Description

Spinner for Making Two-Component Glass Fibers

In the present invention, in producing a glass fiber by spinning the molten glass, two kinds of molten glass having different chemical composition components are simultaneously released through one orifice to produce a two-component glass fiber. It relates to a spinner for producing two-component glass fibers.

In general, the aggregate collected as a single-component, short-fiber glass fiber is mainly used as a flame-retardant thermal insulation material having excellent thermal insulation effect, sound absorption and durability, but this is a structure in which single fibers are irregularly overlapped and laminated. Touched by the glass fiber terminal contact to the surface, the touch is tinged, short fibers of the aggregate surface are broken and detached and transferred to the worker's clothes, etc., which may cause temporary itching, and the short fibers are collected and laminated to form a plate-like aggregate. When used as a binder (phenol), phenol resin has a problem that can cause environmental pollution.

Unlike the single fiber of such a single component, in the two-component glass fiber produced by integrally spinning two-component molten glass having different coefficients of thermal expansion, the thermal expansion coefficient between the two components is different and the degree of shrinkage is different, resulting in a spring shape. However, self crimp, which has an irregularly curved shape, is expressed, so that fibers are entangled with each other to form a bulk without using a separate binder in the process of forming a bulk. When it is made of aggregates, it has excellent resilience and soft touch.

In order to make such two-component glass fiber, a process is required in which the two components can be fused at high temperature without mixing, which is a core technology of the high-speed centrifugal radiation method, which is generally used to manufacture single glass single fiber. By appropriately changing the structure of the spinner, the aforementioned two-component glass fibers can be produced and productivity can be increased.

1 is a cross-sectional view showing a state of use of a conventional two-component glass fiber manufacturing spinner, in which two molten glasses 2a and 2b of different components melt-fed and supplied from a separate melting furnace 1 are supplied to a supply pipe 3. When the spinner 7 is supplied to each of the spinners 7 below, the spinner 7 is rotated at a high speed by driving a rotary shaft 12 while the spinner 7 is heated to a predetermined temperature by the burner 13 to spin the spinner 7. The molten glass (2a, 2b) supplied to it flows outward by centrifugal force and is radiated to the glass fiber (15), and the continuous spinning glass fiber (15) is the high-pressure air of the high-pressure air jetting device (14) installed on the outer edge side. By being bent downward by the same time while being drawn and cooled, the dropping to the conveying device 16 is shown to be transferred to the post-work process.

FIG. 2 is a longitudinal sectional view of a conventional two-component glass fiber manufacturing spinner, in which two molten glass 2a and 2b of different components supplied through supply pipes 3a and 3b are respectively formed on the inner wall 6 of the spinner 7. Is fed directly to the bottom plate 4 through the upper and inner walls 6 and the rotary shaft 12 of the 'v' shaped separation plate 8 radially installed between the outer wall and the outer wall 5, One side of the molten glass (2a) is guided to the bottom of the separation plate 8 through the through hole 11 formed in the inner wall (6) is pressed to the outer wall (5) side and the other side molten glass (2b) is the upper portion of the separation plate (8) The glass fiber 15 through the orifice 10 while falling to the outer wall (5) is pushed toward the outer wall (5) so that the molten glass (2a, 2b) on both sides of the guide groove (9) centered around the separator plate (8) It is shown to be emitted.

Such a conventional two-component spinner for manufacturing a glass fiber has a very complicated structure, which makes it difficult to manufacture the spinner, and also causes a problem of shortening the life of the spinner due to deformation due to high rotation speed under very strong centrifugal force.

The present invention is to solve the conventional problems as described above, by simplifying the shape of the spinner to a cylindrical shape and remove the longitudinal partition to minimize the number of partition walls to facilitate the manufacture of the spinner and minimize the possibility of deformation of the spinner It is to provide a spinner for producing a two-component glass fiber.

In order to achieve the above object, the present invention is an inner spinner having two or more separate supply holes in the partition wall and the outer wall in the horizontal direction in order to fuse the two-component molten glass having different thermal expansion coefficients to each other and spun into one strand, It has a feature consisting of two spinners having a plurality of '외' shaped grooves on the inner wall and a V- or Y-shaped orifice on the outer wall.

Hereinafter, described in detail by the accompanying drawings of the present invention.

As shown in FIGS. 3 to 5, two molten glass 22a and 22b of different components melt-fed from the separate melting furnace 21 are supplied to the spinner 27 below through the supply pipe 23, respectively. When the spinner 27 is driven by a separate power source, the rotary shaft 50 rotates at a high speed so that the molten glass 22a and 22b supplied to the spinner 27 flow outward by centrifugal force to the glass fiber 35. The spinning and continuous spinning glass fiber 35 is bent downward by the high-pressure air of the high-pressure injection device 34 installed on both sides and at the same time falling to the transfer device 36 while being stretched and cooled to be transferred to the post-work process. It is shown.

It shows that the rotation shaft 50 is coupled to the center of the bottom surface of the second body 48 in which the feed holes 46 are formed so as to cross each other.

Here, the supply hole 46 should have various angles of inclination for even distribution to the upper and lower sides, but if the angle range is too large or too small, the smooth supply of the molten glass (22a, 22b) is not made The amount supplied to each of the supply holes 46, the deviation is not possible to produce a good quality glass fiber 35, the angle range is preferably set to 20 ~ 90 ° with respect to the center.

Figure 5 is a schematic diagram showing another embodiment of the spinner for producing a two-component glass fiber according to the present invention, the hook piece 52 which is held on the escape stop 42 of the second body 48 is projected downward The first body 40 ′ with an open lower portion is shown to surround the outer edge of the second body 48.

Referring to the use state of the present invention as follows.

As shown in FIGS. 3 to 5, the spinner 27 rotates at a high speed by the rotational force of the rotation shaft 50 rotated from a separate power source, so that centrifugal force is generated, and thus the spinner 27 is supplied to the spinner 27. The molten glass 22a, 22b is strongly radiated to the glass fibers 35 of several strands through the orifice 30 by the centrifugal force acting radially, wherein the high-pressure air injection device 34 installed on both sides is high pressure The glass fiber 35 is bent downward and stretched and cooled by injecting air into the air, so that the shrinkage deviation due to the difference in thermal expansion coefficient is generated between the molten glass 22a and 22b on both sides, so that the glass fiber 35 is twisted. It has a magnetic crimping property such as being bent in a twisted shape or bent in a spring shape, and when it is collected and molded into a certain shape, it is possible to be entangled between fibers without using a binder. It will be able to be molded in this way.

As described above, the present invention allows the molten glass of two components having different components to be spun into a single strand, and thus has a magnetic crimping property upon cooling, making it easy to form into a certain form without using a binder, and of course, the structure of the spinner. It is easy to manufacture by simplifying, and it is possible to prevent deformation due to high speed rotation, which has the effect of extending the life of the spinner.
