Etching processProcessMainly divided into pre-treatmentInspection, cleaning, oil spraying, developing, oil sealing, etching, quality controlRokudoThe work process, for the metalEtching processThe required etching solution, i.e., phosphoric acid and hydrochloric acid, is relatively large in concentration, and if properly handled will cause great pollution to the environment, so how is it handled by the etching manufacturer, Zhuolida? Metal etching will mainly produce acid, alkali, ferric chloride chemical composition, in the process of metal etching produced alkaline wastewater and acidic wastewater intertwined to achieve the purpose of neutralization treatment, in order to improve the balance of acid and alkali, Zhuolida etching plant using24-hour online monitoring and regeneration cycle system of the medicine water, testing the stability of the medicine water and testing the PH value high and low, so that the PH value to meet the national standard emission standards, and at the same time to clean up the metal ions, through the precipitation method, the discharge of clear water, the chemical reaction generated by ferric chloride can make the polluted environment produce yellow rust, in order to remove the pollution of ferric chloride on the environment, let the third-party processing company to recycle, and the wastewater generated by ferric chloride through the lime milk again to neutralize the treatment, as far as the role of precipitation can also play the role of cohesion.

In order to lead by example in protecting the environment.Zhuolida Etching FactoryPutting into production a self-built sewage treatment system.24-hour monitoring to improve the yield rate, so that the drug water recycling, truly environmental protection, energy saving and emission reduction.
