| titleOfInvention | Method for preparing solid water-soluble high-molecular polymer by ultraviolet light initiation |
| abstract | The invention discloses a method for preparing a solid water-soluble high molecular polymer by ultraviolet light initiation, which comprises the following steps: adding deionized water, a functional monomer, a chelating agent, a cosolvent and a chain transfer agent/cross-linking agent into a batching tank to prepare a pre-polymerization solution; adjusting the temperature and the pH value of the prepolymer, and deoxidizing the prepolymer through a packed tower; mixing the pre-polymerization liquid after the deoxidization with an initiator to obtain a polymerization liquid, and feeding the polymerization liquid into a polymerization device for polymerization reaction; the ultraviolet light intensity of the ultraviolet light initiating mechanism is gradually increased to control the speed of the polymerization reaction in the initial polymerization stage, the middle polymerization stage and the later polymerization stage. The method optimizes the polymerization method, controls the light intensity of ultraviolet light and the temperature control of polymerization reaction in each polymerization reaction stage, ensures that the produced product has the characteristics of high molecular weight and low residue, and can be applied to the fields of water treatment, sludge dewatering, papermaking, oil and gas mining mineral washing and selecting and the like. |
