Embodiment

[0052] A. Foam level test

[0053] Since the lubricant is to be used in automatic washing machines, it is preferred to select a formulation with a low foam content. Screening tests for base oils were performed using the Foam Level Test (STM 100).

[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 a beaker and record the initial height of the solution (the volume value marked in ml is recorded as the height, and the suitable final volume is 500ml);

[0056] 3) Mix the solution at high speed in a blender (Philips Comfort) 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 foam height:

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

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

[0061] Table 1 shows the base oils evaluat...

Abstract

The invention provides a rustproof lubricating agent. Based on the total weight of the rustproof lubricating agent, the rustproof lubricating agent comprises the following components: (a) 5%-45% of base oil, wherein the base oil is one or more selected from polyaleneglycol, fatty acid glyceride and propanetriol; (b) 0.1%-15% of corrosion inhibitor, wherein the corrosion inhibitor can be one or more selected from organic polycarboxylic acid, organic polycarboxylate and alkylamine; (c) 0.05%-10% of preservative, wherein the preservative can be one or more selected from benzoic acid type preservative and isothiazolizone type preservative; and (d) 30%-90% of water.

Description

technical field [0001] The disclosure relates to an antirust lubricant, in particular to an antirust lubricant for medical equipment, and also to a method for lubricating medical equipment. Background technique [0002] During the daily operation of the hospital, a large number of stainless steel or other metal medical instruments are used, such as surgical scissors, surgical curved plates, stainless steel tweezers, etc. The contact of these metal medical instruments with electrolytes such as medical blood stains, chlorine- and iodine-containing disinfectants, and normal saline will accelerate the corrosion of the instruments, resulting in instrument rust and joint failure. These issues add to hospital operating costs and raise the risk of infection for patients. In order to prolong the service life of metal medical instruments and reduce hospital expenditure costs, many hospitals use strong acid rust removers to derust rusted instruments so as to realize repeated use. How...
