Micathermic heater. A micathermic heater is a type of space heater in which the heating element is covered in thin sheets of mica. Micathermic heaters produce both convection heat and radiant heat, [1] and are usually thinner than other types of heaters. [2]
Mica is used in plastic automobiles fascia and fenders as a reinforcing material, providing improved mechanical properties and increased dimensional stability, stiffness, and strength. Mica-reinforced plastics also have high-heat dimensional stability, reduced warpage, and the best surface properties of any filled plastic composite.
In a suspended design, a resistance heater is attached at two or more points to normally either a ceramic or mica insulator. Suspended resistance heaters can transfer heat via convection and radiation, but not conduction as they are surrounded by air. In an embedded heating element, the resistance heater is encased in the insulator.
A ceramic heater as a consumer product is a space heater that generates heat using a heating element of ceramic with a positive temperature coefficient (PTC). [1] [2] [failed verification] Ceramic heaters are usually portable and typically used for heating a room or small office, and are of similar utility to metal-element fan heaters.
The heating element in most dryers is a bare, coiled nichrome wire that is wrapped around mica insulators. Nichrome is used due to its high resistivity, and low tendency to corrode when heated. [11] A survey of stores in 2007 showed that most hair dryers had ceramic heating elements (like ceramic heaters) because of their "instant heat ...
Space heaters can and do cause fires, making it important to be mindful about how you use them. However, experts say it's possible to use electric space heaters safely. If your model is new, is in ...
