Nano Tao agent

First, the characteristics 1. Overview: This is a zirconium-based fluorine-based acid chemicals, can form a nano-ceramic coating on clean metal surfaces. Tao is the reactive process before a special formulated, can be transformed into film in the steel, zinc and aluminum surfaces using the form. It does not contain heavy metals, phosphates and any organic ingredients, can significantly improve the corrosion resistance of the metal coating, to extend its corroded time. 2. Economic benefits: room temperature (no heating) short reaction time (<60 seconds) do not do not need to do blocking treatment tables reconcile plus accelerator is not the consumption of wastewater treatment costs low, 1/5 for the traditional phosphate solution operating costs lower than conventional phosphate 3. Environmental Benefits: completely free of phosphate-free COD, BOD no heavy metal without sediment transport and cleaning 4. Process requirements: Stainless steel tanks deionized water or low hardness water Separate alkaline cleaning station 5. With a groove to be thoroughly rinsed with water after cleaning: measuring and groove PH value of water before adding a large number of F-6, with Additive-117 with slots reduce PH value of water to 6.5 or less. 6. Control Points: PH value 3.8 to 5.5 times the concentration of 1 to 7% from 20 to 120 seconds, room temperature spraying pressure 0.5 ~ 1.5bar 7. Process Description: Clean preferably suitable alkaline cleaning systems, refer to the relevant product specification should maintain a continuous overflow water to avoid contamination of deionized water rinse before conversion coating process rinsed with deionized water, should maintain a continuous overflow avoid contamination conversion coating process to maintain parameters within the recommended range of continuous overflow rinsed with deionized water, controlling the conductivity in 25μs / cm or less. Quick drying completely dry, indirect oven heated to 110 ~ 170 ℃ in bake 10 to 20 minutes 8. bath control: 8.1 PH value measured by the fluoride ion stability PH meter, PH precision test strips can also be used. (Eg Merck's 4.0 to 7.0 or 0 ~ 6.0PH paper) Recommended PH range: 3.8 to 5.5 PH value decreased 0.1: per 1000 liters bath, add 5.8 liters F-6. The PH value increased 0.1: per 1000 liters bath, add 95 liters Additive-116. Often the best test PH value, add a small amount of F-6 and Additive-116, to avoid a substantial adjustment in the number of PH value and chemical products.
