Biscuit Firing Tube Aluminum Oxide Ceramic In The Electroplating Industry
1.Introduction
AluminaCeramic diaphragm electrolysis 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.

Our Alumina ceramic biscuit firing tube is made from high purity alumina ceramic powder, and it has very good performance of acid fastness and fastness to alkali. We sinter ceramic firing tube at 1500 ℃, so our firing cost is high. It can make high strength ceramic diaphragm. The key technology of this product is that the porosity of the product is high and the distribution of pores is uniform, the pore diameter is moderate, the resistance of electrolysis is very small, and the uniform current distribution can be obtained, which is the product performance.
