Salt Spray Corrosion Test Chamber Models & Technical Specifications

Configuration of Salt Spray Corrosion Test Chamber

Materials:

1. Durable Test Chamber Construction

The test chamber’s inner and outer boxes are crafted from high-quality, 8mm-thick grade A PVC polyethylene boards.  The.se boards offer exceptional:

• Chemical resistance: Withstanding exposure to acidic and alkaline substances.
• Heat tolerance: Withstanding temperatures of up to 78°

This robust construction ensures the test chamber’s longevity and reliability, even in demanding environments

2. Advanced Sealing Cover Design

The test chamber’s sealing cover is constructed from high-quality, 6–8mm-thick grade A polyethylene board.

This design ensures:

• Chemical resistance: Effective resistance to acidic and alkaline substances.
• Heat tolerance: Reliable performance up to 78°C
• Intelligent Condensate Management

The cover’s carefully designed 106-degree angle prevents condensate from dripping onto the sample, ensuring unbiased test results.

• Enhanced Visibility

A transparent observation window is integrated into the front cover, providing clear visibility of the sample during testing.

3.Convenient and Secure Test Drug Refill System

The test drug refill bottle features a concealed design, allowing for efficient and secure refilling. Once the saline mixture is prepared, it’s easily refilled through the test drug inlet, flowing directly into the saline reservoir without requiring the lid to be opened.

Key Benefits:

• Easy observation: Saline levels can be conveniently monitored through the side of the reservoir.
• Simple cleaning: The design enables effortless cleaning, minimizing the risk of contamination.

Durability: The refill system is designed to be robust and resistant to damage, reducing the likelihood of rupture

4. Adjustable Test Room Shelves

The test room shelves feature a plane indexing frame, allowing for flexible placement at two optional angles

• 15 degrees: For gentle, low-intensity testing
• 30 degrees: For more pronounced, high-intensity testing
• Uniform Fog Distribution

The shelves are designed to ensure that the fog direction and distribution are consistent on all four sides, providing reliable and repeatable test results

5.Temperature Control Settings for Corrosion Testing

Our temperature control system allows for precise settings according to various international standards, including CSN, JIS, and ASTM.

• Salt Spray Testing
• NSS (Neutral Salt Spray) and AASS (Acetic Acid Salt Spray):
• Laboratory setting: 35°C ± 1°C
• Pressurized air drum setting: 47°C ± 1°C

6.Air Supply System and Spraying Methodology

Air Supply System

The air supply system features a two-stage pressure adjustment:

• Primary adjustment:
• 2kg/cm² with imported air filter featuring a drainage function
• Secondary adjustment:
• 7~1kg/cm² for precise control

Spraying Methodology

Our spraying system employs the Bernoulli principle to ensure:

• Uniform atomization: Consistent brine absorption and atomization, free from crystallization or clogging.
• Continuous testing: Supports both continuous and intermittent spray per standard requirements.

Nozzle Design

The nozzle is crafted from quartz glass, featuring:

• Brine filter: Prevents clogging in the salt water feed pipe
• Long-lasting performance: Operates for up to 4,000 hours without blockage from crystallized salt

Spray Volume Adjustment

The system uses 50ML glass collection measuring cups (1 or 2 sets depending on the model), featuring:

• Convenient observation: Embedded installation for easy monitoring
• Precise control: Adjustable spray volume to meet national standards (1-2ml/80cm²/h, averaged over 16 hours)

7. Heating System

Our heating system uses steam direct heating with titanium alloy tubes, ensuring fast temperature rise, strong corrosion resistance, and stable, accurate test results.

• Heating Method:
• The equipment adopts steam direct heating to raise temperature efficiently within the chamber.
• This method ensures rapid and uniform temperature rise, reducing standby time before testing begins.
• Heating Tube Material:
• Heating tubes are made of titanium alloy, which offers excellent resistance to strong acids and alkalis.
• This enhances durability and ensures reliable long-term performance under corrosive conditions typical of salt spray tests.

• Maintenance Access:
• The rear side of the chamber includes a dedicated maintenance port for easy access to the heating tube.
• This design facilitates convenient replacement and routine servicing, minimizing downtime and improving user experience.

8.Key Components and Features

• Saturated Barrel
• Cylindrical PP high-pressure tube: 160mm diameter, 10mm thickness, hard, and pressure-resistant
• Capacity: 5KG pressure-resistant, exceeding inlet pressure by 2KG
