What are Dry Ice Packs and Dry Ice Bricks?

الجليد الجاف هو ثاني أكسيد الكربون الصلب (co₂) that sublimates at an extremely low temperature of -78.5°C (-109.3° f). It is used to maintain frozen and chilled conditions for temperature-sensitive goods during transport. Dry ice packs and dry ice bricks, while both effective in cooling, serve different purposes depending on the shipping requirements.

حزم الثلج الجاف

Dry ice packs are flexible, lightweight sheets that are often used for small to medium-sized shipments. They are typically filled with small pellets of dry ice and encased in materials like plastic or foam. Dry ice packs are ideal for short-duration shipping and can be easily arranged in packaging to fit various sizes.

طوب الثلج الجاف

طوب الثلج الجاف, على الجانب الآخر, are large blocks of dry ice that offer a more concentrated cooling effect. These are ideal for longer shipments, providing extended cooling durations. The rigid form of dry ice bricks allows for more stable temperature control during longer journeys.

How Do Dry Ice Packs and Dry Ice Bricks Maintain Cold Temperatures During Shipping?

Dry ice achieves its cooling power through sublimation, where it transitions from solid to gas without becoming liquid. هذه العملية تمتص الحرارة, effectively lowering the surrounding temperature.

Sublimation Process and Cooling

• حزم الثلج الجاف: Sublimate at -78.5°C, providing moderate cooling for 24 ل 48 ساعات. Their flexibility allows them to be easily distributed throughout the shipping container, maintaining consistent cold temperatures for smaller shipments.

• طوب الثلج الجاف: Sublimate at the same temperature, but their larger mass and solid form cause them to release CO₂ gas at a slower rate, allowing them to maintain cold temperatures for longer, making them ideal for shipments lasting up to 72 ساعات أو أكثر.

أفضل الممارسات لاستخدام الجليد الجاف في الشحن

التغليف المناسب

• العزل: Use high-quality insulated boxes like Styrofoam or polyurethane foam to reduce heat transfer. Ensure the packaging allows for CO₂ gas to escape, as dry ice sublimates into gas.

• تنفيس: Dry ice must be packed in containers that allow the CO₂ gas to vent to avoid pressure buildup, which could lead to the rupture of packaging.

حساب الكمية المناسبة من الثلج الجاف

The quantity of dry ice required depends on factors such as the shipment’s duration, جودة العزل, ودرجة الحرارة المحيطة أثناء النقل. كقاعدة عامة, for a 24-hour shipment, 0.5 kg of dry ice per kg of the product should be used. لفترات أطول, increase the amount of dry ice by 1.5 times to account for sublimation rates.

وضع العلامات والتوثيق

عند الشحن مع الجليد الجاف, it’s crucial to comply with regulatory requirements:

• Proper labeling with “Dry Ice” or “Carbon Dioxide, صلب"

• UN1845 shipping number

• فصل 9 تسمية الخطر

• The net weight of dry ice in kilograms

These labeling requirements are essential for ensuring safe and compliant transport.

Safety and Regulatory Compliance for Dry Ice Shipping

يصنف الثلج الجاف على أنه مادة خطرة (فصل 9, UN1845) and requires adherence to specific shipping regulations. Compliance with IATA (الرابطة الدولية للنقل الجوي) ونقطة (وزارة النقل) guidelines is mandatory to ensure safe shipping.

Key Compliance Requirements:

1. التغليف: Dry ice must be transported in vented packaging, such as corrugated cardboard boxes with foam insulation.

2. التوثيق: Include a proper air waybill with the shipping details, including the weight of dry ice.

3. التعامل: Always wear insulated gloves and safety goggles when handling dry ice to prevent injury from frostbite or eye exposure.

الجليد الجاف مقابل. حزم هلام: أيهما أفضل لشحنتك?

Dry ice is often compared to gel packs, especially for shipments that need to be chilled but not frozen. لكن, dry ice has several advantages for specific needs:

الجليد الجاف

• Extremely Low Temperatures: Dry ice can keep frozen goods solid, unlike gel packs, which are not designed for subzero temperatures.

• مدة أطول: طوب الثلج الجاف, بخاصة, provide longer cooling durations than gel packs.

حزم هلام

• Safer and Easier to Handle: Gel packs are non-toxic, قابل لإعادة الاستخدام, and require no special handling. لكن, they cannot achieve the ultra-low temperatures necessary for frozen goods.

• Shorter Cooling Period: Gel packs are ideal for chilled items but not suitable for extended freezing.

Environmental Impact and Sustainability of Dry Ice Shipping

في 2025, sustainability is a key concern in the cold chain logistics industry. Dry ice offers some environmental advantages but also has its drawbacks.

Pros of Dry Ice:

• المستصلحة CO₂: Many suppliers produce dry ice from CO₂ captured during industrial processes, تقليل الانبعاثات.

• No Water Waste: يتصاعد الثلج الجاف مباشرة إلى الغاز, leaving no water residue and reducing waste.

التحديات:

• CO₂ Release: Although CO₂ is reclaimed, it is released into the atmosphere during sublimation.

• استخدام الطاقة: The production of dry ice requires energy, typically from non-renewable sources.

Sustainability trends include the use of biodegradable refrigerants, IoT-enabled temperature monitoring, and smart packaging solutions.
