摘要:
Compositions for inhibiting mineral scale and the corrosion of metals particularly the cavitation corrosion of aluminum in the presence of aqueous liquids are disclosed. The combination of a water-soluble phosphate with at least one of a water-soluble molybdate, tungstate, or selenate is disclosed as providing a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids.

摘要:
The present invention provides an antifreeze/coolant additive comprising polymeric polycarboxylates which prevents hard water precipitants and scale formation, is soluble in alcohol and alcohol/water mixtures, is compatible with other commonly used antifreeze/coolant components, does not corrode or damage automotive cooling systems and is effective at relatively low concentrations.
摘要:
Cooling system cleaning solutions containing an EDTA salt, a polyhydroxy mono- or dicarboxylic sugar acid, and a soluble nitrate salt are effective in removing scale, corrosion, and solder bloom from cooling systems.

摘要:
The present invention provides aqueous concentrated corrosion inhibition formulations suitable for addition to depleted antifreeze/coolant compositions or corrosive water that use a mixture of polymeric polycarboxylates, azoles, nitrate salts, phosphates, stabilized silicates and transition metal compounds which reduces the corrosion rate and is effective at relatively low concentrations. The formulations are particularly suitable for automotive applications.
