Protectoline100 chemical nickel chromium free passivator

1 Product introduction protectoline 100 is a water-soluble organic passivator without nitric acid Protectoline 100 can be diluted with water in any ratio, and the liquid is alkaline When the surface of the material is not dry, protectoline 100 has a protective effect If the surface is dry, there will be no residue left, which has no adverse effect on the next operation 2 Protectoline 100 is an environmentally friendly passivator for electroless nickel plating of steel and iron parts Protectoline 100 is particularly suitable for flushing semi-finished products after degreasing and etching treatment Protectoline 100 can be used in cold and hot systems and any related system requiring passivation treatment 3 Physical and chemical characteristics: solution stratification: no density: 1030 kg / M 3 solvent: Deionized water (pure water) storage temperature: > - 10 ℃ concentration: 7-9% (reference data) pH: 10-11 Process time: 3-5 minutes (reference data) capacity: 100-150 DM2 / L (reference data) 4 Process flow: Plating Ni / electroless plating Ni 2 times of water washing, pure water washing, chrome free passivator 2 times of water washing Hot pure water washing (temperature 80-90 ℃, cleaning time 30-60s (reference data)) drying remarks: 1 Before the passivator is impregnated, the product shall be thoroughly cleaned to avoid pollution of chromium free passivator by residual liquid, resulting in shortening its service life and other appearance defects 2 The concentration preparation and immersion time of chromium free passivator can be adjusted according to different products or deposition methods 3 After impregnation with chromium free passivator, it is necessary to make a little stagnation to avoid excessive chromium free passivator and shorten the service cycle of passivator 5 Adding method and concentration determination: solution adding method 1 When the concentration of chromium free passivator is too low or falls to the lower limit of process parameters in the use process, protectoline 100 should be added appropriately It is recommended to conduct concentration determination every 2 hours in continuous production 2 Service cycle of chromium free passivator: when the pH value of chromium free passivator drops to less than 9, it is recommended to replace it, or adjust it according to the production situation Concentration determination method 1 Suck 10 ml solution into the flask 2 Add pure water to 100ml and shake 3 Add 3 drops of 1% methyl orange indicator 4 Titrate with 0.1N hydrochloric acid standard solution until the color of the solution changes from yellow to red The consumption of 0.1N HCl is set to V, the concentration of chromium free passivator is set to m (M is the percentage ratio), M = RV (R is a constant, the value is 0.125), M = 0.125 * v the reference data is to exhaust 40 ml of 0.1N hydrochloric acid standard solution, and the concentration of protectoline 100 is 5% Concentration (%) hydrochloric acid dosage (ML) 0.5 4 1 8 2 16 3 24 4 32.0 5.0 40.0 7.0 56.0 6 Material protection The mechanism of this chromium free passivator is active adsorption sealing to achieve surface protection, without any adverse effect on the product appearance, and does not affect the subsequent re processing (such as welding, wear resistance and other physical properties) When the material surface is in a humid environment, the protective effect of protectoline 100 is prominent If we want to achieve long-term protection, we must adopt relevant protection measures 7 Store and package the product in a cool and dry place Packing: 25L / barrel.
