A glass spinning nozzle is composed of glass spinning plate having spinning orifices on and hat metal shell, of which the compressed inner surface of glass spinning plate is convex spherical surface and its filament outgoing face is concave spherical surface. The thickness of glass spinning nozzle is 1.4-2 mm, its length-diameter ratio is 20:1 to 30:1 and it can stand operation pressure of 1.2-1.5 MPa.
Description
Technical field
The present invention relates to a kind of glass spinneret and preparation method, relate to or rather a kind of with the textile fabric production manufacturing of ordinary optical glass, that have high length-diameter ratio with glass spinneret and preparation method.The field of components that belongs to weaving usefulness.
Background technology
As everyone knows, glass spinneret is made of glass spinnerets that has spinneret orifice and hat metal shell, and wherein the pressurized inner surface of glass spinneret is the convex sphere, and the wire vent actinal surface is the matrix sphere.Glass spinneret is applicable to wet type chemical fibre spray silks such as viscose spray silk, solvent spin, and can substitute plation metal spinning head and tantalum metal spinning head.Two kinds of chemical fibre spray silk branch melt-spun and wet spinnings, viscose spray silk, solvent spinning etc. all belong to wet spinning.What wet spinning spray silk before this adopted all is the metal spinning head, has disclosed the multiple spinning head that is used for wet spinning technology as Chinese patent CN1139959A, CN1352325A, day disclosure special permission communique JP2003-342824A, a JP2002-348723 etc.These spinning heads all are to make with the metal alloy of gold, platinum, rhodium and tantalum etc., wherein plation for the alloy that contains 49% (weight) Pt heat-treat to Vickers hardness be 330, the alloy Vickers hardness that contains 30% (weight) Pt is 230.Thickness as spinning head sheet material is 0.2～0.8mm, adopts the Metal-Piercing moulding.For the spinneret orifice draw ratio below 0.5 millimeter is 1: 1～2: 1, and draw ratio (being the length of spinneret orifice and the ratio of bore dia) is the important technology index of wet spinning spinning head.This is because spinning slurry is in the flow regime of the constraint that is squeezed in the micropore of spinning head (plate), after the outflow micropore enters the space, just become the thread of free state, and be subjected to the stretching of back operation, just have at the outlet area of spinning head (plate) like this that a kind of " expanded phenomenon " is expanded " melt fracture " will to occur when serious, this moment, strand was rough, had a strong impact on the spinning technique quality, also was unfavorable for the raising of spinning speed.
Summary of the invention
The object of the invention is to provide a kind of glass spinneret made from ordinary optical glass that has spinneret orifice, described spinning head is to be made of glass spinnerets that has spinneret orifice and hat metal shell, the profile of glass spinneret is carnival hat shape, wherein the pressurized inner surface of glass spinneret is the convex sphere, and the wire vent actinal surface is the matrix sphere.The thickness of glass spinneret is 1.4～2 millimeters, and the aperture is 40～100 microns, and its draw ratio can reach 20: 1～30: 1, has overcome " the expanded phenomenon " of fiber well, improves the quality of spinning.Fix with organic bond between hat metal shell and glass spinnerets.
Another object of the present invention is to provide a kind of manufacture method of above-mentioned glass spinneret, and it comprises two aspect contents, and the one, the manufacturing of the method for the assembling spinneret orifice in bulk glass and the glass spinneret of profiled-cross-section spinneret orifice.Second aspect is that spinning head contains and is not more than 3000 spinneret orifices, 330～450 microns of pitch-rows, the hole is distributed in the circumferential area that is not more than 22 millimeters of diameters, draw ratio up to 20: 1～manufacturing of the glass spinneret that 30: 1 viscose spinning is used.Spinning head has the glass spinnerets and the shell that have spinneret orifice to constitute, and the profile of glass spinneret is hat, and wherein the pressurized inner surface of glass spinneret is the convex sphere, and the wire vent actinal surface is the matrix sphere.The radius of curvature of concave shape sphere is 80～200 millimeters; Can bear the operating pressure of 1.3～1.5Mpa.The radius of curvature of convex spherical is 91.4～202 millimeters
First aspect is achieved in that the arrangement regulation according to spinneret orifice in the manufacture method of the present invention, follow procedure is imbedded wire on bulk glass, obtain being inlaid with regularly arranged wire group's bulk glass material, carry out acid leach then, finally obtain required spinneret orifice.Same principle uses the groups of metal filaments of different geometric shapes to be contained in the bulk glass, can produce various profiled-cross-section spinneret orifices easily.As rectangle, hexagon etc.
Second aspect is achieved in that and is inlaid with regularly arranged bulk glass material wiry in the manufacture method of the present invention, by the nozzle design requirement, intercept certain thickness sheet glass, cross-wise direction is perpendicular to wire, make the degree of depth of spinneret orifice approach the thickness of glass spinneret substantially, thereby produce draw ratio up to 20～30 spinneret orifice.
Description of drawings
Fig. 1 is the contour structures schematic diagram of glass spinneret provided by the invention
Fig. 2 is the generalized section of glass spinneret
1-hat metal shell among the figure, the glass spinnerets of 2-spherical section, the organic knot agent of 3-, 4-spinneret orifice.
The specific embodiment
Narrate substantive distinguishing features of the present invention and obvious improvement below in conjunction with accompanying drawing and table 1 embodiment, but the present invention is confined to embodiment by no means.
Glass spinneret is made up of hat metal shell 1 and the glass spinnerets 2 that has spinneret orifice that is embedded in its bottom, and 2 of metal-back 1 and glass spinneretss are with organic binder bond 3 sealing and fixing.Have spinneret orifice 4 on the glass spinnerets 2, quantity 3000 holes of spinneret orifice, 65 microns in aperture, 330～450 microns of pitch-rows, pore-size distribution is in 22 millimeters the circumferential area being not more than diameter.Operating pressure when spraying silk in order to satisfy chemical fibre, while is according to the draw ratio requirement of spinneret orifice, glass spinnerets 2 is made into the glass flake of uniform thickness spherical shape, its pressurized inner surface is a convex spherical, the wire vent actinal surface is the spill sphere, the spill sphere curvature radius is at 90 millimeters, and the radius of curvature of convex spherical is 91.4 millimeters, and the thickness of glass spinnerets is 2 millimeters.The glass spinneret of this structure can bear the pressure of 1.5Mpa, and the major diameter specific energy reaches 30: 1.It is to imbed the circular metal silk on bulk glass when making, and then through acid leach, obtains the spinneret orifice in 3000 holes, at the thick sheet glass of vertical wire direction intercepting 2mm, thereby makes the glass spinneret shown in Fig. 1,2.
