Corrosion Simulation Technology

Salt Spray Corrosion Test Chamber

A professional-grade environmental simulation system designed to evaluate the anti-erosion resistance of treated material surfaces. It provides critical data for products treated with electric plating, anodizing, and organic coatings through standardized saline and corrosive mist exposure.

Product Overview

The ASLI Salt Spray Chamber is engineered for high-precision corrosion testing across multiple industrial standards (NSS, ACSS, CASS). By controlling lab and pressure bucket temperatures alongside precise saline concentrations, it accelerates the aging process to verify the long-term durability of protective coatings.

Performance Advantages

Precision Atomization

Achieves a standardized spray volume of 1.0-2.0ml/80cm²/h, ensuring uniform distribution of corrosive mist across all samples.

Flexible Programming

Supports both continuous and programmable spraying cycles to accommodate specific research requirements and international protocols.

Dual-Mode Thermal Control

Independent temperature stabilization for the laboratory chamber and the pressure bucket to support NSS, ACSS, and CASS testing methods.

Scalable Capacity

Available in a wide range of internal dimensions from 600mm to 2000mm in width to test components of varying sizes and quantities.

Core Systems

Corrosion Environment

Chemistry: Utilizes a 5% NaCl solution. For CASS (Copper-Accelerated Salt Spray) testing, 0.26g of CuCl2H2O is added per liter to simulate highly aggressive environments.

Pressure Management

Stability: Operates with a compressed air pressure range of 1.0~6.0 Kgf, maintaining the pressure bucket at 47°C or 63°C depending on the selected test protocol.
