Abstract
Description
본 발명은 연근해 해안에서 양식하여 수확하는 글 등, 패각류의 활용에 관한 것으로, 패각류를 활용하여 여러 가지 형태를 가진 고체의 제조물(예: 건축용 블록, 보도블록, 인공 어초 등)를 생산하기 위한 방법과 그 제조물에 관한 것이다.The present invention relates to the use of shellfish, such as articles harvested from offshore coasts, to produce a variety of solid products (eg, building blocks, sidewalk blocks, artificial reefs, etc.) using shellfish. A method and a preparation thereof are provided.
일반적으로 양식 혹은 자연서식 등을 통하여 채취되는 패각류는 육상에 방치되거나 그대로 해안에 버려져 악취와 온갖 병균과 벌레들의 서식처가 되어 주변환경을 오염시키고 있을 뿐 아니라 인근 주민들의 질병발생 등 위생에 위험을 초래하고 있으며 이로 인하여 해양자원을 감소시키고 있으나 패각류를 원료하는 분야는 화공약품, 화장품 특정작물의 비료, 양계장용의 보조사료 등으로 극히 제한되어 있다.Shellfish, which are usually collected through farming or natural habitats, are left unattended on land or abandoned on the shore, becoming a habitat for odors and all kinds of germs and bugs, polluting the surrounding environment and risking health problems such as the occurrence of diseases of nearby residents. Although it is reducing marine resources, the field of shellfish raw materials is extremely limited to chemicals, fertilizers for certain crops, and supplementary feed for poultry farms.
따라서 그 소모량이 극히 미미함으로 수질과 해안오염 등을 방지하기에는 역부족임은 물론 대부분을 자원으로 활용하지 못하고 있는 실정이다.Therefore, the consumption is so small that it is not enough to prevent water quality and coastal pollution, and most of them do not utilize as a resource.
본 발명의 목적은 상기와 같은 문제점을 해소하기 위하여 패각류를 분쇄한 패각분말(도 3)과 점토광물(도 4)를 주원료로 하여 이를 상온에서 혼합공정(1)을 거쳐 목적하는 형태로 성형하거나 소결(2)하고 건조(3) 후 소성(4)하여 제조하는 고체의 제조물(예: 건축용 블록, 보도블록, 인공어초 등)을 완성하는 방법의 제공과 그 관련 제조물을 생산하기 위한 것이다.An object of the present invention is to form the desired shape through the mixing step (1) at room temperature as a main raw material to the shell powder (Fig. 3) and clay mineral (Fig. 4) pulverized shells in order to solve the above problems Or to provide a method for completing a solid product (eg, building blocks, sidewalk blocks, artificial reefs, etc.) to be produced by sintering (2), drying (3), and then firing (4) and to produce related products thereof.

After sintering (2) and drying (3), it is put in a kiln or a heating furnace and fired (4) to complete a solid product (Fig. 1). Detailed descriptions are provided as providing the technology to be made.
연체동물 패각의 성분 및 비율은 탄산칼슘( CaCO3)이 주성분이고 인산칼슘 [Ca3(PO4)2]이나 탄산마그네슘( MgCO3) 등이 소량 함유되어 있으며 무기물의 함량비는 종에 따라 약간의 차이는 있으나 탄산칼슘은 89∼99%, 인산칼슘은 1∼2 %, 탄산마그네슘은 극히 소량이 함유되어 있는데 각 성분의 대체적 성질은 ①탄산칼슘은 무색의 결정 또는 백색 고체로, 물에는 잘 녹지 않으며 비중 2.93, 약 900℃에서 분해되어 이산화탄소를 발생하고 생석회를 얻을 수 있고, ②인산칼슘은 인산의 삼칼슘염. 인산삼칼슘, 제삼인산칼슘이라고도 하며 녹는점 1670℃, 비중 3.14이며 비료와 영양제로 사용되거나, 에나멜이나 유리의 제조에도 사용된다. ③탄산마그네슘은 무색의 결정 또는 분말로, 비중 3.073이다. 물에 약간 녹고, 이산화탄소를 함유하는 물에는 중탄산마그네슘 [ MgCO3+CO2+H2O →Mg( HCO3)2] 이 되어 녹는다.The composition and proportion of mollusk shells is mainly composed of calcium carbonate (CaCO 3 ) and small amounts of calcium phosphate [Ca 3 (PO 4 ) 2 ] or magnesium carbonate (MgCO 3 ). However, calcium carbonate is 89 ~ 99%, calcium phosphate is 1 ~ 2%, and magnesium carbonate is contained in a very small amount. The alternative properties of each component are: ① Calcium carbonate is a colorless crystal or white solid, which is good for water. It does not melt and decomposes at specific gravity 2.93, about 900 ℃ to generate carbon dioxide and get quick lime. ② Calcium phosphate is tricalcium salt of phosphate. It is also called tricalcium phosphate and tricalcium phosphate. It has melting point of 1670 ℃ and specific gravity of 3.14. It is used as a fertilizer and nutrient or in the manufacture of enamel or glass. (3) Magnesium carbonate is colorless crystals or powders with a specific gravity of 3.073. Slightly soluble in water, and dissolved in water containing carbon dioxide Magnesium bicarbonate [MgCO 3 + CO 2 + H 2 O → Mg (HCO 3 ) 2 ].
점토광물이라 함은 점토를 구성하는 주성분 광물의 총칭으로서 규산염광물이 대부분이고 점토란 ①가소성이 있고 ②미세한 입자로 되어 있고 ③600℃ 이상으로 빨갛게 가열하면 굳어지는 3가지 성질을 가지고 있으며 일반적으로 입자 지름 2㎛ 이하의 것을 말하는 바 주성분인 규산염광물은 천연으로 산출되는 규산염. 조암광물로서 지각의 대부분을 차지하며 지구내부·우주공간의 고체물질로서 자연계에 널리 분포하는 고용체로서, Ca2+, Mg2+ ·Fe2+ 의 상호치환, Al3+ ·Fe3+, Na+과 K, OH-과 F- 등의 치환에 의해 조성이 복잡하게 되어 있다.Clay mineral is a general term of the main component minerals that make up clay, and most of silicate minerals are clay. ① Clay is composed of plasticity and ② fine particles. The silicate mineral which is a main component is a silicate produced naturally. It is a solid rock mineral that occupies most of the earth's crust as a coarse mineral, and is a solid substance widely distributed in the natural world as a solid substance in the earth and outer space. The mutual substitution of Ca 2 +, Mg 2 + · Fe 2 +, Al 3 + Fe 3 +, Na + And the composition is complicated by substitution of K, OH- and F-.
이러한 패각류와 점토광물의 상기와 같은 성질을 이용하여 패각분말(도 3)을30%에서 90% 정도의 양과 15%내외의 함수율을 가진 점토광물(도 4)을 10%에서 70% 가량의 비율로 혼합(도 2, 1)하여 목적하는 용도에 적합한 형상으로 성형 또는 소결(2)한 후 요업분야의 도자기나 기와, 흙벽돌 등을 제조하는 방법과 같이 건조(3)하여 소성용 가마 또는 가열로에 넣고 최종가열온도를 600℃에서 1350℃ 사이로 하여 4시간 이상 가열하여 소성(4)하면 점토광물(도 4)의 대부분을 차지하는 규산염광물에 포함된 여러 가지 성분이 녹아서 패각분말(도 3)의 입자를 에워싸거나 그러한 성분 중 화학반응으로 결합하여 굳어지게 되므로 고체로 소결된 완제품(도 1)이 제조되게 되는 것이다.Using the above properties of shellfish and clay minerals, the shell powder (Fig. 3) may contain about 30% to 90% of clay mineral (Fig. 4) having a water content of about 15% and about 10% to 70%. After mixing (Fig. 2, 1) at a ratio and forming or sintering into a shape suitable for the intended use (2) and drying (3) as in the method of manufacturing ceramics, tiles, earth bricks, etc. Put in the furnace and the final heating temperature is 600 ℃ to 1350 ℃ heated for more than 4 hours and calcined (4) when the various components contained in the silicate mineral that occupies most of the clay mineral (Fig. 4) melt shell shell (Fig. 3 The solid particles are sintered or solidified by enclosing the particles of the solid state or by chemical reaction among such components (FIG. 1).
이상에서 상술한 바와 같이 본 발명은 패각분말과 점토광물을 혼합하여 고체의 제조물을 제조하게 하므로 패각류를 대량으로 활용할 방법을 제공하여 자원화함으로서 ①패각류로 인하여 유발되는 각종 환경오염을 방지할 수 있을 뿐 아니라 ②세멘트로 제조되어지는 유사 관련 제품을 생산하게 됨으로 해당 제품의 원가를 저렴하게 하고 ③세멘트로 제조되어지는 제품의 수명은 대개 50년에서 100년 정도이나 점토광물로 제조되는 제품의 수명이 약 1000년 정도로 관련학계에서 추정하는 바 관련대체제품의 수명을 몇 배 이상 증가시키는 등의 효과가 있다.As described above, according to the present invention, the shell powder and clay minerals are mixed to prepare a solid product, thereby providing a method of utilizing shellfish in a large amount, thereby making it possible to prevent various environmental pollutions caused by shellfish. In addition, ② the cost of the product is reduced by producing similar related products that are manufactured by cement. ③ The lifetime of products manufactured by cement is usually 50 to 100 years, but the lifetime of products manufactured by clay minerals. This is estimated to be about 1000 years, which has the effect of increasing the life span of a related product by several times.
