Model/Specification

SpecialProperty

Black nickel saltCSuitable for decorative electroplating black coatings, which can reproduce the surface condition of the substrate, producing a glossy black coating on a bright substrate surface and a matte black coating on a dull substrate surface.

Black nickel saltCIt has advantages such as uniform color, easy control, good coating adhesion, and low residue, suitable for both hanging and rolling plating.Usage conditions

Black nickel saltCTemperature: Temperature has a significant impact on current density. Higher temperatures are beneficial for increasing current density and shortening plating time, but excessively high temperatures can cause discoloration, especially in automatic line production or large area plating and rolling nickel, so the temperature should not be too high.1Value:When the value is low, the color is light, hardness is high, and pinholes are likely to occur.When the value is high, the color is deep, butif the value is too high, it may cause the coating to peel off, so caution is needed.Temperature/°CUsage conditions
Black nickel blending salt: When
pHnormal, but the coating is not dark enough, it is advisable to add black nickel blending salt.pHExcessive addition will cause uneven coating color.pH(Low electric area appears yellow or blue)pH. At this time, it is advisable to add black nickel positioning salt.
Adding can improve.pHBlack nickel positioning salt: Usually does not need to be added, only added in moderation when the low electric area appears yellow or blue. Excessive addition will make the coating color lighter; in this case, an appropriate amount of black nickel blending salt can be added.3L5Temperature/Stop using the plating solution for a period of time. When resuming use, it is advisable to heat and stir to completely dissolve the crystallized sediment at the bottom of the tank, and the anode contact points should be cleaned.Packagingand storagekgbarrel, stored in5Temperature/a cool and dry warehouse, direct sunlight is strictly prohibited.
High temperature and heat, must be sealed after use.
停止使用一段时期之镀液。当再次恢复使用时，宜加温并搅拌，使槽底之结晶沉淀物完全溶解，同时应擦洗阳极电接触点。
