CONSTITUTION: A rod of a diameter more by 1.5mm than an outer diameter of a sleeve is made using polyvinyl chloride material. The rod is inserted in a kneading material of a gel state formed by kneading a plaster, and a plaster where an engraved frame(12) is formed. Suspension is fabricated by inputting ceramic(18), organic dispersant, ball media(28) and water in a pot and rotating inputted materials. The suspension is put in the engraved frame(12) formed in the plaster, and a predetermined time elapses. Ceramic particles(18) are melted and adhered on a wall of the frame(12) by a capillary pressure, so that a melted and adhered layer is formed. If the melted and adhered layer has a predetermined inner diameter, remaining suspension are discharged and the plaster is dried during a predetermined time. After a time, the melted and adhered layer becomes a dried layer(22) with the dried layer(22) spaced apart from the frame(12). A sintered material is formed by drying and sintering the dried layer(22) formed in the frame(12).

Description

광페롤용 슬리브의 제조방법Manufacturing method of optical ferrol sleeve

본 발명은 광페롤용 슬리브의 제조방법에 관한 것으로서, 특히 슬리브를 제조하기 위한 성형틀이 형성된 석고의 모세관 압력을 이용하여 슬리브를 간단하게 제조할 수 있는 광페롤용 슬리브의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a sleeve for an optical ferrol, and more particularly, to a method for manufacturing a sleeve for an optical ferrol, which can be easily manufactured using a capillary pressure of a gypsum with a forming mold for producing a sleeve.

통상적으로, 광섬유의 접속을 위한 광페롤은 초정밀 가공이 되어있는 슬리브에 의해 정확한 정렬(align)이 이루어지며, 상기 슬리브는 사출성형 방법 또는 압출성형 방법으로 제조된다. 이들 두 방법은 모두 유기 바인더의 유동성을 이용하여 인위적인 압력을 가해줌으로써 필요한 형상을 성형하는 방법이다.Typically, the optical ferrol for the connection of the optical fiber is precisely aligned by a sleeve which is subjected to ultra precision processing, and the sleeve is manufactured by an injection molding method or an extrusion molding method. Both of these methods are methods for shaping the required shape by applying artificial pressure using the fluidity of the organic binder.

상기 슬리브 제조방법 중에서 압출성형법은, 방아간에서 떡을 뽑아내는 것과 동일한 방법의 공정으로 슬리브와 동일형상의 긴 성형체를 만들어서 필요한 길이만큼 자른 후에 상기 성형체를 가공을 해서 완제품의 슬리브를 생산하는 방법이다. 즉, 상기 슬리브의 재료인 세라믹 파우다와 바인다를 각각 가공한 후에 상기 세라믹 파우다와 바인다를 진공으로 혼합한 후, 압출 성형한다. 이어서 압출에 의해 형성된 성형체를 오븐(oven)을 이용하여 강제적으로 건조시킨 후에 다시 상기 성형체를 약 200℃∼300℃로 에이징(aging) 한다. 그후, 상기 성형체를 약 1500℃로 소결(sintering) 한다. 이어서 상기 성형체를 길이방향 및 내,외경을 가공한 후에 다시 슬릿(slit) 가공함으로써 완제품의 슬리브는 제조되어진다.In the sleeve manufacturing method, the extrusion molding method is a method of producing a sleeve of a finished product by processing the molded body after making a long molded product of the same shape as the sleeve and cutting it to the required length by a process similar to that of removing the rice cake from the mill. That is, after processing the ceramic powder and the binder of the material of the sleeve, respectively, the ceramic powder and the binder are mixed in a vacuum and then extruded. Subsequently, the molded body formed by extrusion is forcibly dried using an oven, and then the molded body is aged again at about 200 ° C to 300 ° C. Thereafter, the molded body is sintered at about 1500 ° C. The sleeve of the finished product is then manufactured by slitting the molded body after the longitudinal direction and the inner and outer diameters are processed again.

그리고, 상기 슬리브를 제조하는 다른 방법으로는, 정해진 형상의 틀에 고정도의 유동성을 가지는 원료를 유입시켜서 틀의 형상과 동일한 슬리브를 얻어내는 가압식 성형방법인 사출성형법이 있다. 상기 사출성형법은 슬리브의 재료인 세라믹과 약 50%의 바인다를 가공한 후에 상기 원료와 바인다를 진공으로 혼합한 후, 사출 성형한다. 그후 사출에 의해 형성된 성형체를 약 500℃∼700℃로 열처리(탈지)하여 바인다를 제거한다. 이어서 바인다가 제거된 성형체를 소결(sintering)한 후에 상기 성형체를 길이방향 및 내,외경을 가공한다. 그후 상기 성형체를 슬릿(slit) 가공함으로써 완제품의 슬리브는 제조되어진다.As another method of manufacturing the sleeve, there is an injection molding method, which is a pressure molding method in which a raw material having high fluidity is introduced into a mold having a predetermined shape to obtain a sleeve having the same shape as the mold. In the injection molding process, after processing about 50% of the binder and the ceramic material of the sleeve, the raw material and the binder are mixed in a vacuum, followed by injection molding. Thereafter, the formed body formed by injection is heat treated (degreased) at about 500 ° C to 700 ° C to remove the binder. Subsequently, after sintering the molded body removed from the binder, the molded body is processed in the longitudinal direction and the inner and outer diameters. The sleeve of the finished product is then manufactured by slitting the molded body.

그러나, 상기와 같은 슬리브의 제조방법인 압출성형법과 사출성형법은 원료가공시에 첨가되는 바인다를 제거하기 위하여 열처리 공정이 추가되기 때문에 제조공정이 복잡함과 동시에 제조공정이 증가되며, 상기 세라믹과 바인다를 서로 혼합시키기 위하여 혼련기, 성형을 위한 사출기 또는 압출기, 바인다 제거를 위한 탈지로가 별도로 추가되므로서 상기 슬리브 제조를 위한 설비의 증가로 제품의 원가가 상승하고, 또한 상기 세라믹 입자에 유동성을 부여하기 위하여 바인다 첨가 및 진공혼랍공정이 꼭 필요하기 때문에 별도의 원료가공공정이 추가되며, 상기 슬리브의 성형을 위하여 고가의 금형을 별도로 제작함으로써 제품의 원가가 상승하여 타사와의 경쟁력이 떨어지는 문제점이 발생하였다.However, the extrusion method and the injection molding method of the sleeve manufacturing method as described above, because the heat treatment process is added to remove the binder added to the raw material processing, the manufacturing process is complicated and the manufacturing process is increased, the ceramic and the binder In order to mix with each other, a kneading machine, an injection machine or an extruder for molding, and a degreasing furnace for removing a binder are added separately, thereby increasing the cost of the product and increasing fluidity of the ceramic particles by increasing the equipment for manufacturing the sleeve. In order to add a binder and vacuum mixing process, a separate raw material processing process is added, and by manufacturing an expensive mold separately for forming the sleeve, the cost of the product increases and thus the competitiveness of other companies is inferior. .

상기와 같은 문제점을 해결하기 위하여 본 발명의 목적은 슬리브를 제조하기 위한 성형틀을 석고로 제작하므로 슬리브의 제조공정을 현저히 단축시킬 수 있는 광페롤용 슬리브의 제조방법을 제공하는데 있다.In order to solve the above problems, an object of the present invention is to provide a manufacturing method of a sleeve for optical ferrol that can significantly shorten the manufacturing process of the sleeve because the molding mold for manufacturing the sleeve is made of gypsum.

본 발명의 다른 목적은 슬리브를 석고의 모세관 압력으로 간단하게 제조할 수 있는 광페롤용 슬리브의 제조방법을 제공하는데 있다.It is another object of the present invention to provide a method for producing a sleeve for an optical ferrol that can be produced simply by capillary pressure of gypsum.

본 발명의 또 다른 목적은 슬리브의 원가를 현저히 감소시킬 수 있는 광페롤용 슬리브의 제조방법을 제공하는데 있다.Still another object of the present invention is to provide a method for manufacturing a sleeve for an optical ferrol that can significantly reduce the cost of the sleeve.

상기와 같은 목적을 달성하기 위하여 본 발명은 광페롤용 슬리브의 제조방법은,In order to achieve the above object, the present invention provides a method for manufacturing a sleeve for an optical ferrol,

First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals are used for the same components, even if displayed on different drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

본 발명에 따른 슬리브의 제조방법을 설명하면, 먼저 도 1에 도시된 바와 같이 염화비닐(polyvinyl chloride:이하 PVC라함) 재질을 이용하여 슬리브 26의 외경보다 직경이 1.5mm 만큼 큰 로드(rod)를 만든다. 이어서 상기 PVC 성형물인 로드를 석고가루를 반죽하여 형성된 젤(gel) 상태의 반죽물속에 넣은 후에 음각의 성형틀 12가 형성된 석고 10을 제작한다. 그후, 세라믹 18과 유기물 분산제 30과 볼 메디아 28 및 물을 용기(pot) 14에 넣은 후에 상기 용기 14를 2시간에서 4시간 동안 회전시켜 평균 입경이 약 0.5μm가 되도록 현탁액(suspension) 16을 제조한다. 이때 상기 세라믹 18은 지르코니아 재질 또는 알루미나 재질 또는 지르코니아와 알루미나가 서로 혼합된 재질로 형성되고, 또한 상기 유기물 분산제 30은 상기 세라믹 입자 간의 인력을 방지하기 위하여(세라믹 입자를 서로 뭉치는 것을 방지하기 위하여) 수소이온농도(PH)가 산성 또는 염기성 값을 가진다. 즉 상기 유기물 분산제 30은 PH 7∼8의 범위를 벗어난 값을 가지고 제타 포텐셜(zeta potential) 값을 최하로 가진다. 그리고 상기 용기 14에는 약 40WT%∼60WT%의 세라믹 18이 투입되어져 상기 물과 혼합되고, 상기 용기 14 부피의 약 30%∼50%의 볼 메디아 28이 상기 용기 14에 투입된다.Referring to the manufacturing method of the sleeve according to the present invention, first, as shown in Figure 1 using a polyvinyl chloride (polyvinyl chloride: PVC) material is a rod (rod) larger by 1.5mm in diameter than the outer diameter of the sleeve 26 Make. Subsequently, the rod, which is a PVC molded product, is placed in a gel dough formed by kneading plaster powder, and then a gypsum 10 having a negative mold 12 is formed. Thereafter, ceramic 18, organic dispersion 30, ball media 28, and water were placed in a pot 14, and then the vessel 14 was rotated for 2 to 4 hours to prepare a suspension 16 such that the average particle diameter was about 0.5 µm. do. At this time, the ceramic 18 is formed of a zirconia material or an alumina material or a material in which zirconia and alumina are mixed with each other, and the organic dispersant 30 is to prevent attraction between the ceramic particles (to prevent agglomeration of the ceramic particles from each other). Hydrogen ion concentration (PH) has an acidic or basic value. That is, the organic dispersant 30 has a value outside the range of PH 7 to 8 and has the lowest zeta potential value. Then, about 40 WT% to 60 WT% of ceramic 18 is introduced into the vessel 14, and mixed with the water, and about 30% to 50% of the ball media 28 of the volume of the vessel 14 is introduced into the vessel 14.

그후, 상기 현탁액 16을 석고 10의 내부에 형성된 성형틀 12에 부운 후에 약 5분∼20분간의 침적시간을 가진다. 이어서 상기 성형틀 12에 충진되어 있는 세라믹 입자 18은 도 2a에 도시된 바와 같이 석고의 고유성질인 모세관 압력에 의해 상기 성형틀 12의 벽면에 융착되어져 융착성형층 20이 형성된다. 이때 상기 세라믹 18은 모세관 압력에 의해 성형틀 12의 벽면에 융착되면서 현탁액 16의 수분이 줄어들게 되는데 이를 방지하기 위하여 상기 현탁액 16을 성형틀 12에 자동적으로 공급하는 공급탱크를 설치할 수 있다.Thereafter, the suspension 16 is poured into a mold 12 formed inside the gypsum 10 and has a deposition time of about 5 to 20 minutes. Subsequently, the ceramic particles 18 filled in the mold 12 are fused to the wall surface of the mold 12 by capillary pressure, which is a property of gypsum, as shown in FIG. 2A to form a fusion molding layer 20. At this time, the ceramic 18 is fused to the wall surface of the mold 12 by capillary pressure to reduce the moisture of the suspension 16. In order to prevent this, a supply tank for automatically supplying the suspension 16 to the mold 12 may be installed.

그후, 일정시간 경과 후에 상기 융착성형층 20의 내경이 일정한 크기(약 2.5mm)가 되면 상기 성형틀 12에 남아있는 현탁액 16을 쏟아내고 상기 성형틀 12가 형성된 석고 10을 약 5분이내 동안 뒤집어 놓은 후에 적정시간 동안 건조시킨다. 그후 상기 성형틀 12의 내부에 형성된 융착성형층 20의 내경이 균일화(leveling)가 되면 상기 석고 10을 바로 놓는다. 이때 상기 융착성형층 20은 도 2에 도시된 바와 같이 상기 성형층 12와 소정의 갭(gap) 28을 유지하면서 건조성형층 22로 형성된다. 그후 상기 성형층 12의 내부에 형성된 건조성형층 22를 적정시간 동안 건조하고 이어서 소결(sintering)하여 도 2c에 도시된 바와 같이 소결체 24로 형성한다. 그후 상기 소결체 24에서 두껍게 형성된 양측 돌출부 22a,22b를 절단한 후에 길이방향으로 가공한다. 이어서 상기 양측 끝이 절단된 소결체 24를 슬릿가공하면 도 2d에 도시된 바와 같이 완제품의 슬리브 26이 제조되어진다.After that, when the inner diameter of the fusion molding layer 20 reaches a constant size (about 2.5 mm), the suspension 16 remaining in the mold 12 is poured out and the plaster 10 on which the mold 12 is formed is turned over for about 5 minutes. After drying for a suitable time. Then, when the inner diameter of the fusion molding layer 20 formed inside the mold 12 is leveled, the gypsum 10 is directly placed. In this case, the fusion molding layer 20 is formed as a dry molding layer 22 while maintaining the molding layer 12 and a predetermined gap 28 as shown in FIG. 2. Thereafter, the dry molding layer 22 formed in the molding layer 12 is dried for a suitable time and then sintered to form a sintered body 24 as shown in FIG. 2C. Thereafter, both side protrusions 22a and 22b thickly formed in the sintered body 24 are cut and then processed in the longitudinal direction. Subsequently, when the sintered body 24 cut at both ends is slitted, the sleeve 26 of the finished product is manufactured as shown in FIG. 2D.
