Precision Salt Spray Testing Machine Hardware Salt Spray Corrosion Testing Machine Salt Spray Test Chamber

The salt spray test chamber can assess the ability of certain products to resist salt spray corrosion by assessing the ability to resist salt spray corrosion of materials and their protective layers, as well as comparing the process quality of similar protective layers; thereby evaluating their corrosion resistance, thereby Determine parameters such as its applicability and lifespan. Salt spray test chambers are usually used in electronic components, automobiles, ships, aviation, aerospace, furniture and other fields to ensure the adaptability and durability of products to the salt spray environment.

Product Description

Introduction

Principle

1. The working principle of the salt spray test chamber is to compress the corrosive solution into an air spray, spray it on the sample, and try to wrap the spray on all sides of the sample. This test can be performed continuously or cyclically until corrosion occurs on the sample. Then record the corrosion time as the corrosion resistance of the sample. The longer the time, the better the corrosion resistance of the sample.
2. The corrosion solution in the general salt spray test chamber is mainly a 5% concentration sodium chloride solution or 0.26 grams of copper chloride per liter is added to the sodium chloride solution as a salt spray corrosion solution. In addition, the salt spray test chamber can independently adjust the deposition and spray volume of salt spray to ensure constant test temperature, convenient operation, and stable test environment. Therefore, it is often used to test the corrosion resistance of daily necessities or industrial products.
3. The test chamber can reach any temperature point from normal temperature to 50°C in the test working space and maintain it constant. Conduct a salt spray corrosion test on materials or products in a box with a specified volume and with constant temperature and relative humidity. The material used to manufacture this equipment is imported corrosion-resistant PVC plastic sheet, which does not react with salt-containing solutions or acidic salt-containing solutions and does not affect the test results. This equipment is designed to balance internal and external pressures during operation, and the salt spray settles freely in the box, and can be adjusted to the range specified by the standard.
