防止内燃机车缸套穴蚀的新型冷却液

A New Coolant for Preventing the Cylinder of Diesel Locomotive from Cavitation

原用重铬酸钾、NL防锈油防止内燃机车的缸套、冷却系统的腐蚀,但毒性大,效果不佳。现找到了以硼砂、亚硝酸钠、苯骈三氮唑和硝酸钠等组合而成的冷却液,有效地防止了内燃机车缸套和冷却系统的穴蚀。

The potassium dichromate and NL antirust oil which were used to prevent the cylinder and cooling system of diesel locomotive from corrosion are not good enough and have toxicity. The new coolant composed of borax, sodium nitrite, benzotriazote, sodium nitrate et al. can prevent effectively the cylinder and the cooling system from cavitation.
