Factors Affecting Toughness of Enameled Wire
Adaugat pe 22/05/2020 08:01:21 de xiuweetime

Toughness testing of enameled wire is also a very important
work. What factors will affect the toughness of Enameled Wire? Let's learn about
it together.


The elongation of the paint film itself is very small, and it
has adhesive force when applied to the wire, which is caused by the mutual
diffusion of molecules between the paint and the metal. Enameled wire enamel is
a polar polymer with good compatibility with conductors, which is conducive to
molecular diffusion and good adhesion.


If the surface of the conductor is contaminated with nonpolar
substances or dirt, the adhesion of the paint film will be reduced, and the
flexibility of the polymer chain is related to the composition of its main
chain. The carbon atoms of the two single-chain combinations can freely rotate
around their central axes. Increasing the crosslinking degree of the polymer can
increase the rigidity of polymer, but reduce the flexibility. When the molecular
chains are crosslinked, they are united into a whole, which restricts the
movement of the molecular chain segments between the cross-linking points.
Excessive crosslinking makes the material lose flexibility and increase
brittleness.


For certain paint, the change of the elasticity of the paint
film is mainly due to the crosslinking of the lacquer-based resin. If the
enameled wire is not baked sufficiently, the lacquer-based resin does not reach
a certain crosslinking degree and does not form an appropriate body structure,
then the elasticity and adhesion of the paint film are poor. If baking is
excessive and crosslinking is too high, the elasticity will also decrease, and
the surface particles of the paint film will lead to stress concentration during
winding, which will also affect the elasticity of the paint film.
