Transcript

  • 1. THERMAL INSULATION MATERIALS 12/12/2010 aravinprince@gmail.com Aravin Prince Periyasamy
  • 2. INTRODUCTION 12/12/2010 Military forces of many nations need to survive and fight in the most extreme aravinprince@gmail.com conditions known on earth. The cold/wet regions tend to cause the most severe problems, as it is necessary to provide and maintain dry thermal insulation materials.
  • 3. THERMAL INSULATING MATERIAL 12/12/2010• The cold/dry areas, including the arctic, antarctic, and mountainous regions require the carriage and use of clothing, sleeping bags, and other personal equipment which possess high levels of thermal insulation.• Military forces are prone to sacrificing thermal comfort for light weight and low bulk items.
  • 4. THERMAL INSULATION (PROTECTION FROM COLD): NEW DEVELOPMENTS: 12/12/2010 One new advancement in fiber technology involves the invention of a unique, patented thermal insulation of fine bonded polyester called aravinprince@gmail.com Primaloft®, manufactured by Albany International. It is used for insulating such things as sleeping bags and snow skiing clothes because it is light weight, durable and maintains its insulating properties when wet.
  • 5. THERMALLY SENSITIVE MATERIALS 12/12/2010 An ideal clothing fabric, in terms of thermal comfort, should have the following attributes: aravinprince@gmail.com High thermal resistance for protection from the cold, Low water vapor resistance for efficient heat transfer under a mild thermal stress conditions and; Rapid liquid transport characteristics for transferring heat efficiently and eliminating unpleasant tactile sensations due to perspiration under high thermal stress conditions.
  • 6. THERMAL STORAGE AND THERMAL INSULATING MATERIALS: 12/12/2010 aravinprince@gmail.com Zirconium magnesium oxide or iron oxide can be used as particulate filters in the molten polymer for producing heat generating Polyester, Polyamide, Polyethylene, Polypropylene and other functional fibers.
  • 7. EFFECT OF MOISTURE ON INSULATION 12/12/2010 Any fibrous, porous insulation material is adversely affected by the presence of moisture, whether this is perspiration or rain. aravinprince@gmail.com Replacing air of low thermal conductivity by water of high conductivity is the primary cause. Moreover, fibrous materials, particularly pile fabrics or quilted battings, have a high affinity for wicking and entrapping large amounts of moisture.
