steel with surface of electrostatic injection, material thickness of 1.5mm

3.3 Internal body material

Use the acid-base resistant material SUS316L # stainless steel.Material thickness is 1.5mm

3.4 Insulating layer

A hard, polyurethane foam insulation layer was used.

3.5 Studio Top

In order to prevent the studio top condensate from dropping directly on the test product; set the 120-degree diagonal baffle on the studio roof.

3.6 Studio floor board

Reinforced plate (several reinforced sleepers built in) bearing 1500kg/m (uniform load)

3.7 Entrance door

The door adopts double door structure;

3.8 observation window

The gate has 2 observation windows, size: 400,500 mm (wide and high) hollow resistance film heating and frost prevention observation window

3.9 Test the lead holes

One φ100mm test hole was set on the left side of the box with a dedicated lid

3.10 Pressure balancing device

Two balance windows are set at the top of the studio to balance the studio with the external air pressure;

3.11 Guide track and position limit device

Guide function track is set on the left and right sides of the test box, and position limit function device is set at the bottom of the rear end.

3.12 cart

Load cart

3.13 Lighting

Two LED strong light lighting, projected to the workshop through the transparent window at the top of the studio; independent switch control

3.14 Condensate  outlet

Lead hole with condensate of air conditioning room and condensate of unit;

3.15 spill port

A condensate drainage ditch is provided around the studio, and the condensate drain is discharged through the overflow hole to the wastewater treatment area; (the pipeline user of the equipment to the wastewater treatment area is responsible)

4. Saline spray simulation system

4.1 Salt fog settling amount

1.0~3.0ml/80cm2.h (adjustable)

4.2 PH of acid and base

Between 6.5~7.2

4.3 spray nozzle

Made of special quartz glass nozzles, the special customized baffle spray device changes the settlement amount of salt spray by adjusting the angle of the baffle and the size of the air flow

4.4 Spray method

Airflow spray, continuous / gap arbitrary

4.5 Brine tank

Corrosion-resistant salt water tank shall be provided.(plastics)

4.6 Continuous spray time

The test tank needs a large salt tank to allow continuous spray for up to more than 60 hours without adding salt water.

4.7 Spray system

The function of the spray device is to saline supply system, using the high pressure air, high speed from the nozzle injection, through the siphon principle of the brine up and air mixed to produce blurred fog, because the fog contains some unfoggy water droplets, so the spray can not be directly introduced into the laboratory body, and should first hit a salt spray baffle, fog or excess salt mist back, so that the spray is the real fine mist without water droplets.The size of salt fog settlement is directly related to the level of salt water supply and gas supply pressure and the Angle of the baffle.

4.8 Adjustment of air pressure

Dual pressure adjustment and protection for continuous or periodic spray.Intake pressure is controlled at 0.2~0.4Mpa.

4.9 Spray pressure

Controlled at 0.05~0.17MPa or spray pressure: 1.00±0.01kgf/cm2 (the air compressor is configured by Party B).

4.10 Salt fog collector

A funnel is set on the equipment side to be connected outdoors through the hose to observe the settlement amount and detect the PH value of acid and base
