PROTECTOLINE100 Chemical Nickel Without Chromium Passivant

1.Product Introduction
The Protectoline 100 is a water-soluble organic passivatorThe Protectoline 100 can be diluted with water at any rate, and the liquid is alkalineprotective effect when the surface of the material is not dryIf the surface is already dry, no residue will be left, which will have no adverse effect on the next step2ApplicationProtectoline100 is an environmentally friendly passivator that can be used for chemical nickel plating of steel and ironThe Protectoline 100 is particularly suitable for flushing semi-finished products that have been degreased and etchedTheProtectoline 100 can be used in cold, hot and any related system that requires the addition of a passivant3Physical and chemical propertiessolution stratification: nodensity: 1,030 kg/m 3

2 water wash pure water washing
soaked chromium-free passivator
2 times washing hot pure water wash (temperature 80-90Degrees, cleaning time 30-60S (reference data)) Drying Note: 1 Before impregnating passivation agent, the product should be thoroughly cleaned to avoid the residual liquid contamination of chromium-free passivation agent, resulting in shortening its service life and other undesirable appearance of the phenomenon 2 The concentration formulation and impregnation time of chromium-free passivation agent can be adjusted appropriately according to different products or different deposition coating methods 3 After impregnating the chromium-free passivation agent, it is necessary to stop slightly, to avoid the chromium-free passivation agent out too much, resulting in shortening the passivation agent life cycle 5 Add method and concentration determination: solution added method
1 No chromium passivation agent in the process of use, when its concentration is too low or down to the lower limit of process parameters, it is necessary to appropriately add The Protectoline 100, it is recommended that continuous production every 2 hours to do concentration determination 2 Chromium-free passivation agent life cycle: When the ph value of chromium-free passivation agent is reduced to less than 9, it is recommended to do replacement treatment, but also according to the production situation to make appropriate adjustments concentration determination method
1.10 ml of solution was sucked into the flask 2 Add pure water to 100 ml and shake 3 Add 3 drops of 1% of the methyl orange indicator 4 The standard solution with 0.1N hydrochloric acid is titrated to the solution color from yellow to red for the end point consumption of 0.1NHcl is set to V, chromium-free passivation agent concentration is set to M (M as a percentage) M-RV (R is constant, value of 0.125) M-0.125-V
to exhaust 40 ml of 0.1N hydrochloric acid standard solution, The concentration of Thefoline 100 is 5% reference data concentration (ml) 0.54.0
