One. Features 1. Environmentally friendly products, hexavalent chromium, waste water treatment is simple. 2. Color uniformity, appearance, has good coverage and throwing power. 3. The bath does not contain organic solvents, sulfate and chloride tolerance is good. 4. Power outages will not have adverse consequences plating, deposition rate faster than the hexavalent chromium. 5. Graphite anode, can improve quality and increase stability of the bath. II. Bath composition and operating conditions 1 bath composition of raw materials standard range KB241 open cylinder salt 530g / L 500-560g / L KB241 KB241 add salt supplemented by stabilizer 90ml / L 80-100ml / L KB241 complexing agent 15ml / L 10 -20ml / L KB241 humectant 2ml / L 1-3ml / L KB241 additive 30ml / L 25-35ml / L 2. Operating conditions chromium 20-25 g / L 23 g / L pH value of 2.6 - 3.0 2.8 temperature 40- 50 ℃ 45 ℃ plating solution specific gravity 1.22 1.20-1.25 cathode current density 10-22A / dm2 16 A / dm2 anode current density of 2-8 A / dm2 5 A / dm2 anode: cathode (area ratio) of 1.5-2.0: 1 DC current voltage 9-15V filter needs stirring moderate air agitation exhaust recommended three. 1 bath formulation. 1/3 of the injected water in the cleaning bath, heated to 70 ℃, stop heating. 2. Was slowly added in small amounts KB241 open cylinder salt, stir, to ensure that the salt is dissolved. 3. Injecting water to the preparation of 80% by volume of the bath to control the temperature 70 ℃, stirring for 1 hour. 4. KB241 and KB241 added stabilizer additives, and mix well. 5. Join KB241 and KB241 complexing agent wetting agent, mix well. 6. Down to 45 ℃, adjust pH to 2.8. 7. At operating temperature, with a new nickel cathode wavy false about 2-4 A / dm2 current density electrolysis plating one hour you can try. Four. 1 device. Plating tank: PVC, ABS, polyethylene liner slot. 2. Anode: graphite anode and a titanium hook. 3. Temperature Control: titanium and titanium cooling pipe heating devices. 4. Rectifier: 12-15V, to stabilize the bath recommended configuration ampere-hour meter. Five. Function and control of raw materials 1. For best plating performance, at least for each class black chrome and add a variety of supplemental materials, such as work load is greater than 0.75 amps / liter supplement when the number should be more frequent, regular analysis of the ingredients and in accordance with ampere-hour consumption of supplementary black chrome raw materials for black chrome stability is very important. Record production line work is recommended ampere minute amount of gravity, pH, temperature and various raw materials supplementary information, with water consumption can be adjusted according to the proportion of the value. 2. KB241 open cylinder salt: for providing a bath of chromium ions, the bath Baume optimum value for each increase of one unit needs 26 plus 25-30g / L in the open tank salt concentration is too high will cause the bath crystals by anodic Passivation and play trachea been blocked, concentration is too low, it will affect the conductivity of the bath. 3. KB241 added salt: chromium salt bath supplement consumed, replenishment of 400-500 g / hr 1000 amps, low solubility of chromium salts, when added in small amounts is added slowly, added 7-8 g / l of salt added, to improve 1 g / l of chromium content. 4. KB241 Stabilizer: containing stabilizers and blackening agent, consumption of 1500-2000 ml / 1000 ampere-hours. 5. KB241 additives: Adjust the coating color uniformity, consumption of 50 to 100 ml / 1000 ampere-hours. 6. KB241 humectant: lower the surface tension of the coating, the consumption of 80 ml / hr 1000 amperes. 7. KB241 complexing agents: may increase the current density range, consumption of 500-650 ml / 1000 ampere-hours. 8. pH value: Available concentrated hydrochloric acid or concentrated aqueous ammonia to adjust the pH, is added per 2 ml / l of concentrated hydrochloric acid, pH value decreased 0.1 per 2 ml / l of concentrated aqueous ammonia, pH value increased by 0.1, concentrated hydrochloric acid or concentrated ammonia After stirring for 2-4 hours before the test with a pH value of pH meter bath. 9. Temperature: There are too low precipitation, high coating coverage seriously affected. 10. Characteristics of the bath: usually produce temperature control in 45-55 ℃, it can be regular bath with a carbon filter core, without affecting production, feed or processing cylinder preferably heated to above 60 ℃ incubated two hours and then cooled to normal temperature, usually 2-3 days of continuous production need to select the time and the bath was heated to make the components more complex. VI. Metal impurity control and influence when trivalent chromium plating solution by copper, zinc, nickel, iron, lead, metal impurity contamination when coating color and appearance will be subject to some degree of influence, at higher metal impurities, coating color gray When content is too severe, coating uneven color will appear white stripes, and artifacts from the bath into the rack fall into the slot, the main source of the metal impurities. 1. Regular cleaning tank, cleaning tank fell into the workpiece may have more to prevent the influence of metal impurities on the trivalent chromium plating color, most of the impurities such as zinc, iron, nickel, can be used to eliminate low current electrolysis. 2. When contaminated copper bath, high current gray area, with the increase of the impurity concentration of the copper coating gray. 3. When the bath contaminated by nickel, the current area will appear yellow coating, when the bath while the lower zone containing iron impurity was golden. 4. When the bath lead contamination, low current density areas appear white, poor throwing power bath, when content is too high, the high current density area coating adhesion fall, electrolytic methods can remove lead contamination.
