본 발명은 폐분체파우더 재생방법에 관한 것으로서 더욱 상세하게는 각종의 산업현장에서 분체도료를 이용하여 도장작업이 완료된 후 발생하는 폐분체파우더를 재생하여 분체파우더로서 활용할 수 있도록 하는 방법의 제공에 관한 것이다.The present invention relates to a waste powder recycling method, and more particularly, to a method for reproducing waste powder powder generated after finishing a coating operation using powder coating in various industrial sites and using the same as powder powder. will be.
분체파우더는 각종의 산업현장에서 분체도장작업에 사용되는 것으로서 액체 도료와는 달리 분말로 되어있는 것이 특징이다.Powder powder is used for powder coating work in various industrial sites, and is characterized by being powder, unlike liquid paint.
각종의 산업현장에서 분체도장작업이 완료되고나면 작업량의 20 - 30%의 분체도료가 도장작업과정에서 낙하되는 폐분체파우더가 분말 혹은 일정크기로 결합된 덩어리로 발생하게된다.After the powder coating work is completed in various industrial sites, 20-30% of the powder coating powder is generated as powder or agglomerated powders in a certain size.
종래에는 이러한 폐분체파우더를 재활용하기 위한 구체적인 기술과 방안이 제시되지 않은관계로 전량수거하여 소각에 의한 폐기처분을 행하고 있다.Conventionally, since the specific techniques and methods for recycling such waste powder powder have not been presented, the entire volume is collected and disposed of by incineration.
도장작업이 완료된 후 발생하는 폐분체파우더를 소각처분할 경우에는 소각에 따르는 비용부담이 가중됨은 물론, 폐분체파우더의 화학적 특성에 의하여 소각과정에서 발생하는 여러 요인에 의하여 주변환경을 오염시키는 문제점을 가지게 된다.When incineration of waste powder powder generated after the painting work is completed, the burden of incineration increases, and the chemical characteristics of the waste powder powder contaminate the surrounding environment due to various factors generated during incineration. Have.
즉, 폐분체파우더를 소각함으로서 발생하는 악취는 물론 유독성가스에 의하여 주변환경이 오염됨은 물론, 심각한 대기오염의 원인을 제공하고, 소각에 따르는 불필요한 에너지의 낭비를 초래하게하고 더욱이 재활용가치가 충분한 폐분체파우더를 소각처리함으로서 원자재의 낭비를 가져오게 한다.In other words, not only the odor generated by incineration of waste powder powder, but also environmental pollution by toxic gas, as well as the cause of serious air pollution, cause waste of unnecessary energy by incineration, and moreover, waste with sufficient recycling value Incineration of powder powder leads to waste of raw materials.
특히 폐분체파우더가 수거되어 소각처리되지 못하고 일부 누출될 경우에는 토양의 오염은 물론 수질오염에 까지 이어지는 등 그 폐해가 심각하게 된다.Particularly, when the waste powder powder is collected and cannot be incinerated and some leakage occurs, the damage is serious, such as soil contamination and water pollution.
이에 본 발명에서는 상기와 같은 문제점들을 해결하기 위하여 도장작업후 발생하는 폐분체파우더를 재활용하여 신제(재활용에 의하여 생산되지 않은 분체파우더 ; 이하 신제라 한다)와 거의 동일한 분체파우더를 제공함으로서, 폐분체파우더를 처리함으로서 발생하는 원재료와 에너지의 낭비를 방지하고 환경오염의 원인을 근원적으로 차단할 수 있도록 함을 목적으로 한다.In the present invention, in order to solve the above problems, by recycling the waste powder powder generated after the coating operation to provide a powder powder almost the same as the new agent (powder powder not produced by recycling; hereinafter referred to as a new agent), waste powder It aims to prevent waste of raw materials and energy generated by processing powder and to fundamentally block the cause of environmental pollution.
제 1도는 본 발명의 폐분체파우더를 재생하는 과정을 공정별로 설명한 블록다이어그램1 is a block diagram illustrating the process of regenerating the waste powder powder of the present invention by process
이하 첨부되는 도면과 관련하여 본 발명인 폐분체파우더 재생방법에 대한 바람직한 실시예를 설명한다.Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention powder recycling powder method.
본 발명의 폐분체파우더 재생방법은 수거한 폐분체파우더를 색상별로 분리하고, 폐분체파우더 이외의 큰 이물질과 분리하는 선별공정과;The waste powder powder regeneration method of the present invention comprises: a sorting process of separating the collected waste powder powder by color and separating it from a large foreign matter other than the waste powder powder;
선별완료된 폐분체파우더내에 폐분체파우더와 비슷한 크기로 존재하는 이물질을 제거하는 정제공정과;A purification step of removing foreign substances present in the sorted waste powder powder in the same size as the waste powder powder;
폐분체파우더를 목적으로 하는 색상으로 재생하기 위하여 안료와 각종의 첨가물을 혼합하는 혼합공정, 혼합완료된 파우더를 압출하는 압출공정과 압출된 압출박편분을 분쇄하여 미립자로 만드는 1,2차 분쇄공정과 분쇄된 미립자와 이물질을 분리하여 신제와 같은 분체파우더를 완성하는 1,2차미립자추출공정으로 크게 구분되며, 이하 각 공정에 대하여 상세하게 설명하면 다음과 같다.Mixing process of mixing pigment and various additives, extrusion process of extruding mixed powder, and first and second crushing process of crushing extruded extruded flake powder to fine particles The first and second fine particle extraction process of separating the pulverized fine particles and foreign matter to complete the powder powder, such as a new agent, are described in detail below for each process.
(선별공정)(Selection process)
선별공정은 분체도장과정에 발생한 폐분체파우더를 수거하여 폐분체도료에 함유된 파지, 목재, 직물조각등과 같은 큰 불순물을 제거하고 색상별로 구분하여 분리한다.The sorting process collects the waste powder powder generated during the powder coating process and removes large impurities such as waste paper, wood, and fabric scraps from the powder coating and separates them by color.
(정제공정)(Refining process)
정제공정은 선별이 완료된 폐분체파우더를 망체를 가지는 회전체에 투입하여 폐분체파우더외의 불순물과 구분하여 분리한다.In the refining process, the sorted waste powder powder is put into a rotating body having a net and separated from impurities other than the waste powder powder.
상기 회전체에는 불순물과 폐분체파우더를 분리시킬 수 있도록 폐분체파우더는 통과하고 이보다 큰 이물질은 통과할 수 없는 형태의 여과망이 설치되어 있음은 당연할 것이다.It will be apparent that the rotating body is provided with a filtering network of a type through which the waste powder powder passes and larger foreign substances cannot pass through to separate the impurities from the waste powder powder.
(혼합공정)(Mixing process)
정제공정에 의하여 불순물이 분리된 폐분체파우더를 믹서기에 투입한 후 안료, 정화제, 소광제 및 수지등을 투입하여 골고루 혼합하여 목적하는 색상을 표현할 수 있도록 한다.The waste powder powder from which impurities are separated by the purification process is added to a blender, and then pigments, purifiers, quenchers and resins are mixed and mixed evenly to express a desired color.
여기에 투입되는 안료등의 첨가물은 폐분체파우더의 색상과 동일한 안료를 투입하여, 투입량은 신제제조시 사용되는 색상성분표에 기인한다.Additives such as pigments are added to the same pigment as the powder of the waste powder, the dosage is due to the color component table used in the new production.
(압출공정)(Extrusion Process)
압출공정은 첨가물의 혼합이 완료된 폐분체파우더를 압출기에 투입하여 박판형태로 압출한다.In the extrusion process, the waste powder powder, in which the additives are mixed, is put into an extruder and extruded in a thin plate form.
이때, 압출을 위하여 가하는 열에 의하여 박판형태로 압출되는 폐분체파우더에는 자체수분이 소멸된다.At this time, the self-water is extinguished in the waste powder powder extruded in a thin plate form by the heat applied for extrusion.
(1차분쇄공정)(First grinding process)
박판형태로 압출된 폐분체판은 다수개의 회전칼날을 가지는 분쇄기에 투입하여 약 0.5-2.0㎟의 박편으로 분쇄한다.The waste powder plate extruded in the form of a thin plate is put into a grinder having a plurality of rotary blades and pulverized into flakes of about 0.5-2.0 mm 2.
(2차분쇄공정)(Secondary grinding process)
1차분쇄공정에서 작은크기로 분쇄된 박편을 고분자분쇄기에 투입하여 신제가 가지는 분체파우더와 같은 입자크기의 미립자로 분쇄된다.In the first grinding process, the crushed flakes are put into a polymer crusher and pulverized into fine particles having a particle size such as powder powder of a new agent.
(1차 미립자 추출공정)(Primary Particulate Extraction Process)
고분자분쇄기에 의하여 분쇄된 미립자는 사이클론사이클론과 연결된 집진기의 흡입력에 의하여 유입되면서 와류하게 되고, 이 과정에서 무거운 미립자는 사이클론의 하방으로 낙하되어 모여지게 된다.The fine particles pulverized by the polymer crusher are vortexed by the suction force of the dust collector connected to the cyclone cyclone, and in this process, the heavy fine particles are dropped and collected under the cyclone.
그리고, 미립자와 함께 혼합되어있던 가벼운 먼지, 이물질등은 집진기로 집진되어 진다.Then, light dust and foreign matter mixed with the fine particles are collected by the dust collector.
상기 집진기의 흡입력은 미립자가 흡입되지 않을 정도로 되어야 함은 당연할 것이며, 집진기로 유입되는 먼지, 이물질에는 수분을 분사하여 배출공기에 포함된 잔진을 흡착하여 낙하하도록 하고, 배출통로에는 여과필터를 설치하여 대기오염이 방지되도록 한다.Naturally, the suction force of the dust collector should be enough to prevent the inhalation of particulates, and injects moisture into the dust and foreign matter that enters the dust collector, thereby adsorbing the residue contained in the exhaust air, and installing a filtration filter in the discharge passage. To prevent air pollution.
(2차미립자추출공정)(Secondary particle extraction process)
사이클론의 하방에 모여진 미립자를 미세한 조직의 여과망을 가지는 정제기에 투입하여 여과망으로 미립자를 통과시켜 여과망을 통과하는 분말을 포장하여 분체파우더를 완성한다.Particles collected under the cyclone are introduced into a purifier having a microstructured filtering network, and the fine particles are passed through the filtering network to package the powder passing through the filtering network to complete the powder powder.
상기의 공정을 거쳐 최종여과망을 통과하지 못한 미립자와 집진기에 먼지 및 이물질과 함께 집진된 미립자는 2차분쇄공정에 투입하여 1,2차미립자추출공정을 거치도록 하는 반복과정을 통하여 분체파우더를 얻을 수 있도록 한다.Particles that have not passed the final filtration network through the above process and particulates collected together with dust and foreign matter in the dust collector are introduced into the secondary grinding process to obtain powder powder through an iterative process to undergo the first and second fine particle extraction process. To help.
상기와 같은 방법으로 폐분체파우더를 반복적으로 재생할 경우에는 발생되는 폐분체파우더의 약 99.8%정도를 활용할 수 있으며, 나머지 약 0.2%정도만을 소각 처리하면된다.When the waste powder powder is repeatedly recycled in the above manner, about 99.8% of the waste powder powder generated may be used, and only about 0.2% of the waste powder may be incinerated.
그러므로 폐분체파우더를 소각처리하는데 필요한 비용을 절감할 수 있게 됨은 물론, 폐분체파우더를 재생함으로서 원자재의 낭비와 소각에 필요한 에너지원을 절감할 수 있게되고, 소각시 발생하는 악취나 유독가스를 방지하여 유해환경으로 변화되는 것을 방지할 수 있는 것이다.Therefore, not only the cost required for incineration of the waste powder powder can be reduced, but also the waste powder can be reduced by reducing the energy source required for incineration and incineration, and the odor or toxic gas generated during incineration can be reduced. It can prevent the change to harmful environment.
이상과 같은 본 발명은 폐분체파우더를 재생활용함으로서 자원과 에너지원의 낭비를 막고, 악취와 유독가스등에 의한 대기, 토질 및 수질오염을 방지할 수 있는 효과를 가진다.The present invention as described above has the effect of preventing the waste of resources and energy sources by recycling waste powder powder, and prevents air, soil and water pollution by odor and toxic gas.
