Lubricants & Metalworking Fluids Industry

Process Nodes

Key stages of the industry process and the chemicals involved

01

Thickening & Saponification

Lithium hydroxide saponifies with 12-hydroxystearic acid to make lithium thickeners; base equivalent and moisture directly affect soap structure consistency.

Lithium Hydroxide 12-Hydroxystearic Acid

02

Rust Prevention & Antioxidation

Sodium nitrate and nitrite provide rust-inhibiting components for metalworking fluids and rust preventives, with precise nitrate and chloride control.

Sodium Nitrate → Sodium Nitrite →

03

Water-based Fluids

Boric acid and borax provide rust prevention and pH buffering in semi-synthetic cutting fluids; triethanolamine adjusts alkaline reserve of emulsion systems.

Boric Acid → Triethanolamine

FAQ

What role does boric acid play in grease?

Boric acid is used in the borating step of complex lithium grease, working with lithium hydroxide and 12-HSA to form complex soap fibers, improving drop point and shear stability.

What are the moisture and chloride specs of sodium nitrate?

Standard: moisture ≤ 0.5%, chlorides (as Cl) ≤ 0.1%; stricter internal control specs can be provided per formulation requirements.

Can you send samples for small-batch trials?

Yes, 1-5kg samples are dispatched within 24 hours with COA and recommended dosage notes.

Any special requirements for exporting metalworking fluid raw materials?

Sodium nitrite and similar items are regulated; export requires DG packing certificates and destination permits, with full document support from us.
