The application of acrylamide
1. The preparation of polyacrylamide gel for electrophoresis determination of protein molecular weight, etc. Flocculant. Enhance the strength of paper. Improve the fiber quality. Binder.
2. Acrylamide is acrylamide and methyl acrylamide series products have been the most important. Since 1954, when used in industry, gradual growth. Mainly used for preparing polymer is soluble in water, and this kind of polyacrylamide can be used as an additive to improve the recovery rate of oil; Used as a flocculating agent, thickening agent and papermaking additives. A small amount of acrylamide is used to introduce hydrophilic center oil viscosity of polymer to improve, improve the softening point and improve the solvent resistance of the resin, and can be for dye by introducing a color center. Acrylamide is often used as a component of a light-sensitive polymer. In the vinyl polymer, can be used in the crosslinking reaction activity of the amide group. Acrylamide with certain monomer, such as vinyl acetate, styrene, vinyl chloride, vinylidene chloride and acrylonitrile copolymer obtained polymer with a variety of utility.
Main application fields: (1) oil field with the goods used for oilfield water injection well adjust injection profile. Will this product mixed with initiator, deoxidizer, injection of injection Wells high permeable zone. Under the formation polymerization into high viscosity polymer. Oil seal macroscopic throats, increase sweep volume, increase production rate. In addition, the product of the polymer or copolymer, can be used in the tertiary oil recovery, fracturing, water plugging, drilling slurry treatment and chemical grouting, etc.
(2) as a flocculating agent The goods of a part of the hydrolysate or graft copolymer with methyl cellulose, used for wastewater treatment and water processing factory.
(3) the soil conditioner The goods hydrolysate is used as soil conditioner, can make the soil aggregate, improve the liquidity, water, air permeability and water retention.
(4) fiber modified with resin processing will be amino formylation or acrylamide graft polymerization. Can be used to improve various fiber resin finishing, including synthetic fiber warp for dyeing and printing pastes and use, to improve the basic physical properties of fabrics, the shrink proof, crease resistant and feel good.
(5) the paper strengthening agent acrylamide and acrylic acid copolymer or partial hydrolysis polyacrylamide content, can be used as paper strength, strength agent instead of starch, water soluble amino resin has used or Shared.
(6) adhesives have polyacrylamide with phenolic resin solution and glass fiber adhesive, as well as synthetic rubber and pressure sensitive adhesive.
3. The determination of nucleic acid molecular weight. Dye synthesis. Plastic components. Adhesive. The preparation of polyacrylamide gel for electrophoresis determination of protein molecular weight.
4. Synthetic fiber industry and synthetic materials industry one of the important raw materials, homopolymer and copolymer of monomers and he is becoming more and more widely used in national defense construction, petrochemical, mineral processing, paper making, textile and water treatment, etc.
5. Used in the production of flocculating agent, dispersing agent, additives and water soluble polymer, etc.
