Kodi VOC, VOCs ndi TVOC ndi chiyani?

1. VOC

Zinthu za VOC zimatanthawuza zinthu zosakhazikika. VOC imayimira Volatile Organic compoundS. VOC m'lingaliro lonse ndi lamulo la generative organic matter; Koma tanthawuzo la chitetezo cha chilengedwe limatanthawuza mtundu wa zinthu zowonongeka zomwe zimagwira ntchito, zomwe zimatha kuvulaza.

M'malo mwake, ma VOC atha kugawidwa m'magulu awiri:

Limodzi ndi tanthauzo lonse la VOC, kokha zomwe ndi zosakhazikika organic mankhwala kapena pamikhalidwe ndi kusakhazikika organic mankhwala;

Zina ndi tanthauzo la chilengedwe, ndiko kuti, zogwira ntchito, zomwe zimawononga. Ndizodziwikiratu kuti kusinthasintha ndi kutenga nawo mbali mumlengalenga wa photochemical reaction ndizofunikira kwambiri kuchokera ku chilengedwe. Osagwedezeka kapena osatenga nawo gawo mumlengalenga wa Photochemical sikutanthauza ngozi.

2.VOCS

Ku China, VOCs (zosakhazikika organic mankhwala) amatanthauza organic mankhwala ndi zimalimbikitsa nthunzi kuthamanga kuposa 70 Pa pa kutentha wabwinobwino ndi kuwira malo pansi 260 ℃ pansi pa kupsyinjika wamba, kapena organic mankhwala ndi lolingana volatilizes pa nthunzi kuthamanga kuposa kapena wofanana 10. Pa 20 ℃

Kuchokera pakuwona kuwunika kwa chilengedwe, amatanthauza ma hydrocarboni omwe si a methane omwe amazindikiridwa ndi chowunikira cha hydrogen lawi lamoto, kuphatikiza ma alkanes, aromatics, alkenes, halohydrocarbons, esters, aldehydes, ketoni ndi zinthu zina zachilengedwe. Nayi chinsinsi chofotokozera: VOC ndi VOCS kwenikweni ndi gulu limodzi la zinthu, ndiye kuti, Volatile Organic Compounds chidule, chifukwa Volatile Organic Compounds ambiri chigawo chimodzi, kotero VOCS yolondola kwambiri.

3.TVOC

Ofufuza amtundu wa mpweya wamkati nthawi zambiri amatchula zinthu zonse zamkati zamkati za Organic zomwe amayesa ndikusanthula ngati TVOC, yomwe imayimira chilembo choyamba cha mawu atatu a Volatile Organic Compound, Mawu omwe amayezedwa onse amadziwika kuti Total Volatile Organic CompoundS (TVOC). TVOC ndi imodzi mwa mitundu itatu ya kuipitsa yomwe ikukhudza mpweya wamkati.

Bungwe la World Health Organization (WHO,1989) linanena kuti zinthu zonse zowonongeka (TVOC) zimakhala zosasunthika zomwe zimakhala ndi malo osungunuka pansi pa kutentha ndi kutentha pakati pa 50 ndi 260 ℃. Ikhoza kukhala nthunzi mumlengalenga kutentha firiji. Ndi poizoni, wokwiyitsa, carcinogenic ndi fungo lapadera, lomwe lingakhudze khungu ndi mucous nembanemba ndikuwononga kwambiri thupi la munthu.

Kufotokozera mwachidule, mgwirizano pakati pa atatuwo ukhoza kuwonetsedwa ngati mgwirizano wophatikizira:
