Abstract

The invention belongs to the technical field of blood simulation liquid, and particularly relates to woman menstruation simulation liquid and a preparation method thereof. The woman menstruation simulation liquid is prepared from three-level water, inorganic sodium salt, acidifying or alkalizing agents, thickening agents, simulation modifying agents, simulation regulating agents, preservatives and red pigments. The woman menstruation simulation liquid is scientific and reasonable in formula, and the simulation modifying agents are added and matched with other components in the simulation liquid to obtain a product better than existing standard testing liquid. Compared with existing standard liquid, the woman menstruation simulation liquid is closer to the physical property of human blood. Compared with human and animal blood materials, the woman menstruation simulation liquid has the advantages of difficulty in caking, easiness in storage, lower price and the like and has excellent guiding significance for testing absorbing and penetrating performances of sanitary towels and high-absorptive resin.

Description

[0001] (1) Technical field [0002] The invention belongs to the technical field of blood simulation fluid, in particular to a women's menstrual blood simulation fluid and a preparation method thereof. [0003] (2) Background technology [0004] In recent years, high-absorbent resin materials for sanitary napkins have been produced through technical research and development of high-molecular absorbent resins, the raw materials for sanitary products. In the past, the penetration and absorption performance of sanitary napkins and absorbent materials for sanitary napkins were generally tested by physiological saline and distilled water, but the physical properties of real women's menstrual blood and distilled water and normal saline are quite different, and with the continuous improvement of detection methods, Simply using normal saline and distilled water can no longer meet the needs of penetration and absorption performance tests, and cannot reflect the blood absorption performa...
