THIOUREA AR  is used in vulcanization accelerators. It is used as an auxiliary agent. It is used in silver – gelatin photographic prints. It is used in diazo paper, light – sensitive photocopy paper.

LIME Marine does not corrode, erode, attack, oxidize or have other deleterious affects on virtually any metal or materials found in marine water systems such as: BRASS, IRON, LEATHER, CERAMIC ,WOOD, FIBER, PLASTICS FIBERGLASS, COPPER, STEEL, TITANIUM ,COPPER NICKEL ,RUBBER, GLASS, GELCOATS PAINTED SURFACES.

LIME Marine is an electrolyte, as are most cleaning agents. An electrolyte is any liquid that will transfer small electrical currents. Examples: salt water, vinegar, Coca-Cola. An electrolyte may cause plating in some types of equipment. This means a transfer of small amounts of one metal onto another metal according to the galvanic corrosion chart. In some instances, a thin coating of copper may be plated onto a steel drum while circulating an electrolyte such as RXLYME Marine. The only time plating occurs is when two dissimilar metals are in an electrolyte solution.

It is recommended, but not mandatory, that the LIME Marine solution be thoroughly mixed before using. Some settling of a dark precipitate may occur, resulting in an amber colored liquid, but has no negative affects upon the performance of the solution.

RXSOL-40-1048-025 should not be used on Aluminium, Zinc, Tin, or any Galvanized Surfaces for which a special grade cleaner should be used. Chemical Cleaning Module Rx cleansers has developed a 280 litres capacity cleaning module, primarily designed for use with chemical acid solvents for descaling boilers, calorifiers, heat exchangers & other types of equipment where rust & scale form RXSOL-11-1008--DC Boilers, See Rx cleansers Practical Application Manual.

Formation of Calcium Sulfate is main cause for SCALE formation :::

The principal problem potential posed by sulfate ions in water is the possibility of calcium sulfate scale formation.  Precipitation of calcium sulfate can occur when high concentrations of both calcium and sulfate exist simultaneously.  There are three primary areas of water treatment in which calcium sulfate precipitation may occur boilers, cooling systems, and ion exchangers operating in the hydrogen or acid mode.

In boilers, calcium sulfate scale formation has been reduced to a minimum by modern treatment practices.  The low hardness levels largely preclude calcium sulfate boiler scale.    By contrast, cooling systems are subject to calcium sulfate scale deposition because the makeup is usually not treated for hardness removal.  Cooling water is usually treated with sulfuric acid for pH control, and the makeup is cycled, i.e. concentrated.  Calcium sulfate scale deposition can  result unless the cycles of concentration are properly controlled in conjunction with the proper use of scale control chemicals.  Cation ion exchangers regenerated with sulfuric acid also can pose a major calcium sulfate problem. Calcium sulfate precipitation can be avoided by controlling the acid concentration and the flow rate through the exchanger.
