The Diaper Absorption Rate Testing Machine is a specialized laboratory device used to evaluate how quickly diapers, sanitary napkins, and feminine pads absorb liquid. It measures the absorption speed of the product’s absorbent layer under standardized conditions, providing objective data on performance and ensuring compliance with quality standards.This machine is used to measure the absorption rate of diapers, sanitary napkins, and feminine pads, reflecting whether the absorbent layer in these products absorbs liquid in a timely manner. It complies with standards such as GB/T 8939-2018.
(1)GB/T 8939-2018
(2)GB/T 39391-2020
The Diaper Absorption Rate Testing Machine is used to evaluate the liquid absorption performance of diapers, sanitary pads, and other absorbent hygiene products. It measures parameters such as absorption capacity, absorption speed, and distribution efficiency under controlled conditions, providing critical data for product quality control, research and development, and compliance with industry standards.
The sanitary napkin is adhered to the curved sample holder of the absorption rate testing machine. A standard test module is placed on the absorption area of the sample surface. The automatic liquid dispensing device adds a specified volume of standard synthetic test fluid into the standard test module. A timer records the time it takes for the sanitary napkin to completely absorb the standard synthetic fluid, indicating its absorption rate.
