Description

Orifice of spinner for making two-component glass fiber

The present invention is to produce a glass fiber by spinning molten glass, the two-component glass fiber to make a two-component glass fiber by simultaneously spinning two molten glass having different chemical components through one orifice It relates to an orifice structure of a manufacturing spinner.

In general, the aggregate that collects single-fiber single-fiber glass fiber is mainly used as a heat-insulating material with excellent heat insulation effect, sound absorption and durability without burning well, but short fibers are irregularly overlapped and stacked. As it is formed, it is sensation due to surface contact, short fibers on the surface of the aggregate are detached and transferred to clothing of workers, which can cause temporary itching, and when used to form a plate-like aggregate by collecting the short fibers Binder 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 molten glass having different coefficients of thermal expansion, the coefficients of thermal expansion between the two bonded components are different from each other. The difference in shrinkage between the two bonded glass is caused by the self crimp, which has a spring shape or irregularly curved shape, so that the fibers are entangled with each other to form an aggregate. It can be made into a certain form without using a binder. In order to make these two-component glass fibers, a process is required in which the two components can be fused at high temperatures without being mixed with each other, which is a key technology of the high-speed centrifugal separation method, which is generally used for the production of single-component short fibers. Properly modifying the structure of the spinner and orifice can produce the aforementioned two-component glass fibers and can increase productivity.

On the other hand, Figure 1 and Figure 2 shows a spinner for producing a conventional two-component glass fiber, the molten glass (2a, 2b) of different components that do not mix with each other even at high temperatures spinner (1) formed with an orifice (4) The partition 6 is installed to flow to the outer wall of the, and the shape of the orifice 4 is also divided into the partition 6 between the two molten glass (2a, 2b) of different components on one side of the orifice ( Through 4) at the same time coming out to show that they are fused to each other.

At this time, the shape, length, position, diameter, and the like of the orifice 4 formed on the spinner 1 has a great influence on general physical properties such as the length and thickness of the fiber. Particularly, in the bicomponent glass fiber, Because it determines the ratio of the two molten glass is fused, it has a big influence on the winding property, the orifice formed in the spinner to produce the two-component glass fiber is mainly used V or Y type orifice, V type The orifice is made by making holes in two different directions with appropriate angles at the same position on the outer wall of the spinner, and the Y-shaped orifice is formed by drilling two holes at an angle where they can meet each other at a point inside the outer wall of the spinner outer wall. Later, the orifice is completed by machining the hole from the outside to the exact point where the two holes from the inside meet. The.

In order to form an orifice in the conventional two-component glass fiber manufacturing spinner as described above, the orifice shape cannot be directly determined by the eye as well as the complicated process described above. Because of the small size, errors caused by machines or operators during processing may significantly change the shape of the orifice. Also, in the case of the V-type orifice, which is relatively easy to process, the two molten glass may be bonded to each other as compared to the time of fiberization. Since the time is extremely short, the two molten glass is not effectively bonded, and some molten glass is fiberized as a single component and is made of short fiber without bending and has a problem of sometimes failing to obtain a desired product having flexibility.

The present invention is to solve such a conventional problem, it is easy to process when forming the orifice of the spinner for producing a two-component glass fiber and that the two molten glass is mixed through the smooth bonding and contact surface when the molten glass of different components It is an object of the present invention to provide an orifice structure of a spinner for manufacturing a two-component glass fiber that can be minimized.

In order to achieve the above object, the present invention is formed on the outer wall of the spinner, partitioned by a separator plate, the orifice consisting of the first inlet, the second inlet, and the outlet, the orifice is the first inlet and the second inlet integral By means of an outlet having a predetermined radius of curvature 'Funnel shape.

In the present invention, the opios is formed by the outlet having a constant height ' 'Funnel shape.

6 is a partially enlarged cross-sectional view for explaining a bonded portion of a two-component glass fiber manufactured using an orifice according to the present invention, wherein the molten glass (2a, 2b) having a different thermal expansion coefficient is the first inlet 10a and The joining portions of the two molten glasses 2a and 2b are mixed with each other in the case of being made of one strand of glass fiber through a triangular or funnel-shaped orifice 10 composed of two inlets 10b and outlets 12 and 12 '. Rather, it is bonded at a constant ratio (about 50:50).

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

As shown in FIGS. 3 to 6, the orifice 10 is formed at regular intervals along the circumference of the body portion 16 of the spinner 1, and is formed in a long hole or a circular shape and formed on the separator plate 14. A first inlet 10a and a second inlet 10b partitioned by the second inlet, and having a circular outlet 12 having a predetermined radius of curvature on the outside. To form an orifice 10 having a funnel shape.

In this state, when two molten glasses 2a and 2b having different thermal expansion coefficients are supplied to the spinner 1, the molten glass 2a is supplied to the first inlet 10a by the separating plate 14 and the other molten glass 2b is supplied to the second inlet 10b. At this time, the spinner 1 is in a state of being rotated by being given a rotational force by a separate driving means (not shown).

Therefore, the supplied molten glass (2a, 2b) is radiated to the outside through the orifice 10 by centrifugal force, it is bonded to each other through the orifice (10) to produce one strand of two-component glass fibers.

In this way, in the manufactured glass fiber, the coefficient of thermal expansion between the two molten glass is different from each other, so that the shrinkage during cooling causes a difference in the degree of shrinkage during cooling. It can be entangled so that it can be made into a certain form without using a separate binder in forming the aggregate.

Meanwhile, the funnel shape of the orifice 10 has a constant height at the outlet 12. When the shape of the funnel is shaped, it is possible to lengthen the time that the two molten glass 2a and 2b can be bonded to each other, so that the fusion between the two molten glass 2a and 2b is performed reliably, so that It is possible to prevent the production of short fibers of the component.

According to the present invention, by forming a two-component glass fiber manufacturing spinner, a triangular orifice having a first and second inlet and a circular outlet in the form of a long hole, and a funnel orifice having a constant height at the outlet, The processing to form the orifice is easy, as well as making the manufacturing process very easy, there is an effect that can reduce the defect of the product.
