Li-TVOC ke Eng?
Li-TVOC (Metswako yohle ya Organic e Fetohang) e bua ka kakaretso ea lik'hemik'hale tsohle tse phelang tse feto-fetohang moeeng. Li kenyelletsa:
Li-alkanes-e lokollotsoeng ho tsoa ho pente, likhomaretsi, le lintho tse ka hare tsa likoloi (polasetiki, rabara).
Li-Alkenes-e teng malapeng a ka thoko ho tsela (mosi oa likoloi), libakeng tsa ho tsuba, kapa likaracheng tse nang le lihlahisoa tsa rabara.
Li-hydrocarbon tse nkhang hamonate-e ntšoang ka pente ea lebota, thepa ea ka tlung e ncha, lisalon tsa manala le li-workshop tsa khatiso.
Li-hydrocarbon tse nang le halogenated-disebediswa tsa ho hlwekisa tse ommeng le dikhitjhine tse sebediswang dihlahiswa tsa ho hlwekisa tse thehilweng hodima dihlahiswa tse qhibidihisang.
Li-aldehyde le li-ketone-mehlodi e meholo e kenyelletsa thepa ea ka tlung ea lehong e entsoeng ka boenjiniere, li-salon tsa manala le mosi oa koae.
Li-Ester-e fumanoa litlolong, likamoreng tsa bana tse tletseng lintho tsa ho bapala, kapa ka hare ho mekhabiso e khabisitsoeng ka thepa ea PVC.
Li-VOC tse ling li kenyelletsa:
Joala (methanol e tsoang ho dihlapolli tsa pente, ethanol e tswang moyeng wa jwala),
Li-ether (li-ether tsa glycol ka har'a lipente),
Li-amine (dimethylamine e tsoang ho li-preservative le sesepa sa ho hlatsoa).
Hobaneng o lokela ho beha leihlo li-TVOC?
Li-TVOC ha se ntho e le 'ngoe e silafatsang empa ke motsoako o rarahaneng oa lik'hemik'hale tse nang le mehloli e fapaneng. Maemo a holimo a ka lematsa bophelo ba batho hampe:
Ho pepesehela nako e khutšoanyane-ho opa ha hlooho, ho teneha ha mahlo/nko.
Ho pepesehela nako e telele-kotsi ea kankere, mathata a tsamaiso ea methapo, le ho fokola ha sesole sa 'mele.
Tlhokomelo e bohlokoa hobane:
Ka tlung-tekanyo ea nako ea sebele e lumella moea o kenang, ho sefa (mohlala, khabone e butsoeng), le taolo ea mohloli (ho sebelisoa thepa e sireletsang tikoloho).
Kantle-ho lemoha ho thusa ho hlwaya mehlodi ya tshilafatso, ho tshehetsa tokiso, le ho fihlela melao ya tikoloho.
Esita le libakeng tse sa nchafatsoang, mesebetsi ea letsatsi le letsatsi (ho hloekisa, ho tsuba, ho pheha, ho senya litšila) e lokolla maemo a tlase a VOC, e leng se ka bakang mathata a sa foleng a bophelo bo botle ha nako e ntse e ea. Tlhokomelo ea saense e fetola likotsi tsena tse sa bonahaleng hore e be mabaka a laolehang.
Li-sensor tsa TVOC li sebetsa joang?
Tšebeliso ea lisebelisoa tsa ho beha leihlo tsa TVOCli-sensor tsa khase tse tsoakiloeng tse amehang habonolo ke ditshila tse ngata tse feto-fetohang, ho kenyeletswa:
Formaldehyde

Li-sensor tsena li ka:
Fana katlhokomelo ea nako ea sebele le ea nako e telele.

Lipotso Tse Botsoang Khafetsa
1. Li-sensor tsa TVOC li lemoha eng?
Ba lekanya kakaretso ea metsoako ea lintho tse phelang e feto-fetohang, empa eseng likhase tse itseng.
2. Na disensara tsa TVOC di nepahetse?
Ho nepahala ho itshetlehile ka mofuta wa sensor le tlhahlobo ya moetsi. Le hoja boleng bo felletseng bo ka fapana, tshebediso e tsitsitseng e fana ka mekgwa e tshepahalang ya tlhokomelo.
3. Na disensara tsa TVOC di hloka tlhokomelo?
E. Disensara tsa PID di hloka tlhahlobo ya selemo le selemo; disensara tsa semiconductor hangata di hloka tlhahlobo botjha dilemo tse ding le tse ding tse 2-3.
4. Na disensara tsa TVOC di ka lemoha dikgase tsohle tse kotsi?
Tjhe. Bakeng sa ditshila tse itseng, ho hlokahala di-sensor tse inehetseng tsa khase e le nngwe kapa tsa khase e ngata.
5. Li-sensor tsa TVOC li sebelisoa hokae?
Malapeng, liofising, likolong, lipetleleng, mabenkeleng a maholo, libakeng tsa lipalangoang, likoloing, lifemeng le litsamaisong tsa moea.
6. Na di-sensor tsa TVOC di loketse tshebediso ya lapeng?
E. Li bolokehile, li bonolo ho li kenya, 'me li fana ka litemoso tsa boleng ba moea ka nako ea sebele.
Qetello
Li-sensor tsa TVOC li bapalakarolo ea bohlokoa ho sireletseng bophelo bo botle, ho ntlafatsa boleng ba moea, le ho netefatsa polokeho libakeng tsa indasteri le tsa letsatsi le letsatsi. Ho tloha malapeng le liofising ho ea likoloing le lifekthering, li fetola "litšokelo tse sa bonahaleng" hore e be lintlha tse ka lekanngoang, tse matlafatsang batho ho nka mehato e potlakileng ho ea tikolohong e phetseng hantle.
