Abstract
The invention discloses a high-efficiency rust remover for medical instruments and a preparation method thereof. The efficient rust remover for the medical instruments is a water-based solution compounded by a surfactant, an acid, a cleaning assistant, a chelating agent and the like through reasonable formula design. The high-efficiency rust remover for the medical apparatus has the advantages of high rust removing and descaling speed, no damage to stainless steel apparatuses, simple production and environmental friendliness.
Description
Technical Field
The invention belongs to an efficient rust remover for medical instruments, and relates to a preparation method of the rust remover.
Background
In hospitals all over the world, various medical instruments are frequently used every day, particularly various surgical instruments including common surgical instruments, precise minimally invasive surgical instruments and the like are contacted with pollutants such as bloodstains and the like in the process of operation, and if the pollutants are not treated in time, the pollutants can easily accelerate the rusting and corrosion of the medical instruments, so that the instruments are out of order and cannot be normally used. The existing medical instruments are often high in price, in order to reduce the using cost of the instruments, the instruments need to be cleaned and maintained in time after being used, and rusty spots need to be removed in time when rusting is found, so that the situation that the rust expands to cause that the instruments cannot be repaired when being scrapped is avoided.
The prior hospitals usually use strong acid rust removers, which can effectively remove rust spots and rust stains, particularly large-area rust stains, but have serious corrosion to instruments, which is a contradiction. The existing medical apparatus is expensive, so the strong acid rust remover is not suitable for removing rust of the apparatus, but rather a milder rust remover should be selected. However, the mild rust remover has the disadvantages of long rust removing time, low efficiency and incomplete rust removal, and cannot meet the use requirements.
In order to overcome the problems of the prior rust remover for medical instruments, the invention develops an efficient rust remover and a preparation method thereof. The composite surface active agent is used, so that the surface energy of the instrument is effectively reduced, the using amount of an acid agent is reduced, the corrosivity of acid to the instrument is reduced, and the corrosion of the instrument is effectively protected by using the composite chelating agent and the corrosion inhibitor.
