Embodiment

[0052] A. Bubble level test

[0053] Since lubricants are to be used in automatic cleaning machines, it is preferable to choose a formulation with low foaming ingredients. Use the foam level test (STM 100) to carry out the base oil screening test.

[0054] 1) Dilute 5% oil solution with distilled water at 25°C or 60°C at 1:200;

[0055] 2) Put the diluted solution into the beaker and record the initial height of the solution (record the volume value marked in ml as the height, and the appropriate final volume is 500 ml);

[0056] 3) Mix the solution in a blender (Philips Comfort) at high speed for 20 seconds;

[0057] 4) Stop stirring and record the height of the solution foam at 0, 10, 20 and 30 seconds respectively;

[0058] 5) Calculate the height of the foam:

[0059] Foam height = total height at the time of recording-initial solution height.

[0060] The preferred base oil is that the foam height is less than 50ml in 20 seconds.

[0061] Table 1 shows the base oils evaluated in the p...

Abstract

The present invention provides a rust inhibiting lubricant. Based on the total weight of the rust inhibiting lubricant, the rust inhibiting lubricant comprises: (a) from 5% to 45% of base oil, wherein the base oil is one or more substances selected from the following group: polyalkelene glycol, fatty glyceride and propanetriol; (b) from 0.1% to 15% of corrosion inhibitor, wherein the corrosion inhibitor may be one or more substances selected from the following group: organic poly(carboxylic acid), organic polycarboxylate salt and alkyl amine; (c) from 0.05% to 10% of anti-corrosion agent, wherein the anti-corrosion agent may be one or more substances selected from the following group: benzoic acid anti-corrosion agents and isothiazoline anti-corrosion agents; and (d) from 30% to 90% of water.

Description

Technical field [0001] The present disclosure relates to an anti-rust lubricant, in particular to an anti-rust lubricant for medical devices, and also relates to a method for lubricating medical devices. Background technique [0002] In the daily operation of the hospital, stainless steel or other metal medical instruments, such as surgical scissors, surgical curved discs, and stainless steel tweezers, are used extensively. The contact of these metal medical devices with electrolytes such as medical blood stains, chlorine- and iodine-containing disinfectants, and physiological saline will accelerate the corrosion of the devices, resulting in rusting of the devices and joint failure. These problems increase the operating costs of the hospital and increase the risk of infection for patients. In order to extend the service life of metal medical equipment and reduce hospital expenditures, many hospitals use strong acid rust removers to remove rust from rusty equipment, thereby achie...
