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 height are most widely used, 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 demulsification of the bigger emulsion system of the higher and interfacial film intensity of water content, 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 coalescent method and freeze-thaw method have appearred in recent years, it is not to add that chemical agent changes water-oil interface character or structure reaches the breakdown of emulsion purpose in the emulsion system, but by apply certain environment pressure to emulsion system, such as power, electricity, heat, sound etc., impel the instability of emulsion system.
Breakdown of emulsion mechanism and the polishing of wetting coalescent 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.The water droplet that disperses in the whipping process wetting and absorption on the coalescing medium surface earlier, water droplet in the milk sap main body bumps, gathers also with the water droplet that is adsorbed in dielectric surface earlier afterwards, when poly-water droplet was also grown up to a dimensioning, stirring the drag force that produces can remove it from dielectric surface.Continuous so wetting absorption, collision, poly-also, 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 coalescent 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 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-phase is undergone phase transition, and causes the instability of emulsion system.Because the production development of milk sap food such as ice-creams, food flavouring is used relatively early the research of this technology in type milk sap, 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 is achieved through the following technical solutions:
A kind of water-absorbing resin dry glue powder is characterized in that: this dry glue powder is made by following raw material weight component, and described raw material weight component is 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 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, described 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, by 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.
The High hydrophilous resin dry glue powder that the present invention synthesizes, 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 by the simple filtration operation, reuses after drying.
The present invention is a kind of water-oil emulsion breakdown of emulsion novel method, it is a kind of polyacrylic acid salt resin suction breakdown of emulsion method, the polyacrylate resin dry rubber powder that will have the high-hydroscopicity energy joins in the water-oil emulsion, controls certain temperature, carries out breakdown of emulsion under mechanical agitation.The water-absorbing material that adopts is high suction polyacrylic acid salt resin, and the moisture that directly absorbs in the milk sap by high-absorbent material causes milk sap dehydration breakdown of emulsion, and itself is swelling owing to suction, and the variation that particle increases is conducive to 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.
Embodiment
Synthesizing of water-absorbing resin dry glue powder:
In the cylinder open container, add earlier vinylformic acid 30 grams, start agitator after, slowly add 20% aqueous sodium hydroxide solution, 55 grams again, control acrylic acid degree of neutralization at 60-85%.When temperature drops to room temperature in the question response container, add 20%N-hydroxymethylacrylamwater water solution 25 grams then successively; 10% peroxy-disulfuric acid aqueous ammonium, 6 grams; 10% sodium sulfite aqueous solution, 4 grams.Rising temperature to 50
oC, and keep polyreaction to get the sodium polyacrylate hydrogel in 1 hour.Be drying to obtain the water-absorbing resin dry glue powder after hydrogel is cut into small pieces.
The application of water-absorbing resin dry glue powder in the water-oil emulsion breakdown of emulsion:
The preparation of water-oil emulsion: with dewatered solid crude oil heat fused in water-bath in oil field, Jiangsu, mix the formation simulated oil with tasteless kerosene by 4:3 (volume ratio) while hot, getting an amount of simulated oil and deionized water then mixes with 7:3 (35mL simulated oil and 15mL deionized water), under the 3000rpm condition, stir 10min with high-shear emulsion machine and make water-oil emulsion, pour in the 100mL tool plug Erlenmeyer flask stand-by.
The measuring method of water regain: keeping water-absorbing resin dry glue powder consumption is 0.5 gram (be about water-oil emulsion total mass 1%), add the resin dry rubber powder under the control temperature and stir, after a period of time the hydrogel of swelling is weighed after with nylon net filter, the be absorbed quality of water is calculated dehydration rate.Get several parallel tests, can measure different time resin dry rubber powder to the dehydration demulsification of milk sap.Suction demulsification under the differing temps sees Table 1 to table 3.
