A system and method for delivering a treatment fluid to a wellbore by emulsifying the treatment fluid with a continuous fluid in a flowline. The treatment and continuous fluids are combined in a mixer that is separate from containers that retain the fluids. In an example where the mixer is a venturi, the continuous fluid flows into an inlet on an entrance end of the venturi, and the treatment fluid flows into an inlet that is at a flow restriction in the venturi. The continuous fluid experiences a localized decrease in pressure at the restriction, which is due to a localized increase in flow rate at the restriction. The pressure decrease induces the treatment fluid into the venturi, where the treatment fluid is dispersed into droplets within the continuous fluid, and that forms a treatment emulsion. The treatment fluid escapes from within the treatment emulsion when in the wellbore.

The disclosure discloses a milk protein concentrate-based microencapsulation wall material and microcapsules, and belongs to the technical field of microcapsule preparation.

What is proposed is an emulsifying system for an internal combustion engine, wherein the emulsifying system comprises an emulsifying device for producing a water-fuel emulsion and an injector for injecting the water-fuel emulsion in a combustion chamber, the emulsifying device being arranged within the injector. Also proposed is an emulsifying method for preparing a water-fuel emulsion for an internal combustion engine, wherein fuel is pressurized in a fuel pressure accumulator and water is pressurized in a water pressure accumulator and fed separately to an injector for injecting the fuel and water into an associated combustion chamber, and/or fuel and water are emulsified by means of an emulsifying device that is integrated into an injector.

The invention relates to a method for preparing emulsions.

In order to create a new method for preparing emulsions, in which homogenous oil droplets as small as possible can be generated with an energy input as low as possible, it is proposed in the scope of the invention, that at least two liquid streams of liquids that cannot be intermixed with one another are pumped through separate openings with defined diameters, in order to achieve flow velocity of the liquid streams of more than 10 m/sec., and in that the liquid streams collide at a collision point in a space, wherein the resulting emulsion is discharged from the space through an outlet.

By the collision of the liquid streams with high flow velocities, in which a plate-shaped collision plate is formed in the collision point, a homogenous emulsion having an oil droplet size of less than 1 m is achieved due to the kinetic energy, which is accordingly very stable as well. No further energy input, such as shear forces, is required to that end.

A latex of a synthetic rubber, wherein the content rate of a particle having a particle size of 5 m or more in a particle size distribution of a synthetic rubber particle included in the latex, as determined on a number basis, is less than 3,000 ppm by weight. A latex of a synthetic rubber is excellent in mechanical stability and can provide a film molded article such as a dip molded article excellent in tensile strength and elongation.

The present invention relates to a method and device for emulsifying emulsion explosive: an oil phase and a part of a water phase having undergone split-flow enter a first stage coarse emulsion mixer; after mixing, the mixture together with a part of the water phase having undergone second stage split-flow enters a second stage coarse emulsion mixer; the obtained mixture together with a part of the water phase having undergone third stage split-flow enters a third stage coarse emulsion mixer for mixing; forming a coarse emulsion matrix after multiple stages of mixing, and finally completing emulsification after mixing in a multi-stage fine emulsion mixer. The method and device mix the water phase with the oil phase multiple times according to a desired ratio, thus greatly reducing the stored explosive, with no mechanical stirring or shearing, with no heat accumulation, and with low pressure, without requiring matrix pumping, thus enhancing safety.
