Abstract: An invert emulsion having double particle size distribution, the invert emulsion having a particle size distribution of latex particles between 20 nm and 70 nm and between 100 nm and 500 nm in the same invert emulsion system. A preparation method for an invert emulsion comprises: forming an emulsion A and an emulsion B having different particle sizes by controlling an emulsifier system and an emulsification means, and preparing in one step an invert emulsion the particle size of which has bimodal distribution by means of a three-stage polymerization reaction between the emulsion A and the emulsion B in the same system. The invert emulsion is used as a water treatment flocculant, a sludge dewatering agent and a papermaking auxiliary agent, and in particular, the sludge dewatering agent fabricated from the invert emulsion is used for dewatering sludge.

Abstract: Disclosed are a core-shell structure membrane scale inhibitor and a preparation method therefor, wherein the core-shell structure membrane scale inhibitor has a core emulsion obtained via emulsion polymerization, and a shell structure obtained via ultraviolet-light grafting functional monomers. The preparation method has first preparing a core by using an emulsion polymerization process, adding a reactive photo-initiator in the later stage of polymerization, so that the reactive photo-initiator is grafted on the surface of the core, and finally initiating the polymerization of functional monomers by means of ultraviolet light to obtain a core-shell structure membrane scale inhibitor. The surface structure of the core is modified, such that a large number of ionizable groups are grafted on the surface thereof, and thus, a large number of scaling ions such as Ca2+, Mg2+ and Al3+ can be adsorbed.
