Example Embodiment

[0051] Example

[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 ev...

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...
