Problems solved by technology
[0005] 1. Intermittent production process, many auxiliary equipment, complex operation and high labor intensity
[0006] 2. The polymerization reaction needs to be carried out under high-speed stirring, which requires high speed and precision of the stirrer
Large-scale production requires multiple sets of batch reactors, which pose safety risks and high labor intensity, making it difficult to produce on a large scale and limiting production capacity
[0009] In view of the technical shortcomings of the current existing devices, a continuous process and key tubular reaction equipment are provided to solve the problems of a large number of equipment in the prior art, intermittent operation, uneven mixing of the reactor, high stirring requirements, and slow heat transfer speed

Description
technical field [0001] The application belongs to the field of polymer microsphere production devices, and in particular relates to a device and method for continuous production of polymer microspheres. Background technique [0002] At present, most of the domestic emulsion / inverse emulsion polymerization technology uses liquid paraffin, kerosene, white oil and other media as the continuous phase, and monomer aqueous solutions such as acrylamide and acrylic acid as the dispersed phase. N,N'-methylenebisacrylamide, formaldehyde As cross-linking agents, Span, TWeen and OP series surfactants are emulsifiers, and the initiation system adopts redox system and water (oil) soluble initiator system. [0003] Inverse emulsion polymerization is a major process for the production of polymer microspheres, and it is a newly developed branch in the field of emulsion polymerization research. Inverse emulsion polymerization refers to dispersing an aqueous solution of a water-soluble monome...
