1.  Function

Salt spray test chamber is used for the quality inspection and corrosion resistance test of a variety of materials, including metal plating, metal, electronic components, chemical coatings, paint, automobiles, motorcycles, metal ware, screws, springs, magnetic materials, organic and inorganic coating, anodizing, anti-rust oil industry etc. after the surface treatment.

2.  Technical parameters

a)  Temp. range: RT+10℃ ~ 55℃ (temperature up to 50C, thickening PVC or PP material is recommended )

b) Humid. range: ≥93%R.H

c) Testing method: Neutral salt spray test (NSS test), acetic acid salt spray test (AASS test), salt spray test (SS test), copper accelerated acetic acid salt spray test method for salt spray test (CASS test) and so on; (For CASS test, we recommend the PP material chamber with high temperature resistance)

d) Specimen holder: It can meet the tilt test at 15, 25 angles optional

e) Air compressor: V-0.013/12.5(Customer provided); discharge pressure:1.25M; flow amount: 0.13m3/min

3.  Material of machine body

a) Salt spray chamber adopts the quality PVC reinforced hard plastic plate, the surface is smooth and anti-aging, anti-corrosion;

b) Without any FRP material produced on the surface because of discoloration fibrosis. Plastic structure of the chamber is better to meet strong acid salt spray test under long-term without any damage.

c) Cover is imported transparent impact-resistant plate which is convenient to test specimen when test, that can cover and the box with a water seal to prevent leakage of salt spray.

4.  According to CSN, JIS, ASTM standards, can be set to constant temperature control:

(a) Brine spray test: NSS (neutral);

· Temp. inside chamber: 35 ℃ ± 1 ℃

· Pressure air bucket: 47 ℃ ± 1 ℃

(b) Corrosion resistance test: CASS (copper acceleration), AASS (acid)

· Temp. inside chamber: 50 ° C ± 1 ° C

· Pressure air bucket: 63 ℃ ± 1 ℃

5.  Watering system.

It adopts the auto watering system, supply water when lack of water.

6.  Heating system

Test temperature inside the cabinets is heated humidification water jacket, the heater adopts advanced titanium protective tube, built-in nickel-chromium alloy infrared heater core. Heating up fast, uniform temperature distribution; and saves about one half of the power compared to FRP tank jacketed heating.
