What Are Diaper Raw Materials?

The birth of each baby will bring a lot of joy to the family. Babies are an important part of the family, so every household item chosen for the baby must be strictly screened. The baby's diapers also need to be strictly screened. There are many types of diapers on the market. If the selection is not good, it will bring great harm to the baby's little ass. So, what are the diaper raw materials?

1.What are diaper raw materials

Diapers are commonly used daily necessities for babies, and are collectively referred to as diapers, diapers, and pull-up pants. Dry diapers can keep babies sleeping through the night, and are commonly known as "diapers" due to their strong water absorption.

Among them, super absorbent resin (referred to as polymer SAP) is an excellent material for making baby diapers. It is made of starch and acrylate as the main raw materials; the outstanding feature is that the water absorption and storage capacity are surprisingly large.

2. diaper raw materials basic introduction

Super absorbent resin (referred to as polymer SAP) is used to manufacture baby diaper raw materials, which is made of starch and acrylate as the main 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. Therefore, children do not need to worry about wetting their pants when they pee.

3.The origin of diaper raw materials

In 1961, the Soviet astronaut Gagarin felt a sudden urgency when he stepped into the launch capsule, so he had to come down and urinate along the tube of the spacesuit; in the same year, the American astronaut Shepard, who was unable to launch in the spacecraft, also suffered In case of urgency, the commander ordered him to pee in the space suit.

In the 1980s, the "father of space suits" Chinese Tang Xinyuan, in order to solve the urination problem of astronauts, improved the space suit, added a polymer absorber, and invented a diaper that can absorb 1400 ml of water. Urinating is no longer a problem for astronauts. . The technology was later transferred to civilian use, which is the "diapers" used by thousands of households now.

4. diaper raw materials--super absorbent resin

Super absorbent resin is a newly developed functional polymer material containing strong hydrophilic groups and 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 USDA Research Center first developed a superabsorbent resin, and various types of superabsorbent resins have appeared since then. 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, so even pressurized water will not be squeezed out, thus attracting attention from 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.

Features

A. High water absorption: It can absorb hundreds or thousands of times of its own weight in deionized water.

B. High water absorption rate: Each gram of superabsorbent resin can absorb hundreds of grams of non-ionized water within 30 seconds.

C. High water retention: The gel after water absorption is not easy to squeeze out of water under external pressure.

D. High expansion: The volume of the superabsorbent resin gel will expand hundreds of times after absorbing water.

E. 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.
