moisture migration

moisture movement

1. The process by which moisture moves through a porous medium, such as a wall construction, as a result of differences in vapor pressure.
2. The effects of such movement on the dimensions of a material such as concrete, mortar, cement paste, or rock.

Storing cheese in the form of blocks allows better refrigeration in the available space and it also reduces the moisture migration and in addition it helps to achieve the cheese standards, which is, in turn, anticipated to raise the demand for the block former over the forecast period.
"The fundamental problem was that building scientists (who understand moisture migration) and building owners, architects, and product manufacturers (who care mostly about outward appearance) didn't collaborate throughout the construction process," explained LBFG President George DuBose.
If there is no vent in the vicinity, check the band joists and, if they are not fully insulated, please do so by placing R-19 fiberglass or Roxul insulation tightly against the band joists throughout the crawl space and staple a plastic vapor retarder to the floor sheathing, the sides of the joists and the mud sill in each space to protect the insulation from moisture migration.
Accordingly, this kind of regional climatic condition is apt to intensify moisture migration and frost heave.
Weibull distribution can be used to calculate the effective moisture diffusivity, regardless of the characteristics of moisture migration during drying process.
Additionally, the surface and the interior water showed different migration behaviors during storage, and moisture migration played a decisive role in the hardening of noodles [14].
The rate of moisture migration from the inner surface to the outer surface decreases at the final stage of drying and hence leads to lower drying rates (Rajkumar, Kailappan, Viswanathan, & Raghavan, 2007).
And the moisture migration may affect the change of soil pores, such as the size of pores and the pore water press, which may cause frost heave and the damage to the infrastructure [1, 2], while for the salinized soil in cold region the soluble salt which is dissolved in the water would be transported during the water migration in the process of freezing, which can cause the secondary salinization [3, 4].
During the hot pressing of wood-based composites, heat transfer from an external heat source increases the temperature of the mat, and results in water evaporation, a gas pressure change, and moisture migration. Moisture migration also affects heat transfer.
Soil frost heave and thaw collapse are complex processes, involving moisture migration, change of temperature field and effect of stress field.

In many instances, the medical device manufacturer may also need to specify additional protection from UV light, as well as oxygen and moisture migration, all of which have a negative impact on shelf life and efficacy.
