Kemphos-331(zinc Nickle Accelerated Phosphating Ch Cue Forearm: Ash Wood

Kemphos-331(Zinc Nickle Accelerated Phosphating Chemical)(Zinc Nickle Accelerated Phosphating Chemical) Product DescriptionKemphos-331 is an accelerated hot dip Zinc/Nickel Phosphating process which produces fine smooth coating on steel and zinc surfaces. Smooth coating serves as good base for paint and reduce consumption of paint and retains paint gloss. Kemphos-331 processes are easy to operate and are controlled by simple tests requiring no chemical knowledge. No fumes and odours are given off. Kemphos-331 meets the requirements of specification WPN/GEN/3 class II acclerated process and the requirement off IS:3618:1966 class B. Product Specifications   a. Colour Light Green Liquid b. Chemical Composition Blend of phosphates, nitrates, zinc, nickel, activators etc. c. Odour Slightly Pungent d. Foaming Tendency Nil e. Reliability Good f. Handling Avoid Skin Contact g. Solubility Good h. pH Acidic Range I. Toxicity Nil j. Flash Point Nil k. Pollution Hazard Moderate Product Operating Data   Concentration 3 liter Kemphos-331 and 25 gms. Accelerator per 100 ltr. Water. Pointage 32 -37 ml Temperature 60 - 70oC Immersion time 5-10 min Accelerator Pointage 2 -6 ml Coating Weight 400- 600 mg/sq.ft Product Operating Procedure3% solution of Kemphos-331 is made with water and is heated upon 70oC and 50 gms. Of accelerator is added per 100 ltr of bath. After bath aging with steel wool for 15 - 20 min. production can be start. Kemphos-331 coating gives excellent foundation for paint the coating obtained are sufficiently fine to enable a good gloss (to be achieved with sufficient paint systems.) Product Application EquipmentsKemphos-331 tank should be fabricated with 3 to 4 mm thick M. S. plates with continuous convection current hating system. Testing and Control Procedure: Total AcidityPipette ut 10 ml. Of the bath solution in a conical flask. Add few drops of Indicator Phenolphthalein and shake it well. Titrate against N/10 NaOH until permanent pink colour persists. The number of ML N/10 NaoH added is the pointage of the bath. Adjust the pointage by adding Kemphos-331 to the bath. For each one pointage less add 125 ml of Kemphos-331 per 100 ltr of bath. Free AcidityPipette out 100 ml. Of the bath solution in a conical flask. Add few drops of methyl orange Indicator and mix by shaking. Titrate it against O.N/10 NaOH solution until colour charges to yellow. The number of ML of N/10 NaOH added is a free acidity of phosphating bath. Accelerator Pointage TestingPipette out 10 ml bath solution into flask. Add 5 ml of concentrated H2SO4 and mix it well. Titrate it against with N/10 KmNO4 solution to a pink colour which will persist for few seconds. Normal limits for Kemphos-002 (accelerator) titration is 2.6 ml. Lower limit is preferable. Prior to titration starch Iodide paper should be positive. Replenishment.  Approximately 30 ml. Of 25% Kemphos-002 (accelerator) solution in water should be added to increase the Kemphos-002 (accelerator) titration by 1 ml. Chemical ReplenishmentRestore the bath to the working level by adding water to makeup evaporation loss and drag out losses. Check the Kemphos-331 pointage. Safety MeasuresKemphose-331 is an acidic liquid material, and while handling proper care should be taken. Protect eyes and skin by means of goggles, aprons, gloves, etc. If it comes in contact with skin and eyes wash thoroughly with flush off water and get medical advic.e General InformationCorrosion Resistance: Excellent.
