The Performance Evaluating Indexes of enamelled wire insulated paint be it is comprehensive, be broadly divided into ruler in IEC standard and national standard
A few major class index requests such as very little, hot property, mechanical performance, electrical property, chemical property influence each other between these performances, mutually
It restrains.For example, the heat resistance for improving paint film would generally be along with the decline of mechanical performance to a certain extent.Polyester-imide
(PEI) wire enamel is the heat resistance insulated paint for adapting to the requirement of motor high-fire resistance and developing, and is painted with polyamidoimide (PAI)
200 grades of composite enameled wires of envelope curve finishing coat cooperation production are widely used, and the ratio in enameled wire constantly rises.?
While heat resistance is improved significantly, its mechanical performance such as paint film adhesion and flexibility compared with polyester wire enamel
Deng but there is considerable degree of reduction.Especially in aluminium enamel-covered wire, big specification enamelling cuprum round line, flat wire and the product for adding inorganic matter
Under kind such as Inverter fed motor enameled wire application, adhesive force and paint film flexibility of the polyesterimide wire enamel on conductor become
Weak link, or even it is unable to satisfy standard requirements in many cases.
In general, solving the problems, such as this, there are two approach, one is passing through the modified paint film for improving polyesterimide wire enamel
Flexibility and adhesive force, but it is also necessarily accompanied with the decline of heat resistance to a certain extent simultaneously.Another solution is
Using multi-layer compound structure, in conductor together with polyesterimide wire enamel inter-coat high adhesion priming paint, to improve paint
Envelope curve overall mechanical properties.
