A basic introduction to diapers

Superabsorbent resin (SAP for short) is an excellent material for making baby diapers, which is made of starch and acrylic salt as the main raw materials. The outstanding feature of "diaper" is that it absorbs water and stores a surprisingly large amount of water. The absorption of normal saline is 40 to 60 times its own weight, and the absorption of pure water is 50 to 100 times its own weight. Therefore, children do not have to worry about wetting their pants, and the urine that flows out will be all "drunk" by it, commonly known as "diaper".
