COD ndi gawo lofunikira lomwe limagwiritsidwa ntchito poyesa kuchuluka kwa zodetsa zam'madzi mu thupi lamadzi. Imayesa zofuna zonse zokongoletsera pomwe mitundu yonse yazomera imaphika ndi oxidid ndi oxidant ya oxidant (nthawi zambiri potaziyamu diokromate) m'mikhalidwe ya acidic. Ma COD Phunziro amatha kupereka chidziwitso pazomwe zingachitike pangozi zachilengedwe zachilengedwe, monga momwe organic amakhala amayambitsa oxygen kuchepa madzi, omwe amatha kusokoneza moyo wa kuoneka.
Kupanga kwa mababu a cod
CATT CATTmakamaka amapangidwa makamaka pagalasi yazibowo, lomwe limadziwika chifukwa cha kuchuluka kwake kwamphamvu ndi kugwiritsa ntchito mankhwala. Izi ndizofunikira kwambiri monga momwe chimbudzi zimafunikira kuti muthe kutentha zitsanzo mpaka 150 ° C kwa maola awiri. Machubu oyeserera amakhala ndi zipwirikiti zotsekemera zomwe nthawi zambiri zimakhala ndi PTFF
Mawonekedwe Ofunika
Zinthu: Magalasi a Borosiltate amathandizira kukhazikika komanso kukana kuwonda kwamafuta ndi kuchuluka kwa mankhwala.
Kapangidwe: Kamangidwe kamene kamapangitsira kumathandizira kusindikiza kotetezedwa nthawi yotentha kwambiri.
Kukula kwa masamba: machubu a cod amabwera kumachubu osiyanasiyana ndi mphamvu zokhala ndi mayunitsi osiyanasiyana ndipo amayembekeza ma cod, kuchokera kutsika (3-150 mg \ / l).
Njira Yogalukira
Njira yoyesera ya cod imaphatikizapo magawo angapo:
Kukonzekera zitsanzo: Sampu yamadzi imasonkhanitsidwa ndikusungidwa ndi sulfuric acid kuti muchepetse zinthuzo.
Anzeru: voliyumu yoyeza (nthawi zambiri 2 ml) ya chitsanzo chimasinthidwa kukhala chubu chokonzekera coud.
Chimbudzi:Chubu choyeseraimayikidwa mu cod riyakitala ya ma 150 ° C kwa maola awiri. Munthawi imeneyi, zinthu zachilengedwezo zili ndi otaziyamu dichromate m'malo acidic.
Muyezo: Pambuyo pa chimbudzi, njira yothetsera vutoli imayesedwa pogwiritsa ntchito mawonekedwe a mawonekedwe (nthawi zambiri kuzungulira 600 nm) kuti mudziwe kuchuluka kwa mankhwala ochulukirapo.
Njira iyi imalola kuwunika kwamadzi komwe poyerekeza ndi kuchuluka kwa oxygen kumafuna, komwe kumatenga masiku angapo kuti apereke zipatso.

Mapulogalamu a machubu a cod
1. Chithandizo chamadzi
Mu mankhwala osungiramo zinyalala, kuyesedwa kwa CAD ndikofunikira kuti muwonetsere mphamvu ya mankhwala. Poyesa kuchuluka kwa cod asanachitike komanso pambuyo pa chithandizo, ogwira ntchito amatha kuwunika ngati malowo mwazomwe akupanga oipitsa opangidwa ndi madzi onyansa. Izi ndizofunikira pakukonzanso njira ndikuwonetsetsa kuti azigwirizana ndi malamulo azachilengedwe omwe amapereka malire oyenerera.
2. Kuyang'anira zachilengedwe
Mabungwe azachilengedwe amagwiritsa ntchito kuyesa kwa COD kuti awonetsere bwino madzi m'mitsinje, nyanja, ndi matupi amadzi. Kuyesa pafupipafupi kumathandizira kuzindikira magwero a ndege ndikuwunika zachilengedwe zam'madzi zam'madzi. Mitengo yapamwamba ya code imatha kuwonetsa kuipitsidwa kwa mafakitale a mafakitale kapena kuthamangitsidwa kwazinthu zaulimi, kumapangitsa kufufuza kwina ndikuyesetsa kukonzanso.
3.
Maudindo ambiri akhazikitsa malire a cod m'madzi omwe amatulutsidwa madzi kuti ateteze zachilengedwe zachilengedwe. Mwa kuchititsa mayeso a cod nthawi zonse pogwiritsa ntchito njira zokhazikika ngati machubu a cod, zomera zothandizira zimatha kuwonetsa kutsatira malamulo awa ndikupewa kubwezeretsa kapena kuchitapo kanthu mwalamulo.
4. Kufufuza ndi Kukula
Mu maphunziro a kafukufuku komanso mafakitale,CATT CATTamagwiritsidwa ntchito mu maphunziro omwe akufuna kupanga matekinoloje atsopano a zinyalala kapena kumvetsetsa machitidwe oipitsa okhala m'malo osiyanasiyana. Kukhazikitsa molondola kwa cod ndikofunikira kuti muchepetse kugwira ntchito kwa njira zatsopano kapena kuyerekezera njira zosiyanasiyana zamankhwala.
Njira zabwino zogwiritsira ntchito machubu a cod
Kuonetsetsa zotsatira zolondola mukamagwiritsa ntchitoCATT CATT, ndikofunikira kutsatira machitidwe abwino:
Kupewa kuipitsidwa: onetsetsani kuti zida zonse ndi zoyera komanso zaulere kuchokera kuwonongeka musanagwiritse ntchito.
Kugwira bwino ntchito: Gwiritsani ntchito zida zoyenera zoteteza (PPE) pogwiritsa ntchito zoopsa zomwe zili mkati mwa machubu oyeserera.
Katswiri wodziwika: Katswiri wa calibrate pafupipafupi zomwe zimagwiritsidwa ntchito poyesa kuyanjana.
Tsatirani Malangizo Opanga: PANGANI ZOPHUNZITSIRA KWAULERE KWA OGWIRA NTCHITO YOPHUNZITSIRA MALO OGULITSIRA, nthawi yanjinda, komanso matenthedwe kutentha.
Mapeto
CATT CATTndi chida chofunikira kwambiri pakuwunika kwachilengedwe, kupereka deta yovuta pamadzi abwino ndi kuipitsidwa. Mapangidwe awo otukuka amawathandizira kuti athe kupirira zofunika poyesa mikhalidwe yomwe ikufotokoza molondola zomwe ndizofunikira kutsata madzi ndi chilengedwe. Monga malamulo okhudza mpweya wamadzi amayamba kuvutika kwambiri, kuyezetsa kwa cod kudzapitilirabe kuchita mbali yofunika yoteteza zachilengedwe ndi thanzi la anthu kudzera pazomwe mwadziwitsa zida zodalirika.
Kuti mumvetsetse momwe ma Cilod a Cials amagwiritsa ntchito magetsi, chonde onani nkhaniyi: "Mfundo yogwira ntchito ya cood vial."
