Non-polyacrylamide (N-PAM) is a common inorganic salt-based water-soluble polymer. It has excellent water absorption properties and high gel properties, so it is widely used in many different fields.
1.Physical properties
N-PAM is a white crystalline powder that is odorless and non-toxic. It can be dissolved in water to form a colorless and transparent solution. The chemical formula of N-PAM is (C3H5NO)N, where N represents the degree of polymerization, which determines its molecular weight and performance.
2.Water absorption
N-PAM has excellent water absorption. In water, N-PAM absorbs water to form a gel and can absorb its own weight of water. This makes N-PAM used as a water-absorbing material in many fields.
3.Gel properties
Due to its high water absorption properties, N-PAM can form a gel state. The gel is a reticulated structure that is able to hold a large number of water molecules. This feature makes n-pam suitable for a variety of applications in a variety of fields.
4.Fields of application
4.1 Water treatment
N-PAM is widely used in the field of water treatment, mainly for flocculation, sedimentation and filtration. It can condense suspended solids and impurities in the water and make them settle down, thereby purifying the water quality.
4.2 Soil solidification
N-PAM can increase the structure and stability of the soil by binding to particles in the soil. This method is known as soil solidification and is commonly used for soil improvement and to prevent soil erosion.
4.3 Prepare the gel
Due to its gel properties, N-PAM is used in the preparation of various gel materials such as hydrogels, soft gels, etc. These gel materials are widely used in medical, cosmetic, agricultural and other fields.
4.4 Petroleum exploitation
In oil extraction, N-PAM can be used as a thickener. It can increase the effect of water flooding and improve the efficiency of oil recovery.
4.5 Textile industry
N-PAM can be used as an additive in textiles to improve the softness and washability of textiles.
5.Security
N-PAM is a non-toxic compound that does not pollute the environment. During use, care needs to be taken to avoid inhaling dust and ** contact to avoid causing allergies or irritation.
Summary:
Non-polyacrylamide is an inorganic salt-based water-soluble polymer with water absorption and gelling properties. It has a wide range of applications in fields such as water treatment, soil solidification, gel preparation, oil extraction, and textile industry. N-PAM is a non-toxic and non-polluting compound, but it is still necessary to pay attention to safety issues when using it.
