What is the insulation material in the hair dryer?
Aerospace industry on the use of insulation materials, the weight and volume requirements are more demanding, often also requires it both sound insulation, vibration, corrosion and other properties.
The former uses the pores contained in the material itself to insulate because the air or inert gas in the voids has a low thermal conductivity, such as foams, fibrous materials, etc .; the heat-reflective material has a high reflection coefficient that reflects heat Gold, silver, nickel, aluminum foil or metallized polyester, polyimide film and the like. Vacuum insulation material is the use of internal vacuum material to achieve the barrier convection to heat insulation
The heaters in the hair dryer are generally made of PP or ABS. Insulation material is divided into porous materials, heat reflective materials and vacuum materials three categories
The head of the missile with the early insulation material is phenolic foam, with good temperature resistance of polyurethane foam applications, in turn a single insulation material for the development of sandwich structure.
Various aircraft on the need for insulation materials are not the same. Aircraft cockpit and cockpit commonly used foam, ultra-fine glass wool, high silica cotton, vacuum insulation board to heat
