본 발명은 용융유리를 방사(紡絲)하여 유리섬유를 제조함에 있어서, 서로 다른 화학성분을 갖는 2종의 용융유리를 동시에 방사시킴으로서 2성분을 갖는 장섬유(長纖維)를 제조할 수 있도록 한 2성분 유리섬유의 제조방법 및 제조장치에 관한 것이다.In the present invention, in the manufacture of glass fibers by spinning the molten glass, it is possible to produce long fibers having two components by simultaneously spinning two kinds of molten glass having different chemical components A method and apparatus for producing a two-component glass fiber.

일반적으로 단섬유(短纖維)의 유리섬유를 집면하여서 되는 유리섬유 집합체는 불에 잘 타지 않으면서 보온단열 효과와 흡음성 및 내구성이 우수하여 보온단열재로서 주로 사용되고 단섬유가 불규칙하게 중첩·적층 구성되므로서 표면 접촉에 의한 촉감이 따갑고, 또 표면상의 단섬유가 부스러지면서 탈리되어 작업자의 의복 등에 전이(轉移)되므로서 일시적 가려움증을 유발할 수 있으며 단섬유를 집면·적층시켜 판상의 집합체를 성형코져 할 때 결합제(Binder)로서 환경 유해물질인 페놀수지를 사용하므로서 생기는 문제점을 갖게 되었던 것이다.In general, glass fiber aggregates by collecting single-fiber glass fibers are mainly used as thermal insulation materials because they have excellent thermal insulation effect, sound absorption and durability without being burned well, and short fibers are irregularly overlapped and laminated. When it touches the surface, it feels tingling, and the short fibers on the surface are broken down and detached and transferred to worker's clothes, which can cause temporary itching. As a binder (Binder) has been a problem caused by using the environmentally harmful phenol resin.

본 발명은 이와같은 문제점을 해소하기 위하여, 2종의 용융유리를 일체로 방사하여 냉각시킴으로서 유리섬유가 자기권축성(SELF CRIMP)을 갖도록 하여 만들어진 유리장섬유를 일정 길이로 절단하게 되면 스프링형태로 말리게 되거나 꾸불꾸불한 형태로 굴곡되어 이를 적층하여 집합체를 형성시 별도의 결합제가 없이도 집합체를 형성할 수 있도록 한 것으로, 이를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.In order to solve the problem, the present invention is to cut the glass fiber made by having a glass fiber is self-stretching (SELF CRIMP) by cooling the two kinds of molten glass integrally and dried in a spring form When it is bent in a serpentine or serpentine form, it is laminated to form an aggregate to form an aggregate without a separate binder, which will be described in detail with reference to the accompanying drawings.

하나의 용해로에서 용융된 용융유리가 스로트와 피더를 경유하여 온도센서와 레벨스위치에 의해 온도 및 유량(流量)이 제어되면서 부싱의 오리피스를 통해 방사되어 장섬유를 제조토록 한 유리섬유의 제조방법 및 장치에 있어서, 부싱(4)을 중심으로 양측에 피더(3a)(3b)와 스로트(2a)(2b)로 연통되는 용해로(1a)(1b)를 대칭형으로 형성하고, 피더(3a)(3b)상에 온도센서(10a)(10b)와 레벨스위치(11a)(11b)를 설치하되, 오리피스(5)의 상면에 부싱(4)을 양분하는 분리판(9)을 오리피스(5)의 중심선을 지나도록 지그재그형으로 설치하며, 부싱(4)의 하방에는 일정간격을 두고 냉각기(6)와 구동로울러(7) 및 와인더(8)를 설치하므로서, 서로 다른 성분을 갖는 2종의 유리원료를 양측 용해로에 분리 투입하여 적정온도로 용융시키게 되면 용융유리는 스로트(2a)(2b) 및 피더(3a)(3b)를 경유하여 부싱(4)내로 진입하게 되고, 부싱(4)내로 진입된 서로 다른 성분의 용융유리는 분리판(9)에 의해 각 오리피스(5)의 ½에 해당하는 부분으로 방사되어 팁(5')을 통과하면서 용융유리의 점도에 의해 2가지 성분의 용융유리가 1가닥으로 합치되어 장섬유(f)로 방사되는 것으로, 장섬유(f)는 냉각기(6)를 통과하면서 냉각·경화되어 구동로울러(7)로 모아져 와인더(8)로 감아서 회수하게 되는 것이다.Method for producing glass fiber in which molten glass melted in one furnace is spun through orifice of bushing while temperature and flow rate are controlled by temperature sensor and level switch via throat and feeder. And in the apparatus, symmetrically forming melting furnaces (1a) and (1b) communicating with feeders (3a) (3b) and throats (2a) (2b) on both sides of the bushing (4). The temperature sensor (10a) (10b) and the level switch (11a) (11b) is installed on (3b), and the orifice (5) has a separating plate (9) bisecting the bushing (4) on the upper surface of the orifice (5). It is installed in a zigzag shape so as to pass through the center line of the bushing, and the cooler 6, the driving roller 7 and the winder 8 are provided at a predetermined interval below the bushing 4, thereby having two kinds of components having different components. When glass raw materials are separated into two melting furnaces and melted at an appropriate temperature, the molten glass is divided into throats 2a and 2b and feeders 3a and 3b. Entering into the bushing (4) via the molten glass of the different components entered into the bushing (4) is radiated by the separating plate (9) to the portion corresponding to ½ of each orifice (5) to the tip (5 ') The molten glass of two components is combined into one strand by the viscosity of the molten glass and passed into the long fiber f. The long fiber f is cooled and cured while being passed through the cooler 6 to be driven. Collected by the roller (7) will be collected by winding the winder (8).

도면중 미설명 부호 12는 내화 및 단열 기능을 갖는 벽체이다.In the figure, reference numeral 12 denotes a wall having fire and heat insulation functions.

이와같은 본 발명은 도면의 제1도 및 제2도에 나타낸 바와같이 서로 다른 성분을 갖는 2종의 유리원료를 양측 용해로(1a)(1b)에 각각 분리하여 투입한 후 용해로(1a)(1b)를 별도의 가열원을 이용하여 설정된 점도에 도달하도록 용융시키게 되면 용융된 유리는 스로트(2a)(2b) 및 피더(3a)(3b)를 경유하여 부싱(4)의 오리피스(5)를 통해 장섬유(f)로 방사되어 와인더(8)에 의해 별도의 드럼(도시하지 않음)에 권취·회수되는 것인데, 각 용해로(1a)(1b)에 투입되는 유리원료는 도면의 제3도 및 제4도에 나타낸 바와같이 분리판(9)에 의해 오리피스(5)를 2등분하여 양측에서 동시에 방사되므로서 도면의 제5도에 나타낸 바와같이 양측으로 2가지 성분을 갖는 장섬유(f)가 한개의 오리피스(5)당 한가닥씩 방사되는 것인바, 필요시 드럼에 권취된 장섬유(f)를 필요한 길이로 절단하여 사용하게 되는 것으로, 장섬유(f)를 약 50∼150mm 단위로 절단하게 되면 장섬유(f)는 후술하는 이유에 의해 도면의 제6도에 나타낸 바와같이 스프링 형태로 말리게 되거나 고리형 또는 꾸불꾸불한 형태로 굴곡되게 되므로서 이를 집면하여 일정형태의 집합체를 성형할 경우 별도의 결합제를 사용하지 않아도 성형이 가능함은 물론 성현후에도 표면이 탈리될 우려가 없으며 표면과의 접촉에 의한 촉감 또한 부드러워 시공을 편안하게 하는 것이다.In the present invention, as shown in FIGS. 1 and 2 of the drawings, two kinds of glass raw materials having different components are separately introduced into both melting furnaces 1a and 1b, and then each melting furnace 1a and 1b. ) Is melted to reach the set viscosity using a separate heating source, the molten glass passes through the orifice 5 of the bushing 4 via throats 2a, 2b and feeders 3a, 3b. It is spun into long fibers (f) through the winder (8) is wound and recovered in a separate drum (not shown), the glass raw material introduced into each melting furnace (1a) (1b) is shown in FIG. And long fibers f having two components on both sides, as shown in FIG. 5 of FIG. 5, by splitting the orifice 5 into two parts by the separator 9 as shown in FIG. Is spun one strand per one orifice (5), if necessary to cut the long fibers (f) wound on the drum to the required length When the long fibers f are cut in a unit of about 50 to 150 mm, the long fibers f are dried in the form of a spring as shown in FIG. As it is bent in a serpentine form, it is possible to mold it by collecting it and to form a certain type of aggregate without using a separate binder, and there is no fear of surface detachment even after manifestation, and the touch by the surface is also soft. It is to make construction comfortable.

여기에서, 장섬유(f)를 일정길이로 절단할 경우 제6도와 같이 다양한 형태로 굴곡되는 이유는 제5도에서와 같이 2가지 성분의 유리원료가 열팽창계수를 달리하므로서 가능케 된 것인데, 이는 열팽창계수가 큰쪽에서 열팽창계수가 작은 쪽으로 구불어지기 때문인바, 도면 제6도의 (a)와 같이 스프링 형태의 것을 얻기 위하여는 양측 성분의 열팽창계수차를 크게하면 가능한 것이고, (b)도와 같이 고리형태의 것을 얻기 위하여는 양측 성분의 열팽창계수차를 작게하면 가능한 것이며, (c)도와 같이 꾸불꾸불한 형태의 것을 얻기 위하여는 용융유리가 오리피스(5)를 통하여 방사된 후 냉각기(6)를 통과하기 직전에 장섬유(f)를 조금만 뒤틀리게 하여주면 장섬유(f)는 냉각기(6)를 통과하면서 뒤틀린 상태로 경화되므로서 가능하게 되는 것이다.Here, the reason why the long fiber (f) is bent in various forms as shown in Fig. 6 when cut to a certain length is made possible by the glass raw material of the two components as shown in Fig. 5 different thermal expansion coefficient, which is the thermal expansion This is because the coefficient of thermal expansion is bent from the larger coefficient to the smaller one. In order to obtain a spring form as shown in Fig. 6 (a), it is possible to increase the coefficient of thermal expansion of both components, and as shown in (b) It is possible to reduce the coefficient of thermal expansion of both components in order to obtain, and to obtain the shape of the sinusoidal shape as shown in (c), the molten glass is spun through the orifice 5 and then passed through the cooler 6. If the long fiber f is twisted just before, the long fiber f becomes curable in a warped state while passing through the cooler 6.

이상에서와 같이 본 발명은 열팽창계수가 서로 다른 2가지 성분의 유리원료를 동시에 방사하여 하나의 장섬유를 제조하므로서, 이를 필요 길이로 절단시 다양한 형태로 굴곡되므로 일정형상의 집합체를 성형함에 있어 별도의 결합제를 사용하지 않아도 성형이 가능하여 환경오염을 방지하게 됨은 물론 성형품을 취급·사용시 촉감이 부드러워 보다 나은 환경에서 시공을 할 수 있게 되는 등의 다대한 효과가 있는 것이다.As described above, the present invention manufactures one long fiber by simultaneously spinning two different glass raw materials having different thermal expansion coefficients, and thus, when cutting it to the required length, it is bent in various forms to separate the aggregates in a certain shape. It can be molded without the use of binders to prevent environmental pollution, as well as to soften the feel when handling and using the molded products, so that it can be constructed in a better environment.
