The maximum operation (service) temperature of white mica is up to 600 DEG C. It is mainly used in making the major insulation material of large power generating equipment and high-voltage motor, is also applied to almost all of modern industry, including the electrical apparatus insulation of national defence and Aeronautics and Astronautics leading-edge field.
The electrical property of phlogopite is lower than white mica, but heat resistance is higher than white mica, and light color phlogopite is heated to more than 1000 DEG C and thermal expansion just occurs, therefore can be used below at 1000 DEG C, such as the fire safety electric wire etc. for heatproof less than 800 DEG C.
The similar phlogopite of synthetic mica chemical constitution, maximum operation (service) temperature is up to 1100 DEG C, as temperature fire safety electric wire etc. below 1000 DEG C.
Three of the above Muscovitum can be processed into high-temperature insulation material and other industrial materials such as mica sheet, mica powder, mica paper, mica tape, micarex.
The manufacture of domestic mica paper is with the mica flake of white mica or phlogopite or synthetic mica for raw material, on cylinder mould machine, calcinated type mica paper or non-calcinated type mica paper paper roll is manufactured paper with pulp into slower speed, then through the reel mica paper cut or flat board mica paper with chemical pulping or hydraulic slurrying.

In power industry, large and medium-sized high-voltage generator, motor can produce substantial amounts of heat in running, if derived not in time, its work efficiency will be directly affected, shorten the life-span, reduce its reliability, therefore motor heat transfer has become modern electrical machine technology urgent problem, is also the study hotspot of countries in the world insulating material.
It is known that the major insulation of motor is by completing by vacuum pressure mass-impregnation (VPI) technique by hot moulding curing process or to after the wrapped low resin mica tape of motor coil after the wrapped resin-rich mica tape of motor coil. Wherein, mica tape is the material of most critical, generally it is to be made up of mica paper (heat conductivity 0.47��0.51W/m K), glass cloth (heat conductivity 0.8��1.2W/m K) and adhesive (such as epoxy adhesive, heat conductivity 0.17��0.22W/m K). Saying on a macro scale, motor is made up of metal material and insulant exactly. For insulant, owing to not having the motion of electron stream, their heat conductivity differs 500��1000 times than metal material. Therefore, the heat conductivility improving insulant is to improve the important channel of heat-conductive characteristic during motor runs.
Owing to most of insulating polymeric materials are substantially thermal insulation, its heat conductivity is typically in 0.15��0.25W/m K, if epoxy glue is 0.2W/m K, silica gel 0.21W/m K, paulownia horse glue 0.18W/m K, catechol glutol 0.209W/m K, politef 0.25W/m K ... generally will not remove to improve the heat conductivility of insulant with macromolecular material.
Correlational study shows: from 0.25W/m K, insulant heat conductivity is brought up to 0.4W/m K, and output power of motor will promote nearly 10%; For the air cooled generator of same size, in same temperature rise situation, the highest lifting of its capacity one times can be made according to High-heat-conductiviinsulation insulation material.
How a kind of heat conduction mica paper is provided, is the focus of current this area research.
