Compound rapid medical apparatus rust remover

Abstract

The invention discloses a medical apparatus rust remover, and belongs to the technical field of fine chemical engineering. The rust remover is characterized in that the rust remover includes, by mass, 5-30% of an inorganic acid component, 0.5-5% of an organic acid component, 0.2-1% of a surfactant component, 0.01-0.05% of a perfume component, 0.10-0.20% of a solvent component I, and the balance solvent component II. The rust remover is a colorless, transparent, mild and weakly acidic liquid, having a pH value of 2-3, has stable performances and a mint smell, is suitable for removing floating rust, rust deposits and rusty spots of stainless steel, carbon steel, cast iron, metals of copper and the like, and alloy material apparatuses of the metals, and does not damage or corrode the materials of the above apparatuses. The components contained in the rust remover are weakly toxic to aquatic organisms, and the rust remover can be directly discharged without environmental harms.

Description

1. Technical field [0001] The invention relates to a rust remover, in particular to a rust remover for medical instruments, and belongs to the technical field of fine chemicals. 2. Technical background [0002] During the long-term placement of medical devices in the air, the surface of the medical device undergoes a slow oxidation reaction with the oxygen in the air to form rust and rust spots, resulting in a decrease in the surface finish and flexibility of the shaft joints of the device, and it is easy to breed bacteria in the rust and rust spots , causing the sterilization effect to be substandard. If the device is scrapped without derusting the device, a large amount of metal waste will be generated and the cost of device renewal will be increased. The rust removers for medical devices currently on the market often have poor rust removal effects during use, take a long time, and the rust removal is labor-intensive and time-consuming. Some rust removers have a pungent o...
