Description

석회유 슬러지를 이용한 경량 단열재의 제조방법Manufacturing method of lightweight insulation using lime oil sludge

본 발명은 건축물의 경량 단열재 제조방법에 관한 것으로 좀더 상세하게는 석회유 제조공정에서 발생된 슬러지를 주원료로 하고 여기에 부수적 원료를 첨가해 단열성이 우수한 경량 단열재를 제조하는 방법에 관한 것이다.The present invention relates to a method for manufacturing a lightweight insulating material of a building, and more particularly, to a method for manufacturing a lightweight insulating material having excellent thermal insulation by adding a secondary raw material to the sludge generated in the lime oil manufacturing process.

종래의 단열재는 압면이 주성분을 이루고 있어 취급 또는 사용시 탈락이 되는 단점이 있을뿐만 아니라 발암물질로 규제되어 현재 사용을 하지 않고 있으며, 스치로폴의 경우 단열효과는 뛰어나지만 내열성, 내구성이 약하고 화재시 유독가스가 발생하며, 또 시공시에 판상의 연결부분에 의해 단열효과가 낮아지는 단점이 있었다. 또한 석고보드의 경우 비중이 크고 연결부분으로 열손실이 되는 등 다수의 문제점이 있었다.Conventional heat insulators have the main component of the pressing, which is not only eliminated when handled or used, but also regulated as a carcinogen and are not used at present. In addition, there was a disadvantage that the insulation effect is lowered by the plate-like connection portion during construction. In addition, gypsum board has a large number of problems, such as a large specific gravity and heat loss to the connecting portion.

한편 석회유 슬러지는 인체에 무해하지만 비중이 크고 응집력이 약한 문제점이 있어 폐기처분시 자원낭비와 매립지 확보라는 큰 문제점을 가지고 있었다.Lime oil sludge, on the other hand, is harmless to the human body, but has a problem of large specific gravity and weak cohesiveness, resulting in waste of resources and disposal of landfills.

본 발명은 상기한 제반 문제점을 해결하여 석회유 슬러지를 이용해 단열성이 우수하고 인체에 무해하며, 시공성이 우수한 경량 단열재를 제공하는데 소기의 목적하는 바가 있다.The present invention is intended to solve the above problems by using a lime oil sludge to provide an excellent heat insulation and harmless to the human body, and excellent light insulation material with excellent workability.

제1도는 본 발명의 공정도.1 is a process diagram of the present invention.

본 발명의 석회유 슬러지를 이용한 경량 단열재의 제조방법에서 석회유 슬러지가 주원료로 되며 슬러지가 가지지 못한 성질을 부수적 원료로 첨가하는 수단을 강구하였다.In the method for producing a lightweight insulating material using lime oil sludge of the present invention, a means for adding lime oil sludge as a main raw material and having no sludge as a secondary raw material was devised.

본 발명의 석회유 슬러지를 이용한 경량 단열재의 제조방법에 관한 바람직한 실시 예를 상세히 설명하면 다음과 같다.Referring to the preferred embodiment of the manufacturing method of the lightweight insulation using the lime oil sludge of the present invention in detail as follows.

석회유 슬러지를 구성하는 1,2차 잔사는 로타리 슬레거와 석회유 진동체에서 하이드로 잔사는 탈탄산조에서 발생하여 사용비율은 슬러지 전체 중량비에 1차잔사는 11%, 2차잔사는 13%, 하이드로 잔사는 76%를 사용한다.(이하 슬러지라 통칭함)The primary and secondary residues of lime oil sludge are from rotary sludge and lime oil vibrating bodies. Hydro residues are generated from the decarbonation tank. % Is used (hereinafter referred to as sludge).

[제 1 공정][Step 1]

슬러지를 자연 건조시켜 포함하고 있는 30~40%의 수분을 어느정도 제거한다.Naturally dry the sludge to remove some 30 ~ 40% of moisture.

[제 2 공정]Second Process

자연 건조된 슬러지를 건조로에 넣고 약 200~300℃에서 1~2시간 정도 건조한다.The naturally dried sludge is placed in a drying furnace and dried at about 200 to 300 ° C. for about 1 to 2 hours.

[제 3 공정][Third process]

건조된 슬러지를 0.01~0.03m/m 정도로 분쇄한다.Crush the dried sludge to about 0.01 ~ 0.03m / m.

[제 4 공정][4th process]

분쇄된 슬러지 중량비 66%와 1~2m/m 크기의 스치로폴 16%, 마그네시아 16%, 안전제 2%를 혼합한다.66% crushed sludge, 16% Schiropol, 1-2% magnesia, and 2% safety agent are mixed.

[제 5 공정][5th process]

포장하여 출하한다.Packed and shipped.

이상과 같은 공정과정으로 제조된 단열재는 물을 섞어 사용하고, 물의 양은 미장시공과 후로킹 시공에 따라 다르며 본 발명의 작용은 상세히 설명하면 다음과 같다.The heat insulating material prepared by the above process is used to mix water, the amount of water depends on the plastering and flocking construction and the operation of the present invention will be described in detail as follows.

우선 벽체 등에 미장사공 또는 후로킹 시공을 하면 연결부분은 없어지고 또 스치로폼이 촘촘하게 분포되면서 슬러지와 마그네시아 안정재가 구성되어지며, 건조과정에서 스치로폼이 미세하게 팽착하고 이로 인해 면적이 넓어지는 현상이 생기게 되므로 균열이 발생되지 않고 건조되며 마그네시아는 응집력을 주고 안정재는 응집력을 주면서 화학적 반응으로 가스가 생기는 것을 방지하는 작용을 하게 되는 것이다.First of all, if you make a plastering or locking work on the wall, the connection part disappears and the styrofoam is densely distributed, and the sludge and magnesia stabilizer are composed. It does not occur, it is dried and magnesia gives cohesion and stabilizer gives cohesion and prevents gas from chemical reaction.

위와 같은 본 발명은 폐기처분 하는 슬러지와 스치로폼을 주원료로 활용할 수 있어 자원재활용과 매립지 확보에 따르는 문제점을 해결하고 품질이 우수한 경량 단열재를 저렴한 가격에 제공할 수 있는 매우 유익한 발명이다.The present invention as described above is a very beneficial invention that can utilize the sludge and styrofoam to be disposed as the main raw material to solve the problems caused by resource recycling and landfill and provide a high quality lightweight insulation at a low price.
