According as industrial structure is highly developed, various exhausting sources of air pollution materials are generated and kinds of exhausted materials are also increased compared to the past. Therefore, by exposed to various pollution materials, many adhesive effects occur and especially, rapidly increased vehicles, petrochemical product related facilities, etc. mainly discharge volatile organic compounds (hereupon, refer to “VOC”), which adhesively influence to health and environment. Therefore, many studies have been progressed in order to reduce and prevent it.
Because of high vaporizing pressure, VOC is easily vaporized to the air and when it coexists with nitrogen oxides in the air, sun ray causes photochemical reaction between them. VOC representatively indicates all materials to generate photochemical smog
VOC’s environmental importance can be summarized by two aspects
First, just like aromatic hydrocarbon and halogen hydrocarbon, it is directly harmful for human
Second, like Aliphatic hydrocarbon (especially, olripin family), it is not too much harmful to human directly but because it is related to nitrogen oxides’ photolysis reaction in the air and secondly, it namely plays role as smog precursors to trigger oxidizing substances such as ozone and aldehyde family.
As for U.S. Environment Protection Agency (EPA) limits VOC exhaust less than 500 ppm and according to Clean Air Act (CAA), it regulates valve’s exhausted amount on 189 kinds of toxic VOC below 100 ppm
In the case of Korea, VOC regulation was introduced and atmosphere environment conservation law reflected regulation base on VOC according to atmosphere environment regulated area appointment in 1995 and then, Yeocheon, Ulsan, Mipo, and Onsan industrial complexes were appointed as atmosphere conservation special area and also, atmosphere conservation regulated areas were appointed around metropolitan area.
We have produced industrial sealing (gasket and packing) product for last 22 years and by establishing Kukil INNTOT annexed “Korea Nano & Seal Industrial R&D center”, in order to examine and solve bottleneck of environment and factory operation according to VOC leakage in the aspect of customer, we possess and operate gasket/packing test equipment such as UTM(Gasket Leakage Test M/C), Steam Test M/C, Gasket Vibration Test M/C, VOC Packing Test M/C, Helitest, etc. as well as make an effort to develop excellent products and localize foreign products.
As a result, we developed VOC packing and supply them to many companies domestically and oversea and also, their excellent performance on VOC leakage prevention is recognized |
