DG-11 is an easy to use acid compound for removing water scale and iron dioxide deposits. It is inhibited to pro- tect metal surfaces. This product is suitable for removal of calcium carbonate and magnesium salts as well as ferrous oxides from metal surfaces.marinechemicals,marinechemicals,marine chemicals istanbul,marine chemicals,marine chemicals,marine chemicals istanbul,deniz kimyasalları, marine chemicals istanbul,marine chemicals, Features: DG-11 is recommended for descaling boilers, evaporators, condensers, heaters and coolers. It may also be ap- plied for scale removal from steam pipes and air conditioners. Benefits: Fast and efficient removal of scale and iron oxides. Contains descalant accelerator to increase reactions. Con- tains protective corrosion inhibitor against attack on ferrous metals. Can be used on most common metals. Easily rinsed, non volatile, water – soluble. Usage: DG-11 can be used by all conventional methods. However, recirculation and soaking methods have proven to be the most efficient. First of all, inspect the components to be cleaned and if they are contaminated with oil, sludge or any other similar product, use either DG-01 – Solvent Based Oil And Grease Remover as pre-cleaners. The amount of DG- 11 to be used depends on the extent and nature of contamination. For general cleaning, use a solution of 10-30% of DG-11 in fresh water. Remember that DG-11 is an acid so you should always pour acid into the water, never do the reverse! Once cleaning is complete, rinse thoroughly with plenty of fresh water and also rinse with a solution of 1-2% of BT-02 – Alkalinity Control in fresh water. This step is necessary to make steel surfaces passive and to neutralize any remaining acid. Aluminum, zinc, tin and galvanized surfaces should be avoided. A. Recirculation Method Heat Exchangers, Evaporators, Condensers Heat a 10-30% solution of DG-11 in water for best results (up to 50oC). Recirculate the solution through the heat exchanger by use of a pump for at least 6-10 hours and maintain solution temperature if possible. Periodically test solution acid strength and add DG-11 as required. Rinse off by connecting the heat exchanger to a supply of fresh water. The last step involves circulation of a 1-2% solution of BT-02 – Alkalinity Control for a minimum time of 3 hours or until a neutral pH is obtained. B. Cooling Water Systems Follow same procedure as above. A sufficient quantity of chemical will be required to maintain acid strength throughout the cleaning operation. Place scale samples in easily observed positions to monitor the progress. C. Boiler Scale Remover Prepare a DG-11 solution in a mixing tank (no more than 60-70oC) and either arrange gravity feed of the solution directly into the boiler or connect the mixing tank to the circulation line between the water blow down flange and the pump. Use auxiliary feed line to feed the solution into the boiler so it flows via the economizer to the steam drum and then to the water drum, through the boiler tubes and subsequently out of the blow down connection. Secure all connections, half fill the boiler with fresh water and slowly add the product to obtain a solution of 10-30% and then start the circulation pump. Maintain the circulation for 8-16 hours, making sure that the acid strength of the solution remains stable by checking periodically and adding product as required. Periodically test the solution strength. If it quickly neutralizes even after DG-11 addition, drain off and re-start with a fresh solu- tion. Rinse thoroughly the boiler with fresh water and circulate a 1-2% solution of BT-02 – Alkalinity Control for at least 3 hours or until a neutral pH is obtained. D. Soaking Method This method will produce acceptable cleaning results where recirculation, especially on heat exchangers, cannot be arranged. Disconnect exchanger from circuit and drain. Use one of inlet/outlet connections or cleaning plugs to provide a steam feeding pipe into the exchanger. Leave uppermost connection/plug open for ventilation. Fill the exchanger with warm water. Check the acid solution strength. Allow the product to act and periodically ap- ply steam to maintain temperature. Thoroughly flush with fresh water and as a final step use a solution of 1-2% of BT-02 – Alkalinity Control to neutralize the remaining acids. Further Technical Data:
