Mr. Liu in Huizhou, Guangdong Province, is an electroplating factory owner engaged in the galvanization processing of various hardware products and stamping parts. Recently, Mr. Liu found that the black passivation solution always exceeds the phosphorus standard when discharging wastewater, as this violates the discharge standard of the electroplating park, so Mr. Liu would like to replace a phosphorus-free black zinc passivation solution in a hurry.
One day, Mr. Liu saw Bigely black passivate BZ-217 for galvanizing when he was searching on the internet, so he inquired about the characteristics of this passivate and the reason why the phosphorus content exceeded the standard in wastewater discharge. Bigely engineers in a detailed understanding of Mr. Liu's production, explained that because some passivation solution due to the formula contains phosphorus compounds, and phosphorus does not participate in the passivation of the reaction, so the phosphorus will be in the passivation solution slowly accumulated, when the passivation solution wastewater in the discharge of phosphorus exceeds the standard situation.
But this black passivate BZ-217 for galvanizing is formulated without phosphorus compounds, and the passivate is phosphorus free, so there is no phosphorus exceeding the standard in the waste water discharge. In addition, this black passivate BZ-217 can obtain a passivate film with a uniform black bright film, and the passivate film has good bonding force and excellent corrosion resistance, which is able to meet the black passivation treatment of roll and hang galvanizing of workpieces with different substrates. After understanding, Mr. Liu decided to buy a barrel to try first.
Under the guidance of engineers, Mr. Liu used this galvanized black passivate BZ-217, passivation solution is indeed non-phosphorus, the discharge of wastewater also meets the standards. And the workpiece after passivation film uniform black bright, adhesion and corrosion resistance are better than before, which can meet the customer's high-quality requirements for the workpiece, the production of more trouble-free and labor-saving. Soon, Mr. Liu placed another order and signed a cooperation agreement with Bigely.
Therefore, when the black passivate solution we use in the production process of galvanizing appears to have excessive phosphorus in wastewater discharge, try Bigely black passivate solution for galvanizing, BZ-217, which does not contain phosphorus and has a good passivation effect.
