Antifreeze
APPLICATIONS
Antifreeze Special is free from amine, phosphate and nitrite etc. And uses as engine Antifreeze as well as coolant. This product is based on ethylene glycol. It contains a corrosion inhibitor, salts of organic acids and silicates (Si-OAT). It protects all metallic parts against corrosion and deposits in the cooling system.
Benefit
The product protects all parts of cooling system from frost, oxidation and overheating.
It has long-term protection against corrosion for all materials used in the engine and radiator construction, such as cast iron, aluminium, copper and solder alloys as well as a good compatibility with hoses, seals or plastics.
It contains carefully selected amine, nitrite, boron and phosphate free inhibitors and is therefore environmentally friendly.
Typical descaling cleaning procedure :
1st Stage : Take ‘RXSOL-11-1053-010’ weblink ( http://rxmarine.com/Alkaline-Descaler ) and mix with water in the ratio of 1:6 (One litre of RXSOL-1053 and six litres of water). Circulate the solution or immerse the equipment in this solution for 2 hrs. This will be helpful in loosening the hard deposited scale.
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.
