Agent antifoam performance is strong about 10 times.
By reasonable disposition corrosion inhibiter, defoamer, dispersant, between the nanoclay and other composition of modification
Effective compatibility, it is possible to promote antiseptic property, be greatly prolonged the service life of coolant.The successful development of this coolant, it is possible to
Efficiently solve cooling system etching problem, and be prevented from the erosion of rubber parts, effectively protect rubber seal, have notable
Economic benefit.
The invention has the beneficial effects as follows, compared with prior art:
Coolant of the present invention, environmental protection, cooling are good, by the synergism between each composition, improve the group of coolant
Knitting structural behaviour, the composition improving coolant is constituted, and improves coolant each side combination property；Coolant of the present invention, has anti-
Freeze, boiling protection, anticorrosion, effect of good antiscale property, heat transfer is fast, and good cooling results reduces the harm to environment and human body, deposits
Putting period will not produce by gel, does not have corrosion inhibiter and separates out, has long-lasting, and this product manufacture process is simple, used by set
Standby few, processing ease, required energy resource consumption is low, and production cost is low, it is easy to industrial-scale production, has the highest popularization and application
It is worth, there is good market prospect.
