What are the characteristics and characteristics of Activated Carbon Desiccant?
Activated Carbon Desiccant is commonly used in a moisture-proof products, also known as container desiccant, dry bars, dry rods, etc., the main raw material is calcium chloride. Calcium chloride moisture absorption rate in the desiccant category is the highest product, its moisture absorption rate of about 300% of their own weight, is the ideal container container moisture products. Activated Carbon Desiccant can effectively keep the container dry, to prevent the transport or storage process due to temperature and other factors arising from the "container rain, container rain" and so on.
First, the characteristics of Activated Carbon Desiccant products
Container ocean transport or storage process, the ordinary day and night temperature difference between the sea, so that during the day locked in the container of water vapor-rich high-temperature air, at night due to temperature drop water vapor to reach supersaturation, the container will often experience the ocean weather and Strong day and night temperature changes, the temperature change will be 0 ℃ ~ 80 ℃, the temperature will be as high as 98%, which is condensation phenomenon. When the temperature is 30 ℃, the air content of water is 30.4g / m3. When the temperature dropped from 30 ℃ to 18 ℃, the water vapor content will drop to 15.4g / m3. The other water vapor condenses into water, if the 40-foot container is issued 1000g of condensate, which is commonly known as "container rain" on the packaging of the goods caused a very negative impact.
Dongxing Industrial Co., Ltd. of Dongguan Activated Carbon Desiccant is the main component of calcium chloride desiccant and montmorillonite, at 25 ℃, relative humidity of 80% of the conditions, the maximum capacity of adsorption of water can exceed 70%, arrived abroad similar Product performance. The pure smectite desiccant, at 25 ℃, relative humidity of 80% of the conditions, the adsorption capacity is generally not more than 30%. This composite desiccant greatly improves the dry and dehumidifying properties while maintaining the montmorillonite properties.
Second, the characteristics of Activated Carbon Desiccant
1, environmental protection:
There is no filler, pigments and adhesives for most of the acid, alkali substances do not work, after anti-static accumulation and discharge treatment completely burned, leaving only carbon dioxide and water vapor, environmental protection products for excellent ventilation, And the liquid and solid molecules can not pass; waterproof, anti-dust, non-toxic harmless, pure neutral; not mold under the same conditions (temperature 25 ℃, humidity 80%), moisture absorption is about 5 times the ordinary silica gel. Moisture content of more than 150 grams Compatibility with the traditional mineral desiccant (such as silica gel, etc.), the desiccant natural montmorillonite minerals for the moisture body, a special process from refining. The product is 100% biodegradable.
Third, the application of Activated Carbon Desiccant
In the container can be placed directly in different directions, the specific number according to the type of goods, packaging materials, transportation cycle, the weather changes (temperature, humidity changes), moisture standards, etc., generally 20 feet container (container) to follow the need to absorb 8-16 Kg of water vapor to be certain, if the adsorption capacity of 70% in line with the desiccant, you need to place 10-20 kg desiccant, 40-foot container desiccant dosage is doubled.
Fourth, the main purpose of Activated Carbon Desiccant
Activated Carbon Desiccant in addition to container transport in the container, but also can be used in container aviation, railways, road transport and cargo storage, but also directly used in large machinery, electronics, communications equipment, moisture-proof packaging.
