Description

활성탄소를 포함하는 필터 및 이를 이용한 휘발성유기물질을 배출하는 대상체의 처리방법A filter containing activated carbon and a treatment method for an object discharging volatile organic substances using the same
본 발명은 활성탄소를 포함하는 필터 및 이를 이용한 휘발성유기물질을 배출하는 대상체의 처리방법에 관한 것이다.The present invention relates to a filter containing activated carbon and a method of treating an object using the same for discharging volatile organic substances.
새차 증후군이란 신차 출고 시 배출되는 휘발성 유해물질인 포름알데히드, 톨루엔, 벤젠 등 인체 유해 성분인 발암 물질과 환경 호르몬(프탈레이트계)등 새 차 증후군의 중요 물질인 VOCs는 중기압이 높아 대기 중으로 쉽게 증발되고, 대기 중에서 태양광의 작용을 받아 광화학 반응을 일으켜 광화학물질로 변환하여 대기 중 스모그를 생성하며 인체에 두통, 어지러움증, 구토 등을 야기시킨다.New car syndrome refers to carcinogenic substances that are harmful to the human body such as formaldehyde, toluene, and benzene, which are volatile harmful substances emitted when a new car is shipped, and VOCs, which are important substances for new car syndrome such as environmental hormones (phthalates), evaporate easily into the atmosphere due to high medium pressure. In the atmosphere, under the action of sunlight, it causes a photochemical reaction, converts it into photochemical substances, creates smog in the air, and causes headaches, dizziness, and vomiting in the human body.

이하의 설명에서는 자동차의 시트를 대상으로 처리방법을 설명하나, 본 발명의 대상체는 이에 한정되지 않고, 모든 휘발성유기물질 배출장소에 사용될 수 있다.In the following description, a treatment method for a car seat will be described, but the subject of the present invention is not limited thereto, and may be used in any volatile organic material discharge site.
신차에서는 휘발성유기물질이 많이 배출되며, 고객에게 인도 전에 휘발성유기물질을 제거해야 한다.A new car emits a lot of volatile organic substances, and the volatile organic substances must be removed before delivery to the customer.
먼저 도 6와 같이 자동차의 시트를 비닐로 밀봉하며, 이 때 필터(1)도 비닐 내에 위치한다. 본 명세서에서의 '밀봉'은 외부와 100% 차단되는 것을 포함하여, 일반적으로 대상체에 비닐을 씌우는 정도도 포함한다. 필터(1)의 위치 및 개수는 적절히 선택될 수 있다.First, the seat of the vehicle is sealed with vinyl as shown in FIG. 6, and at this time, the filter 1 is also located in the vinyl. In the present specification, 'sealing' includes 100% blocking from the outside, and generally includes the degree of covering the object with vinyl. The position and number of filters 1 can be appropriately selected.
밀봉 상태에서 시트에서 발생되는 휘발성유기물질은 필터(1)에 의해 처리된다. 이외에 시트에서 발생하는 냄새 성분 및 환경호르몬(프탈레이트계열)의 제거도 수행된다.VOCs generated from the sheet in the sealed state are treated by the filter (1). In addition, the removal of odor components and environmental hormones (phthalate series) generated from the sheet is also performed.
밀봉 상태는 1일 내지 60일, 1일 내지 30일 또는 1일 내지 14일 동안 수행될 수 있다. 특히 신차의 수출과정에서 선박에 선적되어 이동하는 동안 처리방법이 수행될 수 있다.The sealed state may be performed for 1 to 60 days, 1 to 30 days, or 1 to 14 days. In particular, in the process of exporting a new car, the treatment method may be performed while it is being loaded onto a ship and moved.
각 시트에 대한 밀봉 공간의 부피는 자동차 실내 부피의 1/10 내지 1/10,000, 1/100 내지 1/10,000 또는 1/100 내지 1/1,000일 수 있다. 자동차 실내보다 좁은 공간에서 휘발성유기물질이 제거되므로 제거효율이 높다.The volume of the sealing space for each seat may be 1/10 to 1/10,000, 1/100 to 1/10,000, or 1/100 to 1/1,000 of the volume of the vehicle interior. The removal efficiency is high because volatile organic substances are removed in a narrower space than the interior of a car.
밀봉 상태 유지 이후 밀봉을 해제한다.Release the seal after maintaining the sealed state.
