A method for inhibiting or retarding the corrosion of metals in contact with water solutions containing lithium halide comprises introducing into the solution a crystal habit modifier and lithium molybdate.

A lubricant composition capable of preventing a rolling surface of a bearing from flaking owing to hydrogen embrittlement. The bearing is lubricated with the lubricant composition which is a lubricating oil or grease. The lubricant composition contains a molybdate and an organic acid salt. At least one molybdate is selected from sodium molybdate, potassium molybdate, and lithium molybdate. The organic acid salt is a sodium salt of an organic acid having one to 20 carbon atoms. The lubricant composition forms a film containing a molybdenum compound in addition to an iron oxide film on a worn surface of the bearing or on a fresh surface of an iron-based metal generated by wear. The bearing is used as a rolling bearing for use in electric parts and auxiliary machines of a vehicle. The bearing is also used as a bearing, for a motor, in which the lubricant composition is sealed.

The invention discloses a multifunctional concrete structure endurance protective agent as well as the preparation and application method thereof. The protective agent provided by the invention contains the following ingredients of: an organic / inorganic composite fluorosilicone-acrylate copolymer, lithium silicate, sodium silicate, lithium molybdate, sodium tetraborate, sal glauberi, 1,2-aminoazophenylene, nanometer titanium dioxide, anhydrous ethanol and water. The protective agent can penetrate inside concrete, wherein a densification ingredient can minimize internal holes and cracks to raise the compactness of concrete, and a rust-resistant ingredient can penetrate into concrete and be adsorbed on the surface of steel bar so as to passivate and protect the steel bar; the low-surface energy silicon fluoride ingredient can be solidified to form a cured film on the surface of concrete so as to endow the protective agent with the hydrophobic performance; a nanometer ingredient can endow the cured film layer with properties of resisting ultraviolet and ageing and improving the organic polymer performance as well as the self-cleaning performance. In addition, hydroxy generated from the hydrolysis of siloxane group can perform a condensation reaction with hydroxy on the surface of concrete to produce chemical bond, so as to raise the anchoring strength between the film and concrete and improve the interface combination. The protective agent provided by the invention can be widely applied in various concrete structure engineering protections to raise the service life of concrete.
