Oat Antifreeze Additive Package Metal-Free Arganic Acid Corrosion Inhibitors for Antifreeze

Product Description

1. Product Introduction of Antifreeze Coolant Additive
This product AC7040 is a kind of Antifreeze Coolant Additive Package by organic acid OAT technology. The coolant produced by this additive package has a good antirust and anticorrosion effect on the metal of the cooling system of light and heavy-duty vehicles, such as solder, cast aluminum, cast iron, steel, brass, copper, and so on, which have a superior antirust function, especially the corrosion resistance of wet cylinder liner of heavy-duty vehicle. Green environmental protection, biodegradation 100%. The engine coolant produced by the coolant compound agent has the advantages of superior performance, convenient use, high production efficiency, and low production cost. It can produce coolant in accordance with NB/SH/0521-2010, GB29743-2013 standards without complex equipment and professional personnel.


2. Application of Antifreeze Coolant Additive
Mainly for producing ethylene glycol type low and high-load engine coolant/antifreeze. Compound Additives for Corrosion Inhibition with organic type coolant formulated and in accordance with the product blending process of the vehicle coolant can meet domestic, international product standards and OEM products Industrial standard performance requirements.

3. Product characteristics for the production of coolant:
Long life:
using organic acid technology, the consumption speed of additives is greatly reduced, the service life of coolant products is prolonged, and the maintenance life of coolant products is 5 years.

Performance:
Superior antirust, anti-corrosion performance: contains a high-efficiency organic acid additive, has better rust prevention ability to all kinds of metals in engine cooling system, especially for heavy load vehicle wet cylinder liner corrosion resistance is greatly improved.

Superior protective performance of aluminum alloy:
Excellent organic acid adsorption and rust prevention technology can eliminate cavitation corrosion of aluminum alloy and corrosion damage caused by scaling of 3/6 heat transfer surface.

Superior scale prevention performance:
Contains a high-performance polymer scale inhibitor, provides coolant superior high-temperature anti-scale energy, avoids the blockage of radiator caused by scaling, prolongs the service life of the engine cooling system.

6. Package:
This product is formulated coolant additive product, packages are available by 200liters drum, 1000liters IBC-TANKS, ISO-TANKS or made to order.

7. Storage & Handle:
The storage temperature at 7-40ºC can ensure the maximum activity of this product, it needs to use the goods within 12months after the production date, when no use pay attention to the package seal condition. Check if there is crystallization before use, if yes, please warm the package in the heating room to dissolve the crystallization (heat less than 60ºC), mix well then to use.

8. Coolant Production Method of Antifreeze Coolant Additive
The measured deionized water (NaNO2) was added to the stirred kettle, dissolved, then added ethylene glycol, stirred for 10 min. in the stirring state, the metering additive AC7040 was added to stir for 10 min. The pH value was detected by central control (taking the coolant at -35ºC as an example PH value = 8-9), the freezing point was detected by central control, and the finished product of coolant was obtained by adding defoamer and pigment after passing.
