Description
본 발명은 친환경 덕트에 관한 것으로, 보다 상세하게는 합성수지를 이용하여 덕트를 만들되, 정전기 발생 억제 능력을 보유시켜 먼지가 부착 내지 쌓이지 않도록 함으로써 유체의 흐름성을 원활하게 하여 모터의 성능 열화를 막고, 소비전력을 절감할 수 있도록 개선된 친환경 덕트에 관한 것이다.The present invention relates to an eco-friendly duct. More specifically, the duct is made using synthetic resin, but has the ability to suppress static electricity generation to prevent dust from adhering or accumulating, thereby smoothing the flow of fluid to prevent performance deterioration of the motor. This is about an eco-friendly duct that has been improved to reduce power consumption.
일반적으로 덕트(Duct)란 유체, 특히 공기가 흘러가는 통로를 제공하는 부재이다.In general, a duct is a member that provides a passage for fluid, especially air, to flow.
이러한 덕트는 공조기나 전열교환기와 연계하여 설치되기도 하고, 환기를 위해 설치되기도 한다.These ducts may be installed in connection with an air conditioner or electric heat exchanger, or may be installed for ventilation.
때문에, 용도에 따라 환기덕트, 급기덕트, 배기덕트 등으로 명명되고 있으며, 다양한 형태를 가지지만 주로 사각형상의 덕트 구조가 일반적이다.Therefore, depending on the purpose, they are called ventilation ducts, air supply ducts, exhaust ducts, etc., and although they have various shapes, the most common is a square-shaped duct structure.
이때, 덕트를 흐르는 공기는 자연환기를 제외하고, 대부분 송풍기에 의해 송풍되는 풍압 혹은 차압에 의해 이루어지며, 송풍기는 상용전원에 의해 구동된다.At this time, except for natural ventilation, the air flowing through the duct is mostly generated by wind pressure or differential pressure blown by a blower, and the blower is driven by commercial power.
또한, 이러한 덕트는 아래 예시와 같이 다양한 형태로 개시되고 있다.Additionally, these ducts are disclosed in various forms, as shown in the examples below.
도시된 바에 따르면, 사각형, 엘보형, 커플링형, 사각레듀사형, 이형레듀사형, 플랫형 등 다양하다.As shown, there are various types such as square, elbow type, coupling type, square reducer type, heterogeneous reducer type, and flat type.
이들 덕트는 종래 대부분 금속판을 가공하여 제조되었으나, 근래에는 합성수지를 이용하여 제조되고 있다.Conventionally, most of these ducts were manufactured by processing metal plates, but recently, they have been manufactured using synthetic resin.
그런데, 합성수지, 특히 PVC로 제조된 덕트의 경우, 대전성이 크기 때문에 정전기력에 의한 먼지 부착에 의해 관 내부에 먼지가 쌓이고 이는 유로 저항이 커지면서 송풍팬을 구동하는 모터의 성능을 열화시키고, 나아가 소비전력을 증대시키는 문제로 커지고 있다.However, in the case of ducts made of synthetic resin, especially PVC, because they are highly charged, dust accumulates inside the pipe due to dust adhesion due to electrostatic force, which increases flow resistance, deteriorates the performance of the motor that drives the blower fan, and further reduces consumption. The problem of increasing power is growing.
하지만, 아직까지 이러한 문제의 해소 방안에 대한 구체적인 접근이나 가시적인 성과(제품화)가 나타나지 않고 있어 이에 대한 개선이 필요한 시점이다.However, there is still no concrete approach or visible results (productization) for resolving these problems, so improvement is needed.
본 발명은 상술한 바와 같은 종래 기술상의 제반 문제점들을 감안하여 이를 해결하고자 창출된 것으로, 합성수지를 이용하여 덕트를 만들되, 정전기 발생 억제 능력을 보유시켜 먼지가 부착 내지 쌓이지 않도록 함으로써 유체의 흐름성을 원활하게 하여 모터의 성능 열화를 막고, 소비전력을 절감할 수 있도록 개선된 친환경 덕트를 제공함에 그 주된 목적이 있다.The present invention was created to solve various problems in the prior art as described above. A duct is made using synthetic resin, but it has the ability to suppress the generation of static electricity to prevent dust from adhering or accumulating, thereby smoothing the flow of fluid. The main purpose is to provide an improved eco-friendly duct to prevent motor performance deterioration and reduce power consumption.
본 발명은 상기한 목적을 달성하기 위한 수단으로, 합성수지에 몬모릴로나이트를 분말 형태로 혼합하여 덕트 형태로 성형한 것을 특징으로 하는 친환경 덕트를 제공한다.As a means to achieve the above object, the present invention provides an eco-friendly duct characterized by mixing montmorillonite in powder form with synthetic resin and molding it into a duct shape.
본 발명에 따르면, 합성수지를 이용하여 덕트를 만들되, 정전기 발생 억제 능력을 보유시켜 먼지가 부착 내지 쌓이지 않도록 함으로써 유체의 흐름성을 원활하게 하여 모터의 성능 열화를 막고, 소비전력을 절감할 수 있도록 개선된 효과를 얻을 수 있다.According to the present invention, a duct is made using synthetic resin, but it has the ability to suppress static electricity generation to prevent dust from adhering or accumulating, thereby improving fluid flow to prevent deterioration of motor performance and reduce power consumption. effects can be achieved.
이하에서는, 본 발명에 따른 바람직한 실시예를 보다 상세하게 설명하기로 한다.Hereinafter, preferred embodiments according to the present invention will be described in more detail.
본 발명 설명에 앞서, 이하의 특정한 구조 내지 기능적 설명들은 단지 본 발명의 개념에 따른 실시예를 설명하기 위한 목적으로 예시된 것으로, 본 발명의 개념에 따른 실시예들은 다양한 형태로 실시될 수 있으며, 본 명세서에 설명된 실시예들에 한정되는 것으로 해석되어서는 아니된다.Prior to describing the present invention, the following specific structural and functional descriptions are merely illustrative for the purpose of explaining embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms. It should not be construed as limited to the embodiments described herein.
본 발명에 따른 친환경 덕트는 합성수지에 몬모릴로나이트를 분말 형태로 혼합하여 성형한 것이 특징이다.The eco-friendly duct according to the present invention is characterized by being molded by mixing montmorillonite in powder form with synthetic resin.
이때, 합성수지는 PVC는 물론, ABS(Acrylonitrile Butadiene Styrene), PE(Polyethylene), PP(Polypropylene), PS(Polystyrene) 등 다양한 형태의 수지가 사용될 수 있다.At this time, various types of synthetic resins can be used, such as PVC (Acrylonitrile Butadiene Styrene), PE (Polyethylene), PP (Polypropylene), and PS (Polystyrene), as well as PVC.
그리고, 몬모릴로나이트는 층상 규산광물의 하나로 smectite로 분류되는 점토광물이다.Montmorillonite is a clay mineral classified as smectite, one of the layered siliceous minerals.
이러한 몬모릴로나이트의 결정구조는 규산 사면체-알루미나 팔면체-규산 사면체의 3층으로 되며, 2:1형 구조라 부르며, 알루미나 팔면체 중심원자인 Al의 일부가 Mg로 치환되어 있기 때문에 결정자체의 정전하가 부족하나 Na+나 Ca2+ 등의 양이온이 결정과 결정 층간에 들어가 안정한 상태를 이룬다.The crystal structure of this montmorillonite consists of three layers of silicic acid tetrahedron, alumina octahedron, and silicic acid tetrahedron, and is called a 2:1 structure. Since some of Al, the central atom of the alumina octahedron, is replaced with Mg, the crystal itself lacks electrostatic charge. Cations such as Na + or Ca 2+ enter between crystals and crystal layers to form a stable state.
이와 같은 구조적 특성 때문에 정전기방지 특징을 가지며, 합성수지에 배합시 먼지나 이물질의 부착을 억제하는데 기여한다.Because of these structural characteristics, it has anti-static properties and contributes to suppressing the adhesion of dust or foreign substances when mixed with synthetic resin.
특히, 몬모릴로나이트 결정표면의 음전하와 층간 양이온의 결합력은 층간 양이온과 물 분자 에너지가 약하기 때문에 층간 양이온이 물 분자를 끌어서 층간이 확대되며, 이는 합성수지와의 교합성을 좋게 한다.In particular, the bonding force between the negative charge on the surface of the montmorillonite crystal and the interlayer cations is weak because the energy of the interlayer cations and water molecules is weak, so the interlayer cations attract water molecules and the interlayer space expands, which improves the compatibility with synthetic resin.
이와 같은 몬모릴로나이트는 항균과 탈취성능에도 효과가 있다.Montmorillonite like this is also effective in antibacterial and deodorizing properties.
아울러, 합성수지에 몬모릴로나이트의 결정을 배향시키면 가스 배리어 성능도 향상된다.In addition, orienting montmorillonite crystals in synthetic resin improves gas barrier performance.
보다 구체적으로, 본 발명에 따른 친환경 덕트는 합성수지 80-90중량%와, 몬모릴로나이트 분말 10-20중량%로 혼합된 수지조성물을 덕트 형상으로 성형하여 만들어진다.More specifically, the eco-friendly duct according to the present invention is made by molding a resin composition mixed with 80-90% by weight of synthetic resin and 10-20% by weight of montmorillonite powder into a duct shape.
이때, 몬모릴로나이트 분말을 10중량% 미만으로 첨가하게 되면 정전기 방지 특성이 떨어지고, 20중량%를 초과하게 되면 정전방지 특성을 증가되지만 수지와의 교합성을 저해하여 성형성을 떨어뜨릴 수 있기 때문에 상기 범위로 한정하는 것이 바람직하다.At this time, if the montmorillonite powder is added in an amount of less than 10% by weight, the anti-static properties decrease, and if it exceeds 20% by weight, the anti-static properties increase, but it may impair the occlusion with the resin and reduce the moldability, so it is within the above range. It is desirable to limit it to .
이에 더하여, 본 발명에서는 먼지 등이 습기와 더해지면서 뭉쳐 고착화되는 것을 억제하기 위해 내습성물질을 더 혼합하여 덕트를 만들 수 있다.In addition, in the present invention, a duct can be made by further mixing a moisture-resistant material to prevent dust, etc. from clumping and sticking together with moisture.
이를 위해, 본 발명에서는 합성수지와 몬모릴로나이트 분말이 혼합된 수지조성물 100중량부에 대해, 시트르산칼륨(Potassium citrate monohydrate) 15중량부, 글리세롤모노스테아레이트(Glycerol Mono stearate) 10중량부를 더 첨가할 수 있다.For this purpose, in the present invention, 15 parts by weight of potassium citrate monohydrate and 10 parts by weight of glycerol monostearate can be further added to 100 parts by weight of a resin composition containing a mixture of synthetic resin and montmorillonite powder.
이때, 시트르산칼륨(Potassium citrate monohydrate)은 CAS No. 6100-05-6에 해당하는 물질로서, 조직 치밀도를 강화시키고, 내습성을 증대시킨다.At this time, potassium citrate (Potassium citrate monohydrate) is CAS No. This substance corresponds to 6100-05-6, which strengthens tissue density and increases moisture resistance.
