Kemchrome (Chromatising) Cue Forearm: Ash Wood

Kemchrome-350(Chromotising) Product DescriptionKemchrome-350 is specially formulated for the treatment of Aluminium and its alloys by immersion method. Kemchrome-350 gives a thin, smooth amorphous oxy - chromate coating, which is normally rainbow in nature of golden brown in colour. This coating is an excellent base for paint. This is also a good coating to avoid white rust on aluminum. Product Specifications a. Colour Golden Yellow liquid b. Chemical Composition Blend of Chromium and Additives c. Odour Slightly Pungent d.

Pollution Hazard Highly Hazardous Product Operating Data Concentration 3 - 5% Dip Time 2-5 min Temperature Room Pointage: TA Fa 9 - 14 ml 4 - 6 ml Product Operating Procedure: DegreasingPrior to Kemchrome-350 dip the job is to be properly degreased either by chlorinated vapour degreasing method or by caustic free degreasing solution. RinsingRinsing should follow degreasing, job should be properly washed with running water by dip or spray method. ChromastisingAfter water rinse the job should be dipped in 3 -5% of Kemchrome-350 solution for desired coating. Water RinsingJob should be rinsed properly. DryingAfter water rinsing, the job should be properly dried by hot air blowing. Product Application EquipmentsS. S. tank of 3 - 4 mm thickness. Testing and Control Procedure Free AcidityPipette out 5 ml of bat solution in a conical flask. Add 4-6 drops of Bromocresol green indicator. Titrate it against N/10 NaOH solution. The consumption of N/10 in burette will give the free acidity of the solution. Total AcidityPipette out 10 ml. Of bath solution in a conical flask. Add 50 ml of D. M. water and 10 ml of phosphoric/sulphuric acid mixture. Add 12 gms. of potassium lodide powder. Mix it thoroughly, add 15-20 drops of starch solution indicator. Titrate it against N/10 sodium thiosulphate. Colour of the solution will change from black to green. The consumption of N/10 sodium thisoulphate in burette will give the total acidity of the solution. Chemical ReplenishmentAdd 2.6 ltr. Of Kemchrome-350 for every 100 ltr. of water to raise the acidity pointage by 1. based upon organic compounds. Safety MeasuresKemchrome-350 is based upon organic compounds, so while handling, proper care should be taken. Protect your eyes and skin by means of goggles, aprons, gloves etc. If it comes in contact with skin and eyes, wash thoroughly with a flush off water and get medical advice.
