Problems solved by technology

[0004] Traditional chemical rust removal usually uses strong acid, which can chemically react with rust and metal oxides to form soluble salts, so as to achieve the purpose of rust removal, but at the same time, the acid can react with the base metal to release hydrogen. It will cause hydrogen embrittlement of the steel, cause the mechanical properties of the metal to decline, and affect the strength of the steel itself; at the same time, it is easy to form acid mist, which will affect the health of the operator and corrode the surrounding equipment and environment; and the cost is expensive, not suitable for hemodialysis machine fluid Road system derusting and cleaning

Description

technical field [0001] The invention relates to the technical field of use and maintenance of medical equipment, in particular to a rust remover for a liquid circuit system of a hemodialysis machine and a preparation method thereof. Background technique [0002] In recent years, the number of patients with kidney disease at home and abroad is increasing, and the mortality rate is also increasing. Hemodialysis is still the main treatment for advanced kidney disease and the main way for patients with advanced kidney disease to maintain their lives. It is to introduce the patient's blood and dialysate into the dialyzer in opposite directions at the same time, and flow through the two sides of the dialysis membrane respectively. The solute and water on both sides move across the membrane under the concentration and pressure gradient for material exchange, thereby purifying The role of blood. [0003] The hemodialysis machine is the equipment used for hemodialysis. For the hemod...
