Why Use Calcium Chloride Desiccant?

Calcium chloride absorbs moisture from the air effectively. It can attract several times its own weight in water, dissolving into a liquid brine if the air is humid enough and the temperature is high enough. The liquid brine is either trapped inside a collector or mixed with a modified starch and thereby formed as a gel inside its packaging.

Absorption capacity

Calcium chloride desiccant absorbs more moisture when the relative humidity (RH) of the surrounding air is higher. And its absorption increases exponentially as RH rises, which is a remarkable result compared to other desiccants like silica gel and clay.

The sustainable option

Other desiccants may include toxic substances. For example, silica gel with indicators, can include the toxic substance cobalt. Whereas calcium chloride is a natural product with no negative affect on the environment. By choosing the most efficient desiccants, huge savings can be made on plastic, transport and the CO2 footprint as a result.

Precautions for Use

This is important: calcium chloride is exceptionally corrosive to metal. Overall, the salt eats away at the metal and rusts any metal inside the safe. Therefore, you should never dehumidify your safe, car, or other places where metals are stored with calcium chloride dehumidifiers or crystals.

For the same reason, it’s a good idea to avoid calcium chloride for boats and RVs. While many marine surfaces are resistant to corrosion, extended exposure to this chemical can present a problem.

Considering Whether to Use Calcium Chloride Desiccant

Application – Inside a Package Versus Inside a Shipping Container

Calcium chloride needs high levels of sustained moisture to perform, which you do not find inside packages. Inside packages the humidity is less extreme and is not sustained, and under these conditions calcium chloride absorbs poorly.

The opposite is true inside shipping containers where the humidity is extreme and sustained. Calcium chloride performs optimally in these conditions and has the capacity to remove the necessary amount of moisture to prevent container rain.

Desiccant Characteristics

Calcium chloride turns into a highly corrosive liquid gel which presents a risk of leakage. If it leaks it can cause irreparable damage to your products. In fact, we do not recommend using calcium chloride with electronics or metal parts due to its corrosive nature.

Sustainability

Silica Gel Desiccant For Preserving Flowers

To prevent leakage, calcium chloride desiccants require two layers of packaging; an inner plastic pouch with an outer non-woven layer. As a result, they tend to use 4X more packaging materials than other desiccants.

Desiccant Storage and Warehousing Precautions

Keep the desiccant in a cool dry place, keep note of the fire, theft, pest, moisture and damage.

Under normal circumstances (non-constant temperature and humidity), we should pay more attention to moisture-proof. Avoid excessive moisture from the outside. Make sure the floor (ground) is dry and clean. Otherwise, the cartons are easy to get mildewed.

When stacking the desiccant cartons, stack them into a neat, stable, straight line. Leave enough space, stay away from the walls, pillars. Distance should be at least larger than 0.3~0.5 meters.

Certificate

We had passed the ISO9001:2015, ISO14001:2015, BSCI, GMP and Walmart audits. Our products comply with RoHS certification and other certificates.

Common Problems

Q: Is calcium chloride desiccant safe?

A: Over time, long-term exposure to calcium chloride and its dust can cause lung damage, as well as other respiratory issues in the nose and throat. It can also cause skin irritation and contaminate clothing.

Q: Is calcium chloride desiccant better than silica gel?

A: Our first conclusion is that calcium chloride performs better than silica gel in tougher conditions, especially when the relative humidity is high. These are conditions where moisture damages such as mould, bad smell, peeled labels and collapsed packaging are more likely.

Q: Is calcium chloride the same as silica?

A: Calcium chloride is over ten times more powerful and hygroscopic than silica gel, however - unlike silica gel - it is not an inert product and is classified as dangerous and irritating. By absorbing moisture, it creates a leachate which is in effect a highly irritating and corrosive special chemical waste.

Q: What is calcium chloride used for in packaging?

A: Anything that qualifies as a desiccant means it's used as a drying agent. Using calcium chloride in foods helps to absorb any moisture that would create an environment where bacteria would thrive. With such a widely-applicable benefit as a drying agent, calcium chloride is used in a number of applications.

Q: Is desiccant harmful to health?

A: Silica gel is non-toxic but it is a choking hazard for young children. However, in some rare instances, manufacturers coat silica gel in cobalt chloride, a toxic compound. Eating cobalt chloride-coated silica gel will likely cause nausea and vomiting.

Q: Should I avoid calcium chloride?

A: Ingesting calcium chloride is a serious safety and health risk. It can cause burns to the mouth, throat, and stomach. This can lead to vomiting, extreme thirst, stomach pain, and low blood pressure. Sometimes, manipulation of this salt can create dust particles.

Q: Is calcium chloride a good moisture absorber?

A: Calcium chloride is highly effective, and one of the most hygroscopic materials, when it comes to absorbing moisture from the surrounding air. Calcium chloride is an inorganic compound – a salt with the chemical formula CaCl2.

Q: Is calcium chloride safe in dehumidifiers?

A: Traditional dehumidifiers have used calcium chloride to collect moisture from the air, but this chemical is a dangerous substance to have within your home. It can cause damage to property and people due to its properties. Calcium chloride is a chemical used in some do-it-yourself dehumidifiers.

Q: Why is calcium chloride used for drying?

A: Calcium chloride is strongly hygroscopic (absorbs water from its surroundings), so it removes moisture from the air, making it dryer. This results in water in the substance to be dried to evaporate into the drier air, and this cycle repeats until the system reaches an equilibrium.

Q: Is it safe to touch desiccant?

A: A quick note about that safety warning you see all the time: Clear silica gel pellets are nontoxic and fairly safe to handle.

Q: How much moisture can calcium chloride absorb?

A: Calcium chloride can absorb up to 300% of its own weight in moisture, compared to 30-40% for clay. Surely the ability to absorb 10X more moisture makes calcium chloride a far superior desiccant? This is not necessarily the case.

Q: Why should contact with moisture be avoided for calcium chloride?

A: Calcium chloride will attract enough water so that it dissolves. Thus it would create a highly corrosive salt solution which could cause problems.

Q: What is the lifespan of a desiccant?

A: We recommend that a desiccant be replaced once every three years for open-cycle systems and once every two years for closed-cycle systems. A desiccant may degrade more quickly depending on the environment where it is used. Dew point temperatures offer a good indication for when to replace your desiccant.

Q: Is calcium chloride environmentally friendly?

A: Calcium chloride is a salt with a low environmental impact. It is also highly efficient at absorbing water from the surrounding air.

Q: Is calcium chloride safe as a dehumidifier?

A: Safety Precautions: While calcium chloride is generally safe to use, it is important to handle it with care. Avoid direct contact with skin or eyes and keep it out of reach of children and pets.

Q: What is calcium chloride as a desiccant used for?

A: Calcium chloride desiccants work well over a temperature range from freezing point up to 80 °C or more. Calcium chloride is the active compound in all Absortech products. Calcium chloride is often used for de-icing or dust control on gravel roads, in food or as the absorbing agent in desiccants.

Q: Is desiccant safe to breathe?

A: Inhalation of silica gel is another risk; breathing-in may cause lung irritation, coughing and dyspnoea (short of breath). The small bags can cause choking and the packet may lacerate and release the contents into the mouth, throat, gullet or lungs.

Q: Is anhydrous calcium chloride often used as a desiccant?

A: In the presence of excess of CaCl2, the amount of the water taken up is governed by K, = 6.4 x 105 for the following reaction at room temperature, CaCl2(8) + 6H2O(g) = CaCl2. 6H2O(8).

Q: Is calcium chloride safe to use as dehumidifier?

Q: Is calcium chloride desiccant reusable?

A: Anhydrous calcium chloride is a common one that can also be reactivated and then reused. The water absorbed by the desiccant can be removed by heating it to a high temperature until the water evaporates, leaving just calcium chloride behind.
