Introduction:
   The super water-absorbing polymer resin used in agriculture and forestry is commonly known as "water-retaining agent". It is a new type of functional polymer material. This type of substance contains a large number of strong water-absorbing groups and has a specific structure. It can produce high-permeability associations in the resin. Use and absorb water through its mesh structure. It can absorb and maintain pure water hundreds of times its own weight, and the water stored in the water-retaining agent can be directly absorbed by the roots of various crops, fruit trees, vegetables, flowers, trees, etc. This also makes the plant's drought resistance ability good Improved, this characteristic determines the wide application prospects of water-retaining agents in agriculture and forestry, drought-resistant and water-saving. There are two specs: Potassium SAP and Sodium SAP.
