Electrophoresis coating and coating method have been used in
industrial applications since the 1960s, and the use of
electrophoresis coating can be used in the whole closed circulation
system, and the utilization rate of coating can be up to 95%.
Electrophoresis coating is a membrane of water-soluble or
water-dispersible ionic polymers, which can be used as an anode or
as a cathode.
Electrophoresis coating can be divided into anodic electrophoresis
paint and cathodic electrophoretic coating according to the coated
workpiece electrode. The ions in the water can be divided into
anionic electrophoresis coatings and cationic electrophoretic
coatings. The cathodic electrophoretic coating can be divided into
single group of electrophoresis coatings and dual-component
electrophoretic coatings according to the water dispersion. Film
thickness can be divided into film type, medium thickness film and
thick film cathodic electrophoretic coating.
Principle 1, electrophoresis is one of the most effective methods
for coating metal workpieces. Electrophoretic painting is to have
been painted on the conductivity of the material in the full of
water to dilute the concentration of low electrophoretic coating as
anode or cathode in the tank, the other set in the tank and its
corresponding cathode (or anode), in the indirect communication
between dc after a period of time, in the coated surface
sedimentary out even close, not dissolved by water coating method
of a kind of special coating.
2. The electrophoretic coating process is accompanied by four
chemical physical changes, namely electrolysis, electrophoresis,
electrodeposition and electroosmosis.
(1) in the colloidal solution, scattered charged colloid ions in
the medium, under the effect of dc field, the move towards
electrode with heterogeneous charge, because of the gel ion
resistance by dispersing medium, in the process of movement
relative to the true solution ion migration resistance in an
electric field is much larger, movement speed is slow, like bathing
in the dispersion medium, is called electrophoresis. The speed of
colloidal electrophoresis depends on the double layer structure of
the electric field strength and the dispersion of water soluble
resin.
(2) electrolysis: when the direct current field is applied to the
electrolyte aqueous solution, the water will be electrolytic in the
electric field, and the oxygen will be precipitated out in the
anode area and the hydrogen will be precipitated out of the
cathode. Anodic reaction: OH ˉ 2 - write O2 + 2 h + 4 e cathodic
reaction: 1/2 h2 + H2O + e - write OH, electrophoresis, the higher
the content of impurity ions in the body, is the greater the
conductivity system, that is, the more the electrolysis of water is
intense, such as a large number of gas, to escape the electrode
resin when the deposit will be mixed pores, lead to coating pinhole
and rough. Therefore, in the electrophoretic coating process should
try to prevent impurity ions into electrophoresis fluid to ensure
the quality of coating.
(3) Electrodeposition in the electrophoretic painting, electrically
charged particles (resin and yan, material) under the effect of
electric field to reach the opposite charge electrodes, be H (anode
electrophoresis) OH (cathode electrophoresis) neutralization,
become insoluble in water film, this film is very stable, dense and
uniform. This process is called electrodeposition. As in anode
electrophoresis, when the negatively charged water soluble resin
particles under the effect of dc field arrived at anode) (the
coated workpiece, the electrodeposition reactions occur, the first
is OH discharge: OH ˉ 2 - write O2 + 2 h + 4 eOH + H = 2 H2O to
anode area around H accumulation as a result of the reaction, the
local lower PH, the excessive H in RCOO resin anion reaction,
namely the resin precipitation and deposition in the anode) (the
coated workpiece surface: RCOO + H - left ROOOH down.
(4) electroosmosis: this is a phenomenon that the dispersing medium
moves in the opposite direction to the electrophoresis particle.
Electroosmosis effect in the electrophoretic coating process is due
to the adsorption on anodic coatings of hydration cation, action to
move toward the negative electrode by electric field of the seepage
force, thus through the deposition coating, the coating deposition
significantly reduce the water content, which is about 5-15%, can
be directly baking, coating with dense structure level off is
smooth.
