It is widely used in many fields such as building materials, packing cushions, etc.
상기 스티로폼은 각종 분야에서 유용하게 널리 사용되고 있지만, 쓰레기처리장, 어시장, 전자상가등의 사용처에서 폐기물이 되면, 자체적인 공극률이 크기 때문에 환경오염 측면에서 상당히 불리하고, 그에 따른 용이한 폐처리가 요구되어 왔다.The styrofoam is widely used in various fields, but when it becomes a waste at a waste disposal site, a fish market, an electronics market, etc., since its own porosity is large, it is considerably disadvantageous in terms of environmental pollution, and thus easy waste treatment is required. come.

여기서 본 발명에 따른 폐스티로폼 재생 방법의 각 실시예를 첨부한 도면을 참조하여 더욱 상세하게 설명하면 다음과 같다.Hereinafter, each embodiment of the waste styrofoam regeneration method according to the present invention will be described in more detail with reference to the accompanying drawings.
첨부한 도 1은 본 발명에 따른 폐스티로폼 재생 방법의 일실시예를 설명하기 위한 도면으로서, 상기 폐스티로폼은 본원 출원인에 의하여 출원/등록된 다단 압축 방식의 스티로폼 감용기에 의하여 압축 처리된 것을 사용한다.1 is a view for explaining an embodiment of a waste styrofoam regeneration method according to the present invention, the waste styrofoam is used that is compressed by a multi-stage compression type styrofoam reducer filed / registered by the applicant of the present application do.
상기 압축 처리된 폐스티로폼의 단면을 보면 본래 구형태의 스티로폼 입자(발포된 PS비드)가 납작하게 압축된 상태로서, 각 입자가 납작한 상태로 서로 적층된 구조를 이루고 있다.In the cross-section of the compressed waste styrofoam, the spherical styrofoam particles (foamed PS beads) are compressed in a flat state, and the particles are stacked on each other in a flat state.
상기와 같은 구조를 이루고 있는 폐스티로폼을 분쇄수단을 사용하여 1차로 분쇄시키는 공정을 진행시키면, 페스티로폼은 감자 정도의 크기로 분쇄되는 바, 발포되었던 다수의 구상 PS비드가 납작하게 압축되어 서로 붙어있는 상태가 된다.When the waste styrofoam forming the above structure is first crushed using a grinding means, the styrofoam is crushed to the size of a potato bar, and the spherical spherical PS beads that have been foamed are compressed flat and stuck together. It is in a state.
다음으로, 상기 다수의 PS비드가 납작하게 압축되어 붙어 있는 상태로 분쇄된 폐스티로폼을 가열수단을 사용하여 140∼160℃에서, 바람직하기로는 150℃에서 적당한 시간동안 가열하는 공정을 진행시킨다.Next, the process of heating the waste styrofoam pulverized in a state where the plurality of PS beads are flat compressed and adhered at 140 to 160 ° C., preferably at 150 ° C. for a suitable time, is performed using a heating means.
그 결과, 상기 납작한 다수의 PS비드가 그 부피가 수축되며 마치 좁쌀과 같은 0.5∼1.0mm의 구상 PS비드로 형성되어 서로 엉겨 붙어 있는 상태가 된다.As a result, the plurality of flat PS beads are shrunk in volume and formed into spherical PS beads having a thickness of 0.5 to 1.0 mm, such as millet, to be entangled with each other.
상기 적당한 시간 동안이란, 납작한 다수의 PS비드가 마치 좁쌀과 같은 0.5∼1.0mm의 구상 PS비드로 수축되며 형성되는 시점까지의 시간을 말한다.During this suitable time, it refers to the time until the formation of a plurality of flat PS beads contracted into spherical PS beads of 0.5 to 1.0 mm, like millet.
다음으로, 상기 서로 엉겨 붙어 있는 구상의 PS 비드를 2차로 분쇄시키는 공정을 진행함에 따라, 낱개의 구상 PS비드가 되도록 한다.Next, as the secondary grinding of the spherical PS beads are entangled with each other, the individual spherical PS beads are formed.
이어서, 상기 낱개의 구상 PS비드에 펜탄(pentane)가스를 주입하여 적시게 되면, 재생 EPS(Expandable PolyStylene)비드(bead)가 된다.Subsequently, when a pentane gas is injected and wetted into the respective spherical PS beads, a regenerated EPS (Expandable PolyStylene) bead becomes.
이때, 상기 낱개의 구상 PS비드의 내부까지 펜탄가스가 완전히 침투된 상태이다.At this time, the pentane gas is completely penetrated to the inside of the individual spherical PS beads.
마지막으로, 상기 재생 EPS비드를 스팀가열수단으로 가열하는 공정을 진행하는 바, 그 결과로 상기 재생 EPS비드는 본래의 스티로폼 입자의 크기와 부피로 발포되어, 재사용 가능한 상태가 된다.Finally, the process of heating the regenerated EPS beads with steam heating means proceeds, and as a result, the regenerated EPS beads are foamed to the size and volume of the original styrofoam particles, and are in a reusable state.
여기서 본 발명의 다른 실시예를 첨부한 도 2를 참조로 설명하면 다음과 같다.Herein with reference to Figure 2 attached to another embodiment of the present invention.
먼저, 상술한 일실시예와 같이, 다단 압축방식의 스티로폼 감용기에 의하여 감용된 폐스티로폼을 1차로 분쇄시키는 공정을 진행시켜서, 감자 정도의 크기로 분쇄되도록 하는 바, 마찬가지로 발포되었던 다수의 구상 PS비드가 납작하게 압축되어 서로 붙어있는 상태가 된다.First, as in the above-described embodiment, a process of primarily crushing waste styrofoam applied by a styrofoam reducer of a multi-stage compression method is performed so as to be pulverized to a size of a potato. The beads are compressed flat and stuck together.
다음으로, 상기 다수의 PS비드가 납작하게 압축되어 붙어 있는 상태로 분쇄된 감자 크기의 폐스티로폼을 2차로 분쇄시키는 동시에 메쉬로 걸러주는 공정을 진행시켜, 낱개의 납작한 PS비드로 분리되도록 한다.Next, a plurality of PS beads are flattened and pressed into a state in which the crushed potato-sized waste styrofoam is secondly pulverized and subjected to a mesh filtering process to separate the individual flat PS beads.
이때, 상기 낱개의 납작한 PS비드의 크기는 3∼5mm 정도이고 매우 얇은 상태이다.At this time, the size of the single flat PS bead is about 3 to 5mm and very thin state.
다음으로, 상기 낱개의 납작한 PS비드를 가열수단을 사용하여 140∼160℃에서, 바람직하기로는 150℃에서 적당한 시간동안 가열하는 공정을 진행시키는 바, 그 결과, 상기 납작한 각각의 PS비드가 그 부피가 수축되며 마치 좁쌀과 같은 0.5∼1.0mm의 구상 PS비드로 형성된다.Next, the single flat PS beads are heated at a temperature of 140 to 160 ° C., preferably at 150 ° C., for a suitable time using heating means. As a result, each of the flat PS beads has a volume. It contracts and is formed of spherical PS beads of 0.5 ~ 1.0mm like millet.

여기서 본 발명의 또 다른 실시예를 첨부한 도 3을 참조로 설명하면 다음과 같다.Herein with reference to Figure 3 attached to another embodiment of the present invention will be described.
상술한 실시예와 같이, 먼저 다단 압축방식의 스티로폼 감용기에 의하여 감용된 폐스티로폼을 1차로 분쇄시키는 공정을 진행시켜서, 감자정도의 크기로 분쇄되는 바, 마찬가지로 발포되었던 다수의 구상 PS비드가 납작하게 압축되어 서로 붙어 있는 상태가 된다.As in the above-described embodiment, first, a process of first crushing the waste styrofoam adsorbed by the multi-stage compression type styrofoam reducer is pulverized to the size of a potato, and thus a plurality of spherical PS beads that have been foamed are flat. Compressed and stuck together.
다음으로, 상기 다수의 PS비드가 납작하게 압축되어 붙어 있는 상태로 분쇄된 감자 크기의 폐스티로폼을 2차로 분쇄시키는 동시에 메쉬로 걸러주는 공정을 진행시켜, 낱개의 납작한 PS비드로 분리되도록 한다.Next, a plurality of PS beads are flattened and pressed into a state in which the crushed potato-sized waste styrofoam is secondly pulverized and subjected to a mesh filtering process to separate the individual flat PS beads.
다음으로, 상기 각각의 납작한 PS비드에 펜탄(pentane)가스내에 투입하여 상기 재생 EPS 비드가 되도록 한다.Next, each of the flat PS beads is introduced into a pentane gas to be the recycled EPS beads.
이때, 상기 납작한 PS비드는 열풍가열에 의하여 0.5∼1mm의 구상 PS가 되었지만, 펜탄가스를 직접 주입하더라도 0.5∼1mm의 구상으로 수축 형성되고 동시에 펜탄가스로 적시어진 상태이기 때문에, 결국 재생 EPS 비드로 제조된다.At this time, the flat PS beads were spherical PS of 0.5 to 1 mm by hot air heating. However, even though pentane gas was directly injected, the PS beads were contracted and formed into 0.5 to 1 mm spheres and wetted with pentane gas. Are manufactured.
이는, 상술한 일실시예와 다른 실시예의 방법과 비교했을때 열풍으로 가열하는 공정이 배제되어, 최종적으로 재생 EPS비드를 제조하는 그 공정상 간단한 장점이 있는 것이다.This eliminates the process of heating with hot air as compared with the method of one embodiment and the other embodiments described above, and thus has a simple advantage in the process of finally producing recycled EPS beads.
마지막으로, 상기 재생 EPS비드를 스팀가열함으로써, 본래의 크기와 부피를 갖는 스티로폼 입자로 발포되어, 재사용 가능하게 된다.Finally, by steam-heating the regenerated EPS beads, they are foamed into styrofoam particles having original size and volume, and are reusable.
여기서, 본 발명에 따른 폐스티로폼 재생 방법의 또 다른 실시예를 첨부한 도 4를 참조로 설명하면 다음과 같다.Here, with reference to Figure 4 attached to another embodiment of the waste styrofoam regeneration method according to the present invention.
마찬가지로, 먼저 다단 압축방식의 스티로폼 감용기에 의하여 감용된 폐스티로폼을 1차로 분쇄시키는 공정을 진행시켜서, 감자정도의 크기로 분쇄되도록 하고, 발포되었던 다수의 구상 PS비드가 납작하게 압축되어 서로 붙어있는 상태가 되도록 한다.In the same way, the first step is to pulverize the waste styrofoam, which is applied by the multi-stage compression styrofoam reducer, to the size of a potato, and the spherical spherical PS beads that have been foamed are compressed and adhered to each other. To be in a state.
다음으로, 상기 감자 크기로 분쇄된 상태의 폐스티로폼에 펜탄가스를 주입하는 공정을 진행시키는 바, 그 결과, 상기 납작한 다수의 PS비드가 그 부피가 감소되며 마치 좁쌀과 같이 0.5∼1.0mm의 구상 PS비드로 형성되어 서로 엉겨 붙어 있는상태가 되고, 동시에 펜탄가스에 적시어진 상태이기 때문에 곧바로 재생 EPS 비드로 제조된다.Next, a process of injecting pentane gas into the waste styrofoam in the state of potato size is carried out. As a result, the plurality of flat PS beads are reduced in volume and spherical in the shape of 0.5 to 1.0 mm like millet. It is made of PS beads and entangled with each other, and at the same time it is soaked in pentane gas so that it is directly produced as recycled EPS beads.
이어서, 서로 엉겨 붙은 상태의 재생 EPS비드를 2차로 분쇄시키는 공정을 진행시킴으로써, 최종적으로 낱개의 재생 EPS비드로 제조 완료되고, 마지막으로 상기 재생 EPS비드를 스팀가열함으로써, 본래의 크기와 부피를 갖는 스티로폼 입자로 발포되어, 재사용 가능하게 된다.Subsequently, a process of secondly crushing the regenerated EPS beads in a state of being entangled with each other is performed to finally manufacture the individual regenerated EPS beads, and finally, by steam heating the regenerated EPS beads to have original size and volume. Foamed with styrofoam particles, making them reusable.
