kaliumpolyacrylaat

Kaliumpolyacrylaat, commonly known as potassium polyacrylate, is a synthetic polymer classified as a superabsorbent polymer (SAP). It is primarily composed of potassium salts of polyacrylic acid, characterized by its remarkable ability to absorb and retain large quantities of aqueous solutions relative to its mass.

This polymer is widely utilized in various applications due to its high absorbency, including in personal hygiene products such as adult incontinence pads, baby diapers, and feminine hygiene products. Its capability to absorb significant amounts of liquid helps in maintaining dryness and preventing leakage. Additionally, potassium polyacrylate is used in agriculture as a water-retaining agent in soil, promoting plant growth in arid conditions. It is also incorporated into soil conditioners and seamless concrete mixes due to its moisture-retention properties.

Kaliumpolyacrylaat is produced through the polymerization of acrylic acid potassium salts, often initiated by free-radical mechanisms. The resulting polymer is a white granular or powdery substance that is chemically inert and non-toxic when handled properly, although direct ingestion or inhalation may pose health risks.

Environmental considerations include its resistance to biodegradation, which raises concerns about its accumulation in ecosystems if not managed responsibly. Nevertheless, its widespread use remains crucial in water conservation and hygiene-related sectors.

Overall, kaliumpolyacrylaat’s unique water-absorption properties make it a valuable material across multiple industries, balancing utility with considerations for environmental impact.
