With the enhancement of people's awareness of environmental protection, galvanized trivalent chromium passivators are widely used due to their environmental protection, good corrosion resistance, and simple wastewater treatment.However, some trivalent chromium passivators on the market still have the problem of high cost. What is the reason?
Bigolly Technology made an analysis based on the field experience and the characteristics of the product galvanized trivalent chromium passivators BZ-212, there are three main reasons:
1. The formula design of the trivalent chromium passivator used is unreasonable.This is prone to the phenomenon of proportional imbalance in the production process, resulting in fogging and yellowing of the workpiece after passivation.In order to solve the fault, the tank solution can only be reconstituted, thereby increasing the cost.
2. The trivalent chromium passivator used has low tolerance to impurities.During the production process, the concentration of zinc ions in the passivation solution will continue to rise. Occasionally, if the workpiece is dropped into the bath and not salvaged in time, the iron ions will rise. Too much zinc and iron impurities in the bath will seriously affect the performance of the passivation solution.When the trivalent chromium passivator we use has a low tolerance for impurities, due to the high failure rate, the production can only be maintained by updating the working fluid, which greatly increases the production cost.
3. The trivalent chromium passivator used is not prepared with pure water.Some private workshops do not have legal factories. In order to reduce investment and save costs, they use groundwater or tap water to prepare potions!Some private workshops do not have legal factories. In order to reduce investment and save costs, they use groundwater or tap water to prepare potions!For example, some trivalent chromium passivators contain fluoride ions, and calcium in hard water will form calcium fluoride precipitation with fluorine, resulting in poor use of the passivation solution and high use costs.
Therefore, these are the 3 reasons for the higher production cost when using galvanized trivalent chromium passivator.If you are interested in galvanized trivalent chromium passivators, please contact Bigolly customer service, you can get free samples and detailed technical information!
