Silica Gel in Guwahati

Water Chemicals India is a trusted Silica Gel supplier in Guwahati. The aim of using silica gel sachets is to minimize the risk of irreversible damage to items in transit or storage caused by condensing water vapour in Guwahati. By adsorbing water molecules, a silica gel sachet will reduce the Relative Humidity inside a package to levels at which condensation will not occur.

Three Main Moisture Sources to Consider in Guwahati:

• Air in the Package – Moisture from the air contained inside the package
• Packing Materials – Moisture from packing materials added inside the package (e.g., for cushioning purposes)
• Diffusion – Moisture that diffuses through the outer packaging during storage or transit

Factors Considered in British Standard 1133: Section 19:1968:

• A – Area of Moisture Barrier – A is the area of the moisture barrier (in square meters)
• R – Moisture Vapour Transmission Rate – R is the moisture vapour transmission rate of a barrier (in grams per square meter per 24 hours, measured at 90% RH and 38°C)
• V – Volume of Air – V is the volume of air inside the barrier (in cubic meters of the container)
• DF – Dumpage Factor – DF is the weight and type of packaging material inside the barrier; D is the weight of packing material in grams and F is a factor depending on the type of damage and its probable moisture content
• M – Time Protection Required – M is the length of time protection is required (in months)
• Climate Type – Temperate (average 25°C and 75% RH) or Tropical (average 38°C and 90% RH)

Typical R Values:

• 10 – Thin poly bag
• 3.4 – Heavy-duty poly bag (500 gauge)
• 2 – Heavy-duty poly bag (1000 gauge)
• 0.05 – Aluminum barrier foil

Formulae for Silica Gel Requirement:

• Temperate Climates: W = 11 × A × R × M + DF
• Tropical Climates: W = 40 × A × R × M + DF
• Hermetically Sealed Containers: W = 170 × V + DF

Where W is the weight of silica gel required (in grams):

It is difficult to get exact weights of silica gel required from the above formulae owing to the many variables that have to be considered, some of which are difficult to measure. The formulae can, however, be a useful guide to indicate the amount of silica gel required to give adequate protection. It is often prudent to choose the nearest standard size silica gel sachet above the value that W comes out at. For large values of W, a more effective solution than using a single large sachet is using a number of smaller sachets spread around the package. This will reduce the Relative Humidity at a faster rate.

Items Especially at Risk:

Condensation of water vapour from air will not occur, even when the relative humidity approaches 100%, providing the air temperature remains constant. So the risk of condensation (and therefore corrosion) arises mainly because of large drops in air temperature, where at the new lower temperature, the volume of water vapour is too much for the air to hold. Special attention needs to be paid in such situations.

Silica Gel Sachets for Home Use:

• Smaller Quantities Available – We have three sizes of sachets available in smaller quantities
• 50 × 10g – Self-indicating (blue to pink) silica gel sachets
• 25 × 25g – Self-indicating (blue to pink) silica gel sachets
• 10 × 100g – Self-indicating (blue to pink) silica gel sachets

Please remember also that there are applications to which silica gel is not really suited. These are mainly damp but large and unsealed spaces such as: bathrooms, basements, sheds, caravans, and cars (which are in regular use). Even quite large amounts of silica gel in areas such as these can quickly become exhausted and any improvement is often very short-term only.
