Mafunso Ofunsidwa Kawirikawiri a Dichloromethane: Chidziwitso Chofunikira cha Chitetezo cha Chosungunulira Chodziwika Bwino

Dichloromethane ndi mankhwala osungunuka omwe amagwiritsidwa ntchito kwambiri m'mafakitale opanga, kukonza, ndi kuyeretsa tsiku ndi tsiku. Ndi kusungunuka kwamphamvu, kusasinthasintha mwachangu, komanso poizoni wochepa, imagwiritsidwa ntchito kwambiri pakuyeretsa, kuchotsa, kukonza zokutira, ndi zina. Komabe, ogwiritsa ntchito wamba ambiri ndi ogwira ntchito kutsogolo ali ndi chidziwitso chochepa cha izi, nthawi zambiri amasokonezeka ndi zoopsa zake zachitetezo, zoletsa kugwiritsa ntchito, ndi malangizo oteteza. Nkhaniyi imayankha mafunso omwe amafunsidwa kawirikawiri okhudza dichloromethane mu mtundu wa Mafunso ndi Mayankho, kuthandiza anthu kumvetsetsa ndikugwiritsa ntchito mankhwala opangira awa mwasayansi komanso motsatira malamulo.

1. Kodi dichloromethane ndi chiyani, ndipo makhalidwe ake oyambira ndi otani?

Dichloromethane (DCM), yokhala ndi formula ya mankhwala CH₂Cl₂, ndi madzi achilengedwe opanda mtundu, owonekera bwino, komanso osasunthika kwambiri okhala ndi fungo lokoma pang'ono. Monga halogenated hydrocarbon compound, imasungunuka bwino kwambiri ndipo imatha kusungunula mafuta, utomoni, ndi rabara bwino, komanso kuchotsa zinthu zosiyanasiyana zachilengedwe. Poyerekeza ndi zosungunulira zochokera ku trichloroethylene ndi benzene, dichloromethane ndichosayaka moto ndi chiopsezo chochepa kwambiri cha kuphulika, zomwe zimapangitsa kuti ikhale m'malo mwa zosungunulira zamafakitale zomwe zimayaka moto. Kusinthasintha kwake kwakukulu kumapangitsa kuti mpweya utuluke mofulumira kutentha kwa chipinda, zomwe zikutanthauza kuti kupuma ndiko ngozi yaikulu yachitetezo chake.

2. Kodi ntchito zazikulu za dichloromethane m'moyo watsiku ndi tsiku ndi m'mafakitale ndi ziti?

Dichloromethane imakhudza zochitika zosiyanasiyana zamafakitale ndi za anthu wamba. M'mafakitale, imagwira ntchito ngati chotsukira mafuta komanso chotsukira molondola zida zamagetsi, zida zamagetsi, ndi nkhungu. Imagwiritsidwanso ntchito ngati chosungunula chotulutsa mafuta mu mankhwala ndi kukonza chakudya kuti ichotse zosakaniza zogwira ntchito kuchokera ku zinthu zopangira. M'moyo watsiku ndi tsiku, zochotsa utoto zambiri, zotsukira zomatira, ndi zotsukira zachikopa zimakhala ndi dichloromethane ngati chosakaniza chachikulu. Kuphatikiza apo, imagwiritsidwa ntchito popanga mafiriji ndi zinthu zotulutsa thovu, zomwe zimagwira ntchito ngati chosungunula chofunikira kwambiri m'makampani opepuka..

3. Kodi dichloromethane ndi poizoni, ndipo imayambitsa zoopsa ziti pa thanzi?

Maganizo olakwika ambiri ndi akuti dichloromethane ndi yotetezeka kwathunthu chifukwa cha poizoni wake wochepa. Ndipotu, ngakhale kuti imayikidwa m'gulu la mankhwala oopsa,Kupuma mpweya wambiri nthawi yayitali komanso kuwononga thupi kwambiri kungayambitse kuwonongeka kwakukuluKupezeka ndi zinthu zambiri kwa kanthawi kochepa kumakwiyitsa maso, mphuno, ndi pakhosi, zomwe zimapangitsa kuti munthu azungulire, avutike mutu, achite nseru, chifuwa chikalimba, komanso achite kutopa. Pa milandu yoopsa, izi zimafooketsa dongosolo la mitsempha, zomwe zimapangitsa kuti munthu agone tulo komanso asokonezeke.

Kupezeka pamlingo wotsika kwa nthawi yayitali kumabweretsa mavuto obisika komanso osatha. Kumasokoneza ntchito za chiwindi ndi impso nthawi zonse komanso kusokoneza kagayidwe kachakudya m'thupi la munthu. Kukwiya kwa kupuma kosalekeza kungayambitsenso pharyngitis ndi bronchitis. Chodziwika bwino n'chakuti, dichloromethane yomwe imapumidwa imasinthidwa kukhala zinthu zoopsa m'thupi la munthu. Poizoni wosonkhanitsidwa amatha kuwononga dongosolo la hematopoietic ndi mitsempha, zomwe zimapangitsa kuti kukumbukira kuchepe komanso kusazindikira m'miyendo. Pakadali pano, dichloromethane imalembedwa ngati khansa yomwe imaganiziridwa kuti imayambitsa matenda a khansa m'thupi la munthu, yomwe imafuna kuwongolera nthawi yomwe imapezeka komanso kuchuluka kwa mankhwalawa.

4. Ndi ntchito ziti za tsiku ndi tsiku zomwe zimaika pachiwopsezo chachikulu?

Ngozi zambiri zachitetezo zimachokera ku ntchito zosazolowereka. Choyamba, kugwiritsa ntchito zotsukira zokhala ndi DCM kapena zochotsa utoto m'malo otsekedwa, opanda mpweya wabwino kumayambitsa kusonkhanitsa nthunzi ndipo kumabweretsa poizoni mosavuta. Chachiwiri, kukhudzana mwachindunji ndi dzanja lopanda kanthu kumawononga chitetezo cha khungu, zomwe zimapangitsa kuti khungu likhale louma, lofiira, komanso likhale ndi ziwengo, pomwe poizoni amatha kulowa pakhungu ndikulowa m'magazi. Kuphatikiza apo, kusakaniza dichloromethane ndi ma acid amphamvu kapena alkali amphamvu kumayambitsa zotsatira za mankhwala ndikupanga mpweya woopsa wowononga, zomwe zimapangitsa kuti pakhale zoopsa ziwiri zachitetezo.

5. Kodi chithandizo chadzidzidzi chimachitika bwanji munthu akakumana ndi dichloromethane?

Ngati mwapumira nthunzi yochuluka, pitani nthawi yomweyo kumalo opumira bwino, masulani zovala, ndipo pitirizani kupuma bwino. Pitani kuchipatala mwamsanga ngati chizungulire kapena kupuma movutikira. Kuti mukhudze khungu, tsukani bwino malo okhudzidwawo ndi madzi othamanga ndipo sinthani zovala zodetsedwa kuti mupewe dzimbiri lopitirira. Ngati madziwo alowa m'maso, tsukani mosalekeza ndi madzi oyera kwa mphindi zoposa 15 popanda kukanda m'maso, ndipo fufuzani dokotala nthawi yomweyo.

6. Kodi mungateteze bwanji anthu omwe akhudzidwa ndi ngozi nthawi yayitali tsiku lililonse?

Chitetezo chogwira ntchito chimadalira mpweya wokwanira, njira zodzipatula, ndi ntchito zokhazikika. Malo ogwirira ntchito m'mafakitale ayenera kukhala ndi makina opumira mpweya kuti achepetse kuchuluka kwa zosungunulira mpweya. Ogwira ntchito ayenera kuvala zophimba mpweya, magolovesi osasungunuka, ndi magalasi oteteza kuti asawonekere pakhungu mwachindunji ndi kupuma. Kwa ogwiritsa ntchito wamba, nthawi zonse sungani mawindo otseguka mukamagwiritsa ntchito ndipo pewani kugwira ntchito kwa nthawi yayitali m'malo otsekedwa m'nyumba. Ogwira ntchito omwe ali ndi nthawi yayitali ayenera kutenga nawo mbali pazoyezetsa zaumoyo kuntchito kuti apewe kuwonongeka kwa chiwindi, impso, ndi dongosolo lamanjenje.

7. Kodi dichloromethane imayambitsa kuipitsidwa kwa chilengedwe? Kodi kutaya zinyalala zamadzimadzi motsatira malamulo okhwima?

Dichloromethane yosungunuka imakhala mankhwala osungunuka achilengedwe (VOCs) ndipo imadetsa mlengalenga. Kutaya zinyalala molakwika kumalowa m'nthaka ndi pansi pa nthaka. Chifukwa cha kuwonongeka kwachilengedwe, kumayambitsa kuipitsidwa kwa madzi ndi nthaka kwa nthawi yayitali. Dichloromethane yosungunuka m'mafakitale iyenera kusonkhanitsidwa ndikutsekedwa mofanana, ndikutayidwa ndi mabungwe odziwa bwino ntchito. Kutaya ndi kutaya zinyalala mwachisawawa n'koletsedwa kwambiri kuti tipewe kuwonongeka kwa chilengedwe.

Pomaliza, dichloromethane ndi chinthu chamtengo wapatali kwambiri chomwe chimasungunuka m'mafakitale chomwe sichingayake kapena kuphulika, komabe chimayambitsa poizoni ndi zoopsa paumoyo. Kwa ogwira ntchito m'mafakitale komanso ogwiritsa ntchito wamba, kuzindikira makhalidwe ake, kupewa ntchito zoopsa, komanso kugwiritsa ntchito njira zodzitetezera zasayansi kungathandize kwambiri kugwiritsa ntchito kwake komanso kuteteza thanzi la munthu komanso chitetezo cha chilengedwe.
