본 고안은 판유리 또는 유리그릇 등의 유리제품을 이온교환식 강화유리 제조법으로 처리하여 강화유리 제품을 얻기 위한 통전용 전극체(일명 : 전극)에 관한 것이다.The present invention relates to a current-carrying electrode body (aka: electrode) for obtaining a tempered glass product by treating a glass product such as a plate glass or a glass bowl with an ion exchange tempered glass manufacturing method.

강화유리제품을 제조하는 일반적방법은 풍냉법이며, 풍냉법 이후인 1960년에 이온교환식 강화유리제조법이 영국특허 제917388호로 발표 되었다.The general method of manufacturing tempered glass products is the wind-cooling method, and in 1960, after the wind-cooling method, the ion exchanged tempered glass manufacturing method was published in British Patent No. 917388.

이들 풍냉법과 이온교환법의 양자를 대비하면, 강화유리로서는 같으나 방법으로서는 현격한 차이가 있으며, 양자는 각기 산업적 특징이 상이하고, 각가가 장단점을 갖는 것으로 알려졌다(일본국요업협회발행 "세라믹스" 1977년 제4권 제297-305면 참조).In contrast to both the wind-cooling method and the ion exchange method, they are the same as tempered glass, but the method is remarkably different, and both are known to have different industrial characteristics and have advantages and disadvantages. ("Ceramics" issued by the National Association of Ceramic Industries 1977) 4, pp. 297-305).

이온교환식 강화유리제품의 제조에서는, 예를들면 질산칼륨으로 되는 전해질의 고체물층 또는 용융액층 또는 이들에 점토를 첨가하여 되는 전해질층을 강화처리될 유리제품의 양측면부에 균등히 피복하여 전해질층을 표착한 유리제품과, 이 전해질층의 양측표면에 대하여 합치 또는 포위하는 도전용전극체와를 직열 또는 병열로 배착한 다음 도전용전극체 상호간에 직류전기를 일정시간동안 통전하여 유리제품의 일측표면부 내의 약 40-80미크론의 깊이에까지 유리속의 Ma+이 K+이론으로 대치되게 함으로서 압축응력층을 일측표면에 형성시키는 제1단계처리를 하고 다음에는 유리제품의 타측표면에도 같은 두께 내의의 압축응력층을 형성시키는 제2단계처리를 수행함으로서 강화유리제품을 제조하는 것으로 되어 있다.In the production of ion exchanged tempered glass products, for example, an electrolyte layer is deposited by uniformly covering both sides of the glass product to be tempered with a solid material layer or a melt layer of an electrolyte made of potassium nitrate or an electrolyte layer obtained by adding clay thereto. A glass product and a conductive electrode body that coincides or surrounds both surfaces of the electrolyte layer are arranged in series or in parallel, and a DC electric current is supplied to the conductive electrode bodies for a predetermined time, so that approximately one surface of the glass product is applied. The first step of forming a compressive stress layer on one surface by replacing Ma + in the glass with a theory of K + to a depth of 40-80 microns, and then applying a compressive stress layer of the same thickness to the other surface of the glass product. It is supposed to produce tempered glass products by performing the second step of forming.

이와같이 처리하는 강화유리 제조법에서 사용하는 층상구조부는, 유리제품을 중심층으로 하고서 그 양측면부에 전해질층을 경유하여 전극층을 배설하고 직열 또는 병열로 되는 층상구조물을 형성한다. 그리고 전해질층인 질산칼륨층은 이온 교환의 단계에서는 응용층으로 형성시키는 바, 이 단계에서는 유리제품층에 대하여 전기전도의 균등화가 긴요하며 또 전해질층을 용융층으로 형성하므로 용융물이 자체중량으로 제2(b)도의 표시와 같이 유리제룸(2)의 하측으로 몰려서 몰림단락부(短絡部)(S)를 형성하여 무용의 단락통전만을 유리할뿐이고 이온교환에 소요되는 통전은 극단적으로 방해하는 폐단이 유발되는 것이다. 뿐만아니라 층상구조물의 상측부에는 전해질 없는 공백부(H)를 형성하여 이 공백부(H)의 유리부분은 이온교환의 작용이 폐색되는 폐단을 유발하는 것이다. (제2(b)도참조).The layered structure used in the tempered glass manufacturing method to be treated as described above forms a layered structure in which the electrode layer is disposed on both sides of the glass layer as a center layer via the electrolyte layer and is in series or parallel. The potassium nitrate layer, which is an electrolyte layer, is formed as an application layer in the step of ion exchange. In this step, equalization of electrical conductivity is essential for the glass product layer, and the electrolyte layer is formed as a molten layer. As shown in Fig. 2 (b), it is gathered to the lower side of the glass room 2 to form a swelling short section S, so that only the short circuit energizing of dance is advantageous, and the energization required for ion exchange is extremely obstructive. It is triggered. In addition, an upper portion of the layered structure is formed with an electrolyte-free void H, and the glass portion of the void H causes a closed end where the action of ion exchange is blocked. (See also section 2 (b)).

이와같은 폐단을 방지하기 위하여 종래에는 점토가 첨가된 전해질로 되는 용융층으로 구성하였던 것이다. 그러나 점토의 첨가량이 많을수록 몰림단락부(S)와 공백부(H)의 형성이 방지되는 반면, 점토의 첨가량을 증가함은 전기전도성을 불량화하는 폐단이 필연적으로 등반되는 것이다.In order to prevent such a closed end, it was conventionally composed of a molten layer of an electrolyte to which clay was added. However, as the amount of clay added increases, the formation of the slit shorts S and the space H is prevented, while increasing the amount of clay inevitably climbs a closed end that degrades electrical conductivity.

본 고안은 상술의 점을 감안하여, 가) 몰림단락부와 공백부의 형성을 방지하며, 나) 전기전도성을 강화처리 중인 유리제품의 모든 표면에 대하여 균등분포하는 전극체를 얻음에 의하여, 다) 이온교환식 강화유리제품법의 수행을 원활화 하는 전극체를 얻음에 목적을 두는 것이다.In view of the above points, the present invention provides the following: a) preventing the formation of plunging shorts and voids, and b) obtaining an electrode body that distributes evenly to all surfaces of the glass product undergoing electrical conductivity reinforcement. The objective is to obtain an electrode body that facilitates the performance of the ion exchange tempered glass product method.

본 고안을 첨부의 예시도에 따라 설명하면 다음과 같다.Referring to the present invention according to the accompanying drawings as follows.

망목의 크기가 섬세한 모세관집성분포형의 금속망체층 냐지 금속섬유집성체층 하나 이상으로 되는 금속제 통전성모세관집성층(5)을 공지의 전극체에 스포트응접 내지 밀접하여 되는 전극체(1)(1')를 형성하여, 이 전극체(1)(1')에 배착된 금속제 통전성모세관집성층(5)이 전해질용융물층(3) 또는 점토 혼합의 전해질용융물층(3)에 물림단락부(S)와 공백부(H)의 형성을 방지하고 강화처리 되는 유리제품(2)에 대한 통전을 균등화함을 특징으로 하는 이온교환식 강화유리제품 제조용 전극체이다.Metal mesh layer of a capillary tube component foam having a fine mesh size, or an electrode body (1) (1 ') in which a metal conductive capillary layer (5) consisting of at least one metal fiber aggregate layer (5) comprising spot contact or intimate contact with a known electrode body is formed. ), And the metal conductive capillary collecting layer 5 deposited on the electrode body 1, 1 'is attached to the electrolyte melt layer 3 or the electrolyte melt layer 3 of the clay mixture (S). The electrode body for producing an ion exchanged tempered glass product, characterized in that to prevent the formation of the void portion (H) and to equalize the energization of the glass product (2) to be tempered.

금속제 통전성모세관집성층(5)에서 금속제라 함은 금속세선제 또는 금속섬유제임을 지칭한 것으로 이금속세선 또는 금속섬유의 재료로는 내식성의 금속재류 예를들면 내식성스텐레스 또는 기타 공지의 내식성 금속재를 이용하는 것이다.In the metal conductive capillary-composite layer 5, metal refers to a metal thin wire or a metal fiber material. As a material of the fine metal wire or the metal fiber, corrosion resistant metal materials such as corrosion resistant stainless steel or other known corrosion resistant metal materials are used. .

첨부도면에서는 유리제품(2)과 금속제 통전성모세관집성층(5)과의 사이에 협삽되는 전해질용융물층(3)을 두껍게 표시하였으나, 이는 전해질용융물층(3)의 표시를 명백화하기 위한 것이며, 실재에 있어서는 이 전해질용융물층(3)의 두께는 금속제 통전성모세관집성층(5)의 모세관적흡인작용이 영향을 주는 범위의 두께로하는 것이다. 그리고 금속섬유집성체층으로 되는 금속제 통전성모세관집성층(5)에도 전해질용융물이 내포되나, 이는 도시하지 아니하고, 금속망체층으로 되는 금속제 통전성모세관집성층(5)만을 도시하였는바, 이는 금속제 통전성모세관집성층(5)의 표시를 명백화 함에 있다. 또 예시도에서는 금속제 통전성모세관집성층(5)을 구성하는 금속방체층은 한장만을 도시하였으나, 이는 망목의 크기 100멧슈보다 더 섬세한 금속망체를 여러장으로 하여 중첩밀착함이 바람직하다.In the accompanying drawings, the electrolyte melt layer 3 thickly interposed between the glass product 2 and the metal conductive capillary collecting layer 5 is thickened, but this is to clarify the display of the electrolyte melt layer 3, In reality, the thickness of the electrolyte melt layer 3 is such that the capillary suction action of the metal conductive capillary collecting layer 5 is affected. In addition, the electrolytic melt is also contained in the metal conductive capillary collector layer 5 made of the metal fiber aggregate layer, but this is not illustrated, and only the metal conductive capillary collector layer 5 made of the metal mesh layer is illustrated, which is a metal conductive capillary collector. It is in clarifying the display of layer 5. In addition, although only one sheet of metal shielding layer constituting the conductive capillary tube collecting layer 5 made of metal is shown, it is preferable that the overlapping contact is made of several sheets of metal mesh more delicate than the mesh size of 100 mesh.

본 고안의 전극체(1)(1')에는, 섬세한 금속망체층 또는 금속섬유집성체층 하나 이상으로 되는 금속제 통전성모세관집성층 (5)이 갖는 모세관적 흡인작용이, 예를 들면 질산칼륨의 용융물로 되는 전해질용융물층(3)또는 이 용융물에 점토를 혼합한 전해질용융물층(3)을 모든 방향에서 흡인하고서 밀착되는 것이다.In the electrode body 1 (1 ') of the present invention, the capillary suction action of the metal conductive capillary collection layer 5, which is one or more of a fine metal mesh layer or a metal fiber aggregate layer, is, for example, a melt of potassium nitrate. The melted electrolyte layer 3, or the melted electrolyte layer 3 in which the clay is mixed with the melt, is attracted and adhered in all directions.

그러므로 금속제 통전성모세관집성층(5)의 섬세한 다수의 모세관은, 전해질용융물층(3)의 모든 표면에 균등분포 되어서 전해질의 용융물 또는 점토 혼합의 전해질용융물을)종횡의 모든 방향에서 흡수 및 흡인하면서 금속제 통전성모세관집성층(5)으로 작용한다.Therefore, many delicate capillaries of the metal conductive capillary collecting layer 5 are evenly distributed on all surfaces of the electrolyte melt layer 3 to absorb and suck the melt of the electrolyte or the electrolyte melt of the clay mixture in all directions. It acts as an electrically conductive capillary collecting layer (5).

그러므로, 본 고안의 층상구조물전체를 제2(a)도와 같이 세워놓아도 제2(b)도에 표시한 하측의 몰림단락부(S)와 상측의 공백부(H)를 형성하는 폐단이 배제되며, 눕혀놓아도 몰림단락부(S)와 공백부(H)의 형성이 배제되는 것이다. 뿐만아니라 본 고안의 금속제통전성모세관집성층(5)의 재료는 금속세선 또는 금속섬유이어서 전기저항이, 적으므로, 이온교환식 강화유리 제조시에 긴요조건으로 되는 전기전도성이, 전해질용융물에 점토를 첨가하면 종래의 그것보다 크게 향상된다. 따라서 본 고안의 전극체(1)(1')에 배설된 금속제 통전성모세관집성층(5)에 의하여 유리제품에 대한 이온교환식 강화처리도 더 효과적으로 균등화된다. 그러므로 본 고안은 이온교환식 강화유리 제조법의 수행을 금속제 통전성모세관집성층(5)이 없던 종래의 그것보다 더 원활화 및 균등화 하는 효과를 유래하는 것이다.Therefore, even if the entire layered structure of the present invention is placed as shown in FIG. 2 (a), the closed end forming the lower short-circuit section S and the upper blank portion H shown in FIG. 2 (b) are excluded. Even if laid down, the forming of the shorting section (S) and the blank (H) is excluded. In addition, since the material of the metal conductive capillary collection layer 5 of the present invention is a thin metal wire or a metal fiber, the electrical resistance is low, and thus, electrical conductivity, which is a critical condition in the production of ion exchanged tempered glass, is added to the electrolyte melt. It is greatly improved than that of the conventional. Therefore, the ion exchange reinforcement treatment for glass products is also equalized more effectively by the metal conductive capillary collecting layer 5 disposed on the electrode bodies 1, 1 'of the present invention. Therefore, the present invention derives the effect of smoothing and equalizing the performance of the ion-exchange tempered glass manufacturing method than the conventional one without the metal conductive capillary collecting layer 5.
