Calcium Chloride is sold either as a solid or in liquid solutions. Solid forms of Calcium Chloride are odourless, white to off-white pellets, mini-pellets or flakes, such as meadow Calcium Chloride, Anhydrous Calcium Chloride 94-97% or dew flake Calcium Chloride. solution products of Calcium Chloride, such as liquid Calcium Chloride solution, are odourless, colourless to pale yellow liquids with viscosities that vary with the concentration.

Cacl2, is a common salt. It behaves as a typical ionic halide, and is solid at room temperature. it has several common applications such as brine for refrigeration plants, ice and dust control on roads, and in concrete. It can be produced directly from limestone, but large amounts are also produced as a by-product of the Solvay process. because of its hygroscopic nature, it must be kept in tightly-sealed containers. it is used to turn kelp into a solid.

Because it is strongly hygroscopic, air or other gases may be channelled through a column of Calcium Chloride to remove moisture. in particular, it is usually used to pack drying tubes to exclude atmospheric moisture from a reaction set-up while allowing gases to escape. It cannot, however, be used to dry alkaline gases such as Ammonia because it will form addition products. It can also be added to liquids to remove suspended or dissolved water. The dissolving process is highly exothermic and rapidly produces temperatures of around 60 °C (140 °F).

In this capacity, it is known as a Drying Agent or Desiccant. it is converted to a brine as it absorbs the water or water vapor from the substance to be dried.

Component Information / Information on Non-Hazardous Components
The components of this product are not regulated as hazardous under 29 CFR and 49 CFR. However, the manufacturer recognizes the potential for respiratory tract irritation as a result of inhalation of this material as a respirable dust. See Sections 8, 11, 14, and 15 for further regulatory information.

SECTION 3: HAZARDS IDENTIFICATION

Emergency Overview: Sodium poly acrylate is a white, granular, odorless polymer that yields a gel-like material with the addition of water.

MOISTURE OR SWEATING PROTECTION IN CONTAINER LOADS

We introduce ourselves as manufacturers of Desiccant Silica Gel / Desiccants (Calcium Chloride base product) are REACH Compliant and DMF free which is used as moisture absorbent all over the world for protection of various products susceptible to moisture in export and also protects from container sweating / inhibits the formation of mold, mildew, rust and corrosion / prevents cartons and labels from moisture damage / environmentally safe and can be disposed of as normal waste. Particularly in export shipments the quality deteriorates due to moisture, as during sea voyage the humidity is almost 100%. main property of Desiccant Silica Gel / Desiccants (Calcium Chloride base product)is to absorb moisture prevent or coming inside the containers and thereby it controls humidity.


of Desiccant Silica Gel / Desiccants (Calcium Chloride base product)is a specially formulated desiccant product, non-toxic, harmless, odourless, PCP free chemical designed to lower the humidity inside shipping and storage containers.


Normally goods are packed inside carton boxes, drums, crates, wooden pallets, plastic bags etc. prior to loading into the container for shipment. Once in transit, the goods can be adversely affected by sudden changes in climatic conditions. often container rain occurs on the inner walls and ceilings of the container caused by temperature variation. Condensation may also be caused by a number of other external and internal factors like moisture content of pallets, container ventilation holes, crossing climatic zones during transit and the process of loading the containers in humid environments.


Quantity of Desiccants (Calcium Chloride base product) packets to be used:

For 20 feet container - 25 x 400 gm. Desiccant packets = 10 kg 
For 40 feet container - 50 x 400 gm. Desiccant packets = 20 kg


Desiccant packets adsorbs up to 150% or more at 100% R.H. and at 15°C for 90 days

There is no harm in using more quantities in fcl packing if cost permits.


OR


Quantity of Desiccant Silica Gel packets to be used:


For 20 feet container - 50 x 500 gm. Silica Gel packet = 25 kg

For 40 feet container - 100 x 500 gm. Silica Gel packet = 50 kg


Desiccant Silica Gel packets adsorbs minimum 25 to 30% at 100% R.H. and at 15°C for 90 days


There is no harm in using more quantities in fcl packing if cost permits.


PACKING INSTRUCTIONS:


1. First stuff your export items inside the container.  

2. We are supplying Desiccant in special packet of one side Tyvek and other side plastic made. you have to put the packets with Tyvek portion placed up and plastic portion down. we are printing "front side up" on Tyvek side to easier to use.

3. We are supplying Desiccant packet in sealed poly packets open our poly packets take out the Desiccant packet and put required quantity near the gate before closing it.

4. Please ensure that while packing Desiccant is given minimum exposure to the air otherwise it will absorb moisture from the air and its effectiveness will be much reduced.

MOISTURE DEVELOPMENT INSIDE THE CONTAINER IN TRANSIT

In 20 feet container has a volume of 33 cubic meter appx.

At 90% RH. and at 30 degree centigrade in one cubic meter of air contains 33 gram of moisture appx.

After stuffing, it is likely that 30% of the container has void spaces which is equivalent to 10 cubic meter ,then there is about 333 gram of water present inside the container.

Moist air is entering the container during sea transit from various points,now if it takes 30 days to reach the destination then total 9990 gram of water may occur inside the container during transit which is rough estimate.

For adsorbing 9.90 kg of water ,10 kg of Spacedry® Desiccant bags are to be used.

Note:

  • Desiccant bags adsorbs moisture to the extent of 150%.
  • 2.It does not include the water from other sources (such as wooden pallets and packaging material inside the container and also from cargo.)
  • 3.If there is any ventilation in the container kindly close the same by applying adhesive tape on it so that the outside moist air going inside the container could be minimized

Below figure show how much Desiccant packets to use :

 
Volumn inside container after stuffing Water in per cubic meter at 90% RH. & 30 c Total water developed during transit for 30 days Quantity of Desiccants required
10% 108.90 gm 3267 gm 3.5 kg
15% 163.35 gm 4900.50 gm 5 kg
20% 217.80 gm 6534 gm 6.5 kg
25% 272.25 gm 8167.50 gm 8 kg
30% 326.70 gm 9801 gm 10 kg
40% 435.60 gm 13068 gm 13 kg
50% 544.50 gm 16335 gm 16 kg

Important: Instances have been reported that after reaching the destination there was about 6" level of water inside the container when no safeguards were taken.

If the volume inside the stuffed container is less than 10% we would advise to use 10 kg of Desiccant packets. If you compare the cost factor it is very negligible.

HUMIDITY PROBLEMS

Whenever goods are moved from a hot climate to a cooler climate, condensation will occur because warm air holds more water than cold air. when the temperature inside the container/box is lowered the air will reach the dew point and the water will condense. This is when fungus, mould and mildew occurs, damaging the goods. Worse yet, if the water condenses on the surface of metal products corrosion occurs

#

CHAT SHOWING AIRS ABILITY TO HOLD WATER AT VARIOUS TEMPERATURES AND RELATIVE HUMIDITY.

If a container is loaded during high temperatures and the relative humidity is about 80%-90%, then the possibility of condensation occurring is substantial when the temperature is begins to drop. Desiccants helps keep the dew point temperature below the actual temperature, even when the actual temperature drops within the shipping container due to temperature fluctuation."Dew point temperature"is the temperature at which water vapor begins to condense onto a surface forming liquid water. The liquid that results inside a container is called "Container Rain". Container rain will occur if the surface temperature of an object is equal or lower than the dew point temperature. If the Relative Humidity is lowed with the absorbing properties of Spacedy , the dew point temperature is also lowered, stopping Container Rain.
