Ikhwalithi yomoya, kungakhathaliseki ukuthi ingaphakathi noma ngaphandle, ithintwa kakhulu yizinhlanganisela eziphilayo eziguquguqukayo (ama-TVOC). Lezi zingcolisi ezingabonakali zikhona kabanzi futhi zibeka izingozi ezinkulu zempilo. Amadivayisi okuqapha i-TVOC ahlinzeka ngedatha yesikhathi sangempela ngamanani e-TVOC, okwenza kube lula amasu okungenisa umoya nokuhlanza ukuthuthukisa ikhwalithi yomoya. Kodwa kanjani ngempelainzwa yezwiumsebenzi? Ake siwuchaze kahle.
Ayini ama-TVOC?
Ama-TVOC (Ama-Total Volatile Organic Compounds) kubhekisela ekuqoqweni okuphelele kwawo wonke amakhemikhali e-organic aguquguqukayo emoyeni. Ahlanganisa:
Ama-Alkanes-kukhishwe ngopende, izinto zokunamathisela, kanye nezinto zangaphakathi zezimoto (ipulasitiki, irabha).
Ama-Alkenes-kukhona ezindlini eziseceleni komgwaqo (emotweni ekhipha uthuli), ezindaweni zokubhema, noma emagaraji anemikhiqizo yerabha.
Ama-hydrocarbon anuka kamnandi-okuphuma ngopende wodonga, ifenisha entsha, izindawo zokucwala izinzipho, kanye nezindawo zokunyathelisa.
Ama-hydrocarbon afakwe i-halogen-okuvamile eduze kwemishini yokuhlanza eyomile kanye namakhishi kusetshenziswa imikhiqizo yokuhlanza esuselwe ku-solvent.
Ama-Aldehydes nama-ketone-imithombo emikhulu ihlanganisa ifenisha yokhuni eyenziwe ngobunjiniyela, izindawo zokucwala izinzipho, kanye nentuthu kagwayi.
Ama-Esters-kutholakala ezimonyweni, emakamelweni ezingane agcwele amathoyizi, noma ngaphakathi okuhlotshiswe ngezinto ze-PVC.
Amanye ama-VOC afaka:
Utshwala (i-methanol evela ezincibilikisini zopende, i-ethanol evela ekushiseni kotshwala),
Ama-Ether (ama-glycol ethers ezimbozweni),
Ama-Amine (i-dimethylamine evela ezilondolozini kanye ne-detergents).
Kungani Kufanele Uqaphe Ama-TVOC?
Ama-TVOC awayona into eyodwa engcolile kodwa ayingxube eyinkimbinkimbi yamakhemikhali anemithombo eyahlukahlukene. Ukugxila okuphezulu kungalimaza kakhulu impilo yabantu:
Ukuchayeka isikhathi esifushane-ubuhlungu bekhanda, ukucasuka kwamehlo/kwekhala.
Ukuchayeka isikhathi eside-ingozi yomdlavuza, ukuphazamiseka kwesimiso sezinzwa, kanye nokukhubazeka kokuzivikela komzimba.
Ukuqapha kubalulekile ngoba:
Ngaphakathi-ukulinganisa ngesikhathi sangempela kuvumela ukuphefumula, ukuhlunga (isb., i-activated carbon), kanye nokulawula umthombo (kusetshenziswa izinto ezinobungani nemvelo).
Ngaphandle-ukuthola kusiza ekuboneni imithombo yokungcola, ukusekela ukulungiswa, kanye nokuhlangabezana nemithethonqubo yezemvelo.
Ngisho nasezindaweni ezingavuselelwanga, imisebenzi yansuku zonke (ukuhlanza, ukubhema, ukupheka, ukuhlakaza imfucuza) ikhipha amazinga aphansi e-VOC, okungase kubangele izinkinga zempilo ezingamahlalakhona ngokuhamba kwesikhathi. Ukuqapha kwesayensi kuguqula lezi zingozi ezingabonakali zibe yizici ezilawulekayo.
Zisebenza Kanjani Izinzwa ze-TVOC?
Ukusetshenziswa kwamadivayisi okuqapha i-TVOCizinzwa zegesi ezixubile ezizwela kakhulu ezintweni eziningi ezingcolisayo ezishintshashintshayo, okuhlanganisa:
I-Formaldehyde
I-Toluene
I-Amoniya
I-hydrogen sulfide
I-carbon monoxide
Umphunga wotshwala
Intuthu kagwayi
Lezi zinzwa zingenza lokhu okulandelayo:
Nikezaukuqapha kwesikhathi sangempela nesikhathi eside.
Ukugxila kokubonisa futhi ukhiphe izexwayiso uma amazinga edlula imikhawulo.
Hlanganisa nezinhlelo zokungenisa umoya kanye nokuhlanza ukuze uthole izimpendulo ezizenzakalelayo.
Dlulisa idatha ngokusebenzisa izixhumi zokuxhumana eziya kumaseva amafu noma izinhlelo zokuphatha izakhiwo (i-BMS).
Ukusetshenziswa Kwezinzwa ze-TVOC
Izindawo zomphakathi zangaphakathi-isetshenziswa ezinhlelweni ze-HVAC, BMS, kanye ne-IoT.
Ukuphepha kwezimboni kanye nokuthobela imithetho-vimbela ubuthi kanye nezingozi zokuqhuma ezimbonini ezisebenzisa izinyibilikisi, uphethiloli, noma upende.
Izimoto kanye nezokuthutha-qapha ikhwalithi yomoya wekhabhini futhi unciphise ukuchayeka ekukhishweni komoya ongcolile.
Izindlu ezihlakaniphile nemikhiqizo yabathengi-kuhlanganiswe nama-thermostat, ama-purifier, ngisho nezinto ezigqokwayo.

Izinzuzo kanye nokulinganiselwa
Izinzuzo
Ukutholwa kokungcola okuningi okungabizi kakhulu
Ukusetshenziswa kwamandla okuphansi, okuzinzile kokuqapha isikhathi eside
Kuthuthukisa ukuphepha emoyeni kanye nokuhambisana nemithethonqubo
Ukuxhumeka kwamafu kokulawula okuhlakaniphile

Ukusebenza kuthinteka yizinga lokushisa, umswakama, kanye nokuzulazula kwenzwa
Imibuzo Evame Ukubuzwa
1. Yini etholwa yizinzwa ze-TVOC?
Balinganisa ukuhlushwa okuphelele kwamakhemikhali e-organic aguquguqukayo, kodwa hhayi amagesi athile.
2. Ingabe izinzwa ze-TVOC zinembile?
Ukunemba kuncike ohlotsheni lwenzwa kanye nokulinganiswa komkhiqizi. Nakuba amanani aphelele angahluka, ukusetshenziswa njalo kunikeza izitayela zokuqapha ezithembekile.
3. Ingabe izinzwa ze-TVOC zidinga ukulungiswa?
Yebo. Izinzwa ze-PID zidinga ukulinganiswa kwaminyaka yonke; izinzwa ze-semiconductor ngokuvamile zidinga ukulinganiswa kabusha njalo eminyakeni emi-2-3.
4. Ingabe izinzwa ze-TVOC zingabona wonke amagesi ayingozi?
Cha. Ngokuphathelene nokungcola okuthile, kudingeka izinzwa ezinikezelwe zegesi eyodwa noma eziningi.
5. Zisetshenziswa kuphi izinzwa ze-TVOC?
Emakhaya, emahhovisi, ezikoleni, ezibhedlela, ezindaweni ezinkulu, ezindaweni zokuthutha, ezimotweni, emafektri nasezinhlelweni zokungenisa umoya.
6. Ingabe izinzwa ze-TVOC zilungele ukusetshenziswa ekhaya?
Yebo. Ziphephile, kulula ukuzifaka, futhi zinikeza izexwayiso zekhwalithi yomoya ngesikhathi sangempela.
Isiphetho
Izinzwa ze-TVOC zidlala i-indima ebalulekile ekuvikeleni impilo, ekuthuthukiseni ikhwalithi yomoya, kanye nokuqinisekisa ukuphepha ezindaweni zezimboni kanye nezansuku zonke. Kusukela emakhaya nasemahhovisi kuya ezimotweni nasemafektri, baguqula “izinsongo ezingabonakali” zibe idatha elinganisekayo, banike amandla abantu ukuthi bathathe izinyathelo zokuthatha isinyathelo sokufinyelela endaweni enempilo.
