Description
Technical field
The present invention relates to a kind of water-oil emulsion breaking method, specifically a kind of water-absorbing resin dry glue powder and the application in the water-oil emulsion breakdown of emulsion thereof.
Background technology
For water-oil emulsion, traditional breaking method has chemical method, biological process, electrical method, hot method, mechanical process etc.Wherein chemical method and electrical method breakdown of emulsion efficient are high, use the extensivelyst, but they also respectively have deficiency.The interpolation of chemical method emulsion splitter is formed original emulsion system and is become more complicated, and the result is restricted its application in processes such as continuous separation.Electrical method is low for the higher demulsification with the bigger emulsion system of interfacial film intensity of water cut, and has short circuit and potential safety hazard such as the electric field that collapses.Therefore, safety, the exploitation of novel physics breaking method have efficiently become a research focus.Physics breakdown of emulsion methods such as polishing, wetting coalescence method and freeze-thaw method have appearred in recent years; It is not to add in emulsion system that chemical agent changes water-oil interface character or structure reaches the breakdown of emulsion purpose; But through apply certain environment pressure to emulsion system; Such as power, electricity, heat, sound etc., impel the instability of emulsion system.
The breakdown of emulsion mechanism and the polishing of wetting coalescence method comes down to identical, and its operating process is also quite similar.Select the tiny water wetted material of particle as coalescing medium, after water-soaked, add in the milk sap, and constantly stir.Dispersive water droplet wetting and absorption on the coalescing medium surface earlier in the whipping process; Afterwards the water droplet in the milk sap main body bump with the water droplet that is adsorbed in dielectric surface earlier, coalescence; When the water droplet of coalescence was grown up to a dimensioning, stirring the drag force that is produced can remove it from dielectric surface.So the wetting absorption of successive, collision, coalescence, remove, finally cause the complete phase-splitting of profit.This physics breaking method key in application is the control of selection, churning time and the stir speed (S.S.) of wetted media.Though wetting coalescence method and polishing have lot of advantages; But in actual mechanical process, also all come with some shortcomings: for the too high emulsion system of viscosity; Need the mechanical power of input very big, increased behind the breakdown of emulsion the tiny abrasive particles or the separation problem of coalescing medium.It is the circulation change of utilizing the temperature field that freeze-thaw is induced breakdown of emulsion, and milk sap profit two is undergone phase transition mutually, causes the instability of emulsion system.Because the production development of milk sap food such as ice-creams, food flavouring makes the Application Research of this technology in type milk sap relatively early, develops also comparative maturity.Yet this method energy consumption is big, and not strong for the breakdown of emulsion practicality of extensive milk sap.
Summary of the invention
In order to overcome the problem that prior art exists, the purpose of this invention is to provide a kind of water-absorbing resin dry glue powder and the application in the water-oil emulsion breakdown of emulsion thereof.This water-absorbing resin dry glue powder preparation is simple, is easy to suitability for industrialized production; The dehydration breakdown of emulsion is easy to operate, and equipment requirements is low; The water-absorbing material dehydrating amount is big, and is easy to Separation and Recovery, recycle.
The present invention realizes through following technical scheme:
A kind of water-absorbing resin dry glue powder is characterized in that: this dry glue powder is processed by following raw material weight component, and said raw material weight component is a vinylformic acid 10 ~ 40%; Sodium hydroxide 5-20%, N hydroxymethyl acrylamide 0.5-8%, ammonium peroxydisulfate 0.5-5%; S-WAT 0.5-2%, all the other are water; Except that vinylformic acid, other material is mixed with the aqueous solution, react with aqueous sodium hydroxide solution and vinylformic acid, the control degree of neutralization adds N hydroxymethyl acrylamide, ammonium peroxydisulfate, sodium sulfite solution, at 50-80 then at 60-85%
oReact under the C and make hydrogel; Hydrogel is cut into small pieces places baking oven to dry, and obtains the water-absorbing resin dry glue powder after the pulverizing.
Among the present invention, said water-absorbing resin is one or more mixtures of polyacrylate, acrylate-acrylamide copolymer, acrylate-hydroxymethyl acrylamide copolymer, acrylate-starch or cellulose graft copolymer.
The application of a kind of water-absorbing resin dry glue powder in the water-oil emulsion breakdown of emulsion adds the water-absorbing resin dry glue powder in milk sap, through mechanical stirring, and the spontaneous absorption moisture of water-absorbing resin and swelling makes the milk sap dehydration cause breakdown of emulsion.The water-absorbing resin dry glue powder can be kept in the encloses container.
Synthetic High hydrophilous resin dry glue powder of the present invention, the moisture in can rapid absorption milk sap and cause emulsion breakdown.Because water-absorbing resin suction back swelling gets final product Separation and Recovery through the simple filtration operation, after dry, reuses.
The present invention is a kind of water-oil emulsion breakdown of emulsion novel method; It is a kind of ROHM salt resin suction breakdown of emulsion method; The polyacrylate resin dry rubber powder that will have the high-hydroscopicity ability joins in the water-oil emulsion, controls certain temperature, under mechanical agitation, carries out breakdown of emulsion.The water-absorbing material that adopts is high suction ROHM salt resin, and the moisture that directly absorbs in the milk sap through high-absorbent material causes milk sap dehydration breakdown of emulsion, and itself is swelling owing to suction, and the variation that particle increases helps the Separation and Recovery of water-absorbing material.
Water-absorbing resin dry glue powder preparation of the present invention is simple, is easy to suitability for industrialized production.The dehydration breakdown of emulsion is easy to operate, and equipment requirements is low.The water-absorbing material dehydrating amount is big, and is easy to Separation and Recovery, recycle.The present invention is applicable to the breakdown of emulsion to water-oil emulsion.
