The L being preferred for maximum tank life. In all cases approved welding techniques must be used. Process piping and pumps should be constructed of or stainless steel alloys. Various formulations of plastic pipe may be used with recommended support spacing, Schedule being generally recommended. PVDF may be used for all expected operating temperatures and may reduce the rate of scale buildup in process piping. The nozzles should be fabricated from stainless steel. Heat exchanger plates should be polished stainless steel.
If gas fired burner tubes are used, they should be made of Schedule mild steel pipe or equivalent. All process circulation pump seals, valve seats, door seals, etc. EPDM may be used, but its life will be shorter. Chemical feed pump parts and other elastomers which may come into contact with the concentrated replenishing chemical should be Viton or Teflon. Again, EPDM may be used, but its life will be shorter.
Support equipment available from Henkel Technologies for this process includes chemical feed pumps, level controls, transfer pumps and bulk storage tanks. Your local sales representative should be consulted for information on Henkel Technologies automatic process control equipment for this process and any additional questions.
Surface Preparations Cleaning: All metal to be treated with the processing solution must be free from grease, oil and other foreign matter before the treatment. Water Rinsing: After cleaning, the metal must be thoroughly rinsed with water. The rinse should be overflowed continuously at a rate which will keep it clean and free from scum and contamination. Deoxidizing: Aluminum with corrosion products or heavy oxide coated surfaces should be treated with a deoxidizer prior to the conversion coating treatment step.
The deoxidizing step should follow the water rinse and should itself be followed by a separate water rinse. Our representative can recommend the correct deoxidizer to be used. Finally, add sufficient water to bring the solution up to the working level and then heat the operating temperature. Operation: Time: 15 seconds to 3 minutes.
For the treating time selected, the bath should produce a light, iridescent golden to tan colored coating on aluminum. The desired coatings may also be obtained by adjusting the pH. The initial charge and replenishment data contained herein are normal for most installations; however, our representative may suggest a deviation from this data if indicated by local conditions.
Testing and Control Never pipet by mouth, use a pipet filler. Concentration: Pipet a 5 ml sample into an iodimetric flask and dilute to approximately ml with water. Add about 10 ml of Reagent Solution 49 in 5 ml increments to the lip of the flask, raising the stopper slightly after each addition to allow the acid to run into the flask. Rinse the lip several times with water and replace the stopper. After the sample has settled for approximately one minute, titrate with Titrating solution until a straw color is obtained.
Do Not rezero the burette. Add several ml of Indicator 10 and continue the titration until the blue-black color disappears. The ml of Titrating Solution used is the bath concentration value in points ml. The optimum pH for this bath is between 1. It is recommended that no large bulk additions to nitric acid be made.
In certain instances, the pH of the bath will continue to decrease several hours after an addition of nitric acid as the solution seeks equilibrium. Accordingly, small adjustments in pH should be made allowing 15 minutes to elapse before subsequent adjustment.
If the amount of nitric acid specified is insufficient to maintain the bath pH, the pH will rise causing a reduction in color intensity of the coating. If this occurs, increase the amount of nitric acid per addition in small increments to a maximum of 1.
After Treatment Water Rinsing: After the conversion coating treatment, the work is thoroughly rinsed in cold water. The rinse should be continuously overflowed and the overflow should be regulated with the rate of production so that the main body of the rinse never becomes excessively contaminated. Drying: The treated articles should be dried immediately after the post treatment. Enough heat usually remains from a hot post treatment to cause heavy gauge articles to dry satisfactorily.
If the post treatment is not heated or the articles do not dry satisfactorily, an indirect fired drying unit or any other means which will not contaminate the treated surface with fumes, oil, or partially burned gases may be used. Products with cavities or pockets which trap moisture should be blown dry with clean, compressed air.
Moisture spatters should be dried with clean cloths. Dried, unfinished parts should not be handled. If handling if necessary, plastic or clean often changed cotton gloves should be used. Waste Disposal Information: Applicable regulations covering disposal and discharge of chemicals should be consulted and followed. The processing bath is acidic and contains chromium and ferricyanide.
Waste treatment and neutralization will be required prior to discharge to the sewer. Precautionary Information When handling the chemical products used in this process, the first aid and handling recommendations on the Material Safety Data Sheet for each product should be read, understood and followed.
Open containers in a well ventilated area. Keep containers closed when not in use. The processing bath contains chromic acid in excess of 0.
The following statement, or one similar to it, should be included as part of the process tank labeling. Overexposure may create cancer risk. HCl - 1 - Thermometer, Floating - 1.
