The appearance of SAP has led to a revolution in the use and production of diapers. Because of their high water absorption and good water retention performance, modern disposable diapers bring convenience to mothers but also bring dry and comfortable babies.
As the raw material of diapers, SAP has many characteristics, such as absorption rate, absorption amount, absorption amount under pressure, and water retention.
Absorption rate: It shows the maximum absorption amount of polymer absorbent resin in a certain period of time. The general data is 1g in the first 30s,60s or 180s
The saline can be absorbed by macromolecule absorbent resin.
Absorption: It shows the maximum physiological salt water absorbed by 1g macromolecule absorbent resin.
Absorption under pressure (0.70pa): It shows the maximum absorption of 1g macromolecule absorbent resin under the pressure of 0.7pa. This is because
Babies spend most of their time sitting or lying down, and urine is often absorbed under pressure from the body. This test is designed to simulate
And to understand the absorption of absorbent resin under pressure.
Water retention: It shows that 1g polymer absorbent resin can retain the maximum amount of water after absorbing the maximum physiological salt water after 1400 revolutions of centrifugal treatment
The amount of salt processing water. It shows that the highly absorbent resin can really maintain a fixed physiological salinity.
Specific gravity and particle distribution: It shows the specific gravity of polymer absorbent resin and particle size and distribution.
These characteristics all have different contributions to the performance of diapers, so we do not think that a high number is necessarily a good product, but relatively speaking, water retention and absorption under pressure are more important.
