How long does SAP take to degrade
SAP (super absorbent resin) is a highly absorbent polymer that can be used for drought resistance and water retention in crops, gardens, and lawns (potassium polyacrylate). It can also be used in sanitary napkins, diapers, urine pads, ice packs and other sanitary products (sodium polyacrylate).
SAP is an environmentally friendly, harmless, and degradable new material polymer. Due to its various applications in agricultural scenarios, how long does SAP degrade after use and how long does it need to be reused have always been issues of concern to customers.
Degradation time of SAP
The degradation time of SAP varies depending on many factors, including the type of SAP, environmental conditions (such as temperature, humidity, light, type and number of microorganisms, etc.), the chemical structure of SAP, and whether it has been modified. Under normal conditions of use, SAP can maintain its water absorption performance for a long time without obvious decomposition or degradation. However, under certain conditions, such as high temperature, high humidity, or the action of microorganisms, SAP may gradually decompose.
However, it is difficult to give a definite answer to the degradation time of SAP because it is affected by the above factors. Generally speaking, the degradation of SAP in the natural environment may take a long time, ranging from several months to several years, depending on the above conditions.
Differences and degradation time between agricultural SAP (potassium polyacrylate) and sanitary SAP (sodium polyacrylate)
Difference:
Agricultural SAP (potassium polyacrylate) and sanitary SAP (sodium polyacrylate) differ in chemical composition, containing potassium ions and sodium ions respectively. This difference may lead to different performance in different applications.
Potassium polyacrylate is commonly used in agriculture as a soil improvement and plant growth promoter because it can provide the potassium required by plants. Sodium polyacrylate is widely used in sanitary products (such as diapers, sanitary napkins) due to its excellent water absorption properties.
Degradation time:
The degradation time of both agricultural SAP and sanitary SAP is affected by the above factors. Therefore, it is impossible to simply judge whether the degradation time of the two is the same.
In general, if the two are compared under the same environmental conditions and without special modification, their degradation time may not be much different. However, if the specific conditions of use and modification in different applications are taken into account, the degradation time may be different.
