Antifreeze with ethylene glycol as coolant acidifies overtime and oxidizes when exposed to air and heat. Upon oxidation, glycol breaks down into organic acids such as glycolic, glyoxalic, formic, carbonic and oxalic acid. These are corrosive and chemically attack the materials of construction corroding, cracking the process pipelines.
The major problems faced by automobiles and heavy-duty diesel engines
are corrosion, pitting, scaling and acidification.
Corrosion
Corrosion affects all metal parts with the corroded products circulating
freely in the cooling system later causing erosional damage, and channel blocking.
This leads to system failure and increased system downtime. The second
being decrease in efficiency owing to loss in heat transferring properties.
Mechanical vibrations cause pressure changes in the coolant forming gas
bubbles. This consistent air pocket formation and breakdown along surfaces can
be repetitive and violent enough to corrode the underlining metal resulting in pitting
or cavitation.
Scaling or deposition
With increase in temperatures, the dissolved salts in water of the
coolant becomes less soluble and precipitate on the pipeline surfaces. Hard
water scales can block a cooling system’s ability to transfer heat resulting in
overheating.
System Acidification
And, finally coolants acidify/ ferment because of the degradation of liquid
catalyst and burning gasses entering the system, which can harm cooling
framework.
Antifreeze with Ethylene Glycol as Coolant from Chemtex Speciality ltd.
Glycol is a water-miscible antifreeze liquid frequently used in heat
transfer and cooling applications. Antifreeze with ethylene glycol as coolant
primarily functions as drawing away heat, and allowing the engine to operate
efficiently, with lesser malfunctions and damages to its parts.
Chemtex coolants are pre-inhibited with corrosion inhibitors, foam
control, etc. If not properly inhibited, the fluid gets very corrosive. These
organic acids then chemically attack and corrodes the system metal, causing
pitting, pinhole and stress cracking corrosion.
Corrosion Inhibited
Ethylene Glycol-based antifreeze is used as an industrial / engine coolant.
The inhibitor package is designed to protect brass, copper, steel, cast
iron, aluminum alloys, and other components such as rubber hoses, rubber seals,
plastic components, etc., commonly found in the cooling and heating systems and
in the engine and radiator.
Meets ASTM D1384, ASTM D4340, ASTM D2570, ASTM D2809 Standards.
Chemtex Speciality Ltd is one of the leading manufacturers of Ethylene Glycol
based Coolant Antifreeze liquid to meet the desired end uses. It is one of the
extremely useful and important organic compounds for running your vehicle
smoothly and maintaining the temperature of the engine all year round. Chemtex
Car Coolant comes in two variants:
·
A conventional blend NAP-free tropical car coolant
·
Extended-life coolant (ELC) with longer life &
protection
