Programmable salt spray (waterproof) corrosion test chamber (2 workshops)

1、 Application of Programmable Salt Spray Corrosion Test Chamber (2 working rooms)

Salt spray corrosion special test box (export type) is a salt spray corrosion test equipment that artificially simulates oceanic climate, used for component junction boxes and back films. It refers to IEC61701-1995 (equivalent GB/T18912-2002) photovoltaic module salt spray test, which references IEC60068-1:1988 (equivalent GB/T2421-1999) standard, mainly for environmental testing of electrical and electronic products (junction boxes); The back film may have poor breathability and permeability due to the high temperature of the salt spray environment, which can cause moisture infiltration and internal changes in the component (corrosion of tin coated copper strips, blistering or even detachment between EVA, PVB and thin films or silicon wafers). It is also one of the "three defenses" (humidity, salt spray, mold) testing equipment for artificial climate environments. It is an important testing equipment for studying the adaptability and reliability of various environments in industries such as machinery, defense industry, light industry electronics, instruments, photovoltaic modules, etc. It can also be used for vinegar salt spray testing.

3、 Structural characteristics and configuration of programmable salt spray corrosion test chamber (with 2 working rooms)

The inner shell of the testing machine is made of high temperature resistant and corrosion-resistant glass steel plate or imported impact resistant PVC polyvinyl chloride plate (thickness 6mm, high temperature resistance up to 80 ℃) (shock resistant, impact resistant, smooth, easy to clean), with leakage phenomenon.

The laboratory sealing cover is embedded with a transparent hollow tempered glass large window in the middle, which can observe any angle inside the test box. The overall thickness of the box cover is 8-10mm.

The saturated bucket adopts imported SUS # 304 stainless steel high-pressure resistant bucket, with insulation effect.

Nozzle: It is made of special glass nozzle and can be used for 4500 hours. The size of spray volume and spray angle can be adjusted.

Spray tower: the spray tower is set in the middle of the laboratory to make the fog fall evenly. It can be adjusted to 1~2ml/80cm2/HR (average amount every 16 hours).

Using indirect heating method, the heating device is made of titanium alloy material

Control system: The temperature and humidity time controller adopts industrial control touch screen+PLC programmable controller control (touch button), with high control accuracy and good reliability. The display mode is LCD dot matrix color LCD screen display, with display resolution of temperature (0.1 ℃) and time (1min), temperature display range of 0-200 ℃, digital display with PID automatic calculation, and control error of ≤± 0.5 ℃.

Imported rocker type buckle switch, capable of continuous buckle up to 20000 times.
