It heats uniformly and quickly without any joke to improve the taste of food, save energy, suppress the occurrence of soot, facilitate the removal, improve the hygienic and cosmetic decoration effect, and provide the direct cooking pot for cooking pot and tableware. There is a purpose.
종래에도 전통적인 뚝배기와 같은 오지그릇이 있으나, 다양한 조리에 적합하지 못할 뿐만 아니라 사용이 불편하며 열충격에 약하여 직화식으로 적당하지 못하며 외관상 장식을 다양하게 할 수 없는 결점을 면치 못하였다.Conventionally, there are crock bowls such as traditional earthenware pots, but they are not suitable for a variety of cooking, are inconvenient to use, and are not suitable for direct fire because they are weak to thermal shock, and have not been able to diversify the appearance.
본 발명은 이와 같은 문제점을 해결하기 위하여 세라믹의 적외선방사효과와 내열성을 응용하여 직화식도자기냄비를 창안한 것으로서, 이하 본 발명을 상세히 하면 다음과 같다.In order to solve the above problems, the present invention has been invented by directing ceramic pots by applying infrared radiation effect and heat resistance of ceramics.
본 발명은 전기 목적을 달성하기 위하여 점토(Al2O3Si2) 30%, 카오링(Al2O3SiO2·2H2O) 15%, 납석(Al2O34SiO2·H2O) 20%, 리튬장석(Li2OAl2O3·(SiO2) 35%를 용적비로 배합하여 6-l4μm으로 미분쇄한 원적외선방사세라믹배체를 탈철, 탈수, 토련하여 성형한 것을 1350℃이하에서 소성하여 소지를 형성하고 소지표면에 규산화합물(SiO2)의 유약을 도포하여 1100℃-1200℃에서 소성하고 전사처리한 원적외선방사세라믹으로 조성된 직화식도자기냄비제조법이다.The present invention is 30% clay (Al 2 O 3 Si 2 ), 15% kaoring (Al 2 O 3 SiO 2 · 2H 2 O), feldspar (Al 2 O 3 4SiO 2 · H 2 O) to achieve the electrical purpose 20% and 35% of lithium feldspar (Li 2 OAl 2 O 3 · (SiO 2 ) were blended in a volume ratio, and the pulverized far-infrared radioactive ceramic powder, which was pulverized to 6-l4μm, was dehydrated, dehydrated, and drilled at 1350 ° C. It is a direct ceramic pot manufacturing method which is composed of far-infrared radiation ceramics formed by applying a glaze of silicic acid compound (SiO 2 ) on the surface of the body and baking it at 1100 ℃ -1200 ℃.
본 발명의 작용효과를 설명하면 다음과 같다.Referring to the effects of the present invention.
본 발명의 조성범위는 점토(Al2O3SiO2) 30%, 카오링(Al2O3SiO2·2H2O) 15%, 납석(Al2O34SiO2·H2O) 20%, 리튬장석(Li2OAl2O3·8SiO2) 35%의 분립상접합체로서, 파장 6-14μm의 원적회선을 발생하는 것이고 그 화학성분은 Al2O3, SiO2, Li2으로서, 특히 점토, 석영, 장석 등 소지는 점토함유량이 증가하면 소성온도가 높아지고 소지를 미분화 할 수록 소성온도가 내려가는데 일반적으로 소성온도 1100℃ -1200℃면 고형화되나 축열보온효과를 얻기 위하여 소지체를 다공화 할 필요가 있어서, 본 발명에서는 소성온도를 1350℃로 하였다.Composition range of the present invention is 30% clay (Al 2 O 3 SiO 2 ), kaoring (Al 2 O 3 SiO 2 · 2H 2 O) 15%, feldspar (Al 2 O 3 4SiO 2 · H 2 O) 20%, Lithium feldspar (Li 2 OAl 2 O 3 · 8SiO 2 ) 35% granular phase conjugate, which produces a circular line with a wavelength of 6-14 μm and its chemical composition is Al 2 O 3 , SiO 2 , Li 2 , especially clay Firing temperatures such as quartz, feldspar, etc. increase the clay temperature, and the firing temperature decreases as the micronizes the dust. Generally, the firing temperature is solidified at the firing temperature of 1100 ℃ -1200 ℃. It is necessary to make the firing temperature 1350 ° C in the present invention.
본 발명에 있어서 원적외선방사세라믹분합체를 소성하여 소지로 한 것은 세라믹은 다공성으로서 열전도율이 낮고 열용량이 크므로 서서히 가열이 되고 발열에 시간이 걸려서 열 충격에 강하여 적합하고 보온성과 축열효과가 있어 에너지가 절약되며 복사열에 의하여 식품에 열을 직접 전달하여 농담없이 균일하게 가열함으로써 맛이 좋게 조리할 수 있기 때문이다.In the present invention, the far-infrared radiation ceramic mixture is calcined and possessed by ceramic, which is porous and has a low thermal conductivity and a large heat capacity, so it is gradually heated and takes time to generate heat, which is suitable for thermal shock, and has thermal insulation and heat storage effect. This is because the heat can be directly delivered to the food by radiant heat, and the food can be cooked satisfactorily by heating evenly.
본 발명에 의하여 제조된 도자기냄비가 직화방식으로 사용이 가능한 것은 원적외선 세라믹소지가 1350℃의 고온에서 소성되고 다공성이여서 내열성이 강하고 열전도율이 낮아 서서히 가열하여 열충격에 강할 뿐만 아니라 유약이 소지의 분압체인 장석, 석면, 카오링 등과 같은 규산화합물로서 열팽창률이 거의 같고 융점이 소지 보다 낮아서 잘 밀착됨으로써 유약이 소지의 팽창수축과 일치하여 열충격에 의하여 벗겨지고 균열이 생기거나 파괴되지 아니하므로 직화식으로 가능하다. 또한 이와 같은 유약은 세라믹제품이 액체와 가스를 흡수하지 못하도록 제품표면에 피복하기 위하여 사용되는 유리질의 불투과성재료로서 제품을 보강하는 동시에 표면을 빤질빤질하게 하여 물이나 화학물에 대한 저항성을 높여서 그을음의 발생을 억제하고 부착된 그을음의 제거를 용이하게 하는 작용을 한다.Pottery pot prepared by the present invention can be used by direct fire method, the far-infrared ceramic body is calcined at a high temperature of 1350 ℃ and is porous, which is heat resistant and has low thermal conductivity, so it is gradually heated and resistant to thermal shock and feldspar which is a partial pressure body of glaze. Silica compounds, such as asbestos and kaoring, have almost the same thermal expansion coefficient and have a lower melting point than that of the base, so that the glaze is peeled off by thermal shock in accordance with the expansion and contraction of the base, and thus it is possible to be directly fired. In addition, such glaze is a glassy impermeable material used to coat the surface of ceramic products to prevent the absorption of liquids and gases. It reinforces the product and makes the surface of the surface so as to increase the resistance to water and chemicals. It acts to suppress the occurrence of and to facilitate the removal of attached soot.
한편, 세라믹에는 항균작용을 하는 페라이트계라는 성분이 있어 산화를 방지하여 균의 번식을 억제하므로 매우 위생적인 것이다.On the other hand, ceramics have a component called ferrite, which has an antimicrobial effect, which is very hygienic because it inhibits the growth of bacteria by preventing oxidation.
이상과 같이 조성된 본 발명의 직화식도자기냄비는 열팽창계수가 4.3×10-6으로 낮추어짐으로써 열충격시험검사온도인 280℃-290℃를 초과하는 0-700℃에서도 견뎌내는 강한 내열성이 있고 열충격 후에 도자기 표면에서 납(Pb)과 카드륨(cd)이 각각 0.7%와 0.5%를 초과하지 아니하므로 심사기준 7%에 미달하여 안전하다.The direct cooking ceramic pot of the present invention prepared as described above has a low thermal expansion coefficient of 4.3 × 10 −6, and thus has a strong heat resistance and thermal shock resistance even at 0-700 ° C. exceeding the thermal shock test temperature of 280 ° C.-290 ° C. Later, lead (Cb) and cadmium (cd) do not exceed 0.7% and 0.5%, respectively, on the surface of ceramics.
