FAQ

"Chemical residue" refers to traces, remnants, or residual substances of chemicals left behind in a process, product, or environment. These chemical residues can originate from various sources such as chemicals, medications, pesticides, cosmetics, food processing, industrial production, environmental pollution, among others. Chemical residues are typically substances that have not fully decomposed, dissolved, or been removed.

"Homogeneity" typically refers to a concept in statistics and data analysis, also known as "uniformity" or "homogeneity testing." It is used to assess the variation or dispersion of observed values within a dataset to determine if they are evenly distributed across the entire data range.

For dry ice, our minimum order quantity is 1 kilogram (for self-pickup, additional charges apply for delivery). For other products, which are primarily machines, detailed product descriptions can be found on our website under the "Product Zone."

Direct Pressing of Dry Ice: This is a process for manufacturing dry ice pellets (blocks) where a compressor is used to inject liquid carbon dioxide (CO2) into a molding die. The CO2 is then cooled and pressurized to form uniform and regular dry ice pellets (blocks). This process is typically employed for producing high-quality dry ice suitable for various applications, such as food transportation, refrigeration, and special effects. Specialized equipment is often required for different sizes and shapes of dry ice

Yes! Customers are required to provide their own storage containers. The freezing point of dry ice is extremely low, at -78.5 degrees Celsius (-109.3 ℉), and the sublimation loss rate is approximately 2-10% per day, depending on the quality of the storage container and the amount of dry ice stored. We also offer dry ice storage boxes (Thermal Insulated Boxes), including models BB030, BB060, BB100, and BB250, capable of holding 30kg, 60kg, 100kg, and 250kg of dry ice, respectively, and equipped with wheels for easy mobility. For more detailed product information, please refer to our "Product Section" on the website.

Dry ice is widely applicable in various scenarios and uses due to its unique properties, such as extremely low temperature, lack of chemical residues, and non-conductivity. The following provides a brief overview of occasions suitable for the application of dry ice:

The following diagram outlines precautions for the use of dry ice. Please take a look.

Spraying Method: Dry ice particles, when sprayed, rapidly cool the surface of contaminants, causing them to contract and become brittle. A compressive stress wave is generated between the coating and the substrate, and the energy between them is sufficient to overcome the bond strength, resulting in the separation of the coating from the inside out. For coatings with higher toughness or viscosity, such as oil, wax, or butter, the cleaning action of dry ice blasting is similar to the scouring action of highpressure water, removing the grease.

Dry ice cleaning utilizes the unique properties of dry ice particles, combining the concepts of thermal shock effect and online cleaning to achieve an efficient, environmentally friendly, and controllable cleaning process. The principles of these two cleaning methods are briefly described below.
