Supply black nickel rust inhibitor for electroplating

Introduction: 73145-4# water soluble antirust agent is a kind of brownish red liquid, which is not easy to burn
It can form a dense protective film on the surface of metal (the workpiece has better effect after electroplating, and the antirust effect is obvious when used on black nickel plating)
It has strong antirust, anti Fushi and anti discoloration effects
It is easy to use, easy to operate and simple equipment
It is suitable for metal stamping iron parts, Anti rust and anti Fushi treatment of various standard parts after plating (such as nickel, chemical nickel, blackening, black nickel, tin, zinc, chromium, etc
) is applied to electroplating, continuous electroplating and chemical plating
The antirust ability and salt spray resistance of the treated workpiece can be greatly strengthened, and the surface gloss is good
It will not stick together and affect the conductivity and welding

 
Operation process:
1
Electroplated workpiece → 2
73145 passivation and sealing → 3
Self drying or drying (directly drying without washing water until the water drops on the surface just disappear
Too long drying time will affect the appearance and salt spray resistance) → packing

 
Operation process:
Concentration: 2-20% (i
e
2-20 liters of 73145 sealant and 80-90 liters of pure water in 100 liters of working fluid)
Working fluid temperature: normal temperature to 60 ℃
Time: 1-5 minutes (if time permits, it is recommended to soak for more than 3 minutes)
Drying temperature: the recommended drying temperature is 40-100 ℃ (it is strongly recommended that the soaked workpiece can be dried directly without washing with water)
 
Concentration usage parameters:
Concentration / surface state of workpiece after treatment / salt spray resistance (neutral)
5% (it is recommended to dilute with pure water) / dry / no rust in 18-28 hours
10% (it is recommended to dilute with pure water) / dry / no rust in 24-50 hours
20% (it is recommended to dilute with pure water) / dry / no rust for 50-124
5 hours
 
1
Shake the 73145 stock solution evenly before use, and then pour it out to open the cylinder

2
The working fluid that has not been used for a long time shall be stirred evenly before operation
3
The above data are only for reference (due to different plating layers, plating types and workpiece materials)
4
The maintenance of working fluid shall be calculated and added according to the brought out volume
5
It is recommended to replace the working fluid after one week of use

6
If there are spots on the surface of the workpiece after treatment, reduce the workpiece and drying temperature to 30-35 ℃, and operate the spotted workpiece again without re electroplating
7
If you have any problems during operation, please call to solve them
 
 
Note: 1 If the hanger is directly put into this product for treatment, please clean it and then put it into the plating bath, so as not to bring Yao water into the plating bath and affect the plating bath
2
If the test results fail to meet your requirements, please tell us the reason so as to provide a more suitable model

 
Storage: please put it in a cool and ventilated place, away from high temperature, open fire and inflammables
