Porous Alumina Ceramic pots in Chrome Electroplating
Product specifications:
1, 400mm× 500mm × 80mm (upper mouth 390mm ~ 400mm height 485mm ~
500mm width 80mm)
2, 160mm × 60mm × 520mm (flange 180mm× 80mm × 15mm,body 160mm ×
60mm× 515mm)
3, diameter 210mm ~ 215mm, height 650mm or 560mm or 800mm
Note: 1) In order to ensure the electrolysis effect and strength of
the product, the wall thickness of the product is designed to be
about 5-7mm thick.
Ceramic pots in the electroplating industry are mainly used in the
following two aspects:Using the principle of electrolytic
reductionoxidation reduction of thick liquid trivalent chromium.
ABS plastic plating pretreatment of coarse liquid, roughing plating
quality directly affects the quality of plastic parts. In rough of
process in the rough of liquid in the of six price chrome acid and
products produced corrosion reaction generated three price chrome
and organic, in rough of process in the, six price chrome will into
three price chrome, and with three price chrome of content
increased, will led to rough of liquid oxidation capacity weakened,
and ABS generated hydrophilic polar group of speed will sharply
declined, led to rough of effect declined, due to rough of bad,
plastic artifacts and plating layer of combines force also will
obviously declined. Trivalent chromium if the concentration rises
above 30 grams per liter, will seriously affect the up scaling
quality resulted in coarse liquid scrap. Roughing solution waste
contains large amounts of chromic anhydride and sulfuric acid, it
will be discarded, not only wastes a lot of resources, but will
seriously pollute the environment. Abroad (particularly in the
automobile industry) using ceramic membrane electrolysis process
reduces the trivalent chromium, regeneration of the roughing
solution in order to achieve energy conservation and environmental
protection.
Used in decorative chromium and hard chromiumplating to lift
impurities. In the production of decorative chromium and hard
chromium, due to workpiece cleaning dirtyreasons, making bath
cationic impurities in gradually increasing, impurities will result
in too much chrome plating color andperformance degradation even
scrapped the plating, electrolytic treatment of plating liquid and
power consumption for a longtime. Ceramic diaphragm electrolytic
plating solutions can effectively remove impurities in the
electrolyte captions, thus improving plating quality of products,
extending the life of plating.
