What is the Sanitary Napkin Absorbency Multiplier Tester

Absorbent multiplier is the ratio of the mass increased by absorption to the pre-absorption mass, which reflects the total amount of water absorbed by the product after a period of immersion, and the larger the absorbent multiplier is, the stronger the absorption capacity. Enhanced water absorption primarily results from polymer resin additives in the absorbent layer, the excessive pursuit of high water absorption rate will increase the production cost, and may also cause a waste of resources. Sanitary napkin manufacturers can also control the cost according to the test data when testing whether the product absorbency index is qualified or not, so as not to cause cost waste.

Advantages of the Sanitary Napkin Water Absorption Rate Tester

• Automated testing: GESTER's sanitary napkin water absorption multiplier tester GT-CN20, the experimental process is fully automated to complete, eliminating the need for manual weighing and avoiding perceived errors.
• Key parameters including absorption time, dwell time and test speed are fully adjustable, ensuring broad application flexibility.
• Easy to operate: the Water Absorption Rate Tester  has a friendly user interface and operation flow, operators can easily complete tests by following standard procedures.
• Wide applicability: The sanitary napkin water absorption multiplier tester GT-CN20 is not only suitable for the water absorption multiplier test of sanitary napkins and sanitary pads, but also can be used for the saturation absorption test of absorbent materials such as adult diapers.

How to operate the sanitary napkin water absorption rate tester GT-CN20

Acceptance

• Accessories display: Clamps, small clamps, 100g weight, fuse, software USB stick, USB cable, water pipe.

• Add water to the sink, add water to half of this piece (adjust according to the test demand), stop adding water.
• Turn on the power.
• Enter the main interface, including “Set” setup interface, “Work” test interface, “Cali” calibration interface, “Repo” report interface.

• “Infiltration time": The sample is immersed in water for 60s.
• “Hanging time": The sample leaves the water surface and hangs for 90s.
• “Test speed":The speed of rising and falling of the instrument, the fastest running speed is 900mm/min.
• “Down Height": The height of the sample falling into the water during the testing process is set (the falling height of 385mm has been set in the factory and does not need to be modified).
• “Tank temp": Set the temperature of the tank (standard 23℃).
• Press “OK” to confirm the completion of the setting. (Machine can be automatically switched to the test interface.)

• To prepare for the test, first click on the “Heat” button, and after the temperature has stabilised,
• click “Zero” single zero key or “ZERO” all zero key to zero the weight of 5 stations.
• Sample installation: Take down the fixture, press and hold the clamp to hang it up, two small clamps clip the sample, sample installation is complete.
• Then current weight is displayed, after stable, click “Run” start button.
• The instrument lifting platform will automatically descend to immerse the sample in the water, after descending into place, the timer will start for 60s.
• When the immersion is completed, the lifting platform will automatically lift the sample and completely remove it from the water surface. After lifting, it decouples itself and the sample is suspended vertically for 90s.

• After the test is completed, it displays 5 stations to weigh the mass before water absorption and the mass after water absorption, calculate the water absorption multiplier, and take the average value as the measurement result.
• When the test is finished, remove the fixture, dismantle the tested specimen, wipe the fixture with a clean cloth and prepare for the next test.
• The instrument test water tank should be cleaned regularly and contaminated water should be drained.
• When the instrument is not in operation for a long period of time, drain the water inside the test sink and wipe the water stains dry.
