1 Overview Place the sample on the curved sample base lined with absorbent paper, and place the standard test liquid addition module on the absorbing area of the sample surface.
Under a certain pressure, the liquid filling device injects a certain volume of normal saline into the standard test liquid addition module, and the automatic timing device records the time from the start of adding liquid to the sample completely absorbing the normal saline
.
Each sample was added twice, and the absorption speed of the sample was represented by the two absorption times respectively
.
After the second liquid addition is completed, take out the standard test liquid addition module, place a certain number of layers of absorbent paper on the surface of the sample, and then put it into the standard test pressurization module, and pressurize it under a certain pressure for a specified time to test.
The mass increase of the absorbent paper on the top of the sample represents the rewet amount of the small sample, and the mass increase of the absorbent paper at the bottom of the sample represents the leakage of the sample
