Discussion Overview

The discussion revolves around the effects of humidity on storing DVDs and electronic components in closed cardboard boxes, particularly during transitions between humid and dry climates. Participants explore how moisture behaves in various materials and the implications for storage conditions.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant questions whether moisture inside a closed cardboard box, containing DVDs and electronic components, evaporates when transitioning from a humid to a hot and dry climate.
  • Another participant introduces the concept of diffusion and notes that the time scales for moisture movement depend on the materials involved.
  • A further contribution discusses how water molecules move through different grades of plastic bags and highlights the role of paper and cardboard as reservoirs for water vapor, which may prevent condensation.
  • Concerns are raised about the brittleness of dry plastic bags and the importance of moisture in preserving plastic materials.
  • There is a mention of a participant's history of discussing humidity-related issues, suggesting a pattern in their contributions.

Areas of Agreement / Disagreement

The discussion contains multiple competing views regarding the behavior of moisture in different materials and the implications for storage, with no consensus reached on the specific effects of humidity changes.

Contextual Notes

Participants acknowledge the complexity of moisture dynamics in various materials, with some assumptions about material properties and environmental conditions remaining unresolved.

Substandard Post Quality -- Newbie reminded to use better sentence structure, punctuation and paragraphs.
If I have a dvd disk inside those plastic boxes suitable for dvd disks in black, if I have an electronic board inside a bag or papers inside any plastic bag and after that all of them inside a closed cardboard box when I closed the cardboard box or bag or dvdbox it was in rainy or humid weather or even dry but with some humidity but in rainy season the humidity entered the box, bag or dvdbox when that climate is changed from rainy and one gone to hot and dry (31-35C) is the moisture that is inside the cardboard box, inside the bags and inside the dvdbox evaporated or does this only happen if you heat them intensely? that is, does the change to a dry and hot climate dry or not these items of moisture deposited on them?

This is a diffusion question and the time scales depend upon the exact materials involved.

Sentences are a useful part of grammar.

Water molecules will move at different rates through plastic bags, depending on the grade of the plastic.

Dry plastic bags are brittle. Plastic is preserved by the presence of excess water, which is a plasticizer for PE.
Paper and cardboard act as a reservoir for water vapour, that prevents local condensation by virtue of the huge surface area of cellulose fibres.
That leads to a complex relationship.

(Note -- this turns out to be a well known and prolific sockpuppet who seems to have mental fixations on humidity and his DVD/CD collection. Accordingly this latest sockpuppet has been shown the door.)
