Abstract
Description
본 발명은 무균열내열자기소지및 유약조성물에 관한 것으로, 특히 도자기의 본체를 이루는 소지(素地)는 완전 자화(磁化)되어 도자기 흡수율이 제로(zero)되어 일반도자기처럼 주방식기로 사용하는데 전혀 불편함이 없도록 한다.The present invention relates to a crack-free heat-resistant magnetic material and glaze composition, in particular, the body constituting the main body of the porcelain (완전 地) is completely magnetized (磁化) is zero dissipation rate of the porcelain (zero) is inconvenient to use as a kitchenware like a general ceramic There should be no bins.
일반적인 도기재 가열조리용기나 구이판은 내열성이 높고,가열과 냉각을 반복 수축성이 적어야만 직화나 전자레인지등에 의한 조리시 균열이 가지 않기 때문에 내열성소지를 사용하고 있다.In general, ceramic cooking vessels and roasting plates have high heat resistance and have low heat shrinkage and repeated shrinkage in heating and cooling.
일반적인 내열도자기의 소지원료로는 고령토나 점토, 산청토,페타라이트등의 무기물질을 혼합반죽한 소지를 가마에서 1150℃도 1300℃범위의 고열로 소성한 내열도자기를 제조하는것이 일반적이였다.As a subsidiary material for general heat-resistant ceramics, it was common to manufacture heat-resistant ceramics fired at a high temperature in the range of 1150 ° C to 1300 ° C in kilns mixed with inorganic materials such as kaolin, clay, acid blue soil, and ferrite.
상기와 같은 내열도자기를 초벌구이한 후, 0.5% 노르말 농도값을 갖는 게르마늄 졸 90%와 염화철 약 2%,염화니켈 약 6%,염화코발트 약 1%, 염화동 약 1%를 혼합교반한 고농축복합금속용질액에 담궜다 꺼내서, 약 1240℃로 재벌구이하는 방식이나, 초벌구어낸 내열자기에 엽장석57-77중량%, 활석 2내지 8중량%, 칼리장석과 석회석의 혼합물 10중량%, 알루미나와 규석의 혼합물 3중량% 등을 가미한 유약을 도포한후 재벌구이하는 방식이 있었다.After highly roasting the above-mentioned ceramics, the highly concentrated composite metal was mixed and stirred with 90% germanium sol having a concentration of 0.5% normal, about 2% iron chloride, about 6% nickel chloride, about 1% cobalt chloride, and about 1% copper chloride. Soaked in solute solution and roasted at about 1240 ° C, or bakelite 57-77% by weight, talc 2 to 8% by weight, 10 to 10% by weight of a mixture of califeld and limestone, and alumina and silica After applying a glaze with a mixture of 3% by weight, etc., there was a method of roasting chaebol.
위와 같은 방식에 있어서, 상기와 같은 유약을 발라 건조시켜 재벌구이 하기전에 유약에서 균열현상(crazing)이 발생하는 경향이 있어서, 완성된 내열자기의 표면균열로 인해 조리시 음식물이 도자기 표면에 흔적이 남는 현상이 발생한다.In the above manner, the glazing tends to occur in the glaze before drying the glaze by applying the glaze as described above, and the food is not traced on the surface of the porcelain during cooking due to the surface crack of the completed heat-resistant magnetic. The remaining phenomenon occurs.
이에 본 발명은 내열도자기를 이루는 소지(素地)를 완전 자화(磁化)시켜 도자기 흡수율이 제로(zero)시켜 일반도자기처럼 주방식기로 사용하는데 전혀 불편함이 없도록 하고자 한다.Therefore, the present invention is to completely magnetize the possession of the heat-resistant ceramic (素 地) to zero the absorption rate of ceramics (zero) so that there is no inconvenience to use as a kitchen tableware as a general ceramic.
또한, 도기재 가열조리용기나 구이판과같이 내열성이 높고,가열과 냉각을 반복 수축성이 적고, 직화나 전자레인지등에 의한 조리시 균열이 가지 않는 무균열내열자기 유약조성물을 제공하고자 한다.In addition, it is to provide a crack-free heat-resistant magnetic glaze composition that is high in heat resistance, such as porcelain heating cooking vessel and roasting plate, low shrinkage of heating and cooling, and does not crack when cooking by direct heating or microwave oven.
도 1은 본 발명에 따른 자기의 일실시 제조공정도1 is a manufacturing process diagram of one embodiment of the present invention
상기와 같은 목적을 이루기 위하여,이하 본 발명의 일실시 구성을 상세히 알아보면 다음과 같다.In order to achieve the above object, the following describes one embodiment of the present invention in detail.
실시예1.Example 1
본 발명에 따른 무균열내열자기 소지조성물의 최적조성비로는 수차례의 시험을 거친 결과 아프리카 짐바브웨산 엽장석(petalite) 65중량%, 활석 5중량% , 회색점토 30중량%의 소지원료혼합물에 의한 제품이 가장 안정성을 보였다.Optimal composition ratio of the crack-free heat-resistant magnetic holding composition according to the present invention was tested by several times as a result of a small support mixture of 65% by weight of African Zimbabwean petalite, 5% by weight of talc, 30% by weight of gray clay. The product showed the most stability.
상기, 실시예에서 조성물에서 엽장석을 65중량% 이상으로 조성하면, 내열성은 증가하나, 소지의 가소성(plasticity)이 떨어져, 생산중에 성형공정에서 불량이 많이 발생한다.In the above embodiment, when the feldspar is 65 wt% or more in the composition, the heat resistance is increased, but the plasticity of the substrate is lowered, and a lot of defects occur in the molding process during production.
활석의 경우에는 5중량% 첨가하면, 소성온도가 낮아지고 제품의 강도가 떨어져 제품의 질적저하를 갖어온다.In the case of talc, the addition of 5% by weight lowers the firing temperature and lowers the strength of the product, resulting in a decrease in product quality.
회색점토의 양을 증가시키면 생산중 성형공정에서 좋은 결과를 기재할수는 있으나, 제품의 내열성이 떨어져 제품의 질적저하를 가져온다.Increasing the amount of gray clay may give good results in the molding process during production, but the heat resistance of the product is lowered, which leads to a decrease in the quality of the product.
상기와 같은 소지로 생산된 내열자기의 유약조성물로는 아래와 같다.Glaze composition of the heat-resistant magnetic produced by the above possession as follows.
실시예2.Example 2.
엽장석 73중량%, 활석 16중량%, 흑색점토 5중량%, 석회석 6중량%의 유약이 가장 좋은 유약조성물 인데, 위 조성물중 엽장석의 양을 증가하면 내열성은 증가하나, 내화도가 높아져 소성온도가 높아지고 생산비용이 증가하여 생산성의 불합리를 초래한다.Glaze of 73% by weight of feldspar, 16% by weight of talc, 5% by weight of black clay, and 6% by weight of limestone is the best glaze composition.Increasing the amount of feldspar in the above composition increases the heat resistance, but increases the fire resistance and the firing temperature. Higher and production costs increase, resulting in unreasonable productivity.
석회석과 활석의 양을 감소하면 유약의 내화도가 높아지고 석회석과 활석의 양이 증가하면 유약의 내화도가 낮아져 제품의 질이 불합리 하게 된다.Reducing the amount of limestone and talc increases the fire resistance of the glaze, while increasing the amount of limestone and talc reduces the fire resistance of the glaze, resulting in unreasonable product quality.
상기에서, 흑색점토는 시험중에 항상 5중량%로 고정시킨 상태에서 시험을 진행하였는데, 이는 5중량% 이하로 떨어지면 유약의 제반 물성이 나빠져 생산성이 저하되고, 5중량% 이상을 취하게되면 내열성이 현저하게 저하된다.In the above, the test was conducted in a state where the black clay is always fixed at 5% by weight during the test, which falls below 5% by weight of the overall physical properties of the glaze deteriorates, and the productivity is lowered, and when it takes 5% by weight or more, Significantly lowered.
상기와 같이 제안된 소지로로 내열자기를 만들어,초벌구어낸 제품에 유약을바르고 제품을 생산하는 것은 일반도자기의 생산방식과 동일하지만, 참고적으로 설명하면, 도 1에 도시된바와 같이, 본 발명에 따른 혼합조성물인 소지 조성물로 제품을 성형한후, 재차 정형과정을 거쳐, 850℃에서 초벌구어내, 본 발명에 따른 유약조성물로 시유시켜 화공(畵工)한후, 1250℃로 산화소성해 완제품으로 출하 포장하는 것이다.Making heat-resistant magnetic with the proposed base as described above, to apply glaze to the first baked product and to produce the product is the same as the production method of general ceramics, but for reference, as shown in Figure 1, the present invention After molding the product with a composition according to the mixed composition according to the present invention, after the shaping process again, at 850 ° C. in the first boil, the oil composition of the glaze composition according to the present invention, after the chemical process (oxidation) fired at 1250 ℃ finished product Will be shipped in packaging.
상기와 같이 구성된 본 발명의 작용효과로는 본 발명은 내열도자기를 이루는 소지(素地)와 유약조성물로 제조된 내열도자기는 완전 자화(磁化)되어 도자기 흡수율이 제로(zero)되어, 일반도자기 처럼 주방식기로 사용하여도,가열조리용기나 구이판과같이 내열성이 높고,가열과 냉각을 반복 수축성이 적고, 직화나 전자레인지등에 의한 조리시 균열이 가지 않는 무균열내열자기소지및 유약조성물로서 매우 유용한 발명인 것이다.As a working effect of the present invention configured as described above, the present invention is a heat-resistant ceramic made of a base (素 地) and glaze composition forming a heat-resistant ceramic is completely magnetized (磁化) zero absorption of porcelain (zero), the kitchen like a general ceramic Even when used as a tableware, it is very useful as a non-cracked heat-resistant magnetic base and glaze composition that has high heat resistance, such as a heating cooking container or a baking board, has low repetitive shrinkage of heating and cooling, and does not crack when cooking by direct heating or microwave oven. will be.
