The “marine life ball” is actually made of plastic. The reason why it can grow is: 1. Collagen absorbs water and expands in water. 2. It ruptures when it exceeds the expansion coefficient. 3. Releases new collagen. 4. Collagen absorbs water in water. Expansion 5. Exceeds the expansion coefficient and ruptures. 6. Everything disappears. There are two generations in total. Please pay attention: When you first bought it, there were several small balls. Once split, the little balls disappeared and new ones appeared. Finally, the sea life ball Neither ocean nor life
The scientific name for bubble beads is a super absorbent resin. newly developed type that contains strong hydrophilic groups and exhibits a certain degree of cross-linking functional polymer materials. These resins are insoluble in water and organic solvents. They can absorbhundreds, even thousands of times their own weight in water and are very water-retaining. Even if the water is under pressure, it will not be discharged.
For example, starch-grafted acrylates, highly substituted cross-linked carboxymethylcellulose, cross-linked hydroxyethylcellulose-grafted acrylamide polymer, etc., can generally absorb the equivalent of 100% of the volume of resin. humidity, the highest water absorption rate can reach more than 1,000 times. It is usually used as a medical material, such as diapers, sanitary napkins, etc., and is also used as a leak-proof material in industry.
Detailed information
Uses of super absorbent resin:
Water absorbent polymer resin is a non-toxic polymerization of networked polymers. It has strong water absorption properties.
1. Medical and health care: sanitary napkins, mattresseschanging pads, diapers, medical mattresses, absorbent paper, sustained-release medications, ointments, water bags, etc.
2. Agriculture and gardening: seed coating, seed treatment and seedling cultivation.
3. Industry: water-resistant expanding rubber, water-absorbing antifouling paint, anti-static paint, oil field water blocking and oil-water separation, optical cables
Resistant tape and cable paste , waiting for concrete maintenance.
4. Water absorbent for the food industry, preservative for fruits and vegetables.
