Diapers are commonly used daily necessities for babies, and are a collective name for diapers, diapers, and pull-up pants. Because of its high water absorption, dry diapers can keep babies sleeping through the night.
Baby Diaper Raw Material SAP
Super absorbent polymer (referred to as polymer SAP) is an excellent material for making baby diapers. It is made of starch and acrylate as the main baby raw materials. The outstanding feature of “diapers” is the amazingly large amount of water absorption and storage. Its absorption of physiological saline is 40 to 60 times its own weight, and its absorption of pure water is 50 to 100 times its own weight. So children don’t have to worry about wetting their pants when they pee, and all the urine that flows out will be absorbed by it.
The scientific name of the water absorption/water locking factor is polymer water-absorbing resin, commonly known as water locking beads. It is a new type of polymer material.Baby diaper raw material sap can absorb hundreds to thousands of times its own weight in water, non-toxic, harmless and pollution-free. The super absorbent polymer has a strong water absorption capacity and high water retention capacity, and the high molecular weight polymer obtained by the polymerization of acrylic acid → high water retention capacity, and the balance of the absorption capacity under high load. The water absorbed by the polymer cannot be extruded by simple physical methods, and can repeatedly release and absorb water. The water absorption factor swells after absorbing water, and the touch is Q-bounce. This is because it swells after absorbing water from hundreds to thousands of times its own weight. However, the water it absorbs cannot be squeezed out by simple physical methods.

Baby diaper raw material SAP has led to a revolution in the use and production of diapers. In the past two decades, it has developed rapidly and has been widely used in disposable sanitary products, agricultural fields, optical cable industry and waterproof industry. Disposable hygiene products are the main and relatively mature application areas of polymer water-absorbent resins, accounting for about 70%-80% of the total amount of polymer water-absorbent resins, including baby care hygiene products, women’s care hygiene products and “incontinence hygiene” products. Baby diaper raw material SAPhigh water absorption and good water-locking properties bring convenience to millions of mothers, but also bring dryness and comfort to babies, and can prevent the reproduction of various bacteria. The application of macromolecule determines the quality of diapers, and the absorption capacity is large. Even a thin sheet has 7 times higher water absorption than ordinary thickened fluff pulp diapers.
Baby diaper raw material SAP is a newly developed functional polymer material that contains strong hydrophilic groups and has a certain degree of cross-linking. The adsorption materials used in the past, such as paper, cotton, linen, etc., have a water absorption capacity of only 15 to 40 times their own weight (referring to deionized water, the same below), and the water retention capacity is also quite poor. In the mid-1970s, the research center of the United States Department of Agriculture first developed a superabsorbent resin, and then various types of superabsorbent resins appeared one after another. These resins are insoluble in water and in organic solvents, can absorb hundreds to thousands of times of their own weight in water, and have strong water retention, even if pressurized water will not be squeezed out, thus arousing the attention of countries all over the world . The industrial production capacity of superabsorbent resins is continuously expanding, and it is widely used in medical and health care, building materials, environmental protection, agriculture, forestry and food industries.
The Properties Of SAP For Baby Diaper Raw Material
1. High water absorption: It can absorb hundreds or thousands of times of its own weight in deionized water.
2. High water absorption rate: Each gram of superabsorbent resin can absorb hundreds of grams of non-ionized water within 30 seconds.
3. High water retention: The gel after water absorption is not easy to squeeze out of water under external pressure.
4. High expansion: The volume of the superabsorbent resin gel will expand hundreds of times after absorbing water.
5. Ammonia absorption: Low cross-linked polyacrylate type super absorbent resin contains carboxyl anions in its molecular structure. which can be absorbed when it encounters ammonia, and has obvious deodorizing effect.
