Product Description

What is dry ice?
Dry Ice, a marvel in solid form, is simply the crystallized state of carbon dioxide (CO2), brilliantly crafted at a chilling -78.5 ºC. Typically, CO2 is condensed into a pristine, colorless liquid at a robust pressure of 62.50 bar. Upon encountering low-pressure environments, it swiftly solidifies, creating the dry ice we know so well.
Physical Properties: Presenting as white, crystalline beauty, dry ice sublimates gracefully at room temperature. Its substantial heat of vaporization lets it dramatically cool its surroundings under atmospheric pressure conditions. Thus, as dry ice sublimates, it elegantly captures moisture from the air, potentially liquefying and further condensing water vapor.
As dry ice sublimates, it produces a stunning visual of white smoke, a result of water vapor droplets or tiny ice crystals clinging to airborne dust. Its simple cubic crystal structure, a remarkable example of molecular crystals, holds each carbon dioxide molecule in perfect alignment.
Dry ice crystals are meticulously arranged, each positioned at the vertices and centers of a cube, showcasing a pristine stacking orientation.
Chemical Properties: Dry ice, the epitome of chemical stability, is odorless, non-toxic, and inherently safe from combustion. However, in environments with elevated carbon dioxide levels, it may provoke the respiratory system, leading to rapid breathing and, in extremes, a risk of suffocation.
Carbon dioxide, famed for its high thermal stability, exhibits a mere 1.8% decomposition even at the intense heat of 2000 ºC. As an acidic oxide, dry ice contributes its acidic properties by forming carbonic acid upon contact with water.

How is dry ice made?
The creation of dry ice begins as liquid carbon dioxide is sourced from a storage tank and meticulously introduced into the ice pressing chamber of a dry ice production machine. As it passes through the nozzle, a dramatic transformation occurs, generating a cloud of gas and snowflake-like dry ice solids.
Once a sufficient quantity of solid dry ice is gathered, the machine's hydraulic system springs to life, compressing these delicate snowflakes into robust dry ice cubes, which are then extruded from the die's end. At this moment, the machine's rotating blade activates, skillfully breaking the elongated dry ice column into manageable pieces.

These fragmented dry ice particles are crafted into the desired pellet length, ready for use in a range of applications.
There are three main principles of dry ice cleaning:
Energy Transfer: At the heart of dry ice cleaning lies the principle of energy transfer. Upon high-speed impact with a surface, dry ice channels kinetic energy into the task. The rapid heat exchange causes carbon dioxide to sublime, leading to a swift contraction and brittleness in the dirt, easing its removal.
Thus, the dirt is effortlessly washed away.
Low Temperature Cracking: Varying coefficients of thermal expansion in different materials generate significant temperature disparities, obliterating bonds. Dry ice pellets at -78.5 ºC strike the surface, freezing and embrittling the dirt, leading to its eventual crack and shedding.
The subsequent melting and fragmentation produce 'cracks' that compromise the dirt's mechanical integrity, encouraging its detachment.
Micro Explosion: As dry ice particles infiltrate dirt fractures, their sublimation occurs within mere milliseconds, volumetrically expanding by 600-800 times, effectively dislodging dirt from the object's surface.
