| 摘要 |
An inhibitory composition for protection cooling systems of internal combustion engines from corrosive damage, cavitation and scale formation contains product of interaction alkanolamine, orthophosphoric acid and glycerol, sodium molybdate, sodium borate, benzotryazol, 4,4-dihydroxyphenyltrimethyl-2-sulfonate, sodium silicate, oxyethylidenediphosphonic acid and water. This composition allows to improve the protective properties from corrosive and mechanical damages during alternating and static loads, to increase the equipment longevity by forming an double electrical layer with a minimal charge, to increase antiscale properties, to exclude the possibility of slagformation and sedimentation on metal surfaces of cooling channels details. |
