Electroless nickel-chromium alloy plating liquid，Environment-friendly chemical nickel-chromium plating，Nickel-chromium alloy for metal plating，Non - cyanide nickel chrome plating agent，Nickel-chrome plating agent，Electroless hard nickel-chromium plating

product number: Q/YS.616 (yishun brand)

the purpose and advantages:

 by this product out of nickel chrome plating layer, porosity, less dense membrane layer, 300 ℃ test not craze, coating has excellent corrosion resistance, heat resistance, acid and alkali resistance, resistance to chemical corrosion, more important is the advantage of excellent weldability. Widely used in electronic components. Due to the introduction of chromium in the coating, the weldability is greatly improved. The coating can also be used as the contact containing gold for electrical components such as switches and knife blades.

product index: agent A is A green liquid with no odor

Agent B is a pale yellow (nearly colorless) clear liquid with no odor

Agent C is a transparent additive with odor

usage:

（1） open cylinder: A agent: B agent: deionized water (water) = 1:2:7, heated to 90 ℃ + / - 5 ℃, USES glass, ceramics, heat resistant plastic containers.

（2）The workpiece to be plated nickel-chromium alloy for pretreatment: polishing, deoiled acid activation, etc.

（3） will be treated as before good artifacts (metal parts), with 90 ℃ ~ 100 ℃ hot water soak clean preheating 10 to 20 seconds, remove immediately to 90 ℃ + 5 ℃ for basic, such as chemical nickel plating chromium to use aluminum for chrome plated after activation treatment.

（4）Of coating thickness can be controlled by time, plating speed of 20 / h.

control and management of plating solution

(1) nickel plating temperature control at 90 ℃ + 5 ℃

(2) plating solution PH value control in 9.0 ~ 9.4, with ammonia or dilute sulfuric acid adjustment

(3) the midway consumption to be supplemented by A and C, A:C= 1:1 add

Other processing：Chemical Plating Liquid Train、Environmental degreer and rust remover、Brass Green Chemical polishing Agent、Electroless plating of real gold on copper surface、Strong oil stain removal agent、Copper、chromium and nickel stripping agent
