1、 Application field
Acrylamide, whose molecular formula is CH2 = chconh2, is an unsaturated amide with two reactive active centers of amide group and double bond. It is the simplest and most important amide compound with active chemical properties. The main uses of acrylamide are as follows: synthesis of water-soluble polymers; Increase the adhesion of hydrophilic center of lipophilic polymer, softening point of resin and solvent resistance; It can also be used as a crosslinking agent for vinyl polymers. Among them, polyacrylamide polymers are one of the most widely used varieties of water-soluble polymers. They are known as "Baiye additives" and "universal products". They are mainly used in petroleum exploitation, metallurgy, construction, textile, sugar making, medicine, agriculture and other fields.
2、 Product characteristics
The molecular weight of acrylamide (AM) is 71.08 and the density is 1.122g/cm3. The pure product is white flake crystal, soluble in water, acetone and ethanol and slightly soluble in benzene. It is stable in the shade and easy to polymerize under the melting point or UV irradiation. It is flammable and can burn in case of open fire. Decompose under high heat and release corrosive gas. It belongs to category 6.1 poison and is harmful to the central nervous system.

4、 Method of use
Acrylamide polymerizes with acrylic acid (AA), sodium acrylate, 2-acrylamide-2-methylpropanesulfonic acid (AMPS) and other anionic intermediates containing active double bonds to form anionic polyacrylamide copolymer. Cationic polyacrylamide copolymer was synthesized with acryloyloxyethyl trimethylammonium chloride (DAC), methacryloyloxyethyl trimethylammonium chloride (DMC), dimethyl diallyl ammonium chloride (DMDAAC) and other active cationic monomers. Acrylamide can also synthesize non-ionic polyacrylamide by homopolymerization. Anionic polyacrylamide can be synthesized by subsequent alkali hydrolysis process. 5、 Packaging, storage and transportation packaging shall be sealed and not in contact with air. Paper plastic three in one composite bag shall be used for packaging, with each bag of 25kg. The safe packaging method can also be determined according to the customer's requirements. The product is easy to absorb moisture. It is stored in a cool, ventilated and dry warehouse, protected from moisture and rain, and sealed for storage. Keep away from kindling and heat sources, avoid contact with oxidants, acids, alkalis, copper, iron, aluminum and other materials, store them separately from edible chemicals and avoid mixed storage. The shelf life is 1 year. If it exceeds the storage life, it can continue to be used without self polymerization. Before transportation, check whether the package is complete and sealed. During transportation, ensure that the package does not leak, collapse, fall or damage. It is strictly prohibited to mix with acids, oxidants, food and food additives, as well as copper, iron, aluminum and other materials. During transportation, it shall be protected from sun exposure, rain and high temperature.
