Description

식물성 폴리우레탄 도료의 강관 도장장치 {Two-pack polyurethane coating device of steel pipe}Two-pack polyurethane coating device of steel pipe

본 발명은 식물성 폴리우레탄 도료와 속건제를 혼합한 이액형 도료를 강관의 내,외면에 동시에 분사하여 도장이 이루어도록 하는 수단으로 간편하고 신속하게 속건형 식물성 폴리우레탄 도료의 도장을 할 수 있게 되어 도장설비의 최소화 및 공간활용성을 크게 향상시키고 인체에 무해하면서 내염성 및 내후성이 우수한 친환경 강관을 제공할 수 있도록 한 식물성 폴리우레탄 도료의 강관 도장장치에 관한 것이다.
The present invention is a means for spraying the two-component paint mixed with a vegetable polyurethane paint and a quick-drying agent on the inner and outer surfaces of the steel pipe at the same time to be able to easily and quickly to paint the quick-drying vegetable polyurethane paint The present invention relates to a steel pipe coating device of vegetable polyurethane paint, which greatly improves the minimization and space utilization of a painting facility and provides an eco-friendly steel pipe that is harmless to human body and has excellent flame resistance and weather resistance.

일반적으로 상하수도와 같은 유체 이송용 관으로 사용되는 강관은 그 성질상 내부에 흘러가는 물에 의하여 철 성분이 용해되고, 이로 인하여 수질을 악화시킬 뿐만 아니라, 금속관의 내벽이 부식되는 문제가 발생하므로, 이러한 부식을 방지하기 위하여 강관의 내면 및 외면에는 도료를 도장하여 사용하는 것이 일반적이다.
In general, steel pipes used as fluid transport pipes, such as water and sewage, are dissolved in iron by water flowing therein, thereby deteriorating water quality and causing corrosion of inner walls of metal pipes. In order to prevent such corrosion, it is common to use paint on the inner and outer surfaces of the steel pipe.

그러나 강관에 도장된 도료는 석유화학에서 추출된 원료를 사용하여 제조하므로 원료 생산시 발생된 산업폐기물의 생성 및 분해되지 않는 폐기물의 처리가 곤라하여 환경오염을 유발할 뿐만 아니라 특히 화학성 독성원료의 사용으로 인한 환경호르몬의 발생으로 암, 호흡기장애 등 신체적 유해성을 가지는 등의 큰 문제점이 있었다.
However, paints coated on steel pipes are manufactured using raw materials extracted from petrochemicals, so it is difficult to produce industrial wastes generated during the production of raw materials, and to treat wastes that do not decompose, causing environmental pollution, and especially by using chemical toxic raw materials. Due to the occurrence of environmental hormones, there was a big problem such as having a physical hazard such as cancer, respiratory disorders.

또한, 생산에서 도장까지 발생되는 휘발성 유기화합물, 중금속 등 발암성물질을 함유하고 있어 도포 후에도 이에 포함된 납, 크롬, 카드뮴 등의 중금속이 계속 유출되므로 중금속 중독과 암을 유발하게 될 뿐만 아니라 종래와 같은 도료가 도장된 강관을 이용하여 상수도관 등으로 사용하는 경우에 식수에 유해성분 또는 중금속이 포함될 우려가 있었다.
In addition, it contains carcinogenic substances such as volatile organic compounds and heavy metals that occur from production to painting, and heavy metals such as lead, chromium, and cadmium are continuously leaked even after application, thereby causing heavy metal poisoning and cancer. When used as a water pipe using a steel pipe coated with the same paint, there was a fear that harmful components or heavy metals were included in the drinking water.

그리고 종래에는 강관의 내면 도장장치와 외면 도장장치가 별도의 구비되어 도장이 이루어지도록 한 구성이므로 도장장치의 설치공간 및 설비 비용이 과다하게 발생할 뿐만 아니라 강관의 내,외면 도장을 별도로 진행해야 하는 작업공정으로 작업생산성이 떨어지게 되는 등 문제점이 있었다.
In addition, since the inner coating device and the outer coating device of the steel pipe are conventionally provided so that the painting is performed, the installation space and equipment cost of the coating device are excessively generated, and the work that has to be performed separately for the inner and outer coating of the steel pipe. There was a problem such that the work productivity is reduced by the process.

본 발명은 이러한 문제점을 해결하기 위하여 안출한 것으로, 두 종류의 이액형 도료를 각각 저장하는 도료 저장탱크에서 한 쌍의 공급호스가 도장건의 선단부 이액형 분사노즐에 각각 연결되어 이액형 분사노즐에서 식물성 폴리우레탄 도료와 속건제가 교차 분사되어 혼합되도록 한 수단으로 속건형 폴리우레탄 도료의 도장이 이루어지도록 하고, 상기 속건형 폴리우레탄 도료는 내면 도장건과 외면 도장건에 의해 동시에 분사되어 도장이 이루어지도록 함으로서 인체에 무해하고 내염성 및 내후성이 우수한 친환경 식물성 폴리우레탄 강관을 간편하고 신속하게 도장할 수 있고 설비의 최소화 및 공간활용성을 높일 수 있도록 한 식물성 폴리우레탄 도료의 강관 도장장치를 제공함에 있다.
