With fast development of deep corn processing industry, people gradually pay more attention to its advantages, the products become various. Chemical products made of corn are popular. Let’s introduce in detail starch-base IPN high water absorption resin technology.
Crylic acid, acrylamide and starch, in condition of poval, polymerize to net structure which crosslinks to IPN. The poval is controlled to 18 of the total of crylic acid, acrylamide and starch; Dosage of methylene bisacrylamide is the same as that of crylic acid as a cross-link agent. Initiator is 108 of crylic acid. Proportion between total starch and acrylamide is 1:3.5; crylic acid and acrylamide is 1.2:2.1.
Microwave technology of deep corn processing industry is widely used to synthesize high water absorption resin, greatly shortening compounding time and saving raw materials, which decreases costs to a high degree. Microwave radiation, in place of common heating method, heats the materials internally, clear, energy saving and easily controlled. Compared with ultraviolet ray, X ray and electron beam, it is cost-effective, secure, highly efficient and easily operated. In macromolecule field, microwave technology is widely used in materials processing and solidification.
In recent years, microwave technology of deep corn processing industry is gradually applied to polymerization reaction. As the high frequency microwave reacts to polar dielectric, it contributes to fast heat increase of monomer or liquid. Its similar vibrating frequency to chemical group changes molecule structure, activates some groups without damaging macromolecule chain, greatly speeding up reaction.
