본 발명은 석화석 가공방법에 관한 것으로, 보다 상세하게는 자연에서 채취된 석화석(石火石)을 적정입도로 선별하여 그 구성 요소중 철이나 유기질 등 이물질을 제거한 순수 성분만 잔류되게 하고 이후 정제와 건조를 거쳐 마련된 반가공 상태의 석화석을 원하는 색채로 착색하여 분말화 함으로써 건축물 또는 조형물의 외장 마감재 및 미술작품의 착색재료로 활용할 수 있게한 석화석 가공방법에 관한 것이다.The present invention relates to a petrified stone processing method, and more particularly, to select a petrified stone collected from nature with an appropriate particle size so that only pure components from which foreign substances such as iron or organic matter are removed remain and then purified. The present invention relates to a petrified stone processing method that can be used as a coloring material for an exterior finish of a building or a sculpture and a work of art by coloring and pulverizing a semi-processed petrified stone in a desired color through drying.

일반적으로, 인위적인 충돌에 의해 불꽃을 발생시키는 성질을 가진 석화석은 그 특성으로 인하여 성냥이나 라이터 등이 없었던 예전에는 부싯돌의 소재로 널리 사용되었으나, 오늘날에는 특별한 사용용도 보다는 잡석(雜石)으로 사용되고 있다.In general, petrified fossils that generate sparks due to artificial collisions have been widely used as flints in the past because they did not have matches or lighters, but today they are used as rubble rather than special uses. have.

즉, 상기 석화석은 다른 종류의 암석에 비해 강도가 약하고 조직이 치밀하지 않음으로써 건축자재나 조경재로 활용하기에 부적합하여 그 이용도가 상태적으로 미약하였다.In other words, the petrified stone is weaker than other types of rocks and is not suitable for use as a building material or a landscaping material because the structure is not dense.

본 발명은 상기 석화석의 취약점을 감안하여 안출한 것으로, 그 목적은 석화석의 특성을 활용하여 다양한 색상으로 착색이 가능하고 표면질감을 구비한 외장 마감재로 사용할 수 있는 석화석 가공방법을 제공하는 것이다.The present invention has been made in view of the weakness of the petrified fossil, the object of which is to provide a petrified stone processing method that can be used as an exterior finish having a surface texture and coloring in various colors by utilizing the characteristics of the petrified fossil. will be.

이러한 목적을 달성하기 위한 본 발명은, 자연에서 채취된 석화석을 과립상 또는 분말상으로 분쇄하여 입자의 크기가 약 10메쉬(mesh)를 통과할 정도로 선별하여 석화석분쇄물을 얻는 단계와, 상기 공정에 의해 선별된 석화석분쇄물을 순도가 55~65% 정도의 알카리(alkali)성 용액중에 투입하여 상온에서 약 24시간 정도 침지과정을 거친 후 세척을 통해 석화석분쇄물에 함유되었던 광물질이나 유기질 등의 이물질을 제거하는 단계와, 상기 이물질이 제거된 석화석분쇄물을 건조한 후 염색용 분해기에 수용된 원하는 색상의 염색액중에 잠길정도로 투입하여 30~50㎏의 압력하에서 약 24시간 정치시켜 염색하는 단계와, 상기 염색공정을 거쳐 착색된 석화석분쇄물이 응고된 후 분쇄기로 투입하여 분쇄를 함으로써 파우더 형태로 분쇄되어 분말 자체에 고유한 색상을 가진 착색재료로 완성함으로써, 간단한 공정으로 천연의 분말상 착색재료로 가공하여 건축소재 또는 미술품의 외장 마감재로 널리 활용할 수 있도록 한 것이다.In order to achieve the above object, the present invention comprises the steps of obtaining a petrified stone powder by pulverizing the petrified stone collected in nature into granular or powder form to the extent that the particle size passes through about 10 mesh (mesh), and The minerals contained in the petrified powders are added to the petrified powders selected by the process and then immersed in an alkaline solution having a purity of 55 to 65% for about 24 hours and then washed. The step of removing foreign matters such as organic matter, and drying the petrified stone powder from which the foreign matters are removed and immersed in the dyeing solution of the desired color accommodated in the dyeing disintegrator, and left to stand for about 24 hours under pressure of 30-50 kg. And the colored petrite powder obtained by the dyeing process is solidified and then put into a grinder to be pulverized to form a powder, which is inherent in the powder itself. By finishing with a coloring material having a, it is processed to a natural powdery coloring material in a simple process so that it can be widely used as an exterior finishing material of building materials or works of art.

이하, 본 발명의 석화석 가공방법을 공정에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the method for processing petrified stone of the present invention will be described in detail based on the process.

자연에서 채취된 석화석을 적정크기로 분쇄한 후 그 입자의 크기가 약 10메쉬(mesh) 이하를 통과할 정도의 과립상 또는 분말상 분쇄물을 선별한다.After crushing the petrified stone collected in nature to the appropriate size, the granular or powdery pulverized matter is selected to the extent that the particle size is about 10 mesh (mesh) or less.

상기 선별과정에서 규정크기보다 큰 덩어리는 재차 분쇄를 거치게 되는 데,분쇄물 입자의 크기가 10메쉬를 초과할 경우에는 다음의 착색공정에서 액상 염색제가 미세한 기공층을 갖는 석화석분쇄물에 제대로 침투되지 않음으로써 최종적으로 파우더 형태로 가공하였을 때 균일한 착색이 불가능한 문제점이 발생된다.In the screening process, the lump larger than the prescribed size is subjected to crushing again. If the size of the pulverized particles exceeds 10 mesh, the liquid dye dye penetrates properly into the calcite pulverized powder having a fine pore layer in the next coloring process. By not doing so, a problem arises in that uniform coloring is impossible when finally processed into a powder form.

상기 공정에 의해 규정 크기로 선별된 석화석분쇄물은 순도가 55~65% 정도의 알카리(alkali)성 용액중에 투입하여 상온에서 약 24시간 정도 침지과정을 거친 후 흐르는 물에서 세척을 함으로써 석화석분쇄물에 함유되었던 광물질이나 유기질 등의 이물질을 제거한다.The petrified pulverized material selected by the above size is put into an alkaline solution having a purity of 55 to 65%, and immersed in about 24 hours at room temperature, and then washed in running water. Remove foreign substances such as minerals and organic matter contained in the pulverized product.

상기 이물질이 제거된 석화석분쇄물은 그 내부조직의 함수율이 "0"이 될 때까지 건조시키게 되는데, 건조시간을 단축하고 건조효율을 높이기 위해 열풍건조기를 이용하여 220℃~250℃ 범위에서 48시간정도 건조를 하는 것이 바람직하다.The petrified pulverized material from which the foreign matter is removed is dried until the moisture content of the internal structure becomes "0". 48 in the range of 220 ℃ ~ 250 ℃ using a hot air dryer to shorten the drying time and increase the drying efficiency It is preferable to dry about time.

상기 여러 공정을 거친 석화석분쇄물은 소비자의 요구에 따라 착색하기 위한 염색공정을 거치게 되는데, 염색조검은 밀폐된 용기, 즉 분해기에 원하는 색상의 염색제를 주입하고 이에 석화석분쇄물을 잠길정도로 투입하여 30~50㎏의 압력하에서 약 24시간 정치시켜 염색을 한다.The petrified pulverized powder that has undergone the various processes is subjected to a dyeing process for coloring according to the demand of the consumer. The dyeing test is injected into a closed container, that is, a dyeing agent of a desired color in a decomposer, and immersed in the pulverized pulverized powder. Dye under a pressure of 30-50 kg for about 24 hours.

이때, 석화석분쇄물은 이물질이 제거된 상태이므로 그 조직 자체에 미세한 기공이 무수히 형성되어 있으므로, 높은 압력하의 염색액 중에서 염색액의 용입이 원활히 이루어 진다.At this time, since the petrified stone is in a state in which foreign substances are removed, numerous pores are formed in the tissue itself, so that the dye solution is easily infiltrated in the dye solution under high pressure.

염색시의 밀페된 분해기의 압력이 30㎏ 미만일 경우 분쇄물의 조직 내부의 중심점 까지 염색제의 혼입이 미흡하여 염색이 제대로 되지 않거나 원하는 색상보다 연하게 되고, 분해기의 압력이 50㎏ 이상으로 높게 될 경우 진한상태로 염색이되어 염색시 그 분해기의 내부압력을 적당하게 조절함으로써 동일 색상의 경우에도 그 농도를 조절할 수 있다.If the pressure of the sealed cracker during dyeing is less than 30 kg, the dye may not be mixed properly due to insufficient mixing of the dye to the center point of the inside of the pulverized tissue, and if the pressure of the cracker is higher than 50 kg, By dyeing in the state, the concentration of the same color can be adjusted by properly adjusting the internal pressure of the decomposer during dyeing.

상기 염색공정을 거쳐 착색된 석화석분쇄물이 적정시간이 경과되면서 응고가 끝나면, 분쇄기로 투입되어 분쇄과정을 거쳐 파우더 형태로 분쇄되어, 분말 자체에 고유한 색상을 가진 착색재료로 완성된다.When the petrified stone powder colored by the dyeing process is solidified as the appropriate time passes, the powder is put into a pulverizer, pulverized into a powder form through a pulverizing process, and finished with a coloring material having a unique color in the powder itself.

분말상 착색재료는 통상의 점착제에 희석하여 스프레이 방식으로 대상물의 외장표면에 시공할 수 있도록 하는데, 이때 분말의 거칠기는 모래 보다 작도록 하는 것이 바람직하다.Powdered coloring material can be diluted on a conventional adhesive to be applied to the exterior surface of the object by a spray method, wherein the roughness of the powder is preferably smaller than sand.

분말상으로 가공된 착색재료는 각기 색상별로 포장되어 건축물의 시공현장에서 사용할 수 있도록 한다.The colored materials processed into powder form are packaged for each color so that they can be used in the construction site of the building.

따라서, 상기와 같은 본 발명은 자연에 무수하게 산재된 석화석을 이용하여 선별과 착색 및 분쇄과정을 거쳐 천연의 분말상 착색재료로 가공함으로써 건축소재 또는 미술품의 외장 마감재로 널리 활용할 수 있도록 하였다.Therefore, the present invention as described above was able to be widely used as an exterior finishing material of building materials or art by processing into natural powdered coloring materials through the process of sorting, coloring and grinding using petrified stone scattered in nature.

특히 본 발명에 의한 착색재료는 천연의 소재를 사용함으로써 자연미와 풍부한 질감을 얻을 수 있으며, 내구성 및 내화학적인 특성을 동시에 함유할 수 있는 것이다.In particular, the coloring material according to the present invention can obtain a natural beauty and a rich texture by using a natural material, and can contain both durability and chemical resistance at the same time.

또한 석화석은 다른 종류의 자연석에 비해 기공층을 많이 함유하고 있으므로 가공이 상대적으로 용이하고 채취가 용이하여 자연의 훼손을 최소화할 수 있게 된다.In addition, the petrified stone contains more pore layer than other kinds of natural stone, so processing is relatively easy and the collection is easy to minimize the damage of nature.

이와 같은 본 발명의 석화석 가공방법은 비교적 간단한 공정으로 소비자가 요구하는 다양한 색상의 착색재료를 얻을 수 있게 됨으로써, 가공에 따른 비용이 저렴한 반면 외장 마감재로 활용할 때 그 풍부한 자연미적 효과를 얻을 수 있으며, 시공후 내구성과 내화학성을 향상시켜 변형을 최소화 할 수 있는 장점이 있다.Such a petrified stone processing method of the present invention can obtain a variety of color materials required by the consumer in a relatively simple process, while the cost of processing is inexpensive, but when used as an exterior finishing material, a rich natural aesthetic effect can be obtained. After construction, it has the advantage of minimizing deformation by improving durability and chemical resistance.
