AI Technical Summary
Existing rust-preventive oils have problems such as inorganic ash residue, interference with cooling rate and appearance quality during the quenching process, and cannot meet the high-temperature rust prevention requirements of precision quenched workpieces. In addition, existing cleaning solutions increase costs and environmental risks.
A combination of ashless long-chain organic carboxylic acids, ashless organic amine salts, ashless rust-preventive oil composite additives, copper corrosion inhibitors, and aluminum corrosion inhibitors, along with phenolic ester antioxidants and small-molecule hindered phenolic ashless antioxidants, is used to form a rust-preventive oil specifically for quenched workpieces, ensuring environmental friendliness and high-efficiency cleaning performance.
It achieves zero ash residue and does not interfere with the cooling rate, improves the brightness and rust prevention performance of quenched workpieces, reduces production costs and environmental risks, and is suitable for the rust prevention needs of multi-metal workpieces.
