Description
Technical field
The invention belongs to microsphere preparation technology field, be specifically related to a kind of microballoon turner, the present invention is applicable to more than 1000 μm large scale polystyrene (PS) microsphere surfaces and prepares microballoon 180 ° upset docking in polyvinyl alcohol (PVA) coating procedure.
Background technology
Along with the development of China's superpower laser, the diametric requirements for laser inertial confinement fusion Physical Experiment multiple layer polymer pellet is also increasing, and therefore the research of large scale PS-PVA double-layer hollow microsphere preparation technology seems of crucial importance.Carry out this difficult problem of PVA uniform coating in order to solve at large scale PS microsphere surface, American Studies person D.Steinman etc. proposes spin-coating method.In this preparation process, the PS microballoon of 2/3 is immersed in certain density PVA solution, the rotating speed in addition suitable to it, keep after proposition rotating, due to the centripetal force that PVA drop produces in rotary course, make it sprawl to form certain thickness PVA coating at PS microsphere surface, after drying under thermal source, solidification, with vacuum adsorption fixture, microballoon is overturn, PVA coating is carried out to the other end of microballoon, repeatedly carry out aforesaid operations and can obtain PS-PVA double-layer ball.
Although PVA can be coated in large scale plastic microsphere surface by spin-coating method, but because the method needs interval border accurate coatings, but when adopting empty suction jig to carry out manual overturning to microballoon, be difficult to realize PVA coating perfection docking, the problem such as PVA layer thickness repeatedly can be caused after coating uneven.
Summary of the invention
Accurate docking is difficult in order to solve PVA coating interval border in prior art, cause the problem of PVA coating uniformity difference, the invention provides a kind of microballoon turner, the present invention is applicable to the microballoon turner of spin-coating method to PS microballoon 180 ° upset docking in large scale PS microsphere surface PVA coating.
Microballoon turner of the present invention, is characterized in: described device comprises clamper, positioning table, handle reverse, movable sealing structure, seal cover, negative port, and movable sealing structure contains lock chamber, sealing ring and turning cylinder; Clamper is connected with one end of turning cylinder, and seal cover is connected with the other end of turning cylinder; Handle reverse is fixedly connected with turning cylinder, positioning table and handle reverse compact siro spinning technology; Lock chamber is connected with turning cylinder, and turning cylinder is provided with annular groove for the formation of stable vacuum and pore; Negative port is fixedly connected with lock chamber.
Described turning cylinder is hollow convex cylinder tube shape plastic construction.
Described handle reverse is provided with locating piece, and locating piece width is greater than the external diameter of turning cylinder, and with the base two edges of handle reverse apart from equal.
Described positioning table is the ledge structure with horizontal plane and vertical plane.
Described seal cover is the threaded cap containing rubber sheet gasket.
Described negative port and annular groove are located along the same line, and negative port internal diameter is greater than the bore of annular groove.
Described pore is positioned on described annular groove.
Microballoon turning appliance of the present invention has following advantage: simple to operation, condition is gentle, is easy to control, and can complete 180 ° of upset docking of polystyrene microsphere in large scale Surfaces of Polystyrene Microparticles polyethylene coating.

Detailed description of the invention
As depicted in figs. 1 and 2, microballoon turner of the present invention comprises clamper 1, turning cylinder 2, positioning table 3, handle reverse 4, movable sealing structure, seal cover 8, negative port 10 and auxiliary member, and wherein turning cylinder 2 is hollow convex cylindrical tube plastic construction.Clamper 1 is installed on one end of turning cylinder 2, and the diameter according to PS individual layer ball to be coated determines capillary inner diameter size in described clamper 1.Seal cover 8 is the threaded caps containing rubber sheet gasket, is installed on turning cylinder 2 other end, so that remove the tamper in turning cylinder 2 pipe.Turning cylinder 2 is through movable sealing structure, handle reverse 4 and positioning table 3.Movable sealing structure is formed by turning cylinder 2 and lock chamber 9 press seal circle 7.Turning cylinder 2 is arranged in lock chamber 9 local and adopts annular groove 6, and be provided with pore 5 on annular groove 6, thus provide stable vacuum for this microballoon turner.Negative port 10 is fixed on lock chamber 9, and with annular groove 6 generally within a straight line, negative port 10 internal diameter need be greater than annular groove 6 width.Fig. 3 and Fig. 4 is the structural formula schematic diagram of the handle reverse 4 in the present invention.Handle reverse 4 is provided with locating piece 11, and handle reverse 4 width is greater than the external diameter of turning cylinder 2, and locating piece 11 needs equal with handle reverse 4 base two edges distance simultaneously, to guarantee that upset front and back handle reverse 4 is on same straight line.Fig. 5 and Fig. 6 is the structural representation of the positioning table 3 in the present invention.Positioning table 3 is for having the ledge structure of horizontal plane and vertical plane.Handle reverse 4 is fixed on turning cylinder 2, positioning table 3 and handle reverse 4 compact siro spinning technology, when negative pressure is opened, realize the accurate upset of microballoon 180 ° by operation handle reverse 4, thus complete spin-coating method PVA coating interval border in large scale PS microsphere surface PVA coating is accurately docked.
The present invention can realize overturning at any angle in 180 ° in microballoon preparation process.
