Description

착화탄 점결제의 제조방법Method for preparing complex coal binder

본 발명은 연소물질의 점결용의 접착물에 관한 것으로서, 더욱 구체적으로는 탄소제의 연소물을 소정의 형상으로 성형함에 있어서 이들 연소물을 결착시키는 일종의 연소성이 강한 접착제를 제조하는 방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to adhesives for caking of combustion materials, and more particularly, to a method of producing a kind of highly combustible adhesives that bind these combustion products in forming a carbon combustion product into a predetermined shape.

일반적으로 무연탄등으로 제조된 연탄등은 점화에 숯을 이용하거나 탄화물로 되는 착화탄을 사용하고 있으나 착화탄이 착화시에 다량의 연기가 발생되므로 실내가 크게 오염되거나 악취가 다량 존재하여 사용에 커다란 문제가 되어 왔다.In general, coal briquettes made of anthracite lamps use charcoal or ignition charcoal for ignition, but when the ignition is ignited, a large amount of smoke is generated. It has been a problem.

이같은 문제점을 개선하기 위하여 소위 무연착화탄등이 제조되고 있으나 점착제로 쓰이는 성분이 연소되면서 이취를 내는 것은 종래의 전분 혹은 밀가루를 이용한 접착제로서는 피할 수 없음을 발견하고, 본 발명자는 탄수화물의 사용량을 최대한 적게 사용하면서도 이취, 유독기체를 흡착하는 성질과 접착성질이 겸비된 성분을 배합하여 이취, 유독기체 발생이 적고 건조후에 우수한 강도와 연소후 쉽게 제거될 수 있는 점결제를 개발하였다.In order to improve such a problem, so-called coal-free coal is produced, but odor as the component used as the adhesive is burned is found to be unavoidable by conventional starch or flour-based adhesives. By combining components that adsorb odor, toxic gas and adhesive property while using less, we developed a binder that generates less odor, toxic gas and has excellent strength after drying and can be easily removed after combustion.

종래에 착화탄 제조에 사용되는 점결제는 전분 혹은 밀가루등의 탄수화물에 물을 가하여 끊여 호화시킨 것으로서 200g 중량의 착화탄 제조에 통상 12g 이상이 사용되고 있다. 이같은 종래의 점결제는 밀가루에 함유된 수분과 글루텐 등의 단백질 성분이 연소되면서 역겨운 냄새를 발생시키고 수분이 다량 첨가되어 연소불량에 의한 불연분이 기체화 되어 다량의 연소기체가 발생되었다.Conventionally, the binder used in the production of complex coal is obtained by adding water to carbohydrates, such as starch or flour, and then laundering it. Such conventional binders produce disgusting odors as the protein components such as water and gluten in the flour are burned, and a large amount of water is added to gasify the non-combustibles due to the combustion failure to generate a large amount of combustion gas.

본 발명은 순수한 전분을 무수상태에서 호화시킨 것을 메트라칼슘알루미노피레이트(4CaO·Al2O3·Fe2O3) , 트리칼슘알루미네이트 (3CaO·Al2O3) , 트리칼슘실리케이트 (3CaO·SiO2) 및 디 칼슘실리케이트 (2CaO -SiO2)의 혼합물과 혼합하여 탄화물질로 되는 연소물질을 점결시키므로서 연소중에 발생되는 악취와 유독기체가 흡수제거되면서 안정된 구조체를 이룬 것을 발견하여 본 발명을 완성하였다.The invention Metra calcium aluminate nopi rate that was expensive pure starch in the dry state (4CaO · Al 2 O 3 · Fe 2 O 3), tricalcium aluminate (3CaO · Al 2 O 3) , tricalcium silicate (3CaO By mixing with the mixture of SiO 2 ) and dicalcium silicate (2CaO -SiO 2 ) to calibrate the combustion material to be carbonized material, it has been found that the odor and toxic gas generated during combustion are absorbed and removed to form a stable structure. Was completed.

본 발명에서는 전분의 호화에 있어서 종래의 물에 용해시켜 팽윤에 의한 호화를 유도하는 끊이는 방법이 아니고 수산화나트륨, 수산화칼륨, 황화칼륨시아네이트, 요오드칼륨, 질산암모니아, 질산은, 고농도염화물 또는 이것의 혼합물을 0.5-30%의 농도로 조합한 염류를 전분체에 대하여 중량비로 2-5%를 교반혼화시켜서 전분의 미셀구조를 파괴시켰다. 그 결과, 무수상태를 이룬 상태에서도 전분립의 미셀구조가 파괴되어 수분을 첨가하면 즉시, 팽윤되면서 겔화가 완성될 수 있어 강력한 접착력이 있는 풀이 될 수 있다.In the present invention, in the gelatinization of starch is not a continuous method of dissolving in conventional water to induce gelatinization by swelling, sodium hydroxide, potassium hydroxide, potassium sulfide cyanate, potassium iodide, ammonia nitrate, silver nitrate, high concentration chloride or this Was mixed with a mixture of 0.5-30% at a concentration of 2-5% by weight with respect to the starch to destroy the starch micelle structure. As a result, even in the anhydrous state, the micelle structure of the starch granules is destroyed, and when water is added, gelation can be completed as it swells, thereby making it a strong adhesive paste.

상기한 호화처리된 전분에 테트라칼슘알루미노피레이트, 트리칼륨알루미네이트, 트리 혹은 디칼슘실리케이트의 혼합물을 미립분말 상태로 혼합하여 준다.Tetracalcium aluminopyrate, tripotassium aluminate, tri or dicalcium silicate is mixed in the above finely treated starch in the form of fine powder.

본 발명의 테트라칼슘알루미노피레이트, 트리칼슘알루미네이트 등의 혼합물은 CaCO3의 순도 95% 이상의 양질석회석 80-90%, SiO2함량 60-70%인 점토광물 10-15%, 연규석, 백토, 규조토등의 규석혼합물 2-5%, 파일라이터신더, 동환, 사철, 적리(赤리)등의 혼합물 1-2%, 보오키사이트, 마그네사이트, 돌로마이트의 혼합물 1-2%로 되는 광물 분쇄혼합물을 600-1200℃의 온도로 소성시켜서 제조한다.The mixture of tetracalcium aluminopyrate, tricalcium aluminate, etc. of the present invention is high quality limestone 80-90% of CaCO 3 or higher, 10-15% clay mineral having a SiO 2 content of 60-70%, soft silica, clay, Mineral crushed mixture consisting of 2-5% of the mixture of silica such as diatomaceous earth, 1-2% of the mixture of writer writer, copper ring, iron and sand, and 1-2% of the mixture of bokisite, magnesite and dolomite. Prepared by firing at a temperature of 600-1200 ℃.

이들은 물과 접촉되면 알루민산 3칼슘이 과포화되어 급격히 6방정계 알루민산칼슘 수화물로 되며 주변의 황산(SO4 -2)과 반응되어 고용체가 생성되고 CaO는 Ca(OH)2로 되면서, 규산칼슘 수화물에 의한 응결작용이 발생된다. 이같은 응결작용에 덧붙여서 호화전분도 주변의 수분을 흡수하여 급속히 미셀구조의 파괴에 따른 접착작용이 진행된다.When contacted with water, they are supersaturated with tricalcium aluminate to rapidly form hexagonal calcium aluminate hydrate, react with the surrounding sulfuric acid (SO 4 -2 ) to form a solid solution, and CaO to Ca (OH) 2 , calcium silicate. Condensation by hydrate occurs. In addition to this coagulation action, gelatinized starch absorbs the surrounding water and rapidly proceeds the adhesion action due to the breakdown of the micelle structure.

이상의 칼슘알루미노실리케이트에 의한 응결작용과 전분호화에 따른 접착작용은 반드시 수분이 첨가되었을 때에만 일어나는 반응이다.The above-mentioned coagulation action by calcium aluminosilicate and adhesion action due to pregelatinization are reactions that occur only when water is added.

따라서, 본 발명의 점결제는 상기한 호화처리된 완전수용성의 전분 약 40%와 칼슘알루미노실리케이트계의 고온소성물 60%를 균일하게 혼합하여 포장되며 최종적인 사용자가 임의로 10-20배의 물을 첨가하여 점결제로 사용할 수 있다.Therefore, the binder of the present invention is packaged by uniformly mixing about 40% of the above-mentioned gelatinized fully water-soluble starch and 60% high-temperature calcined calcium aluminosilicate-based, and the final user arbitrarily 10-20 times water Can be used as a caking additive.

순도 95%의 석회석 8㎏, 점토 10㎏, 규조토 3㎏, 적리 2㎏, 보오키사이트 1㎏, 돌로마이트 1㎏을 고온소성로에 넣고 800℃로 2시간, 1100℃로 3시간 가열처리한 다음 실온냉각 후 분쇄기로 400-600㎛의 입경이 되도록 마쇄한다.8 kg of limestone with 95% purity, 10 kg of clay, 3 kg of diatomaceous earth, 2 kg of red clay, 1 kg of bokisite, 1 kg of dolomite were put in a high temperature baking furnace and heated at 800 ° C. for 2 hours and 1100 ° C. for 3 hours. After cooling, the grinder is ground to a particle size of 400-600 μm.

[실시예 2]Example 2

[착화탄 제조][Ignition Coal Production]

톱밥의 탄화물을 200g 취하여 상기한 실시예 1에 의하여 얻은 분상체를 약 7g 배합하여 물 20g에 용해시킨 다음 탄화물과 잘 뒤섞어서 톱밥탄화물로된 착화탄을 제조하였다. 이 착화탄은 건조작업이 필요없이 즉시 점화시킨 결과 종래의 연소시에 발생되는 악취와 연기가 거의 느낄 수 없었다.200 g of sawdust carbide was mixed with about 7 g of the powder obtained in Example 1, dissolved in 20 g of water, and then mixed with carbide to prepare a sawdust carbide complex carbon. The ignition coal was ignited immediately without the need for drying, and as a result, there was little odor and smoke generated during conventional combustion.

상기한 실시예에 나타나듯이 본 발명에 의한 착화탄은 착화순간에 역겨운 냄새와 유황기체의 발생이 거의 없다. 그 이유는 응결체로 첨가된 고온 소성된 칼슘알루미노피레이트, 규산질체가 내부에 미세기공이 다수 존재하면서 석회질체가 갖는 흡기성에 의하여 연소중의 냄새를 흡착하는 것으로 추측되며, 일단 연소가 진행되어도 이들의 구조에는 전혀 변화가 없이 강한 결합력을 나타내기 때문이다.As shown in the above embodiment, the ignition coal according to the present invention hardly generates disgusting odors and sulfur gas at the time of ignition. The reason for this is that high-temperature calcined calcium aluminopyrate and siliceous bodies added as agglomerates adsorb odor during combustion due to the inspiratory properties of the calcified bodies due to the presence of many micropores therein. This is because it shows strong bonding force without any change.

또한, 접착제로 사용된 것도 순수한 전분만이 사용되므로 연소 후에 CO2, H2O 이외에는 아민산화물, 유황산화물의 방출이 없어서 단백질 연소등에 의한 역겨운 냄새는 거의 사라지게 되는 것이며, 일단 접착 및 응결이 완결된 다음에는 강도가 우수하여 이송 운반중에 파손도 전무하게 되었다.In addition, since only pure starch is used as an adhesive, there is no release of amine oxides and sulfur oxides other than CO 2 and H 2 O after combustion, so disgusting odors caused by protein combustion are almost disappeared. Next, the strength was excellent, so that no damage occurred during transportation.

따라서 가정에서 착화물 위에 집게등으로 파지하여 점화할때, 약간만 힘을 가하여도 부서지는 폐단도 없어지게 되었다.Therefore, when gripped and ignited with tongs on the complex at home, even with a little force, the broken ends are eliminated.
