The aerospace industry requires industrial dehumidifiers. Moreover, in the aerospace industry, industrial dehumidifiers play a crucial role. This article will explain in detail why.
1. Why does the aerospace industry need dehumidifiers
The aerospace manufacturing and assembly environment has extremely high requirements for air humidity, as high humidity can lead to the following problems:
Corrosion and oxidation of metals
Aircraft and spacecraft components are mostly made of high-precision materials such as aluminum alloy, titanium alloy, carbon fiber, etc. Excessive air humidity can accelerate oxidation and corrosion, affecting the lifespan and safety of components.
Electronic components become damp and fail
Aviation electronic equipment, navigation instruments, control systems, etc., contain a large number of circuit boards and sensors, which are prone to short circuits or accuracy drift when exposed to moisture.
The curing quality of composite materials is affected
Composite materials such as carbon fiber and resin are extremely sensitive to temperature and humidity during production and curing processes. Excessive humidity can cause bubbles, delamination, and a decrease in strength.
Spraying and coating processes require a constant humidity environment
Aircraft spray painting or anti-corrosion coating requires a strict humidity range (usually 40-60% RH) to ensure adhesion and surface quality.
Storage and testing environment control
Storage spaces for aviation components, rocket propellants, precision instruments, etc., all require a dry environment to avoid moisture absorption, deterioration, or performance degradation.
