TCR-300 Trivalent White Chromium Plating Process
1. Environmentally friendly products, no hexavalent chromium, simple wastewater treatment.
2. Uniform color, beautiful appearance, good coverage and uniformity.
3. The plating solution does not contain organic solvents; the tolerance of sulfate and chloride ions is good.
4. When electroplating power will not have adverse consequences, the deposition rate is faster than the six valence chromium.
5. The use of trivalent chromium special graphite anode can improve the quality and increase the stability of the plating solution.
TCR-1 Environmentally friendly and highly corrosion-resistant chrome plating process
1.CRH-1 is a crack-free chromium plating process with superior corrosion resistance, which greatly exceeds the hexavalent chromium process (hexavalent chromium plating has microcracks).
2.CRH-1 coating is white bright color.
3. The internal stress of the coating is smaller than that of the hexavalent chromium process, and the hardness is higher than that of the hexavalent chromium process. Moreover, the hardness of the coating increases after heat treatment, while the hardness of the hexavalent chromium process coating decreases after heat treatment.
4.CRH-1 is a truly environmentally friendly chrome plating process with practical significance.
TCR-320 Black Steel Trivalent Chrome
1.TCR-320 black steel trivalent chromium electroplating process can obtain unique black finish coating on the surface of nickel coating.
2.TCR-320 black steel trivalent chromium plating process has the following advantages:
-Does not contain toxic substances.
-Can produce unique black plating.
-Stable color appearance in a wide working range.
-Good covering ability and plating ability.
-No adverse consequences caused by power failure, high tolerance for impurities such as sulfur and chlorine.
TCR-330 Trivalent Black Chrome Plating Process
1. Environmentally friendly products, no hexavalent chromium, simple wastewater treatment.
2. The coated carbon black is glittering and translucent, beautiful, with good covering ability and uniformity ability.
3. The plating solution is stable and has good tolerance for sulfate and chloride ions.
4. When electroplating power-off will not have adverse consequences, the deposition rate is faster than hexavalent chromium
5. The use of high-density graphite anode can improve the quality and increase the stability of the plating solution.
TCR-360 trivalent black chrome plating process
1. Environmentally friendly products, no hexavalent chromium, simple wastewater treatment.
2. The coated carbon black is glittering and translucent, beautiful, with good covering ability and uniformity ability.
3. The plating solution is stable and has good tolerance for sulfate and chloride ions.
4. When electroplating power-off will not have adverse consequences, the deposition rate is faster than hexavalent chromium
5. The use of high-density graphite anode can improve the quality and increase the stability of the plating solution.
TCR-600 Sulfate trivalent white chromium plating process
1.TCR-600 sulfate trivalent chromium plating process is a low concentration, environmentally friendly chromium plating process, no hexavalent chromium is produced under normal conditions, which can prevent chlorine precipitation in chloride system from harming the environment and human body.
2. The plating solution has good dispersion and covering ability, which can be adapted to the processing of complex shape workpieces and deep hole parts; at the same time, the plating solution is less corrosive and can be adapted to the electroplating of zinc alloy parts.
3. The coating is white and slightly blue, close to the hexavalent chromium coating, and the corrosion resistance is better than the hexavalent chromium coating.
4. Excellent process stability, low cost, easy maintenance, no need to use ion exchange method to remove impurity metal ions.
CR-AB Low temperature and high efficiency self-adjusting chrome plating additive
1. Has excellent dispersion ability and deep plating ability.
2. The cathode current efficiency is high, up to 25-28%.
3. It can be produced at low temperature or even at room temperature.
4. Use low concentration of chromic anhydride.
5. Automatically adjust the sulfuric acid content, the solution has good stability and easy management.
CR-841 Chrome plating activator
1.CR-841 chromium plating activator can replace chromic acid type chemical activator, the bright nickel layer before chromium plating cathode electrolytic activation.
2. The required current density is low, which can completely prevent the occurrence of Milky White chromium layer and stains due to the passivation of light nickel coating (insufficient water washing, or the interval between nickel plating and chromium plating is too long, light nickel coating passivation will occur.)
1. dedicated to decorative chrome and hard chrome process after plating cleaning.
2. Thoroughly remove the residual chromic acid solution on the workpiece.
3. Reduce the amount of cleaning water and the discharge of chromic acid wastewater.
1. The cathode current efficiency is as high as 22-26%, which is 2-3 times of the traditional standard chrome plating process, saving energy.
2. The use of current density wide 30-90 amperes/square decimeter can be, the deposition rate is fast.
3. No fluoride, no corrosion to the low current density area of the substrate, no corrosion to the anode.
4. The microhardness of the coating can reach 1000-1100KHN100.
The number of microcracks in the coating can reach 1000/inch, thus improving the corrosion resistance.
6. The coating is bright, smooth and meticulous, with uniform thickness and good deep plating ability.
7. The plating solution is stable, easy to operate and easy to maintain.
1.DF-501 is a perfluorinated surfactant, which has a good effect on the inhibition of chromic acid mist.
2. Can also be used as other acid, alkaline plating tank or electrolytic tank of the fog inhibitor.
3. The addition amount is small and the use cost is low.
