Dry ice cleaning machine<\/a><\/strong> uses solid CO\u2082 pellets that are accelerated by compressed air and sprayed onto surfaces to remove contaminants.<\/p>

Dry ice sublimates instantly upon contact with the surface, meaning it turns directly from solid into gas without leaving any residue.<\/p>

Three Core Principles of Dry Ice Cleaning<\/h2>

1. Kinetic Impact (Momentum Effect)<\/h3>

High-speed dry ice particles hit the contaminant layer and create an instant impact force that breaks the bond between dirt and the surface.<\/p>

Key point:<\/h4>

Dry ice is much softer than metal or most equipment surfaces, so it removes contaminants without scratching or abrasion.<\/p>

2. Thermal Shock (Brittle Fracturing Effect)<\/h3>

Dry ice has a temperature of approximately -78.5\u00b0C, which rapidly cools contaminants upon contact.<\/p>

Result:<\/h4>

Dirt becomes brittle and cracks, separating from the substrate due to thermal stress differences.<\/p>

3. Sublimation Expansion (Micro-Explosion Effect)<\/h3>

When dry ice hits the surface, it instantly sublimates, expanding nearly 700 times in volume.<\/p>

Effect:<\/h4>

This rapid expansion lifts contaminants from beneath, enhancing cleaning performance.<\/p>

Why Does Dry Ice Cleaning Machine Not Damage the Surface?<\/h2>

1. Non-Abrasive Medium<\/h3>

Dry ice is a soft cleaning medium, unlike sand or steel grit, so it does not cause surface wear.<\/p>

2. No Water or Chemical Damage<\/h3>
