Embodiment 1
[0029] Select 15% engine oil, 10% fatty acid, 10% triethanolamine, 1% 105 cleaning agent, 1% ethylene glycol fungicide, 4% silicone oil defoamer, and 59% pure water according to the ratio; Add fatty acid and silicone oil components into the container, add pure water to dissolve, then add triethanolamine, emulsifier, bactericide, defoamer in sequence according to the proportion, stir to dissolve and make to volume.
[0030] The 12.9-grade high-strength bolts of the DCi11 engine are phosphating, immersed in the stabilizer, and then taken out to dry. Through the treatment of the friction coefficient stabilizer in this embodiment, the friction coefficient (mean value) is reduced from the original 0.12 to 0.075, and the dispersion is reduced from 0.02 to 0.01, which is strictly controlled within the range of 0.075±0.015, achieving a good friction control Coefficient and anti-corrosion effect.
Embodiment 2
[0032] Select spindle oil 20%, fatty acid 12%, triethanolamine 10%, op-10 emulsifier 2%, fungicide 0.5%, silicone oil 3%, purified water 52.5% according to the ratio; Put the components into the container, add pure water to dissolve, then add triethanolamine, emulsifier, bactericide, and defoamer in sequence according to the proportion, stir to dissolve and constant volume.
[0033] The 12.9-grade high-strength bolts of the DCi11 engine are phosphating, immersed in the stabilizer, and then taken out to dry. Through the treatment of the friction coefficient stabilizer in this embodiment, the friction coefficient (mean value) is reduced from the original 0.12 to 0.075, and the dispersion is reduced from 0.02 to 0.01, which is strictly controlled within the range of 0.075±0.015, achieving a good friction control Coefficient and anti-corrosion effect.
Embodiment 3
[0035] According to the ratio, select engine oil 19.5%, fatty acid 6%, triethanolamine 9%, Tween emulsifier 1%, ethylene glycol fungicide 0.5%, silicone oil 5%, purified water 60%; Add the silicone oil component into the container, add pure water to dissolve, then add triethanolamine, emulsifier, bactericide, and defoamer in sequence according to the proportion, stir to dissolve and constant volume.
[0036] The 12.9-grade high-strength bolts of the DCi11 engine are phosphating, immersed in the stabilizer, and then taken out to dry. Through the treatment of the friction coefficient stabilizer in this embodiment, the friction coefficient (mean value) is reduced from the original 0.12 to 0.075, and the dispersion is reduced from 0.02 to 0.01, which is strictly controlled within the range of 0.075±0.015, achieving a good friction control Coefficient and anti-corrosion effect.
