The realization that closely cooperates relying primarily on silica gel sealing pad, conical seal ring and nut owing to sealing structure seals work
With, therefore it is required that the diameter of through hole is slightly less than the extracapillary diameter passed through on glue sealing ring, conical seal ring through-hole diameter is slightly
More than stainless steel capillary overall diameter, the length of capillary tube A and capillary tube B controls to reach to be preferred in the middle part of glass bushing with end,
It is easy to observe drop in capillary tube by sleeve pipe and shapes situation with breast grain.
The present embodiment before assembling, first carries out the hydrophobic treatment of capillary glass tube, prepares 1%(volume ratio) octadecane
Pending capillary tube, as AL, is soaked 24 little in 10%HNO3 solution by base trimethoxy silane/toluene solvant
Time, clean with deionized water after taking-up, supersound process 5min in ethanol solution, the alkylating reagent of preparation before then using
Process at 75 DEG C about 3 hours, be dried after cleaning with EtOH Sonicate after taking-up.
After device assembles, aqueous phase in preparing, oil phase and outer aqueous phase solution.The present embodiment is interior water with deionized water
Phase, the fluorobenzene solution of polystyrene is oil phase, and polyvinyl alcohol water solution is outer aqueous phase.Three capillaries need to be seen under the microscope
Examining, inside and outside wall is without substantially polluting, and port is without obvious defect, and capillary glass tube B need to be through hydrophobic treatment.According to group shown in Fig. 1-3
Installing generator, capillary glass tube C12 outlet is positioned at bottom and generator vertically downward.Use flexible pipe by sample feeding pipe and conjunction
Suitable syringe connects, and respectively filled with interior aqueous phase, oil phase and outer aqueous phase solution in syringe, this example uses medical injection pump automatic
Control the flow of liquid in syringe.Generator assemble after when using first, need to be passed through in three sample feeding pipes of generator from
Sub-water is hunted leak.
When starting to prepare breast grain, it is passed through in the sample feeding pipe of injection port I successively in the sample feeding pipe of deionized water, injection port III
It is passed through polyvinyl alcohol water solution, treats that deionized water is full of capillary glass tube B9, poly-vinyl alcohol solution is full of capillary glass tube C12
After, start in the sample feeding pipe of injection port II, be passed through polystyrene/fluorobenzene solution.Observe glass between threeway A4 and threeway B13
The port of capillary glass tube A3 in sleeve pipe, from the beginning of capillary glass tube A3 port, will form continuous print in capillary glass tube B9
Interior aqueous phase droplets.Generate as do not observed aqueous phase droplets in continuous print, interior aqueous phase and Oil phase flow rate need to be adjusted, as in glass capillary
When can only see the two phase flow along glass wall flowing in pipe B9, then it is owing to the hydrophobic treatment of middle capillary tube is incomplete, solves
Method is off fluid input, the capillary glass tube B9 that replacing processed.Formed aqueous phase droplets together with oil phase from glass
Glass capillary tube B9 flows to capillary glass tube C12, forms independent water in oil breast grain at capillary glass tube B9 port.By observing
Glass bushing between threeway B13 and straight molded cannula is it can be seen that the newborn grain formational situation of capillary glass tube B9 port, such as breast grain
Breakdown of emulsion occurs when going out the port of capillary glass tube B9, then the port of capillary glass tube B9 there may be burr or hydrophobic treatment is lost
Effect, the capillary tube that need to more renew, as breast grain sticks in the inwall of capillary glass tube C12 continuing downward output procedure, then be due to
Capillary glass tube C12 inwall is contaminated, same replacing capillary glass tube C12.
By adjust suitable three-phase flow rate of liquid, till generator exports independent newborn grain continuously, breast grain interior
External diameter is relevant with the fluid properties of capillary size, three-phase flow velocity and each phase liquid, needs to investigate according to specific experiment to confirm, three
Phase liquid can select suitable liquid according to breast grain composition requirements.
Having prepared rear generator needs and cleaned in case next time uses, cleanout fluid uses very good dissolving to polystyrene
The oxolane of property.First three-phase fluid input is stopped, the syringe note being full of oxolane oil phase input used
Emitter is replaced, and the syringe input of outer aqueous phase used is replaced with the syringe being full of deionized water.Open three-phase liquid
Driving syringe pump, to flexible pipe, oil phase is purged completely, more repeatedly cleans 2 times.Close injection port II, continue to inject interior aqueous phase
Device also uses the syringe of full oxolane to replace, and repeatedly cleans oil phase solvent remaining in can washing generator for 2 times,
Generator can reuse after drying.
Embodiment 2
A kind of oil-in-water type breast grain of the present embodiment preparation, method is substantially the same manner as Example 1, and difference is to need to dredge
The capillary tube that water processes is changed into capillary glass tube A3 and capillary glass tube C12 by capillary glass tube B9, and it is molten that injection port I enters interior oil phase
Liquid, injection port II enter aqueous phase solution, injection port III enters outer oil-phase solution.Each phase liquid is also according to the emulsion feature needing preparation
Carry out selecting preparation.
Embodiment 3
A kind of hollow polymer microsphere of the present embodiment preparation, method is substantially the same manner as Example 1, and difference is breast grain
Use flask to receive breast grain after generation, be placed in rotary evaporator, after rotating the elevated cure regular hour, obtain internal containing
The polystyrene microsphere of water, more hollow polystyrene microsphere can be formed after 50 DEG C of oven dryings.Obtain as required
Polymer microballoon component requirements, selects corresponding suitably polymer oil-phase solution.The mode of microsphere solidification can be according to polymerization
Thing characteristic is specifically chosen, and as the modes such as emulsion polymerization or photocuring all can use, initiator can be introduced by inside and outside aqueous phase.
Embodiment 4
A kind of solid polymeric microspheres of the present embodiment preparation, method is substantially the same manner as Example 3, and difference is reality
Injection port III in example 3 is closed or is passed through the solution as injection port II and serves as wash fluid, passes through similar solidification and does
Solid polystyrene microsphere is obtained after dry.
This utility model is not limited to above-mentioned detailed description of the invention, and person of ordinary skill in the field visualizes from above-mentioned
Sending out, without performing creative labour, done all conversion, within all falling within protection domain of the present utility model.
