Problems solved by technology

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 performance of absorbent materials used in sanitary napkins and sanitary products; later, people bought real human blood or used animal blood for testing, but real human blood and Animal blood is not easy to obtain, not only expensive but also easy to agglomerate and difficult to store
[0004] At present, the formula of a blood simulated liquid, that is, the standard liquid, is used to test the superabsorbent resin for women's sanitary products and sanitary napkins, which has been included in the national standard of "superabsorbent resin for sanitary napkins", but after research, The pH value of this standard solution is about 4 values ​​higher than the pH value of real women's menstrual blood, and the viscosity is about 7 values ​​higher than that of real blood. This results in that the value of the blood test product cannot be well approached when testing the product. Therefore, this solution is used The obtained test results cannot well reflect the blood-absorbing characteristics of sanitary products, and the inaccurate test results also lead to unstable absorption performance of sanitary napkins and superabsorbent resin products, which has negative impact on the production of upstream product materials and the quality of downstream products. certain influence

Abstract

The invention belongs to the technical field of blood simulation liquid, and relates to a preparation method of woman menstrual blood simulation liquid. The woman menstrual blood simulation liquid is prepared from the following raw materials of: third-level water, inorganic sodium salt, an acid-base regulator, a thickening agent, a simulation modifier, a simulation regulator, a preservative and haematochrome. According to the woman menstrual blood simulation liquid prepared by the method, the added simulation modifier is matched with other components in the simulation liquid through fractional precipitation and stirring, a product which is more excellent than an existing standard test liquid is obtained; compared with an existing standard liquid, the product is closer to the physical characteristics of human blood; compared with human and animal blood materials, the product has the advantages of being not prone to caking, easy to store, cheaper and the like; and the product has good guiding significance in measurement of absorption and permeability of sanitary napkins and high-absorptivity resin.
