Problems solved by technology

Although the strong acid system has obvious rust removal effect, the liquid strong acid is inconvenient to transport and store, and it has high corrosiveness to the metal products themselves. The use of this kind of rust remover products is also obvious in rust removal and rust removal, causing secondary damage to equipment ; and using strong acid as raw material, in the process of preparation and use of rust remover, it is not only easy to produce acid mist, but also easy to cause harm to human body and environment; and there are special requirements in raw material procurement and logistics transportation, which increases transportation costs

Abstract

The invention belongs to the technical field of metal surface minimally-invasive rust removal and scale removal, and provides a medical efficient rust removal and scale removal agent and a preparation method thereof. The rust removal and scale removal agent is prepared from raw materials including a surfactant, organic acid, a chelating agent, an anti-rust brightening agent, a permeation solubilizer and water; according to the rust removal and scale removal agent, a strong acid component in a traditional rust removal agent is replaced with a food acidulant (food-grade natural organic acid), the rust removal and scale removal agent is completely corrosion-free to a medical instrument, a layer of nanoscale protective film is formed on the surface of the medical instrument, metal can be kept rustless for a long time after the rust removal and scale removal agent is used, the single rust removal function and the single scale removal function are combined, operation steps and links are reduced, and the rust removal and scale removal agent is convenient to use, phosphorus-free and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of minimally invasive rust and scale removal on metal surfaces, and in particular relates to a medical high-efficiency rust and scale remover and a preparation method thereof. Background technique [0002] At present, the cleaning and maintenance of medical equipment in the world is getting more and more attention from major medical equipment. There are various types of medical equipment, different shapes and high reuse rate. Most of them are made of metal materials. Improper cleaning and maintenance may cause the equipment to rust. , and medical equipment is corroded by blood stains, organic pollutants, mucopolysaccharides, etc., forming rust spots and dirt spots. If they are not cleaned and removed, there will be a greater risk of surgery. Proper cleaning, maintenance and disinfection can ensure that medical devices, especially surgical medical devices, perform their intended functions and prolong their se...
