원적외선을 방사하는 고강도 황토벽돌의 제조방법{Manufacturing process of yellow earth block to radiate far-infrared ray}Manufacturing process of high-strength ocher bricks emitting far-infrared rays {Manufacturing process of yellow earth block to radiate far-infrared ray}

본 발명은 원적외선을 방사하는 고강도의 황토벽돌의 제조방법에 관한 것이다.The present invention relates to a method for producing high strength ocher bricks that emit far infrared rays.

종래에는 황토를 적량의 물로 반죽하여, 보강재로서 짚을 썰어 넣어 성형기에서 황토벽돌를 만들고 건조하여 제조하여 사용하고 있다.Conventionally, ocher is kneaded with an appropriate amount of water, and straw is cut as a reinforcing material to make ocher bricks in a molding machine, and dried and manufactured.

원래 흡수성이 약하여 쉽게 젖어 부서지는 관계로 내장재에만 사용이 가능하고, 외벽재로 사용할 수 없는 저품위품질의 것이다.Originally, due to its weak absorbency, it is easily wetted and broken, so it can be used only for interior materials and is of low quality that cannot be used as exterior wall materials.

이와같이 비에 젖으면 쉽게 흡수하여 부서지기 쉬우므로 내벽에만 사용이 가능하다. 강도가 약하여 보강재로서 짚이나 갈대류를 사용하여 초가집이나 가축의 우리에 적합한 것이 현실정이었다.Thus, when wet with rain, it is easily absorbed and brittle, so it can be used only on the inner wall. Because of its low strength, it was practical to use straw or reed as a reinforcement and to fit thatch or herd cages.

이러한 황토 자체는 고기능성의 특성이 있으나 고품질 제품은 생산되지 못했고, 최근 그 특성을 살려 현대화하여 이용할 수 있는 새로운 기술이 요구되고 있 다. 특히 원적외선광이 방사되어 인체에 아주 유익한 작용을 하고 있다. 그러나 이러한 특성은 충분히 활용되고 있지 못한 것이 현 실정이다. 그러므로 이러한 특성을 최대한 활용하려면 규산칼슘수화물로 합성 경화시켜 고기능성의 황토벽돌로 사용할 있도록 하려는데에 본 발명의 목적이 있다.The loess itself has high functional properties, but high quality products have not been produced, and recently, new technologies that can be used by modernizing them are required. In particular, far-infrared light is radiated, which is very beneficial to the human body. However, these characteristics are not being fully utilized at present. Therefore, it is an object of the present invention to be used as a high-functional ocher brick by synthetic curing with calcium silicate hydrate in order to take full advantage of these properties.

천연산의 황토는 무진장하게 매장되어 있고 또한 원적외선광을 방사하여 인체 건강에 유익한 바, 이러한 특성을 최대한 활용하여 새로운 고기능성의 무기건재개발로 건축의 내,외장재로서 내구성이 있고 원적외선을 방사하는 황토벽돌을 제조하고자 한다.Natural loess is buried indefinitely, and it is beneficial to human health by radiating far infrared rays. It is durable and emits far infrared rays as interior and exterior materials of construction by developing new high-functional inorganic building materials by making full use of these characteristics. To manufacture bricks.

원적외선광을 방사하는 황토벽돌이 고강도를 갖고 내흡수성이 강한 내구성의 황토벽돌을 제작하고자 경화재료로서 슬래그분말과 고강도촉진제로서 석고와 석회를 가하여 증기함에서 습기양생하면 유효하게 사용할 수 있는 높은 강도를 나타내고 그 특성을 발휘할 수 있도록 한다.The ocher brick that emits far infrared rays has high strength and strong absorption resistance so as to make durable ocher brick with high strength that can be effectively used when cured in steam by adding slag powder as hardening material and gypsum and lime as high strength accelerator. Display and exhibit its characteristics.

황토는 실트크기의 가는 입자들로 구성되어 있으며 탄산칼슘에 의해 고결되어 있는 인황색의 퇴적물이다. 광물조성은 50-60% 석영을 포함하고 있으며, 실리카, 알루미나, 산화철, 산화칼슘, 마그네시아 등이며 기타 미량의 산화물로 구성되어 있다.Loess is composed of silt-sized fine particles and is a yellowish-yellow deposit deposited by calcium carbonate. Mineral composition contains 50-60% quartz, silica, alumina, iron oxide, calcium oxide, magnesia, etc., and other traces of oxides.

또한 옛날부터 짚을 잘게 썰은 보강재를 넣어 경화체(벽돌이나 벽체재)로 사용되어 왔으나, 새로운 재료에 밀리고 새로운 제품의 개발이 없어 사장되고 있는 실정이었다. 최근 원적외선광을 95%까지 방사하고 있는 것에 착안하여 새롭게 각광을 받고 있다.In addition, the straw has been used as a hardening body (brick or wall material) by stiffening chopped straw, but it has been lost due to the lack of new products and development of new products. In recent years, it has been spotlighted on the fact that it emits up to 95% of far infrared rays.
