Description

견운모를 사용한 원적외선을 방사하는 상토 골재의 제조 방법{A PROCESS OF THE MANUFACTURING BED SOIL AGGREGATE RADIATING FAR-INFRARED RAYS USING SERICITE}A manufacturing method of the top soil aggregate which radiates far infrared rays using a mica {A PROCESS OF THE MANUFACTURING BED SOIL AGGREGATE RADIATING FAR-INFRARED RAYS USING SERICITE}

본 발명은 견운모를 사용한 원적외선을 방사하는 경량의 무기질 상토 골재의 제조 방법에 관한 것으로, 더욱 상세하게는, 견운모를 미분쇄한 다음, 소석고를 가하고 물을 첨가하여 슬러리를 만든 후, 알루미늄 금속 분말을 첨가하여 발포시키고, 상압 온도에서 경화한 후 조분쇄하여 소정 크기의 경량의 무기질 상토 골재를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing a lightweight inorganic clay aggregate that emits far-infrared rays using villi, and more particularly, after grinding the villi, adding calcined gypsum and adding water to form a slurry, The present invention relates to a method for producing lightweight inorganic clay aggregate having a predetermined size by adding, foaming, curing at atmospheric pressure and coarsely pulverizing.

종래에는 펄라이트, 질석 등을 경량의 무기질 상토 골재로서 사용하였다. 상기 펄라이트는 진주암, 흑요암 또는 이에 준하는 성질을 갖는 암석을 분쇄한 다음 소성 팽창시켜 제조하고, 또 상기 질석을 팽창성 운모를 소성 팽창시켜 제조한다.In the past, pearlite, vermiculite, and the like were used as lightweight inorganic clay aggregates. The pearlite is prepared by pulverizing and then calcining rock having pearlite, obsidian or similar properties, and preparing vermiculite by calcining and expanding expandable mica.

상기 펄라이트 및 질석은 한국 공업 규격에도 명시되어 있으며, 이러한 경량의 무기질 상토 골재는 공식적으로 사용되고 있다. 그러나, 국내 자원의 고갈과 국내산 원료의 저품위로 인하여 상기 상토 골재를 제조하기 위해 그 원료가 계속해서 수입되고 있으며, 그로 인한 외화 손실이 막대할 뿐 만 아니라, 유기질 원료의 수입까지 합산하면 연간 500억원 규모에 이르고 있는 실정이다.The perlite and vermiculite are also specified in Korean Industrial Standards, and these lightweight inorganic clay aggregates are officially used. However, due to the depletion of domestic resources and the low quality of domestic raw materials, the raw materials are continuously imported to manufacture the above-mentioned aggregates, and as a result, foreign currency losses are enormous. It is reaching the scale.

또한, 종래의 경량의 무기질 상토 골재는 제조 공정에서 1000℃ 내외의 고온에서 소성 발포시켜야 하기 때문에, 에너지 다소비 공정으로서 원가 상승의 단점이 있다.In addition, since the conventional lightweight inorganic clay aggregate has to be foamed at a high temperature of about 1000 ° C. in the manufacturing process, there is a disadvantage of cost increase as an energy wasteful process.

따라서, 경량의 무기질 상토 골재의 대체 품목이 시급한 바, 이에 대한 대책으로서 국내에 매장되어 있는 천연 광물을 최대한 활용하려는 시도가 이루어지고 있다.Therefore, as an alternative to lightweight inorganic clay aggregates is urgent, an attempt has been made to make the most of natural minerals buried in Korea as a countermeasure.

종래 견운모는 주로 기계부품의 마모제, 화장품이나 약품의 증량제, 기계의 마모 방지제 도료의 혼합제로 사용되어 왔으나, 본 발명자들은 국내에 다량으로 매장되어 있는 견운모를 농업용 상토로 개발하여 농산물의 증산에 기여하기 위하여 현재 상토 골재로서 활용되고 있지 않은 원적외선을 다량 방사하는 견운모를 미분쇄한 후, 소성 발포 없이 저온 발포하고 양생시켜 경량의 무기질 상토 골재를 제조하는 방법을 제공하는 것을 목적으로 한다.Conventional biotite has been mainly used as a mixture of abrasives for machine parts, cosmetics or pharmaceuticals, and anti-abrasion paints for the machine. However, the present inventors have contributed to the production of agricultural products by developing biotite, which is stored in large quantities in Korea, as a top soil for agriculture. It is an object of the present invention to provide a method for producing lightweight inorganic clay aggregates by pulverizing mica that emits large amounts of far infrared rays, which are not currently utilized as clay aggregates, and then foaming and curing at low temperature without plastic foaming.

본 발명은 200 메쉬 이하로 미분쇄한 견운모 60 내지 80 중량%에 소석고 20 내지 40 중량% 및 60℃의 물 40 내지 60 중량%를 첨가하여 슬러리를 만든 다음, 발포제로서 알루미늄 분말 0.1 내지 0.5 중량%를 넣어 발포시키고, 상압 온도에서 경화시키는 것을 특징으로 하는 원적외선을 방사하는 경량의 견운모 상토 골재의 제조 방법인 것을 특징으로 한다.The present invention adds 20 to 40% by weight of calcined gypsum to 40 to 60% by weight of calcined gypsum and 40 to 60% by weight of water at 60 ° C, and then 0.1 to 0.5% by weight of aluminum powder as a blowing agent. It is characterized in that it is a method of manufacturing a lightweight biotite topsoil aggregate that emits far-infrared rays, characterized in that it is foamed and cured at atmospheric pressure.

또한, 본 발명은 상기 견운모 상토 골재의 제조 방법에서 견운모의 50%를 석비례로 대체하여 제조하는 견운모 상토 골재를 제조하는 방법인 것이다.In addition, the present invention is a method for producing a biotite top aggregate prepared by replacing 50% of the villus in the method of producing a biotite top aggregate by Seok proportional.

이하 본 발명을 보다 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명에서 사용되는 견운모, 소석고 및 석비례의 화학 성분은 다음과 같다.The chemical components of the biotite, calcined gypsum and Seokbyol used in the present invention are as follows.

본 발명에서 사용되는 견운모는 천연 매장량이 무한하고, FT-IR 분광계를 이용한 흑체 대비 측정 결과, 식물체 내에서 물과 영양분과 탄소동화작용을 하는데 가장 중요한 식물성장 광합성 광선인 원적외선 측정치(방사 파장 5 내지 20㎛)은 95%이고, pH는 8.42 이다. 본 발명에서는 우선 상기의 천연 견운모를 200 메쉬 이하로 미분쇄한다.The biotite used in the present invention has infinite natural reserves, and a far infrared ray measurement value (radiation wavelength 5 to 5) which is the most important plant growth photosynthetic ray for the carbon activating action with water and nutrients in the plant as a result of the black body comparison using the FT-IR spectrometer. 20 μm) is 95% and the pH is 8.42. In the present invention, the above-mentioned natural mica is first pulverized to 200 mesh or less.

이어서, 상기 미분쇄 된 견운모 60 내지 80 중량%에 소석회 20 내지 40 중량% 및 60℃의 물 40 내지 60 중량%를 첨가하여 슬러리를 형성한다. 상기 소석고는 그 형상을 유지하고, 식물성장조건에 적합한 pH 6 내지 7의 범위를 벗어나지 않도록 하기 위해서 사용된다.Subsequently, 20 to 40% by weight of hydrated lime and 40 to 60% by weight of water at 60 ° C are added to 60 to 80% by weight of the pulverized mica. The calcined gypsum is used to maintain its shape and not to fall outside the range of pH 6 to 7 suitable for plant growth conditions.

상기와 같이 형성된 슬러리에 발포제로서 알루미늄 분말 0.1 내지 0.5 중량%를 첨가한 다음 상압 온도에서 경화시킨다. 여기서, 알루미늄 분말은 견운모와 소석고가 존재할 때 발포제로서 경량 상토를 제조하게 된다. 경량 상토의 재료 특성은 다공성이 가장 좋게 되는데 그 이유는 공기가 잘 통하게 되는 통기성이 있고, 물이 잘 빠지는 배수성이 있어야 하기 때문이다.0.1 to 0.5% by weight of aluminum powder is added to the slurry formed as described above as a blowing agent and then cured at atmospheric pressure. Here, the aluminum powder is to produce light weight clay as a blowing agent in the presence of the mica and calcined gypsum. The material properties of the lightweight topsoil have the best porosity because the air is well ventilated and the water drains well.

pH는 6 내지 7의 범위가 식물 성장 조건에 적합하기 때문에 지나친 산성 토양은 토양 개량제가 필요한 바, 이에 따라 pH를 적정 범위로 하기 위해서 상기에서 사용된 견운모의 50%를 석비례를 대체하여 사용하는 것도 가능하다. 상기 석비례는 FT-IR 분광계를 이용한 흑체 대비 측정 결과, 원적외선 측정치(방사 파장 5 내지 20㎛)은 93%이고, pH는 6.40 이다.Since pH ranges from 6 to 7 are suitable for plant growth conditions, excessive acidic soils require soil modifiers. Thus, 50% of the sorghum used above is used in place of Seobyeol in order to bring the pH to an appropriate range. It is also possible. Said proportionality is the result of the black body measurement using the FT-IR spectrometer, the far infrared ray measurement value (radiation wavelength 5-20 micrometers) is 93%, and pH is 6.40.
