Problems solved by technology

[0005] 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 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 operators and corrode the surrounding equipment and environment; and it is expensive, not suitable for hemodialysis machine fluid Road system derusting and cleaning

Abstract

The invention discloses a preparation method of a rust remover for a liquid path system of a hemodialysis machine. The preparation method comprises the following steps that 30-40 parts by weight of copolymers based on itaconic acid, 10-15 parts by weight of water-soluble benzotriazole, 5-10 parts by weight of triethanolamine, 10-15 parts by weight of lauryl polyoxyethylene sulfonyl succinate disodium, 5-10 parts by weight of vinegar and 400-500 parts by weight of deionized water are taken, the weighted copolymers based on the itaconic acid, water-soluble benzotriazole, triethanolamine, laurylpolyoxyethylene sulfonyl succinate disodium and vinegar are added into the deionized water, uniform mixing is conducted after the materials are dissolved, and the rust remover is obtained. The rust remover prepared through the preparation method of the rust remover for the liquid path system of the hemodialysis machine is low in production cost, stable in performance, high in dust removing efficiency, good in rust removing effect, safe to use and environmentally friendly.

Description

[0001] This invention is a divisional application of the Chinese patent "A rust remover for the fluid system of a hemodialysis machine and its preparation method". The application date is October 31, 2018, and the application number is 201811290728.7. technical field [0002] 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 [0003] 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. T...
