TXG retention aid - Introduction
The copolymer of acrylamide and sodium acrylate is an important polymer material with many excellent properties and wide applications.
Nature:
-Acrylamide and sodium acrylate copolymer has good swelling and water solubility, and can quickly absorb a large amount of water.
-The copolymer has a high degree of polymerization and molecular weight, and the structure contains a large number of acid groups and alcohol groups.
-It has good moisture resistance, temperature resistance and chemical resistance, and has good resistance to most solvents, acids, alkalis and salts.
-It has relatively high water absorption and water retention, and can be used as an osmotic regulator in some applications.
Use:
-Acrylamide and sodium acrylate copolymer can be used in the field of water treatment and sewage treatment, used as flocculant, solid treatment agent, dehydrating agent, etc., to help the precipitation of suspended solids and solid-liquid separation.
-In the field of medicine and biotechnology, it can be used as a component of medical hydrogel, burn dressing and wound dressing.
-In the textile and paper industry, it can be used as a thickener, wetting agent and coating toughening agent.
-In personal care products, such as facial moisturizers, shampoos and moisturizers, it can be used as a thickener and moisturizer.
-can also be used as a soil conditioner, liquid fertilizer synergist and plant growth regulator.
Preparation Method:
The preparation of the copolymer of acrylamide and sodium acrylate can be achieved by polymerization. The commonly used methods include Free Radical Polymerization and ionic polymerization.
Safety Information:
-Under normal operating conditions, the copolymer of acrylamide and sodium acrylate is generally safe and will not cause serious harm to the human body.
-However, during preparation and use, care should be taken to avoid direct contact with eyes, skin and respiratory tract.
-such as inadvertent contact, should be promptly rinsed with plenty of water, and medical consultation professional doctor's advice.
-During storage and transportation, high temperature and impact should be prevented, and leakage and fire should be avoided.
