Corrosion test fluid for testing internal corrosion of e.g. oil cooler, has coolant having zero to twenty percentage of weight, and component with product to degrade coolant, where fluid has specific values of glycollate ions or propionate

摘要

#CMT# #/CMT# The fluid has a coolant e.g. ethylene glycol and/or propyleneglycol, having 0 to 20 percentage of weight. A component has a product to degrade the coolant. A corrosion initiator component has corrosive ions in the fluid and accelerates internal corrosion of a heat exchanger made of aluminum or alloy of aluminum. The fluid has 100 and 1000 milligram per liter of glycollate ions or propionate, and has 100 and 500 milligram per liter of corrosive ions e.g. chloride ions, in the water. The fluid has 0 and 100 milligram per liter of oxalate. The fluid is liquid composed of 90 percentage of water. #CMT#USE : #/CMT# Corrosion test fluid for testing the internal corrosion of heat exchanger e.g. air radiator, oil cooler, overheating air exchanger and air-conditioning heat exchanger, of a motor vehicle, where the heat exchanger is located in an engine coolant loop or passenger compartment. #CMT#ADVANTAGE : #/CMT# The fluid reliably tests the internal corrosion related to real utilization of the heat exchanger of the motor vehicle in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a photography of surfaces and sections of a core of a heat exchanger obtained from corrosion test.
