Que sont les feuilles de glace sèche et comment fonctionnent-elles ??

Les feuilles de glace carbonique sont flexibles, des compresses froides réutilisables qui utilisent un polymère superabsorbant pour absorber l'eau et atteindre des températures de congélation extrêmement basses. Ils sont conçus pour conserver les denrées périssables, fournitures médicales, et autres articles sensibles à la température froids pendant de longues périodes, much longer than regular gel packs.

Lorsqu'il est activé, these sheets undergo a process where a polymer inside absorbs water and forms a hydrogel, freezing to temperatures as low as -21°C (-40°F), far below traditional ice or gel pack freezing capabilities. This feature makes them ideal for cold chain logistics.

Principaux avantages des feuilles de glace carbonique:

• Flexibilité: These sheets are more adaptable than solid dry ice or gel packs, allowing them to fit into tight spaces and wrap around products for more efficient cooling.

• Durée de refroidissement plus longue: Une fois activé, dry ice sheets last up to 7 times longer than standard ice, making them highly effective for longer transportation times.

• Réutilisable et rentable: Dry ice sheets can be reused multiple times, reducing the cost and environmental impact of single-use ice packs.

Step-by-Step Guide on How to Activate Dry Ice Pack Sheets

To ensure your dry ice pack sheets perform optimally, follow this simple guide for activation:

Étape 1: Gather the Necessary Materials

Before starting the activation process, make sure you have the following:

• Feuilles de glace carbonique

• Chaud (pas bouillant) eau

• A shallow container or sink

• A towel for drying

Étape 2: Immerse the Sheets in Warm Water

• Submerge the Sheets: Place the dry ice pack sheets into a shallow container or sink filled with warm water. Ensure the sheets are fully submerged.

• Weigh Down the Sheets: Place an object on top to keep the sheets fully immersed, ensuring even hydration.

Étape 3: Hydrate the Sheets

• Wait for Absorption: Let the sheets soak in the warm water for approximately 10–15 minutes. Pendant ce temps, the polymer inside the sheets will absorb the water and expand, preparing them for freezing.

• Massage the Sheets: Gently massage the sheets to help air bubbles escape and ensure even hydration.

• Check the Thickness: The sheets will become thicker and firmer once properly hydrated. Ensure that they are not over-hydrated, as this could affect their performance.

Étape 4: Dry the Sheets

• Remove Excess Water: Once the hydration process is complete, remove the sheets from the water.

• Pat Dry: Use a towel to remove any excess moisture. This step is essential to prevent ice buildup on the exterior during freezing.

Étape 5: Freeze the Sheets

• Place in Freezer: Lay the hydrated sheets flat in your freezer, ensuring they do not overlap for even freezing.

• Optimal Freezing Time: Freeze the sheets for at least 24 hours for maximum cold storage capacity.

Factors That Affect the Performance of Activated Dry Ice Pack Sheets

Understanding the factors that affect the performance of dry ice pack sheets will help you extend their cooling duration and improve overall efficiency during transport:

Qualité de l'isolation

The quality of insulation in your cooler or storage container significantly impacts the effectiveness of dry ice pack sheets. High-quality insulation reduces heat transfer and slows down sublimation, keeping your dry ice colder for longer.

Température externe

External temperature plays a crucial role in the longevity of dry ice. Higher ambient temperatures increase sublimation rates, meaning dry ice will sublimate faster. In hot conditions, using more dry ice or enhancing your container’s insulation can help mitigate this effect.

Quantité de glace sèche

Using a larger quantity of dry ice will prolong the cooling duration. When shipping goods over longer distances, calculating the right amount of dry ice is crucial to ensure consistent temperatures.

Cooler Opening Frequency

Every time a cooler is opened, L'air chaud entre, accelerating the sublimation process of dry ice. Limiting access to the cooler will help maintain lower temperatures for longer periods.

How Long Do Activated Dry Ice Pack Sheets Last?

The duration that dry ice pack sheets remain effective depends on various factors such as insulation, température extérieure, and how much dry ice is used. Typiquement, activated dry ice pack sheets can last anywhere from 18 à 48 heures:

Meilleures pratiques d'utilisation de la glace carbonique dans la logistique de la chaîne du froid

To get the most out of your dry ice pack sheets, follow these best practices in cold chain logistics:

• Properly Seal the Cooler: Use tight-fitting lids or seals to minimize the entry of warm air, which will speed up the sublimation of dry ice.

• Place Dry Ice on Top: L'air froid coule, so placing dry ice on top of items ensures optimal temperature maintenance.

• Regular Temperature Monitoring: Use temperature monitoring devices inside the cooler to ensure the contents stay within the required temperature range.

2025 Tendances de l'utilisation de la glace sèche pour la logistique de la chaîne du froid

Dans 2025, the cold chain logistics industry continues to evolve, and so does the technology around dry ice. Les principales tendances comprennent:

• Alternatives écologiques: The shift towards sustainable packaging and cooling options, such as biodegradable alternatives, s'accélère.

• Technologies d'expédition intelligentes: Real-time temperature tracking and data logging are improving the management of dry ice and the cold chain process.

• Improved Insulation Technologies: Advancements in insulation are helping extend the effectiveness of dry ice packs, ensuring more reliable and efficient transportation of sensitive goods.

Common Questions About Dry Ice Pack Sheets

How Long Does It Take for Dry Ice Pack Sheets to Activate?

The activation process typically takes 10–15 minutes, during which the sheets absorb water and begin to expand.

Can I Use Dry Ice Pack Sheets for Long-Term Storage?

Dry ice pack sheets are ideal for short-term use (jusqu'à 48 heures). Pour un stockage à long terme, additional cooling methods may be required.

Are Dry Ice Pack Sheets Reusable?

Oui, dry ice pack sheets can be reused multiple times. Après chaque utilisation, they need to be properly rehydrated and frozen.
